High Frenquency Welded Pipe Production Line for Large Diameter Pipe Specification

High Frenquency Welded Pipe Production Line for Large Diameter Pipe Equipment Composition

Uncoiler

1. Single expansion and cantilever mandrel.

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

3. Equipped with a pneumatic system to meet the needs of expansion, contraction and braking of the mandrel.

4. The mandrel is composed of a four-bar linkage mechanism, which can move radially at the same time.

5. Two sets of four-bar linkages are installed on two shafts respectively. They are powered hydraulically, expanding and contracting radially.

Straight machine

1. This equipment is used to smoothly guide the steel strip into the leveling machine.

2. It consists of pressing arm and shovel head. Gantry type upper and lower uncoiler.

3. Compression arm cylinder: Φ160, compression arm guide cylinder: Φ90.

Compression arm motor: 2.2kw, 380V, 60Hz.

Pinch leveling part

1. This machine is used for leveling the head and end of strip steel, which makes cutting and welding easy.

2. Leveling motor: 11KW

3. Pinch roller diameter: Φ210x800mm, roller material: 40Cr,

4. Diameter of leveling roller: Φ140x800mm, roller material: 40Cr,

5. Leveling width: 240-640mm

6. Clamping/leveling thickness: 2.0-6.5mm

7. Clamping/leveling speed: 0-11M/Min

Hydraulic part

It is a hydraulic system for the preparation step equipment of the tube rolling line (uncoiler, leveler, shear welder) and ensures the control of the above equipment processing by hydraulic fluid.

Semi-automatic cutting machine

Spiral looper

1. The machine is located between the shear welding machine and the main machine (forming and sizing machine). diameter machine) continuous production and storage of sufficient strip time.

2. This device mainly includes pressure feeding device, accumulator assembly, feeding device and electric control device.

Ballast material device

Pressure feeding device: mainly includes frame, motor, brake device, transmission power shaft in the direction of deceleration and rotation, pressure feeding roller, guide roller pressure air system, and speed inspection device; it can supply the strip steel to the accumulator, and at the same time convey The speed information is transmitted to the electrical control system, when we request to stop feeding the material to the unit, it will stop rolling to the motor, and press the material roller by interruption, and also adjust the speed of the feeding motor and the speed of the unit feeding the material.

Accumulator frame assembly

Accumulator frame assembly: including motor, frame, inner ring roller, outer ring roller and pressure roller. It can be used to store strip material from the ballast unit, or it can be picked up from the center feed roll.

Feeding device

Feeding device: including rack, guide roller, high or low guide roller. It can convey the strip steel to the forming system, and send the conveyed material speed information to the electronic control device.

Forming and sizing part

1. Rough forming (decomposition, clustering): feed flat roller, feed, feed, five-roll passive leveling, horizontal, horizontal, vertical, horizontal, vertical, vertical

2. Fine forming (fin pass) horizontal, vertical, horizontal, vertical, horizontal, vertical

3. Welding table: guide roller, four-roll extrusion, mechanical scraping, polishing roller.

4. Cooling water meter

5. Sizing machine: vertical, hexapod, MR, two sets of turkey heads

Computer saw

The pipe cutting machine is the key equipment for the production of pipes, which is used to automatically and accurately cut various frame pipes. As far as the use of high-precision STD control system and mechanical system is concerned, this unit has a good advantage of precise size, and the best advantage of mechanical transmission, so fast ability and precise processing are the advantages of this unit.

The main unit includes frame gearbox, cutting machine, press machine, speed detection device, hydraulic system, drive system, electrical system, roller frame, a total of 9 components.
