The surface of the copper-clad steel round wire shows hair or continuous scars on one side
1. The guide wheel material is rough and not smooth: when drawing thin wires, bakelite guide wheels are used.
2. The guide wheel rotates sluggishly: Do a good job in maintenance and check the operating status of the guide wheel frequently, such as whether there is shaking or stringing, etc., and replace it regularly.
3. The stretch cone wheel is grooved and worn: replace the cone wheel. The cone wheel is a relatively expensive accessory and should be properly maintained to extend its service life. Reasonable technology can improve the service life of the cone wheel, such as lubrication and reasonable mold matching technology.
4. The wire winding method on the cone wheel: Try to use less winding and no large winding to avoid scratching the copper wire with the mold frame or mold.
5. The structure of the guide wheel is unreasonable (such as multiple grooves in one): choose a guide wheel with multiple top grooves.
6. The incoming and outgoing wires are dug out of porcelain trenches, wire pay-off racks, etc.: wearing parts should be replaced regularly.
7. Poor lubrication and mold wear: adjust the lubrication density and replace the damaged mold.
8. The tension control is unstable and the relative slip is too large: A. The line speed and rotation speed can be checked through the line speed meter and compared; B. The single frequency conversion wire drawing machine can check whether the limit switch of the cone wheel is out of range.
9. Press the wire on the cone wheel in front of the processing mold: wind the wire back from the inside.
10. The annealed nickel ring is rough and grooved: replace the nickel ring.
11. The mold ratio is unreasonable and excessive slippage causes the wire to vibrate during startup: readjust the mold to reduce vibration.
