Square Stirrup Steel Cage Rolling Welding Machine: An Intelligent and Efficient Equipment Precisely Adapted for Square Cage Processing

In infrastructure projects such as municipal utility tunnels, prefabricated buildings, underground garages, and comprehensive utility tunnels, square steel cages are increasingly in demand due to their advantages of high space utilization and stable structural bearing capacity. However, traditional square steel cage processing relies on manual stirrup bending and manual positioning welding, which not only has problems such as large stirrup angle deviation, uneven main reinforcement spacing, and unstable welding quality but also faces industry pain points of low processing efficiency and high labor intensity, seriously restricting project progress and quality. The advent of the square stirrup steel cage rolling welding machine is tailor-made for square steel cage processing scenarios. It reconstructs the processing process through intelligent and mechanized technology, completely solving the traditional processing dilemma and becoming the core preferred equipment for modern square steel cage processing.

Core Advantages: Precisely Adapted for Square Processing, Balancing Efficiency and Quality

• Precise and Controllable Square Processing: Equipped with a customized square positioning mold frame and angle calibration system, it can precisely control the stirrup bending angle (90° error ≤ ±1°), ensuring the square steel cage frame is square and the corners are regular. At the same time, the PLC numerical control system precisely sets the main reinforcement spacing and stirrup spacing (adaptable to 50-300mm stepless adjustment). After processing, the diagonal error of the square cage is ≤ ±3mm, which fully meets the strict requirements of the *Code for Construction Quality Acceptance of Concrete Structure Engineering* for square steel components, completely eliminating the dimensional deviation problem of manual processing.

• Efficient Processing for Significant Production Increase: Integrates full-process automated functions including automatic straightening of square stirrups, precise feeding, main reinforcement positioning, and synchronous welding of intersection points. The traditional manual processing of a 1.2m×1.2m×6m square steel cage requires 6-8 workers to cooperate, taking 4-5 hours; this equipment only needs 2 workers for auxiliary feeding, the processing time per section is shortened to 40 minutes, and it can stably produce 10-12 sections per shift (8 hours), with processing efficiency increased by more than 5 times, greatly shortening the project construction period.

• Flexible Adaptation to Multi-Specification Needs: Adopting a modular design, through quick replacement of square positioning templates and parameter adjustment, it can flexibly adapt to the processing of square steel cages of different sizes from 300mm×300mm to 2000mm×2000mm, compatible with Φ12-40mm main reinforcements and Φ6-12mm square stirrups. The entire process of template replacement and parameter debugging only takes 30 minutes, without the need for overall equipment disassembly, easily coping with the construction needs of multi-specification and small-batch production, and reducing the equipment investment cost for multi-category processing.

• Stable, Reliable, Low-Consumption and Durable: Equipped with special square intersection welding electrodes and intermediate frequency inverter welding power supply, designed with an exclusive welding trajectory for the vertical intersection of main reinforcement and stirrups of square steel cages. The weld penetration is uniform, the firmness is high, and the pass rate of tensile strength test exceeds 99.8%, avoiding quality hazards such as missing welding and insufficient welding. The core components of the equipment are made of quenched wear-resistant steel, and the service life of the welding electrode can reach more than 300,000 times; the intermediate frequency inverter technology reduces power consumption by 40% compared with traditional welding machines, making it more energy-saving in long-term use and significantly reducing operation and maintenance costs.
