What are plate type
1, mechanical three roller symmetrical bending machine. Mechanical three roller symmetrical bending machine structure formed of three rollers, roll two rolls on Central symmetry vertical vertical movement, won through screw screw worm transmission, two lower roller for rotary motion through the output gear reducer and the lower roller gear, for rolling sheet to provide torque. Mechanical three roller symmetrical bending machine pre-bent plate end via other devices.
2, hydraulic three roller symmetrical bending machine. Hydraulic type three roll symmetric type volume Board machine (three roll volume Board machine) structure type for three roll symmetric type, Shang roll in two Xia roll Central symmetric location for vertical lifting movement, through hydraulic cylinder of hydraulic oil role Yu piston and get, for hydraulic drive; two Xia roll for rotating movement, through deceleration machine of output gear and Xia roll tooth meshing, for volume business plate provides torque. Hydraulic three roller symmetrical bending machine is compact in structure, convenient operation and maintenance.
