Abstract

This study delves into the methodology and implementation of reducing the dwell time in hot stamping to enhance productivity. Through the optimization of dwell time, the primary objective is to boost productivity and reduce the production cycle duration, thereby introducing a more efficient and effective production approach to the hot stamping sector. It has been observed that the non-uniform cooling of the sheet material during hot stamping results in an uneven temperature distribution within the component, consequently impacting its mechanical properties. The pivotal solution to this issue lies in enhancing the contact between the hot blank and the die to enhance the uniformity of contact pressure. By utilizing mold materials with high thermal conductivity and elevating the contact pressure, the dwell time is effectively reduced, leading to enhanced production efficiency. Furthermore, a comparative analysis is conducted between the PCH technology and the in-die spring synchronization technology as solutions. The PCH technology facilitates high-quality one-die-multipart production, maintaining elevated throughput levels and stable part quality. On the other hand, the in-die spring technology enhances the consistency of contact pressure by eliminating die-blank contact asynchrony, thereby refining the hot stamping process. This research presents a viable solution to enhance the production efficiency of hot stamping, offering significant engineering application value.
