Optional processing process of clutch driven disc

Abstract

The invention discloses an optional processing process of a clutch driven disc. The process is that shapes of the outside, a central hole, a phi10 hole and a phi 12 hole of the driven disc are punched by raw materials on a punch through dies for blanking and punching the central hole, the phi 10 hole and the phi 12 hole in a gap mode; then shapes of a phi 6.2 hole, a phi 5.2 hole and a spacing hole of the driven disc are punched on a pressure machine tool through dies of the phi 6.2 hole, the phi 5.2 hole and the spacing hole; and finally shapes of a window and a long U-shaped groove are directly formed on the punch through dies for punching the window and the groove for once. The optional processing process of the clutch driven disc has the advantages of canceling heat treatment and leveling, solving an extremely bad flatness problem, being environment-friendly as well as energy-saving and cost-reducing, improving work efficiency, reducing cost and errors accumulated in a plurality of processes, and improving product size procession. Subsequent processes are uniform in processing standards, processing quality and precision are guaranteed, service life of a driven disc assembly is greatly prolonged, and performance of the driven disc assembly is greatly improved.

Description

technical field [0001] The invention relates to the processing of a clutch driven plate, in particular to an optimized processing technology of the clutch driven plate. Background technique [0002] The driven plate is an important part of the automobile transmission system, and the clutch driven plate is the main part of the driven plate and an indispensable part of the automobile clutch. The clutch driven plate plays a role in connecting the driven plate, toggling the vibration damping spring, etc. Function; At present, the production process commonly used in the clutch follower in the industry is: cutting 65Mn steel plate → blanking → punching the middle hole → punching φ10 hole and φ12 hole → punching φ6.2 hole system and φ5.2 hole system → It is made by punching limit hole → punching window → single punching → heat treatment and leveling. This kind of production process has many processes, and the thickness of the material is only 2-2.5 mm, and it is elastic, so the de...

AI Technical Summary

Problems solved by technology

This kind of production process has many processes, and the thickness of the material is only 2-2.5 mm, and it is elastic, so the deformation is large during the processing, and the flatness of the parts reaches 1-2 mm. It needs heat treatment and leveling to achieve the precision required by the product. Production low efficiency
