The Zhongtuo Anchor Bolt Roll Forming Machine is a professional cold forming solution designed for manufacturing split set rock bolts, friction stabilizer tubes, and related metal anchoring components used in mining, tunneling, and underground construction.
This equipment is developed to support stable production, consistent profile forming, and efficient manufacturing of steel rock support components. With a robust machine structure, precision forming rollers, reliable mechanical transmission, and customized production arrangements, the machine is suitable for manufacturers of underground ground support products.
Zhongtuo can also provide a complete Split Set Rock Bolt Production Line, including the roll forming machine, dome plate press, necking machine, ring making machine, and ring welding machine.
Precision-designed forming rollers gradually transform metal strip into the required split set rock bolt cross-section. Proper tooling design and machine adjustment help maintain consistent profile dimensions during continuous production.
The heavy-duty machine frame provides structural stability during operation. High-quality mechanical components and a suitable drive system support reliable industrial manufacturing.
The machine is designed with practical operating arrangements and accessible components to simplify routine inspection, operation, and maintenance. Control functions can be configured according to the selected production system.
Different mining and construction projects may require different rock bolt dimensions and material specifications. Zhongtuo provides customized forming equipment and tooling solutions based on customer requirements.
The equipment can be configured with suitable electrical control components, drive motors, gearboxes, and hydraulic systems according to the required production process.
A split set rock bolt, also known as a friction rock stabilizer, is a steel ground support component commonly used in underground mining and tunneling applications.
The split set bolt typically features a longitudinally slotted tubular structure. It is designed to develop frictional resistance when installed in a suitably sized borehole, helping provide support to surrounding rock.
Split set systems may also use compatible bearing plates and retaining rings depending on the required installation arrangement.
The required bolt dimensions, material properties, installation specifications, and support capacity must be determined according to engineering design and applicable mining safety requirements.
Zhongtuo offers integrated equipment solutions for the manufacturing of split set rock bolts and related anchoring components.
The complete manufacturing system can include five major machines, each performing a specific operation in the production process.
The Split Set Roll Forming Machine is the core equipment used to manufacture the slotted tubular body of the rock bolt.
Metal strip passes through multiple forming roller stations and is gradually bent into the specified open-seam tubular profile.
The machine uses a heavy-duty steel structure to support the forming stations and mechanical transmission system.
Precision forming rollers made from suitable tool steel are designed to withstand repeated cold forming operations.
The roll forming machine can be customized according to the required split set diameter, material thickness, and product geometry.
The Split Set Dome Plate Press Machine is designed for manufacturing steel bearing plates used with compatible rock bolt systems.
A hydraulic pressing system applies forming force through customized tooling to produce the required plate geometry.
The machine supports repeated forming operations and can be equipped with suitable tooling according to the required plate dimensions.
Consistent plate geometry is important for proper installation and load transfer in the designed support system.
The Split Set Necking Machine is designed to shape the end section of a split set rock bolt according to the required product design.
It uses a hydraulic forming mechanism and customized tooling to process the prepared tubular component.
The machine provides a dedicated forming operation that can be incorporated into the overall rock bolt production arrangement.
The Split Set Ring Making Machine is used to manufacture metal rings required for compatible split set rock bolt assemblies.
Steel wire is processed into rings according to the configured tooling and required dimensions.
The equipment is designed for repeated ring production and can be customized according to the specified ring geometry and wire material.
The Split Set Ring Welding Machine is designed for joining prepared metal rings to compatible split set rock bolt components.
The equipment uses a TIG welding configuration and dedicated positioning arrangements to support repeatable welding operations.
The welding system can be customized according to the required bolt dimensions, ring arrangement, and product specifications.
Suitable weld quality inspection and production testing are recommended to verify that finished assemblies meet the relevant project requirements.
