ABSTRACT:
Apparatus for the continuous shearing off and cold swaging of metal workpieces, particularly wire material, comprises a device (1') for feeding the material (5), a pivotable shearing device (2), a slide (1) for swaging the sheared-off part, and a die-studded chuck (31). These components are arranged so that they are distributed in the machine frame (11) along the sides of a U. These components can all be driven by a motor (4) via a conventional drive. Feeding of the material (5) in the direction of the chuck (31) takes place with intermittent motion and in synchronism with the movements of the described components of the machine. The production output of finished parts is greatly increased by the chosen arrangement, the intermittent feeding of the material, and the pivotability of the cutter. The slide has a holder (37) for a plurality of tools in sockets (43, 44, 45 or 43', 45'). These sockets, and the axis of the material, lie on an imaginary circle that is of the same diameter as and coaxial with an imaginary circle on which the dies (30) on the chuck lie. Each of those sockets, and the material, is aligned with a respective one of the dies in every stopped position of the chuck, so that a tool held by the slide will strike a shorn-off workpiece every stroke of the slide.
