Manhart如何判断折弯机的故障？

Determining the malfunction of the bending machine is a systematic and meticulous process that requires comprehensive consideration of multiple aspects. Here are some common methods and steps to determine the fault of the bending machine:
###1、 Observation of Fault Phenomena
Firstly, it is necessary to carefully observe the specific performance of the bending machine when a malfunction occurs. The fault symptoms usually include the following:
** * Mechanical failure phenomena * *: such as the slider not moving, the worktable not being stable, and the mold being damaged, these phenomena may be related to wear, loose connections, or poor lubrication of mechanical components.
*Hydraulic system malfunction symptoms: such as oil pump failure, oil cylinder failure, unstable oil pressure, etc., these phenomena may be caused by hydraulic component damage, oil circuit blockage, or oil contamination.
** * Electrical system malfunction symptoms * *: such as motor malfunction, damaged electrical components, sensor failure, etc., these phenomena may be caused by aging electrical components, poor circuit contact, or unstable power supply.
###2、 Troubleshooting steps
1. * * Shutdown inspection**
-Stop all moving parts of the bending machine and ensure that there is no power source driving to avoid accidental start-up or mechanical injury during the inspection process.
2. Power off operation**
-Cut off all power supply to the lower bending machine, including the main power switch and control power, to prevent electric shock injury and accidental equipment start-up.
3. * * Preliminary examination**
-Inspect the appearance of the equipment for any obvious damage, oil leakage, or burnt electrical components.
4. * * System classification investigation**
-Mechanical system: Check the wear of mechanical components, whether connections are loose, and whether lubrication is good. Focus on inspecting the slider guide rail, mold, transmission components, etc.
-Hydraulic system: Check the integrity of hydraulic components, whether the oil circuit is blocked, and the quality and level of the oil. Focus on inspecting hydraulic components such as oil pumps, oil cylinders, and relief valves.
-Electrical system: Check whether the electrical components are working properly, whether the circuit connections are good, and whether the sensors are malfunctioning. Focus on inspecting motors, electrical components, sensors, and control circuits.
5. * * Application of professional testing tools**
-Use professional tools such as multimeters, oscilloscopes, and hydraulic oil detectors to test equipment and obtain more accurate fault information.
6. * * Gradual investigation method**
-If the fault phenomenon is not obvious or it is difficult to directly determine the cause of the fault, a step-by-step troubleshooting method can be used. That is, to investigate possible fault points one by one and determine the cause of the fault through trial operation or testing.
###3、 Comprehensive analysis and judgment
Based on the fault symptoms, troubleshooting steps, and the results of professional testing tools, conduct comprehensive analysis and judgment. After determining the specific cause of the malfunction, develop corresponding repair plans and implement repair work.
###4、 Precautions
*Throughout the entire fault diagnosis process, it is important to maintain safety awareness and adhere to safety operating procedures.
*For uncertain fault points or complex fault phenomena, it is recommended to seek the assistance of professional technicians or after-sales personnel from equipment manufacturers to make judgments.
*After the repair is completed, equipment testing should be conducted to verify whether the fault has been resolved and ensure that the equipment can operate normally.
By following the above steps and methods, the cause of the malfunction of the bending machine can be accurately determined, and corresponding measures can be taken for repair.
