Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a gripping part for gripping a gripped body, which is one or a plurality of wirings or piping, on a metal fitting formed of a strip-shaped metal plate through an elastic body, and a support part that is fixed to a support at an end thereof. The present invention relates to a formed wiring / piping clip and a manufacturing method thereof.
[0002]
[Prior art]
An example of a conventional wiring / piping clip is indicated by C0 in FIG. A metal fitting 1A formed of a strip-shaped steel plate is provided with support portions S1 and S2 by providing screw insertion holes 2A and 2B for fixing to a support body (not shown), for example, a frame, at both ends thereof. The covered portion is provided with an elastic covering 8 to form a gripping portion H for gripping the wiring or piping. The support portions S1 and S2 at both ends are manufactured in a state of being opened by a springback, and are closely attached to each other by tightening screws when they are fixed to the support, thereby gripping the wiring or piping.
[0003]
In such a conventional clip C0, first, the metal fitting 1A shown in FIG. 10 is formed, and a plurality of metal fittings 1A in the illustrated example are inserted into the mold 20 as shown in FIG. The elastic coating 8 was molded.
Thus, since the conventional clip C0 covers the elastic body after the metal fitting 1A is molded, a large number of clips cannot be inserted into the mold 20 at once due to the shape of the clip C0, and there is a difficulty in reducing the cost by taking a large number. It was.

[Problems to be solved by the invention]
Accordingly, it is an object of the present invention to provide a wiring / piping clip and a method of manufacturing the same, which can be molded into a large number of elastic bodies at a time and can be easily manufactured.
[0005]
[Means for Solving the Problems]
According to the method for manufacturing a wiring / piping clip of the present invention, a gripping part (H) for gripping a gripped body via an elastic body (3) on a metal fitting (1) formed of a strip-shaped metal plate, and both ends thereof In the manufacturing method of the clip for wiring and piping in which a pair of support portions (S1, S2) fixed to the support is formed on the part, a metal fitting processing step for processing the plate-shaped rectangular metal fitting (1), and the metal fitting ( An elastic body molding step of integrally molding an elastic body (3) in which a plurality of 1) are arranged in a mold with their surfaces facing each other, and the metal fitting (1) is wrapped in the width direction in the mold (10); The metal fitting (1) integrally molded with the elastic body is taken out from the mold and the metal fitting (1) is bent to form one support (S2), and the metal fitting (1) integrally molded with the elastic body. Grip in which the grip part (H) is curved in advance before being attached to the gripped body And a forming step.
[0006]
The elastic body forming step includes a plurality of plate-shaped molds (1) that have a recess in which the metal fitting (1) and the elastic body material are accommodated, one more than the number of metal fittings (1) to be elastically molded. 10) It is preferable to arrange the metal fittings in the interior. .
[0007]
Further, the elastic body is formed in a plurality of columnar bodies (4) extending in the width direction of the metal fitting (1) and enclosing the metal fitting, and a gap is provided between the columnar bodies (4) adjacent to each other. preferable.
[0008]
Therefore, according to the present invention, the elastic body can be formed by arranging the metal plate on the mold so that the plate-like surfaces of the metal fittings face each other, so that a large number of molds can be formed at a time with a small mold.
In addition, the elastic body that grips the object to be gripped is formed of a plurality of columnar bodies, and a gap is provided between adjacent columnar bodies, so that the gripped portion can be easily formed into an arc shape, and the elastic body can be stressed. Can be reduced. Further, it is preferable to form a narrower width on the side of the object to be gripped, that is, on the inner side than the metal fittings of the columnar body because it can cope with a smaller diameter.
And since formation of a grip part is the last process, it can respond to various kinds of clips from which a pipe diameter and a support size differed from an elastic body formation state.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a clip C1 according to an embodiment of the present invention. The metal fitting 1 formed of a strip-shaped steel plate is provided with screw insertion holes 2A and 2B for fixing to a support body (not shown) at both ends thereof to form support portions S1 and S2. The screw insertion hole 2A shown in the figure is a long hole and can be adjusted, but it need not be a long hole.
[0010]
An elastic body 3 which will be described later is integrally formed in the gripping portion indicated by symbol H, and the molded shape is formed in an arc shape in accordance with the outer shape of the wiring or pipe which is the gripped body (not shown). This is performed after the elastic body 3 is integrally formed.
[0011]
Further, both end support portions S1 and S2 of the metal fitting 1 are formed in a state of being opened by a springback, and are brought into close contact with each other by tightening a screw when fixed to the support body, thereby gripping the object to be grasped.
[0012]
The elastic body 3 has a prismatic shape extending in the width direction of the metal fitting 1 formed of a strip-shaped steel plate, and is composed of a plurality of, in the illustrated example, six columnar bodies 4 formed around the edge of the metal fitting 1. In the embodiment of FIG. 1, these columnar bodies 4 are connected to each other by a connecting portion 5. And the to-be-held body side, ie, the inside, from the connecting portion 5 is narrowed in the circumferential direction as it approaches the to-be-held body, and is formed so that it can be easily formed into an arc shape.
[0013]
It should be noted that it is preferable to provide the metal fitting 1 with a hole 6 as shown in FIG. 4 because the elastic body 3 and the metal fitting 1 are firmly fixed and the columnar body 4 of the elastic body 3 is connected to each other.
[0014]
In the embodiment shown in FIG. 2, the shape of the elastic body 3 </ b> A is different, and is fixed around the width of the metal fitting 1 only by the columnar body 4, and is not connected to each other or connected only by the metal fitting width. Therefore, it can be more easily formed into an arc shape.
FIG. 3 shows an embodiment in which the shape of the columnar body 4B of the elastic body 3B is wider than that of the above-described embodiment and is formed by three.
[0016]
Next, a manufacturing method will be described.
First, the metal fitting 1 shown in FIG. 4 is plate-shaped, and the screw insertion holes 2A, 2B and the like are subjected to, for example, blank piercing (metal fitting process).
[0017]
Then, as shown in FIG. 5, a plurality of the plate-like metal fittings 1, 11 in the example shown, are inserted into the mold 10, and the plate-like surfaces are arranged facing each other to form the elastic body 3. Molding is performed to integrally form the metal fitting 1 and the elastic body 3 (elastic body molding step).
[0018]
In this way, as shown in FIG. 6, the metal fitting 1 and the elastic body 3 are taken out from the mold 10 in a state D in which the metal fitting 1 and the elastic body 3 are integrally formed, and the gripping portion H is formed into a predetermined shape shown in FIG.
[0019]
This manufacturing method can also be applied to molding of clips C4 and C5 in which the shapes of the elastic bodies 3C and 3D are integrated as shown in FIG. 7 or FIG.
[0020]
【The invention's effect】
The present invention is configured as described above and has the following effects.
(1) Productivity is improved because a large number can be molded simultaneously.
(2) When a columnar elastic body is formed by wrapping a metal fitting, no adhesion is required.
(3) The elastic body is formed of a plurality of columnar bodies having gaps between each other, and can be easily molded with little generation of stress accompanying bending even for a small tube diameter. In particular, if the inner diameter side of the columnar body is formed narrow, interference can be prevented and a smaller diameter can be accommodated.
(4) Since the formation of the grip portion is post-processing, it can be used for clips having various pipe diameters and different support dimensions.
