剪板机是一种最常用的锻压设备。老式的剪板机都是机械传动的,一般都有宠大的离合器、飞轮、齿轮等零件,结构复杂,体积大。随着液压技术的发展,机械传动剪板机逐步被液压传动剪板机所取代。本文笔者着重分析了目前国内使用的10种国内外液压剪板机的液压原理,介绍了其特点和适用范围,供液压剪板机维修和设计人员参考。 Shearing machine is one of the most commonly used forging equipment. Old-fashioned shears are mechanical transmission, generally have a pet big clutch, flywheel, gears and other parts, complex structure, large size. With the development of hydraulic technology, mechanical transmission shears gradually replaced by hydraulic transmission shears. This article focuses on the analysis of the current domestic use of 10 kinds of hydraulic shears at home and abroad hydraulic principle, describes its characteristics and scope of application for hydraulic shears maintenance and design staff reference.
