Problems solved by technology

In the patent literature with the publication number CN2528548Y, a mold painting device and its painting principle are disclosed, including a paint box, a mold base, a mold and a nozzle. On the paint box; when working, when the wire passes through the nozzle, the paint used for coating the wire is sprayed from the nozzle, and after the wire is painted, it passes through the mold fixed on the formwork to achieve the required coating thickness; using this method Structure, because the thickness and uniformity of the paint layer on the wire are controlled by the wire passing through the mold, so it is difficult to control the uniformity of the paint layer, prone to paint particles and pinhole defects, and the bond between the paint layer and the wire Low firmness, therefore, the electrical performance of the enameled wire is poor

Abstract

The invention discloses an enameled wire lacquering method, which comprises the following steps: firstly, passing drawn metallic conductors through a sink by setting out for cleaning; secondly, putting cleaned metallic conductors onto a lacquering device for lacquering, wherein ultrasonic wave sent by more than one ultrasonic vibrator is acted on the lacquering device in the process of the lacquering; and finally, roasting lacquered metallic conducting wires. The lacquering method can improve adhesion firmness of lacquering films on the conducting wires, eliminate partial lacquer particle phenomenon and pin holes on the lacquering films and improve the insulating property of the conducting wires; and simultaneously, ultrasonic wave has the function of eliminating stress of the metallic conductors without annealing processing of a softening furnace, and also has the function of reducing energy consumption.

Description

technical field [0001] The invention relates to a processing technology of enameled wire, in particular to a method for painting enameled wire. Background technique [0002] Existing coating processes for enameled wires include direct coating, felt, die coating, and resin extrusion. In the patent literature with the publication number CN2528548Y, a mold painting device and its painting principle are disclosed, including a paint box, a mold base, a mold and a nozzle. On the paint box; when working, when the wire passes through the nozzle, the paint used for coating the wire is sprayed from the nozzle, and after the wire is painted, it passes through the mold fixed on the formwork to achieve the required coating thickness; using this method Structure, because the thickness and uniformity of the paint layer on the wire are controlled by the wire passing through the mold, so it is difficult to control the uniformity of the paint layer, prone to paint particles and pinhole defec...
