Manhart Làm thế nào để chẩn đoán và sửa chữa nhanh chóng các lỗi khuôn của máy uốn nhằm giảm ảnh hưởng đến dây chuyền sản xuất?

After the failure of the bending machine mold, in order to quickly diagnose and repair it and reduce the impact on the production line, the following steps can be taken:
###1、 Quick diagnosis
1. * * Fault phenomenon record * *:
-Record in detail the phenomena that occurred during the malfunction, such as mold failure to close, deviation in workpiece processing accuracy, mold damage, etc.
-Observe and record the operating conditions, processing parameters, etc. before and after the occurrence of the fault for subsequent analysis.
2. * * Preliminary examination * *:
-Appearance inspection: Check the surface of the mold for signs of cracks, wear, deformation, etc.
-* * Function check * *: Try running the bending machine manually or at low speed, observe the movement trajectory and fit of the mold.
3. * * In depth analysis * *:
-Electrical system inspection: For the bending machine controlled by electro-hydraulic servo, check whether the electrical system is normal, such as the motor, driver, sensor, etc.
-Hydraulic system inspection: Check whether the pressure, flow rate, oil temperature and other parameters of the hydraulic system are normal, whether the oil is clean, and whether the hydraulic components are damaged.
-Mechanical structure inspection: Check whether the guiding mechanism, fastening components, transmission mechanism, etc. of the mold are intact, whether there is looseness, wear or fracture.
4. * * Professional tool assistance * *:
-Use measuring tools such as vernier calipers and micrometers to check the accuracy and fit clearance of the mold.
-With the help of professional equipment such as vibration analyzers and infrared thermometers, more in-depth diagnosis of mechanical components and hydraulic systems can be carried out.
###2、 Quick repair
1. * * Spare parts preparation * *:
-Based on the diagnosis results, prepare the necessary spare parts and maintenance tools in advance, such as replacement mold components, fasteners, seals, etc.
2. * * Safe operation * *:
-Before carrying out repair operations, ensure that the bending machine has been powered off or stopped, and take necessary safety measures such as wearing protective equipment, using safety fixtures, etc.
3. * * Targeted repair * *:
-Replace damaged parts: For mold components that are severely worn or damaged, replace them in a timely manner.
-Adjust the fit clearance: Adjust the guiding mechanism, transmission mechanism, etc. of the mold to ensure a reasonable fit clearance.
-Tighten loose parts: Check and tighten all loose fasteners to ensure the stability of the mold structure.
-Cleaning and lubrication: Clean and lubricate molds and mechanical components to reduce friction and wear.
4. * * Trial operation verification * *:
-After the repair is completed, conduct a trial run to verify whether the motion trajectory and processing accuracy of the mold meet the requirements.
-If any problems are found, adjust and optimize them in a timely manner to ensure that the mold returns to normal working condition.
5. * * Record and Summary * *:
-Record in detail the fault diagnosis, repair process, and results, and summarize the experience and lessons learned.
-Summarize and organize the problems discovered during the maintenance process, propose improvement measures and suggestions to enhance the reliability and service life of the mold.
Through the above steps, rapid diagnosis and repair of bending machine mold faults can be achieved, reducing the impact on the production line. At the same time, enterprises should strengthen the daily maintenance and upkeep of molds, improve their reliability and stability, and reduce the incidence of failures.
