Forging unit for gear wheels - has blank forged in toothed stamping die by longitudinal introduction of at least one press

摘要

The process is for forging gear wheels, It uses a blank (24) which is forged in a stamping die (18) by longitudinally introducing at least one press ram (20) with external inclined engraved teeth (21) and is thereby expanded expanded radially into the internal inclined engraved teeth (19) of the stamping die (18). Relative rotation between the press ram (20) and stamping die (18) is effected during insertion of the die (18) which corresponds to the insertion speed and the inclination of the engraved teeth. A cam gear (26) effects relative rotation between the press ram (20) and stamping die (18) in relation to the axial ram path in such a way that the engraved teeth screw-fir in one another. The ram (20) or stamping die (18) are rotatably supported on the ram (11) or press table (10) by an axial pressure bearing (14) and a radial bearing (15). USE/ADVANTAGE - The system permits the production of gears with inclined teeth.
