[0005]

[Problems to be solved by the invention]

However, when a hole is formed in the work W using the punch p and the die d shown in FIG. 12B, the work W may enter the adjacent cut processing portion. is there.

In this case, the L blade 140 on the cutting section side is
As shown in FIG. 13A, the upper blade 141 and the lower blade 142 are configured.

The punching mode (FIG. 12)
In (B)), the upper blade 141 rises (FIG. 13B) and stands by upward, but the lower blade 142 is at the same height position as the processing table 143.

Therefore, the punching mode (FIG. 12)
In (B)), when the workpiece W enters the cutting section, the workpiece W conveyed via the clamp 113 on the machining table 143 (FIG. 13B) moves on the lower blade 142. Will pass.

As a result, the work W and the lower blade 142 (see FIG. 1)
3 (B)) The work W is damaged due to rubbing and the lower surface thereof being scratched, and the processing accuracy of the work W is reduced.

In order to solve this problem, conventionally, FIG.
As shown in FIG. 4A, a support table 144 for supporting the work W is provided inside the lower blade 142.

The support table 144 is moved in the left-right direction (X-axis direction) by a cylinder 146 (FIG. 14A).
And the cylinder 145 (FIG. 14 (B)) can be moved in the vertical direction (Z-axis direction).

With this configuration, in the punching mode (FIG. 14A), the cylinder 146 is actuated to move the support table 144 closer to the lower blade 142 and to move the cylinder 145 (FIG. 14B). Operate to lower the support table 144.

Thus, in the punching mode,
Even if the work W enters the cutting section and passes over the lower blade 142 (FIG. 14B), the work W is supported by the support table 144, and the lower surface is scratched or damaged. I do not receive.

When the punching mode is terminated and the mode is switched to the cutting mode, the cylinder 14 is again operated.

However, conventionally, as described above, two cylinders 14 are used to drive the support table 144.
6, 145, and the operation in the horizontal direction (X-axis direction) and the operation in the vertical direction (Z-axis direction) are performed independently without being continuous.

Therefore, for example, when the punching mode is terminated and the mode is switched to the cutting mode, the support table 144 moves away from the lower blade 142 (FIG. 15).
(A)) The moving time until the ascent further rises (FIG. 15B) becomes longer (for example, approximately 6.5 seconds).

As a result, it is apparent that the entire processing time is also long and the processing efficiency is reduced.

Conventionally, the support table 14
4 is mounted on a dedicated frame 148 together with a belt conveyor 147 for carrying out the cut product (FIG. 15A).

As a result, the support table 144 hinders the maintenance work of the belt conveyor 147, and the work performance is degraded.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the work efficiency of a work by shortening a moving time of a support table at the time of mode switching in a multifunction punching machine, and to mount the support table separately from a belt conveyor. Thus, the maintenance performance of the belt conveyor is improved.

[0023]

In order to solve the above-mentioned problems, according to the present invention, as shown in FIGS.
(A) A punching section for punching a work W by a punch P and a die D, and a work W
(B) A support table 30 for supporting a workpiece W in a punching mode is provided on a main body frame 45 of the above-mentioned cutting section in a punch cutting multifunction machine in which a cutting section for cutting a sheet is arranged adjacent to each other. A punch cutting multifunction machine is provided, wherein the support table 30 is attached and movable up and down continuously in an oblique direction.

According to the structure of the present invention, for example, the link base 21 is attached to the body frame 45 of the cutting portion (FIG. 1), and the link base 21 is arranged parallel to each other at a predetermined angle (FIG. 4). Cylinder 26 and link 2
The swing base 22 is attached via the bases 3, 24 and 25, and the support table 30 is attached to the swing base 22.
In the XYZ three-dimensional space (FIG. 5), for example, 0 is freely movable vertically in a diagonal direction between a descending position A and an ascending position B along an arc C, for example.

For this reason, when the support table 30 moves up and down at the time of mode switching in the multifunction punching machine, the operation of the up and down movement is performed continuously. For example, the mode changes from the cutting mode to the punching mode. When switching (FIG. 9), the support table 30 descends continuously in the oblique direction. For example, when switching from the punching mode to the cutting mode (FIG. 10), the support table 30 continuously rises in the oblique direction. Therefore, the moving time of the support table 30 is reduced as compared with the related art.

Further, since the support table 30 is attached to the main body frame 45 of the cutting section via the link base 21 or the like, the support table 30 can be attached separately from the belt conveyor 16.
0, the space below the belt conveyor 16 becomes available.
The maintenance performance of FIG. 1 can be improved.

Therefore, in the punch cutting multifunction machine, the working time of the support table at the time of mode switching is shortened to improve the processing efficiency of the work, and the support table is attached separately from the belt conveyor, so that the belt conveyor is attached. It is possible to improve maintenance performance.
