Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat treatment device for a heat-shrinkable tube-fitted brake hose.

[0002]

[Prior art]

 Generally, brake hoses are commercially available with joint fittings fastened to both ends.

On the other hand, in recent automobiles, the engine room and the tire house have become smaller and narrower as the front engine and the front drive have been made. The brake hoses installed in these engine rooms and tire houses are at increased risk of coming into contact with other equipment.Therefore, contact the brake hoses so that they will not be damaged if they come into contact with other equipment. A hose protector is fitted on the outer periphery of the parts that are easily damaged by. Further, as shown in FIG. 5, the brake hose is fixed to the frame bracket 13 by the joint fittings 10 and 11 at both ends and the wheel side joint 14 on the other side. Since it will sway due to abnormal deformation or contact with other equipment and it will be easily damaged, fit a hose protector 9 on the outer circumference of the brake hose at the contact danger point, and if necessary, attach the hose protector 9 to the column 15 via the hose protector 9. The hose 8 is also fixed.

Conventionally, the work of fitting a hose protector to a brake hose is performed by fitting a hose protector 9 made of a heat-shrinkable tube to the brake hose 8 as shown in FIG. (Not shown), and then put it in a heat treatment device such as a thermostat to heat-treat and fix the heat-shrinkable hose protector 9 at a predetermined position (determined by the mold) on the outer circumference of the brake hose 8. After that, joint fittings were fastened to both ends of the brake hose 8 to obtain a finished product as shown in FIG.

In addition to the fitting work using the heat-shrinkable hose protector described above, the fitting work using the cold-shrinkable hose protector as proposed in Japanese Patent Publication No. 63-8351, or the actual fitting work. Although a method has been proposed in which an adhesive agent is introduced into the hose protector as proposed in JP-B-55-24461 to fix the adhesive, such a special hose protector is difficult to obtain and is not general. .

In the fitting work using the conventional heat-shrinkable hose protector described with reference to FIGS. 3 and 4, the work steps include the hose protector fitting work, mold mounting work, and heat treatment work. In addition, since the brake hose is commercially available with joint fittings fastened to both ends, it is necessary to remove the joint metal fittings before the work and reattach it after the fitting work. The process is becoming longer and more complicated, the productivity is extremely low, the hose is likely to be damaged during the work, and the parts other than the protector are heat-treated.

[0007]

[Problems to be solved by the device]

 The object of the present invention is to solve the above-mentioned drawbacks of the prior art, to manufacture a high-quality heat-shrinkable tube-fitted hose that is less likely to cause damage or heat deterioration to the hose, and has excellent productivity. To provide a heat treatment apparatus.

[0008]

[Means for Solving the Problems]

 The above problems can be achieved by the heat treatment apparatus for a heat-shrinkable tube covered hose of the present invention.

The structure of the heat treatment apparatus of the present invention will be described with reference to FIGS. 1 and 2. 2 is a cross-sectional view taken along the line AA of FIG.

That is, in FIG. 1 and FIG. 2, a drive shaft 2 driven by a drive device 1, a drive shaft 2 fixed at a desired interval, rotated together with the drive shaft 2, and on the outer circumference, for example, And a plurality of hose receiving bodies 4 having a plurality of heat shrink tube grooves 3 opened in the direction of the drive shaft 2 for receiving the hose 8 as shown in FIG. A heat treatment device for a heat-shrinkable tube-fitted hose, comprising a hot air blowing device 5 installed above a hose receiving body 4 of the main body device.

The position and the number of the hose receiving bodies 4 of the main body device can be arbitrarily changed depending on the installation position and the number of the heat shrinkable tubes 9 provided on the hose 8.

The operation of the heat treatment apparatus of the present invention is that the position and number of the hose receiving bodies 4 of the main body apparatus are set to be predetermined, and the heat shrinkable tubes 9 are passed through the hose receiving bodies 4 in advance at both ends. The hoses 8 with the fittings tightened are sequentially loaded so that the heat-shrinkable tubes 9 fit in the heat-shrinkable tube grooves 3 (maximum 12), and the hose receiving body 4 is driven by the drive unit 1 via the drive shaft 2. By heat-treating with the hot-air blowing device 5 while rotating, the heat-shrinkable tube 9 can be fixed to the hose very efficiently.

In the heat treatment apparatus of the present invention, the hot air blowing device 5 is installed above the hose receiving body 4 of the main body device. It is desirable that the surface of the device 5 facing the hose receiving body 4, that is, the surface on which the outlet 7 is provided, has an arc shape similar to the arc of the wheel-shaped hose receiving body 4, and the length of the arc is long. The length is not particularly limited as long as it is a length that can sufficiently heat-shrink the heat-shrinkable tube 9.

The number of hose receiving bodies 4 of the device 5 may be greater than or equal to the designed number of heat-shrinkable tubes 9 to be provided in the hose 8. Also, it is not necessary to have fittings at both ends of the hose 8.

Further, the heat treatment apparatus of the present invention can be used not only for the work of fitting the heat-shrinkable hose protector to the brake hose but also to the general work of fitting the heat-shrinkable protector to the hose. .

[0016]

[Effect of device]

 The heat treatment apparatus for a heat-shrinkable tube-fitted hose of the present invention makes it possible to manufacture a heat-shrinkable tube-fitted hose of higher quality than ever before with extremely high production efficiency, without damaging the hose or causing heat deterioration.
