In a heading device for elongate workpieces having a hydraulic chucking unit and an shaping ram, which is movable axially from a retracted idle position against the workpiece, the chucking unit comprises a housing having a sliding body which is hydraulically displaceable in the axial direction of the workpiece from a starting position into a clamping position (and vice versa), in which at least two chucking segments which are situated uniformly around the workpiece are inserted, which, on their side facing toward the shaping ram, press against a locking plate which is inserted into the housing and can be fixed therein, are movable radially against the workpiece by a displacement of the sliding body in its clamping position, and each receive at least one clamping jaw, which can be pressed by the chucking segment holding it radially against the workpiece for its clamping. The shaping ram carries a forming tool for upsetting the workpiece on the extension side, using which it can be pressed against the head of the workpiece protruding axially from the clamping jaws upon extension through an opening provided in the locking plate, and is moved completely out of the opening in the locking plate with its forming tool in its retracted idle position.
A heading device for elongate workpieces, such as bars, pipes, wires, or the like, comprising a hydraulically actuated chucking unit and a shaping ram, the shaping ram movable axially from a retracted idle position toward the workpiece, the chucking unit comprising a housing having a sliding body which is hydraulically displaceable in the axial direction of the workpiece from a starting position into a clamping position (and vice versa), in which at least two chucking segments, which are situated uniformly around the workpiece, are inserted, which, on their side facing toward the upsetting ram, press against a locking plate, which is inserted into the housing and can be fixed therein, are movable radially against the workpiece by a displacement of the sliding body toward its clamping position, and each chucking segment receiving at least one clamping jaw, for holding the at least two chucking segments radially against the workpiece thereby clamping said workpiece, furthermore, the ram also carrying a forming tool for shaping the workpiece by compressing the forward end of the workpiece that is protruding axially from the clamping jaws by extending the ram through an opening provided in the locking plate, the ram moveable completely out of the opening in the locking plate with its forming tool when in its retracted idle position.
A heading device for elongate workpieces, such as bars, pipes, wires, or the like, the heading device having a central axis and comprising:
A method of changing out chucking segments of a heading device for elongate workpieces, such as bars, pipes, wires, or the like, the heading device having a central axis and comprising:
