This machine is specially designed for producing various copper parts by hydroforming method.
This machine adopts special three-beam-four-cloumn structure. Three beams are made by solid steel plates, avoiding weld deformation and stress deformation, thus assures working precision.
Four columns are made by 45# steel, tempered and hardened and rigid chrome coated, long life. Slides are made by nodular cast iron, good anti-wearing and guidance quality.
Two side cylinders are energized by gear synchronuous shunt motor, high synchronization, less electric power consumption.
Blank tubes are fed into machine by automatic feeding device and 4-axis robot.
Automatic feeding device is comprised of hopper elevator and blank tube ordering table. 4-axis robot will take one or more blank tubes and load into hydroforming mould.
Grating ruler is provided for safety purpose.
