【考案が解決しようとする課題】 しかしながら、上記構成の継手金具は、加工数が少なく、また、どのような形 状の継手金具にも適用可能であり、安価に提供することができるものの、熔接面 が直接流体液に触れるという問題がある。即ち、ニップル突当面５１とフランジ 状接合部５５とは突当熔接されているために、接合部５７が透孔４４に面するこ とになり、直接、流体液に触れることになる。アセンブリ用継手金具、特に前記 例示のような高圧流体機器に用いられるアセンブリ用継手金具は、漏れを防止す るために継続的な高いシール性が要求される。そこで、接合部が透孔４４に面し て流体液に触れることはシール性の点からは好ましくないという問題がある。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, the fitting metal fitting having the above-mentioned configuration has a small number of processes, and can be applied to any shape fitting fitting, and although it can be provided at low cost, the welding There is a problem that the surface directly contacts the fluid. That is, since the nipple abutting surface 51 and the flange-shaped joint portion 55 are abuttingly welded to each other, the joint portion 57 faces the through hole 44 and directly comes into contact with the fluid. The fittings for assembly, particularly the fittings for assembly used in the high-pressure fluid equipment as exemplified above, are required to have high continuous sealing property in order to prevent leakage. Therefore, there is a problem that it is not preferable in terms of sealing property that the joint portion faces the through hole 44 and comes into contact with the fluid.
【０００５】 この考案はかかる現況に鑑みてなされたもので、熔接部分の強度とともに、高 いシール性が得られ安全に使用することができるホースアセンブリ用継手金具を 提供することを目的とする。The present invention has been made in view of the current situation, and an object thereof is to provide a joint fitting for a hose assembly, which has high strength of the welded portion and high sealing property and can be used safely.
【０００６】[0006]
この考案は上記目的を達するために次のような構成とした。即ち、分割成形し たスリーブ本体とニップル本体とを一体に固着してなるホースアセンブリ用継手 金具において、スリーブ本体は基部の一方側に接続部を形成し、他方側にスリー ブを設け、前記基部の軸心部にニップル挿通孔を穿設するとともに、前記接続部 側内面にニップル突当面を形成してなり、ニップル本体はニップルの一端にフラ ンジ状接合部を設けてなり、前記スリーブ本体のニップル挿通孔に前記ニップル を挿通してフランジ状接合部とニップル突当面とを一体に固着することを特徴と する。 The present invention has the following configuration in order to achieve the above object. That is, in a joint fitting for a hose assembly in which a sleeve body and a nipple body that are molded separately are integrally fixed, the sleeve body has a connecting portion formed on one side of the base portion and a sleeve provided on the other side thereof. A nipple insertion hole is bored in the axial center of the nipple, and a nipple abutment surface is formed on the inner surface of the connection portion side.The nipple body is provided with a flange-shaped joint at one end of the nipple, The nipple is inserted through the nipple insertion hole, and the flange-shaped joint portion and the nipple abutting surface are integrally fixed.

以下に、この考案を実施例に基づき詳細に説明する。図１はこの考案のアセン ブリ用継手金具の上半分を断面した側面図である。アセンブリ用継手金具は、ス リーブ本体１０とニップル本体３０とからなる。スリーブ本体１０は、外周面を 六角形ナットに形成した基部１１の一端側にメスネジからなる接続部１３を設け 、他端側にスリーブ１５を同心状に一体に設けてなる。前記基部１１の軸心部に はニップル挿通孔１７を穿設し、接続部１３側の側面を前記ニップル挿通孔１７ に対して直角面をなすニップル突当面１９とする。 Hereinafter, the present invention will be described in detail based on embodiments. FIG. 1 is a side view showing a cross section of the upper half of the assembly fitting of the present invention. The assembly fitting includes a sleeve body 10 and a nipple body 30. The sleeve body 10 has a connecting portion 13 formed of a female screw on one end side of a base portion 11 having an outer peripheral surface formed in a hexagonal nut, and a sleeve 15 concentrically integrally provided on the other end side. A nipple insertion hole 17 is formed in the axial center portion of the base 11, and a side surface on the side of the connection portion 13 is a nipple abutment surface 19 that is a plane perpendicular to the nipple insertion hole 17.
【０００９】 一方、ニップル本体３０はニップル３１の一端にフランジ状接合部３３を形成 してなり、スリーブ本体１０と同様に、鍛造または切削加工により成形される。 そして、前記スリーブ本体１０のニップル挿通孔１７にニップル本体３０のニッ プル３１を挿通し、ニップル突当面１９とニップル本体３０のフランジ状接合部 ３３の内側側面とをプロジェクション熔接または摩擦熔接により一体に固着して 組み立てられている。On the other hand, the nipple body 30 has a flange-shaped joint portion 33 formed at one end of the nipple 31, and is formed by forging or cutting similarly to the sleeve body 10. Then, the nipple 31 of the nipple body 30 is inserted into the nipple insertion hole 17 of the sleeve body 10, and the nipple abutting surface 19 and the inner side surface of the flange-shaped joint portion 33 of the nipple body 30 are integrated by projection welding or friction welding. It is fixedly assembled.
【００１０】 プロジェクション熔接を行うには、まず、前記ニップル突当面１９に低い突起 ２１を突設して置く。前記突起２１は環状に連続するものであってもよく、また 点線状に非連続に突設するものであってもよい。プロジェクション熔接は接続部 １３側からニップル挿通孔１７にニップル３１を挿通し、ニップル突当面１９の 突起２１にフランジ状接合部３３の内側を突き合わせて電流を流し、熔接温度に なったときに押圧して突起２１を潰して熔接すればよい。この熔接方法によれば 熱と加圧の集中がよく大きな接合強度が得られる。To perform projection welding, first, a low protrusion 21 is provided on the nipple abutting surface 19 so as to project. The protrusion 21 may be continuous in an annular shape or may be discontinuously provided in a dotted line. In the projection welding, the nipple 31 is inserted from the connection portion 13 side into the nipple insertion hole 17, the inside of the flange-shaped joint 33 is butted against the protrusion 21 of the nipple abutting surface 19, and an electric current is caused to flow to press it when the welding temperature is reached. The projection 21 may be crushed and welded. According to this welding method, heat and pressure are well concentrated and a large bonding strength can be obtained.
【００１１】 また、摩擦熔接を行うには、ニップル突当面１９とフランジ状接合部３３とを 押圧し、いずれか一方を回転させて摩擦熱によって適当な温度になったときに回 転を止め、同時に強い押圧力により接合すればよい。この接合方法によれば、接 合部の強度が大きく、異種金属や難熔接金属の接合も可能である。次いで、スリ ーブ本体１０の接続部１３にメスネジを刻設するとともに、フランジ状接合部３ ３の先端面を取り付ける機器のオスネジの先端接合面に合わせて切削加工すれば よい。To perform friction welding, the nipple abutting surface 19 and the flange-shaped joint portion 33 are pressed, and either one is rotated to stop rotation when the frictional heat reaches an appropriate temperature, At the same time, a strong pressing force may be used for joining. According to this joining method, the strength of the joined portion is high, and it is possible to join dissimilar metals and difficult-to-weld metals. Next, a female screw may be engraved in the connecting portion 13 of the sleeve body 10, and the tip surface of the flange-shaped joint portion 33 may be cut and processed in accordance with the tip joint surface of the male screw of the device to be attached.
【００１２】 上記実施例に係る継手金具を冷間鍛造と切削加工により製造する場合の方法に ついて説明すると、予めスリーブ本体１０とニップル本体３０とを分割して成形 する。まず、スリーブ本体１０の中間部品１０ａを成形する。図２に示すように 、冷間鍛造の方法により、基部１１の両側に接続部口１３ａとスリーブ１５を有 し、基部１１の軸心部にニップル挿通孔１７を穿設し、さらに、接続部口１３ａ 側の側面を前記ニップル挿通孔１７に直角面をなすニップル突当面１９とすると ともに、突起２１を設ける。一方、図３に示すように、冷間鍛造によりフランジ 状接合部３３を有するニップル本体３０を成形する。前記フランジ状接合部３３ は、仕上加工の切削のために厚肉に形成して置く。A method of manufacturing the joint fitting according to the above-described embodiment by cold forging and cutting will be described. The sleeve body 10 and the nipple body 30 are divided and molded in advance. First, the intermediate component 10a of the sleeve body 10 is molded. As shown in FIG. 2, by a cold forging method, the base portion 11 has a connection portion port 13a and a sleeve 15 on both sides, and a nipple insertion hole 17 is bored in the axial center portion of the base portion 11. The side surface on the side of the mouth 13a is used as a nipple abutment surface 19 which is a right angle surface with the nipple insertion hole 17, and a projection 21 is provided. On the other hand, as shown in FIG. 3, the nipple body 30 having the flange-shaped joint portion 33 is formed by cold forging. The flange-shaped joint portion 33 is formed thick and placed for cutting for finishing.
【００１３】 次いで、図４に示すように、スリーブ本体１０のニップル挿通孔１７にニップ ル本体３０のニップル３１を挿通し、ニップル突当面１９側にフランジ状接合部 ３３を位置せしめる。その後、ニップル突当面１９の突起２１にフランジ状接合 部３３を突当て、プロジェクション熔接、または摩擦熔接によって固着する。最 後に、接続部１３の形状を機器の取付部に合わせて切削加工すればよい。このよ うに、フランジ状接合部３３をスリーブ本体１０の接続部１３側で熔接すること により、熔接部はニップル３１の外側に位置することになるので流体液に直接触 れるのを防止することができる。尚、スリーブ本体１０の接続部１３の内面とフ ランジ状接合部３３の先端形状は固着前に形成しておいてもよい。Next, as shown in FIG. 4, the nipple 31 of the nipple body 30 is inserted into the nipple insertion hole 17 of the sleeve body 10 to position the flange-shaped joint portion 33 on the nipple abutting surface 19 side. After that, the flange-shaped joint portion 33 is abutted against the protrusion 21 of the nipple abutting surface 19 and fixed by projection welding or friction welding. Finally, the shape of the connecting portion 13 may be cut and processed according to the mounting portion of the device. By thus welding the flange-shaped joint portion 33 on the side of the connecting portion 13 of the sleeve body 10, the welding portion is located outside the nipple 31, so that it is possible to prevent direct contact with the fluid. it can. The inner surface of the connection portion 13 of the sleeve body 10 and the tip shape of the flange-shaped joint portion 33 may be formed before fixing.
