Damping disk progressive die of automobile clutch

Abstract

The invention belongs to the automobile industrial field and relates to a damping disk progressive die of an automobile clutch. The damping disk progressive die of the automobile clutch comprises a locating guide head, four inclined sliding blocks forming a rectangle, inclined sliding block reset springs, bending female dies, inclined iron pieces and two flotation blocks, wherein the locating guide head is located on a progressive die body, the four inclined sliding blocks are arranged in an X shape and spread with the locating guide head as the center, each inclined sliding block reset spring is located at the tail end of the corresponding inclined sliding tail end, each bending female die is located at the root portion of the corresponding inclined sliding block, each iron piece is located between the middle section of each inclined sliding block and arranged between the corresponding inclined sliding block reset spring and the corresponding bending female die, and the two floating blocks are located on the two sides of the locating guide head. The inclined sliding block reset springs can utilize the spring force to enable the inclined sliding block and the bending female dies to conduct reset. The recovery time of the inclined sliding block reset springs is shorter than the rising time of the floatation blocks. The damping disk progressive die of the automobile clutch meets the heat treatment demand of a damping disk of the automobile clutch and meets the requirement that a continuous rotation key structure is free of cracks and fracture under the action of twisting force, the production and machining speed and the machining accuracy are improved, the punching speed and the material utilization rate are improved, and the number of needed dies is reduced.

Description

technical field [0001] The invention belongs to the field of automobile industry and relates to the processing of a progressive die, in particular to a progressive die for an automobile shock-absorbing disc. Background technique [0002] With the development of my country's automobile industry in recent years, automobile manufacturing technology has also been greatly improved. Among them, the automobile clutch is an important part of the automobile transmission system, which shoulders important functions such as power transmission, shock absorption and overload prevention. At present, most clutch parts rely on mold stamping processing, and there is a great demand for molds; at the same time, most of the molds currently used for processing, including punching dies, punching dies, and bending dies, are all special-purpose. Single-process low-end molds are inconvenient to use and time-consuming. [0003] The vibration damping disc is a key part of the automobile clutch. After...
