Intelligent Manufacturing Redefine Your Future!
- Costing less than a four roll bending machine
- The ideal choice for limited production cost.
Rolling Capability: 4mm-100mm
Rolling Length: up to 6000mm or customization
- 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.
- 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.
- With NC controller
- Upper roller can move left and right, lift up and down
- Lower rollers are drive rollers, fixed cannot move, rotate to provide power
- With hydraulic station
- Upper roller universal 3 roll bending machine has pre-bending function.
- Good choice for model above 16x2000, usually buy 40x5000mm to roll wind tower, 20-25x4000mm to make oil pipeline (Specific models according to customers’ plate rolling requirements).
- Lower price compared with 4 roll plate bending machine, but it also can produce cone by add cone device.
- Mechanical 3 rolls plate bending machine
- Simple structure: upper roller is driven roller can lift up and down, and down rollers are fixed driving rollers.
- Cheaper price than other types of 3 roll plate rolling machine
- Not suitable for model larger than 25x2500mm
- Without pre-bending function
- Level Down three rolls roll bending machine is also mechanical rolling machine.
- Lower rollers can move left and right or only one side move, which can adjust to bend cones.
- Can bend cones.
- It has pre-bend function by adjust the center distance of lower rollers.
- High precision and affordable price for small model.
- If customers want to buy large model of level down three roller rolling machine, it need to be change as hydraulic type, which could be more expensive.
- Mechanical type
- Lower roller is driving roll, upper and side rollers are driven roll
- Customer can adjust the side roll to pre-bend workpieces.
- High precision
- It can bend cones by adding cone device.
- Only suitable for small plate rolling machine models.
