对于无凸缘引伸件的冲压切边,通常采用水平切边模,但是这种切边模是专用模具,没有通用性。如遇需切边的引伸件品种繁多且生产数量又少的情况下,这种专用水平切边模无疑是不经济的。对此,我们设计制造了一副通用水平切边模架,实践效果良好。 模架结构如图1所示,由16种零件组 For die-cut flaps without flange extensions, horizontal trimming dies are commonly used, but such trimming dies are specialty dies and have no versatility. In case of need to cut a wide range of extensions and the production of small quantities of circumstances, this special level trimming die is undoubtedly uneconomical. In this regard, we have designed and manufactured a common horizontal trimmed mold, the practice effect is good. Formwork structure shown in Figure 1, from 16 kinds of parts group
