本文介绍了肘臂自动机构原理,分析论证了该机构可靠性。时臂自动机构新颖实用,能单独或多个和其他元件组合成复合装置、配置在普通的单行程液压机上,就可以一次连续弯制成常需多次压制才能成型的复杂零件。本机构在锅炉、化工、石油容器等压力制作行业中推广使用,可以获得显著的经济效益。 This article introduces the principle of elbow automatic mechanism, analysis and demonstration of the reliability of the mechanism. When the automatic arm arm novel and practical, alone or multiple and other components combined into a composite device, configured in the ordinary single-stroke hydraulic press, you can make a continuous bending often need to suppress multiple parts to be molded. The agency in the boiler, chemical, petroleum containers and other pressure to promote the use of manufacturing industries, you can get significant economic benefits.
