Solutions of Single Wire Grooving or Surface Defect in Stranded Wire
2021-04-01
In the stranding machine, there may be defects such as single wire grooving or surface pockmarking, scar, triangular crack, slag inclusion, etc. In this case, we don't have to worry too much. Find out the reason and then solve it.
Causes of single wire grooving or surface defects in stranded wire:
Pockmarks, scars, triangular cracks, slag inclusions and other defects on the surface of single track are mainly caused by materials. Of course, the wire core surface fragmentation phenomenon, also does not rule out the wire die pass unreasonable. In this case, we need to analyze the specific situation. However, the continuous grooving on the surface of the core is generally caused by the pulling of wires. The deterioration of the lubrication conditions of the wires and the sticking of aluminum on the surface may cause the discontinuous grooving, which may be caused by the sticking of foreign matters on the stranding die.
Solutions:
When the aluminum wire is grooved, it is necessary to check whether the lubrication effect of the stay wire can meet the requirements of the stay wire. It is necessary to replace the lubricating oil, replace the stay wire mold, or remove the impurities stuck on the wire mold. It is necessary to carefully check the incoming wire, and eliminate the unqualified incoming wire in time. At the same time, it is necessary to check whether the pressing die is damaged and whether there are impurities, and repair and replace it in time.
