通过对管端增厚机液压系统的分析,发现液压系统卸压时,液压缸卸压腔容积大,积蓄的能量多,是造成系统卸压振动的根本原因。通过调整液压缸实际行程在其总行程中所处区段不同,减小了卸压腔的容积,降低了卸压时释放的能量,合模缸卸压释放的能量减小为原来的1/3,挤进缸卸压释放的能量减小为原来的1/2,从而解决了系统振动大的问题。

By analyzing the hydraulic system of the pipe end thickening machine, it is found that when the hydraulic system is depressurized, the volume of the pressure relief chamber of the hydraulic cylinder is large and the energy accumulated is large, which is the root cause of the system pressure relief vibration. By adjusting the actual stroke of the hydraulic cylinder in different sections of its total stroke, the volume of the pressure relief chamber is reduced and the energy released during pressure relief is reduced. The energy released by the pressure release of the clamping cylinder is reduced to 1 / 3, squeeze into the cylinder release of energy to reduce the release of the original 1/2, thus solving the system vibration problem.
