Start the hydraulic cylinder 12 to stretch and drive the pressure head 14 to move toward the pressing groove 16. The raw material in the pressing groove 16 is forged and formed, and then the formed raw material is taken out from the pressing groove 16.

When the hydraulic cylinder 12 contracts and drives the upper mold 13 and the pressure head 14 to reset, the cylinder 4 is started to stretch and drive the baffle 41 to move to the bottom of the upper mold 13. When the top of the baffle 41 contacts the bottom of the upper mold 13, it will support it from the bottom of the upper mold 13. When the linear motor 19 drives the connecting plate 110 to move, the connecting plate 110 will drive the slider 114 to slide on the slide bar 113.
