本厂生产的携带式直流电工仪器的矩形外壳,是用2毫米厚的铝板引伸而成。由于外形尺寸较大(最大达300×230×104毫米),按一般的切边方案,如:分四次冲切。导板式水平切边模切边等都不适宜。根据产品要求和本厂设备条件,我们设计制造了如图1所示的水平切边模,经多年使用效果良好。工作时,将工件放入凹模20,上模下降,支承板12的凸缘拨开脱料钩13,支承板4和12一起支承于凹模面上,脱料钩在扭簧16的作用下弹回,钩住件12的
The factory production of portable DC electrical equipment rectangular shell, is made of 2 mm thick aluminum extension. As the larger size (up to 300 × 230 × 104 mm), according to the general trimming program, such as: punching four points. Guide horizontal edge trimming and so are not suitable. According to the product requirements and the factory equipment conditions, we design and manufacture the horizontal trimming die shown in Figure 1, after years of good results. Work, the workpiece into the die 20, the upper die down, the flange of the support plate 12 to pull off the hook 13, the support plate 4 and 12 together support the die surface, the removal of the hook in the role of torsion spring 16 Bounce off, hooking on piece 12
