Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an apparatus for processing an aluminum cover, which is used when connecting a cable to the aluminum cover.

[Prior Art] When connecting an aluminum cable, the cable aluminum tube and the connecting part aluminum tube are processed as follows.

(1) Cutting the aluminum sheath 14 at the end of the aluminum sheathed cable 10 (Fig. 4a).

For this, the cutting roller 20 is used.

In addition, 12 is a cable core.

(2) After connecting the cable core 12, corrugating the aluminum pipe 16 at the connecting portion (Fig. 4b).

For this, the corrugating roller 30 is used.

(3) Do not corrugate the end 18 of the connecting part aluminum tube 16,
Leave it flat and remove the excess (4c
Figure).

At this time, the cutting roller 20 is used.

(4) The end 18 of the aluminum pipe 16 at the connecting portion is squeezed so as to be in close contact with the end of the cable aluminum sheath 14 (Fig. 4d).

At this time, the squeezing roller 40 is used.

Among these, the following is known as a device for performing the corrugation of (2) (see Japanese Utility Model Laid-Open No. 57-141821).

In FIG. 5 and FIG. 6, reference numeral 50 denotes the entire frame, which is composed of two facing side plates 52 and three connecting plates 54 connecting them.
Each side plate 52 has a circular hole 56 for passing an aluminum pipe 55 (such as the connecting part aluminum pipe 16 described above).

In this frame 50, the following (1) pressing means 57 and (2)
A holder 63 for the corrugating roller 30 is provided.

For the sake of convenience in the description below, the direction of the central axis of the aluminum pipe 55 will be referred to as the z direction, and the radial direction of the aluminum pipe 55 will be referred to as the r direction.

(1) Regarding the holding means 57 of the aluminum tube 55: This is provided on the outside of each side plate 52 at three positions around the circular hole 56 at equal intervals.

Presser foot 58 and screw 60 (presser foot)
It is rotatable with respect to 58, but is attached in a state where movement in the r direction is restricted), and a nut 62 (fixed to the side plate 52) into which the screw 60 is inserted.

When the screw 60 is rotated, the presser foot 58 moves forward and backward in the r direction to clamp or open the aluminum pipe 55.

The corrugating roller 30 is provided at an intermediate position of the pressing means 57.

(2) Regarding the holder 63 of the corrugating roller 30: This is shown with a part omitted in FIG. 5, and the details of the structure are mainly shown in FIGS. 6 and 7.

The holder 63 is mainly attached to a screw 66 (which is rotatably fitted in a circular hole 64 provided in each connecting plate 54), a cylindrical body 68 screwed to the outside thereof, and a tip of the cylindrical body 68. Consists of clevis 70.

The corrugating roller 30 is attached to the clevis 70.

The corrugating roller 30 is displaced in the r direction by the rotation of the screw 66.

A vane 72 is integrally attached to the cylindrical body 68, and a part of the vane 72 is exposed on the surface of the connecting plate 54 through a hole 74 formed in the connecting plate 54.

Further, 76 is a nut and 78 is an adjusting screw.

By turning the adjusting screw 78, the cylindrical body 68 rotates around its central axis, and the angle of the corrugating roller 30 with respect to the aluminum tube 55 changes.

The above is the structure of the conventional corrugating device.

[Problems to be Solved by the Invention] However, the above corrugating device has only the corrugating roller 30, and when using the cutting roller 20 and the squeezing roller 40, it is necessary to use separate tools for each. , The tools had to be replaced at each stage, and the work efficiency was poor.

[Means for Solving the Problems] In the present invention, the known corrugating device for operating the corrugating roller 30 described above is improved to replace the corrugating roller 30 with the cutting roller 20 or the cutting roller 20. By replacing the squeezing roller 40 with the squeezing roller 40, the tool to be used has been improved to have a multi-function type, thereby eliminating the above problem.

To do that I did the following:

[Example] (1) For corrugation: As illustrated in Fig. 1a, a U-shaped notch 80 is provided at the tip of the clevis 70.

Further, a part of the shaft 32 of the corrugating roller 30 is cut to form the groove 34.

When attaching the corrugating roller 30, as shown in FIG. 1b, the shaft 32 is fitted into the notch 80, and then as shown in FIG. 1c.
Put a part of the stop plate 82 in the groove 34, and apply it to the clevis 70,
Secure with screws 84.

As a result, the corrugating roller 30 is attached.

When removing, reverse the above.

(2) Regarding the cutting roller 20 and the squeezing roller 40: As shown in FIG. 2, the shaft 22 of the cutting roller 20 has the same size as the shaft 32 of the corrugating roller 30 and is in the same position as the groove 34. A groove 24 of the same size is provided.

As for the squeezing roller 40, the shaft 42 has the same size as the shaft 32 of the corrugating roller 30 and the groove 44 of the same size is provided at the same position as the groove 34, as shown in FIG.

With this configuration, the cutting roller 20 and the squeezing roller 40 can be easily attached and detached.

Therefore, the cutting roller 20, the corrugating roller 30, and the squeezing roller 40 can be easily replaced.

(3) How to use the device With the frame 50 mounted on the cable sheath 14 and the connecting pipe 16, the cutting roller 20, the corrugating roller 30, and the squeezing roller 40 are attached.
The work shown in FIGS. 4a to 4d can be carried out only by replacing the above.

Although three corrugating rollers 30 are used for corrugation work, only one cutting roller 20 and one constriction roller 40 are used for cutting and drawing work, respectively.

At that time, only one cutting roller 20 and one squeezing roller 40 are replaced with the corrugating roller 30, and the remaining corrugating roller 30 is retracted.

[Advantage of the Invention] The clevis 70 provided at the tip of the holder 63 is provided with a U-shaped notch 80, and the shafts 22, 32, 42 of the cutting roller 20, the corrugating roller 30, and the squeezing roller 40 are provided. The same size, and the grooves 24, 34, at the same position of the shafts 22, 32, 42, respectively.
Any one of cutting roller 20 or corrugating roller 30 or squeezing roller 40 forming shaft 44 or shaft
The clevis 70 is inserted so that the shaft 32 or the shaft 42 is fitted into the notch 80, and the stopper plate 82 is fitted into the groove 24, the groove 34, or the groove 44.
Since it is attached to and detached from the frame,
The cutting roller 20, the corrugating roller 30, and the squeezing roller 40 can be exchanged while the 50 is attached to the cable sheath 14 or the connecting pipe 16, and the above 4a to 4d can be simply replaced.
The entire work shown in the figure can be performed.

Therefore, work efficiency is improved.
