Rebar threading machine

A rebar threading machine is a key piece of equipment in infrastructure engineering for the mechanical connection of rebars. It is mainly used for threading the ends of round and rebar bars, providing precise threads for the connection between the rebar and the sleeve. The equipment adopts a motor-driven + gear transmission structure, equipped with high-strength alloy thread rolling wheels or dies. The machine body is constructed of welded steel or cast iron, ensuring high stability. Based on the degree of automation, it is divided into semi-automatic and fully automatic models. The fully automatic model is equipped with a CNC feeding, automatic clamping, automatic threading, and thread detection system. Thread specifications, length, and processing speed can be set via a touch panel. It supports processing Φ12-50mm rebar and round steel, with thread accuracy reaching 6g level and thread length error controlled within ±0.5mm. Compared with traditional manual threading, it has advantages such as high processing efficiency, stable thread quality, and low labor intensity. It solves the problems of poor accuracy and inconsistency in manual threading and is widely used in rebar connection operations in bridges, high-rise buildings, subways, tunnels, and other projects. It is a core piece of equipment for achieving standardized mechanical rebar connections.

Feature

1. Excellent Threading Accuracy: Utilizing precision gear transmission and CNC positioning, the thread accuracy reaches 6g level, with full and uniform thread profiles and a clearance of ≤0.1mm between the thread and sleeve, ensuring connection strength.

2. High Processing Efficiency: The fully automatic model completes the threading cycle of a single Φ25mm rebar in only 15-20 seconds, processing 1000-1500 rebars in 8 hours, which is 4-6 times more efficient than manual threading.

3. High Degree of Automation: The fully automatic model automates the entire process from feeding, clamping, threading, tool retraction, and unloading. Some models support continuous processing of multiple rebars, significantly reducing manual intervention.

4. Wide Compatibility: It can process rebars of different specifications from Φ12-50mm. By changing the thread rolling wheel or die, the thread type can be switched (e.g., M14-M56), meeting various connection requirements. 5. Highly Durable Cutting Tools: The thread rolling wheels are made of Cr12MoV alloy and vacuum-hardened. A single set of thread rolling wheels can process 5000-8000 Φ25mm steel bars. They can be repaired and reused after wear, reducing consumable costs.

6. Convenient and Intelligent Operation: Equipped with a touchscreen human-machine interface, preset parameters for commonly used steel bar specifications, and supports parameter storage and retrieval. Semi-automatic models use a foot switch for control, allowing beginners to operate the machine proficiently within one hour.

7. Comprehensive Safety Protection: Features overload protection, an emergency stop button, a protective cover, and anti-accidental contact devices to prevent steel bar swinging or cutter injuries, complying with the "Safety Technical Regulations for the Use of Construction Machinery."

8. Stable and Reliable Structure: The machine body is made of integral casting or thick steel plate welding, providing high rigidity and good shock resistance. Key components use precision bearings, resulting in minimal accuracy degradation over long-term operation and a low failure rate.
