2000mm Slitting Line

BRIEF INTRODUCTION

This line is used for kinds of wide steel strip into certain width and then recoil them to meet the request for the cold roll forming steel line and high frequency welded pipe production line with the thickness of 1~6mm, and the width of 800mm~2000mm.

BASIC TECHNICAL PARAMETERS

PROCESS FLOW

Coil storage→coil loading→uncoiling→guiding→flattening→feed-to-length→strip shearing→strip transport & kickoff→pallet lifting→longitudinal moving and stack output

INTRODUCTION OF MAIN COMPONENTS

1. Coil loading car

     Put on coil on the machine with functions of cent ration and lean.

2. hydraulic double-cone uncoiler

    one side of conical head rotate automatically with hydraulic clutch. Double-cone can open and shut movement or whole movement with arrester. Conical heads adopts hydraulic expansion.

3. Sheet guider and straightener

     consists of sheet guiding press roll, bending roll, scooping device, and receiving table

4. End shear

    Hydraulic shear, used to divide coil or cut off sheet ends.

5. Centering guide device

Each one group of vertical guide roll is provided of two sides of steel sheet. Each roll group is fixed onto a sliding seat. By adjusting screw thread pair via handwheel, the sliding seat moves along sheet width direction to suit different sheet width.

6. Disc shear

   Use rotating disc shear proper for slitting.Drive power transmitted to upper and lower disc blade shafts via distribution cases; driven by DC55kW motor, whose speed tracks the whole line via PLC control; Machine frame uses stress relieved steel structure, processed as a whole piece; Hydraulic side exit type tool changing. Shear blade provided: totally 20 pieces in 10 sets.

7. Scrap barrel 

    Reel up cut off scrap edge, some of which can be used as baling straps.

8. Spiral accumulator   

    Working principle: Hydraulic cylinder of strip feeding unit holds down steel strip. The feeding motor drives the feeding roll to fill strip into the accumulator by friction force. The main motor rotates supply roll of the accumulator cage to store steel strip in the inner and outer storage zone. The drive motor will stop after one coil finished, and will resume feeding after cutting and welding of another coil.

9. Wrapping and tensioning device

10.Separating and pressing device

11. Electric control and line linkage

12. Full line hydraulic system
