Abstract

PURPOSE:To easily remove a cast burr and a throwaway crosspiece at a specific speed without imparting a shock onto an insulating cap metal fitting by cutting and removing the throwaway crosspiece by the use of a cutting blade in removing the cast burr of the insulating cap metal fitting by the use of the cutting blade. CONSTITUTION:A cutting blade 10 of a copy cutting machine is rotated at a predetermined speed, to be moved on a locus (b) along a profile. In order to remove a throwaway crosspiece 5 by the use of the cutting blade 10, an insulating cap metal fitting 1 is first fixed to a workpiece presser of the copy cutting machine, and the cutting blade 10 is rotatably driven to be moved along the locus (b). Since the locus (b) is formed in such a manner as that the outer peripheral surface of the cutting blade 10 is moved along the profile of a clevis portion 3, the cutting blade 10 is moved so that a burr 6 can be removed and the throwaway crosspiece 5 can be removed at the same time. Consequently, it is possible to easily remove the burr 6 and the crosspiece 5 without imparting a shock onto the insulating cap metal fitting 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing a throwing rod of an insulator cap member.

[0002]

2. Description of the Related Art An insulator cap metal fitting (hereinafter referred to as an insulator metal fitting) 1 shown in FIGS. 2 and 3 is a cast insulator metal fitting, and FIG.
Is a left side view thereof.

The insulator fitting 1 is a cap portion 2 in the form of a fishing wire.
And a clevis portion 3 formed by a pair of projecting pieces 3a and 3b integrally provided on the upper portion of the cap portion 2 with a predetermined gap. A through hole 4 is provided in the pair of projecting pieces 3a and 3b.

When the insulator metal fitting 1 having the above-described structure is cast, when the molten metal is solidified and solidified, the clevis portion 3 is deformed, and the distance between the pair of projecting pieces 3a and 3b cannot be kept as predetermined. Therefore, in order to prevent this, the upper end portions of the pair of projecting pieces 3a and 3b are joined by the discarding box 5 and cast.

When the insulator metal fitting 1 is finished, the throwing iron 5 is cut by a hammer with an impact. In the figure, reference numeral 6 denotes a flash (hereinafter referred to as a burr), which is cut and removed by a blade when finishing the insulator fitting 1.

[0006]

However, the above-mentioned conventional method for removing the waste cauldron of the insulator metal fittings is not preferable because the insulator metal fittings are urged because they are removed with a hammer. There is a problem that the workability is inferior because it has two steps of removing the discarded waste.

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and its purpose is to easily remove the throwing cauldron without giving an impact to the insulator caulking metal. To provide a method.

[0008]

In order to achieve the above-mentioned object, the method of the present invention is a method for removing a waste cauldron of an insulator cap metal fitting for removing the cauldron from an insulator metal fitting that is cast with a waste cauldron, When the burr of the insulator metal fitting is removed by using a blade, the waste cauldron is cut by the blade and removed.

[0009]

In the above construction, when the burr of the throwing scraper metal fitting is cut by the blade, it is cut and removed by the blade.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the removal of the waste cauldron according to the method of one embodiment, and the same reference numerals are used for the same components as those in FIGS. Only the different reference numerals will be given and described.

Reference numeral 10 is a well-known profile cutting machine (not shown).
It is a cutting blade of and rotates at a predetermined rotation speed,
It is configured to be able to move along the outer shape of the clevis portion 3 (see locus a in FIG. 1).

In order to remove the throwing rod 10 with the cutting blade 10, first, the insulator fitting 1 is fixed to the work holder of the tracing cutting machine, and the cutting blade 10 is rotationally driven. Then, the cutting blade 10 is moved along the trajectory a. Trajectory a is cutting blade 1
Since the outer peripheral surface of 0 is determined to move exactly along the outer shape of the clevis portion 3, the burr 6 is removed by the movement of the cutting blade 10, and the discarding sleeve 5 is also removed at the same time.

As described above, according to the method of the present embodiment, the burr 6 and the waste casket 5 can be removed together by the cutting blade 10 by cutting, so that the insulator metal fitting 1 can be easily removed without impulsive force. effective.

[0014]

According to the method of the present invention, when the burrs of the insulator metal fittings are removed by using the blade, the waste cauldron is cut by the blade to remove the burrs. It can be removed quickly and easily.
