The high level of automation and continuous production feature of the cold-rolled ribbed steel bar mesh production line, as well as the superior strength and standardized characteristics of the finished products.
The core advantages of cold-rolled ribbed steel bar mesh are indeed concentrated in the production process and product performance. On the production line, high automation is mainly reflected in the raw material processing, welding forming, and quality control stages. For example, automatic unwinding and straightening of wire rods, robot welding, visual inspection systems, and other continuous flow operations. The key to continuous production lies in eliminating the process breakpoints in traditional steel bar processing and achieving a seamless transition from wire rods to finished mesh sheets.
The high-strength characteristics of the product are worthy of detailed discussion: Cold working hardening increases the yield strength by more than 40%, and rib patterns enhance the grip force of the concrete, which is more suitable for modern high-rise building requirements than hot-rolled steel bars. The advantage of standardization is reflected in the consistency of standardized mesh sizes and weld strength, directly leading to an increase in construction efficiency and a reduction in losses.
Highly automated and continuous production features
1.Raw material processing automation:
Automatic unwinding and straightening: The wire rod (wire) is unwound through an automatic unwinding machine, and the original bending of the wire rod is eliminated by an efficient straightening machine, achieving continuous and stable material supply.
Automatic feeding and fixed length: The precise feeding mechanism driven by servo or hydraulic power, combined with high-precision encoders or laser distance measurement, realizes the precise cutting of the reinforcing bar to the fixed length.
2.Cold rolling forming automation:
Automatic cold rolling forming: After fixed-length cutting, the reinforcing bars automatically enter the cold rolling unit. The rolling machine is usually composed of multiple passes of rolls (long rib rolls, short rib rolls), and continuously undergoes rolling deformation at room temperature.
Online monitoring and adjustment: The rolling process parameters (pressure, speed, temperature compensation) are automatically controlled by PLC and monitored in real time, ensuring consistent rib size (height, spacing, angle) and surface quality. Sensors (such as diameter gauges) can provide real-time feedback for fine-tuning.
3.Welding and forming automation:
Automatic netting and positioning: The rolled longitudinal reinforcing bars (with ribs) and transverse reinforcing bars (usually plain round or ribbed wire) are automatically and precisely arranged to the netting formation position.
Fully automatic resistance welding: Using high-precision resistance welding machines (usually multi-head welding machines). The welding parameters (current, voltage, time, pressure) are precisely set and optimized by the control system. The electrodes are automatically positioned, pressurized, energized, cooled, and complete the welding of each weld point.
Robots or dedicated mechanical hands: In more advanced lines, industrial robots may be used to complete tasks such as netting, movement of
welding heads, or transfer of finished products.
Finished product handling and palletizing automation:
Automatic cutting/spacing: The continuous welded large sheets of net are automatically cut or separated into individual net pieces according to the set dimensions.
Automatic palletizing/strapping: The finished net sheets are neatly stacked by the mechanical hand or the automatic conveying and stacking system, and may be automatically strapped and fixed for easy transportation and lifting.
Continuous production process:
From the unwinding of wire rods to the final packaging of the finished products, the entire production process is completed on a highly integrated production line, with each process closely connected.
It eliminates the frequent material transfer, waiting and manual intervention steps that are common in traditional manual binding or semi-automatic processing.
The production rhythm is stable and smooth, significantly improving the equipment utilization rate and production efficiency.
