Operation Tutorial for the Fully - automatic CNC Bending Hoop Machine for Applying Hoop Reinforcement

1. Preparation Before Operation

1.1 Machine Inspection

• Check if all parts of the fully - automatic CNC steel bar bending hoop machine are firmly connected. Ensure that there are no loose bolts or components that could pose a safety hazard during operation.

• Examine the lubrication condition of each moving part. Adequate lubrication can reduce wear and tear and ensure smooth operation. Add lubricating oil as required.

• Inspect the electrical system. Make sure all electrical connections are secure, and there are no signs of short - circuits or exposed wires. Check if the power supply voltage matches the machine's requirements.

1.2 Material Preparation

• Select the appropriate steel bars according to the design requirements of the hoop reinforcement. Ensure that the steel bars are straight, free from cracks, and have the correct diameter.

• Calculate the length and quantity of steel bars needed for the hoop reinforcement based on the construction drawings. Cut the steel bars to the approximate length if necessary.

2. Machine Setup

2.1 Loading the Steel Bars

• Place the steel bars on the feeding platform of the machine. For some models, there may be a guide rail to help align the steel bars properly. Make sure the steel bars are placed straight and in line with the feeding direction.

• Some machines may have an automatic feeding device. If so, adjust the feeding speed and other parameters according to the diameter and properties of the steel bars.

2.2 Program Input

• Turn on the CNC control system of the machine. Navigate to the program input interface.

• Enter the parameters for the hoop reinforcement, such as the diameter of the steel bar, the size of the hoop (length of each side, radius of the bend), the number of hoops to be produced, and the bending angle. Most machines have a pre - set library of common hoop shapes, which can be selected and adjusted as needed.

• Review the input parameters carefully to ensure their accuracy. Incorrect parameters may lead to the production of non - conforming hoop reinforcement.

3. Operation Process

3.1 Start the Machine

• After confirming that the setup is correct, press the start button to initiate the operation. The machine will first start the straightening process if the steel bars need straightening. The straightening rollers will gradually adjust the straightness of the steel bars as they pass through.

• Once the steel bars are straightened, they will be fed into the bending mechanism. The bending head will rotate according to the set parameters to form the required hoop shape.

3.2 Monitoring the Process

• During the operation, closely monitor the machine's operation status. Observe whether the steel bars are being fed smoothly, if the bending angles are accurate, and if there are any abnormal noises or vibrations.

• Check the produced hoop reinforcement at regular intervals. Measure the size of the hoops to ensure they meet the design requirements. If any deviations are found, stop the machine immediately and adjust the relevant parameters.

4. Post - operation Procedures

4.1 Machine Shutdown

• After completing the production of the required number of hoop reinforcement, press the stop button to halt the machine. Turn off the power supply to ensure safety.

• If there are any remaining steel bars on the feeding platform, remove them carefully.

4.2 Machine Cleaning and Maintenance

• Clean the machine to remove any steel debris, dust, or oil stains. Use a clean cloth or brush to wipe the surfaces of the machine, especially the straightening rollers, bending heads, and feeding channels.

• Check the wear condition of key components such as the bending dies and straightening rollers. Replace any worn - out parts in a timely manner to ensure the next operation's quality.

• Lubricate the moving parts again to prevent rust and ensure smooth operation for the next use.
