| 摘 要： | 对PPNMZ500/60液压板料折弯机的机液伺服阀同步系统工作原理加以分析,针对偏压情况下两缸同步的极限偏差进行分析研究并加以定量计算。计算结果表明:极限偏差lmax必须是限定值,超出限定值lmax则无法满足生产要求。

| Abstract: | The synchronous principle of mechanical-hydraulic servo valve of PPNMZ500/60 hydraulic press brake was analyzed.The limit deviation of two cylinder synchronization under eccentric compression circumstance was quantitatively calculated.The results showed that the limit deviation lmax must be a limited value or the requirement for production can not be met. |
