Hot stamping deep drawing mold of ultrahigh-strength steel box-shaped part

Abstract

The invention relates to a hot stamping deep drawing mold of an ultrahigh-strength steel box-shaped part, and belongs to the technical field of hot stamping forming equipment. The box-shaped part can serve as a research object; on the basis of combining an external press with a servo ejector rod system, such deep drawing forming performances as blank holder force and stamping speed of ultrahigh-strength boron manganese steel under different forming process parameters are researched; a blocking structure is adopted to uniformly distribute cooling water ways in a mold convex mold, a concave mold, a blank holder and a movable cushion block; and on the basis of combining with an external cooling water flowing speed control system, the influence on overall performances of the final box-shaped part by different quenching control processes can be researched.

Description

technical field

[0001] The invention relates to a hot stamping deep drawing die for an ultra-high-strength steel box-shaped part, which belongs to the field of hot stamping forming equipment and technology. Background technique

[0002] In the face of the increasingly serious energy crisis and environmental pollution, the automobile industry, which is the main source of energy consumption and exhaust emissions, has become an urgent need for energy conservation and emission reduction. Body lightweight technology is an effective solution proposed by the automobile manufacturing industry in response to "energy saving and emission reduction" measures, that is, the use of relatively high-strength materials, such as aluminum alloys, magnesium alloys, ultra-high-strength steel, etc., with less material Reach or exceed the original structural strength, so as to achieve the purpose of reducing the quality of the vehicle. Since ultra-high-strength steel is added with trace total elem...
