How to solve the problem of unqualified stamping size of electric vehicle stamping parts

1. In the production process of electric vehicle stamping parts, due to the burrs of the stamping parts during blanking, it is necessary to study the cutting edge, and it is also necessary to pay attention to whether the blanking gap is reasonable. During bending, the instability of stamping parts is caused, mainly for U-shaped and V-shaped bending, for the guide position before bending, the guide position during the bending process, and the pressure during the bending process. Holding the material to prevent the stamping from slipping during bending is the key to solving the problem.

2. During production, the stress on the material increases, and the stamping parts tend to turn over and twist. When the material is turned over, the size of the punching hole will become smaller, and the strong pressure on the material will cause plastic deformation of the material, so the size of the punching hole will be larger. Thereby reducing the strong pressure, the punching size will be smaller.

3. In the production process of electric vehicle stamping parts, if the end is repaired with a slope or arc, due to the relief of the punching force, the stamping parts are easy to turn over and slander, so the stamping size will be larger. The convex end is flat, and the size of the punching hole is relatively small.
