摘要：

为了解决冲模机对最大冲裁速度的限制问题，设计了一种快速闭式液压系统。在进行快进、快退的过程中，主缸在快速缸的带动下实现被动升降，由柱塞缸与充液阀共同构成快速闭合系统；进入冲裁阶段时，蓄能器与定量泵一起组成油源，将油液压入柱塞缸中。仿真结果表明：当充液压力降低后，蓄能器表现出更快的反应速度，预充压选择7 MPa作为最优值；在满足充液速度不对冲裁频率造成影响的条件下应选择更大的体积，最终选择40 L作为最优体积；设定充液阀的最优初始开口量为5.0 mm时，存在一定程度的超调量，可以根据负载进行快速反应；节流孔直径为Φ2.0 mm时，可以在最短的时间内进入稳定状态，并且不会引起波动现象，表现出了优异的调速性能。

A rapid closed hydraulic system was designed to solve the limitation problem of the maximum blanking speed for stamping machine. In the process of fast forward and backward, the master cylinder was passively lifted and lowered by the fast cylinder, and a rapid closed system was constituted by plunger cylinder and filling valve. When entering the blanking stage, the accumulator and the quantitative pump together formed an oil source to hydraulically pump the oil into the plunger cylinder. The simulation results show that the accumulator shows a faster reaction speed when the charging pressure is reduced, and 7 MPa is selected as the optimal pre-charging pressure. Under the condition that charging speed does not affect blanking frequency, a larger volume should be selected, and 40 L is finally selected as the optimal volume. When the optimal initial opening amount of charging valve is set to 5.0 mm, there is a certain degree of overshoot, and the rapid response can be made according to the load. When the throttle orifice diameter is Φ2.0 mm, it can enter a stable state in the shortest time without fluctuation phenomenon, showing excellent speed regulation performance.
