Abstract

The invention relates to an adjustable heating and cooling integrated hot forming die, and belongs to the technical field of high-intensity steel plate material punching hot forming. The invention aims to overcome the defects in the prior art and provide an adjustable heating and cooling integrated hot forming die which can enable the heating, punching and forming and cooling of a plate material to be completed in the same die, moreover, because a concave die movable base plate can be adjusted, punching pieces with different depths can be obtained through hot forming.

Description

technical field [0001] The invention relates to an adjustable heating and cooling integrated thermoforming die, which belongs to the technical field of stamping thermoforming of high-strength steel sheets. Background technique [0002] Safety, environmental protection, and energy saving have become the themes of current automotive technology development. The use of high-strength steel stamping parts to manufacture the body not only reduces the weight of the car body, but also improves the safety of the car. However, due to the high yield strength, tensile strength and low elongation of high-strength steel sheets, conventional cold stamping is difficult. Hot forming technology is an advanced manufacturing technology specially used to form high-strength stamping parts, which can solve the limitations of high-strength steel plate formability. [0003] The principle of hot forming technology is to send the blanked high-strength steel plate into the heating device and heat it to...
