摘要:
The invention relates to a method for producing without cutting a gear part having a hub. According to said method, to form the hub a front end of the workpiece made of a steel sheet billet is joined to an additional main spindle (22) and held in position by an additional movable stop (55) having a receiving recess. By pressing the workpiece by means of one or more pressure rollers (66), the thickness of the back of said workpiece is reduced and deformed into a stepped body inside the receiving recess (3) of the movable stop, said stepped body being configured concentrically to form a hub. After the hub has been formed, the front end of the workpiece produced from a steel sheet billet or pre-drawn part is joined to a further main spindle and held in position by an additional movable stop (55) having a receiving recess. By pressing the workpiece by means of one or more pressure rollers (66), the thickness of the back of the workpiece is reduced and deformed into a stepped body inside the receiving recess of the movable stop, said stepped body being configured concentrically to form a hub.
