【産業上の利用分野】本発明はネジ部とその他の部分と
で硬度が違うホース口金具に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose mouth fitting having different hardness between a screw portion and other portions.

ている。2. Description of the Related Art A hose mouth fitting is composed of a socket portion for inserting an end portion of the hose and crimping and deforming an outer cylinder portion, and a screw portion having a screw portion for connecting the hose to a device.
【０００３】このホース口金具としては、冷間鍛造加工
により成形したものが多く使用されている。As the hose mouth fitting, one formed by cold forging is often used.

【発明が解決しようとする課題】しかしながらホース口
金具はソケット部にホースを挿入し加締め変形させるた
め、外筒も内筒もある一定硬度以下でないとソケット部
に割れ等を生じる恐れがある。However, since the hose mouthpiece inserts the hose into the socket part and deforms by caulking, the socket part may be cracked unless both the outer cylinder and the inner cylinder have a certain hardness.
【０００５】これを解決するために、ホース口金具に焼
鈍を施したり、抵硬度の材料を使用した場合にソケット
の変形性は良くなるが、ネジ部の硬度も低くなるために
機械的に弱く、相手部品の締め付け時等に強度が低下し
ネジ部の破損や、シール部への応力伝達が出来ないため
に液漏れが生じ易い欠点があった。In order to solve this, when the hose mouth fitting is annealed or a material having a low hardness is used, the deformability of the socket is improved, but the hardness of the screw portion is also low, so that it is mechanically weak. However, the strength of the mating component is reduced when it is tightened, and the thread portion is damaged, and stress cannot be transmitted to the seal portion.
【０００６】本発明の目的は、前記の欠点を解消し、ソ

への加締性能を向上し、ネジ部強度を大幅に向上させた
ものである。SUMMARY OF THE INVENTION The gist of the present invention is a hose mouth fitting which is made of the same material but has a high hardness of the screw portion and a low hardness of the socket portion, thereby improving the crimping performance to the hose. The screw strength is greatly improved.

ト部の硬度が１０００ｇ荷重による微小硬さにして９０
〜１２０ＨMV、前記ネジ部の硬度が同じく１２０〜１５
０ＨMVであることが好ましい。That is, the above object of the present invention is solved by a hose fitting comprising a socket portion and a screw portion, wherein the hardness of the socket portion is lower than the hardness of the screw portion. . At that time, the hardness of the socket portion is set to a minute hardness of 90 g under a load of 90 g.
~ 120HMV, the hardness of the thread is 120 ~ 15
It is preferably 0HMV.

鈍する方法等が挙げられる。As a concrete method for lowering the hardness of the socket portion than the hardness of the screw portion of the present invention, the entire hose fitting is initially made to have the hardness of the screw portion, and then only the socket portion is heated and annealed to soften the hardness. Let it form. Examples of the method of partial annealing include a method of heating and annealing the socket portion side while cooling the screw portion side.

硬度測定点としては４において行う。In the hose fitting including the screw portion 1 and the socket portion 2, the strength of the screw portion 1 is maintained at 120 to 150 HMV and the hardness of the socket portion is maintained at 90 to 120 HMV.
Initially, the entire hose fitting was manufactured with a hardness of 120 to 150 HMV in the screw part, and then only the socket part 2 was heated and annealed.
Lower the hardness of that part. At that time, the hardness measurement point is 3 at the screw hardness measurement point, and the socket hardness measurement point is at 4.
【００１２】同様にネジ部１が異なる図２に示すホース
口金具の場合も、図１と同様に硬度測定点を３、４で示
す。Similarly, in the case of the hose fitting shown in FIG. 2 in which the threaded portion 1 is different, hardness measurement points 3 and 4 are shown as in FIG.
