摘要：

为了提高建筑孔板液压成形机冲压系统的运行稳定性，通过引入双蓄能器的方式提出了一种泵控冲压系统，通过协同方式来实现泵控过程，并在Simulink平台开展了仿真分析。研究结果表明：在双蓄能器模式下制动时，被动马达出油口获得了较高的压力，优化了制动性能，实际制动时间比单蓄能器模式缩短了0.3 s。高压蓄能器压力提高至31 MPa时，低压蓄能器的液压油口被开启，高、低压蓄能器均进入能量回收过程，直至制动过程结束。通过低压蓄能器弥补高压蓄能器体积不足的方式实现了压力的快速调节，以确保单蓄能器在高压下也能够满足能量高效回收的需求。本系统的液压系统表现出了很好的高效节能性能，对提高建筑孔板液压成形机液压系统的运行效率具有一定的理论意义。

In order to improve the operation stability of stamping system in hydroforming machine for building orifice plate, a pump-controlled stamping system was proposed by introducing the method of double accumulators. Then, the pump-controlled process was realized by means of collaboration, and the simulation analysis was carried out by Simulink platform. The results show that when baking in the double accumulators mode, the oil outlet of passive motor obtains a higher pressure to optimize the braking performance, and the actual braking time is shortened by 0.3 s compared with that of the single accumulator mode. When the pressure of high pressure accumulator increases to 31 MPa, the hydraulic oil outlet of low pressure accumulator is opened, and both the high and low pressure accumulators enter the energy recovery process until the end of braking process. In addition, the low pressure accumulator compensates for the insufficient volume of high pressure accumulator to achieve rapid pressure regulation, which ensures that the single accumulator can also meet the needs of high efficient energy recovery under high pressure. Thus, the hydraulic system of this system shows good high efficiency and energy saving performance, which has certain theoretical significance for improving the operating efficiency of hydraulic system in hydroforming machine for building orifice plate.
