Sheet metal rolling machine

Sheet metal bending machine adopts a strong electric welding structure, equipped with a super large steel roller. The side roller moves on a linear guide, bending the material near the tight point, thus ensuring that the device’s performance is comparable to that of the more expensive three-roller plate bending machine. In addition, the bending roll motion of the series three-roller plate bending machine ensures optimal traction. For asymmetric geometry and thin sheet, it can effectively prevent it from sliding during the pre-bending process.

Such metal sheet roller is economical plate bending machine, it has a pre-bending function for a maximum of 6mm and a minimum of 2mm; the length is between 1000-2000mm, and it is one of the best choices for thin plates.

RF asymmetry sheet metal rolling machine is specially made for deliver value, reliability, and performance. The sheet metal rolling machine is purposefully crafted to be a practical and flexible rolling solution. Featuring tried and many years tech. Get capacities reserved for elite metal rolling with sheet metal rolling machine.

Sheet metal rolling machine is a kind of equipment that uses work rolls to bend sheet metal. It can form parts of different shapes, cylindrical and tapered. It is essential processing equipment. The working principle of the sheet metal rolling machine is to move the work roll through the action of hydraulic pressure, mechanical force, and additional external parties to make the plate bend or bend into shape. According to the rotation, movement, and position changes of work rolls of different forms, sheet metal roller can process parts such as the oval, arc, and cylindrical elements.

Adopting roller asymmetrical structure with the upper roller moving vertically in the center between the two nether rollers. Metal roller is achieved through the drive of the screw, the worm and the lead screw.

Nether two rollers rotates and provides the plate materials with torque through the engagement of the output gear of the moderator with the gear of the lower rollers.

Structure of asymmetrical sheet metal rolling machine

  • Equipped with 3 rollers asymmetrical structure with the upper roller as the main drive and the nether rollers making vertical movement so as to clamp the plate materials tightly.
  • The machine drive comes from the engagement between the gear of the nether roller and the gear of the upper roller.
  • Advanced design reduces the distance between the bending points to a minimum, ensure the bending precision.
  • The wide roll support with lubrication circuit is mounted within linear slides to prevent wear and tear.
  • The very high rotation power is a guarantee of the superior rolling torque and speed, as all three rolls are driven independently by gear and gearboxes directly to the roller shafts without loss of energy.

Main features of mechanical sheet metal rolling machine

  • The upper roller can lift and two bottom rollers can move horizontally separately or synchronously.
  • After bottom rollers performs functions then side roller in return, two types become none symmetrical. Then can finish pre-bend and roller of thin and thick plate at the same time.
  • Easy-to-use removable console.
  • Two sets of digital output for easy positioning of two lower rollers.
  • Suitable for thin plate, aluminum or metal sheet rolling.
  • Ferrules in full circle or varying radieses can be done easily.
  • Hydraulic and electrical overload protection.
  • Two sets of digital output for easy positioning of two nether rollers.
  • All rolls mounted with spherical bearing, top rollers guided spherical bearing

Sheet metal rolling machine control system

  • Human machine interface with intelligent operation system.
  • Self-compensation standard with high efficiency and safe function as well.
  • Meet standard of CE and ISO9001 requirement.
  • Semi-automatic controlled by the system, there’s no need additional processing steps for bending the ends for professional engineer.

Manufacturing process of main parts of metal sheet roller machine

  • Working rollers: Casting steel ingot (chemical composition analysis): Check performance-forging annealing – UT flow-roughing (mechanical tests) – heat treatment (hardening and tempering) – UT flow-semi finishing – finishing.
  • Large forgings: Cylinder body, gear shaft forging roughcast – surface inspection – roughing – UT flaw – detector heat treatment – finishing semi – finishing.
  • Welding structure includes Rack, chassis, wheel box.
  •  Plate into the factory (chemical composition analysis, mechanical properties test) for sheet metal cutting – welding – seam UT or Rt flow – annealing treatment – roughing finishing – vibration destressing – hot blasting – finishing.

Working principle and design of metal roller for stainless steel or other metal sheet according to CE

  • The offloading device is used after the round cylinder have been finished, before leaving the left bearing seat, raised the upper roller to standard height.
  • And make the upper roller stop with balance pull rod at the bottom of upper roller, then draw out pin shaft on the titling bearing seat, overturn the tilling bearing seat, then the coiled product can emerge from one end of the upper roller.
  • 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.
  • 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.

Structure style of sheet metal rolling machine

  • 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 bottom roller.
  • Metal roller supplies the torque for bending plate.
  • 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.

When you operate the metal rolling machine what should we note ?

  • Operator should be familiar with structure, performance and usage of metal roller.
  • The operator can turn on roller under specified charger agreement.
  • Carefully check the safety system before start sheet metal roller.
  • Hands and feet are strictly prohibited on rollers.
  • After work interruption, should put clutch on neutral position.
  • The up-down and rollover of upper roller, the reset of bearing, and the balance of upper roller, must conduct after main drive close down.
