Manufacturer of Four Roll ((4-roll) Section Bending Machine in Pune, India

Details of Four Roll Section Bending Machine

In this type of 4 roll section bending machine the bottom roll works as apinch roll and the material is clamped firmly betwwen top and bottom roll .The side roll advances to give desired radious of bending. Since the bending force is applied nearer to clamping point the unbend portion of section left straight is at minimum. Due this working principle of machine the straight portion of section is at minimum which increases effective material utilisation.
Planetary guides for Dies

The adjustable pusher arm is used to push the section out in Z axis to form a coil. The pusher arm design gives a great flexibility of adjustment to accomodate smaller to bigger diameter component coil forming.

Movable Centre console

The electrical and PLC with HMI model comes with movable control console enabling to perform operations from a distance.

Precise Section Bending System

The finished components are perfectly round within close tolerances and also the straight portion of section remained ubend is at minimum.

Control Units

For electrical and PLC model all controls are conveniently located on panel. Both the model are provided with auto/manual mode of operations and can be selected as desired.

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 4 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
