The Fully Automatic Anchor Rod Roll Forming Machine is a high-precision fully automatic anchor rod forming equipment designed specifically for mining tunnels, tunnel engineering, and geotechnical support fields. This equipment adopts advanced cold bending and rolling forming technology to continuously process steel strip coils into standardized split set/pipe seam anchors and other types of metal anchors.

This equipment integrates multiple processes such as unwinding, leveling, continuous rolling forming, sizing and straightening, and cutting to length, achieving full process automation and continuous production from steel strip to finished anchor rod. Equipped with advanced PLC control system and human-computer interaction interface, operators can easily set production parameters, and the system monitors the operating status in real time and has fault alarm function. The entire production line has a high degree of automation, and only 1-2 operators are needed to complete full process control.

Application Scenarios：

•  Coal mine roadway support

The stability of the surrounding rock in the coal mining process is directly related to the safety production of the mine. The pipe seam anchor rod can immediately apply radial pressure to the hole wall after installation, and the anchoring force will significantly increase in the later stage under conditions such as blasting vibration and rock anchoring displacement. The anchor rods produced by this equipment are widely used for active support of the roof and side walls of underground coal mine tunnels, and are indispensable support materials for coal mine safety production.

•  Underground support in metal mines

In underground mining operations in metal mines, geological conditions are often more complex and varied. Friction anchor bolts (Split Set) have become the preferred solution for real-time geological stability in modern mines. The pipe seam anchor rods produced by the equipment can be used for various scenarios such as underground mine roof support and surrounding rock reinforcement in the mining area. High quality friction rock anchor rods can effectively reduce the frequency of repairs in underground tunnels.

•  Railway and highway tunnel engineering

The surrounding rock support after tunnel excavation is a key link to ensure construction safety and engineering durability. Hollow grouting anchor rods can be pressurized and grouted from the holes inside the rod body, with better grouting effect than ordinary threaded steel anchor rods, and can effectively control the deformation of surrounding rock. The hollow grouting anchor rod and pipe seam anchor rod produced by this equipment have been widely used in the support engineering of highway and railway tunnels at home and abroad.

Core components of the machine：

This machine is a highly integrated automated production line, mainly composed of the following core components, ensuring efficient and stable output from raw materials to finished products:

1.Uncoiler/Unloading Rack: Used for carrying and stably releasing steel strip coils. Usually it is a hydraulic uncoiler, but some models also use a 3-ton manual uncoiler.

2.Guiding and Straightening Device: Ensure that the steel strip enters the forming area smoothly and stably.

3.Forming Unit: composed of multiple sets of precision designed horizontal and vertical rollers. By continuous rolling, the steel strip is gradually rolled into a circular tube with longitudinal seams.

4.Straightening Device: Accurately control the outer diameter and roundness of the formed anchor rod and eliminate bending.

5.Welding device: uses high-frequency current to weld the longitudinal seam of the anchor rod.

6.Cutting Device: During the continuous movement of the anchor rod, a flying saw or hydraulic shearing device is used for synchronous cutting to a fixed length.

7.Collection Table: Used for collecting and temporarily storing finished anchor rods after cutting.

8.PLC Electrical Control System: As the “brain” of the equipment, it controls the speed and cutting length of the entire line through the PLC system, and monitors the operating status and fault alarms in real time.

9.Hydraulic system: provides power for processes such as cutting and shrinking.

10.Shrinking Machine: Shrinking the end of the anchor rod to facilitate subsequent installation of trays and nuts.

Core advantages：

1. Ultra high molding accuracy, stable and reliable quality

The equipment adopts a precision designed horizontal roller and vertical roller combination forming unit, which gradually rolls the steel strip into a circular tube body and forms a longitudinal slit through multiple continuous rolling passes. Equipped with multiple sets of straightening rollers, accurately control the outer diameter, roundness, and straightness of the formed anchor rod. High molding accuracy ensures high consistency and stability in the outer diameter, wall thickness, length, straightness, and weld quality of the anchor rod – this is crucial for the support performance of the anchor rod.

2. Fully automatic PLC intelligent control, efficient and labor-saving

The equipment is equipped with an advanced PLC control system, which automatically and continuously runs the entire process from unwinding, feeding, leveling, forming, sizing, cutting to discharging. The production parameters (length, quantity, speed) can be conveniently set through the human-machine interface, and the system monitors the operating status in real time and issues fault alarms. Modular system configuration can be combined and matched according to customer needs, and the production line can be configured with a one to one to four production mode. Automated production significantly reduces manual intervention and labor intensity, requiring only 2 people to operate a single production line.

3. High speed continuous production, excellent production capacity

The molding speed of the equipment can reach 0-20 meters per minute. The continuous production method completely abandons the inefficient mode of traditional anchor rod production, which involves multiple machines, multiple processes, and extensive manual collaboration. The production efficiency of a single line can reach 260-300 sets/hour, and the output of a one to two production line can double. From automatic feeding of raw materials, cutting to length, reducing diameter, rolling threads to finished product bundling and stacking, the entire process is continuously operated, greatly reducing the production cycle.

4. Durable and sturdy industrial grade construction

The main frame is designed with a high rigidity structure, the spindle is made of 45 # forged steel that has undergone heat treatment and precision machining, and the rolling mill is made of GCr15 bearing steel or high-grade Cr12 steel. The equipment is equipped with a gearbox transmission system to ensure stable output of high torque. The whole machine can meet the continuous industrial production needs around the clock, with a long service life and low maintenance costs.

5. Integrated molding and cutting to length

The equipment integrates sizing, straightening, and precision cutting units. During the continuous movement of the anchor rod, flying saws or hydraulic shearing devices are used to synchronously complete the cutting to length. Some models can be equipped with a diameter reducing machine to reduce the diameter of the anchor rod end, which is convenient for subsequent wire rolling. High precision cutting ensures consistent product length and a smooth and burr free cut.

6. High material utilization rate and significant cost-effectiveness

The continuous production method minimizes the waste of head and tail materials to the greatest extent possible. Cold bending and rolling technology saves materials compared to traditional cutting technology, while improving material density and anchor rod tensile strength. Standardized production ensures high structural stability of products, reduces defect rates, and significantly lowers overall production costs.
