**Common troubleshooting and treatment measures for hydraulic servo CNC bending machines**
I. Introduction
As key equipment in the sheet metal processing industry, the stable operation of hydraulic servo CNC bending machines is crucial to ensuring production efficiency and product quality. However, due to long-term operation or improper operation of the equipment, some faults often occur. This article aims to introduce the troubleshooting, treatment and preventive measures of common faults of hydraulic servo CNC bending machines to help users better maintain and use the equipment.
II. Fault diagnosis and detection methods
1. Observation method: Preliminary judgment of the fault type and location by observing the equipment operating status, indicator lights, alarm information, etc.
2. Inquiry method: Asking the operator about the use of the equipment, changes before and after the fault occurs, etc., will help narrow the scope of troubleshooting.
3. Detection method: Use professional detection tools to detect the equipment, such as multimeters, oscilloscopes, etc., to obtain more accurate fault information.
3. Common fault phenomena and cause analysis
1. Fault phenomenon: The equipment cannot start
Cause analysis: Power failure, controller failure, fuse blown, etc.
2. Fault phenomenon: Inaccurate bending angle
Cause analysis: Mold wear, improper parameter setting, sensor failure, etc.
3. Fault phenomenon: Insufficient pressure in the hydraulic system
Cause analysis: Oil pump damage, hydraulic pipeline leakage, oil contamination, etc.
4. Troubleshooting steps and techniques
1. Determine the fault phenomenon and scope, and select the appropriate troubleshooting method according to the fault phenomenon.
2. According to the fault phenomenon and cause analysis, gradually troubleshoot possible causes of the fault.
3. Use professional tools to test the equipment and obtain accurate fault information.
4. Determine the cause of the fault based on the test results and take corresponding treatment measures.
5. Treatment measures and maintenance methods for different faults
1. The equipment cannot start: Check whether the power supply, fuse, etc. are normal. If there is a problem, replace it in time; check whether the controller is damaged. If damaged, it needs to be replaced or repaired.
2. Inaccurate bending angle: Check whether the mold is worn or improperly installed. If there is a problem, replace or adjust it in time; Check whether the parameter settings are correct. If not, reset it.
3. Insufficient pressure in the hydraulic system: Check whether the oil pump is damaged or severely worn. If there is a problem, replace it in time; Check whether the hydraulic pipeline is leaking. If there is a leak, repair it in time; Regularly replace the hydraulic oil and filter to ensure that the oil is clean and pollution-free.
VI. Equipment maintenance and preventive maintenance plan
1. Clean and lubricate the equipment regularly to keep the equipment clean and tidy to reduce the occurrence of failures.
2. Regularly check whether the fasteners, transmission parts, etc. of the equipment are loose or worn, and tighten or replace them in time.
3. Regularly maintain the hydraulic system of the equipment, including replacing hydraulic oil, cleaning filters, etc., to ensure the normal operation of the hydraulic system.
4. Develop a preventive maintenance plan and perform regular maintenance according to the plan to improve the service life and stability of the equipment.
VII. Train operators to improve equipment use and maintenance capabilities
1. Strengthen the training of operators to familiarize them with the operating procedures and safety precautions of the equipment.
2. Improve the equipment maintenance awareness of operators so that they can find and deal with equipment failures in time.
3. Regularly organize maintenance personnel to participate in professional training to improve their fault diagnosis and maintenance capabilities.
VIII. Regularly check and update equipment parts to ensure their normal operation
1. Regularly check the key parts of the equipment, such as oil pumps, motors, sensors, etc., to ensure that they are in good working condition.
2. If necessary, replace severely worn or aged parts in time to ensure the normal operation of the equipment.
3. Establish equipment parts archives to record the replacement and service life of parts to provide a reference for equipment maintenance.
IX. Monitor and optimize equipment operation data to improve production efficiency and safety
1. Real-time monitoring of the equipment’s operating status and operating data, such as temperature, pressure, speed, etc., to ensure that they are within the normal range.
2. Through the analysis of equipment operation data, find out the factors that affect production efficiency and safety, and optimize and improve them.
3. Regularly optimize and adjust the equipment to improve the processing accuracy and production efficiency of the equipment.
