Softening treatment device used before enamelling copper enamelled wires

Abstract

The invention discloses a softening treatment device used before enamelling copper enamelled wires. The device comprises annealing chambers, wherein wire inlet holes are arranged at the wire inlet ends of the annealing chambers and copper wires enter the annealing chambers from the wire inlet holes. The device is characterized in that a plurality of parallel wire conduits are arranged at the wire outlet ends of the annealing chambers; the copper wires pass out of the wire conduits; the wire conduits incline downwards; a water tank is arranged in front of the wire conduits; a steam pipe is arranged above one end of the water tank; the lower ends of the wire conduits extend into the water tank; steam enters the annealing chambers; and the bare copper wires passing out of the wire conduits enter wire outlet pipes via wire wheels in the water tank. The device has the following advantages that the structure is improved ingeniously and simply, the high temperature steam is utilized to heat the passing bare copper wires and the temperature is uniform, so that the copper wires are softened uniformly and bubbles are greatly reduced after the copper wire surfaces are enamelled, thus ensuring the quality of the copper enamelled wires.

Description

technical field [0001] The invention relates to a processing device for bare copper wires on an enameling machine, mainly a softening processing device for copper enameled wires before enamelling. Background technique [0002] The annealing treatment required in the production of copper enameled wire is mainly to eliminate the phenomenon of cold hardening of the bare copper wire after wire drawing. During annealing, the high temperature in the annealing chamber heats the wire tube. The difference in temperature will lead to uneven softening of the bare copper wire, and the surface of the copper wire will have more foaming after painting, resulting in a decrease in the annealing effect; and in the prior art, the wire tube extending from the annealing furnace directly enters the cooling tank for cooling. The bare copper wire that has not been softened uniformly is cooled immediately, which destroys the overall performance of the bare copper wire. Contents of the invention ...

Problems solved by technology

[0002]Annealing treatment is required in the production of copper enameled wire mainly to eliminate the phenomenon of cold hardening after drawing bare copper wire. During annealing, the high temperature in the annealing chamber heats the wire tube. The technology is to use electric heating annealing in the annealing chamber. Due to the temperature difference of each position in the furnace body, the softening of the bare copper wire will be uneven, and the surface of the copper wire will have more bubbles after painting, resulting in a decrease in the annealing effect; and in the prior art, from The wire pipe protruding from the annealing furnace directly enters the cooling tank for cooling, so that the bare copper wire that is not softened and uniform is cooled immediately, which destroys the overall performance of the bare copper wire
