Optimized stamping process of DST structure cover

Abstract

The invention discloses an optimized stamping process of a DST structure cover. The optimized stamping process is characterized by comprising the following steps of: placing an SPHC (Steel Plate Hot-rolled Commercial) / SPCCA (Steel Plate Cold-rolled Commercial-A) pickling plate on a punch press, blanking to form a cover outer-edge shape and an auxiliary hole shape at intervals with a blanking and auxiliary hole-punching mold, and forming a cover shape by a forming mold on a pressure machine tool; directly trimming to form an outer circle and punching to form a middle hole shape in one step by a trimming and middle hole-punching mold on the punch press; coining each plane and a flanging hook shape of the cover by a coining and flanging mold on the pressure machine tool; and finally, punching a counterweight hole, a punch mounting hole, a pin hole and a punch drive piece hole in one step through a punching mold on the punch press. The optimized stamping process of a DST structure cover has the following beneficial effects that multiple procedures of directly forming the hook by a hook pressing slot and the like are canceled, the production efficiency is improved, the production cost is reduced, the error accumulated in multiple procedures is reduced, the dimensional accuracy of products is improved; the problems of unreasonable cover processing symmetry, unstable plastic deformation caused in the forming process, uneven parallelism, planeness and depth of the cover, poor location degrees of holes and the like are solved; the processing benchmarks of subsequent procedures are unified, the processing quality and accuracy are ensured, and the appearance quality lines are smooth, clear and attractive; and the service life of the product is greatly prolonged.

Description

technical field [0001] The invention relates to the processing of a DST structure cover, in particular to an optimized stamping process of the DST structure cover. Background technique [0002] The clutch is an important part of the car transmission system, and the clutch cover is the main part of the clutch and an indispensable part of the car clutch. The symmetry and balance of the cover have a great influence on the quality of the clutch, especially the DST structure Clutches are more demanding. At present, the DST structure cover usually adopts the process of blanking punching process hole → forming → trimming → punching center hole → pressing hook groove → fine pressing, flanging → punching counterweight hole → punching installation hole, pin hole → punching transmission After the perforation is completed, the process flow is many and single, the production efficiency is low, and the product size accuracy is not high. Contents of the invention [0003] The purpose o...
