Preliminary forming apparatus for complex forging processes

摘要

In the preforming of composite forging, by automating the fixing and positioning of the metal material during the circularization, upsetting, rear extrusion and piercing process of the metal material, it is possible to reduce the defect rate and improve the work efficiency, thereby reducing cost and productivity. Disclosed is a preforming apparatus 100 for composite forging that can improve. On the upper surface of the bed frame 110, which is the lower structure of the preforming apparatus 100 for composite forging, a preform block 150 for accommodating a heated metal material is arranged to be movable in the horizontal direction, and the bed frame ( In order for the slider frame 120 interposed between 110 and the crown frame 130 as the upper structure to approach or move away from the preform block 150, the crown frame 130 has a main cylinder 160 and a plurality of A kicker cylinder 170 is disposed, and the second transfer block 180 mounted to be movable in the horizontal direction on the lower surface of the slider frame 120 is moved in the horizontal direction by a separate servo motor. Possibly, on the lower surface of the second transfer block 180, a plurality of pressure rods 190 for preforming by pressing the heated metal material are integrally fixedly arranged to extend downward.
