A plate rolling machine is a machine that will roll different kinds of metal sheet and plate into a round or conical shape. It can be also called a "sheet metal roller machine", "roll bending machine" or "plate bending machine". GLDMA provide all different kinds of technology to roll the metal plate.
1. Four roller plate bending machines have a top roll, the pinching roll, and two side rolls.
The metal bender roller driven by hydraulic motor. Through the friction between the metal plate and the top roller to drive the bottom roller and side rollers rotate. And supply the torque for bending plate. The bottom roller, side roller and drop end are all driven by hydraulic tank. The bottom roller move up and down, the side roller move along with an arc. The bottom roller rising to clamp the plate and the side roller title up to pre-bend the end of the plate. Our W12 hydraulic plate rolling machine with 4 rolls are more precise, productive, versatile, faster, safer and easier to operate than our 3 roll plate rolling machines as they are less dependent on operator competence. If you are looking for the fastest and most accurate plate roller machines, our four roll bending machines come highly recommended.
2. Three roller plate bending machines have one pressing top roll and two pressing side rolls.
The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders. All these rolls are driven with a combination of planetary gear boxes and hydraulic motors providing superior torque, speed and distribution of powerful forces to pre bend and roll the toughest of materials. All of our plate rollers have a strengthened machine body constructed of stress-relieved high-yield steel, strengthened bearing guidance system, super strong brakes and rolls machined with optimum crowning.
It widely used in different industry field, like pressure vessels, machinery, hydropower, construction. Through the friction between the metal plate and rollers, it can pre-bend, roll round barrel shape, and also has a function of adjusting circle shape and leveling.
W11 series 3 rolls mechanical symmetrical rolling machine
1. The design meets EU international standards.The fuselage eliminates internal stress by annealing and ensures higher precision and strength All machines are designed using SOLID WORKS 3D programming and made with enhanced ST44-1 quality steel with the latest technology.
2. Consists of the operation part and the transmission part which is welded at the whole bottom pallet. The operation part consists of left and right bearing housing, one upper roller, two lower rollers, lifting gears and some accessories. The lower roller is the main one, the upper roller can be adjusted to the height. The transmission part consists of the main motor, speed-reducing motor and other accessories.The operation part consists of left and right bearing housing, one upper roller, two lower rollers, lifting gears and some accessories. The lower roller is the main one, an upper roller can be adjusted to the height. The transmission part consists of the main motor, speed-reducing motor and other accessories.
3. The structure style of this machine is 3 roller symmetrical. The top roller does the movement of elevation in the central position of the two bottom rolls.It's transmitted by screw nut and worm gear.Two bottom rolls are main drive rolls.They rotate by the meshing between the output gear of the gear box and the bottom roller and supply the torque for bending plate.It's compact, maintain and very easy to operate.
4. The main components are: three 45 steel forged rollers, HRC3545, the support frame is welded, the process after being welded, the lower pallet is a welded part. Ball bearing screw and worm gear are 45 steel forged parts.
5. The lower roller is driven by the main motor through the main reducer. The main reducer output shaft transmits to the two lower rollers through a group of the gear wheel. The roller driving direction is switched by the main motor.
6. The offloading device is used after the round cylinder have been finished. Before leaving the left bearing seat raises the upper roller to standard height, and make the upper roller stop with balanced pull rod at the bottom of upper roller. Then draw out pin shaft on the tilting bearing seat, overturn the tilting bearing seat, then the coiled product can emerge from one end of the upper roller.
