Summary: | The invention relates to a notch trimming and secondary cutting process method which comprises the following steps: straight trimming is carried out on a side line of a gdef section at a bottom flange, and a waste material A is separated; the akb section side line of the top surface is cut open but not cut off, so that no waste is generated; the side line of the side wall bcd section is cut open, and the waste B is separated; the jk section of the top surface is straightly trimmed, and the waste C is separated; according to the method, the trimming process of the end of the longitudinal beam with the flange is optimized mainly through a secondary cutting method. By means of the technology, the purposes of guaranteeing the die strength, improving the trimming quality and reducing the number of stamping procedures are achieved.
本发明涉及一种豁口修边二次切断工艺方法,包括:底部法兰处gdef段边线直修边,废料A脱离;顶面akb段边线切开,但不切断,无废料产生;侧壁bcd段边线切开,废料B脱离;顶面jk段直修边,废料C脱离;本发明主要通过二次切断方法,实现了对带法兰纵梁端头修边工艺的优化。通过此项技术,实现了保证模具强度、提高修边质量,减少冲压工序的目的。 |
