ROLL FORGING MACHINE AND ROLL FORGING METHOD

摘要

The roll forging machine of this invention comprises a pair of roll dies (4) and (6) that are provided on a pair of roll driving axles (3) and (5) rotated by a driver and have a plurality of shaping dies (4a1-4a4; 6a1-6a4) formed thereon respectively, and carrying units for carrying materials to be shaped to a position for shaping with the dies, to a receiving position and to a carrying out position. The carrying units comprise a first robot (10) that has a robot hand (25) moving along a first rectangular route for movement (50A) including a straight route for movement in shaping (51) connecting the positions corresponding to the shaping positions with the plurality of shaping dies and a first route for turning aside (52) spaced apart on one side by a predetermined amount (L1) from the straight route for movement in shaping (51), and a second robot (30) that has a robot hand (45) moving along a second rectangular route for movement (50B) including the straight route for movement in shaping (51) and a second route for turning aside (53) spaced apart on the other side by a predetermined amount (L2) from the straight route for movement in shaping (51). A roll forging machine and a roll forging method are obtained in which materials to be shaped are fed to a pair of roll dies with two carrying units alternately and shaping with dies is performed successively.
