Abstract:
1. A heading device for an elongate workpiece, comprising: a hydraulically actuated chucking unit comprising a housing having a sliding body which is hydraulically displaceable in an axial direction between a starting position and a clamping position, at least two chucking segments inserted within the sliding body, and a locking plate having an opening inserted within the housing and removeably fixed therein, wherein the at least two chucking segments are movable in a radial direction between an open position and a clamped position with the axial displacement of the sliding body toward the clamping position radially moving the at least two chucking segments toward the clamped position and the axial displacement of the sliding body toward the starting position moving the at least two chucking segments toward the open position, and each of the at least two chucking segments receiving at least one clamping jaw for holding the at least two chucking segments radially against the workpiece in the clamped position; and a shaping ram carrying a forming tool moveable in the axial direction between a retracted idle position and an extended compression position, wherein the shaping ram carrying the forming tool is moveable completely out of the opening in the locking plate when in the retracted idle position, and the shaping ram carrying the forming tool extending through the opening in the locking plate when in the extended compression position, and wherein the forming tool is capable of shaping a forward end of the workpiece protruding axially from the clamping jaws by compressing the forward end when moved to the extended compression position.
