Description

Technical Field

[0001] The invention relates to an enameled wire, in particular to a processing technology and a processing device for an ultrafine enameled wire for a transformer. Background Art

[0002] At present, the processing technology used for enameled wire includes wire drawing, annealing, painting and oiling processes arranged in sequence, wherein the oiling process is to use a lubricating oil coating device to coat a certain amount of lubricating oil on the surface of the enameled wire, thereby making the surface of the enameled wire more lubricated and preventing it from being scratched and damaged during the subsequent winding and coiling process. On this basis, the existing lubricating oil coating device is mainly composed of a lubricating oil roller and a felt. When in use, the lubricating oil roller first rotates to coat the lubricating oil on the surface of the enameled wire, and then the felt is used to wipe the enameled wire, thereby removing excess lubricating oil on the surface of the enameled wire and evenly spreading the lubricating oil on the surface of the enameled wire.

[0003] However, the defect of this structure is that although the manufacturer can control the amount of lubricating oil applied to the enameled wire by adjusting the rotation speed of the lubricating oil roller, the amount of lubricating oil on the surface of the enameled wire after being wiped by the felt will be different from the predetermined amount of oil applied, which increases the difficulty for the manufacturer to adjust the amount of lubricating oil on the surface of the enameled wire. For example, when the amount of lubricating oil on the surface of the enameled wire increases, the amount of lubricating oil scraped off the enameled wire after passing through the felt also increases, and the lubricating oil retained on the felt will affect the subsequent enameled wire, resulting in inconsistent amounts of oil applied to the enameled wire. When the amount of lubricating oil on the surface of the enameled wire decreases, the felt can easily completely scrape off the lubricating oil on the surface of the enameled wire, or reversely apply the lubricating oil soaked in the felt to the enameled wire. Under the above limitations, it is difficult for existing lubricating oil coating devices to accurately control the amount of lubricating oil applied to the surface of the enameled wire.

[0004] The difference between transformer enameled wire and other enameled wires is that during the assembly process of the transformer, tape needs to be wrapped around the surface of the wound transformer enameled wire, so as to insulate, fix and protect the enameled wire with tape to ensure the stable operation of the transformer. This leads to the need to control the amount of lubricating oil on the surface of the transformer enameled wire within an appropriate range during the early coating, that is, on the one hand, the lubricity of the enameled wire needs to be ensured to prevent the enameled wire from being damaged by friction during processing, storage and winding, and on the other hand, the problem of the tape not being able to stick due to excessive lubricating oil needs to be avoided.

[0005] Therefore, it is difficult for manufacturers to control the amount of lubricating oil on the surface of the enameled wire to ensure the later use effect of the transformer enameled wire. Summary of the invention

[0006] The purpose of the present invention is to provide a processing technology and a processing device for ultra-fine enameled wire for transformers, which can improve the control effect of the amount of lubricating oil applied on the surface of the enameled wire.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0034] Embodiment 1. A processing technology for ultra-fine enameled wire for transformer, comprising the following steps:

[0035] ① Drawing, annealing, painting and baking the copper wire in sequence to obtain an enameled wire of a specified wire diameter, namely, enameled wire A;

[0036] ② Apply lubricating oil on the surface of copper wire A to obtain enameled wire B;

[0037] ③ Pass the enameled wire B through a wiping roller with a cleaning layer wrapped on the surface, and the wiping roller wipes the lubricating oil on the surface of the enameled wire B by rotating after the enameled wire B passes through, thereby removing excess lubricating oil on the surface of the enameled wire to obtain a finished enameled wire.

[0038] In the step ③, the rotation direction of the wiping roller and the running direction of the B enameled wire are set in the same direction or in the opposite direction. When the rotation direction of the wiping roller and the running direction of the B enameled wire are in the same direction, the faster the rotation speed of the wiping roller is, the more lubricating oil is applied to the B enameled wire after wiping, until the rotation speed of the wiping roller is consistent with the running speed of the B enameled wire; when the rotation direction of the wiping roller and the running direction of the B enameled wire are in the opposite direction, the faster the rotation speed of the wiping roller is, the less lubricating oil is applied to the B enameled wire after wiping.

[0039] In this embodiment, a wiping roller with a cleaning layer wrapped on its surface is used instead of the existing felt to wipe the enameled wire, so that the wiping roller can adjust the contact length of the enameled wire with the cleaning layer when passing through by changing its own rotation speed, thereby controlling the wiping effect of the wiping roller on the lubricating oil on the surface of the enameled wire and achieving control of the amount of lubricating oil applied.

[0040] Embodiment 2. A processing device, comprising Figure 1 and 2 As shown, it includes a wire drawing machine, an enameling machine and a lubricating mechanism connected in sequence, the wire drawing machine is used to perform electrical annealing and wire drawing on the copper wire, the enameling machine is used to paint and bake the copper wire, and the lubricating mechanism is used to apply lubricating oil on the surface of the enameled wire and wipe it;
