Laboratory trials and design of industrial application of hot stamping of 22MnB5 tailored components by partition heating

摘要

Hot stamping of 22MnB5 by partition heating may represent an effective method to produce tailored parts of the car body-in-white to improve collision performances. This paper investigated its feasibility and applicability at both laboratory and industrial level. First, an M-shaped part was stamped using a specially-designed partition heating device, and its finite element model established and validated. Secondly, a partition heating device suitable for industry was designed for stamping tailored B-pillars. The hot stamping by partition heating to produce B-pillars was simulated, analysing major characteristics during and after stamping and quenching.
