Manhart How to determine the cause of the malfunction of the bending machine?

Determining the cause of the malfunction of the bending machine is a systematic and meticulous process that involves multiple aspects of inspection and analysis. Here are some commonly used judgment methods and steps:
###1、 Observation of Fault Phenomena
Firstly, it is necessary to carefully observe the specific performance of the bending machine when a fault occurs, such as whether there are abnormal noises, vibrations, shutdowns, inaccurate processing angles, material wrinkles, and other issues. These phenomena often directly reflect the type and location of equipment failure.
###2、 Ask the operator
Understand the operational situation before the fault occurred, including whether there were parameter adjustments, mold replacement, material changes, and other operations. At the same time, asking the operator if they noticed any abnormal situations or sounds is very helpful for quickly locating the cause of the fault.
###3、 Classification diagnosis
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, mold and material problems, and other problems, and diagnosed one by one.
#### 1. Hydraulic system malfunction
*Check hydraulic components: Check whether hydraulic components such as oil pumps, oil cylinders, and relief valves are damaged or abnormal.
*Clean the oil circuit: Check if the oil circuit is blocked, clean the oil circuit if necessary, and replace the hydraulic oil.
*Check the oil level: Check the quality and level of the hydraulic oil to ensure that it is clean and sufficient.
#### 2. Electrical system malfunction
*Check electrical components: Check whether the motor, electrical components, sensors, etc. are damaged or malfunctioning.
*Check the circuit: Use a multimeter or other tools to check whether the circuit connection is good, whether there is a short circuit or open circuit.
*Test power supply: Check if the power supply voltage is stable and meets the equipment requirements.
#### 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. Mold and material issues
*Check the mold: Check if the mold is worn, deformed, or damaged to ensure that it matches the material.
** * Check materials * *: Check whether the material, thickness, hardness, etc. of the materials meet the processing requirements of the equipment.
#### 5. Other issues
*Check the base and fixation: Check if the device base is stable and if all components are securely fixed.
*Check the control system: For equipment with a high degree of automation, it is also necessary to check whether the control system is operating normally.
###4、 Use professional tools and testing methods
During the diagnostic process, some professional tools and equipment can be used to assist in testing, such as multimeters, oscilloscopes, hydraulic oil detectors, etc. These tools can help us more accurately determine the cause and location of faults.
###5、 Comprehensive analysis and judgment
Based on the fault symptoms, information provided by operators, classification diagnosis results, and detection data from professional tools, conduct comprehensive analysis and judgment. After determining the specific cause of the malfunction, develop corresponding repair plans and implement repair work.
###6、 Precautions
*During the diagnostic process, safety should always be taken into account to ensure the safety of equipment and operators.
*For complex or difficult to diagnose faults, professional technicians or after-sales personnel from equipment manufacturers can be hired to assist in diagnosis.
*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.
Through the above steps and methods, we can effectively determine the cause of the malfunction of the bending machine and take corresponding measures for repair.
