Working Principles and Applications of CNC Steel Mesh Welding Production Line
With the development of the economy and the improvement of the level of industrialization of construction, the adoption of new technologies and new processes in the construction industry has shown rapid changes.
The traditional manual tying of steel bars in building construction has been difficult to meet the needs of the current rapid development of construction projects due to the slow construction speed, the difficulty of quality assurance, the large consumption of materials, and the large loss of edge materials. The CNC steel wire mesh welding production line replaces manual tying of steel bars with its unparalleled advantages, which is an inevitable development of the construction industry.
1. Working principles of CNC steel wire mesh welding production line
The CNC steel wire mesh welding production line can adopt automatic straightening, automatic feeding, automatic welding, automatic cutting, and automatic cutting. The whole process requires only one worker for operation. The welding principle is resistance welding. This kind of welding has small weld scars. It has the characteristics of firmness and non-deformation.
Resistance welding refers to the method of using the resistance heat generated by the current passing through the weldment and the contact point as the heat source to locally heat the weldment while applying pressure for welding. When welding, no filler metal is required, the productivity is high, the deformation of the weldment is small, and it is easy to realize automation.
2. Application and advantages of CNC steel wire mesh welding production line
Welded steel wire mesh is a high-strength, high-efficiency construction material for concrete reinforcement. It is used on a CNC steel wire mesh welding production line, and the vertical and horizontal steel bars required for the design are equidistantly or perpendicularly arranged according to the distance set by the program. All the intersections are welded with steel wire mesh by resistance spot welding. It is used in the fields of floor slab, floor, shear wall, road pavement, bridge deck paving, box culvert, dock floor, prefabricated component and so on.
Save steel consumption
Welded steel wire mesh is made of low-carbon hot-rolled wire by cold-drawn or cold-rolled processing. The tensile strength of the wire is increased to above standard, so the amount of steel can be reduced. In addition, the loss of the steel mesh on the CNC steel wire mesh welding production line is minimal.
Improve engineering quality
The welded steel wire mesh is manufactured by an automated production line in accordance with the internationally-used design and technology. The production process is strictly controlled by quality. The quality requirements such as mesh size and steel bar specifications can be effectively controlled. There will be no situations such as site personnel bundling omission, bundling error or cheating on workmanship and materials, so as to improve the quality of the project.
Improve crack resistance
The manufacture of the CNC steel wire mesh welding production line is carried out after rigorous calculation and check, and then accurately arranged according to the design specifications. Then, the current is applied to make the intersection of the composite vertical and horizontal steel bars. The entire mesh is uniform in size, and the stress transfer is uniform, and the load can be evenly spread on the entire concrete structure to prevent cracks from occurring. According to actual test results, paving steel mesh on roads can reduce the occurrence of cracks by more than 75% compared with not laying steel mesh.
As a new type of construction material, the cold-rolled ribbed steel production line and the CNC steel wire mesh welding production line will be widely used in the construction industry, so as to improve the industrialization level of steel engineering, and obtain good economic and social benefits.
