Upper and lower turrets (not shown) are synchronously and rotatably supported inside the gate frame 103. Then, the upper mold attached to the upper turret is used as the gate frame 10
The work is punched by a ram (not shown) provided on the upper part of 3 and cooperation with the lower die attached to the lower turret.

A fixed center table 107, which is a member constituting the work table 105, is provided adjacent to the upper and lower turrets.
Side tables 109 are movably provided on both sides of the table 7. The side table 109 is integrally connected by a carriage base 111 extending in the front-rear direction while straddling the center table 107.

A carriage 113, which is movable in a direction orthogonal to the moving direction of the side table 109, is mounted on the carriage base 111. The carriage 113 has a side edge portion of a plate-shaped work. A graspable clamp device 115 is mounted so that its position can be adjusted.

With the above structure, the work held by the clamp device 115 provided on the carriage 113 is positioned at the punching position by the movement of the carriage 113 in the front-rear direction and the left-right direction, and the desired shape is punched. It

The structure for supporting the side table 109 is described in detail in FIG. That is, the members that support the side table 109 are the carriage base 111 and the rail 1 provided below the gate frame 103.
It is supported by an LM guide member 119 that is provided so as to hang down on the lower side of the side table 109 which is slidable on top of the side table 109. Further, the sub-guide roller 121 hung down from the tip of the side table 109 is provided with the sub-frame 103.
A rail member 125 supported on a sub-guide arm 123 protruding from the lower side surface of the rail is movable. As described above, the side table 109 is supported at three points and is movable.

[0007]

By the way, in the supporting structure of the side table 109 in the above-mentioned conventional turret punch press 101, three-point support is provided, and the supporting member is provided at the position indicated by the arrow A in the drawing of FIG. Is not provided.

Therefore, during punching, the arrow A of the side table 109 sways in the vertical direction to generate vibrations, which lowers punching accuracy.
Further, when an operator rides on the arrow A, the side table 109
However, there is a problem in that the workability and safety are deteriorated due to the bending.

An object of the present invention is to improve workability and safety by preventing the table from bending, and
It is an object to provide a work table in a plate material processing machine, which improves the punching accuracy by reducing the vibration.

[0010]

In order to achieve the above object, a work table in a plate material processing machine of the present invention according to claim 1 is a plate material provided with a center table and side tables movable on both sides of the center table. A work table in a processing machine is characterized in that guide members for guiding along a rail are provided at the front end portions in the moving direction on both sides in the lower lateral width direction of the side table.

Therefore, the side table is supported in a well-balanced manner, and even when an operator rides on the table to work, the table does not bend, and workability and safety are improved.

Further, in the work table of the plate material processing machine of the present invention according to claim 2, among the guide members, the guide member farther from the side surface of the frame provided on the plate material processing machine is a roller rolling on the rail. It is characterized in that the guide member formed of a member and provided on the plate material processing machine on the side close to the frame is formed of a roller member that rolls by sandwiching the rail in the vertical direction.

For this reason, the roller member, which is a guide member near the frame provided in the plate material processing machine, rolls by sandwiching the rail in the vertical direction and supports the work table, so that the work table itself vibrates. And the punching accuracy is improved.
