1. Blanking: It is a process in hot stamping forming, punching out the required outer contour blank of the plate.
2. Austenitization: includes two stages of heating and holding. The goal of this process is to heat the steel plate to a suitable temperature, so that the steel plate is completely austenitized and has good plasticity.
3. Transfer: refers to taking the heated steel plate out of the heating furnace and putting it into the hot forming mold. In this process, it is necessary to ensure that the steel plate is transferred to the mold as quickly as possible. On the other hand, it is to avoid oxidation of the steel plate under high temperature, and at the same time, to ensure that the steel plate is still at a relatively high temperature during forming. Below, there is good plasticity in this way.
4. Stamping and quenching: After the steel plate is put into the mold, the steel plate should be stamped and formed immediately to prevent the temperature drop from affecting the forming function of the steel plate. After molding, the mold must be closed and held for a period of time. On the other hand, it is used to control the shape of the whole machine. At the same time, the steel plate is quenched by the cooling installation set in the mold, so that the whole machine has a uniform martensitic structure. , To achieve good dimensional accuracy and mechanical performance.
