Abstract

一种有压边装置的首次拉深模，它由销、打料杆、推板、垫板、凹模、凸模、压边圈、顶杆组成。它是将压边装置和凸模安装在下模，凹模安装在上模，同时压边圈起定位和卸料作用，拉深后，凹模上行，压边圈恢复原位，将零件从凸模上脱出，使零件留在凹模内，由打料杆推出零件。

Description

一种有压边装置的拉深模
技术领域
本发明涉及到金属冲压模具，是一种有压边装置的拉深模。
背景技术
目前，公知的拉深模按工艺顺序分有首次拉深模和以后各次拉深模，按使用的设备可分为单动压力机用拉深模，双动压力机用拉深模，三动压力机用拉深模，按工序的组合又可分为单工序拉深模，复合模和连续拉深模。而上述模具机构，由于模具没有采用导向机构，并由下模板底孔落下，模具安装时由校模圈完成任务，凸凹模的对中，工作时才将校模圈移走，虽然模具结构简单，制造方便，一般用于材料塑性好，相对厚度较大的工件拉深，由于拉深模要深入到凹模下面。所以，该模具只适用于浅拉深，为了克服上述模具机构的不足，特提供如下一种模具机构。
发明内容
本发明是提供一种有压边装置的拉深模，它是这样实现的，压边装置和凸模安装在下模，凹模安装在上模，采用首次拉深模结构形式，图中(7)为弹性压边圈(起定位和卸料作用)，压边力由连接在下模座上的弹性压边装置提供，工作时，坯料在压边圈上定位，凹模下行与工件接触，拉深结束后，凹模上行，压边圈恢复原位，将零件从凸模上脱出，使零件留在凹模内，最后由打料杆将零件推出凹模。它解决了普通模具只适用于浅拉深，不适合深拉深的技术难题，同时，它动作十分可靠，压力传递良好，模具结构简单，制作方便，也可适用厚度较大的工件深拉深。一种有压边装置的拉深模，其特征是：销(1)与打料杆(2)配合，推板(3)紧固连接在打料杆(2)上，垫板(4)、凹模(5)压边圈(7)用连接螺钉紧固，顶杆(8)与下模板连通。
附图说明

具体实施方式：
图中所示是一种有压边装置的拉深模，压边装置和凸模安装在下模，凹模安装在上模，采用首次拉深模结构形式，图中(7)为弹性压边圈，它同时起定位和卸料作用，压边力由连接在下模座上的弹性压边装置提供。工作时，坯料在压边圈(7)上定位，凹模(5)下行与工件接触，拉深结束后，凹模(5)上行，压边圈(7)恢复原位，将零件从凸模(6)上脱出，使零件留在凹模(5)内，最后由打料(2)将零件推出凹模。
