具有抗偏载和同步机构的多工位液压机的研制

Design and manufacture of multi-transfer hydraulic press with resistant-bias loading and synchronization mechanism

多工位液压机是一种对金属薄板进行冲压或成形的液压设备,由于具有结构紧凑,生产效率高等优点,在发达国家应用广泛。针对多工位液压机台面宽、偏载严重、成形精度高等问题,本文介绍我公司为汽车零部件成形而研制的一种四柱式多工位液压机。通过对机身结构形式和闭环电液控制系统的研究与分析,提高了设备的运动平稳性能和整体性能,增强了抗偏载的能力,从而满足压制成形精度高的要求。

Multi-transfer hydraulic press,a kind of hydraulic equipment with the compact structure and high-efficiency,is widely used in sheet metal shaping and forming operations in the developed countries.To the problem appeared in multi-transfer hydraulic press,such as the wide table,serious bias loading and high-precision forming etc.,a four-column multi-transfer hydraulic press developed for the forming of auto parts and components was designed and introduced.Through the research and analysis to the mainframe structure style and closed loop electric-hydraulic control system,the stationary motion performances as well as the integrated performances of equipment were improved and the resistant-bias loading capacity was enhanced in order to meet the high accuracy and compaction requirements.
