n recent years, numerous small‑bridge, municipal pipe network, foundation pit support and small‑scale water conservancy projects have been carried out across many regions. For these foundation‑pile‑related construction works, small‑diameter steel cages are essential core components. In the early stage of construction, most projects adopted traditional manual binding and welding methods to produce steel cages. This old‑style working mode has obvious defects. Manual operation leads to unstable forming accuracy, inconsistent welding quality, heavy workload, large labor input and low production speed, which cannot well match the tight construction schedule of modern projects. Against this background, the 800 Small‑Sized CNC Steel Cage Roll Welding Machine has gradually become popular on various construction sites.
The 800 Small‑Sized CNC Steel Cage Roll Welding Machine is professional automatic equipment for processing small diameter reinforcing steel cages, which is widely used in small bridge construction, municipal pipe network engineering, foundation pit support, small water conservancy and other foundation pile projects. The equipment integrates steel bar feeding, spiral stirrup winding, automatic welding and precision forming functions, with compact floor space, convenient movement and simple operation, which can completely replace traditional manual binding and welding operations.
This machine realizes precise forming and stable welding performance. Adopting precise roll welding positioning technology, the steel cage diameter error is ≤±5mm, length error ≤±10mm, regular forming. The automatic welding system realizes uniform, full and cold‑solder‑free welds, the welding strength meets national engineering standards, effectively avoiding missing welding and cold welding problems caused by manual operation, and ensuring the structural stability of steel cages.
It brings prominent advantages of high efficiency and labor cost reduction. Automatic roll welding replaces manual binding and welding, the processing efficiency is more than 6 times higher than traditional manual work. A single 800mm diameter, 12m long steel cage can be finished within 40 minutes, the daily output can reach 20‑30 pieces. It only needs 2 operators, replacing 4‑6 manual workers, greatly reducing labor intensity and shortening construction period.
This welding machine owns strong adaptability and wide application range. It can process steel cages with diameter 260‑800mm and length 12m, longer size can be customized. It can flexibly adjust the diameter, length and stirrup spacing of steel cages, adapt to different specifications of main bars and stirrups, meet diversified processing demands of various construction projects, with strong versatility. Its main technical parameters are as follows. Applicable cage diameter ranges from φ350‑φ800mm, 260mm is customizable. Max cage length reaches 12m, size over 12m can be customized. Main bar diameter supports φ16‑φ40mm customizable. Spiral bar diameter is φ6‑φ12mm customizable. Spacing of stirrup can be ≤300mm. Hydraulic pressure is ≤16MPa, air pressure ≤0.8MPa. It adopts side‑mounted double‑gun welding mode. The total power is 60KW and welding power is 30KW. Normally 2 persons are required for operation. Its production capacity can reach 8pcs per 10 hours for 12‑meter‑long cage. The occupied area is 28m×5m.
