TECHNICAL FIELD The present invention relates to a deburring device for simultaneously deburring a plurality of burrs generated on an end surface of a round material such as a round bar and a round pipe.

[0002]

2. Description of the Related Art A round material such as a round bar or a round pipe has a burr on its end face during the manufacturing process, and it is necessary to remove the burr. Usually, the work for removing the burr is performed by grinding the end surface using, for example, a brush device described later. In this case, conventionally, a method of grinding a round material clamped one by one, or a method of using a spiral roll or a chain conveyor to grind a plurality of circular materials while moving them at regular intervals so as not to contact each other, etc. Was taking.

[0003]

However, there are the following problems in the above-mentioned conventional deburring work for round material. That is, the work efficiency is very low when deburring by clamping the round materials one by one. In addition, when the above spiral roll or the like is used, the equipment space and the equipment cost increase, which leads to an increase in product cost.

On the other hand, in order to improve the efficiency and reduce the cost, a method is conceivable in which a plurality of round materials are clamped at one time and a plurality of round materials are simultaneously deburred. For example, FIG.
As shown in FIG. 5, there is a method in which five round members 8 are clamped at once and deburred by a brush device 9. However, in this case, as shown in FIG. 8 and FIG. 9, deburring of the contact portions 88 of adjacent round members cannot be performed, and deburring may occur. This is because the wire brush 10 of the brush device 9 does not reach the corner portion on the longitudinal circumferential surface side of the round member 8 at the contact portion 88.

The present invention has been made in view of such conventional problems, and provides a round material deburring apparatus capable of obtaining a high-quality round material having high efficiency, low cost, and no burr residue. It is the one to be provided.

The round material 8 delivered to the third aligning roll 53 is sent to the next step by the rotation of the third aligning roll 53. By sequentially performing such a series of operations on the sequentially supplied round members 8, it is possible to continuously deburr a large number of round members 8.

As described above, in this example, when deburring a round material, a plurality of round materials 8 whose end faces are aligned are clamped at once by the clamp rolling device 3 and deburring is performed simultaneously. Therefore, it is possible to work with extremely high efficiency. The deburring work is performed while the clamp rolling device 3 rolls the round material 8 continuously or intermittently.
Therefore, it is possible to prevent the occurrence of a local burr residue at the contact portion 88 of the adjacent round members 8. Therefore, the end surface of the round material 8 has an excellent quality with no burr residue.

Further, in this example, the first deburring device 101 and the second deburring device 102 are provided on both left and right sides of the round material 8 in the traveling direction. Therefore, both ends of the round material 8 can be continuously deburred, and the working efficiency can be further improved.

In this example, the round material 8 was rolled while the burr was removed by the brush device 4. However, after the round material 8 was firmly held and deburred once, the round material 8 was rotated a little. It is also possible to use a method of moving and then deburring again. In this case also, the same effect as above can be obtained.
