Abstract
An apparatus and method for shaving elongate metal stock such as rod, wire and the like, characterized by the employment of a plurality of progressive die stations each including diametrically opposed segmental dies which are automatically indexed to remove surface imperfections from metal stock, to impart desired cross-sectional shapes to the metal stock and/or to impart desired tapered profiles to the metal stock. The segmental dies at each station are rigidly secured to respective carriages by heel and toe clamps and the carriages are radially advanced and retracted in rigid restraints by hydraulic actuators provided with adjustable mechanical stops which limit inward carriage adavancement. The carriages and hydraulic actuators for each station are mounted on a mounting plate which is securable to an upright support plate at any one of a member of rotated positions. The support plates are fixed at their lower ends to a base structure and tied at their upper ends to adjacent support plates as well as the base structure to eliminate or minimize chatter as the metal stock is continuously advanced through the progressive die stations.
