This patent adopts a feeding system, an extrusion system, and a discharging system. The feeding system includes a guide rack, a hot melt furnace, a discharge box, and a material placement trolley. The middle of the top surface of the guide rack is provided with a guide trolley for horizontal movement by opening a guide rail. The surface of the hot melt furnace away from the guide rack is provided with a hot cutting knife for vertical movement by a screw rod. The extrusion system includes a hydraulic extruder, a forming template, and a slitting machine. A limit plate is provided on the surface of the support rod between the forming template and the hydraulic extruder. The discharging system includes a traction trolley, a material moving rack, and a discharging trolley. When the invention is used, the hot melt furnace can effectively change the state of the aluminum material to facilitate the subsequent fixed-distance cutting operation. The forming template is connected to the hydraulic shaft at one end of the hydraulic extruder under the action of the limit plate, which can quickly and stably complete the extrusion forming operation of the plate, and has high work efficiency.
