| 摘 要： | 使用Rm-72型下死点测试仪器对某高速压力机在空载和有载荷两种情况下进行了下死点测量.在空载时改变滑块重量、运转速度、动平衡配重块重量以及运转时间以获取下死点变化数据,并进行比较分析.测试结果表明:滑块重量增大、运转速度提高以及测试时间延长会导致下死点向下偏移,改变配重块重量对下死点变化不明显.在有载荷时通过对不同型号高速压力机进行下死点测试,发现下死点波形存在差异.测试结果表明:随着速度的提高,下死点附近的波形形态发生改变,结构不同的高速压力机存在波形图的差异.该研究结果有助于高速压力机下死点精度控制.

| Abstract: | The bottom dead center of some high-speed press at idle-load and load has been measured by using model Rm-72 BC testing apparatus. The BDC varying data has been obtained and analyzed when changing the slide running speed,weight of slide,weight of dynamical counterbalance or running time at idle-load. The testing results show that if the weight of slide,the running speed or the running time increase,the BDC would deviate downwards, but the variation of the counterbalance's weight would not affect the change ... |
