Description

Technical Field

[0001] The present application relates to the technical field of enameled wire production, and in particular to a non-contact annealing furnace for cables. Background Art

[0002] Annealing of enameled wire is to heat the wire material to a certain temperature and keep it for a period of time, and then slowly cool it down to rearrange the crystal structure inside the wire material, thereby improving its mechanical properties and electrical conductivity. The annealing temperature and time are determined according to the type of wire material and the required performance.

[0003] For example, a Chinese patent application number 201710515960.5 discloses an annealing furnace device for an enameling machine, comprising a base, a bracket, an annealing furnace and a plurality of annealing tubes for passing the enameled wire and bare wire. The annealing furnace is fixed to the base by the bracket, and the plurality of annealing tubes respectively pass through the wire inlet end of the annealing furnace, pass through the inner cavity of the annealing furnace, and pass out from the wire outlet end of the annealing furnace. An anti-oxidation device is provided on the base in front of the wire inlet end of the annealing furnace. A fan and a heating box are provided at the upper left end and the lower right end of the annealing furnace. The air outlet of the fan is connected to the heating box. A heating device is provided in the heating box. The outlet of the heating box is connected to an air outlet ring arranged in the annealing furnace through an air outlet pipe.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] During the production process, the surface of the enameled wire will frequently contact with parts such as the wire wheel during transportation, so it is inevitable that more grease will adhere to the surface of the enameled wire. These greases will evaporate at high temperature during the heating and annealing process in the annealing tube. When the annealing furnace is not in use, the vaporized grease will re-condense onto the inner wall of the annealing tube. Long-term use will reduce the thermal energy utilization rate of the annealing tube, greatly reducing the service life of the annealing tube. Utility Model Content
