Description
請求項１の発明は、磁石体と、該磁石体を収納する凹所を有すると共に軟磁性ステンレス鋼よりなるヨークと、上記磁石体を封入するよう上記ヨークの凹所開口部に配設されたシールプレートとよりなり、
該シールプレートは、軟磁性ステンレス鋼よりなるシールド板と、該シールド板の外周に接合した非磁性ステンレス鋼よりなる非磁性リング部とよりなり、
また、上記シールド板と非磁性リング部と上記ヨークとの間は、その表面側が一度で一体的に溶接された溶接部を有することを特徴とする義歯アタッチメントにある。
The invention according to claim 1 comprises a magnet body, a yoke having a recess for housing the magnet body and made of soft magnetic stainless steel , and a recess opening of the yoke so as to enclose the magnet body. Composed of seal plate and
The seal plate comprises a shield plate made of soft magnetic stainless steel , and a nonmagnetic ring portion made of nonmagnetic stainless steel joined to the outer periphery of the shield plate.
A denture attachment is characterized in that a weld between the shield plate, the nonmagnetic ring portion, and the yoke has a surface welded integrally at one time .
上記シールプレートにおいて、上記シールド板に用いる軟磁性材料としては、１９Ｃｒ−２Ｍｏ−０．２Ｔｉ−Ｆｅ、１７Ｃｒ−２Ｍｏ−０．２Ｔｉ−Ｆｅ、１３Ｃｒ−２Ｍｏ−０．２Ｔｉ−Ｆｅなどがある。
また、非磁性リング部に用いる非磁性材料としては、ＳＵＳ３０４、ＳＵＳ３１６、３１６Ｌ、３１０Ｓ等のステンレス鋼がある。
シールド板と非磁性リング部の接合に関しては後述の製造方法において説明する。
In the seal plate, as soft magnetic materials used for the shield plate, there are 19Cr-2Mo-0.2Ti-Fe, 17Cr-2Mo-0.2Ti-Fe, 13Cr-2Mo-0.2Ti-Fe, and the like.
In addition, as nonmagnetic materials used for the nonmagnetic ring portion, there are stainless steels such as SUS304, SUS316, 316L, and 310S.
The bonding of the shield plate and the nonmagnetic ring portion will be described in the manufacturing method described later.
次に、クラッド棒をスライス切断して薄板状のシールプレートとする。シールプレートの厚みは、上記のごとく、０．０５〜０．４ｍｍとすることが好ましい。
また、シールプレートの非磁性リング部とヨークとの間の接合方法としては、レーザー溶接、電子ビーム溶接などがある。
Next, the clad rod is sliced to form a thin seal plate. As described above, the thickness of the seal plate is preferably 0.05 to 0.4 mm.
Further, as a method of joining the nonmagnetic ring portion of the seal plate and the yoke, there are laser welding, electron beam welding and the like.
