Elctro Hydraulically Operated Three Roll Fix Axis - (Model No. 3R----FAEH)

The machine is most economical model which is a fully hydraulically operated machine. All functions like top roll up-down, roll rotation (reverse / forward), drop end frame pulled down and top roll inclination is all by hydraulically actuators.

Advantages :

Specially developed low cost economical fully hydraulically operated machine.
Since all rolls are mounted in roller bearings the electrical consumption is less by 50% compared to conventional pyramid type machine with metal Bush.
Open type rolling requiring mass production qty.
This machine can be used where different operations like rolling, material straightening, Conical rolling, section rolling need to be carried out in single machine.

Special Features

The machine frame is fabricated from all tested steel plate material. A Die Penetration test is carried out on all weld joints to ensure sound weld quality This frame is subjected to stress relieving, sand blasting and epoxy primer painted for corrosion free long lasting machine life.( Primer paint 160 DFT) The complete body frame is machined in CNC machine to achieve built

A tilt able control desk is conveniently located on machine. The main panel start / stop buttons and roll rotation fucntion (Reverse / forward) is provided on the same. The Top roll left side position and right side position are indicated separately by two digital meters

A specially designed & built mechanism allows drop end frame to tilt down in horizontal position without much efforts (one person can perform job). No need to dismantle frame from main body like in conventional machine. The top roll can be tilted to great degree of inclination making it most convenient and ease to remove rolled shells without any difficulty

All our machine rolls are mounted in heavy duty roller bearings. Each roller is fitted with two bearing per side four bearing per roller

A dual cone bending device can be provided as shown. The attachment provided between bottom rolls is suitable for narrow cone diameter. The attachment to be fitted on a main frame is suitable for cone having wide angle.

An extra wide 'Y' type adjustable support rolls mounted in bearings provides best support to bottom rolls & eliminate scratches on top rolls

An extended rolls can be provided for mounting dies to roll different sections like angle, channel, beam, pipe or flat etc

Standard Featues

Both the bottom rolls are driven rolls.
All rolls are manufactured from alloy steel material.
All rolls are mounted on heavy duly ball bearing .Total 4 bearing per roller.
Top roll up down as well as roll rotation is all hydraulic.
Separate digital roll position meter for each side of roll makes it easy to maintain parallelism between top and bottom roll.
Extra heavy central support with bearing to resist point load on roller and for longer roller life.
Hydraulically operated drop end frame for ease of job removal.
A single person can operate the machine while rolling.

Optional Featues

Hardened rolls up to 52-55 RC.
Tilt able top roll for ease of removal 0of duly rolled shells.
Cone bending arrangement between bottom rolls for smaller diameter cone rolling.
Extra heavy cone bending arrangement on frame for bigger diameter cone rolling.
Electrical control panel with moving trolley for all around access to operator.
PLC controls for automatic bending and rolling.
All 3 rolls positively driven for thin material rolling.
Extended shaft for section rolling die mounting for rolling of section like angle, channel, beams, flats, pipes, bar etc.
Sinking type reference plate for initial reference while feeding the plate inside the machine.
