A Split Set anchor rod is a full column friction rock bolt. It is roll formed from high strength steel strip into a longitudinally slotted tube. After installation, it provides support through radial friction between the tube wall and the borehole wall. These rods are widely used in metal mines for stope and roadway wall support.

To produce them consistently, you need a complete production line. The Anchor Rod Forming Machine gives you that capability with five independent lines that handle every step from steel strip to finished bolt.

Common Application Areas

Split Set anchor rods serve many underground support applications:

• Mine roadway roof and side support

• Highway and railway tunnel primary support

• Dam slope and reservoir bank reinforcement

• Underground cavern and foundation pit support

• Slope stabilization and geological hazard control

Mining support suppliers and tunnel contractors are the two main customer groups for these products. If you supply to these industries, you need production equipment that delivers consistent output, minimal downtime, and low per unit cost. The Anchor Rod Forming Machine is built for exactly these demands.

Anchor Rod Forming Machine Production Line Advantages

Five lines work independently. The line consists of five separate machines. Each machine has its own power, control, and work area. When one machine requires maintenance, the other four can continue operating. This design helps prevent full line shutdowns.

Heavy duty frame structure. The main machine uses a cast steel frame with a welded middle plate base. This structure absorbs vibration during forming. It also helps maintain accuracy over many years of operation.

Gearbox drive system. The machine uses a gearbox instead of a chain drive. Gearbox drives typically run smoother and quieter. They also tend to have fewer issues under sustained heavy loads, which can reduce drive system related downtime.

Hardened rollers and molds. Rollers use Cr12 steel with quenching treatment. Necking and ring making molds use GCr12. Dome plate molds use Cr12MoV. These materials are selected for wear resistance, which helps reduce the frequency of mold changes and supports longer production runs.

PLC control with recipe storage. The machine includes a Delta PLC control system with a multilingual interface. Operators can save multiple product recipes and switch between them with a few touches. This reduces setup time and lowers reliance on highly skilled operators.

Complete Manufacturing Process for Anchor Rods

A Split Set anchor rod goes through five steps from steel strip to finished product. Each step uses a dedicated machine.

Step 1: Pipe body forming. The Split Set Roll Forming Machine gradually cold forms steel strip into a longitudinally slotted tube. It runs at 0 to 15 meters per minute, handles 2.5 to 3.5 mm material thickness, and supports 39 mm and 46 mm outer diameters.

Step 2: Dome plate stamping. The Split Set Dome Plate Press Machine punches holes and presses the dome plate shape simultaneously. Maximum material thickness is 5.0 mm.

Step 3: Pipe end necking. The Split Set Necking Machine reduces the pipe end diameter to fit the dome plate. Hydraulic motor power is 3 kW. Molds are GCr12.

Step 4: Ring making. The Split Set Ring Making Machine bends wire into fixing rings at 40 to 45 pieces per minute. Wire diameter is 58 mm.

Step 5: Final assembly welding. The Split Set Ring Welding Machine joins all components into finished rock bolts using TIG welding. Power rating is 350. It handles pipe diameters from 28 to 50 mm.

Material Specifications and Processing Range

The Anchor Rod Forming Machine supports various material specifications to meet different application needs.

• Pipe material: carbon steel or high strength steel strip (customer supplied)

• Pipe thickness: 2.5 to 3.5 mm (adjustable)

• Pipe outer diameter: 39 mm or 46 mm (change molds)

• Dome plate thickness: up to 5.0 mm

Flexible Purchasing and Configuration Options

The five lines run independently, which gives you purchasing flexibility.

Step by step purchasing. Start with the ring making and welding lines. Buy pipe and dome plates from other suppliers, assemble finished rods, and generate revenue before adding more lines.

Individual machine selection. Add only the machines you need for specific production steps. Each machine runs independently and works with existing equipment.
