补充资料:封盖落料-拉伸-切边-成形复合模

兰州电机有限责任公司(甘肃兰州 790050) 杨思明
[摘要]分析了封盖零件的成形工艺特点,介绍了此类零件复合冲压模的结构设计。
关键词 封盖 复合模 落料 拉伸

1 零件分析
     图1所示为空气滤清器的封盖,生产批量大,材料为08F,料厚0.35mm,外圆直径个80mm,拉伸高度7mm,成形后口部要求无飞边。该零件是一种典型浅盖零件,该封盖原加工工艺为落料--拉伸--压延,造成口部拉伸后有飞边,需人工清除,费力费时。
2 冲压工艺分析








    经以上计算,可一次拉伸成形,凸凹模环形壁厚强度完全可以满足要求,采用一次成形工艺为:落料--拉伸--切边--成形。
3 模具结构设计与设计要点
3.1 模具结构及其工作过程
    复合棋结构如图3所示。将条料送至凹摸15上,凸凹模12下行,卸料板13压紧条料,凸凹模12与凹模15进行落料,凸凹模12继续下行,落下的圆坏料与已有压边力的压料圈5接触,拉伸凸模6与凸凹模12进行拉伸成形,凸凹模12继续下行,凸模4外圆与凸凹模12内切边模进行切边。凸凹模12再下行,拉伸凸模6与打料板7端面接触,进行压延成形。凸凹模12上行,打料板7在冲床作用下打下成品一次成形结束。

3.2 设计要点
    (1)落料凹模15内孔D尺寸计算时取最小值,在拉伸过程中试模修配拉伸凸模6圆角半径来确定切飞边量。
    (2)拉伸凸模6与凸模4需设计成二个单独体,便于凸模4刃口刃磨,凸模4中心孔设计成螺纹孔便于起模。
