Problems solved by technology

Most of the hot stamping dies in the prior art are as figure 1 As shown, the punch and die (or with cooling channels) made of fast heat dissipation materials are directly in contact with the steel plate. During the hot stamping process of the heated steel plate, the process of forming and quenching hardening is completed at the same time. However, using the abo...

Abstract

The invention discloses a steel plate electromagnetic hot stamping production line and a hot stamping forming method thereof. The steel plate electromagnetic hot stamping production line mainly comprises a blanking station, a laser heating station and a hot stamping and quenching station. The hot stamping and quenching station comprises a hot stamping press machine, a control system of the hot stamping press machine, and a hot stamping mould. The hot stamping mould comprises an upper mould and a lower mould which are provided with cooling channels. An electromagnetic forming component is arranged at the bent portion of one of the upper mould and the lower mould. The hot stamping forming method comprises the steps that blanking, heating, transfer, stamping and quenching and subsequent processing are conducted, after a formed part is taken out of the mould, oxide skin on the surface of the formed part is removed in an acid pickling or shot blasting mode, and the formed part is subjected to laser trimming and laser perforation.

Description

technical field [0001] The invention relates to a stamping production line and a stamping forming method of a metal plate, in particular to an electromagnetic hot stamping production line of a steel plate and a hot stamping forming method thereof. Background technique [0002] Due to the high mechanical strength of the high-strength steel plate, under the same conditions, reducing the thickness of the steel plate can meet its strength requirements, or the position where two parts were originally required, now one part can meet the strength requirements, thereby improving High-strength steel stampings can effectively reduce the weight of the car body and ensure the safety performance of the car. But at the same time, the high strength has created new problems for automakers. With the increase of yield strength and tensile strength of high-strength steel plate, its hardening index n value and anisotropy index r value decrease, the stamping performance decreases, and various f...
