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. Hindi gumagana ang hydraulic system
*Suriin ang mga hydraulic component: Suriin kung ang mga hydraulic component gaya ng mga oil pump, oil cylinder, at relief valve ay nasira o abnormal.
*Linisin ang circuit ng langis: Suriin kung naka-block ang circuit ng langis, linisin ang circuit ng langis kung kinakailangan, at palitan ang hydraulic oil.
*Suriin ang antas ng langis: Suriin ang kalidad at antas ng hydraulic oil upang matiyak na ito ay malinis at sapat.
#### 2. Malfunction ng electrical system
*Suriin ang mga de-koryenteng bahagi: Suriin kung ang motor, mga de-koryenteng bahagi, sensor, atbp. ay nasira o hindi gumagana.
*Suriin ang circuit: Gumamit ng multimeter o iba pang tool para tingnan kung maganda ang circuit connection, kung mayroong short circuit o open circuit.
*Suriin ang power supply: Suriin kung ang boltahe ng power supply ay stable at nakakatugon sa mga kinakailangan sa kagamitan.
#### 3. Hindi gumagana ang mekanikal na sistema
** * Suriin ang mga mekanikal na bahagi * *: Suriin kung ang slider guide rail, amag, mga bahagi ng transmission, atbp. ay pagod o nasira.
** * Suriin ang mga fastener * *: Suriin kung ang mga koneksyon sa pagitan ng bawat bahagi ay mahigpit at kung mayroong anumang pagkaluwag.
*Pagpapadulas ng pagpapadulas: Suriin kung ang sistema ng pagpapadulas ay gumagana nang maayos upang matiyak na ang mga mekanikal na bahagi ay sapat na lubricated.
#### 4. Mga isyu sa amag at materyal
*Suriin ang amag: Suriin kung ang amag ay pagod, deform, o nasira upang matiyak na tumutugma ito sa materyal.
** * Suriin ang mga materyales * *: Suriin kung ang materyal, kapal, tigas, atbp. ng mga materyales ay nakakatugon sa mga kinakailangan sa pagproseso ng kagamitan.
#### 5. Iba pang mga isyu
*Suriin ang base at fixation: Suriin kung ang base ng device ay stable at kung ang lahat ng mga bahagi ay ligtas na naayos.
*Suriin ang control system: Para sa mga kagamitang may mataas na antas ng automation, kinakailangan ding suriin kung normal na gumagana ang control system.
###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.
