5. Main machines

 

 

5.1 Uncoiler

Structure: The double work station decoiler, it is manual rotary type and double work station manual harmomegathus. It contains two main parts: main body and the fixed base. The main body is equipped with expanding and contracting system, braking of the mandrels, one cone is working and the other is preparing, then turn 180°to work.

 

Parameters:

 

Strip width: 60-200mm

 

Coil OD: Φ1500mm

 

Coil weight: 0.5-2.0MT

 

5.2 Shear/end welder

In the shear/end welder the ends of the coils are cropped, precisely aligned and welded together in the shortest possible time.

 

Shear form:

Manual guillotine shear

Welding form:

Pneumatic material platform, Manual welding with CO2 gas shield welder

 

5.3 Two rollers delivery machine

It is mainly gantry type frame, the lower roller drive, equipped with guidance vertical rollers and horizontal material pressure rollers. It can deliver the after welded steel strips into the material collecting box, maintaining enough material in material accumulator.

 

 

 

5.4 Cage type accumulator

 

A continuous production process is ensured by accumulator, which bridges the standstill time in the strip preparation section during the welding of the coil ends. The structure is overall frame type, made of fixed frame, activity frame, and strip support rollers and tension rollers. It is adjustable freely based on the strips width.

 

Parameters:

 

Allowed stripes width

60-200mm

Stripes thickness scope

1.0-3.0mm

The feeding speed

Max. 90m/min

The filling speed

Max. 160m/min

Stored length

600-800m

 

 

 

 

 

 

 

 

 

 

 

 

 

 

5.5 Forming and sizing machine

 

This machine 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.

 

 

 

Structure: forming section, sizing section, guiding device, squeezing rollers, outer scraping, water cooling, and turkey heads.

 

Stands no.:

 

Feeding section: 1 level roll stand, 1 guiding side roll stand, 1 five-roll straighter.

 

Forming section: 7 level roller frames, 8 vertical roller frames;

 

Sizing section: 6 level roller frames, 5 vertical roller frames, 1Turk’s head

 

 

5.6 Computer control flying saw

 

Computer control flying saw is used for cutting tubes to length in the line. It is mainly consists of lathe bed, gears, rack cabinets, saw car, clamps, speed measurement system, driving system, electrical system, carrier rollers and so on.

 

Parameters

 

 

 

Cutting pipe outer diameter:

Round pipes Φ38mm-Φ63mm

 

Square pipes: 30×30-50×50mm

Rectangular pipes: 25×50-40×60mm

Cutting wall thickness

1.0-3.0mm

Cut length:

6m

Cut accuracy:

±3mm

Saw cutting number of times:

Max. 15per minute

Max. 90m/min

 

 

5.7 Pipe Output conveyor and packaging machine

The pipe output conveyor consists of runway, reverser, and pipe bench.

Runway: is used for conveying the finished pipe from flying saw to the packaging machine.

Reverser: it is an auxiliary device, can achieve carrying the pipe from runway to the bench by its turnover mechanism.

Pipe bench: A carrier for temporarily storing steel pipes on it in order to leave times for packaging pipes.

Packaging machine: can be hydraulic or manual type.
