随着材料和制件品种的不断增多,用户对压力试验机的测力范围也要求不断扩大,特别是对小吨位测力的要求日益迫切。为了满足用户的上述要求,我们对我厂的TY-30型液压式压力试验机进行了改装设计,在原来(0～6)t,(0～20)t的基础上,增添了(0～1)t的测力装置,制成了YE-30A型压力试验机,达到了在一台机器上实现大、小两种测力量程的目的。本文就在研制中的几个理论问题,对照样机的实际检测情况加以论证说明。
With the continuous increase of varieties of materials and parts, users also have to constantly expand the measuring range of pressure testing machine, especially for the demand of small-tonnage force measurement. In order to meet the above requirements of the user, we modified the TY-30 hydraulic pressure testing machine of our factory. Based on the original (0 ~ 6) t, (0 ~ 20) t, 1) t measuring device, made of YE-30A-type pressure testing machine, to achieve a machine to achieve large and small two kinds of measuring range purpose. In this paper, several theoretical problems in the development, the actual prototype test control to illustrate the situation.
