Vertical annealing device for enameled wire

Abstract

The invention relates to a vertical annealing device for an enameled wire. The vertical annealing device comprises an annealing furnace and a cooling water tank. The annealing furnace is vertically arranged. An outlet of the annealing furnace is positioned at the bottom. Cooling water is contained in the cooling water tank, the cooling water tank is arranged at the bottom of the annealing furnace, and the cooling water tank is in sealed connection with the outlet of the annealing furnace. The cooling water tank is provided with a wire outlet. A bare wire enters the annealing furnace from an inlet of the annealing furnace, then enters the cooling water tank from the outlet of the annealing furnace, and is discharged from the wire outlet of the cooling water tank. According to the vertical annealing device for the enameled wire, when the bare wire is annealed, a high-temperature conductor makes contact with water in the cooling water tank to generate steam, the steam directly enters the annealing furnace, and therefore it is guaranteed that the annealed bare wire does not make contact with external air, and the situation that the surface of the bare wire is oxidized is avoided; and a steam generating device is not needed, heating is not needed, the high temperature generated in the annealing process of the conductor is reasonably utilized, a certain amount of ionized water is injected into the outlet position, and therefore steam is generated, and oxidation is prevented.

Description

technical field [0001] The invention relates to the technical field of enameled wire production devices, in particular to a vertical annealing device for enameled wires. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked for many times. Adaptability is not easy, it is affected by raw material quality, process parameters, production equipment, environment and other factors. Therefore, the special characteristic requirements of various enameled wires are different, but among them, "adhesion performance" is a very important performance index for enameled wire in winding composition. And some bare wires such as copper wires are easily oxidized after annealing and softening, and the oxide layer will cause obvious poor adhesion of the paint film. Therefore, the design ensures that the semi-finished part will not be oxidized after s...

Problems solved by technology

[0003] The solution for most annealing furnaces is to use water sealing or steam generating equipment at one end of the furnace mouth, but when the annealing furnace starts to work, there is less water vapor in the annealing tube, and the air cannot be removed in time, and the bare wire is prone to oxidation, which affects the annealing effect , thus affecting the normal painting and baking of enameled wire
