Description

一种复合冷冲模A compound cold die

技术领域 technical field

本实用新型涉及模具制造领域,特别是涉及一种复合冷冲模。 The utility model relates to the field of mold manufacturing, in particular to a composite cold stamping die.

背景技术 Background technique

目前,对于底部带小孔且有凸缘的一次拉深件成形的基本冲压工序为:落料、拉深、冲孔、切边,具体有以下四种成形工艺方案: At present, the basic stamping process for forming a deep-drawing part with a small hole at the bottom and a flange is: blanking, deep drawing, punching, and edge trimming. Specifically, there are the following four forming process schemes:

(1)    落料、拉深、冲孔、切边单工序成形; (1) Single process forming of blanking, deep drawing, punching and edge trimming;

(2)    落料、冲孔先复合,再拉深、切边单工序成形; (2) Blanking and punching are compounded first, and then deep drawing and edge trimming are formed in a single process;

(3)    落料、拉深先复合,再冲底孔和切边复合成形。 (3) Blanking and deep drawing are compounded first, and then the bottom hole is punched and the trimming is compounded.

(4)    落料、拉深、冲底孔先复合,再切边成形; (4) Blanking, deep drawing, and punching holes are compounded first, and then trimmed to form;

通过分析,方案(1)模具结构简单,但需要4副模具,效率很低,且不能生产高精度的冲压件;方案(2)、(3)、(4)结构稍微复杂一些,且需要2副以上模具,效率精度有较大程度提高。这四种方案远远不能满足现代生产高精度、低成本、高效益的要求。 Through analysis, scheme (1) has a simple mold structure, but requires 4 sets of molds, which is very inefficient and cannot produce high-precision stamping parts; schemes (2), (3), and (4) have slightly more complicated structures and require 2 The efficiency and accuracy of molds above the pair are greatly improved. These four schemes are far from meeting the requirements of modern production with high precision, low cost and high benefit.
