3, main structure and working principle :

3-1,this machine is upper roller adjust type, and upper roller in middle of two down rolls and drove by lead screw to move up/down and to bend the steel plate.

3-2 the equipment composed of working parts and drive system two parts. The working parts composed of right and left bearing plate , one upper roll, two down rolls (these three rolls material is 45# steel with heat treatment. ), lifting screw and worm wheel and other accessory parts. down rolls drive upper rolls to move. Upper rolls can adjust up/down . drive system composed of main motor, main speed reducer gear and other accessory parts.

3-3 down rolls were drove by main motor and main speed reducer gear, the spindle of main speed reducer drive two down rolls by one group gears, the direction adjusted by the main motor.

3-4 upper rolls lifted by accessory motor and vice speed reducer drive worm pole and worm where of right/left rolls bearing plate.

3-5 unloading device is used for bending circle type to remove the workpiece. while unloading the upper rolls move to up limit position, the balance device on upper rolls ends hit upper rolls to remove the workpiece.
