Intelligent CNC Steel Bar Threading Machine: Core Equipment for Millimeter-Level Precision Steel Bar Connection
Cold Heading-Threading Integrated Process
Intelligent CNC Operating System
Multi-Scenario Adaptation Technology
As a key equipment for mechanical steel bar connection, the intelligent CNC steel bar threading machine processes steel bar ends into high-precision threaded structures through the cold heading reinforcement and precision threading integrated process. It provides stable and reliable connection solutions for major projects such as bridges, high-speed railways, and prefabricated buildings, and serves as core equipment for realizing the transformation from "manual dependence" to "intelligent autonomy".

Multi-Scenario Adaptation Technology
The innovative three-dimensional constraint structure of "double traction wheels - dynamic limit" effectively reduces the deformation defect rate when processing multiple steel bars simultaneously. It is suitable for full-specification hot-rolled ribbed steel bars with diameters of Φ12-Φ40mm and compatible with international standards such as GB1499 and BS4449. For scenarios where steel bars in prefabricated buildings cannot be rotated, it can accurately process left-hand/right-hand threads. Cooperated with double-threaded sleeve, it realizes rapid connection within 30 minutes, and the efficiency is 4-10 times higher than that of traditional processes.
Performance Parameters | Data Indicators | Industry Comparative Advantages |
Processing Efficiency | 40 seconds per thread head, 400-600 pieces per shift | 5 times higher than manual processing |
Dimensional Accuracy | Thread error ≤ ±0.02mm | Meets millimeter-level construction requirements |
Equipment Energy Consumption | Rated power 30Kw | 15% more energy-efficient than traditional equipment |
Raw Material Loss | ≤1.2% | 60% lower than the industry average |
Operation Rate | 97% | Far exceeding the 60% benchmark of manual operation |
III. Application Scenarios and Project Cases
Major Infrastructure Field: At the Nanyanzhuang Beam Fabrication Yard of the Xiong'an-Xinzhou High-Speed Railway, it is linked with the intelligent steel cage workstation to realize the integrated operation of threading and welding for the longitudinal bars of U-shaped steel cages, shortening the processing cycle of a single box girder to less than 4 hours.
Prefabricated Building Field: It is suitable for the connection of prefabricated beam and shear wall steel bars. Cooperated with double-threaded sleeve technology, it solves the problem of steel bar radial deviation and has been applied to benchmark projects such as Xiong'an High-Speed Railway Station.
Bridge and Tunnel Engineering: It processes the threaded ends of pier body and cap beam steel bars. The joints have passed 2 million fatigue tests and are suitable for high-strength demand scenarios such as cross-sea bridges and tunnel linings.
