What are the key conditions in the forming process of stamping parts?

In fact, the so-called performance is mainly worth the forming limit, moldability and shape freezing of stamping parts. Among them, the forming limit mainly refers to the maximum deformation degree of the raw material of the stamping part during the forming process, and on the premise of ensuring no cracking. In many cases, we consider the forming limit to be the fracture resistance of the material, that is, the better the fracture resistance of the stamped material, the higher the forming limit.

And mold fit and shape freezing refers to the ability of the material to obtain the shape of the mold during the stamping process and to obtain the shape in the mold. There are many influencing factors. Pay attention to all aspects and try to avoid the influence of the material properties by the impression concept stock, so that the shape error of the stamping parts is large.

The above is the key point in the forming process of stamping parts introduced by Zhejiang Baifudu Electromechanical Editor and everyone. Do you have more understanding of stamping parts after reading it? I hope that my friends can help you after reading the above content.

What are the methods to prevent damage to metal stamping parts?

1. How to prevent the damage of metal stamping parts?

1. The type, specification and function of the selected hardware accessories should conform to the current specifications and relevant regulations, and high-quality plastic steel doors and windows should be selected to match.

2. For sliding windows with a width of more than 1 meter, or doors and windows with double-glazed equipment, it is easy to set up double pulleys, or choose to use rolling pulleys.

3. The sliding brace hinge cannot use aluminum alloy material, but stainless steel material should be used.

4. When using fastened screws to equip hardware, it is necessary to have a metal lining inside. The thickness of the lining should be at least twice the pitch of the fasteners, and must not be fastened to plastic profiles or non-metal linings.

5. After all, hardware accessories gold should be equipment, door and window locks, handles, etc. It should be assembled after the sash is framed to ensure proper orientation and movement of the switch.

6. The metal stamping equipment needs maintenance in the later stage to prevent rust and corrosion. In daily use, it should be lightly closed and lightly opened to prevent hard closing and hard opening, which will cause damage and no noise. With the current nylon wheel, it is not only noiseless, but also smoother and lighter, and its service life is not shorter than the above pulley, so that the (door) window can run normally and smoothly, choose high-quality pulley for (door) window, and inferior pulley from On the surface, the workmanship is rough, not smooth, the sliding is not active, and it is small and light.

What should be paid attention to in the processing of stamping parts?

In the whole process of stamping parts processing, we still need to pay attention to all aspects, so as to better understand the overall situation, which will be of great benefit to the future development of the entire manufacturer. What should be paid attention to in the whole process of metal stamping parts? The following Zhejiang Baifudu Electromechanical editor will take you to understand.

On the one hand, when precision stamping parts manufacturers are producing, they must also conduct corresponding inspections on their own products, so as to truly ensure that there is no problem in quality. Only if the stainless steel stamping parts processing plant does the relevant work, the entire production can be guaranteed, and many things will become easier in the future, and the entire production will become easier.
On the other hand, pay attention to the arrangement and management of stamping parts processing. The management and arrangement of the entire production and processing is still very important. If all aspects are really done well and continue to do related things, the situation of the entire manufacturer will continue to improve and improve.

Presumably many people do not know what materials are used to process metal stamping parts, because this kind of stamping parts can only be used in the hardware production industry. As long as you have a certain understanding of the hardware manufacturing industry, you should know that in the hardware processing industry, There are many metal stamping parts that must be used, so there are many stamping parts processing plants, of course, including the existence of stainless steel stamping parts processing plants.

In the current hardware manufacturing industry in my country, there are also some precision stamping parts manufacturers that produce metal stamping parts that meet the needs of hardware production and manufacturing, and these manufacturers are mainly based on some precision stamping parts. These precision stamping parts can greatly improve the product quality and production efficiency of the hardware manufacturing industry during production. Therefore, it also has a great demand in the market. Perhaps, his time and price are the same. There is also a world of difference.

How to choose high-quality stamping parts correctly?

All kinds of stamping parts can be seen everywhere in our daily life. Many domestic manufacturers have clearly seen the huge potential of the stamping market, and continue to increase their investment in the stamping market, which has effectively improved the quality of my country’s stamping products, so that they can meet the needs of the market. In the face of products produced by many manufacturers, how to choose is a headache for consumers, and which is better for high-quality stamping parts processing is a topic of concern.

When evaluating which manufacturer of metal stamping parts has better quality, the first thing to look at is the quality of the manufacturer’s products. Whether the manufacturer can produce in accordance with the relevant regulations in the production process, whether the product quality meets the relevant regulations and other related issues are all important evidences for measuring a manufacturer. When selecting, professional manufacturers let us consider the first time.

What are the basic operation methods of stamping parts processing?

First, the basic operation of stamping parts processing

The transformation of the metal stamping parts processing equipment has effectively improved the production safety and reliability of the factory. At present, the operating systems of many old hardware stamping equipment in China are not very skilled, and there are many unsafe factors in electrical control systems and equipment. If we continue to use them continuously, we will continue to carry out corresponding technical transformations. Stamping equipment manufacturers must improve product design in order to ensure the safety and reliability of stamping equipment.

Professional metal stamping parts processing technology, molds and operation methods better realize the factory’s manual work outside the mold. For large-scale production operations, efforts can be made to reform the process and improve the mold to better realize mechanization and automation.

Install guards as much as possible. Due to the small production batch of products, safety protection devices can be installed to prevent injury accidents caused by operational errors in stamping operations that cannot be automated and cannot use safety stamping tools. All kinds of protective devices have their own different scopes and characteristics. Improper use will still cause injury accidents.

Metal stamping parts are more and more widely used, and the processing of metal stamping parts is mainly formed by processing metal sheets and forming stamping process molds. The stamping parts produced by metal stamping parts manufacturers can better have uniform, light and thin. , strong and other excellent characteristics, and its very high precision, the same specifications and so on.

Do you know what are the common mold processing methods?

1. Can use CAD mold processing method

When processing molds, a common method is the mold CAD method. When processing molds, this method generally adopts some ready-made mold standards to directly process molds. Because there are many products in design, the appearance is very similar, so in processing When making molds, for these products with small differences in appearance, some existing mold standards can be directly selected for processing and manufacturing, so that the molds can be manufactured faster. This manufacturing method is suitable for many mold processing and manufacturing, and some integrated technologies can be used when manufacturing molds.

Second, you can choose the die CAD mold processing method

When manufacturing molds by this method, it is somewhat similar to the first method, but it is improved on the basis of the previous method. When using this method to process and manufacture molds, some blanks are used, and the blanks are further optimized, so that the utilization rate of the manufactured molds is higher. When using this method to manufacture molds, due to the different requirements of each part, the methods used are also different in the stamping process. Using this method can greatly improve the utilization rate of blank materials.

3. You can choose the mold processing method of computer layout

With the continuous development of science and technology, computers play an increasingly important role in people’s lives. When people process and make molds, they can use the computer to lay out the layout and lay out several different styles through the computer. When using a computer for nesting, people can use two different nesting methods: semi-automatic and fully automatic. These two different nesting methods use different algorithms and characteristics. The entire production process can be completed more efficiently during processing.

Fourth, the stamping die processing method can be used

When manufacturing the mold, people can also use some mathematical models to describe the mold, and then use the stamping process to process and manufacture the mold. When this method is used, the precision of the manufactured mold can be higher. , the structure of each part is more perfect, and the strength of the mold can be relatively strong. By stamping the mold in an all-round way, the manufactured mold can more meet the needs of people.

There are many different mold processing methods, and people can choose different methods according to their needs for molds.

What matters should be paid attention to in the process of mold processing?

1. Precautions for precision mold processing

1. The process is concise and detailed, and the processing content is expressed numerically as much as possible.

2. For the key and difficult points of processing, the process should be particularly emphasized.

3. Combination processing is required, and the process is clearly expressed.4. When inserts need to be processed separately, pay attention to the process requirements of processing accuracy.

5. After combined processing, the insert parts that need to be processed separately shall be the benchmark requirements for separate processing of process installation during combined processing.

6. Springs are the most easily damaged in mold processing, so choose mold springs with long fatigue life.

7. High machining accuracy requirements: a pair of molds is generally composed of concave molds, punches and mold bases, and some may also be multi-piece assembled modules. Therefore, the combination of the upper and lower molds, the combination of the insert and the cavity, and the splicing between the modules all require high machining accuracy. The dimensional accuracy of precision molds often reaches μm level.

8. Complex shape and surface: For some products such as car covers, aircraft parts, toys, and household appliances, the shape of the surface is composed of a variety of curved surfaces, so the mold cavity surface is very complex. Some surfaces must be processed mathematically.

9. Small batches: The production of molds is not mass production, and in many cases only one batch is produced.

10. There are many processes: various processes such as milling, boring, drilling, reaming and tapping are always used in mold processing.

11. The use of repeated production molds has a lifespan: when the use of a pair of molds exceeds its lifespan, a new mold must be replaced, so the production of molds is often repetitive.

12. In the production of profiling molds, there are sometimes neither drawings nor data, and profiling should be performed according to the actual objects. This requires high imitation precision and no deformation.

13. Excellent mold material, high hardness The main material of the mold is mostly made of high-quality alloy steel, especially the long-life mold, which is often made of ledeburite steel such as Crl2 and CrWMn.

The above are seven aspects that need to be paid attention to in the process of precision mold processing, so that we can produce high-quality molds, and at the same time, we must meet the processing requirements as much as possible in the selection of machine tools, such as the function of the CNC system should be strong, the machine tool precision should be high, The rigidity is better, the thermal stability is better, and it has the function of profiling.

Talking about the Analysis of Precision Machining Control of Mould Parts

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.

3. Grinding of parts

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.

How to choose precision metal mold materials?

1. Meet the requirements of working conditions, such as wear resistance, alternating heat and cold, corrosion resistance, high temperature performance and toughness of materials. Generally, the higher the hardness of the mold parts, the better the wear resistance. In order to prevent the mold from breaking suddenly, the flexibility of the mold needs to be increased. During repeated heating and cooling, the mold deforms and changes the dimensions of the product to such an extent that the function of the mold is no longer effective.

2. Meet the process performance requirements. In order to ensure the quality after deep processing and finishing, and reduce the production cost, the most suitable materials should be selected in the production process to meet the technological requirements. Finally, to meet the needs of the economy, while meeting the service performance requirements, try to save costs as much as possible, and try not to use imported materials when domestic materials can be used.

The above is the editor of Zhejiang Baifudu Electromechanical to introduce the methods and methods of selecting precision metal mold materials, so everyone can use a lot in selection and use.

How much do you know about the disassembly and assembly process of progressive die and composite die?

1. Assembling molds in stamping parts processing plant

Put the mold handle into the upper mold seat for use.

Insert the punch into the fixing plate, and insert the punch loaded into the fixing plate into the female die to check whether the assembly is correct and whether the gap is uniform.

1. Assemble the die

Tighten the upper die set screws, but do not overtighten them.

Open the upper die, drive the cylindrical pin from the fixing plate to the upper die base, tighten the fastening screws, and install the stripper plate.

The mold is closed, and the entire mold-loading process is over.

Under what circumstances do you need to increase or decrease the blanking gap value when processing stamping parts?

In the process of stamping parts, under what circumstances should the blanking gap value be appropriately increased or decreased? The following Zhejiang Baifudu Electromechanical editor will take you to understand!

Under the same conditions, according to different quality requirements of parts and the production practice of stamping parts, the pressure gap can be appropriately increased compared with the blanking gap.

When punching punching parts (generally, the hole diameter is smaller than the material thickness), the punch is easy to break, and the gap should be large; but at this time, effective measures should be taken to prevent the waste from rising.

The gap of the cemented carbide punching die should be about 30% larger than that of the steel die. When the wall of the convex and concave die of the composite film is thin, in order to prevent expansion and cracking, according to different product quality requirements, the gap of the punching die should be enlarged. With the increase of the silicon content in the medium, the gap increases correspondingly, and the enlarged gap is determined by experiments.

When the elastic pressing device is used for stamping parts, the gap can be larger. According to the actual application of different elastic pressing devices, when measuring the increased gap and high-speed stamping, the mold is easy to heat up, and the gap should be increased. If the number of trips per minute exceeds 200, the gap should be increased by about 10%. When EDM the edge of the die, the effect of the metamorphic layer should be considered in the gap. When heating and punching, the gap should be reduced, and the amount of gap reduction should be measured according to the actual situation. When the concave die is an inclined-wall cutting edge, the clearance should be smaller than that of the straight-wall cutting edge. For holes that need to be tapped, the clearance should be smaller, and the amount of clearance reduction is determined by the actual situation.
