Automobile clutch damping disk forming lower die

Abstract

The invention discloses an automobile clutch damping disk forming lower die which comprises a lower prepressing plate, a punch-retainer plate, a spring, a forming punch, a lower bolster, a lower die base and an inner guiding post; the forming punch is fixed on the punch-retainer plate and is fixed on the lower bolster through a hanging table; the spring is arranged in a through hole which is formed between the punch-retainer plate and the lower bolster; the punch-retainer plate is locked with the lower bolster and the lower die base; the inner guiding post is fixed on the punch-retainer plate to limit the relative position of the lower prepressing plate, and the lower prepressing plate can move up and down along the inner guiding post through the spring; and when the forming punch is adjusted, the lower prepressing plate is taken out, and the forming punch can be dismounted to adjust the forming depth size of a window the damping disk. With adoption of the technical scheme of the automobile clutch damping disk forming lower die provided by the invention, fast install and uninstall of the forming punch of the automobile clutch damping disk can be rapidly realized, the dismounting time is shortened, the working efficiency is greatly improved and the manpower cost is reduced.

Description

technical field

[0001] The invention relates to the field of auto parts processing, in particular to a lower mold for forming an automobile clutch damping disc, which includes a lower preloading plate, a punch fixing plate, a spring, a forming punch, a lower backing plate, a lower mold base, and an inner guide column. Background technique

[0002] Due to the high requirement of depth accuracy for the forming mold of automobile clutch damping disc, the height of the punch often needs to be adjusted during the mold trial process and production to meet the depth requirement. Since the working surface of the punch cannot be imprinted, the structure screws of the original punch are even Lock from bottom to top, and the mold is clamped on the machine tool. Every time the mold is adjusted, the entire lower mold needs to be removed from the machine tool, and then the mold is turned over to remove the punch. After adjustment, it is installed on the machine tool , if the debugging is ...
