自1958年以来,我厂就采用多刀滚剪床加工变压器硅钢片。到目前为止,经过实践证明,效果仍为显著,裁质优良,颇受工人欢迎。该机床的特点是可以同时剪裁不同宽度的硅钢片,最大剪片宽度为1200毫米,最小剪片宽度为40毫米;长度任意,不受机床本身限制。当成批生产剪裁大容量变压器铁心时效果更为突出,与普通斜口剪床比较提高效率3～4倍。同时可以进行套裁,硅钢片利用率也由原来的70%提高到95%。现将机床的结构、传动原理及操作过程中的几个问题简介如下。
Since 1958, our factory has adopted multi-knife rolling shears to process transformer silicon steel sheets. So far, it has been proved by practice that the effect is still remarkable, the quality of the cut is excellent and the workers are very popular. The machine is characterized by the simultaneous cutting of different widths of silicon steel sheet, the largest clip width of 1200 mm, the minimum clip width of 40 mm; length of any, not limited by the machine itself. When mass production of large-capacity transformers cut the effect of the core is more prominent, compared with ordinary oblique shear bed to improve the efficiency of 3 to 4 times. At the same time can be set up, silicon steel utilization from the original 70% to 95%. Now the structure of the machine, transmission principle and the operation of several issues described below.
