Stamping equipment is used for drawing and forming of products, including drawing, redrawing, reverse drawing and thinning.
Drawing processing: Using the platen device and the punching force of the punch, part or all of the flat plate is pulled into the cavity of the female die to form a bottomed container. The sidewall of the container is processed parallel to the drawing direction, and the deep drawing processing of conical (or pyramidal) containers, hemispherical containers, and parabolic containers also includes expansion processing.
Re-drawing: For deep-drawn products that cannot be completed by one-time drawing, the formed product needs to be re-drawn to increase the depth of the formed container.
Reverse drawing processing: The drawing workpiece of the previous process is reversely drawn, and the inner side of the workpiece becomes the outer side, making its outer diameter smaller.
Thinning and drawing processing: The forming container is squeezed into the concave mold cavity slightly smaller than the outer diameter of the container through the punching machine, so that the outer diameter of the bottomed container is smaller and the wall thickness is thinner, which not only eliminates the wall thickness deviation, but also makes the container surface smooth. .
When using stamping equipment for metal stamping and drawing, the following 16 types are included:
1. Cylinder drawing
Drawing of cylindrical products with flanges (flanges). The flange and the bottom are both plane shapes, the side wall of the cylinder is axisymmetric, the deformation is evenly distributed on the same circumference, and the blank on the flange is deep-drawing deformation.
2. Elliptical drawing process
The deformation of the blank on the flange is tensile deformation, but the deformation amount and deformation ratio change correspondingly along the contour shape. The greater the curvature, the greater the plastic deformation of the blank; conversely, the smaller the curvature, the smaller the plastic deformation of the blank.
3. Rectangular drawing process
A low rectangular piece formed by one stretch. During stretching, the tensile resistance at the rounded corners of the flange deformation zone is greater than that at the straight edge, and the degree of deformation at the rounded corner is greater than that at the straight edge.
4. Yamagata drawing process
When the side wall of the stamping part is inclined, the side wall is suspended during the stamping process, and the mold is not attached until the end of forming. The deformation characteristics of different parts of the sidewall during the forming process are not exactly the same.

For parts made of Cr12MoV, quenching is performed after rough machining. After quenching, the workpiece has a large residual stress, which is easy to cause cracking during finishing or work. After quenching, the parts should be tempered while hot to eliminate quenching stress. The quenching temperature is controlled at 900-1020°C, then cooled to 200-220°C, air-cooled, and then quickly returned to the furnace for tempering at 220°C. This method is called hardening process, which can obtain higher strength and wear resistance. The die in the form of failure has a better effect. Tempering is not enough to eliminate quenching stress, and workpieces with complex shapes are not enough to eliminate quenching stress. Before finishing, stress annealing or multiple timely treatments should be performed to fully relieve stress.
For powder alloy steel parts such as V10 and APS23, since they can withstand high temperature tempering, a secondary hardening process can be used during quenching, quenching at 1050-1080 °C, and then tempering at 490-520 °C for several times to obtain higher impact toughness and stability, it is very suitable for molds with chipping as the main failure mode. Powder alloy steel has high cost, but good performance, and is forming a wide range of application trends.
There are three main types of grinding: surface grinders, internal and external cylindrical grinders and tool grinders. In the process of finishing grinding, the generation of grinding deformation and grinding cracks should be strictly controlled, and even very small cracks will be revealed in subsequent processing and use. Therefore, the fine grinding knife should be small, not large, the coolant should be sufficient, and the dimensional tolerance should be within 0.01mm to grind the internal parts at a constant temperature. For a 300mm long steel piece, when the temperature difference is 3°C, the material changes by about 10.8μm, 10.8=1.2×3×3 (deformation per 100mm is 1.2μm/°C). The influence of this factor should be fully considered for each finishing process.
It is very important to choose the right grinding wheel when fine grinding. According to the high vanadium and molybdenum conditions of die steel, it is more suitable to choose GD single crystal corundum grinding wheel. When processing hard alloy and high quenching hardness materials, organic binder diamond grinding wheel is preferred. The organic binder grinding wheel has good self-grinding ability. The roughness of the grinding workpiece is Ra=0.2μm. In recent years, with the application of new materials, the CBN grinding wheel, that is, the cubic boron nitride grinding wheel, has a better finishing effect than other types of grinding wheels in CNC forming grinding, coordinate grinding machines, and CNC internal and external cylindrical grinding machines. During the grinding process, attention should be paid to repair the grinding wheel in time to keep the grinding wheel sharp. When the grinding wheel is passivated, it will slide and squeeze on the surface of the workpiece, causing burns on the surface of the workpiece and reducing the strength.
The processing of plate parts is mostly processed by a surface grinder. In the process of processing, long and thin plate parts are often encountered, which are difficult to process. Because in the process of processing, under the action of magnetic adsorption, the workpiece is deformed and close to the surface of the worktable. When the workpiece is removed, the workpiece will be deformed back, and the thickness measurement is consistent, but the parallelism cannot meet the requirements. The solution can be magnetic grinding. Method, the grinding block is placed under the workpiece, and the four-sided block is dead. When processing small knives and multi-blade knives, the processing does not require the block and other blocks. Direct adsorption processing can improve the grinding effect and meet the parallel requirements.
The shaft parts have rotary surfaces, which are widely used in internal and external cylindrical grinders and tool grinders. In the process of processing, the headstock and the top are equivalent to the busbar. If there is a runout problem, the machining workpiece will also have this problem, affecting the quality of the part. Therefore, the inspection of the headstock and the top should be done before processing. When grinding the inner hole, the coolant should be fully poured to the grinding contact position so that the grinding can be discharged smoothly. It is best to use a clamping process table for the processing of thin-walled shaft parts, and the clamping force should not be too large, otherwise the inner triangle deformation will easily occur around the workpiece.

Drawing and stamping is a manufacturing process that uses dies to stretch materials into final shapes by pressing metal sheets into dies. The main benefit is that it can create complex shapes quickly and efficiently. If you need metal parts with a lot of curves or complex details, this stamping may be an ideal choice. Because it can adapt to almost any design limitation, and deep drawing parts are more durable than stamping parts, because they will be slightly worn in the production process.

1. Stamping characteristics of stainless steel sheet
1. High yield point, high hardness, obvious cold work hardening effect, and prone to cracks and other defects.
2. The thermal conductivity is worse than that of ordinary carbon steel, resulting in large deformation force, punching force and deep drawing force.
3. The plastic deformation is severely hardened during deep drawing, and the sheet is easy to wrinkle or fall off when stretched.
4. The deep drawing die is easy to produce adhesion tumor, which leads to serious scratches on the outer diameter of the part.
5. It is difficult to achieve the expected shape during deep drawing.
After reading the stamping characteristics of stainless steel sheet, let’s take a look at how to solve the problem of deep drawing of stainless steel sheet. The editor believes that these problems are determined by the characteristics of stainless steel itself, which are mainly affected by the following five factors:
1. Raw material properties
2. Die structure and stamping speed
3. Mold material
4. Stamping lubricant
5. Process design
And the quality of the sheet will also affect the stamping performance, so the materials we purchase should be regular and meet the standards. For hard materials, an annealing operation should be performed before stamping to increase processability.
The above is about the processing of thin-plate stainless steel tensile parts. Have you learned it? If you don’t understand anything, you can contact the webmaster of this site, and we can communicate together!

There are many reasons for the uneven shape of punching and drawing parts. The main reasons and solutions are as follows:
1. There is no air hole on the punch.
When punching, the air in the workpiece is pressed out by the punch and cannot be discharged, which makes the shape of the drawn part uneven, which is also the reason why many people tend to ignore it. The solution is to add air vents on the punch.
2. The blank is uneven.
The surface of the blank is uneven, causing the surface of the deep drawing workpiece to be uneven. The treatment method is to replace the material with good surface quality.
3. Strong rebound of material.
The material rebounds greatly, resulting in the formation of deep-drawn parts. The solution is to increase the annealing or forming process.
4. Protruding, the mold gap is too large.
If the gap is too large, the working surface of the mold loses the straightening effect on the workpiece wall, resulting in uneven shape of the workpiece. Therefore, the mold gap must be trimmed or replaced.
5. The negative deviation of the thickness of the material is too large.
If the material is too thin, the mold gap will be relatively large, resulting in uneven shape. The material needs to be replaced with an appropriate thickness.
In the process of stamping and drawing parts, if the phenomenon of uneven shape occurs, you may first find out the reasons from five aspects.
For the side-scribing problem of drawing parts, factors such as product size, material, thickness, drawing height, etc. must be considered when designing the stamping and drawing die gap. Unreasonable die gap design will also cause scratches. For high-level or small-diameter products, multiple deep drawing operations must first be calculated when designing the die. If the process design is too small, it will also cause scratches.
As far as stainless steel products are concerned, the roughness of the punching and wire drawing of the mold also has a great influence on the surface quality of the product, and the surface of the mold should be polished as much as possible. In view of the severe deformation of stamping and drawing parts, try to choose a hydraulic press for processing. If the mechanical stamping process is too fast, it is easy to cause the surface quality of the product to not meet the requirements.
For punching and drawing parts, when selecting raw materials, materials that are easy to stretch in a soft state must be selected. For some special products, annealing while stretching can also be considered. In actual production and processing, we must pay more attention and more analysis, so that we can better solve problems when encountering problems. In fact, the processing process of stamping and drawing parts is not so complicated. For stamping parts that customers are satisfied with, we need to see more and see more. Analytics for faster resolution when problems are encountered.
The above is about the uneven appearance and side scratches of stamping parts. Various problems will occur in the process of stamping parts, but the solutions to the problems can be found in time to ensure the processing of stamping parts. Quality is the foundation of the long-term development of an enterprise. I hope the above can be helpful to readers.

1. The principle of stamping processing
Stamping parts are actually the use of punches and dies to apply external forces to sheets, strips, pipes, and profiles to cause plastic deformation or separation, so as to obtain the required shape and size of the workpiece. The processing method, the obtained workpiece It’s stamping parts.
1. Stamping parts are made by stamping under the premise of low material consumption and small consumption. Its parts are lightweight and rigid. After the plastic deformation of the plate, the internal structure of the metal is improved, and the strength of the stamping part is improved.
2. The dimensional accuracy of the stamping parts is high, and the size of the stamping parts is uniform and the same as that of the die, and the interchangeability is good. The general assembly and use requirements are well met without further machining.
3. The surface quality of stamping parts is good, the appearance is smooth and beautiful, which provides convenient conditions for surface coating, electroplating, phosphating and other surface treatments.

1. What is the reason why the punch of metal stamping parts wears too fast during the processing?
1. The gap of the metal mold is too small. Generally, the total gap of the Jianhan mold is 20%-25% of the thickness of the material plate.
2. The concave mold is not conducive to neutrality, including defects such as mold base, mold assembly and rotary tower insert sleeve.
3. The temperature of the first simulated test is too high, which is mainly caused by the long-term continuous stamping of the same mold.
4. Improper grinding method of die edge will lead to annealing and increase wear.
5. For local single-sided punching, such as step punching, punching angle or shearing force, the lateral force of the aluminum alloy door and window components will cause the punch to deviate to one side, reducing the edge gap, resulting in serious punching. Die wear. If the installation accuracy of the machine tool die is not high, the punch will deflect to the upper die, thereby damaging the punch and the die.
6. The raw materials you buy may be defective.
7. Usually there is no machine maintenance and so on.
Well, the above is the relevant content of “Is the punch of metal stamping parts worn too fast?” I hope the above content can help you!

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.

The processing materials we use include stainless steel, aluminum, copper, nonferrous metals and some alloys, which are commonly used by stamping manufacturers. Here is a brief introduction to the difference between steel stamping and copper aluminum stamping.The commonly used steel plates are carbon steel and stainless steel, and the non-ferrous metal plates include aluminum, copper and their alloys. They have high plasticity and low deformation resistance, and are suitable for cold stamping.
(1) Copper aluminum and its alloys are widely used as components of electrical equipment because of their good ductility and excellent conductivity.
(2) The stamping process of carbon steel and stainless steel is often used to manufacture equipment shells, structural parts, boxes, etc., but because of its strong stiffness, stamping oil is usually used to improve the process.

(1) The blanking and punching of precision metal stamping parts is the process of separating the blanks. The process of blanking and punching is exactly the same, but the use is different. When blanking, the separated part is the finished product, and the remaining periphery is waste; punching is to obtain the hole, the punched sheet is the finished product, and the separated part is waste. Blanking and punching are collectively referred to as punching. Both the punch and die of the blanking die have a sharp edge with a gap of 5%-10% between the punch and die to ensure that the cut is neat and less burr.
(2) Bending is to make the workpiece obtain various corners of different shapes. The working part of the bending die that bends the workpiece must have an appropriate fillet radius r to avoid cracking when the workpiece is bent.
(3) Drawing: Drawing is a process in which a flat blank is formed into a cup or box. The punch and die edges of the drawing die should be rounded to avoid cracking the workpiece. There should be a slightly larger gap between the punch and the die than the thickness of the sheet to reduce friction. In order to prevent wrinkles, the edges of the blanks are pressed by a press plate, which is a processing method that uses a die to separate or deform the sheets. Because in most cases the sheet does not need to be heated, it is also called cold stamping.

1. How to avoid damage as follows:
1. The sliding hinge cannot be made of aluminum alloy material, but stainless steel material should be used.
2. Sliding windows with a width greater than 1 meter, or doors and windows with double-glazed glass, should be equipped with double pulleys or use movable pulleys.
3. Hardware accessories should be Z-terminals, door and window locks. Handles, etc. should be installed behind the window and door frame to ensure accurate position and flexible switching.
4. When using fastening screws to install hardware, there must be a metal backing plate, and the thickness of the backing plate is at least twice the pitch of the fasteners. It cannot be used to fix plastic profiles, and non-metallic linings cannot be used.
5. The type, specification and performance of the hardware accessories used should conform to the current national standards and relevant boundaries, and should be used in conjunction with the selected plastic steel doors and windows.
6. Pay attention to maintenance after installation to avoid corrosion. When used every day, lightly close and lightly open to avoid damage caused by hard opening of the hard tube.
How to inspect metal stampings? Rockwell hardness tester is used for hardness test of metal stamping parts. Such as: small, irregularly shaped stamping parts, can be used to detect small planes, can not be used for ordinary desktop Rockwell hardness tester.
PHP series Rockwell hardness tester is especially suitable for hardness testing of such stamping parts. Aluminum alloy stamping parts are common parts in the fields of metal processing and mechanical manufacturing. The processing of stamping parts is a processing method in which metal sheets and strips are separated or formed using molds. It has a wide range of applications.
The main purpose of the hardness inspection of blanking parts is to judge whether the annealing degree of the metal plate is suitable for the processing of stamping parts in the future. In the processing of different types of stamping parts, there are requirements for plates with different hardness levels. Webster hardness tester can be used to test the processing of stamping parts. When the data exceeds 13mm, it can be replaced by a barcol hardness tester, and a barcol hardness tester can be used for pure aluminum or low-hardness aluminum alloy sheets.
As far as the stamping industry is concerned, stamping is sometimes referred to as sheet metal forming, but it is slightly different. What we call sheet molding is a forming method of plasticizing raw materials such as thin plates, collectively referred to as sheet forming. In this case, the deformation in the direction of the thick plate is generally ignored.
The reasonable planning of the mold is the basis for improving the durability of the mold. In order to improve the durability of metal stamping dies, unreasonable factors in product forming should be fed back in time during die planning. If you plan to punch a small hole metal mold, the method of adding a guide sleeve should be used to strengthen the strength of the small hole mold punching needle. Also, the guide needle should be as short as possible. Decreased length equals increased strength.
High-quality metal stamping dies and the selection of plates should be properly heat treated to improve the durability of metal stamping dies. Such as quenching, vacuum heat treatment, etc.
Fourth, the rational use of metal stamping dies can ensure processing accuracy.
In terms of hardware mold life, mold accuracy has a great influence on mold life. Before making the mold, the mold must be installed. Commissioning the mold requires locating all the holes and installing the mold prior to production. When the mold is installed, the straightness of the support surface of the mold and the fixed plate, and the uniformity of the distance between the hardware mold and the guide sleeve have strict requirements on the guiding accuracy of the guide post. The higher the manufacturing and installation accuracy, the more accurate the machined parts will be, and the higher the durability of the metal mold will be.
In order to improve the durability of the hardware blanking die, the blanking die with high precision and high rigidity should be selected. For stamping more than 30%, it is better to use the servo to control the punch. The servo is equivalent to a transformer, with constant current and stable voltage, which not only protects the durability of the machine tool, but also improves the service life of the mold.
In order to improve the durability of metal stamping dies, operators must regularly protect and maintain the dies under reasonable conditions of use. It is best to maintain and repair the metal stamping dies every day, which can effectively avoid the appearance of metal stamping dies.
According to the above related content of metal stamping die processing, metal stamping parts are light in weight, satisfactory in strength and rigidity, and can be processed into parts of various shapes and sizes according to different uses and materials, and have a wider range of applications. Hope the above content can be helpful to readers.

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.
