BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing both sides of a processing burr, which can smoothly transfer a work from a work transfer means to a polishing apparatus and can prevent the work surface from being damaged.

[0002]

2. Description of the Related Art When a workpiece such as a steel plate is cut by gas or plasma, slag (burrs) or hot spots are generated, and burrs are generated even in a shearing or punching press. For this reason, it is necessary to remove the processing burr accompanying these fusing or pressing.

The present invention is directed to an apparatus for removing both sides of a processing burr, and its basic structure is, as shown in FIG. 4, a work transfer means (1) facing a horizontal work transfer surface (4), and a belt type. The upper surface polishing device (2), the lower surface polishing device (3), and the work holding transfer means (11) are arranged, and the upper surface polishing device (2) is arranged opposite to the work transfer means (1) from above, and the lower surface polishing is performed. Equipment (3)
Is arranged on the work transfer surface (4) from the lower side in the transfer direction of the work transfer means (1), and the work holding transfer means (11)
Is placed facing the lower surface polishing device (3) from above, and the upper surface polishing device
(2) Belt sander (5) for bottom polishing device (3)
(6) is configured to be able to travel in parallel with the work transfer surface (4) and along the work transfer direction.

As a prior art of this type, as shown in FIG. 4, a work transfer means (1) is a transfer belt conveyor, and a transfer belt conveyor (1) and a lower surface polishing device (3) are moved in a transfer direction. Some are arranged in series from the upper side to the lower side. In the prior art, a work (W) conveyed by a conveyor belt conveyor (1) is first polished on its upper surface (14) by a belt sander (5) of an upper surface polishing device (2) and then on a lower surface polishing device. The lower surface (15) is polished in (3).

[0005]

In the above prior art, a gap (50) is provided between the conveyor belt conveyor (1) and the lower surface polishing device (3) because it is necessary to avoid interference between belts. I have. For this reason, the work (W) is caught in the gap (50) and is not smoothly transported to the lower surface polishing device (3), or the lower surface polishing device is displaced with respect to the transport direction.
There is a risk that the correction operation may require human labor or may not be able to be polished smoothly due to being carried into (3). Also work
When (W) is small, the above-mentioned adverse effects become large, or the conveyance itself becomes impossible. It is a technical object of the present invention to quickly transfer a work from a work transfer unit to a lower surface polishing apparatus.

[0006]

Means for achieving the above object will be described below with reference to FIGS. 1 to 3 showing an embodiment. That is, in the present invention, in the apparatus for removing both surfaces of the processing burr having the basic structure, a bridging member (7) for transferring a work is provided between a work transfer means (1) and a belt type lower surface polishing device (3). ) Is interposed from below, and the upper surface (8) of the bridging member (7) for work transfer is set along the work transfer surface (4).
A surface hardened layer (10) is formed on the work transfer upper surface (8) of (7), and the work transfer upper surface (8) is configured to have a convex surface protruding upward in a vertical cross-sectional view in the transport direction. .

Here, the convex surface of the workpiece transfer upper surface (8) is a concept including a convex curved surface and a convex smooth surface having a triangular apex angle. Surface hardened layer on the upper surface (8) for work transfer
(10) may be formed by quenching the surface of the cross-linking member (7), carburizing, or coating with a fluororesin.

[0008]

[Function] Work transfer means (1) and belt type lower surface polishing device
Since the work-passing bridging member (7) spans between (3),
The workpiece (W) is smoothly transported from the workpiece transport means (1) via the bridging member (7) without being caught by the lower surface polishing device (3).
(8) is a convex surface projecting upward, so that the frictional resistance during transport is small.

After the work is removed of burrs on the upper surface by the upper surface friction device (2), a bridging member is provided by the work transfer means (1).
The burrs are transported to the lower surface polishing device (3) via (7). At this time, the removed burrs are transported toward the bridging member (7) by the workpiece transporting means (1). Usually, the processing burrs generated by fusing have higher hardness than the work due to oxidation,
When the work is transferred to the lower surface polishing device (3) beyond the bridging member (7), the lower surface may be damaged by burrs accumulated in the bridging member (7). Is dropped while being guided downward on both sides by the convex surface of the work transfer upper surface (8), so that the lower surface of the work can be prevented from being damaged by rubbing of burrs. In addition, since a hardened surface layer (10) is formed on the upper surface (8) of the cross-linking member (7), the work,
Alternatively, the bridging member (7) can be well endured for long-term use with little wear due to processing burrs removed from the work.

[0010]

[Effects of the Invention] (1) Since the bridging member for transferring the work is bridged between the work transfer means and the lower surface polishing device, the work is caught in the gap between the work transfer device and the lower surface polishing device, and the work transfer means is provided. There is no possibility that the workpiece is not smoothly transported to the lower surface polishing apparatus side, and the posture of the work is not shifted. Therefore, the work caught in the gap between the work transfer means and the lower surface polishing device can be manually sent to the lower surface polishing device side, or the operation of correcting the position of the work to an appropriate position manually can be omitted. Removal of burrs from both surfaces of the work can be performed quickly and easily. (2) Even if the work is small, it can be smoothly bridged to the lower surface polishing device side without falling from the gap between the work transfer means and the lower surface polishing device by the interposition of the bridge member for transferring the work. Regardless of the size, the work can be reliably transferred from the work transfer means to the lower surface polishing apparatus side. In other words, large and small types of workpieces that can remove burrs will increase,
The utilization efficiency of the device is improved. (3) Since the work transfer upper surface of the work transfer bridging member is formed as a convex surface, the work transfer upper surface is not only inclined downward to the lower surface polishing device side but also inclined downward to the work transfer means side. State. In other words, the burrs removed from the workpiece by the upper surface polishing device are transported toward the bridging member by the workpiece transporting means, but the burrs removed from the workpiece are placed on the workpiece transport upper surface by the inclination of the workpiece transport upper surface. Without being accumulated, it is guided down the sides and dropped. Therefore, it is possible to prevent the burrs removed from the work from entering the lower side of the work when the work passes through the bridging member, thereby preventing the lower surface of the work from being damaged or worn by the burrs. Moreover, the burrs removed from the work due to the downward inclination of the work transfer upper surface toward the work transfer means are prevented from moving over the bridging member to the lower surface polishing apparatus side, and the burrs removed from the work are suppressed. Is sent to the lower surface polishing device side and sneaks between the lower surface of the work and the lower surface polishing device to prevent the lower surface of the work from being damaged or worn. Thereby, it is possible to reliably prevent the lower surface of the work from being damaged or worn by the burr removed from the work. (4) Since the surface hardened layer is formed on the work transfer upper surface of the work transfer bridge member, the strength of the work transfer upper surface is increased, and the work transfer upper surface is worn due to the work sliding on the work transfer upper surface. Can be reduced, and the life of the bridge member can be prolonged.
