`Each machine parameters

1,Uncoiler

 

The uncoiler is of the structure of double expansion and cantilever mandrels. It contains two main parts: main body and the fixed base. The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.

There are two mandrels on the main body. Each mandrel consists of four-bar linkages that could move radially at the same time. The four-bar linkages in two groups are fitted on two shafts respectively. Powered by air cylinder, they expand and contract radially. When one mandrel is uncoiling , the other one on the other end contracts to load a new coil and sustain it by expansion, which is then fitted with shield arm on the mandrel to prevent the coil from loosening during uncoiling. When the uncoiling operation of the mandrel in working is finished, pull down the positioning pin shaft and turn the mandrel for 180°manually. Then push the pin shaft back to its positioning slot. Now the new coil is in the working position. The cycles repeat in this way.

OD of coil Φ1000-2000mm
ID of coil Φ480-520mm
Width of strip 14-17.3mm
Thickness of strip 2mm
Weight of strip Max1.5T
Expansion Type Hydraulic expand
Break Pneumatic driving

 

 

2.Automatic shear and welder is used to cut the irregular ends of the strips and then connect the strips by welding.

 

Strip width 14-17.3mm
Welding thickness 2mm
Cutting Type automatic shear
Welding Model automatic welding
Hydraulic pressure 12MPa
Working Cycle Max.4M
 

 

 

 

3,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:

working style: change circle diameter:2.5M

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

steel coil thickness:2mm;

width:40-54mm

carry material going velocity:Vmax=200m/min

hydraulic oil pressure:7Mpa

directly electric motor power of the press & carry:7.5KW

the electric motor of the accumulator frame : 15KW

 

 

4,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.
