The wire transport mechanism in the middle wire is composed of the guide
wheel, the wire storage barrel, and the wire rack. Among them, when the accuracy
of the wire feed mechanism slowly decreases, it will cause axial movement and
radial runout in the yarn storage barrel. Of course, the accuracy here mainly
refers to the accuracy of the drive bearing.
The CNC machine tool control system supplier pointed out that if the radial runout between the middle wire storage drums will cause the tension between the electrode wires inside to slowly decrease, which will cause wire loosening. It will cause the molybdenum wire to be taken out of the guide wheel groove in the wire cutting machine, and even be pulled off. Moreover, the axial movement between the yarn storage drums will also lead to the inability to distribute the yarn evenly, and sometimes the situation of overlapping filaments and the like may also occur.

Bearings, shafts and other parts in the wire storage barrel often have some gaps due to wear, and it is also easy to cause the middle wire to shake and cause wire breakage, so be sure to wear the bearing, shaft, etc. in the machine in time Wait for parts to be replaced. When the wire storage barrel is reversed, if the high frequency power supply inside is not cut off, it will cause the molybdenum wire in the middle wire to burn out the molybdenum wire because the temperature is too high in a very short time Situation, so be sure to check whether the travel switch on the back of the yarn storage barrel is normal, whether there is any malfunction, etc.
If you want to keep the rotation between the guide wheel and the wire storage barrel very flexible, you must pay attention to whether the molybdenum wire inside shakes when they move back and forth. If the molybdenum wire shakes, you must analyze the cause of the situation. what. Moreover, the limit stop at the rear end of the wire storage barrel should be adjusted properly, so that the wire storage barrel can be prevented from breaking due to the punch out of the machine's limit stroke.
For the normal fast-moving molybdenum wire in the wire stopper to come into contact with the stopper, it is easy to cause grooves and lead to the wire being pulled off, so it must also be replaced in time, so the wire walking machine in use It is necessary to check the accuracy of the wire transport mechanism.
