剪裁直线边缘的金属板料毛坯,最经济的方法是用剪板机进行剪切。因此,剪板机在许多工业部门得到了广泛的应用。当前剪板机的发展趋向是提高剪切质量、提高生产率、减轻劳动强度和实现自动化。但是,在多品种小批量的情况下,往往需要在大张板料上进行套裁下料,甩传统结构的剪板机来剪裁,不但材料利用率不高,而且工效低,劳动强度大。显然,
Cutting the straight edge of the sheet metal blank, the most economical way is to use shears for cutting. Therefore, shearing machine has been widely used in many industrial sectors. The current development trend of shears is to improve the cutting quality, increase productivity, reduce labor intensity and automation. However, in the case of many varieties of small batch, it is often necessary to cut the material on a large sheet of material and to tailor the traditional structure of the shearing machine, not only the material utilization rate is not high, and the working efficiency is low and the labor intensity is large. Obviously,
