Stamping parts processing plants, processing metal stamping parts, stainless steel stamping parts, bending parts, one of the most difficult problems in the stamping die design is the design of the inlay structure of the punch and the concave mold. The design of the inlay structure requires Only with certain design experience and practicality can we have a successful design. According to the shape and size of the convex and concave molds that are consistent with the stamping parts, the thickness of the blanking sheet and the force conditions, set the design of the inlay structure of the convex and concave molds The principles are as follows; 1. Strive to improve the processing technology, reduce the workload of fitter, and improve the processing accuracy of stamping parts mold; 2. Try to change the complex shape of the inner shape processing into the shape processing to facilitate cutting and grinding; 3 , Try to make the shape and size of the divided blocks the same. Several blocks can be processed and ground at the same time. Generally, this can be achieved by dividing along the symmetrical line; 4. Divide along the corners and sharp corners, and try to make the angle of the blocks larger than Or equal to 90 degrees; 5. The arc should be divided into pieces as much as possible. The splicing line should be cut into a straight line of 4~7mm. The large arc and the long straight line can be divided into several pieces; 6. The splicing line should be perpendicular to the cutting edge, and it is not suitable Too long, generally 12~15mm; 7. It should have a basic cross-sectional shape. For the component parts of the mosaic structure mold, the blocks or inserts should have a basic cross-sectional shape, namely square or rectangle. In order to facilitate mechanical processing, it is best to design the block so that only one block needs to be processed, and the other blocks need very little processing; article recommendation: stamping parts processing plant, talk about the advantages and disadvantages of hot stamping What are the integral die and die cutting edge?
