Description

[Detailed description of the invention] This invention relates to a fixing fitting tightening device for tightening and fixing a fixing fitting that holds together several long rod-like bodies such as pipes and electric wires. It is.

Conventional flat pipe fixing fittings with claws and holes on both ends are tightened using radio pliers, etc.
Fixation after tightening was carried out by bending pre-molded claws. However, all of this work was done by hand, which caused problems in terms of occupational health, such as poor work efficiency and the formation of blisters on the palms of the hands.

This invention eliminates the drawbacks of the prior art mentioned above,
The purpose of this device is to provide a pipe fixing fitting tightening device that can bend, tighten, and fix fixing fittings in one operation. A holder that receives a fixing metal fitting with claws and holes at both ends in a U-shaped curve so that the holding body can be placed on the surface, and the metal fitting is bent in one motion, tightened, and fixed. This device includes a reciprocating pressing mechanism that has a pressing portion on the forward end side, and is capable of reciprocating movement.

Hereinafter, one embodiment of this invention will be described with reference to the drawings. In FIG.
The fixing fitting 4 is a flexible flat plate having a hole 3 into which the hoses 5 can be inserted; A shock absorbing rubber holder having a cross-sectional shape of spectacles having a smaller outer diameter at the center than at both ends; 6 is a holder for receiving the fixing fitting 1, which characterizes a part of this invention, in a U-shaped curve; In this case, the surface has a concave structure with a substantially semi-elliptical cross section to fit the outer periphery of the rubber protector 4 that holds the two pipes 5, 5 together. 7 is a reciprocating linear movement that moves in a direction perpendicular to the longitudinal direction of the pipes 5, 5 and connects the ends of the fixing fittings by pressing the side surface of the fixing fitting 1 forming a U-shape. In this case, the mechanism includes a box-shaped air cylinder 10 that can reciprocate the outer periphery of the rod 9 fixed on the table 8 along its longitudinal direction, and a rear end on the top of the air cylinder 10. A rigid metal plate 11 is fixed integrally with the metal plate 11, and in this case, a shaft 12 is fixed to the distal end side of the metal plate 11, the distal end of which is formed in a concave shape, and the shaft 12 is provided with a fixing fitting. A first pressing section 13, 1 consisting of two bearings rotatably fixed with an appropriate gap between which only the other end of the first pressing section 13, 1 is pressed (and bent at the same time).
3 and a second pressing part 14 formed slightly behind the first pressing part 13 and consisting simply of a protrusion formed on the lower surface of the metal plate 11 in order to bend the protruding claw 2. is a formed structure. The above-mentioned pedestal 6
A device in which this pressing mechanism 7 is combined is the pipe fixing fitting tightening device of this invention.

The metal fitting tightening device constructed as described above operates according to the following sequence of operations to integrate the pipes 5, 5. That is, first, as shown in FIG. 1, two pipes 5, 5 are held in advance by a rubber holder 4 made of two halves, and then tightened along the outer periphery of the lower surface of the rubber protector 4 with a small outer diameter. With the attachment fitting 1 applied, it is pushed into the pedestal 6 and arranged.

In this case, the pedestal 6 has an almost semi-elliptical concave structure corresponding to the outer peripheral surface of the rubber protector 4, so when placed, the metal fitting 1 is shaped into an almost U-shape due to the pressing force. transformed. Next, in this case, one end side (the side with the claw 2) of the metal fitting 1 is bent slightly along the outer peripheral surface of the rubber protector 4 with only the claw 2 protruding in the vertical direction, and then the pressing mechanism 7 is bent. Part of the air cylinder 10 is operated. When the air cylinder 10 operates, the air cylinder 10 moves along the longitudinal direction of the rod 9,
That is, the metal plate 11 is moved forward toward the receiving table 6, and at the same time, the metal plate 11 is also moved. As the metal plate 11 advances further, the bearings 13, 13, which are the first pressing portions at the tip of the metal plate 11, come into contact with the side surface of the other end of the metal fitting 1, as shown in FIG. 2, and as the metal plate 11 advances further, as shown in FIG. In this way, the other end of the metal fitting 1 is bent by the pressing force of the bearings 13, 13, and is wrapped onto one end of the metal fitting 1 which has been bent in advance. In this case, when the metal fitting 1 is bent, the hole 3 provided at the other end of the metal fitting 1 is preset so that the claw 2 passes through the hole 3. There is no risk that the area around the hole 3 (bearings 13, 13, etc.) will come into contact with the claw 2 as it is passed through. Therefore, even after the first pressing part 13 completes wrapping the other end of the metal fitting 1 to one end and the first pressing part 13 passes, only the claw 2 remains protruding in the vertical direction. Needless to say. Moreover, in this case, the first
In order to prevent the rubber holder 4 and the like from moving due to the pressing force of the pressing part 13, it is desirable that the depth of the recessed receiving part of the pedestal is slightly deeper than the center of the pipes 5, 5. Next, as the metal plate 11 moves further forward, as shown in FIG. It is then wrapped in a tightened state, and the tightening and fixing of the fixing fitting 1 is completed.

In this case, it goes without saying that when the bending of the metal fitting 1 is completed, the air cylinder 10 is immediately returned to its original position by a switching valve (not shown) or the like.

In this example, the device tightens the metal fitting 1 by linearly moving the metal plate 11, but if the outer periphery of the rubber protector 4 or the like has a curved surface, a device that tightens by a curved movement may be used. It is also possible to do this.

Further, in this example, the air cylinder 10 is used as a device for reciprocating movement in the pressing mechanism 7, but this is not particularly limited.

Also, although this example shows the case where the pipes 5 and 5 are integrated, it is also possible to integrate electric wires, etc.
Moreover, the number is not limited to only two.

As described above, according to this invention, the structure of the metal fastening device is such that both ends of the fastening metal having claws and holes at both ends are connected and integrated in one operation.
There is no need to connect manually as in the past, and there are no occupational health problems. Moreover, it has great practical value, as it has very good working efficiency and can be made smaller because it has a simplified structure.
