本発明は、全屈等からなるニップルとゴムやプラスチッ
ク等からなる可撓性に冨むホースとを接Ｕ８する方θ：
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method U8 for connecting a fully bent nipple and a highly flexible hose made of rubber, plastic, etc.
It is related to.
従来、ニップルとホースを接続ずろ場合には、例えば実
開昭５８−６１９９３号のように、ニップルをホースに
挿入し、その外側に塑性変形可能な金属製筒体を配置し
、この筒体を外周から周方向に断続的にカシメて接続部
のシールを行っていた。Conventionally, when connecting a nipple and a hose, for example, as in Japanese Utility Model Application Publication No. 58-61993, the nipple is inserted into the hose, a plastically deformable metal cylinder is placed on the outside, and this cylinder is The joints were sealed by caulking intermittently in the circumferential direction from the outer periphery.
しかしながら、このような接続方法の場合には金属製筒
体を部分的に塑性変形させただけなので、経時的に変形
戻りを生じシール性を損なう虞れがあった。However, in the case of such a connection method, since the metal cylindrical body is only partially plastically deformed, there is a risk that the deformation returns over time and the sealing performance is impaired.
また、この変形戻りを防くため余りに強くカシメると、
接続部のボースの歪が大きくなってボースに亀裂等の損
傷が発生する欠点があった。Also, if you swage too strongly to prevent this deformation return,
There was a drawback that the strain in the connecting part of the bow increased, causing damage such as cracks to the bow.
本発明は上記の欠点に鑑みなされたもので、金属製筒体
の変形戻りを極力防止して、接続部の十分なシール性を
確保できるニップルとホースの接続方法を提供すること
を目的とするものである。The present invention was made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a method for connecting a nipple and a hose that can prevent the deformation of the metal cylinder as much as possible and ensure sufficient sealing performance of the connection part. It is something.

め伺りることを特徴とするものである。In order to achieve the above object, the connection method of the present invention involves inserting the connecting tube of the nipple into the bowse, covering the overlapping portion of the two with a rib that opens inward in the longitudinal direction (II'i), and After inserting the rigid rod into the rib, the base of the rib is caulked to cause the metal pipe to become compressed, and the rigid rod is held in the compressed state using a rake. While pulling out the rib from inside, the rib is exposed to the superhuman strength iiJ &
This method is characterized in that the boce at the polymerized portion is removed by crimping and crushing.
次ぎに本発明の一実施例を図面により説明する。Next, one embodiment of the present invention will be described with reference to the drawings.

嵌挿した状態を示している。Figures 1 and 2 show a connecting tube (2) of a metal nipple (1) inserted into a boss (3), which has a rib (5) in the longitudinal direction with an abbreviated cross-section that opens inward. A metal pipe (4) is placed outside the insertion part, and a 1% gold-enriched round bar (6) of a shape that matches the shape of the space is inserted into the inside of the rib (5).

The part marked =3 is formed to have approximately the same length as the pipe (l110) [,,,,.

押圧力を加えて押し潰すようにカシメを行う。In this state, a pressing force is applied to the roots (5a) and (+1.1)' of the ribs in the direction of the arrow in Fig. 2, 11, using the crimping tools (7) and (8), deforming the rib (51) by 10 casomes. Deform only the pipe +4.+ to reduce its diameter, and press the hose (3) to the connecting tube (2) of the nipple (1) and the pipe 14 over the entire circumference.Next, use the crimping tool (W).
, (8) are moved in the axial direction of the hose while being pressed against the bases (5a), (5a)' of the ribs, and the round rod (6) is pulled out from the rib (51. At the same time, the third As shown in Fig. 1, the ribs (5) are sequentially moved in the radial direction of the bose (in the direction of the arrow in Fig. ) Apply pressing force to crush it to swage it.
従って丸棒（６］がリブ（５）内から完全に引き抜かれ
たときには、リブ（５）は全長に亘って径方向に押し潰
されており、原形を全く止めていない訳である。Therefore, when the round bar (6) is completely pulled out from inside the rib (5), the rib (5) is crushed in the radial direction over its entire length and does not retain its original shape at all.
以」二述べたような本発明によれば、次のような効果を
奏することができる。According to the present invention as described below, the following effects can be achieved.

実かつ十分に円周方向に沿っζ引き。During the diameter reduction deformation of the full bending joint pipe by crimping in the first stage, a rigid rod is inserted into the rib space of the pipe and the base of the rib is crimped without reducing the volume of this space. Since I made it so that the ribs are not deformed at all, they are scary ([
Real and sufficient ζ pull along the circumferential direction.
寄−１られボースの全外周面に圧着でき、かつホースの
内周面をニップルの連結筒に密着させることができる。The hose can be pressed against the entire outer peripheral surface of the hose, and the inner peripheral surface of the hose can be brought into close contact with the connecting tube of the nipple.

るに至ったものである。In addition, while the nipple, hose, and pipe are kept in close contact with each other, the ribs of the pipe are crushed in the second stage of crimping, so there is no risk of the pipe returning or loosening after its diameter has been reduced. In addition to being able to maintain sufficient sealing performance even when the hose is used for a long period of time, the hose does not have to be pulled out, resulting in significantly improved durability.

In addition, in the case of Bose with unevenness on the outer surface, it is possible to fill in the recesses and make the outer surface approximately 1 illi+7.
The present invention may be applied later.
