抄録

A flexible forging method for production of disk-shaped product in which the billet is successively compressed by a pair of upper dies is proposed. The distance between the upper dies, the ram stroke and the angle of rotation of lower die are controlled by a microcomputer. To examine the problems associated with this method, disk-shaped billets of plasticine are compressed on a small-size flexible machine. It is observed that flaws appear on the compressed surface of the product and nonuniform deformation results over the circumferential surface of product. A sound product without large flaws is obtained when disks are repeatedly compressed with a small reduction in height by dies having a round corner, the radius of which is greater than the reduction in height. The nonuniform deformation over the circumferential surface is effectively reduced by employing a large rotation angle after each compression.
