Fully Automatic Anchor Rod Roll Forming Machine with PLC Control

Anchor rodsare the core supporting components that maintain the safety of underground structures in mining, tunnel excavation, and geotechnical anchoring engineering. It is deeply buried in the rock layers and withstands enormous tests of ground pressure, vibration, and displacement. The Fully Automatic Anchor Rod Roll Forming Machine with PLC Control is a specialized equipment designed for efficient, precise, and mass production of this critical safety component, upgrading traditional manufacturing to intelligent continuous production.

What is a Fully Automatic Anchor Rod Roll Forming Machine ?

The fully automatic steel anchor rod roll forming machine is an automated production line that uses cold bending roll forming technology to continuously process high-strength steel strips into pipe seam anchor rods (also known as split type anchor rods, friction anchor rods). The equipment is based on cold bending technology, which applies multiple progressive deformations to metal strip at room temperature, and can complete the complete processing from steel strip to finished anchor rod without heating.

The pipe seam anchor produced by this equipment is a supporting component that works based on the principle of friction: high-strength steel pipes with longitudinal cutting seams, which expand radially after being inserted into slightly smaller diameter boreholes, forming continuous frictional resistance along the entire length of the anchor, thereby firmly locking the rock layers together. Anchor rods are widely used in coal mine roadway support, mine tunnel support, water conservancy and hydropower engineering cavern support, slope reinforcement, and foundation pit support.

The equipment mainly consists of unwinding device, leveling device, roll forming host, sizing straightening device, flying saw/hydraulic shearing system, PLC electronic control system, and discharge platform.

Core advantage: Redefine anchor rod production：

1. Fully automatic PLC intelligent control, one click production
The equipment is equipped with advanced PLC control system and human-machine interface (HMI), achieving full process automation from unwinding and feeding to finished product output. The operator only needs to set the parameters such as anchor rod length and quantity on the touch screen, and the equipment can automatically complete all processes such as unwinding, leveling, multi pass roll forming, sizing straightening, and fixed length cutting. The core components of the control system are sourced from internationally renowned brands such as Mitsubishi, ensuring stable and reliable operation of the equipment. Some high-end models are also equipped with real-time monitoring systems that can track the molding pressure and material alignment, providing full technical support for product quality.

2. High precision molding, stable and reliable quality
The support performance of anchor rods directly depends on their geometric accuracy – deviations in outer diameter or uneven longitudinal cutting can lead to catastrophic loss of frictional resistance. The fully automatic anchor rod roll forming machine adopts multiple precision forming rollers to gradually roll high-strength steel strips into circular tube structures with longitudinal cutting seams. The rollers are made of high hardness mold steel such as GB-Cr12, which has undergone precision machining and heat treatment. The equipment precisely controls the outer diameter and roundness of the anchor rod through a multi-stage sizing and straightening device, ensuring that the cross-sectional dimensions of each anchor rod are consistent and the straightness meets the standard, thereby ensuring that each anchor rod can work reliably under extreme load conditions.

3. High speed production, astonishing production capacity
The fully automatic anchor rod roll forming machine has extremely high production efficiency. Depending on the configuration, the molding speed can reach 0-20 meters per minute. A production line only requires 1-2 people to be on duty, significantly reducing labor input. Taking the production of pipe seam anchor rods with a diameter of 30-50mm and a length of 800-6000mm as an example, an 8-hour shift can produce about 2500 finished anchor rods, far exceeding traditional processing methods.

4. Cold bending forming, energy-saving and environmentally friendly
The equipment adopts cold bending forming technology, and all deformations are completed at room temperature. Compared with traditional hot rolling or cutting processing, there is no need for heating or cutting waste, which not only significantly reduces energy consumption, but also improves the density and strength of the material. The radial compressive stress generated by cold bending can significantly improve the fatigue strength and torsional strength of the workpiece, making it an efficient, energy-saving, and low consumption ideal process.

5. Modular design, one machine with multiple functions
The equipment adopts modular design, and by replacing roller molds of different specifications and adjusting parameters, it can produce pipe seam anchor rods of different diameters (Φ 70mm), wall thicknesses (2.4-3.2mm), and steel grades. A complete anchor rod production line can also integrate supporting equipment such as necking machines, ring making machines, ring welding machines, pallet presses, etc., to achieve one-stop production of the entire process from steel strips to finished anchor rods.
