Description

***** machine works to draw Φ8mm copper rod into copper wire ranging from Φ1.**4.0mm and further softens the wire by direct annealing, and then the wire is taken up into Φ**0 or Φ**0 bobbin by dual spooler or coiler by Φ**0 coiler. The product conforms to the the requirements of the Chinese National Standard GB***3. 2. This machine is from the latest design, so it is good in look, advanced in construction, and produces little noise in running, and able to achieve high performance. ***** drawing capstans, the final capstan and the guide pulley are treated with tungsten carbide, so they have high hardness, high wearability, and a long service life; ***** main motor of the main machine, motor of the final capstan, and motor for take-up are all controlled by fully digital DC speed regulators, which can achieve high precision in speed regulati on; ***** annealer is of horizontal type in two sections performing continuous annealing by direct current, so it is particularly suitable for low-oxygen copper rod from scraps, as it softens the wire completely, and is rational in construction and easy in operation. Fully digital control board is used in the annealing process, so it is able to achieve high precision and stability. The digitalized adjustment of the annealing current and the automatic follow-up of the annealing voltage make it possible to produce wire at high and stable quality so that the wire always retains constant elongation at start-up, shutdown and continuous running, able to achieve zero-length annealing, ***** there is no non-annealed wire on the bobbin from start to finish; 5.
