What are the technological properties that precision automotive stamping molds should have?

Precision stamping dies are important equipment for stamping fabrication, which is related to the quality of precision stamping parts. Therefore, there are high requirements for the manufacture of precision stamping dies. In order to ensure the manufacturing quality of precision stamping dies and reduce production costs, precision stamping The mold making material should have the following technological properties:

1. Forgeability:

It has low hot forging deformation resistance, good plasticity of precision stamping parts, wide forging temperature range, low tendency for forging cold cracking and precipitation of network carbides.

2. Machinability:

The cutting amount is large, the tool loss is low, and the machined surface roughness is low.

3. Annealing technology:

The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.

4. Hardenability:

It has a uniform and high surface hardness after quenching.

5. Hardenability:

After quenching, a deep hardened layer can be obtained, which can be hardened by using a mild quenching medium.

6. Grindability:

The relative loss of the grinding wheel is small, the limit grinding consumption without burns is large, and it is not sensitive to the quality of the grinding wheel and cooling conditions, and does not cause abrasion and cracks in the grinding precision stamping die.

7. Oxidation and decarburization sensitivity:

When heated at high temperature, it has good oxidation resistance, slow decarburization, insensitivity to heating medium, and small tendency to pitting. The manufacture of precision stamping dies generally has to go through several processes such as forging, cutting, heat treatment, etc. The fabrication is difficult, and the requirements for manufacturing materials are high. Auto parts should have good fabrication performance to ensure the precision stamping dies in the manufacturing process. There are no process defects, and the quality is stable.
