What are the preparations before the metal stamping process design?

Stamping processing plants, processing machinery metal stamping parts, stainless steel stamping parts, and metal stamping process design should be carried out on the basis of collecting, investigating, and mastering the original data about the design, so as to be targeted and avoid blindness in work; 1 , First understand the part drawings and technical requirements. Part drawings are the basis for the design of the hardware stamping process. The part drawings should have complete views, clear and no omissions in dimensions, etc., and comply with the national drawing standards. The technical requirements should be clear and reasonable; this way We can have a full understanding of the structure, shape, size and accuracy of the metal stamping parts, as well as the assembly relationship; in order to formulate the process plan, select the mold type and determine the mold accuracy; 2. To understand the size and performance of the raw materials , Process and other conditions; the selection of raw materials for metal stamping has a direct impact on process design. For example, whether it is sheet material or strip material, whether it is coil material or waste material utilization, etc., the process plan developed is also different; for example, if a metal stamping part is stretched, if the sheet material used has a smaller yield ratio, it is more A large plate thickness anisotropy coefficient is easier to stretch. On the contrary, if a plate with high hardness, large yield strength, and a small plate thickness anisotropy coefficient is used, it is difficult to stretch; 3. Stamping products The production batch and the degree of finalization of the product. The production batch and the degree of finalization of the product are important content that must be considered in the process design. The production of any product has the problem of production volume and the degree of finalization. Before the process design, you should understand the metal stamping parts Whether the product is trial production, small quantity or mass production, determine the processing method and select the mold type; whether to use stamping method processing or other method processing, whether to use simple mold structure or more complex mold structure; 4. Stamping processing plant should be considered Existing stamping equipment models and specifications should take into account the existing stamping equipment in the stamping processing plant. It is not only an important basis for selecting equipment in mold design, but also has a direct impact on the formulation of process plans; to put it bluntly, it is different stamping equipment conditions. Correspondingly, there are different process plans and mold structures; 5. The manufacturing conditions and technical level of stamping molds. The existing mold manufacturing conditions and technical levels of stamping processing plants have a direct impact on process design and mold design. Consider the stamping manufacturer’s mold making capabilities and customary processing methods to provide a feasible basis for formulating process plans and mold structural design; if the factory’s mold making capabilities are poor, it is not advisable to use composite stamping or continuous stamping process plans to avoid composite The manufacture of die or progressive die fails to meet the design requirements; 6. Other technical materials include stamping manuals, die design manuals, die drawings, cold stamping die national standards, ministerial standards, corporate standards, mechanical design manuals, material manuals, etc. Technical reference materials, etc., to help designers carry out design calculations, select materials reasonably and master dimensional accuracy, etc., so it can simplify the design process, shorten the design cycle, and improve design efficiency; article recommendation: performance and characteristics of aluminum stamping parts One: Hardware stamping parts-the application and characteristics of the spring sheet
