3 Roller plate bending roll has the most common design in the plate rolling machine market, with a fixed top roll and two side rolls swing up for sheet metal pre-bending and rolling.

3 Roller Plate Bending Roll is available in five types:

- SW11 Mechanical Symmetry Three-roller Bending Roll

- SW11X-B Mechanical Level Down Three-roller Bending Roll

- Asymmetry 3- Roller Bending Roll

- SW11SNC Upper Roller Universal Three-roller Bending Roll

- 3-Roller Symmetry Bending Roll for Shipbuilding


Advantages and difference:

- Costing less than a four roll bending machine

- The ideal choice for limited production cost.

- Bend roll sheet metal from 6mm to 100mm thickness

Bending Process

- Feeding: operation roller lift, make the bus line and lower roller lower the bus distance is slightly larger than plate thickness, then the horizontal input steel plate, make the end of the steel plate and the work roller side of the baffle all line contact for the positive.

- Pre-bending one side: moving roller, make the rolled distance B according to the need to determine, according to the work piece curvature roll down on manipulation, manipulation of point of roller rotation of bending of sheet metal ends, on the roller and the lower left roller clamping plate length is 1.5 ~ 2.5 times of thickness; The pressure of oil cylinder is different from plate thickness to 5 ~ 20mpa.

- Pre-bending another side: change the roll position and pre-bend the other end.

- Final bending: the final bend can be divided into several times, generally for 4 ~ 5 times, the roll-down of the roller is in the middle of the plate, and the roll rotation is manipulated to make the rotation direction and the plate feed in the same direction.


Applications:

- Three-roller plate rolling machine is equipment for rolling metal plates into arc-shaped or circular cylinder shaped workpieces, and can roll cone-shaped work pieces within a certain range with the aid of auxiliary equipment.

- Its rolled products are widely used in shipbuilding, boiler, petroleum, chemical industry, metallurgy, hydropower and machinery manufacturing industries.

- 3 Roller Three roll plate bending roll machine is suitable to bend steel or metal roll from 6mm to 100mm thickness.
