Automatic varnishing method for wire rods of enameled wires

Abstract

The invention belongs to the enameled wire processing technical field and relates to an automatic varnishing method for the wire rods of enameled wires. According to the step 1 of the method of the invention, a wire rod is inspected, so it can be ensured that the wire rod is free of quality defects such as wire fracture, bump-cased damage and scratches; and strengthening quality management is enhanced to reduce the influence of other factors on varnishing quality. According to the step 2 of the method, the wire rod passes through an ash removal module, a varnishing module, a layer-uniformizingmodule and a drying device sequentially. According to the step 3, the rotation speed of the ash removal module ranges from 50 to 100 rpm, and it is advisable that the surface of the wire rod should be cleaned until the surface of the wire rod is smooth and is free of dust and oil spots; the parameters of the varnishing module are set so as to automatically match the diameter of the wire rod, andit is advisable that the number of turns of the rotation of a varnishing ring around the wire rod to varnish the wire rod should be 60 to 80 turns per minute; and the layer-uniformizing module is adjusted, so that coating thickness error can meet the requirements of customers. According to the step 4, after the wire rod is inspected as a qualified product, batch production is carried out. According to the automatic varnishing method for the wire rods of the enameled wires of the invention, the above varnishing devices are adopted, the surface coating of the wire rod is uniformized, and therefore, the uniformity of the coating can be improved, and the insulation quality of the wire rod can be improved.

Description

technical field [0001] The invention belongs to the technical field of enameled wire processing, in particular to an automatic varnishing method for enameled wires. Background technique [0002] Enameled wire is a main variety of winding wire. It consists of conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but all have Mechanical properties, chemical properties, electrical properties, thermal properties of four properties. [0003] Painting is the process of applying enameled wire paint to metal conductors to form a uniform paint layer with a certain thickness. In the existing painting method, the thicknes...

Problems solved by technology

In the existing painting method, the thickness of the paint film is not easy to achieve uniformity, and it is easy to cause the paint film to be eccentric; the uniformity of the paint film thickness directly restricts the insulation performance of the wire; at the same time, for wires with different diameters, different specifications are used Mold method, which has low production efficiency
