Why does the punch of the stamping die break?

With the development of society, the application of stamping parts has become more and more extensive. The role of stamping dies in the production of stamping parts is very important, which directly determines the size and accuracy of the stamping parts. In the production process of stamping parts, the stamping factory will find that the punch of the stamping die will break, so how to solve it, the author of precision will tell you. 1. The strength of the punch in the stamping die is too high, and the punch materials are not equal. For such problems, the punch materials must be replaced immediately to adjust the strength. 2. The fixed position and guiding position of the punch in the stamping die are offset. For this kind of problem, it is necessary to repair the electromechanical or cut into the block again to make the punch left and right smoothly. 3. The punches in the stamping die are not very well fixed, and they shake left and right, and the punches must be fixed again to prevent them from shaking left and right. 4. The cutting edge of the punch is not sharp; grinding the cutting edge again; 5. The closing height is too low, and the selected wound part of the punch in the stamping mold is too long; 6. The upper mold waste blocks the wound and causes the punch to rupture, for this type of , Drill a large blanking hole again to make the blanking smooth; 7. The height of the folding knife is insufficient, and the folding punch is too short to be inserted into the folding knife; 8. The structure is unscientific, and the folding knife is not embedded in a fixed template; 9. The bending rate is too fast, resulting in deformation at the bending root of the punch; [Recommended recommendation] Learn more: Precautions for designing a continuous stamping die (2) Learn more: 6 precautions for designing a continuous stamping die Learn more: stamping die Analysis of the cause of burst
