摘 要:高速精密数控冲床的主要性能参数众多,且相互耦合,为高速精密数控冲床的综合性能评定带来了比较大的困难。介绍了国内外高速精密冲床的发展现状,按工作原理将其划分为开式曲柄滑块机构、闭式曲柄滑块机构和闭式多杆机构三大类,重点对国内外闭式多杆高速冲床机构的创新设计进展进行了分析。对该三类高速精密冲床的公称压力、行程次数和行程三个主要技术参数进行综合分析,提出一种高速精密数控冲床的综合性能评定方法,利用该指标对国内外高速精密冲床进行综合性能评价。该指标既可以用来区分高速冲床与普通冲床,也可以用来评定高速冲床综合性能。Main performance parameters for high-speed precision press,numerous in variety and mutual for coupling,gives rise to great difficulty in evaluating the comprehensive performance of the press.Therefore,the development status of high-speed precision press at home and abroad is introduced.The presses,according to the working principle,are divided into three categories:open crank slider mechanism,closed crank slider mechanism and closed multi-link mechanism.Analysis on the innovative design progress of closed multi-link high-speed punch mechanism is mainly focused.The three main performance parameters of the three types of high-speed precision presses such as nominal force,strokes and strokes per minute are comprehensively analyzed,based on which,a comprehensive performance evaluation index of high-speed precision punches is proposed.This index is applied to evaluate the comprehensive performance of high-speed precision punch all over the world,and with which high-speed punch can be distinguished from ordinary one,and the comprehensive performance of high-speed punch can be evaluated as well.
