▀ This hydraulic 3 roller bending machine is wildly used in metalworking industry, to make metal plate into cylinder-shaped, arc shaped, etc, advanced technology from Japan.
▀ The upper roller can moves vertically, moves horizontally, both of the movements displayed digitally.
▀ This machine also has function of pre-bending.
▀ The pre-bending processing by adjusting the upper roller, the lower roller relative to the asymmetric position to achieve.
▀ The two lower roller moves drived by electrical motor and reducer, which can make products with high precision.
▀ The height of the lower roller remain unchanged, so it is easy to operated with.
▀ The rolling machine mainly made up of machine body, hydraulic system and control system.
► Machine body.
The machine body made up of upper roller device, lower roller and horizontal drive device, roller device, over turn device, balance device, lubrication device, right machine frame and left machine frame, and the foundation.
► The upper roller device.
The upper roller device made up of upper roller, main oil-cylinder, bearing seat for upper roller, and double row self-aligning bearings. The two oil-cylinder provide pressure for operating, and the working pressure is 20Mpa. Upper roller’s raw material is 42CrMo, hear treatment meet HB220-280.
