After the welding, the hose joint with bracket is usually subjected to surface treatment such as galvanization (because the surface treatment is destroyed by welding), and further, the hose 1 and the caulking device are caulked and fastened. It was

[0005]

[Problems to be solved by the device]

 However, when the above-mentioned spot resistance welding is used to integrate the mounting bracket into the joint body, there are the following problems.

(1) Depending on the shape of the flange portion of the joint body, a sufficient distance cannot be provided between the spots, and a phenomenon of current flow occurs, which is a phenomenon of dynamic flow, resulting in stable joint strength by spot welding. It is difficult to get between the joint body and the mounting bracket.

(2) Even when the material forming the joint body and the mounting bracket is a dissimilar metal material (for example, brass and steel), sufficient welding strength can be obtained by spot welding between the joint body and the mounting bracket. Hard to get.

(3) At the end of the hose, when the joint and the hose are fastened, the work is done with the bracket attached, so the fastening work is difficult and a special device is required.

In view of the above, the present invention provides stable coupling strength between the joint flange portion and the mounting bracket regardless of the shape of the flange portion of the joint body, and It is also an object of the present invention to provide a hose joint with bracket in which the mounting bracket can be integrated into the joint body after caulking and fastening the joint body and the hose body. .

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the drawings, the same parts as those in the conventional example are designated by the same reference numerals, and the whole or part of the description thereof is omitted.

(1) A joint to be caulked and fastened to the hose main body 1, wherein the joint main body 3 and a mounting bracket 7A made of sheet metal are integrated via a flange portion 5, and the mounting bracket 7A Is a holding hole 9 that is engaged with the flange portion 5 of the joint body 3 and can be inserted from at least one side of the joint body 3 (the female thread portion 6 side in the illustrated example), and an engagement hole 13 that can engage with a mating member. It is equipped with. Up to this point, the configuration common to the above-mentioned conventional example is provided.

(2) In this embodiment, as shown in the drawing, the flange portion 5 of the joint body 3 is locked by the receiving and locking bent portion 21 formed at the lower end of the mounting bracket 7A, and the flange portion 5 is Both sides are bent and sandwiched by the sandwiching plate portions 23, 23 formed on both sides of the mounting bracket 7A by bending, and the mounting bracket 7A is integrated with the joint body. The amount L of overlap between the sandwiching plate portion 23 and the flange portion 5 due to this bending is usually 1 to 3 mm. If it is less than 1 mm, it may be difficult to secure the bonding strength.

Here, as the mounting bracket 7A, for example, one formed by punching and bending from a sheet metal of stainless steel or aluminum, which does not require anticorrosion treatment, by a press is used. The joint body 3 is made of a pipe material by forging and is surface-treated with zinc plating or the like. Further, the plate thickness of the mounting bracket 7A is usually 0.5 to 2 mm in the case of a steel plate, for example.

(3) Next, a method for manufacturing a vehicle hose using the joint with bracket will be described.

First, the joint body 3 is fastened to the hose body 1, and the sleeve portion 4 of the joint body 3 is swaged by a swaging device. At this time, since the mounting bracket 7A is not yet joined to the flange portion 5 of the joint body 3, the caulking and fastening work can be easily performed without using a special caulking device.

Next, the mounting bracket 7A is inserted into the joint body 3 through the holding hole 9 from one side of the flange portion 5 (the female screw portion 6 side), and the upright holding plate portion 23 is pressed. The flange portion 5 of the joint main body 3 is clamped by bending the joint body 3 and the like. This bending process may be performed by a pressing device, but can be easily performed by a tool such as pliers.

As a result, the flange portion 5 of the joint body 3 is supported at its lower end by the receiving and locking bent portion 21 and is sandwiched on both sides by the sandwiching plate portions 23, 23, so that the mounting bracket 7A and the joint body 3 are sandwiched. 3 is integrated via the flange portion 5 of the joint body 3.

(4) The technical scope of the present invention is not limited to the above embodiments. For example, when the holding force of the holding plate portion 23 with respect to the flange portion 5 is large, the receiving and locking bent portion 21 is not necessary. Further, as shown in FIG. 6, the disc-shaped flange portion 5A may be sandwiched between the sandwiching plate portions 23A, 23A arranged on the mounting bracket 7B in the tangential direction below the flange portion 5A.

[0021]

[Operation and effect of the device]

 The hose joint with bracket of the present invention has the following actions and effects due to the above-mentioned configuration.

(1) Since the joint body and the mounting bracket are integrated by sandwiching the flange portion of the joint body by bending the sandwiching plate portion, spot welding becomes unnecessary and the commutation phenomenon associated therewith occurs. It never happens. Therefore, stable coupling strength can be obtained between the flange portion of the joint body and the mounting bracket regardless of the shape of the flange portion of the joint body.

(2) For the same reason as above, that is, because the mounting bracket is fixed to the joint body by bending, even if the material forming the joint body and the mounting bracket are different metal materials, sufficient bonding strength is obtained. Is obtained. Therefore, the combination of metallic materials for the joint body and the mounting bracket is also optional. That is, as a material for the mounting bracket, a material such as stainless steel or aluminum which does not require plating and is difficult to weld can be used. In addition, since a material such as stainless steel or aluminum that does not require plating can be used in the post-processing, there is no problem of plating failure.

(3) Since the plating after integrating the mounting bracket and the pre-plated joint body is unnecessary, the mounting bracket can be integrated into the joint body even after the joint is fastened to the hose. When connecting to the hose, it is not necessary to do so with the bracket attached. Therefore, no special device is required for fastening the hose body and the joint.

It should be noted that Japanese Utility Model Laid-Open No. 60-178690 discloses a technique in which a mounting bracket is joined by caulking a thick portion formed continuously with a base flange portion. In this case, the flange portion is disclosed. Since the joint shape is limited, such as when the mounting bracket is thickened, and there is a risk of plating failure when the mounting bracket is caulked to the base flange portion, plating is required even after the integration. When attaching the fitting body to the hose, it must be fastened with the mounting bracket attached. Therefore, the fastening work also requires a special tool and cannot completely solve the problems of the prior art of the present invention.
