Numerically Controlled Three Roll Variable Axis machine
Numerically Controlled Three Roll Variable Axis machine
Numerically Controlled hydraulic Three Roll Variable Axis Machine
(Model No. 3R----VANCH)
Description
This is a machine model available with pre bending facility and most useful for one of / repetitive type of medium and heavy components.
Advantages
Specially developed hydraulic circuit requiring minimum maintenance.
As the bottom roll axis distance can be varied from minimum to maximum. It covers a wide range of material thickness for pre bending / rolling depending on diameter to be rolled.
Since all rolls are mounted in roller bearings the electrical consumption is less by 50% compared to conventional pyramid type machine.
Specially developed hydraulic circuit to achieve side roll positional accuracy within +-0.2 mm
Since all roll movement and roll rotation is through hydrualic actuator, only one person is required for operating the machine without efforts.
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 movable 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 four 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)
In this type machine all three rolls can be inclined to great degree This makes it most suitable for forming cones with wide diameter difference Also since the machine can work as a press too it can form cone up to full machine capacity If cones are made by press forming method Also a separate dual cone bending attachment can be provided for forming narrow angle cones.
Standard Featues
All rolls manufactured from alloy steel material
The top roll is positively driven by inline mounted planetary gear box and hydraulic motor.
Both the ends of top and side rolls can be tilted to a desired angle for conical bending.
Optional Featues
A special alloy steel material for Hardened rolls. Hardness up to 52-60 RC
All 3 rolls can be positively driven.
A seprate cone bending attachment can be provided for narrow diameter cone forming.
