Repair machinery, repair or replace molds:

After operating the movable part of the spinning machine to a convenient location for maintenance, the machine must be stopped and power cut off before maintenance or other work can be carried out.

The main shaft of the CNC spinning machine may have the following faults during the directional quasi-stop:

Spindle disorientation

When the spindle rotates, its actual speed display value is provided by the pulse sensor, the phase of the two rectangular pulses reflects the rotation of the spindle, and the number of pulses reflects the actual speed of the spindle. When the M19 direction stops, if the spindle has been rotating slowly, it means that the second and the first step have been performed, the spindle has entered the cutting speed, but not the first and second step, and the first and second step are the reference points of the reference pulse of the pulse sensor. Therefore, it can be judged that the non-directional fault of the main shaft of the CNC spinning machine is mostly caused by the pulse sensor, and then it should be detected to confirm the fault. The connectors and cables should be checked first for damage or poor contact, and if necessary, for good fastening and fastening of the fixing bolts of the sensor and the screws on the connector. If no problem is found, the sensor should be repaired or replaced.

The spindle is in an incorrect position

This fault usually occurs after the reinstallation and replacement of the sensor, at which time the sensor shaft cannot be located in the same position as before. The orientation position of the spindle can be adjusted by setting data. Changing the positioning tolerance of the spindle of the CNC spinning machine can correct the stop position of the spindle. When the offset Angle is corrected, the negative Angle value cannot be entered after the positioning tolerance of the spindle. The adjustment process often needs to be repeated many times, as long as the positioning tolerance of the spindle 10-11 degrees can be adjusted smoothly to replace the mold.

The cost of a spinning machine is not cheap, operators in the operation of the spinning machine in addition to standard operation, the maintenance of spinning machine should also pay special attention. The operation of the spinning machine should be achieved listening, observing and adjusting, and maintenance should also be achieved in these three aspects. Extending the service life of the spinning machine is also a key ability evaluation project for operators and workshop managers.

Listening, observing and adjusting in the operation of spinning machine

I. listening, viewing and tuning before operation:

Check whether the fasteners are loose; The typical parts are screw plate bolts and wheel bolts. Check the proximity switch and block are firm and reliable. No-load operation for 5-10 minutes, check whether the machine noise, vibration, cooling and lubrication are normal, whether the pressure has fluctuation, and whether the pressure indication is normal.

Ii. Cleaning after spinning:

1. Clean the site, clean the ground around the machine and wipe the appearance of the main engine.

Requirement: the floor around the machine is clean and the mold is put in order. Machine appearance cleaning to see paint see color iron see light. The exposed sliding surface is oiled to prevent rust.

2. Wipe the external surface of the hydraulic station to remove oil stains on all components and external pipe fittings. Keep the appearance clean.

3. Wipe the external surface of each cabinet to keep the appearance clean.

4. Carefully perform shift handover: shift staff must explain the operation of major parts of the CNC spinning machine in the production process to the shift staff according to the operation record of the machine. After confirming the normal operation of each department, the shift staff can sign on the shift transfer record.
