What are the precautions in the design of drawing die?

1. The stretching material of the stretching die.

If the repeated test model does not meet the requirements, the material with good tensile properties can be replaced. Where there is quality, there is success. The commonly used specification is 08 steel, which is divided into boiling steel and stable steel. The price of boiling steel is low, the surface quality is good, but the angle is serious, it has a tendency of strain aging, and the appearance requirements are high.

Second, the surface finish of the drawing die.

In deep drawing, especially stainless steel plate and aluminum plate are easy to produce drawing when deep drawing, and tensile fracture is serious.
