摘要：

为解决同一系列不同宽度板材切断时需用多副切断刀具的问题，研究了一种可适应多种宽度板材切断的分体式剪切装置，解决传统剪切模式带来的刀具多、刀具更换频繁的问题。采用理论设计计算与试验相结合的方法，对分体式剪切系统进行了研究，建立了分体式剪切装置的三维模型，分析计算了重要结构件的强度和刚度。根据剪刀的功能及动作要求，设计了相应的高低压液压系统及电气保护装置。在制造的试验机上，测试了系统的各项功能动作指标及生产效率，检测了剪刀的剪切质量。测试结果表明：分体式剪切系统实现了一副剪刀切断多种宽度板材的功能，其生产效率和剪切质量达到了设计要求。

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.
