Feature And Application

1.The X15 Box beam welding lines are high automation production lines to produce the welded Box beam columns with lesser workers and lesser cranes.
2.The line can be fully integration with the MES system and complete the real-time communication between the upper computer and the control system, complete the data collection of the equipment, upload all collected data to the factory MES system (or the upper centralized control system), and ensure the timeliness and effectiveness of information transmission.
3. The design and protection must meet the requirements of relevant national standards and environmental protection; Equipment safety and protective devices must meet relevant industrial standards;.
4.This Box beam welding lines are widely used in steel construction and steel structures, for welding Box beam columns for steel construction building, high level building and steel structures, or bridges etc. 
5. The flexible design of the welding equipments allow to support any brands of the welding power sources.
6. CE, ECA certificated are available.
7. This line provide the production from light duty beam to very heavy duty beam with big thickness without changing any tools or equipments.
8. From the assembling to the end-facing the whole processing no need any cranes except the loading at the beginning and unloading in the end, which reduce greatly the risk of using cranes.

The list of the machines and equipments to established a whole production line to produce welded box-beam:

1-Baffle assembling machine
This machine is a special equipment for the assembly and positioning welding of the reinforcing rib plate in the inner cavity of the box beam. It is the preferred product for steel structure enterprises that produce the box beam workpiece to reduce labor intensity and improve work efficiency.


2-Box-beam assembling machine
The box assembly machine is the key equipment for the production of box beam (column), which mainly completes the assembly of box beam (column) workpiece. This machine is one of the necessary equipment for steel structure enterprises to produce box girders.
One machine for U type assembling.
One machine is for Box type assembling.


3-Electro-slag welding machine
XZHB15 cantilever electroslag welding machine is an excellent product launched by Jinfeng Welding and Cutting Company for the steel structure industry. It is a special welding equipment specially designed for welding box beam. In order to ensure sufficient rigidity and torsion resistance during box beam fabrication, baffles (i.e. stiffer plates) are generally welded on the inside of the box beam. This machine is a special equipment for welding the welds between the outer plate of the box beam and the inner baffles.


4-CO2/MAG back welding machine
XQHB15L series box beam cantilever gas shielded welding machine is a special welding equipment specially designed for backing welding of box beam (column) and filling welding after backing, which is launched by our company based on market demand and years of experience in developing steel structure equipment.

5-CO2/MAG filling welding machine
XQHB15 series box beam cantilever gas shielded welding machine is a special welding equipment specially designed for backing welding of box beam (column) and filling welding after backing, which is launched by our company based on market demand and years of experience in developing steel structure equipment.
 
6-Submerged arc welding machine
XMHB15 box girder cantilever submerged arc welding machine is an excellent product launched by Jinfeng Welding and Cutting Company for the steel structure industry. It is a special welding equipment specially designed for welding large and medium-sized box beams (columns). Over the years, after continuous optimization and improvement, the performance has become more perfect.

7-End-face milling machine
With the rapid development of economic construction, construction, bridge and other industries have increasingly strict requirements for the quality of steel structure engineering. The butt joint of H-beam, box beam and column, and slender parts, and the end face processing of the workpiece have become an essential process. The end face processing not only greatly improves the quality of the workpiece, reduces the on-site installation and construction errors, shortens the construction period, and improves the on-site construction efficiency. It also brings better economic benefits to steel structure enterprises. According to the actual processing situation of steel structure enterprises, our company is absorbing the advantages of similar products internationally, and timely launched new products to meet the market demand. It is not only used in the steel structure industry, but also can be used as general equipment, widely used in bridge, electric power, oil, petrochemical and other machinery manufacturing industries.


8-Beam flipper 180°overturn
Two pieces of mobile 180 ° hydraulic beam flippers are used for turn-over of workpieces welded on one side. When working, lift the workpiece away from the roller table or work-piece rack, and the reducer drives the two beam flippers to move synchronously to move the workpiece to the side of the roller table or work-piece rack, and then two hydraulic cylinders drive the two arms to rotate synchronously, move the workpiece to the middle of the roller table or work-piece rack after overturning, and then transport the workpiece to the next process or welding.
According to the actual situation, two pieces can be used separately as a group to flip the short beam. At the same time, 4 pieces can also be combined into one group for the overturning of long beams. High flexibility and efficiency.


The working flow chart of beam flippers:

9-Steel cart
This equipment is mainly used to coordinate with the production process to move the workpiece from the conveying roller table or other equipment to the equipment to be processed. The steel cart mainly has two action functions: walking and lifting. The displacement of the workpiece can be completed through manipulation and control. The equipment has simple structure, convenient operation and stable operation. The machine adopts heavy-duty design, with a maximum load of 30 tons;


10-Roller tables
It is mainly used for conveying workpieces from the assembly of box beam to the completion of welding, end facing.
