Tooth-form deep drawing die

Abstract

The invention discloses a tooth-form deep drawing die. The tooth-form deep drawing die comprises a rolling and extruding component used for machining a workpiece; the rolling and extruding component comprises internal tooth forming assemblies and external tooth forming assemblies which are sequentially arranged in a spaced manner; the internal tooth forming assemblies and the external tooth forming assemblies each comprise at least one gear hobbing mechanism; the gear hobbing mechanisms comprise fixed plates; a plurality of rollers are circumferentially arranged on the inner side of each fixedplate; the rollers of the internal tooth forming assemblies and the rollers of the external tooth forming assemblies are alternately arranged in the axial direction; and the workpiece is machined tobe formed with internal teeth and external teeth by the rollers of the internal tooth forming assemblies and the rollers of the external tooth forming assemblies in the rolling and extruding component. By adopting the mode, the tooth-form deep drawing die can finish machining the internal teeth and the external teeth at one time, the machining procedure is simplified, the machining efficiency is improved and the machining cost is reduced.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a tooth-shaped deep drawing die. Background technique [0002] At present, most of the domestic automobile clutches depend on imports. Whether it is direct import of complete machines or imported parts assembly production, it is inseparable from the support of foreign technical forces. At present, in the processing of clutch components, the window stamping of the disc hub has always been an important process. It mainly uses punches to stamp the corresponding process hole parts. The problems of coaxiality and cylindricity in the production of clutch hubs have not been very good. The solution of the problem prevents the mass production of the clutch hub and hinders the development of the clutch. The existing processing needs to process the internal teeth first, and then trim the external teeth after the processing of the internal teeth. This is a complicated process that requires diff...

At present, in the processing of clutch components, the window stamping of the disc hub has always been an important process. It mainly uses punches to stamp the corresponding process hole parts. The problems of coaxiality and cylindricity in the production of clutch hubs have not been very good. The solution to the problem prevents the mass production of the clutch hub and hinders the development of the clutch

The existing processing needs to process the internal teeth first, and then trim the external teeth after the internal tooth processing is completed. This is a complicated process that requires different processing machines for processing. The cost is high, and it is difficult to control the processing quality.
