Metal rock bolts making machine 5 Lines Strong Setup
A Metal rock bolts making machine consists of five independent production lines. Each line handles a different processing task, so the hydraulic power, transmission, and electrical setup vary across the equipment. Understanding these setups helps you judge whether the whole line matches your production needs.
Applications of Split Set Rock Bolts
Split Set anchor rods are mainly used for mine roadway roof and side support, highway and railway tunnel primary support, and slope treatment and geological hazard prevention.
A complete anchor rod needs four core steps: pipe body, dome plate, ring, and welding. A Metal rock bolts making machine uses the roll forming line for the pipe body, the press line for the dome plate, necking for the pipe end, ring making for the ring, and welding to combine the parts.
Power and Transmission of Core Production Lines
Different processing actions need different power demands. It's helpful to know the setup of the core lines.
Power and Transmission of the Roll Forming Line
A Metal rock bolts making machine cold bends steel strip into the pipe body. It uses a 15 kW drive motor and gearbox transmission. Forming speed is 0 to 15 m/min, material thickness is 2.5 to 3.5 mm, and pipe outer diameters are 39 mm and 46 mm.
A 7.5 kW hydraulic station powers notching and shearing. At the set length, the hydraulic stop shearing system cuts the pipe and makes a notch simultaneously. The heavy duty cast steel frame with middle plate welded base supports continuous cold forming.
Power Setup of the Dome Plate Press Line
The dome plate press line handles simultaneous punching and forming on thick steel plate. It uses a 15 kW hydraulic station at 380 V 60 Hz 3 phase. Processing speed is 0 to 10 pieces per minute. The mold material is Cr12MoV, handling material thickness of 5.0 mm.
Setup of the Necking, Ring Making, and Welding Lines
The necking line uses a 3 kW hydraulic motor for local necking. The ring making line uses a 2.2 kW motor to bend 6 to 8 mm wire at 40 to 45 pieces per minute. The welding line uses TIG Model 350 for rods of 28 to 50 mm diameter and 1.2 to 2.8 m length.
Technical Parameters of the Five Line System
Parameters for this Metal rock bolts making machine are listed by line. Roll forming, necking, and ring making use 380 V 50 Hz. Dome plate press and ring welding use 380 V 60 Hz.

Advantages of the Five Line Setup
The five line design of this Metal rock bolts making machine delivers clear operational advantages:
-
Task matched power: Each line uses a drive and hydraulic setup tailored to its specific processing workload.
-
Independent management: Separate hydraulic and electrical systems allow you to troubleshoot and maintain each line without affecting the rest of the workflow.
-
Grid flexibility: The equipment accommodates different voltage and frequency requirements to match your local power supply.
-
Process integration: The five independent lines work together to cover the full production flow from steel strip to finished rock bolt.
This modular setup simplifies daily operations and keeps maintenance focused on the specific line that needs attention.
