Manhart How to quickly troubleshoot and repair when a bending machine malfunctions?

When the front bending machine malfunctions, in order to ensure quick troubleshooting and repair, the following steps can be taken:
###1、 Preliminary diagnosis of malfunction
1. * * Observe the fault phenomenon * *:
-Pay attention to the specific performance of the equipment when a malfunction occurs, such as whether there is abnormal noise, vibration, shutdown, etc.
-Observing error messages or indicator light status on the display screen can usually provide direct fault clues.
2. * * Ask the operator * *:
-Understand the operational situation before the fault occurred, such as whether parameter adjustments were made, mold replacements, etc.
-Ask the operator if they have noticed any abnormal situations or abnormal sounds.
###2、 Classification and investigation
According to the fault symptoms, the faults of the downward bending machine can be roughly divided into several categories: hydraulic system faults, electrical system faults, mechanical system faults, angle adjustment problems, mold and material problems, abnormal noise and vibration, base and fixing problems, etc. The following are troubleshooting and repair methods for various types of faults:
#### 1. Hydraulic system malfunction
-Check hydraulic components: Check whether the oil pump, oil cylinder, relief valve and other components are damaged or abnormal.
-* * Cleaning oil circuit * *: Check if the oil circuit is blocked. If necessary, clean the oil circuit and replace the hydraulic oil.
-Check the oil: Check if the oil is contaminated or deteriorated, and replace it with clean oil if necessary.
#### 2. Electrical system malfunction
-Check electrical components: Check whether the motor, electrical components, sensors, etc. are damaged or malfunctioning.
-Check the circuit: Check whether the circuit connection is good, whether there is a short circuit or open circuit.
-* * Test power supply * *: Check whether the power supply voltage is stable, whether there is fluctuation or insufficient.
#### 3. Mechanical system malfunction
-* * Check mechanical components * *: Check whether the slider guide rail, mold, transmission components, etc. are worn or damaged.
-* * Check fasteners * *: Check whether the connections between each component are tight and whether there is any looseness.
-Lubrication maintenance: Check if the lubrication system is working properly to ensure that mechanical components are adequately lubricated.
#### 4. Angle adjustment issue
-* * Calibrate angle sensor * *: Use professional tools to calibrate the angle sensor and ensure its accuracy.
-Adjust the angle adjustment mechanism: Check and adjust the transmission ratio and limit device of the angle adjustment mechanism.
#### 5. Mold and material issues
-Check the mold: Check if the mold is worn or damaged, and replace it promptly if necessary.
-Check materials: Ensure that the material and thickness of the processed materials meet the equipment requirements.
#### 6. Abnormal noise and vibration
-Check fasteners: Tighten loose fasteners and eliminate vibration sources.
-Check the transmission components: Check whether the transmission components are worn or damaged, and replace them if necessary.
#### 7. Base and fixing issues
-Check the base: Check if the base is stable, loose or deformed.
-Check the fixing device: Check whether the fixing device of the equipment is firm and reliable.
###3、 Professional maintenance
-* * Contact professional technicians * *: For complex or difficult to solve faults, timely contact professional technicians for maintenance.
-* * Provide fault information * *: Provide detailed descriptions of the fault phenomenon and preliminary investigation results to the maintenance personnel, so that they can quickly locate the problem.
-* * Cooperate with maintenance work * *: Actively cooperate with maintenance personnel during the maintenance process, providing necessary assistance and support.
###4、 Record and Summary
-* * Record fault information * *: Record detailed information such as fault symptoms, troubleshooting process, and repair methods for future reference and analysis.
-* * Summarize lessons learned * *: Summarize the causes and lessons of this malfunction, propose improvement measures, and prevent similar malfunctions from happening again.
By following the above steps, it is possible to quickly troubleshoot and repair faults in the downward bending machine, ensuring that the equipment can resume normal operation. At the same time, attention should also be paid to strengthening the maintenance and upkeep of equipment in daily use to reduce the probability of malfunctions.
