Method and apparatus for the chipless axially metal-forming formation of a toothing with integrally formed tips on a workpiece

摘要

Device for the chipless axially metal-forming formation of a toothing (2) with integrally formed tips (12) on a workpiece (3) and, in particular, on a shaft, with a in a clamping ring (16) clamped first die (10), by means of which the toothing (2) is formed, for which purpose the first die (10) an inside recess (8) and a on the inside recess (8) and forming a first toothed profile (31), characterized in that a with an axial distance from the first die (10) and arranged in the clamping ring (16) clamped second die (11) is provided, by means of which on the tooth system (2) the integrally formed tips (12) are formed, for which purpose the second die (11) a at a distance from the shaping first toothed profile (31) and forming a second toothed profile (14) provided at a from the first toothed profile (31) spaced region of lateral flanks (46) with a tapering distance, which is attached to the workpiece (3) designed lateral tooth flanks (47) of tapered shaping.
