Bending of copper wire means that the surface of the copper material has a bamboo-like shape or the surface of the copper material has a twist of a predetermined pitch. The feeling that the surface of the copper material is not lubricated or not straight is felt by hand. The Kunshan slow wire is laid. The phenomenon that the line is looped and causes the knot to be knotted is commonly called large bending; the two phenomena are collectively referred to as bending.

Causes and avoidance measures:

1. The tension is unstable and the fluctuation is large: report to the equipment department for maintenance, adjust the tension spring, and adjust the tension weight.

2. The mold and the wire are not horizontally entangled in the same axis, causing the wire to be unstraight: adjust the position of the mold base.

3. The mold sizing area is too short or the mold is too loose: adjust the mold.

4, the wire drawing machine vibration: report to the equipment department for maintenance.

5. The guide wheel is slotted, strung or inflexible: check and change regularly.

6. Fixed speed wheel pressure line head: stop adjustment.
