Three Roll Section Bending

More About Three Roll Section Bending

The latest in the 3 roll section bending machine design which gives advantage of 4 roll machine ( the bottom roll workind as a pinch roll) which enables clamping of sections at the centre between top and bottom roll to reduce distance between pinch roll and bending roll. Due this working principle of machine the straight portion of section is at minimum which increases effective material utilisation.
Planetary guides for Dies

Thanks to the planetary guide swing arm type working principle. Due to swing arm movement the force being applied by hydraulic cylinder is much more because of leverage available or for the same force the input power needed is less. Also there are very few moving parts and there are no friction creating surfaces as in rectilinear guide type systems the overall maintenance cost is much reduces.

Movable Centre console

The different model than are available are as under :

  • manual hand lever operated machine (as shown in the image)
  • Electrically operated with joy stick and push button
  • PLC with HMI
Gear boxes

All our 3 roll section bending machine comes as a all 3 rolls positively driven by planetary gear box and hydraulic motor directly mounted on roller shaft.

Hydraulic cylinder

The adjustable support is provided at the nearest possible point adjacent to pinch roll. Which helps to bend the trailing end of section up to the end leaving a minimum portion unbent.

Standard Featues

  • Both the bottom rolls are positively driven by palnatery gear box and hydraulic motor directly mounted in line with roll shaft
  • The swinging control console gives liberty to operate machine from front or from one side which also makes it possible to remove rolled sections from front without any problem.
  • All our section bending machine model comes with roller mounted in ball bearing which reduces friction and enhanced torque is available for rotation which other wise will go to waste if plain bush are use which create lot of friction due to metal to metal friction.
  • All our machine has 2 digital meter to ascertain both the roll position and by maintaining same values one can get repetitively same size of rolling

Optional Features

  • All 3 rolls positively driven
  • Electrically operated control console for machine operation from a distance
  • PLC with HMI for automated component bending/rolling cycle.more than 100 rolling cycles can be saved and recalled at any given time .
  • Force lubrication system.
  • Section feeding and locating device
  • Hold bracket for Rolled component
