The double-machine linkage CNC hydraulic press brake machine is to connect two bending machines to perform bending processing. Two press brakes and two operating systems can work together or separately. The rear gauge and front feeding device are specially designed for large workpieces, which can reduce labor intensity and improve work efficiency. The whole machine frame adopts an all-steel welded structure ,has high strength and rigidity. It is equipped with the DA series imported from the Netherlands , ESA series ,and the CYB series from the Swiss CYBELEC company. The main oil cylinders on both sides are synchronously used German imported electro-hydraulic servo valves and imported grating rulers to form a closed loop. Control, the sliding block runs accurately, so as to ensure the bending accuracy and the repeated positioning accuracy of the sliding block. The compensation can be automatically adjusted by the numerical control system, which is convenient and accurate. The hydraulic system adopts the integrated control system imported from Germany to improve the working stability of the machine tool. The two-machine linkage CNC hydraulic press brake machine cooperates with different bending dies to manufacture various workpieces, which are widely used in aircraft, ships, automobiles, mechanical engineering, street light poles, power poles, wire lamp poles and other related industries.
