Description

technical field

[0001] The invention belongs to the stamping technical field of automobile structural parts, and relates to a cold stamping die structure in the field, more specifically, the invention relates to a forming die for processing high-tensile plate parts. Background technique

[0002] At present, in order to reduce automobile exhaust emissions and improve the collision safety performance of automobiles, automobile design strives to reduce the weight of various parts of automobiles as much as possible while ensuring automobile safety. In view of this, the use of high-tensile materials will become the trend of automotive materials.

[0003] According to the international research on ultra-light steel automobiles (ULSAB-AVC), steel plates with a yield strength in the range of 210-550N / mm2 are called high-strength steel plates, that is, high-tensile materials; steel plates with a yield strength greater than 550N / mm2 are called Ultra-high strength steel plate.
