Abstract

The invention discloses a method for manufacturing an output bracket of a clutch in an automobile gearbox. By adopting a mighty cold rotary extrusion process, a cirque sheet billet is coated on a rotary extrusion mandril and is subjected to direct cold rotary extrusion to form the output bracket of a cupped clutch. The method has the advantages of simple process steps, high yield, low cost, long service life of a finished product, and the like.

Description

technical field [0001] The invention relates to a manufacturing method of a clutch output bracket, in particular to a processing method of a clutch output bracket in an automobile gearbox. Background technique [0002] The clutch output bracket commonly used at present, the traditional processing method is to heat-treat the blank first, then forge or stamp the blank into a bowl shape, and finally complete the high-precision internal splines of the clutch bracket by machining technology. This kind of processing method has a long, time-consuming and complicated process, and cannot process splines without undercuts; the production cost is high, and it cannot meet the mass production of parts. [0003] Therefore, it is an urgent technical problem for those skilled in the art to design a low production cost, simple and efficient method for processing the clutch output bracket. Contents of the invention [0004] The technical problem to be solved by the present invention is to ...
