Digitally controlled Spiral welded pipe mill

Spiral welded pipe mill is used to produce spiral welded pipe equipment. The steel pipe is transformed into a spiral steel pipe by a molding machine, and the steel pipe is welded by a submerged arc welding machine.

Spiral welded pipe mill needs to adjust the molding machine when changing steel pipe specifications. This is a very hard work, dirty and tiring, and requires a very experienced skilled worker to complete the work. Because, if the adjustment is wrong, it will produce a large number of waste steel pipe, and even can not produce qualified steel pipe.

After years of research and development, our company finally invented a digitally controlled Spiral welded pipe mill.

The adjustment of this Spiral welded pipe mill is based on database + computer automatic control technology. Spiral welded pipe mill in the transformation of specifications need to adjust the molding machine 6 composition roller, the former adjustment work done by experienced adjustment workers, there is no theoretical data, relying on the adjustment of the experience of workers, this easily lead to an adjustment is not in place , waste management more. The adjustment and position of the six-component rollers of our Spiral welded pipe mill are precisely controlled by the encoder, and a complete database is established in advance based on theoretical data. When producing steel pipes of a certain specification, only the computer database is required. Select parameters such as plate width, pipe diameter, and wall thickness, and the 6-concrete roller will arrive at the correct position on its own and start production directly. This reduces adjustment efforts, reduces reliance on experienced adjustment workers, and reduces waste management. Of course, due to the complexity of the equipment, the data in the database may not be completely suitable. Therefore, the equipment design has fine-tuning functions and database correction functions. After a certain type of adjustment is appropriate, the database can be corrected, and the production can be directly performed when it is produced again.

Advanced Slitting line

Our company’s Slitting line has many advanced technologies and advantages

1. automatic decoiling machine centering technology:

Our company’s Slitting line uses the automatic centering technology of the unwinder to automatically center the coil onto the centerline of the unit after the coiler is loaded with coils. The alignment of steel coils is very important for the slitting unit, which directly affects the normal operation of the unit. If it is not aligned, it needs to be adjusted during the working process, and even serious accidents such as burr stripping and coiling deflection may occur. The unit’s parking adjustment greatly affects the unit’s production efficiency. If there is no automatic alignment technology, the pairing will become very difficult, and relying on artificial alignment will always result in inaccurate alignment and affect the normal production of the unit.

2.rapid unwinding technology:

Our company’s Slitting line uses a quick unwinding technology to quickly disassemble the head of the coil and send it to a pinch leveler. The speed of unwinding is very much related to the blade. The machine adopts a blade with a roller. After the blade opens the steel roll, the roller lifts and holds the steel belt, and the blade is separated from the steel belt. This solves the problem of dismantling. The problem that the steel belt is not easily transported forward makes the unwinding very easy and smooth, and improves the unit efficiency.

3. waste edge fast unloading technology:

Our company’s Slitting line uses a waste edge quick discharge technology, which can easily remove the wrapped scraps and eliminate the need for crowbars to unload.

4.head, tail bending technology:

The thick-walled and high-strength plate heads are not easy to bend and take up. When unloading, it is easy to get caught in the take-up shaft; the tails of the plates are not easy to pack and the bags are easy to collapse. Our company designed this company’s unique head and tail bending mechanism to solve this problem effectively.

5. rapid introduction of steel strip separator technology:

Our company’s Slitting line adopts a steel strip quick-introducing separator technology, which can adjust the position of a steel strip that is not slit and can not correspond to a separating piece. However, the slitting line can be quickly introduced into the separating piece without using a manual crowbar to increase the weight. Way to import. Improve the efficiency of the unit, reduce labor intensity and reduce the hidden dangers of work-related injuries. This device is provided on both the tensioner and the coiler, so that the strips of the slitting machine are guided into the separators very smoothly and no manual intervention is required.

6.safe follow-up pit cover technology:

Our company’s Slitting line employs a follow-up pit cover technology, which solves the problem that workers can easily fall into the pit when packing work at the coiler. The unloading car comes with a pit cover, and the pit cover is connected to the body of the unloading trolley and moves along with the movement of the vehicle body. When the unloading trolley comes under the winding shaft, the pit cover can be Cover the pits of the unloading trolleys on the outside to facilitate the passage of workers and avoid accidents at work.

7.visual recognition intelligent adjustment of steel strip deviation control system

When the Slitting line is working, due to burrs and other reasons, the steel strip will produce running deviation phenomenon, if serious, it will cause shearing and affect the product quality. The current response is to manually look at the size of the side of the wire. If the deviation is serious, adjust the vertical roller manually to avoid shearing. However, due to the slower artificial response, in order to ensure product quality, the shear rate is often reduced, resulting in low production efficiency. The intelligent adjustment system newly developed by our company’s Slitting line can improve production efficiency without manual observation and adjustment. This system uses a visual recognition system to observe the deviation of the steel strip. It can automatically determine the deviation degree of the steel strip, intelligently analyze and adjust the timing, and automatically send out adjustment signals to drive the vertical roller to adjust the steel strip to ensure the center of the steel strip. The working speed of the slitting can be increased, so that the production efficiency can be improved and the product quality can also be effectively guaranteed.
