DEVICE FOR SCALPING BILLETS Russian patent published in 1994 - IPC

FIELD: metal pressure working. SUBSTANCE: device includes load-bearing frame formed by forward and back fixed cross bars connected each to another by columns; movable cross bar connected to plungers of working and reverse cylinders; scalping die; centering devices for forward and back billet ends; and waste removal device. The device is provided with a processed billet pushing-out mechanism made as a beam placed over scalping axis on the exit section of the forward fixed cross bar. The guides of the beam support a traveling slide bearing a rotor ring with mounted stop member movable along the vertical axis. The back end centering device is made in the shape of a bushing having internal stepped borings of different diameters which mate with conical generatrix surfaces, and is installed for reciprocating displacements in the forward fixed cross bar guides. The waste removal device is located on the forward fixed cross bar side surface outside the billet deformable zone and is made in the form of a movable beam secured on an actuating cylinder rod and interacting with two spring- actuated movable rings rigidly connected each to another. One ring envelops scalping die fixed in the tool board. EFFECT: enlarged operating capabilities. 5 dwg
