适用于折弯机的专用比例阀

Special Proportional Valve for Press Brake Machine

介绍了一种通过改变阀芯机能而满足折弯机高速、平稳、准确和同步控制的专用比例阀解决方案。通过对折弯机的工况特点分析,得出了附带压力与阀芯机能的相互转化关系。试验结果表明,专用比例阀有效解决了附带压力问题,提高了控制效果。

This paper introduces a solution of applying modified special proportional valve to meet the press brake machine＇ s requirements of high speed, stable, accurate and synchronized control. Through the analysis of the char- aeteristics of the press brake machine, the relationship between the pressure and the spool function is obtained. The test results show that special valve is an effective tool in solving pressure problems and improving the control effect.
