Abstract：

In order to solve the problem of using multiple sets of cutting tools when cutting the same series of plates with different widths, a split shearing device that could adapt to cutting plates with various widths was studied to solve the problems of multiple cutting tools and frequent tool replacement caused by traditional shearing modes, and the split shearing system was studied by the method of combining theoretical design calculation with test. Then, a three-dimensional model of split shearing device was established, and the strength and stiffness of critical structural components were analyzed and calculated. Furthermore, according to the function and action requirements of cutting tool, the corresponding high and low pressure hydraulic system and electrical protection device were designed. On the manufactured test machine, the various functional action indicators and production efficiency of the system were tested, and the shearing quality of cutting tool was tested. The test results show that the split shearing system realizes the function of using a pair of cutting tool to cut plates with various widths, and its production efficiency and shearing quality meet the design requirements.
