剪切机的运动学分析

The Kinematic Analysis of Shear

剪切机是工业生产中常用的设备 ,广泛应用于剪切各种材料。某厂使用的小型剪切机因生产需要将其改装成自动剪切设备 ,但理论上难以确定其最小剪切性能。笔者采用图解法对其进行运动和受力分析 ,得出在调速电机转速一定的情况下能够剪切的钢材直径 ,对生产使用具有较高的理论指导价值。

Ashearis widelyused in cuttingvarious of materials in the industry.Asmall-sized shearwhich is reequipped to an automated one in some factory is difficultto be determined the mininumcapability of shear.In this paper,the movement and stress are analysed in graphic method,and the diameter of the steel which can be sheared is gotten under a fixed rotational speed of adjustable-speed motor,and it is reference to production.
