Stamping die is a special process equipment, which has the characteristics of easy operation, high production efficiency, large production batch, high material utilization rate, low processing cost, stable product quality, and good interchangeability of stamping parts. The high precision and high consistency of the parts are unmatched by any other processing methods.
Stamping dies are technology-intensive products, which have been widely used in various fields of the national economy and all walks of life. The level of design and manufacturing technology of stamping dies and plastic molds is an important indicator to measure the level of a country's manufacturing industry, and to a large extent determines the quality, efficiency and new product development capabilities of products. The following plastic mold manufacturers will describe some design skills of precision metal stamping molds:
1. Design skills: generally first trimming, punching, punching, pre-breaking, pressing, punching, tearing, punching and blanking, pressing burrs, forming, bending in two steps, forming half first, After forming the other half.
2. When punching and blanking of metal mold stamping parts, generally punch small holes first, then punch large holes: first punch the waste around the forming, and then drop the remaining materials in other parts: because if the punching holes are placed at the back, then When it is punching, there may be gaps in the corresponding parts of the material belt around the punch, so that the punch will cause uneven force during the punching process. The original small hole punch is weak, and the force is uneven. , It is very easy to break. Of course, this is only in most cases. Sometimes according to the actual situation, the small hole punch can only be placed in the back, but there are still ways. If the thickness of the punch is too small, it can be reinforced: A: Use Precise guide for stripping; B: The punch is processed by PG.
3. Determine whether to use trimming: trimming is generally used on continuous dies and blanking dies. Its function is to rough positioning and facilitate feeding during mold trial; some trimming also has the function of punching shape. Punch the positioning pinhole, and then use the guide pin to guide it immediately. Generally, there is no need to trim the edge; if there is no guide pin, the edge should be trimmed first to set the distance, which is generally used in the blanking die of the noil blank.
