Example Embodiment
[0026] The integrated process of hot forming, punching and trimming of high-strength steel parts of the present invention firstly includes corresponding trimming and punching on the punch, die or press plate of the hot forming die of high-strength steel parts. Hole tool, install edge trimming and punching device on punch, die or pressing plate. The process of this process is that the sheet material heated to austenite state is placed on the concave mold of the thermoforming mold → driven by the press, the pressing plate first presses the thermoformed sheet, and then the convex mold and the concave mold are closed , Complete the hot forming of the part → the movement of the trimming and punching device in the punch, die or blanking plate to complete the trimming and punching → pass the cooling medium into the punch, the die or the blanking plate to perform the mold Cooling to achieve quenching of high-strength parts. At the same time, the trimming and punching tools are reset, and ...
