Why does waste move up during the processing of stamping parts

The upward movement of waste refers to the phenomenon that the waste in the mold gathers together with the rise of the punch during the stamping process of the metal stamping parts, and then falls into the mold. The upward movement of scrap is a very common problem in the stamping process, but metal stamping parts processing plants need to pay special attention, because it is likely to cause production accidents. Next, based on decades of experience in stamping processing, Precision has summarized some of the reasons for the upward movement of waste during the processing of stamping parts. I hope everyone can gain something. 1. When the gap is too large, the waste of stamping parts is easy to move upward; 2. If the straight wall of the mold is polished or polished, it will cause the waste to move upwards because it is too smooth; 3. The straight wall of the mold is too high and clogged, stamping The waste material of the piece is easy to move upward; 4. When it hits the back of the die and blocks the waste material, the waste material is easy to move upward; 5. Compared with the thickness of the plate, the shape of the blanking waste material is large and thin, and it is firmly absorbed by the punch . 6. Adhesion due to the use of high-viscosity lubricants; 7. After grinding the concave mold, the cutting edge is too sharp; 8. The position and function of the unloading plate are not suitable 9. Magnetic adsorption; 10. The number of times the male mold is inserted into the female mold Too little; [Related recommendation] Learn more: What are the methods for polishing the surface of stainless steel?
