Closed double-crank precision steel frame press 160~600 TONS Performance feature With high rigidity rack design, they are welded with the use of high-quality steel plates, through relieving of internal stresses, so that stability and reliability of the whole machine in precision are enhanced. Machine adopts high-alloy-steel, two-bent-axle, and two-wide work center, to optimize design. In order to guarantee relative stationarity of machine operation, it is necessary to balance two balancers. Moulding-adjustment precision is as high as 0.1 mm, safe, speedy, and reliable. Through hard oxidation and grinding,such parts as bent axles, gear sets, and connecting rods possess higher combination property and tolerance. Adopt highly sensitive and reliable clutch/brake and internationally top duplex magnetic valve, as well as overload protection devices, to guarantee precision and safety for operation and stop of press rams. Machine’s structural design shall be reasonable, for the convenience of realizing automatic production, reducing cost, and improving eciency. Possess advanced design convepts, low noise, low consumption, and energy saving. CATALOG>> VIDEO CLIPS
