Problems easily occurred in drawing process of stamping parts

Due to the different shapes and sizes of products in the process of stamping, different stamping processes are required, and deep drawing is one of them. In the actual production of deep drawing, some problems are easy to occur, which affect the product quality and processing efficiency. Please refer to the following points for specific problems.

1. The wear of the die will cause the inner diameter of the stretching piece to be too large
2. Excessive jacking force will cause larger inner diameter; Insufficient will cause the inner diameter of the stretching piece to be smaller
3. The inner diameter of the stretching piece will be larger if the stretching material is too thin; Too thick will lead to smaller inner diameter
4. Too high temperature or oil leakage of the hydraulic oil used for deep drawing will cause the inner diameter of the stretching piece to be too small
5. The mouth of the stretch piece is easy to wrinkle
6. The stretching piece is strained
7. There are gouges and bruises on the appearance of the stretching piece
