A plate processing machine having a workpiece clamp for clamping, two auxiliary clamps provided on both side edges of the carriage side edge of the workpiece to removably clamp the workpiece, and a plurality of free bears on the lower surface. An auxiliary workpiece clamping device for a plate material processing machine, comprising a clamp fixing member and a slide table whose upper surface is formed into a flat plate shape and allows the workpiece to be moved freely via a free bearing of the clamp fixing member. .

[0007]

[Function] By adopting the auxiliary work clamping device for a plate material processing machine of the present invention, two clamp fixing members, which are provided with an auxiliary clamp that removably clamps the workpiece and a plurality of free bears on the lower surface, are attached to the carriage side of the workpiece. A slide table is provided on both sides of the edge, the upper surface is formed into a flat plate shape, and the workpiece is movable via the freebearer of the clamp fixing member, whereby a freebearer is provided on the workpiece side and the workpiece can be moved. The workpiece is floated on a slide table so that the workpiece does not get caught on the freebearer during axis movement, the back side of the workpiece is prevented from being damaged by the freebearer, and the beauty of the workpiece is maintained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a schematic diagram of the auxiliary work clamping device of the present invention. In the figure, a work clamp device 1 installed in a plate processing machine, for example, a punch press, has a length approximately equal to the full width of the punch press, and has a carriage base that moves the processing section of the corbel press a predetermined distance (moves in the Y-axis direction). 3, and a carriage 5 that is movably mounted (in the X-axis direction) by a worm shaft 33 built into the carriage base 3, and a carriage 5 that is wide or narrow so as to allow stable clamping movement according to the dimensions of the workpiece W. The clamp position can be adjusted each time, and the workpiece clamp 7 is attached to the carriage 5.

Both ends of the carriage base 3 are placed on a side table 9, and the workpiece W positioned in the X-axis direction is transported along with the carriage 5 a predetermined distance (in the Y-axis direction) to the processing section of the punch press. A predetermined process is performed using the machine.

The auxiliary workpiece clamping device 11 of the present invention includes two sets of clamp fixing members 13 and 13A used together with the workpiece clamping device 1, and a side table 9 which is a sliding table formed into a smooth flat plate. and a center table 15 (FIGS. 4 and 5).

The clamp fixing member 13 is a fixed type provided on the front side of the punch press and having one end fixed to the carriage 5. Further, as shown in FIG. 2, the clamp fixing member 13A is movable in the X-axis direction by a guide rail 35 provided on the back side and having one end provided in the carriage 5, and is positioned by a fixing claw 37 and a fixing screw 39. It is mobile.

As shown in FIG. 3, a plurality of free bears 17 are rotatably provided on the lower surfaces of the clamp fixing members 13 and 13A, respectively, and a clamping means for clamping both side edges of the workpiece W is provided. In the embodiment, an auxiliary work clamp 19 is provided which clamps the work W and is operated by a thin clamp cylinder 21 built into the clamp fixing members 13 and 13A.

[0014] Side table 9 and center table 15
does not have the conventional freebear, and the freebear 17 provided on the lower surface of the clamp fixing member 13, 13A is
The work W clamped by the auxiliary work clamp 19 is floated from the side table 9 and the center table 15, and the upper surfaces of the side table 9 and the center table 15 are made movable when the work clamp device 1 moves axially. Therefore, when the conventional workpiece W moves, it is prevented from being caught on the free bearer 17 and from being damaged thereby.

Next, FIG. 4 shows a state diagram of the auxiliary workpiece clamping device of the present invention during workpiece processing using a punch press. A die punch 27 is attached to the upper turret disk 23, and a die punch 27 is attached to the lower turret disk 25.
A mold die 29 is mounted opposite to. As the workpiece clamping device 1 moves in the Y-axis direction, the workpiece W passes through the center table 15 and moves to processing positions within the upper and lower turret disks 23 and 25, which are the processing sections of the punch press.

During processing, the mold die 29 is raised by a die up/down mechanism 31 such as a cylinder, wedge, etc., and comes into contact with the lower surface of the workpiece W, and the mold punch 27 is lowered by a ram (not shown) to perform punch processing. It will be done. Therefore, the workpiece W is lifted up from the center table 15 and the lower turret disk 25 by the free bear 17, and is maintained at a constant distance in a stable state.

Next, FIG. 5 shows a state diagram of the auxiliary workpiece clamping device of the present invention when the punch press is moving the workpiece. After processing, the workpiece W moves backward from the upper and lower turret disks 21 and 23, which are the processing parts of the punch press, but at this time, the workpiece W is lifted off the center table 15 and the lower turret disk 25 by the free bear 17 of the clamp fixing member 13. is held in a stable state and moved. Therefore, damage to the workpiece W due to free bears during movement is prevented, and the beauty of the workpiece W is maintained.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments by making appropriate design changes.

[Effect of the invention] As already clear from the above explanation,
The auxiliary workpiece clamping device for a plate material processing machine of the present invention includes two clamp fixing members each having an auxiliary clamp that removably clamps the workpiece and a plurality of free bears on the lower surface thereof, on both sides of the carriage side edge of the workpiece. The problems of the prior art are effectively solved by providing a slide table, which is formed into a flat plate shape with a smooth upper surface and allows the workpiece to be moved via the free bear of the clamp fixing member, and the free bear moves. Without getting caught on the workpiece, the back side of the workpiece is prevented from being damaged by free bears, and the beauty of the workpiece is maintained.
