本文介绍了几种材料的压缩螺旋弹簧的应力松弛性能及其影响因素。由于采用热、磁和电强压处理能显著提高各种弹簧的抗应力松弛性能,进而综合利用机、电、热处理及计算机控制等知识,采用模块化设计原理,试制了电强压处理专机(DQY),使弹簧处理快速、高效。 This article describes the stress relaxation properties of several types of compression coil springs and their influencing factors. As the use of heat, magnetic and electric pressure treatment can significantly improve the various types of spring stress relaxation resistance, and then comprehensive use of mechanical, electrical, heat treatment and computer control and other knowledge, using modular design principle, trial production of electric pressure processing special plane (DQY) , So that the spring processing fast and efficient.
