Care and Maintenance of Bending Centres

Bending centre operation process

Preparation before starting the equipment

Check whether the appearance of the equipment is intact, whether the components are fastened to ensure that there is no loosening, no damage.

Check whether the oil level of the hydraulic system is normal, whether the oil is clean, and replace it if necessary.

Check whether the wiring of the electrical system is firm, and whether the switches and buttons are flexible and reliable.

Check whether the bending mould is installed correctly and whether the mould gap is adjusted appropriately.

According to the processing requirements, select the appropriate bending programme and set the necessary parameters.

Equipment start-up and commissioning

According to the equipment start-up sequence, start the hydraulic system, electrical system, etc., to ensure that all parts of the equipment operate normally.

Carry out no-load operation of the equipment, check whether the movement of the components is smooth, no abnormal sound.

Carry out debugging of the bending mould to ensure that the mould gap is even and the bending angle is accurate.

Sheet loading and positioning

Place the plate to be bent on the feeding frame to ensure that the plate is flat and without warping.

Adjust the position of the positioning system according to the size of the plate and the bending requirements to ensure that the plate can enter the bending area smoothly.

Use the positioning device to accurately position the plate to ensure the accuracy of the bending position.

Bending process

Start the bending programme and the machine will automatically carry out the bending process of the plate.

The operator should pay close attention to the process to ensure that the plate in the bending process without sliding, no jamming phenomenon.

In case of emergency, the emergency stop button should be pressed immediately to ensure the safety of the equipment and personnel.

Finished product discharging and checking

After processing is completed, the equipment automatically sends the finished product out of the bending area.

The operator should unload the finished products in time and check whether the bending quality and dimensional accuracy of the finished products meet the requirements.

If there is any problem, it should be recorded and fed back in time for subsequent improvement and optimisation.

Equipment shutdown and cleaning

According to the sequence of equipment shutdown, shut down the hydraulic system, electrical system, etc., to ensure the safety of equipment shutdown.

Clean the metal chips, oil and other debris inside the equipment to keep the equipment clean internally.

Clean the outside of the equipment to ensure that the appearance of the equipment is clean and free of rust and corrosion.

Precautions for operation of bending centre

Safe Operation

The operator must be familiar with the safety operation regulations of the equipment, and strictly abide by the safety operation norms.

During the operation of the equipment, it is forbidden to touch the moving parts, so as to avoid accidents such as pinching and crushing.

In case of equipment failure or abnormal situation, the machine should be stopped immediately for checking and troubleshooting before continuing operation.

Standardised operation

The operator should operate in accordance with the requirements of the equipment operation manual, and should not change the parameters or procedures of the equipment at will.

In the process of sheet loading, positioning, bending, etc., it should be ensured that the operation is smooth and accurate, so as to avoid causing sheet damage or equipment damage.

After processing is completed, the finished products should be inspected and cleaned up in time to ensure that the quality of the finished products meets the requirements.

Maintenance awareness

Operators should establish maintenance awareness, regular maintenance of equipment to ensure that the equipment is in good condition.

In the operation process, they should pay attention to observe the running condition of the equipment, and if abnormalities are found, they should be handled and reported in time.

Keep the equipment around the clean and tidy, to avoid the accumulation of debris affect the normal operation of the equipment.

Maintenance of Bending Centre

Daily maintenance

Before starting the machine every day, check the fastening of each part of the machine to ensure that there is no looseness.

At the end of the day, clean up the metal chips, oil and other debris inside the equipment to keep the inside of the equipment clean.

Regularly check the oil level and oil quality of the hydraulic system, and replace or filter if necessary.

Regularly check the wiring and switches and other parts of the electrical system to ensure that the electrical system is safe and reliable.

Regular Maintenance

Carry out a comprehensive inspection of the equipment every month, including the wear and tear of the hydraulic system, electrical system, bending mould and other components.

Regularly grind and adjust the bending moulds according to the usage of the equipment to ensure even mould gap and accurate bending angle.

Perform comprehensive overhaul and maintenance of the equipment every year, including replacement of parts with serious wear and tear, and adjustment of equipment accuracy.

Maintenance Record

Establish a record sheet for equipment maintenance, recording in detail the time, content, personnel and other information of each maintenance.

Regularly analyse and summarize the maintenance records, so as to find out the problems and take improvement measures in time.

Maintenance records are kept and managed as part of the equipment files.

Common faults and troubleshooting of bending centre

Electrical system failure

Equipment can not start or start immediately after the shutdown: check whether the power supply is normal, whether the switch is damaged, whether the fuse is blown.

Sudden stop during the operation of the equipment: check whether the electrical wiring is poor contact, whether the sensor is out of order, whether the motor is overloaded.

Failure of bending mould

Inaccurate bending angle: check whether the gap between moulds is even, whether the moulds are firmly installed, whether the positioning device is accurate.

Stuck or sliding phenomenon in the bending process: check whether the plate is flat, whether the surface of the mould is smooth, whether the lubrication is sufficient.

Other common faults

Feed movement is not smooth or stagnant phenomenon: check whether the feed frame guide rail is clean, whether the lubrication is adequate, whether the transmission components are damaged.

Abnormal sound or vibration during the operation of the equipment: check whether the connection of each part is tight, whether the bearing is damaged, whether the lubrication is adequate, etc.

For the above faults, the operator should investigate and deal with them according to the actual situation. If they cannot solve the problem by themselves, they should contact the equipment supplier or professional maintenance personnel for maintenance.

Conclusion

As one of the important equipments for modern sheet metal processing, the standardisation of operation and maintenance of the bending centre is of great significance to ensure the normal operation of the equipment, prolong the service life and improve the production efficiency. Through the elaboration of this paper, we have a detailed understanding of the bending centre's operating procedures, precautions and maintenance points and methods. We hope that these contents can provide useful reference and help to users of the bending centre in the actual operation. At the same time, we also emphasize that operators in the actual operation should establish a sense of safety, standard operating practices, and regular maintenance and troubleshooting of the equipment to ensure the long-term stable operation of the bending centre and efficient production.
