Title:
METHOD FOR PROCESSING ROUND METALLIC WIRE ROD, APPARATUS FOR PROCESSING ROUND METALLIC WIRE ROD, AND PRODUCTION METHOD FOR POWER DISTRIBUTION COMPONENT
Document Type and Number:
WIPO Patent Application WO/2021/079681
Kind Code:
A1
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 present 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.
