    By : Categories : Blog,Techniques Comment: Comments Off on What are the common problems in the processing of metal stamping parts?

    1. Some common problems and reasons in the processing of stamping parts

    1. Roller printing: It is caused by foreign matter adhering to the cleaning roller or paper feeding roller (occurs at a fixed distance). Under normal circumstances, the foreign matter printed by the roller on the sheet can be removed.

    2. Burrs: In the process of punching or chamfering, there is incomplete residual material, and burrs are generated in the part below the truncated surface of the steel plate. Based on the truncated surface, the iron powder generated here will damage the mold and produce Concave and convex.

    3. The coil may be crushed or the edge is wrinkled: When the gap between the guide rollers on the die is small, the guide rollers of the uncoiler may be wrinkled, which is caused by the unyielding balance of the coil feed.

    4. Concave and convex: The material is abnormally convex or concave due to foreign matter (iron filings, dust) mixed in the uncoiler.

    5. Sliding mark: It is caused by the sliding of the roller, which occurs when it suddenly stops or accelerates.

    When we design the mold, we must have reasonable clearance value, fillet radius and machining accuracy. When designing a bending die, effective measures should be taken to reduce the springback, and the springback should be subtracted from the die; reasonable rounded corners should be designed to prevent bending cracking. When deep drawing, use a blank holder to prevent wrinkling, and the pressure should be moderate; use appropriate lubrication to reduce the drawing resistance to prevent the die from sticking or the workpiece being pulled through.

    There are many defects in metal stamping parts, such as scratches, cracks, raised dents, burrs, oxidation, etc. In the processing of metal stamping parts, we must pay attention to these details, so as to bring greater benefits. Spinning is a metal rotary machining process. During the processing, the blank is actively rotated with the spinning die or the spinning head is actively rotated around the blank and the spinning die. hollow revolving body parts.

    Reshaping is the second reshaping of the product shape using the established tool shape. Mainly reflected in the pressing plane, spring feet, etc. In view of the elasticity of some materials, the quality of one-time forming cannot be guaranteed. Reprocessing is a basic stamping process that uses molds to separate materials. , forming and other stamping processes to prepare the blank, and can also cut and trim the formed stamping parts. Blanking is widely used in automobiles, home appliances, electronics, light industry, instrumentation, machinery, railways, communications, chemicals, textiles, aerospace and other industries. The blanking process accounts for about 50% to 60% of the entire stamping process.

    Forming process:

    (1) Bending: a plastic forming method that bends metal sheets, pipe fittings and profiles into a certain angle, curvature and shape. Bending is one of the main processes widely used in the production of stamping parts. The bending of metal materials is essentially an elastic-plastic deformation process. After unloading, the workpiece will produce elastic recovery deformation in the direction, which is called rebound. Springback affects the accuracy of the workpiece and is a technical key that must be considered in the bending process.

  • What are the common methods of precision mold processing?

    By : Categories : Blog,Techniques Comment: Comments Off on What are the common methods of precision mold processing?

    No matter what kind of precision mechanical production equipment is manufactured, it is indispensable. The whole process of precision machine manufacturing includes: CNC machining center cutting, slow wire cutting, wire cutting, cutting, milling, precision measurement, automation technology, etc.

    1. CNC cutting production and processing

    The main cavity and surface of the injection mold are cut by CNC machining center. The rapid development of the rubber mold manufacturing industry is mainly due to the independent innovation of CNC machining center cutting technology.

    2. Slow wire cutting production and processing

    Slow wire cutting technology is mainly used to process 2, 3D standard surface parts, such as various mold shells, injection molds and unmetallurgical mold parts. Among them, the production and processing of metal molds accounts for a large percentage. The production and processing of many high-precision holes such as metal mold punching dies, punching fixed plates, cavities and reversing plates is the core technology that cannot be missing from slow wire cutting. In the production of plastic molds, the applications of inserting, top, inclined top holes, clear viewing angles and rollers are commonly used. Generally speaking, the machining accuracy cannot be compared with that of metal molds.Slow-moving wire is a highly sophisticated production method. The machining accuracy of advanced machine tools is less than 3μm, and the surface roughness can reach 0.05μm. At this stage, automatic production line laser cutting of 0.02-0.03_ electrode wire can be done. The drilling efficiency can be up to about 200mm_2/min.

    3. Processing grinder

    CNC grinding machine is a kind of machine tool for deep processing of the surface of parts. Small and medium-sized tool grinders are mainly used for the production and processing of small and medium-sized mold parts, such as high-precision inserts, precision machinery manufacturing, rollers, etc. Large and medium-sized water mills are often used in the production and processing of large and medium-sized molds. At this stage, fast grinding wheels and operating tables have become a common development trend. Due to the use of professional components such as linear slides, servo motors, and hydraulic press screws, the speed ratio of the grinding wheel has been greatly developed, and the refurbishment technology of the grinding wheel has also been greatly developed.

    4. Processing center

    The mold shell production workshop is also a common machining center. Its production category is the whole gyro picture part. Due to the extreme development trend of CNC machining technology, it is easier to complete complicated rotations according to the programming, and CNC lathes can replace special tools by themselves to further improve production efficiency. With the continuous improvement of the machining accuracy and production technology of the machining center, there is even a development trend of out-feed grinding. It is often used to process components such as round inserts, supports, and accurately positioned rings in molds. Can be widely used in signature pen molds, water bottle molds, etc. In fact, the role of a good machining center will no longer be limited to “vehicles”. This is a composite CNC lathe for cutting and turning. A more complex and more complete process can even be solved at one time.

    5. Accurate measurement

    High-precision measurement is very important for the data drawing involved in the original design of the mold shell, the accurate measurement of mold manufacturing, and the accurate measurement of the mold shell repair in the middle and later stages. The role of high-precision measuring equipment is very important.

    Fast clamping of mobile phone positioning systems and automation technology.

    Mold parts often require various processes to manufacture. During this phase, the parts are constantly clamped and adjusted, which takes a lot of time. CNC lathes are still vacant, and the production capacity of expensive machinery is not being used flexibly. With the increasingly fierce market competition in the manufacturing industry. Production cuts are a growing trend. The stability and accuracy standard management system selected by foreign mold and fixture manufacturers has completed the exchange of unified standards for cutting, cold rolling, precision measurement, and wire EDM. CNC lathes for quick electrical installation and calibration in under a minute. The repeated positioning accuracy is within 3 microns, which reduces the setting time and further improves the actual running time of the CNC lathe. These have proven necessary for modern manufacturing.

    The above is about the relevant content of precision mold processing. In fact, the process of mold processing and material selection are very important, and the design methods and processing procedures required by different molds will also be different, but it is worth considering that no matter what kind Mold and processing technology need to be continuously improved. Hope the above content is helpful to readers.

  • What are the effects of materials on the processing of stamping parts?

    By : Categories : Blog,Industry Comment: Comments Off on What are the effects of materials on the processing of stamping parts?

    1. Punching

    Blanking stipulates that the raw material should have sufficient plasticity to ensure that the material does not crack during the blanking process. After punching soft materials, punching parts with smooth cross section and small slope can be obtained. The roughness of the cross section of the hard metal stamping material after punching is large, and the thick material is a ductile material, which is prone to tearing after punching.

    2. Bending

    The bending material should have sufficient plasticity and low strength limit; high plasticity sheet is not easy to crack when bending; materials with low strength limit and low elastic mold become less elastic after bending, and it is easy to obtain bending parts with accurate dimensions; for ductility Large metal stamping materials must have a large relative bending radius when bending, otherwise the material will easily crack during the entire bending process.

    3. Stretching

    The drawing process of the material not only stipulates that the drawing depth is as small as possible, the appearance is as simple and round as possible, but also that the material has good plasticity, otherwise it is easy to cause overall bending deformation, partial wrinkles, serious tensile cracking, etc.

    By : Categories : Blog,Techniques Comment: Comments Off on Talking about the stamping and blanking process of sheet metal processing

    1. Sheet metal processing stamping and blanking method

    1. Punch: After using the punch to unfold the parts on the plate in one or more steps, the plate is cut into various shapes of material parts. Its advantages are short time-consuming, high efficiency, high precision and low cost. Suitable for mass production, but the mold should be designed.

    2. Sawing machine: mainly use aluminum profiles, square tubes, drawing tubes, round bars, etc., with low cost and low precision.

    3. Shearing machine: It uses shearing machine to cut simple pieces of strips. It is mainly prepared for mold blanking and forming. The cost is low and the precision is lower than 0.2, but it can only process strips or blocks without holes and corners. material.
    4. NC CNC blanking, when NC blanking, you must first write a numerical control machining program, use programming software, and write the drawn unfolding diagram into a program that can be recognized by the NC digital drawing machine tool, allowing it to gradually cut various parts on the flat plate according to these programs. It is a flat plate of this shape, but its structure is made of a tool structure, the cost is low, and the accuracy is 0.15.

    5. Laser cutting is to use the laser cutting method to cut the structural shape of the flat plate on the large flat plate. The same NC laser program also needs to be written, and it can cut flat plates of various complex shapes. The cost is high and the precision is 0.1.

    Sheet metal processing is a key technology that sheet metal technicians need to master, and it is also an important process for sheet metal product forming. Precision sheet metal processing includes traditional cutting, blanking, bending and forming methods and process parameters, including various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technologies and new processes . Sheet metal processing of parts is called sheet metal processing.

    Stainless steel SUS304 is one of the most widely used stainless steels. Because it contains Ni (nickel), it is more resistant to corrosion, heat resistance, better mechanical properties, no heat treatment hardening, and no elasticity than steel containing Cr (chromium).

    Stainless steel SUS301Cr (chromium) content is higher, SUS304 is lower, corrosion resistance is poor, but good tension and hardness can be obtained in stamping sheet metal processing, good elasticity, mainly used for springs and anti-corrosion EMI.

    Mirror finish is used for pre-polishing and fine polishing. Pre-polishing uses a hard or harder buffing wheel to finish the finish of the stainless steel sheet metal finish and remove the roughness of the ground finish. Fine polishing uses soft to further process the pre-polished surface, remove the traces left by pre-polishing, and obtain a bright mirror surface.

    The mercerizing effect is the process of using the brushing wheel installed on the grinding and polishing machine to process the surface of the stainless steel sheet metal to obtain decorative silk-grain brushing and satin finishing.

    Sandblasting effect, using compressed air flow to spray sand or steel pellets, glass balls and other abrasives on the appearance of stainless steel sheet metal processing, so that it presents a beautiful, slightly rough sandy appearance.

    In stainless steel operations, stainless steel is usually heated by coils, lashings, welding or fire on artificial surfaces to produce black scale. This gray-black scale is relatively strong and contains two EO4 components, NiCr2O4 and NiF. In the past, it was basically removed by strong etching with hydrofluoric and nitric acids. However, due to environmental pollution, harm to human body, high corrosion and high cost, the sheet metal processing industry gradually adopts chemical methods: non-polluting pickling passivation paste and non-toxic cleaning solution are used, and inorganic additives are added for leaching at room temperature.

    Laser cutting is a metal plate made by laser cutting, and the plate thickness processed cold plate hot rolled plate is less than or equal to. 0 mm, less than 10.0 mm for stainless steel. The advantages are the thickness of the machined plate, the cutting and machining flexibility of the workpiece. The disadvantage is that it cannot be processed, the mesh is not suitable for processing, and the computing power is high.

    From the above characteristics of precision plate processing, it can be seen that compared with positive materials, calendered materials have a greater price advantage. Although there are still gaps between the quality of calendered materials and positive materials, these gaps are gradually narrowing with the improvement of calendering production process and production technology, which are also welcomed by downstream end users.

    Generally speaking, stainless steel cold-rolled materials are mainly used in civil industry. In order to maximize profits, downstream enterprises must control production costs. The price difference between the stainless steel material and the narrow strip just provides a living space for the stainless steel narrow strip industry.

  • What is the need to pay attention to in the maintenance of stamping parts?

    By : Categories : Blog,Industry Comment: Comments Off on What is the need to pay attention to in the maintenance of stamping parts?

    Today, deep drawing parts are widely used in all areas of our lives. In order to properly prolong the service life of drawn stampings, careful maintenance is required. So, what should be paid attention to when maintaining it? The following Zhejiang Baifudu Electromechanical editor will take you to understand!

    Before installation and use of stretch stamping parts, the stamping parts should be strictly inspected and the dirt should be removed, and the guide bushes and dies of the stamping parts should be carefully checked whether they are well lubricated.

    According to the installation steps of the stamping die, install the stamping die and the stamping die on the turntable to ensure that the direction of the stamping die and the stamping die are consistent, especially the stamping parts (non-circular and square) with the required direction are larger. Take care to prevent assembly errors and gaps.

    When the edges of the punch and the die of the stamping part are worn, it should be stopped in time for grinding. Otherwise, the degree of die edge wear will rapidly expand, the die wear will be accelerated, and the quality of stamping parts and die life will be reduced.

    Regularly check the turntable of the punch and the mounting base of the die to ensure the coaxial accuracy of the upper and lower turntables.

    When installing the mold, the press mold should be made of soft metal (such as copper, aluminum, etc.) to make operating tools to avoid damage to the tension part during installation.

    To ensure the service life of the stretch stamping parts, the spring of the mold should be replaced regularly to prevent the spring fatigue damage from affecting the use of the stretch stamping parts.

    The service life of stretch stamping parts depends not only on reasonable die structure, superb manufacturing accuracy, good heat treatment effect, and the correct selection of punches and the installation accuracy of stretch stamping parts, but also on the correct use, maintenance and maintenance of the die. Therefore, we must eliminate the adverse effects of various factors on the service life of drawing and stamping parts, and take effective measures to improve their service life.

  • How to improve the precision and efficiency of precision sheet metal processing?

    By : Categories : Blog,Industry Comment: Comments Off on How to improve the precision and efficiency of precision sheet metal processing?

    Precision sheet metal processing accuracy is not only a representative of the company’s processing strength, but also a test for sheet metal processing masters! Whether it is a sheet metal processing factory or an individual who performs sheet metal processing operations, it may often occur that the sheet metal processing accuracy is not ideal. Common methods to improve sheet metal machining accuracy include original error reduction method, original error compensation method, original error transfer method, original error equalization method and original error equalization method, which are commonly used methods to increase the sheet metal machining accuracy.

    Original error reduction method: In production, if errors are found, first find out the main factors that affect processing errors, and then find ways to eliminate or reduce these factors. For example, when machining parts with contours, the shape error of the forming tool and the installation error of the tool are mainly reduced.

    Original error compensation method: artificially create a new error to offset the original error in the process system. When the original error is negative, the human error takes a positive value, otherwise it takes a negative value, and try to make the two equal.

    The original error equalization method: If the positioning error is large, some original errors can be differentiated. That is, the original error is divided into N groups according to its size, the range of each group of blank errors is reduced to the original 1/n, and then the processing is adjusted according to each group.

    Original error averaging method: For parts with higher machining accuracy, the averaging method can be used. That is to compare closely related surfaces with each other, find out the differences from the comparison, and then perform mutual correction or mutual reference processing, so that the error of the workpiece surface is continuously reduced and averaged.

    Original error transfer method: Under certain conditions, the original error of the process system can be transferred to the direction of the machining error or other aspects that do not affect the machining accuracy. For example, when the accuracy of the machine tool cannot meet the machining requirements of the parts, we can find a way to transfer the geometric error of the machine tool to the aspect that does not affect the machining accuracy.

  • Do you know how to install the punch of the stamping die?

    By : Categories : Blog,Techniques Comment: Comments Off on Do you know how to install the punch of the stamping die?

    First, remove the eroded mud in the hole of the punch fixing plate of the stamping die, fix the punch on the back of the plate, and chamfer (0.5 ~ 1.5) mm × 45 along the periphery of the cavity. The size of the chamfer depends on the stress of the mold. Chamfer the edge of the punch in the die about 0.25mm×45 around the contour.

    The line cutting marks on the edge end of the punch die in the punching die are slightly ground with a fine sand bar or a diamond file to facilitate the punch to enter the fixing plate, the tail should be left at a distance without repairing, and its length should be slightly greater than or equal to the fixing plate thickness of.

    Place a contour block whose height is greater than the length of the punch under the fixing plate and press the punch into the fixing plate; this work should be divided into several steps. When the punch enters the fixing plate and can stand upright, measure the perpendicularity between each other, and then measure when entering 1/3 and 1/2 respectively. If deviation is found, it should be corrected in time, and then continue to be confirmed.If the number of punches is large or the size is small, the stripper should be aligned with the die, and the punch should be aligned with the stripper.

    When the punch enters the fixed plate, the length of the tail end is 3~5mm left, stop pressing, heat the edge line of the tail end of the punch with an oxygen-acetylene flame, and hit it quickly with a small hammer to expand the red hot part; completely cooled After that, the punch is fully pressed into the fixing plate.

    Using contoured tires, grind the upper flat and punch end flat with the lower flat of the retaining plate.

    Based on the plane of the fixed plate, the stripper plate is sleeved on the punch, so that its working surface is slightly lower than the punch, and the chamfer of the working section of the punch is ground to a sharp edge.

  • What are the procedures and principles of die assembly for metal stamping parts?

    By : Categories : Blog,Industry Comment: Comments Off on What are the procedures and principles of die assembly for metal stamping parts?

    In fact, the key to stamping die assembly is how to ensure that the relative positions of the convex and concave dies installed on the upper and lower die seats and related components can work normally, and stamping workpieces that meet product requirements.

    Therefore, it should be mentioned that the various parts to be assembled must meet the processing requirements of the assembly process for various parts; for example, the relative position dimensional accuracy and step distance accuracy of each hole must be consistent with the die and stripper; the backing plate The bolts and pins on the hole leave a large gap through the hole, which can be drilled according to the pattern size. After quenching, the upper and lower surfaces should be strictly flat.In addition to meeting the pattern requirements, the integral concave die installed on the upper die base or the lower die base should also be machined with bolt holes and pin holes. After heat treatment and finishing, it is put into assembly, and the fixed die base and guide plate should be connected. When assembling, drilling and reaming should be carried out according to the corresponding holes on the die; based on this, although the die types and structural characteristics of metal stamping parts are different, the assembly method and installation sequence are also different, but the assembly principles to be followed are the same of.

    When assembling the metal stamping part mold, it is first necessary to select the assembly reference part, use it as the assembly reference of the metal stamping part mold, and then gradually assemble other mold parts according to the reference part. The choice of the reference part depends on the structural characteristics of the metal stamping part die. The guide plate die should be selected as the guide plate that doubles as the stripper plate as the assembly reference part. The metal stamping part dies guided by the guide post usually use the concave die as the assembly reference part. The blanking and punching compound die selects the ejector plate as the assembly reference part, and the center of the die handle is the prerequisite for the alignment of the output center point of the ejector plate.

    After selecting the reference parts, assemble the components of the metal stamping part mold into a composite part according to the separate connection relationship between them, and then assemble the metal stamping part mold with the reference part as the assembly reference.

  • What are the tips for stainless steel sheet metal processing?

    By : Categories : Blog,Industry Comment: Comments Off on What are the tips for stainless steel sheet metal processing?

    When processing stainless steel sheet metal parts, in order to avoid debris from hurting people, the baffle should be lit in an appropriate position. When the surface of the workpiece needs to be polished with gauze, move the tool to a safe position and be careful not to let your hands and clothes touch the surface of the workpiece. When grinding the inner hole, don’t use your fingers to support the gauze, use a wooden stick instead, and don’t drive too fast.

    Obstructs placing objects, fixtures or workpieces on the lathe bed and spindle gearbox. Be mindful when doing homework. Obstruct tired operation, chat operation, multi-person operation, drinking operation, smoking operation.

    Adhere to the regularity of machine tools, tools, and operations, and do a good job of handover work. When cleaning the workplace after work, the power should be turned off, and various feed handles should be placed in a safe place. When turning workpieces with irregular shapes, a balance block should be installed, and the cutting should be carried out after trial rotation.

    The tool clamping should be reliable, and the protruding part of the tool head should not exceed 1.5 times the height of the tool body. The shape and specification of the gasket under the tool should be consistent with the shape and specification of the cutter body, and the gasket should be as few and flat as possible.

    In addition to installing measuring tools on the lathe that can be actively measured in operation, stop and move the tool holder to a safe position before measuring the workpiece. Ribbon chips and spiral long chips that occur during cutting should be removed with hooks in time to prevent hand pulling.

    Wear work clothes, cuffs and safety glasses before work. Female workers should wear work caps, long hair in hair care caps, and operate with gloves.

    When the chuck is loaded and unloaded on the spindle of the lathe, it must be carried out after the machine is stopped. The power of the motor must not be used to remove the chuck. Guards should be used for the protrusions of chucks, dials and core clamps that clamp the workpiece to avoid strangling clothing and other parts of the body. If there is no protective cover, care should be taken to adhere to the required interval during operation.

    When clamping the workpiece with the top, it should be noted that the center of the tip is exactly the same as the center hole of the spindle. Sheet metal work must not use damaged or angled tips. Before use, the top should be cleaned, the center hole should be clean, and the tailstock tip should be firm. When cutting slender workpieces, in order to ensure operational safety and processing quality, a tracking tool rest or center rest should be selected, and a mobile protective cover and safety signs should be set.

  • Sheet metal processing electronic chassis cabinet cleaning method

    By : Categories : Blog,Industry Comment: Comments Off on Sheet metal processing electronic chassis cabinet cleaning method

    Most customers have encountered the situation that the electronic chassis cabinet becomes dirty, so how should we clean it effectively? Today, the editor of Zhejiang Baifudu Electromechanical will give you a brief introduction.

    1. Cleaning method of sheet metal processing electronic chassis cabinet

    Primer: Fills the sand marks and micropores on the bottom layer of the workpiece, increases the adhesion of the underlying coating, and also has the function of defect indication.

    Topcoat: Topcoat is divided into single-layer paint and multi-layer paint, which is the color-determining layer and decorative protective layer. Single-layer paint is commonly known as plain paint, also known as ordinary paint, and one layer can be completed. Talking about sheet metal processing multi-layer paint is divided into silver powder series paint and pearl series paint, divided into two-layer and multi-layer construction technology. The silver powder paint is made of special aluminum material, which has high protection, strong outdoor stability and strong observability. Pearl series paint is made of high-tech materials such as mica flakes and shells. It is a high-grade paint with rich colors and strong decoration.

    Some topcoats have a very high spray quality. It is really easy to achieve clean, plump, bright, non-sagging, non-hanging, uniform luster, no leakage, no spraying, good leveling, no bottom bite, no impetuous, no color cast. It requires extensive experience and problem-solving skills.

    Intermediate primer: a very important coating part, prepare a complete and smooth working surface for the topcoat, complete the next process of the primer work, increase the adhesion of the intermediate layer, and have an isolation effect, thereby ensuring the quality stability of the topcoat.

    There should be a gap between the equipment, which is conducive to the ventilation and heat dissipation of the equipment. For precision sheet metal processing, some gaps should be left on the top of the equipment on the higher layer, so that the fan can be replaced in the future for better heat dissipation. Taller cabinets can hold more equipment, thus saving more space. After you have designed the cabinets you need to use later, reserve some spare space, because once the cabinets are purchased and installed, there will often be some additional equipment. There is no extra space for system expansion, and then it will be a headache.

  • What are the good methods for sheet metal cutting?

    By : Categories : Blog,Techniques Comment: Comments Off on What are the good methods for sheet metal cutting?

    The cutting head of the fiber cutting machine moves from top to bottom, and the laser beam prints on the plastic plate, focusing on the small print diameter. Secondly, the more troublesome method of focusing the fiber laser cutting machine is the collimator method. Although it is troublesome, it is also a commonly used method, which is to add a collimator to the output end of the fiber laser cutting machine for beam expansion. After beam expansion, the beam diameter becomes larger and the divergence angle becomes smaller, so that within the cutting working range, the beam size before focusing at the proximal and distal ends is nearly the same. The cutting head adds an independent moving lens down axis. The fiber laser cutter and the Z axis that controls the distance between the nozzle and the material surface are two separate parts. When the machine table moves or the optical axis moves, the F-axis of the beam moves from the proximal end to the distal end at the same time, so that the spot diameter of the focused beam is consistent in the entire processing area.

    Many electrical industries use laser cutting machining technology in the installation of exterior sheet metal parts and complete sets of electrical components, which improves product quality, reduces production costs, and achieves good production benefits.

    In the electrical industry, CNC laser cutting machines are mainly used to cut sheet metal parts and complete sets of electrical components.
