四,Each machine parameters

1. Uncoiler

double cone Hydraulic Uncoiler

 

The uncoiler is of the structure of one cone. It contains two main parts: main body and the fix

ed base. The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.hydraulic expanding and Pneumatic driving

 

OD of coil Φ1000-2000mm
ID of coil Φ480-520mm
Width of strip 120-200mm
Thickness of strip 3.5mm
Weight of strip Max5T
Expansion Type Hydraulic expand
Break Pneumatic driving

 

 

  • Straight head and pinch leveling machine

 

This unit is main used to lead the new coil steel head feed into the flattener unit after uncoiler unit bring the coil into the working place.

straight head:Hydraulic

processing pressure:12Mpa

The leveling unit with 2 roll pinch and 5 roll leveling.

pinch roll diameter:Ф180mm

leveling roll diameter:Ф120mm

pinch and leveling motor:11kw

 

 

 

  • Automatic shear and welder

is used to cut the irregular ends of the strips and then connect the strips by welding.

 

Strip width 120-200mm
Welding thickness 3.5mm
Cutting Type automatic shear
Welding Model automatic welding
Hydraulic pressure 12MPa
Working Cycle Max.5Min


 

  • Spiral Accumulator

This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.

press & carry material device:It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit; it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press& carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.

Accumulator frame assemble: include the electric motor, frame , inner circle roll, out circle roll and pressure roll. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.

Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.

technical parameters:

wworking style: change circle diameter:4M

advantage:storage material more, no strike to strip steel surface.

steel coil thickness:3.5mm;

width:120-200mm

carry material going velocity:Vmax=200m/min

hydraulic oil pressure:7Mpa

directly electric motor power of the press & carry:15KW

the electric motor of the accumulator frame : 22KW

 

 

 

  • Forming & Sizing Mill

 

Forming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.
