Automatic core punching machine plays a key role in the motor rotor production line, mainly responsible for accurately press-fitting key components such as bearings into the iron core.

一、Preparation stage

Material preparation: Ensure that the supply of iron core, bearings and other required parts is sufficient and the quality meets the production requirements.

Equipment inspection: carry out all inspections on the automatic core punching machine, including mechanical parts, electrical control system, sensors, etc., to ensure that the equipment is in good condition.

Parameter setting: according to the production requirements, set the parameters of automatic core punching machine, such as pressing force, pressing speed, holding time, etc..

二、automatic feeding and positioning

Automatic loading: use the automatic loading device to convey the iron core to the specified position and carry out preliminary positioning.

Accurate positioning: The core is accurately positioned by mechanical sensors to ensure the accuracy of the bearing press-fitting position.

三、press-fitting process

Fast-forward stage: the press head approaches the iron core at a faster speed to reduce the waste of non-working time.

Detection stage: When the press head approaches the bearing press fitting position, reduce the speed for detection to ensure the accurate contact between the press head and the rotor.

Press-fit phase: Once contact is detected, the press head presses the bearing at the set press-fit speed and pressure until it reaches the predetermined position.

Pressure holding phase: After reaching the predefined position, a certain pressure and time are maintained to ensure a tight fit between the bearing and the iron core.

Return stage: after the holding time, the press head automatically returns to the initial position, ready for the next press fitting.

四、Quality Inspection

Online inspection: In the process of press-fitting, real-time monitoring of press-fitting force and press-fitting depth and other parameters through sensors to ensure the quality of press-fitting.

Off-line inspection: off-line inspection of the finished rotor, including appearance inspection, size measurement, rotation test, etc., to ensure that the quality of the combination of bearings and cores meets the production requirements.

五、Unloading and subsequent processing

Automatic discharging: automatically conveying the finished rotor to the next process.

Data recording: Record the data of each press-fitting, including press-fitting force, press-fitting depth, holding time, etc., so as to trace and analyze the quality.

六、Precautions

Standardized operation: In the process of operation, strictly abide by the operating procedures.

Maintenance: regular maintenance of automatic core punching machine, including cleaning, lubrication, inspection, etc., in order to extend the service life of the equipment and improve production efficiency.
