Performance and characteristics

Bending machine for ship building 20x12000

The rolling plate machine suit for making wide arc type work piece.

High precision end pre-bending

Setting length of vertical side freely,add press on upper roller for pre-bending,finishing high precision pre-bending.

High precision work piece

Upper roller is drum type,bottom rollers balance for cooperating adjustment,continual bend,which is used for sheet and thick plate.

Various bend shape

It can roll O,U,R type work piece and stated taper through assistant taper device.O type bend:back bend method;U type bend:front bend method;R bend:Combinations bend method

Struction Principle 

1. The upper roller of the machine make vertical lifting movement at symmetry place of two bottom rollers center, through hydraulic oil in the hydraulic cylinder acting on piston pole, it is hydraulic transmission;

2. Two bottom rollers make rotation movement, motor join bottom roller through gear reducer and universal chain coupler, provide torque for rolling plate machine plate;

3. There are many sets of support rollers in the space from upper roller to two bottom rollers, which can improve rigidity of bottom roller, enables vertical adjustment;

4. On the top of the upper roller, there is a rigid beam;

5. There are many sets of support rollers in the space from beam to the upper roller, which can improve rigidity of upper roller;
