Metal roller machine

Metal roller 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 four-roller sheet metal roller 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.

Metal roller machine is economical mechanical three-roll plate rolling machine, mainly for the rounding of 4mm to 40mm, 1500mm to 4000mm length plates. It is a very affordable and economical plate rolling machine, the best choice for customers with small processing volumes.

Metal roller machine is the essential sheet metal roller that gives you the fundamental versatility of plate rolling machine with no frills.  Equipped with high quality components with our premium rolling solutions.  Mechanical plate roller features robust metal rolling capabilities and programmable rollers for adding flexibility.

Three roller symmetric structure driven by screw lever and turbine worm. The upper roller moves in vertical direction in the center symmetrical position between the nether two rollers. As the main drive roller for rotary motion, two nether rollers engaged with the output gear of the reducer to provide torque for rolling plate. The metal roller machine is compact and easy to operate with lower maintenance, the metal roller is suitable for installation different dies for rolling various profiles.

Upper roller lifting motion principle – Auxiliary motor and reducer drive the worm and turbine under lateral bearing seats to move, consequently rotate the screw nut on the turbine to lift screw lever.

Equipped with lightning technology, perforation time more shorter, 90% of perforation time can save . Beaml lightning combined with genius improvement so that the perforation will not affected by material quality and complete perfect cutting with the best kerf then save the gas and electricity and other cost as well.

Main feature of symmetrical mechanical metal roller machine

The upper roller can lift and two bottom rollers and move horizontally separately. Bottom rollers perform functions then side roller in return, two types become none symmetrical, then can finish pre-bend and rolling of thin and thick plate at the same time. Besides, it is convenient to roller taper working piece.

  • Easy to use removable console.
  • Two sets of digital output for easy positioning of two lower rollers
  • Suitable for thin and heavy plate, aluminum or sheet metal rolling as well.
  • Ferrules in full circle or varying radius
  • Hydraulic and electrical overload protection.
  • Extended roller shafts for profile and pipe rolling operation.
  • Two sets of digital output for easy positioning of two nether rollers.
  • All rolls mounted with spherical bearing, top rollers guided spherical bearing.

Manufacturing process of main parts for sheet metal roller

  • Working rollers: casting steel ingot (chemical composition analysis). 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) – pretreatment  – for sheet metal cutting – welding – seam UT or Rt flow – annealing treatment – roughing finishing – vibration destressing – hot blasting – finishing.

Metal steel roller working principle and design according to CE standard

  • Offloading device used after the round cylinder have 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 tilting bearing seat ,then the coiled product can emerge from one end of the upper roller .
  • Design meets EU international standards. The fuselage eliminates internal stress by annealing and ensures higher precision and strength. 
  • All machines 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 welded at the whole bottom pallet.
  • 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 adjust 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 transmission part consists of the main motor, speed-reducing motor and other accessories.

Mechanical three roller symmetric structure for metal sheet 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 the bottom roller and supply the torque for bending plate.
  • It’s compact, maintain and very easy to operate.  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.

All important component parts purchased from famous brands for metal sheet roller machine

  • 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, all of the electrical components from Schneider.
  • 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.

Hydraulic system from Japan Yuciyuken or German Rexroth for sheet metal roller machine

  • Yuciyuken integrated hydraulic valve block and hydraulic transmission with high reliability.
  •  And integrated hydraulic system can effectively alleviate problems cause by leakage of hydraulic fluid to improve the working efficiency and rolling precision.

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

  • Operator should be familiar with structure, performance and usage of machine.
  • The operator start roller under specified charger agreement.
  • Carefully check the safety system before start machine.
  • Hands and feet are strictly prohibited on rollers, transmission parts and workpieces during processing.
  • After rolling work interruption, should put clutch on neutral position.
  • When several workers collaborate process, must have guider’s command.
  • No overloading.
  • Up-down and rollover of upper roller, the reset of bearing, also the balance of upper roller, must conduct after main drive close down.
