We are one of the renowned Manufacturers and Suppliers of a wide array of 3 Roll Plate Bending Machines. The 3 Roll Plate Bending Machine has infinitely variable speed of rolling as per requirement. These 3 Roll Plate Bending Machines have faster rolling for smaller thickness. We provide these 3 Roll Plate Bending Machines at rock-bottom prices. The 3 Roll Plate Bending Machines are operated easily and are highly durable.

Width : 2000mm, 2500mm, 3100mm, 3600mm & 4100 mm.

Capacity in Thickness : 12, 16, 20, 25 & 30 mm.

Standard Features : Hardened rolls up to 60 R. C. Cone guide adjustable on button section rolling arrangement digital display for pressure arm A & B. 
Optional Features

• Soft rolls frame mounted cone guide roller
• Fully ground
• Plated and polished rolls for SS, copper or CRC
• Rolling interchangeable profile rolls with/without PU coating for thin & coated metal rolling in profile like GI/color coated sheets
• Material feed table
• Vertical support for large diameter rolling & shell support
• Hardened section bending dies for angle channel, beam, pipe etc.
• Moving console for all around operator movement
• NC/ CNC control for mass production
• Infinitely variable roller speed
• Automatic central lubrication system

 
Unique Features

• Control Panel : The control panel is user friendly & most convenient to operate. All functions like, bending, cylinder movement, cone guide, drop-end, hold & roller rotation start/stop is on panel. Operator can see bending cylinder position as digital display on panel.

• Drop End : Most convenient & easy way to remove rolled shell from machine due to more clearance between bottom & top roll & higher degree of inclination of top roll.

• Cone Guide : Cone guide which is must for taper/conical rolling is provided to be operated by push button & is duly hardened to 55-60 RC hardness with heavy duty bearing within & to be operated from panel.

• Section Bending : An extended shaft provided on both top & bottom roller to facilitate die mounting which enables bending of different sections like, beams, channels, angles, pipes, flats, round/square bar bending. Capacity up to size 200 channel & beam. The operation is by push button on panel.

• Greater Tilting Angle : Greater tilting angle for taper shell rolling with major dimensional difference between small & large diameter.

We offer PLC Based Plate Bending Machine which comes with totally four rolls. The rolls move in a planetary movement in PLC Based Plate Bending Machine about a fixed pivot to get pre bending and bending of edges. Only 3 rolls out of 4 rolls are driven several times to get bending. Our PLC Based Plate Bending Machine offers bending in several shapes like square, round, polycentric, oval parallel and elliptical.

Highlights

• Offers bending in several shapes
• Comes with programmed logic control
• Premium quality
• Durable

We bring forth a wide array of 4 Roll Plate Bending Machine in the market. The 4 Roll Plate Bending Machine has greater efficiency and can perform pre pinching & bending a plate in single pass. There is no sliding friction and full power is utilized for bending, in our 4 Roll Plate Bending Machines. The 4 Roll Plate Bending Machine moves in planetary motion. The 4 Roll Plate Bending Machine can roll more diameters as compared to 3 Roll Plate Bending Machine. The two rollers associated at top and bottom in 4 Roll Plate Bending Machine are operated by G.B. and motor.

Attributes

• No sliding friction
• High efficiency
• Easy to operate
• Low maintenance

 

Minimum Diameter : 1.1 times the top roll diameter

 

Power Utilization : 30%

The machine is most economical model among all plate bending machine and is most useful for small fabrication shop as well as the shop having separate press machine on which pre bending can be carried out. Since this is a rolling only machine all the power is available for rolling purpose and one can roll smallest possible diametrer for heavy thickness plate material. The same machine can also used for plate straightening machine for small left over rolled material which is to be reused after straightening. Also rerolling is easily possible in this machine which enables apple effect correction and out of roundness correction to make it a perfect circular shape to component.

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
