Information
Defects and scraps of bundles and strands, the main problems are over-twist, inner or outer single wire break, lack of strands, single wire or strand surface scratches, single wire back strands, single wire peeling, scars, brittle breaks, Arching, inclusions, excessive or wrong wire diameter, wrong stranding direction, serpentine, large stranding pitch, unqualified length, loose strands, disordered wiring and crushing, scratches, bruises , The DC resistance of the conductive core of the wire and cable is unqualified, etc. Among them, over-twisting refers to the twisting phenomenon in the twisting process.
Reasons for over-twisting of cable bundles and twisted wire products: First, the number of turns of the twisted wire on the traction wheel is not enough, generally less than 4 turns, the friction is too small and slips, resulting in excessive twisting. The second is that the tension of the take-up wire is loose or the take-up reel does not rotate, and the rotor is still rotating, resulting in excessive twisting.
Excessive twisting of cable bundles and stranded wire products: If the outer single wire has been severely deformed and the damage is serious, there is no possibility to repair it, and only cut it. If the single wire is not severely damaged, you can separate the rotating part of the equipment from the traction part, rotate it in the opposite direction of the twisting, and retract the partially twisted part, then repair the core by hand, and wind the excess single wire to On the take-up reel, unite the equipment and the rotating body. After the loose over-pressure line mold, press the line forcefully and manually repair it with the mold, so that the production can be restarted.
