The single wire is broken when it is twisted, and the single wire is broken when the strand is missing
Causes: ●The wire core is broken due to excessive pay-off tension. ●When the single wire is drawn, the wire is loose, the wire is not well arranged, and the wire is pressed across the wire, causing the wire core to break. ●There are cracks in the material of the single wire itself, and the mechanical properties are not good and brittle. ●The installation position of the pay-off reel is improper, and the shaft is shaken, resulting in disconnection. ●The single line jumps out of the pulley groove and is mechanically stuck.
Remedy: ● Adjust the pay-off tension to make it appropriate. ● Pay attention to the selection of the incoming wire, and find that there is a loose phenomenon when pulling the wire, and it must be rewound before it can be used on the machine. ● Pay attention to the operation method, carefully check the position of the pay-off reel, so that the paid-out line does not swing or jump, and check the place where the single line passes, whether there is any phenomenon of jumping out of the guide wheel groove. ● Check the surface quality of the wire core to see if there are cracks, slag inclusions, scars and other defects. If the broken wire occurs in the inner layer, and the broken end has gone too long, it cannot be repaired. Only by cutting off the missing strand core, if the broken wire occurs in the outer layer, the wire should be repaired before starting the machine.
