Abstract
A production line sequentially includes a feeding platform, a feeding robot, a pressing unit, a conveying robot, a quenching device, a discharging robot, and a conveyor belt. The pressing unit includes a heating device, a die device, and at least one press used for mounting the die device. The heating device is used for wholly or partially heating the preformed blank to produce a hot blank, and the die device is used for stamping the hot blank, holding the hot blank at a certain pressure, and shaving and punching the hot blank, so as to produce a hot stamped part. The production line can continuously achieve rapid heating, stamping, pressure holding, shaving, punching, and quenching. Heating efficiency is improved, and a transferring process before stamping the hot blank is avoided.
