What are the technological properties of precision stamping die production materials? 'hardware'

Precision stamping dies are important equipment required for stamping processing, 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 Mold making materials should have the following process performance introduction. 1. Forgeability: It has low hot forging deformation resistance, good plasticity for precision stamping parts, wide forging temperature range, low forging cold cracking and low tendency to precipitate network carbides. 2. Machinability: Large cutting consumption, low tool loss and low surface roughness. 3. Annealing processability: Wide spheroidizing annealing temperature range, low annealing hardness and small fluctuation range, high spheroidizing rate. 4. Hardenability: uniform and high surface hardness after quenching. 5. Hardenability: After quenching, a deeper hardened layer can be obtained, and it can be hardened by using mild quenching medium. 6. Grindability: The relative wear of the grinding wheel is small, the limit grinding amount is large, it is not sensitive to the quality of the grinding wheel and the cooling conditions, and there is no abrasion and cracks in the grinding precision stamping die. 7. Sensitivity to oxidation and decarburization: When heated at high temperature, it has good oxidation resistance, slow decarburization speed, insensitive to heating medium, and little tendency to produce pitting. The manufacture of precision stamping dies generally requires several processes such as forging, cutting, and heat treatment. The processing is difficult and requires high manufacturing materials. It should have good processing performance to ensure that no craftsmanship occurs in the manufacturing process of precision stamping dies. Defects and stable quality.
