Title (EN) BEAD RING AND METHOD FOR MANUFACTURING SAME
(FR) TRINGLE DE TALON ET SON PROCÉDÉ DE FABRICATION
(JA) ビードリング及びその製造方法
Abstract:
(EN) Provided is a bead ring in which the true strain, tensile strength, and yield strength of bead wires constituting the bead ring are set to specific ranges, whereby the processability during molding can be improved while minimizing production cost. Also provided is a method for manufacturing the bead ring. An annular bead ring 1 comprising bead wires 2 that have been subjected to a drawing process, wherein the bead wires 2 have a true strain ε of 2.80 or higher as calculated by formula (1), a tensile strength of 2000 MPa or higher, and a yield strength of 1700 MPa to 1980 MPa.
(FR) L'invention concerne une tringle de talon dans laquelle la déformation réelle, la résistance à la traction et la limite d'élasticité des fils de tringle constituant la tringle de talon sont réglées sur des plages spécifiques, moyennant quoi l'aptitude au traitement pendant le moulage peut être améliorée tout en réduisant au minimum le coût de production. L'invention concerne également un procédé de fabrication de la tringle de talon. Une tringle de talon annulaire 1 comprend des fils de tringle 2 qui ont été soumis à un processus d'étirage, les fils de tringle 2 ayant une déformation réelle ε d'au moins 2,80 telle que calculée par la formule (1), une résistance à la traction d'au moins 2 000 MPa, et une limite d'élasticité de 1 700 MPa à 1 980 MPa.
(JA) ビードリングを構成するビードワイヤの真歪、引張強度及び耐力を特定の範囲に設定することにより、生産コストを抑えながら、成形時の加工性を向上させることを可能にしたビードリング及びその製造方法を提供する。伸線加工が施されたビードワイヤ2からなる環状のビードリング1であって、ビードワイヤ2は、式(1)にて算出される真歪εが2.80以上であり、引張強度が2000MPa以上であり、耐力が1700MPa以上1980MPa以下である。
