Supply Range and List

★ Feeding Guided Platform

Set the left and right guide device on the feeding inlet of main motor, keep raw material sheet and roll forming system in the right position. The guiding position should be adjusted by manual screw mechanism, and it can be adjusted from left to right independently.

★ Roll Forming System

1)5.5KW；Forming Main Motor Power: 11KW

2) The roll forming system is composed of frame, transmission parts and cold forming roller group.

3) The frame was manufactured segmentally and connected by all pats, the profile was welded integrally.

4) The roller adopts bearing steel, and processed by forging, precision CNC machining and polishing the surface after plating chromium.

5) The roller axle adopts bearing steel and it has been quenched and tempered; its support structure type is conjoined wall plate.

6) The gear reducer motor and chain transmission drive lower roller group rotating, some of up and down roller adopt gear transmission.

7) Adjusting the clearance of up and down roller by manual screw to fit for rolling different thicknesses of sheets. The tolerance of finished plate will change due to different strength and thicknesses of baseboard.

★ Cutting after Forming System

The cutting system is composed of cutting frame, cutting mold, guiding device, cutting cylinder and cutting hydraulic station.

1) The cutting frame adopts welding frame type with well integrally stiffness.

2)The forming mold which the use of cutting mold fits the across-section of sheet will reduce distortion on cut-off point, use cut method to cut off, does not produce waste; the cutter blades material is Cr12 and has been quenched and tempered.

3) The guiding device adopts sliding block structure, which can keep the blade cut off the plate stably under the pressure.

4) The power of cutting off is provided by main motor hydraulic station, hydraulic station motor power:5.5 KW

★ Finished Product Rack

The rack was mainly used to place finished plate after forming to facilitate the handing of operators. This racking device is composed of two racks which the width meets the requirement of finished plate and the length is 2 meters. The frame is welded by square pipe profile, and sets numbers of automatic rotated supporting rollers according to the features of the transmission on the top, the bottom is composed of adjustable screws which can coordinate the height of finished plate in a certain range.

★ Electronic Control System

1) The system adopts PLC control and frequency control technology to realize the automatic production of whole machine.

2) The system provides a friendly human-computer interface that can set batch, working length and numbers

3) Operating type: Touch screen and buttons.

4) Encoder Count has the function of number counting and length counting.

5) PLC. Omolon PLC is been used.

★ Universal correcting head

1. Correction Structure: 3D Turkey correction head, It can be adjusted from left to right to make sure of straightness.

2. Shaft diameter: 58mm

3. Material: Cr12Mov

★ Hydraulic System

1) External independent hydraulic station is adopted (provides the power for cutting off)

2) Main valve parts are domestic well-known brands.
