Three Rolls Asymmetrical Bending Machine

The three-roller asymmetric rolling equipment is used for cold working with sheets which thickness within 6mm.It can bend sheet plate into different cylindrical tubes.

It can be used in boiler,chemical industry ,mining,construction ,shipbuilding and other machinery industry.

The 3 rolls asymmetrical rolling machine is mechanical types.The top roller and bottom roller are all main drive roller.The bottom roller lifts up and down to clamp the steel plate tightly.The meshing between the top roller gear and bottom roller gear is to driven the top roller.The side roller move titling to pre-bend the steel plate and circle.It is compact and easy to operate and maintain.

Feature:

1.Small pre-bend straight edge

 2.Designed for small and thin plate to bend the roll cylinders

3.Pre-bend and generator rolling functions helps to ensure the machine can bend the perfect roll at one time.

4.Working Thickness rang from 2mm to 6mm

5.Working Length ranges from 1000mm to 2500mm

6.Simple initial pinch

7.Flexible manual drop end

8.High-efficiency machine processing

9.Specialize in small diameter cylinder bend

10.High quality solid rolls are applied to bend stainless steel

11.Easily-operated hand wheel is used to help lateral roll

Pinch Roll Structure :

1.Pinch Roller ,the pinching rod is for clamping down the materail whihc feeds it through.

2.Forming Roller ,it goes up and down in that angle to get your form as your required.

3.Foot Swith with operate button

4.Handwheel

5.Built -in Snubber for cone bending

6.External Snubber

Standard Component

*Movable control panel

Seperate control panel

Digital display for lateral roll

*Hardened rolls

The top and bottom roller are all main drive roller.

The bottom roller lifts up and down by hand wheel.

The lateral roller title up and down by electric motor

*Machine cover

*Manual drop end 

The release device is manual drop end.

Turn the upper roller to certain angle ,the rolled metal cylinder can be dropped out from one side of the upper roller.

Main motor

The self-braking motor allows the plate to move very slightly,whcih is useful during initial forming

Rotation is by means of a self-braking motor,a reduction -gear and a pinion-crown systems with chain

Optional Equipment

Safety cable

Extended shaft for section bending

Digital readout

W11F asymmetric plate rolling machine working principle

Firstly feeding the plate bewteen top and bottom rolls,the plate is clampped.The side rolls goes up to pre bend the plate.When one side is prebended ,the side rolls go down.Then clamp another side plate.

And the same way pre bending the another side of steel.Then roll it  into cylinder or arc.

Major parts of the manufacturing process:

Working rollers: cast steel ingot (chemical composition analysis): check performance-forging roughcast — forging annealing-UT flaw — roughing (mechanical tests)-heat treatment (hardening and tempering) — UT flaw — semi-finishing — finishing — MT.

Large forgings: cylinder body, gear, gear shaft forging roughcast — surface inspection – roughing — UT flaw — UT flaw detector heat treatment — finishing semi-finishing — MT.

Welding structure: racks, chassis, wheel box Plate into the factory (chemical composition analysis, mechanical properties test) — pretreatment — for sheet metal cutting-welding-seam UT or RT flaw — annealing treatment — roughing-finishing— vibration destressing—hot blasting —finishing 5-4 Major parts of the manufacturing process.
