Multi-cylinder control hydraulic system for wire stripping machine

Abstract

The invention discloses a multi-cylinder control hydraulic system for a wire stripping machine. The multi-cylinder control hydraulic system for the wire stripping machine comprises a servo pump groupand servo cylinders, wherein the bottom end of the servo pump group is fixedly connected with the top end of an oil tank; an oil inlet of the servo pump group is fixedly connected with the oil tank through an oil suction hard pipe; an air filter, a liquid level and liquid temperature controller and a servo valve group are separately arranged on one side of the top end of the oil tank; and an oil outlet of the servo pump group is fixedly connected with an oil inlet of the servo valve group through an oil discharging hose. According to the multi-cylinder control hydraulic system for the wire stripping machine, the three servo oil cylinders are arranged to form a delta shape, two servo oil cylinders are pushed upwards and one is pushed downwards, a workpiece is placed on a bracket, the threeservo oil cylinders are supported on the bracket together, the three servo oil cylinders are located on the same circumference, and concentricity is ensured, a displacement sensor can detect the lifting height of a hydraulic telescopic rod, a liquid level liquid thermometer can detect the oil quantity and the oil temperature of hydraulic oil in the oil tank, and a vibration proof pressure gauge measures the pressure of oil in the servo valve group through a pressure gauge joint to prevent equipment damage caused by excessive oil pressure.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a multi-cylinder control hydraulic system for a wire stripping machine. Background technique [0002] With the development of machinery manufacturing industry, the application field of hydraulic drive control technology is becoming wider and wider, especially the wire stripping machine has higher and higher requirements for synchronous drive control accuracy. In hydraulic transmission systems, the application of synchronous control is very common. However, the synchronous control of large flow, high precision, and multiple actuators has always been a technical problem that needs to be solved in the hydraulic industry. Due to the characteristics of liquid compression, leakage, and damping in traditional hydraulic systems, it is very difficult to achieve high-precision synchronous control of multiple hydraulic cylinders. It is very difficult, the oil pressure of the hydraulic oil in the hydrau...
