    YWT type hydraulic elbow hot push machine is the important equipment for petrochemical, electric power, urban construction project construction, its working principle is heating steel pipe (including low alloy steel pipe) by intermediate frequency power supply , at the same time the pipe will go forward at a constant speed, the heating part of the steel pipe go along the inner mold and then form a certain radius of curvature and the Angle of the elbow.
    1. When our company design the elbow forming machine, Main frame adopts the design of high precision milling, the beam is made of rolling guide is oriented in order to reduce sliding surface wear to ensure the accuracy of the equipment, the heating process is now relatively mature medium frequency power supply, liquid pressure feed, automatic switch gate. Electrical and hydraulic perfect cooperate, make the operation easy, maintenance is simple. Practice has proved that this machine has stable feed speed, good rigidity, high precision, easy to operate, safe and reliable, strong commonality, advanced and practical features. Processing products can greatly raise high product quality, reduce labor intensity.
    2. The hydraulic system: triple pump station
    Electric brand:Shanghai HuaBin, schneider , Motor/ oil pump / hydraulic components brand : Taiwan Difu. The main hydraulic cylinder run / fast forward/fast rewind, 21 mpa designed pressure. This system consists of the following some basic circuits: there is heavy traffic low noise of gear pump and electro-hydraulic directional control valve fast forward, fast return way; Composed of variable plunger pump and into the oil control volume speed work into the loop; By single pole double-acting hydraulic cylinder rapid movement differential connection circuit, etc. Due to fast forward and fast rewind need large flow, and when workers into the flow is small, so the design will be fast forward, fast and work back into the loop are separate derivation, are independent of each other. And added   the back pressure valve on the run way , thus to improve the work at low speed stability.
