Abstract

The invention relates to the technical field of automobile plate spring production, in particular to a plate spring end portion chamfering and edge extruding composite die. The plate spring end portion chamfering and edge extruding composite die comprises an upper die plate and a lower die plate. The upper die plate is provided with an upper chamfering cutter and an upper edge extruding block. The lower die plate is provided with a lower chamfering cutter and a lower edge extruding block, wherein the lower chamfering cutter corresponds to the upper chamfering cutter, and the lower edge extruding block corresponds to the upper edge extruding block. The lower chamfering cutter is fixed to a lower chamfering cutter base. One end of the lower die plate is provided with a chamfering limiting mechanism corresponding to the lower chamfering cutter base, and the other end of the lower die plate is provided with an edge extruding limiting mechanism corresponding to the lower edge extruding block. The plate spring end portion chamfering and edge extruding composite die is compact in structure and can carry out chamfering and edge extruding on the end portion of a plate spring, the work efficiency is improved, and the manual labor intensity is lowered; and energy is saved, the width of the plate spring subjected to edge extruding is guaranteed, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of production of automobile leaf springs, in particular to a compound mold for cutting corners and extruding edges at the ends of leaf springs. Background technique [0002] The leaf spring needs to be corner-cut during the processing process. After corner-cutting, the end of the leaf spring needs to undergo secondary processing until it reaches the required width before meeting the factory regulations. Because the material of the leaf spring is very hard, no matter whether it is chamfering or processing the width of the end of the leaf spring after chamfering, heating is required. In the existing leaf spring production process, firstly, the end of the leaf spring is heated, and then the end of the leaf spring is chamfered by a corner cutting station; after the corner cutting is completed, the end of the leaf spring is polished by a grinding instrument to make its width reach factory requirements. The main...
