Processing technology for plate hub of driven plate assembly and mould component adopted in the processing technology

Abstract

The invention relate to a processing technology for a plate hub of a driven plate assembly. The plate hub comprises a plate hub sheet and a plate hub core, wherein the plate hub sheet is formed by processing steel plates through material shearing, punching, leveling and thermal treatment; the plate hub core is formed by processing blank plate hub core materials through surface turning, groove lathing, gear punching and thermal refining; then the plate hub cores form an integral body through assembling and riveting treatment; after inner hole turning, shot blasting, spline broaching and rust prevention treatment, the whole processing procedure of the plate hub is completed, and the finished product plate hub is produced. A mould component adopted in the processing technology comprises a lower mould template, an upper mould and an upper mould template, wherein a lower mould universal female seat is mounted on the lower mould template; and a work lower mould is mounted in the lower mould universal female seat. For the processing technology, the machining allowance is small, the material utilization ratio is high, the verticality of the plate hub is guaranteed, the production efficiency is improved, and the performance requirement on deflection of the driven plate assembly is met, so that the torsion property is more stable. Due to the adoption of the universal female seat, the mode that specific work components are replaced is adopted, so that the use requirements of different products on the mould are met, the mould replacement time is prolonged, the number of moulds is reduced, and the manufacturing and managing costs of the mould are reduced.

Description

technical field [0001] The invention relates to a processing technology of a driven disc assembly of an automobile clutch, in particular to a processing technology of a hub of a driven disc assembly of an automobile clutch and an applied mold assembly thereof. Background technique [0002] The disc hub is an important part in the clutch driven disc assembly, which includes the disc hub plate and the disc hub core. The processing and precision of the disc hub parts directly affect the overall performance of the driven disc assembly. At present, most of the widely used monolithic disc hubs adopt die forging, that is, machining is performed after the disc hub blank is made. Therefore, its processing allowance is large, the technology is relatively backward, the material utilization rate is only about 40%, the cost is high, and the production efficiency is low; Although the company has applied the disc hub inlay technology, due to the common use of punching and stacking teeth, ...

Problems solved by technology

Therefore, its processing allowance is large, the technology is relatively backward, the material utilization rate is only about 40%, the cost is high, and the production efficiency is low; Although the company has applied the disc hub inlay technology, due to the common use of punching and stacking teeth, it is difficult to control the verticality requirements and the quality is unstable, which eventually leads to a large swing of the driven disc after assembly, which affects The whole vehicle shakes after the moving disc is installed

In terms of the application of mold components in this processing technology, as many molds as there are products, the number of molds is large, the mold change time is slow, and the manufacturing and management costs of molds are high.
