Description

Technical Field

[0001] The utility model relates to the field of purple copper wire production, in particular to a continuous drawing and annealing production line for purple copper wire. Background Technique

[0002] The continuous drawing and annealing production line for purple copper wire is a professional metal processing production line. Its main function is to continuously draw and anneal purple copper wire. In this process, first, the purple copper wire is released by a wire pay-off machine and then enters a drawing box. Under the combined action of multiple winding wheels and drawing dies, continuous drawing is carried out, so that the purple copper wire reciprocally winds in the winding grooves of small wheels and large wheels and is gradually stretched and refined. Subsequently, the drawn purple copper wire will enter an annealing furnace for annealing treatment. The contact wheel in the annealing furnace heats the copper wire to 500 - 550 degrees through electrical contact and then naturally cools. This can effectively eliminate the internal stress of the copper wire, thereby improving its plasticity and electrical conductivity.

[0003] When the existing continuous drawing and annealing production line for purple copper wire is performing annealing operations, since the purple copper wire is prone to high temperature and black smoke at the feeding port when entering the annealing furnace for annealing treatment, the drawing rollers will be roasted and blackened at this time, which may lead to the following safety hazards. For example, the drawing rollers may be damaged due to high-temperature roasting, affecting their service life and performance, and may even be deformed or cracked. At the same time, the blackened drawing rollers may leave black marks on the copper wire. Coupled with the attachment of pollutants in the high temperature and black smoke, the quality of the copper wire will decline. In addition, frequent cleaning and maintenance of the smoked black drawing rollers will increase the downtime and reduce the production efficiency. Moreover, the high temperature and black smoke also pose a threat to the health of employees and may cause safety accidents such as fires. Especially when the black smoke contains flammable substances, the risk is more significant. Summary of the Utility Model
