Abstract

PURPOSE:To remove a burr from a hanger piece of a cable, which is formed during molding. CONSTITUTION:A deburring body having a substantially hollow columnar shape in assembly, and having a large diameter inlet hole guide 4 and a deburring part 42 following the former in the axial direction thereof, are formed in the hollow part thereof, is composed of a deburring body halves 4A, 4B which are bi-divided from each other by a plane containing the center axis. At least one of the inlet guide hole 4 is formed in the deburring body on the upstream side along the running line of a cable just after the molding of a hanger piece.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring device for a cable, particularly a pre-hanger cable.

[0002]

2. Description of the Related Art As shown in FIG. 1, a pre-hanger cable is a cable which has a low tensile strength, for example, an optical cable 1 which is preliminarily suspended by an appropriate suspension wire 2 having a high tensile strength. Thus, the hanger pieces 3 are provided between the suspension wire 2 and the suspended wire 1 at appropriate intervals in the longitudinal direction for suspension.

Such a hanger piece 3 is a suspension line 2
In order to measure the integration between the cable and the suspended wire 1, these wires are run in parallel, and a molding die is attached to both wires at appropriate intervals in the longitudinal direction to perform injection molding. FIG. 4 exemplifies a molding die 5 used for this purpose, in which two dies 5A and 5B symmetrical with respect to the mating surface 51 are provided.
Form a matching type. In the figure, 51 is a sprue, and 53A and 53B are cavities for the suspension wire 2 and the suspended overhead wire 1, respectively.

[0004]

As is well known, an injection-molded product has a molding burr at the sprue and a protruding burr at the mating surface.
It extends to a length of about 0 mm and adheres. Since the pre-hanger cable has a large number of hanger pieces formed by the injection molding method at appropriate intervals as described above, there is a disadvantage that the burrs extending up and down of these hanger pieces seriously impair the appearance.

[0005]

The present invention has been made in order to solve the above-mentioned problems, and the united shape is a substantially hollow cylindrical shape, and an introduction guide hole of a slightly large diameter is formed in the hollow portion. A deburring body having an axially following deburring portion is formed of a deburring half divided by one plane including the central axis line, and at least one deburring body is formed immediately after forming a hanger piece. Is a deburring device for the cable, which is arranged along the running line of the cable with the introduction guide hole on the upstream side.

[0006]

The cable passes through the deburring body while traveling, and the burrs protruding here are removed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a pre-hanger cable immediately after manufacturing with a deburring member 4 (in the illustrated example, deburring member 4) of the present invention.
2 are connected in series) from the right side to the left side in the drawing to remove the burr 31. Reference numeral 43 indicates a frame for installation.

As shown in FIGS. 2 and 3, the deburring member 4 has two deburring halves 4A and 4B, each of which is a substantially hollow columnar member and is divided into two parts by a plane including the central axis. The deburring device can be set in the manufacturing line following the manufacturing process of the pre-hanger cable, as a matter of course because it is formed by combining the halves. .

As can be seen from the side view of FIG. 3, the individual burr-removing halves 4A and 4B are compared with the outer dimension L above and below the hanger piece 3 shown in FIG. 1 at the portion corresponding to the inlet of the pre-hanger cable. An introduction guide hole 41 having a relatively large diameter is formed, and a deburring portion 42 is subsequently formed from the introduction guide hole 41 with a proper taper to reduce the diameter.

The inner diameter of the deburring portion 42 is the above-mentioned outer dimension L.
Is adjusted according to. The burr 31 of each hanger piece 3 is scraped off at the burr-removing portion 42 of the pre-hanger cable immediately after manufacturing by passing through the burr-removing body 4.

[0011]

According to the present invention, a cable, particularly a pre-hanger cable, generally passes through a burr removing body while traveling, and the burrs above and below the hanger piece are effectively removed, so that a cable with a good appearance can be obtained. There is an effect that can be manufactured.
