Abstract

PURPOSE:To perform peeling with high yield by deforming only the defective portion existing on the surface of linear material into oval shape then cutting the portion at the long diameter portion by means of a peeling dies. CONSTITUTION:Linear material (a) is deformed into oval shape between the rolls 5 having oval grooves. The surface portion at the long diameter side is cut by desired amount through a peeling dies 6 having circular holes of approximatey 0.1-0.2mm. diameter which is longer than the diameter (8mm.phi) of rough- drawn wire (a) prior to deformation, then it is taken by a double deck wire expander 7 and wound by continuous wire expander 8, finish capstan 9 and defect searching machine 12 to finish into a roughly-drawn wire having smooth surface.

[Detailed Description of the Invention] The present invention is a method for automatically removing surface defects of rough drawn wires produced by casting in the rolling process in long wire rods such as copper wires, aluminum wires, or alloy wires thereof. This invention relates to an improvement in a peeling method that summarizes surface properties.

BACKGROUND ART Conventionally, copper wires, aluminum wires, or alloy wires thereof (hereinafter referred to as wire rods) are required to have strict surface quality control due to their usage conditions. For example, in copper wire for enamelled wire, the presence of protrusions such as ridges reduces the dielectric strength of the enamelled wire, so their removal has become an essential issue.

However, this method of stripping involves stripping the entire length of the wire and the surface of the wire, which means that even areas without defects are removed, resulting in a significantly poor yield rate and the need to strip the wire at a certain thickness. Lacking any more depth to do this:
The defect of the present invention is that it leaves 9 scratches in the recessed areas. In view of this situation, the present invention has been developed as a result of intensive research and has improved the yield by peeling only the defective areas. We have developed a method for stripping wire that automatically strips the wire to the appropriate thickness, making it possible to control the quality of the wire over its entire length. That is, the method of the present invention detects a surface defect on a running wire using a flaw detection device, processes the defect signal displayed by a computer to calculate the position and depth of the defect, and then calculates the position and depth of the defect. depending on,
A predetermined grooved roll group of a grooved roll group in which a desired number of pairs of elliptical grooved rolls having different angles are arranged in series is operated, and the defective part is located at the end of the major axis of the elliptical roll. The method is characterized in that after the wire is deformed into an elliptical shape, the longer diameter side portion of the wire is subsequently cut using a peeling die.

本発明方法の1例を図面により詳細に説明する。An example of the method of the present invention will be explained in detail with reference to the drawings.
