剪铰式液压剪头剪切力变化分析及其改善

摘要

Based on anatomizing the function theory of universal hydraulic-scissors,the reason to change shearing force and the altering rule in course of cutting were studied. The means to restrain shearing force was offered,and the hydraulic scissors keeping invariable shearing force was designed.%在对目前剪铰式液压剪头工作原理分析的基础上,研究了剪头在剪切过程中引起剪切力变化的原因以及剪切力变化的规律；提出改善剪切力变化的方法,并设计了一种能保持剪切过程中剪切力恒定的机械机构.
