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.
In an apparatus for shaving elongate metal stock such as rod, wire or the like, a plurality of radially variable segmental die assemblies through which the metal stock is longitudinally continuously passed, said die assemblies being axially spaced along the path of the metal stock and each comprising a support therefor, diametrically opposed carriages mounted on said support for radial movement toward and away from the path of the metal stock, diametrically opposed segmental shaving dies respectively secured to said carriages for common movement therewith out of and into the path of the metal stock for removing surface metal from diametrically opposed sides of the metal stock, and reciprocating drive means for moving said carriages radially inwardly and outwardly, each segmental die assembly including adjustable mechanical stop means for limiting radially inward movement of said carriages and hence the segmental dies, said reciprocating drive means including a piston-cylinder assembly connected to each carriage for effecting radially inward and outward movement of the carriage;
In an apparatus for shaving elongate metal stock such as rod, wire or the like, a plurality of radially variable segmental die assemblies through which the metal stock is longitudinally continuously passed, said die assemblies being axially spaced along the path of the metal stock and each comprising a support therefor, diametrically opposed carriages mounted on said support for radial movement toward and away from the path of the metal stock, diametrically opposed segmental shaving dies respectively secured to said carriages for common movement therewith out of and into the path of the metal stock for removing surface metal from diametrically opposed sides of the metal stock, and reciprocating drive means for moving said carriages radially inwardly and outwardly, each segmental shaving die being formed from a block of die material which is symmetrically grooved at opposite ends thereof to provide a pair of cutting edges at each end, and each carriage including means for mounting the block at any one of a number of positions respectively presenting a different one of the cutting edges to the metal stock.
