Manhart ¿Cómo determinar el mal funcionamiento de la máquina dobladora?

Judging the malfunction of a bending machine usually involves multiple aspects of inspection and evaluation. The following is a systematic method for identifying and determining common faults in a downward bending machine:
###1、 Hydraulic system inspection
**Inspection content * *:
-Hydraulic oil level and quality: Observe whether the oil level in the hydraulic oil tank is within the normal range, and whether the oil quality is clean and free of impurities. Low oil level or oil contamination may cause the hydraulic system to malfunction.
-Hydraulic pump and cylinder: Check if the hydraulic pump and cylinder are running smoothly, without any abnormal noise or vibration. At the same time, observe whether the action of the oil cylinder is smooth and there is no jamming phenomenon.
-Hydraulic pipelines and joints: Check for leaks, damages, or looseness in the hydraulic pipelines to ensure that all joints are tightly connected and free of oil leakage.
-Pressure and Flow: Use a pressure gauge to check whether the pressure and flow of the hydraulic system meet the requirements. Abnormal pressure and flow may indicate a system malfunction.
###2、 Electrical system testing
**Inspection content * *:
-* * Power Supply and Cable * *: Confirm if the power supply is normal and if the cable connection is secure and undamaged. Use a multimeter to check if the power supply voltage is stable and avoid equipment malfunctions caused by power fluctuations.
-Motor and Driver: Check if the motor runs smoothly and if the driver indicator light is displaying properly. Pay attention to the temperature and vibration of the motor, any abnormal phenomena may indicate a motor or driver malfunction.
-Controller and PLC: Check if the display screens of the controller and PLC are displaying normally and if the input and output signals are accurate. Check for errors or anomalies in the control program through programming software.
-* * Sensors and Switches * *: Test the working status of various sensors (such as pressure sensors, position sensors) and switches (such as limit switches, safety switches) to ensure that they can accurately feedback the equipment status.
###3、 Mechanical component evaluation
**Inspection content * *:
-* * Transmission components * *: Check the wear and looseness of transmission components such as gears, chains, belts, etc. Pay attention to the operating sound of the transmission components and determine if there is any abnormal noise or vibration.
-Sliding block and worktable: Observe whether the movement of the sliding block and worktable is smooth and without any jamming. Check the wear of the slider guide rail and repair or replace it if necessary.
-Mold and clamping device: Check the wear of the mold and the tightness of the clamping device. Ensure good contact between the mold and the workpiece, and the clamping device can reliably fix the workpiece.
###4、 Operation and adjustment testing
**Test content * *:
-* * Manual operation * *: Check the response speed and action accuracy of each component by manually operating the equipment. Pay special attention to observing whether there are any abnormal movements or lagging phenomena of the device in manual mode.
-* * Automatic cycle * *: Run the equipment in automatic mode for a complete processing cycle and observe its stability and reliability. Pay attention to checking for any abnormal noises, vibrations, or oil leaks during the processing.
###5、 Parameter and Setting Review
**Review content * *:
-Control Parameters: Check whether the settings of various parameters in the control system are accurate and reasonable, including processing parameters such as pressure, speed, and angle. Compare the standard parameter values in the device manual or user manual to determine if the current settings are reasonable.
-* * Program and Code * *: Review the machining program and code to ensure they are correct and error free, ensuring they can correctly guide the equipment to complete the machining task. Pay special attention to checking for logical or grammatical errors in the program.
###6、 Safety and environmental factors
**Assessment Content * *:
-Safety devices: Check whether the safety devices of the equipment (such as emergency stop buttons, protective covers, etc.) are intact and effective. Ensure that the power can be quickly cut off in emergency situations and protect the safety of operators.
-Operating Environment: Evaluate whether the operating environment of the equipment meets the requirements, including the impact of factors such as temperature, humidity, and dust on the equipment. Ensure that the equipment operates in a dry, ventilated, and non corrosive gas environment.
Through the comprehensive inspection and evaluation of the above steps, it is possible to accurately determine the location of the fault in the lower bending machine. However, it should be noted that some faults may involve multiple factors, so comprehensive analysis and judgment are needed. For uncertain or complex faults, it is recommended to promptly contact professional maintenance personnel for handling.
