摘　　要：针对滚焊机调压轮H62黄铜极片批量生产的要求,设计了一副13工步连续级进模用于该制件的成形生产。采用简单工序集中和复杂工序分散成形的办法,将制件的冲压成形的工步优化为13个工步,分别为:①定位孔+切边成形➝②冲孔成形➝③切定位槽成形➝④切筋条➝⑤切筋条➝⑥切边➝⑦切连接筋➝⑧一次翻边➝⑨切边+折弯➝⑩切边+180°折弯➝(11)180°折弯➝(12)切断➝(13)制件落料。模具中,针对折弯A特征的成形实用先折弯后翻边的办法成形,针对贴紧的180°折弯成形,分散为4个工位进行成形;针对带一定间距的180°折弯E的成形,分散为2个工位进行折弯成形,先通过凸模将板料筋条进行圆弧预弯,然后再使用2个滑块进行挤压弯曲成形。模具成形工艺设计合理,模具结构简单实用,较好地实现了制件的自动化生产。A pair of 13-step continuous progressive die was designed to meet the requirements of batch production of H62 brass electrode plate of pressure-regulating wheel of welding machine.By using the method of concentrating the simple process and dispersing the complex process,the stamping process of the part is optimized to 13 steps,they are:①locating hole+trimming➝②piercing➝③trimming locatinggroove➝④trimming➝⑤trimming➝⑥trimming➝⑦trimming➝⑧flanging➝⑨trimming+bending➝⑩trimming+bending-180°➝(11)bending-180°➝(12)cutting➝(13)blanking.In the die,the method of bending first and flanging later is used for the forming of bending a feature,and the forming is divided into 4 positions for the bending of 180°close together For the forming of 180°bending e with a certain distance,the bending process is divided into two work stations,and the plate ribs are pre-bent by the punch,and then the extrusion bending process is carried out by using two sliders.Die forming process design is reasonable,die structure is simple and practical,better to achieve the automatic production of parts.
