Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 (a) shows the metal round wire processing apparatus 1 using one embodiment of the present invention (refer to image 3 ) processed metal round wire 100 (hereinafter referred to as "wire processed product") 100A. This processed wire product 100A is used, for example, as a power line of a motor or the like as disclosed in Patent Documents 1 and 2, and is formed to include connection parts 101, 101 connected to terminals and the like at both ends, and a plurality of bent parts 102, 102. , and the three-dimensional shape of the straight parts 103, 103 between the plurality of curved parts 102, 102. In addition, in the present embodiment, at any part of the processed wire product 100A, the diameter direction of the metal round wire 100 (the distance between the metal round wire 100 and the distance between the metal round wire 100) is formed within the range of the str...

Abstract

The present invention provides a round metallic wire rod that has of three-dimensional shape having prescribed dimensional accuracy and profile accuracy and having a cross-section non-circular part at a given portion without requiring additional processing. The invention is provided with a cross-section non-circular part-forming processing machine (20) for forming, at least at a portion of the round metallic wire rod, the cross-section non-circular part having a cross-section that is non-circular in an intermediate step for processing the round metallic wire rod into a predetermined three-dimensional shape. During bending, the cross-section non-circular part is bent into a given three-dimensional shape while being held by a wire rod holding part of a bending machine (30). By holding the cross-section non-circular part, the relative rotation between said cross-section non-circular part and the wire rod holding part is suppressed as compared with when the cross section is circular. Accordingly, the accuracy in bending a round metallic wire rod into a three-dimensional shape is improved.

Description

technical field [0001] The present invention relates to a processing method and processing apparatus for a metal round wire provided as a lead wire at a predetermined position of an electric device, and a method for manufacturing a power distribution component in which a resin member and a metal round wire are integrated. Background technique [0002] As lead wires for various electric devices, metal round wires composed of single wires having a circular cross section are used. A metal round wire is cheaper than a square wire with a square cross section, has excellent tensile and bending strength, and has advantages such as being easier to bend in a desired direction than a square when mounted on an electrical device. Focusing on such advantages, for example, in Patent Document 1, a metal round wire is used as a power line for supplying electric power to a three-phase rotating electric machine such as a motor. On the other hand, when three power lines are individually conne...
