Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deburring device for removing burrs generated on a plate material due to press working, etc.
More specifically, the present invention relates to an apparatus that can easily deburr holes punched into a workpiece (plate material) regardless of their shape or direction.

Conventional deburring equipment uses belt sanders, brushes, bubs, etc. that deburr plates transported by a roller conveyor or belt conveyor, and simply rotates on a horizontal axis of rotation perpendicular to the direction in which the plates are transported. only. Therefore, for example, when punching a rectangular hole in a plate material, if the edge of the hole is perpendicular to the direction in which the plate material is transported, the generated burrs can be removed relatively reliably. However, if the edge of the hole is parallel to the direction in which the plate is transported, the removal of burrs is insufficient, and it is often necessary to subject the plate to the deburring device again.

In addition, in conventional deburring equipment, the conveyor is generally installed at a certain height, so when trying to incorporate it into a processing line,
There are problems such as that it is extremely difficult to match the heights of the conveyor in the processing line and the conveyor in the deburring device.

The present invention was invented in view of the conventional problems as described above, and its purpose is to eliminate burrs formed on the edge of the hole, regardless of the shape and direction of the hole machined in the plate material.
It is an object of the present invention to provide a deburring device that can reliably remove burrs in one pass and that can easily accommodate conveyors of various heights in the processing line when installed in the processing line.

Hereinafter, a preferred embodiment of the present invention will be described in detail using the drawings.

and the axis 143 of the pin 143 of the second link 141
The distance l ₂ between the axes between P and the pin 145P is the same distance (l ₁ =l ₂ ), forming a so-called parallel link mechanism.

Pinch roller 129 of the material pressing device 17
The force to press down the plate material from above is exerted by the weight of the material holding device 17, and the pinch rollers 129 on both left and right sides of the deburring wheel 7 are always in contact with the belt conveyor 15. . The vertical movement of the material holding device 17 follows the vertical movement of the belt conveyor 15, and the pinch rollers 129 on both the left and right sides of the deburring wheel 7 are moved in synchronization and parallel to the deburring wheel 7. Move up and down.

A bracket 147 for fixing the table 13 is provided on the rear side of the frame 3, and a bolt 149 is inserted through the bolt hole of the bracket 147.
The table 13 is fixed by being screwed into the screw hole 151 of the table 13.

In the above configuration, when the plate material to be deburred is fed onto the belt conveyor 15 on the table 13 after driving each rotating part, the plate material is pressed by the pinch roller 129 of the material pressing device 17 and is being transferred. Deburring is performed by the deburring wheel 7, which rotates at high speed while moving in the front-rear direction.

Further, the deburring wheel 7 is supported at both ends by flanges 23 attached to both ends of the wheel shaft 21, and is supported near the center by a collection chuck 27, so that the deburring wheel 7 is not deflected. Therefore, deburring can be performed uniformly at any position over the entire width of the deburring wheel 7.

The deburring wheel 7 also has a clevis 65 that moves vertically and longitudinally by the rotation of an eccentric shaft 67 via a rod 61 connected to a multistage pulley 41 fixed to the other end of the wheel shaft 21. Since the deburring wheel 7 rotates at high speed while moving back and forth, it is possible to completely remove burrs from all directions on the plate material.

Further, the material holding device 17 has pinch rollers 12 mounted on the lower ends of both left and right sides of a gate-shaped arm 123 that is vertically movably supported by a parallel link mechanism consisting of a first link 133 and a second link 141.
9 are arranged symmetrically and rotatably supported, and the force for pressing the plate material from above by the pinch rollers 129 is automatically performed by the material pressing device 17. The vertical movement of the belt conveyor 15 follows the rise and fall of the belt conveyor 15, and the pinch rollers 129 on both the left and right sides of the deburring wheel 7 move up and down synchronously and parallel to the deburring wheel 7. Even when a narrow plate is fed, the pinch roller 12
9 will not hit unevenly, and therefore the meandering of the plate material can be prevented.

Furthermore, in the above embodiment, when replacing the belt conveyor 15 of the table 13, the table 13 is fixed to the bracket 147 with bolts 149, and then the front adjustment screw 91 is fixed to the table 13. Bolt 95
The belt conveyor 15 can be replaced by removing the spacer 93 and replacing the belt conveyor 15 through the gap left after the spacer 93 is removed.

As can be understood from the above description of the embodiments, the gist of the present invention is as described in the claims.As is clear from the description, the present invention provides a plurality of The rotating bodies rotatably provided at different locations are interlocked with each other, and the table is supported horizontally by adjusting screws screwed onto the rotating bodies so as to be able to move up and down. A worm wheel is attached to a suitable rotating body, and a worm is meshed with the worm wheel.

Therefore, according to the present invention, the table can be moved up and down by rotating the worm. That is, when the deburring device is incorporated into a processing line, it can be easily incorporated in response to changes in the height of the conveyor in the processing line. At this time, since the wheel shaft itself is provided to be able to move up and down, there is no need to move the wheel shaft up and down again in response to the up and down movement of the table.

Further, according to the present invention, since the adjustment screw screwed onto the rotary body is moved up and down as described above, the rotary body is not rotated by pressing the deburring wheel or by the weight of the table. Furthermore, since the rotation of the rotating body is achieved by the engagement of the worm and the worm wheel, there is no possibility of rotating the worm from the rotating body side, so there is no need to use any kind of locking device. The table can be adjusted and fixed at a desired height without having to use the table.

Furthermore, in the present invention, the wheel shaft that supports the deburring wheel is provided to extend in the front-rear direction with respect to the plate material that is moved in the left-right direction by the conveyor; It can be moved. Therefore, according to the present invention, even if a rectangular hole is machined in a plate material and burrs are generated on the periphery of the hole, the burrs generated on the long edges of the rectangular hole in the front and back direction are not burred. Removes more of the rotation of the wheel, and also
The burrs formed on the long edges of the rectangular hole in the left-right direction are removed by moving the deburring wheel back and forth. Furthermore, even if the edge of the hole is in a direction that intersects the front-rear direction and the left-right direction, burrs formed on the edge are removed by rotating and moving the deburring wheel back and forth. In other words, burrs can be reliably removed regardless of the directionality of the edge of the hole machined in the plate material.

Note that this invention is not limited to the above-mentioned embodiments, and the invention can be implemented in modes other than the above-mentioned embodiments.
