Case:
A manufacturing company uses a motor motor rotor automatic core punching machine for rotor production. During the production process, abnormal noise suddenly appeared on the machine, and the accuracy of core punching decreased, resulting in lower production efficiency and affecting the delivery date.
Failure phenomenon
Abnormal noise: the equipment made a large friction sound during operation, and the sound was irregular.
Reduced accuracy of core punching: The size of the rotor produced was out of specification, which prevented the subsequent processes from proceeding normally.
Failure Analysis
After preliminary inspection, technicians found:
The noise originates from the spindle part of the equipment, probably due to bearing wear or insufficient lubrication.
The decrease in core punching accuracy may be due to severe wear of the mold, resulting in inaccurate positioning during core punching.
Solution
Tackle the abnormal noise:
Step 1: Turn off the equipment and conduct a thorough inspection, especially the spindle and bearing section.
Step 2: It was found that the spindle bearings were visibly worn and it was decided to replace them with new ones.
Step 3: While replacing the bearings, clean the spindle and its surrounding lubricant, add appropriate amount of high quality lubricant to ensure good lubrication.
Step 4: Restart the equipment and observe the noise situation to confirm that the noise problem has been solved.
Restore the accuracy of punching core:
Step 1: Check the mold and find that the punch of the mold is badly worn, resulting in a loss of core punching accuracy.
Step 2: Replace the punch with a new one and calibrate the mold to make sure it meets the design requirements.
Step 3: Conduct a trial production and check the rotor dimensions to make sure they are within specification.
After implementing the above solutions, the operating condition of the Motor Motor Rotor Automatic Core Punching Machine improved significantly:
The noise level of the machine was reduced to the normal range and the operation was smooth.
The size of the rotors produced meets the standard, the accuracy of the core punching is restored, and the production efficiency is improved.
Through the fault analysis and treatment of motor motor rotor automatic core punching machine, the enterprise not only solved the current problem, but also enhanced the awareness of equipment maintenance. It is recommended to carry out comprehensive inspection and maintenance of the equipment on a regular basis to prevent the recurrence of similar failures and ensure smooth production.
