Abstract:
A production process for stamped parts carried out from bales of sheets (1), a first moving robot (2), a heating device (3) with a liquid cooling unit (4), a second moving robot (4), a hydraulic press (5) with a specific molding tool, a third moving robot (6), and a conveyor belt (8), controlled by an electronic control unit. Said specific molding tool is provided with channels for cooling done through heat exchange, via water circulation, where the cooling rate is controlled by means of the liquid's flow and temperature control.
