DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus for removing burrs generated when a metal sheet such as a steel plate is cut to form a metal sheet material.

[0002]

2. Description of the Related Art When a metal sheet such as a steel plate is cut into a required width to form a metal sheet material, when the metal sheet material is cut by a cutting machine such as a shearing machine, as shown in FIG. Burrs 2 are generated in the opposite direction to the other side end. Since the burr 2 has a poor appearance and is sharp, it must be handled with care. Therefore, deburring is performed in consideration of appearance and handling.

A conventional deburring device has two upper and lower rollers 3, 4 as shown in FIG. 8, and the deburring is to pass the sheet material 1 between the rollers 3, 4. The one roller 3 is a buff roller, and the burr 2 protruding upward by the buff roller 3 is polished and removed.

[0004]

However, as described above, the burrs 2 are formed so as to protrude in two directions, but only the burrs 2 which protrude upward can be deleted by the above-described deburring apparatus. Therefore, in order to completely remove burrs, the sheet material 1 is turned upside down after one side is polished, and the burrs on both the upper and lower surfaces are removed by allowing the sheet material 1 to pass again between the rollers 3 and 4. For this reason, there was a problem that the number of steps was large and the efficiency was poor. Further, since the burrs 2 are removed by polishing, the surface of the sheet material 1 is also scratched by the polishing, and there is a problem that the product value of the sheet material itself is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a deburring apparatus which can remove burrs on both edges at the same time and does not damage the surface of a sheet material.

[0006]

According to the present invention, there is provided a fixed vertical roller provided with a groove for deburring, and a movable vertical roller capable of moving toward and away from the fixed roller. The present invention relates to a deburring apparatus configured to move a sheet material in a state where it is fitted in the grooves of both vertical rollers and to perform deburring on both end edges of the sheet material, and also has a fixing in which a groove for deburring is formed. A deburring machine including a vertical roller, a movable vertical roller capable of moving toward and away from the fixed roller, a cylinder for moving the movable vertical roller toward and away from the fixed roller, and upstream and downstream of the deburring machine. And a conveying device having a horizontal roller capable of holding and rotating the sheet material from above and below, and a rotatable roller.
Deburring of both ends of the sheet material is performed at one time, and only the edges are reduced, so that the surface of the sheet material is not damaged.
