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

Abstract

The invention relates to a vertical annealing device for enameled wire, which comprises an annealing furnace and a cooling water tank; the annealing furnace is vertically arranged; Sealed connection with the outlet of the annealing furnace; the cooling water tank is provided with an outlet; the bare wire enters the annealing furnace from the entrance of the annealing furnace, enters the cooling water tank from the outlet of the annealing furnace, and then discharges from the outlet of the cooling water tank. The invention generates steam through the contact between the high-temperature conductor and the water in the cooling water tank during the annealing of the bare wire, so that the steam directly enters the annealing furnace, thereby ensuring that the bare wire after annealing will not be in contact with the outside air, and avoiding the oxidation of the surface of the bare wire; The present invention does not need to be provided with a steam generating device and does not need to be heated. The conductor is rationally used to generate high temperature during annealing, and a certain amount of ionized water is injected at the outlet to generate steam to prevent oxidation.

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...
