III. Each Machine Parameters and Specifications:

(1) Uncoiler


Double expansion and cantilever mandrels


1. double expansion and cantilever mandrels.

2. Contains two main parts: main body and the fixed base.

3. Equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.

4. Mandrel consists of four-bar linkages that could move radially at the same time.

5.The four-bar linkages in two groups are fitted on two shafts respectively. Powered by air cylinder, they expand and contract radially.

OD of coil Φ1300-1760mm
ID of coil Φ508mm
Width of strip 39-160mm
Thickness of strip 0.5-2.5mm
Weight of strip Max5.0T
Expansion Type hydraulic
Break Pneumatic driving
Rotate manual


(2)Shear & Welder


It is used to parallel cut the tail of the steel strip, which has just gone into the accumulator, and the head of the strip coming out of uncoiler, and then weld them together.


Hydraulic Shearing and manual welding Strip steel width: 39mm-160mm Strip steel thickness: 0.5-2.5mm Centering way: manual

(3) Spiral accumulator


  • This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.
  • 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
working style: change circle carry material going velocity Vmax=240m/min

No strike

Pinch form



steel coil thickness 0.5-2.5mm diameter 4.2m
width 39-160mm storage area 3.5 m2
electric motor power of the press & carry AC 11KW
the electric motor of the accumulator frame AC 15KW


(4) Forming And Sizing Machine

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.
