BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate processing machine such as a punch press machine or a laser processing machine, and more particularly to a plate processing machine equipped with a work supporting member that moves integrally with the plate being processed.

0002

[Prior Art] Conventionally, when processing a plate material using a plate processing machine such as a turret punch press machine or a laser processing machine, a punching section consisting of a punch and a die,
A plate processing section such as a laser processing section consisting of a laser processing head is fixed, and a fixed table is provided in front of this plate processing section, and side tables that are movable in the Y-axis direction (back and forth) are installed on both sides of this fixed table. It is provided.

[0003] This side table is integrally provided with a carriage base extending in the X-axis direction (left and right direction) across the fixed table, and this carriage base has a clamp for clamping the plate material. X with equipment
A carriage is provided that is freely movable in the axial direction.

[0004] Then, by clamping the plate material to the clamping device and moving the carriage base in the Y-axis direction and the carriage in the X-axis direction, the desired position of the plate material is positioned in the plate processing section, It is common to process plate materials.

[0005]

[Problems to be Solved by the Invention] However, in the above-mentioned prior art, a plurality of rotatable free bearings are supported on the fixed table and the side table to support the plate material, and it is difficult to move the plate material in the X-axis and Y-axis directions. When moving, the plate material is supported by the plurality of rotatable free bearings to prevent damage to the back surface of the plate material, but in particular, the plate material suddenly moves on the fixed table in the Since the plate may be moved in different directions, scratches inevitably occur on the back side of the plate. Therefore, there is a problem in that the commercial value of the processed plate material is reduced.

[0006] Furthermore, the fixed table is provided with a tilting table for carrying out which can be freely tilted in order to discharge large processed products that have been nibbled, for example, from the plate material. However, there is a limit to the size of this unloading tilt table, and larger processed products cannot be transported out. .

An object of the present invention is to improve the above-mentioned problems by moving the plate integrally to a work supporting member that supports the plate so that the workpiece can be processed without causing scratches on the back surface of the plate. In addition to improving the commercial value of processed plate materials, by separating at least one of the workpiece support tables provided on both the left and right sides of the processing area from the other, it is now possible to drop and transport larger processed products than before. Our goal is to provide plate processing machines.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a workpiece support table section for supporting a workpiece on both left and right sides of a processing area in a plate processing machine, and provides at least one of the right and left workpiece support table sections. One of them was provided so as to be movable in a direction away from the work supporting table of the other, thereby configuring a plate processing machine.

Further, the present invention provides a workpiece support frame that extends to both left and right sides of a processing area in a plate processing machine, and a flexible workpiece support member having one end connected to the right end side of the workpiece support frame. a flexible workpiece, which is connected to a winding member rotatably provided adjacent to the right side of the processing area so that it can be wound up and unwound, and one end of which is connected to the left end side of the workpiece support frame; The other end of the support member is connected to a winding member rotatably provided adjacent to the left side of the processing area so as to be able to be wound up and unwound, and at least one of the winding members is connected to the other end of the supporting member. A plate processing machine was constructed by providing the plate material so as to be movable in a direction away from the winding member.

0010

[Operation] By adopting the plate material processing machine of this invention,
A workpiece support table portion for supporting a workpiece is provided on both left and right sides of a processing area in a plate processing machine. By moving at least one of the left and right work support table parts in the direction away from the other work support table part, a large gap is created between the left and right work support table parts, making it even more difficult than conventional large processed products. Large products are dropped downward and transported outside. Furthermore, since the plate is integrally supported by the left and right work support table sections and moved in the left-right direction, scratches are prevented from occurring on the back surface of the plate.

As it moves, the plate material W moves to the first and second positions.
Since the punching process is performed by moving integrally with the workpiece support members 15 and 21 in the X-axis and Y-axis directions, the back surface of the plate material W is not rubbed by the first and second workpiece support members 15 and 21. The processed plate material W (product) without scratches can have a higher commercial value than before.
