一种铰链式精密剪切装置结构设计

摘要

通过分析比较现有的精密剪切下料方法,根据精密剪切原理和铰链机构的运动特点,研究了一种新型的适用于普通机械压力机的铰链式精密剪切装置,根据该装置的结构形式、工作过程和工作原理,分析了剪切装置结构对棒料剪切质量的影响因素,设计了铰链式精密剪切装置的主要组成部分:动刀架、定刀架和剪刃.此装置可以实现对直径Φ30 mm的热轧棒料的精密剪切,具有结构简单,工作可靠的特点.%The present methods for shearing blanking precisely are analyzed and compared. According to the principle of precise shearing and the features of movement of the hinge mechanism,a new kind of precise shearing mechanism is designed; its structural form, working process and the principle are also discussed. The design process of the main components including a motive tool carrier and a fixed tool carrier is described. The results indicated that the new-typed precise shearing mechanism can achieve the shearing for bars and it is simple in structure and reliable at work.
