今年初,我们遵照伟大领袖毛主席关于“独立自主、自力更生”的教导,针对我厂下料冲床吨位小,不能剪切直径较大的棒料的问题,试制了一个25毫米棒料剪切装置。经过半年多的使用,证明它具有效率高、切下的毛坯质量好、安全可靠等优点。现将该棒料剪切装置简介如下。棒料剪切装置(见图1)由上刀板8(活动刀板)、下刀板5(固定刀板)、底板2、复位弹簧7、挡料板14等组成。 Earlier this year, we followed the teachings of Chairman Mao, the great leader, on “being independent and self-reliant.” In light of the small tonnage of the punching machine in our factory and the inability to cut the larger diameter bar stock, we experimented with a 25 mm bar stock shear Device. After more than six months of use, it has proved that it has the advantages of high efficiency, cut the rough quality, safe and reliable. Now the bar shear device is as follows. The bar cutting device (see FIG. 1) is composed of an upper blade 8 (movable blade), a lower blade 5 (fixed blade), a bottom plate 2, a return spring 7, a stop plate 14 and the like.
