目前国内对大型液压设备的工作台面要求越来越大,精度要求越来越高,尤其是四角调平精度,现在只有极少数国家有能力设计制造能够满足要求的液压设备,但费用比较高。文中通过多轴同步控制技术和液压比例伺服控制技术相结合,使YT71S-3500玻璃钢液压机的四角调平精度控制在0.05 mm以内,达到了国际先进水平,结束了高端液压设备完全依靠进口的局面,增强了国产大型液压设备在国际市场的竞争力。
At present, there are more and more requirements on the working table of large-scale hydraulic equipment in our country, and the accuracy requirements are getting higher and higher, especially the leveling accuracy at four corners. Now only a few countries have the ability to design and manufacture hydraulic equipment to meet the requirements, but the cost is relatively high. Through the combination of multi-axis synchronous control technology and hydraulic proportional servo control technology, the four-level leveling accuracy of YT71S-3500 FRP hydraulic press is controlled within 0.05 mm, reaching the international advanced level and ending the situation that high-end hydraulic equipment relies entirely on imports. Enhance the domestic large-scale hydraulic equipment in the international market competitiveness.
