FEATURES:
Easy adjustment, good weld seam quality, rigid machine structure and easy operation and maintenance. Horizontal roll stand and vertical roll stand share the same quick-change base, which makes the roll can be take off from the drive shaft easier, and save more time. The forming stand arrangement of this line uses double radius pass design.
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. leveler
Made of two row rollers with same diameter. Up roller installed on the memorial torch stand. Rollers equipped interlacing. Initiative roller is driven by gear box through universal joint. Roller leveler is straightened by two row rollers.
4. Cutter & welder
Mainly use for cutting ends and welding together to guarantee mill working continuously.
5. 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.
6. Forming and Sizing main unit
To adopt FFX forming technology.
7. Copy milling saw
Cut the pipe according to fixed length, and send them to the downstream roll table.
8. Electric control and line linkage
9. Full line hydraulic system
