Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an end face deburring device suitable for use in removing burrs from the end face of a bar material caused by cutting or the like.

[0002]

2. Description of the Related Art Conventionally, a coated arc welding rod has been used when arc-welding plate bodies such as Co-base alloy, Fe-base alloy, and Ni-base alloy. This coated arc welding rod has aluminum oxide (Al ₂ O ₃ ) outside the core wire (rod) made of a Co-based alloy, a Fe-based alloy, a Ni-based alloy, or the like.
It is a film-shaped flux mainly composed of
The core diameter is 1.4 to 8 mm and its length is 1.4
200 mm for mm, 900 m for 8 mm
m and so on. In this coated arc welding rod, a core material made of a Co-based alloy, a Fe-based alloy, a Ni-based alloy or the like is cut into a core wire by a high-speed cutting machine or the like to form a core wire, and the core wire is dipped in a flux. Is manufactured by applying flux processing to the outside of the core wire.

As shown in FIG. 3, burrs 2 are formed on the core wire around the end face 1a of the core wire 1 at a considerably large rate during cutting. The burr 2 is particularly prominent in a difficult-to-work material such as a Co-based alloy or a Ni-based alloy, and the burr 2 becomes an obstacle during flux processing. Therefore, after cutting, perform 100% visual inspection on all the core wires 1,
Select the core wire 1 in which the burr 2 has occurred, and set this core wire 1 to 1
The burr 2 is removed by hand-polishing one by one.

[0004]

In the conventional hand polishing method, it is necessary to perform a total visual inspection on all the core wires 1, so that a lot of manpower and time are required for this inspection process, and However, there is a problem that the burr 2 is always overlooked because it is visually inspected. In addition, the core wire 1 is 1
Since the polishing is done by hand one by one, a lot of manpower and time are spent in this polishing process, which is one of the factors that cannot reduce the cost. For example, in the case of a 3.2 mm Ni-based alloy welding rod, it takes about 1 minute to process one rod.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an end face deburring device for a rod material, which is capable of removing burrs from the end surface of the rod material very easily and in a short time.

[0006]

In order to solve the above problems, the present invention employs the following deburring device for the end face of a bar. That is, a tubular portion that inserts and supports the rod member, a driving portion that supports the tubular portion with its axis inclined with respect to the vertical axis, and that rotates the tubular portion around the vertical axis,
And a grinding portion having a grinding surface which is arranged close to the lower end of the cylindrical portion and is movable in one direction on a horizontal plane.

[0007]

In the device for deburring an end surface of a rod according to the present invention, the rod is inserted into the tubular part along the inner peripheral surface of the tubular part with the end face of the bar having the burr facing downward. By driving the driving unit, the tubular unit is rotated about the vertical axis in a state where the tubular unit is supported with its axis inclined with respect to the vertical axis. At this time, since the end surface having burrs is in contact with the abrasive surface that moves in one direction in the horizontal plane, the end surface is cut and polished by the abrasive surface for a predetermined length, and therefore the burrs on the end surface are also removed at the same time. To be done. As a result, it becomes possible to remove the burr on the end surface of the bar extremely easily and in a short time.
