Production line for manufacturing automobile safety part by hot-pressing and molding high-intensity steel plate

Abstract

The invention discloses a production line for manufacturing an automobile safety part by a hot-pressing and molding high-intensity steel plate. The production line is used for manufacturing a safety part on an automobile body; and the shortcomings of low intensity, heaviness, low safety and relatively high manufacturing cost of the type of products manufactured by a steel plate cold-press process are overcome. The production line consists of a plate stacking trolley, a stack disassembly manipulator, a tunnel-type heating furnace, a high-temperature material sheet feeding manipulator, a press machine, a die, a pressurization process temperature control water cooling device, a finished product discharging manipulator and an automatic production line control system. The production line has the advantages that the automobile safety part can be manufactured by stamping the high-intensity steel plate (of which the tensile strength is more than 1,400 Mpa); the obtained product is small in thickness and high in intensity; compared with the weight of the part of the same type, the weight of the safety part can be reduced by 1 / 3; the press process is simplified; and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to production equipment for heating and pressurizing shell-shaped safety parts for automobiles with plates as raw materials. Background technique [0002] In China, existing thin-shell automotive safety components such as front and rear anti-collision beams, A-pillars, B-pillars, and door anti-collision beams are mostly cold-formed. Restricted by the manufacturing process, high-strength steel plates cannot be used as materials (generally low-strength steel plates with a tensile strength of 800-900Mpa). Considering the strength of the overall component, the thickness of the component has to be increased. On the whole, the existing cold-pressed automotive safety components have low strength, many materials, heavy weight, poor safety, and increase the weight of the car body. Moreover, the tonnage of the required press is large, the process is more complicated in the pressing proc...
