のであった。[Prior Art] A hose engagement fitting is composed of an annular portion into which a hose is inserted and attached to the outer peripheral surface of the hose, and an engaging portion for engaging with another object. In a conventional hose engagement fitting, for example, one end of an elongated plate is rolled into a cylindrical shape to form an annular part, and the other end is used as an engaging part. In addition, the annular part and the engaging part were made by cutting, etc., and then welded and brazed into a U-shape to integrate them.

安があるものであった。When making an annular part by winding a thin plate material, there is a problem that the holding force is weak because it is not perfectly circular and slits are formed. Moreover, those made by cutting and then joining have high processing costs, are expensive, and there are concerns about the strength of the welded parts.

る。[Configuration 1 of the Invention The hose engagement fitting of the present invention has a bow inserted therein. The hose is made up of an annular part attached to the outer circumferential surface of the hose and an engaging part for engaging with another object, and the annular part is formed by draw-pressing a metal plate into a cup shape and then removing the bottom part. The engaging portion is formed on the flange portion during the drawing press forming.

に近い部分が厚く、他端側が薄肉となっている。In the hose engagement fitting of the present invention, the annular portion and the engagement portion are formed from a plate material by a press molding method. Then, the annular part is formed by drawing into a cup shape from one side to the other side by normal cup-shaped press forming, that is, drawing press forming, on the side near one end of the plate material, leaving the peripheral edge as a flange part and forming a bottomed cup. form. After forming to the specified depth,
The bottom part is punched out to form an annular part. For this reason, the annular portion of the hose engagement fitting of the present invention is thick at the portion near the flange portion and thin at the other end.

いないために比較的に肉厚である。The flange part is punched out appropriately, and finally punched out leaving the necessary filler allowance. At this time, an engaging portion is simultaneously formed in a part of the flange portion. The engaging portion is formed, for example, by providing an engaging hole. This engaging portion is relatively thick because it has not been subjected to drawing processing.

ている。[Effects of the Invention] The hose engagement fitting of the present invention can use a relatively thin plate material because the plate member is manufactured by press molding. For this reason, the hose engagement fittings themselves that are inevitably obtained are of a low quality. Further, the forming process is mainly performed by drawing and punching. For this reason, productivity is extremely high and manufacturing costs are extremely low. Therefore, it is possible to supply a large number of pairs at low cost. In addition, the engaging portion, which requires strength as a hose engagement fitting, and the flange portion of the annular portion connected to the engaging portion are portions that are not subjected to much processing such as drawing. For this reason, the thickness of the material is almost maintained, and compared to the other end of the annular part, the thickness can be maintained and the strength can be increased. The other end of the annular portion inevitably becomes thinner due to the drawing process, but there are fewer problems in terms of strength because the closer to the other end of the annular portion the less strength is required. In addition, the annular part often needs to be caulked, and in such cases, it is necessary to use a relatively thin wall that is easy to caulk.
It is preferable that the annular part is , and in this sense it is a suitable annular part.

。In this drawing process, the center part is drawn with a punch while holding down the part corresponding to the flange part. This drawing process is the same as the cup-shaped drawing process of normal cup forming. This first drawing process produced a state whose cross section is shown in FIG. Next, a second drawing process was performed to increase the diameter and depth of the cup shape, resulting in the shape shown in FIG. 5. Thereafter, the flange portion was trimmed, the outer circumferential surface of the engaging portion was punched, and holes were formed in the engaging portion to obtain the planar shape shown in FIG. 1. Finally, punch out the bottom part of Figure 5, and
This is the hose engagement fitting of this embodiment shown in the figure.

にホースを案内することも可能である。In this hose engagement fitting, a hose 3 is inserted into an annular part 1 as shown in FIG. The hose 3 is used by attaching a fitting to the curved part and holding the middle part of the hose. preferable. In special cases, as shown in FIG. 7, the nipple part 4 is inserted into the inner peripheral surface of the hose 3, and the annular part 1 of the hose engagement fitting held on the outer peripheral surface is caulked from the outer peripheral side. The hose 3 and the hose engagement fitting may be integrally fixed. Furthermore, it is also possible to guide the hose in an appropriate direction by bending the engaging portion 2 as required.

っている。Since the hose engagement fitting of this embodiment is formed by press forming using a relatively thin steel plate as a material, both the annular engagement portion and the engagement portion are relatively thin. For this reason, it is relatively light frl.
It is. In addition, the engaging part and the flange part of the annular part, which require strength, are not made thinner by press forming, etc., so they are thicker than other parts, and mechanically weaker than other parts. High strength. In particular, the engaging portion and the flange portion are portions on which large forces act, and are mechanically strong.
