The single head hydraulic nc tube bending machine China consists of a base on which a work stage is arranged, a lower circuit on the work stage, an upper circuit directly above the lower circuit, the upper circuit is driven by the pressure cylinder to press with the lower circuit, and the pressure surfaces of the upper and lower shells are each fitted with semi-circular grooves that correspond to half the elbow, an end of the lower shelf is fitted with a push bar that can move the workpiece to be worked forward along the semi-circular groove; The other end of the lower shell is equipped with a rotating shaft that is connected to the semicircular groove, the head of the rotating shaft is equipped with a thorn that is located in the semicircular groove and corresponds to the inner circle shape of the workpiece to be processed, the end of the rotating shaft is connected vertically to the rotating shaft over the bearing seat, and one side of the rotating shaft is equipped with an automatic sliding mechanism that can push the sleeve on the thorn. The utility model has a high degree of automation, can automatically complete the unloading process after bending the cartridge and quickly eject the finished bending. Compared to the traditional comparison, performance and benefits are advanced and cost and labour intensity reduced.
