上钢二厂双滚筒——偏心轴式飞剪机是一台运转正常、性能良好、结构简单,易于加工和投资较少的简单定尺飞剪。呈荣获上海市科技发明二等奖,它特别适用于我国中小型轧钢车间。本文运用矢量介析法导出该类飞剪机运动学参数计算公式,上计算机计算并分析结果,提出改进意见。 On the steel plant double drum - eccentric shaft type flying shear machine is a normal operation, good performance, simple structure, easy processing and less investment in a simple fixed-length flying shear. Was awarded the second prize of Shanghai Science and Technology Invention, it is particularly suitable for small and medium-sized rolling mill in China. In this paper, the formulas of kinematic parameters of this kind of flying shear are deduced by vector analysis method. The computer calculates and analyzes the results and puts forward some suggestions for improvement.
