(Prior Art) A composite processing machine including a mechanical processing apparatus such as a punching machine and a thermal cutting apparatus such as a laser processing machine is generally configured as shown in FIG. That is, the turret punching machine 1 as a mechanical processing device is provided with the upper turret 5 and the lower turret 7 with respect to the frame 3. The upper turret 5 has various shapes on its circumference.
A punch 9 of a size is attached, and the lower turret 7 is provided with a die 11 of a shape and size corresponding to the punch 9 of each shape and size described above.

Further, a material clamp 13 is provided for the carriage 15 to feed the material to the punch 9 and the die 11, and the carriage 15 moves in the X-axis direction with respect to the carriage base 17. The carriage base 17 including the carriage 15 moves on the work table 19 in the Y-axis direction.

When performing mechanical processing such as punching on the material, the upper turret 5 and the lower turret 7 are rotated so that a set of a punch 9 and a die 11 having a predetermined shape and size is positioned directly below the impactor 23. Let Further, the carriage 15 and the carriage base 17 are respectively moved by a desired distance in the X-axis and Y-axis directions, and the desired processing position of the material is positioned between the selected punch 9 and die 11 by this XY two-dimensional movement. Of.

A laser processing head 25 as a heat cutting device is attached to the frame 3 so as to be located near the upper and lower turrets 5, 7. And this laser processing head

However, in a multi-tasking machine including such a heat cutting device, fumes containing fine iron oxide powder generated in the heat cutting device flow toward the turrets 5,7 and adhere to the turrets 5,7 and their tools 9,11. And how to protect the turrets 5, 7 and tools 9, 11 from fume becomes a problem.

Therefore, conventionally, as shown in FIG. 6, it is conceivable to increase the distance L between the punch center P of the turret 5 and the torch center Q of the laser processing head 25.

However, if the distance L between the punch center P and the torch center Q is increased in this way, there is a problem that a portion where the material cannot be composite-processed by the distance L, that is, the dead zone becomes large, and the material is wasted. is there.

Therefore, as shown in FIG. 7, a partition plate 31 may be provided between the turrets 5 and 7 and the laser processing head 25 to prevent fumes generated by laser processing from flowing in the turrets 5 and 7. ing.

However, even if the partition plate 31 is provided in this way, the material needs to be moved on the table 19 by the clamp 13, and a space corresponding to the thickness of the material is always provided between the partition plate 31 and the table 19. I have to go. for that reason,
As shown in FIG. 8, the fumes generated during the laser processing flowed through the gap to the turrets 5 and 7 side beyond the partition plate 31 and could be attached to the turrets 5 and 7 and the tools 9 and 11. .

(Embodiment) FIG. 2 shows an essential part of an embodiment of the present invention.
2 shows the essential parts of a multi-tasking machine equipped with the turret punching machine 1 shown in FIG. 1 and a laser processing head 25. A laser processing head 25 is provided adjacent to the upper turret 5, and a semicylindrical partition plate 33 is provided so as to surround about half of the circumference of the laser processing head 25.

That is, the partition plate 33 does not cover the entire circumference of the laser processing head 25, but is open on the opposite side of the turret over at least a semicircle range.

The partition plate 33 is rotated around the laser processing head 25 by a guide roller 37 with respect to a substantially cylindrical support 35 fixed to the frame 3. An inner peripheral rack 39 is formed on the lower inner periphery of the support body 35.

A collar 41 is provided on the outer periphery of the partition plate 33.
The guide roller 37 and the motor 43 are attached to. A pinion 45 is provided on the output shaft of the motor 43, and by meshing with the inner peripheral rack 39, the partition plate 33 is moved within the support 35 so that the laser processing head 25
It is configured to rotate around.

At the lower part of the partition plate 33, a dust collecting attachment 49 having a slit 47 formed so as to surround the laser processing head 25 over substantially the entire length is attached. A dust collecting duct 51 is connected to the dust collecting attachment 49. Therefore, the fumes or the like flowing along the upper surface of the material W toward the upper and lower turrets 5 and 7 are heat-cut from the slit 47 of the dust collecting attachment 49 through the dust collecting duct 51 by suction by a dust collector not shown. Fume generated from time to time can be sucked and removed.

The operation of the multi-tasking machine including the thermal cutting device having the above configuration will be described below.

When performing laser processing in this combined processing machine, as described above, the laser beam is guided from the laser oscillator 27 to the laser processing head 25 through the laser guide means 29, and a predetermined portion of the material W is irradiated with the laser beam. Cut and process.

At this time, although fumes containing iron oxide are generated, the partition plate 33 is provided with a laser processing head as shown in FIG. 2 so that the fumes do not flow out to the upper and lower turrets 5 and 7 sides of the turret punching machine 1. It is rotationally driven so as to be located between 25 and the upper turret 5. The partition plate 33 is moved by driving the motor 43 to rotate the pinion 45. That is, by the rotation of the pinion 45, the pinion 45 itself moves while rotating along the inner peripheral rack 39 in which the pinion 45 meshes, and the partition plate 33 also rotates and moves in the support body 35 by the guide of the guide roller 37 accordingly. It is moved to a predetermined position.

After positioning the partition plate 33 at the predetermined position in this way, a suction operation is performed by a dust collector (not shown) to pass the dust collecting attachment 49 through the dust collecting duct 51.
Sucks the fume through the slit 47 and prevents it from flowing out toward the turret 5.

The partition plate 33 is unnecessary when the laser processing by the laser processing head 25 is not performed, and may cause an obstacle for the punching operation. Therefore, by driving the pinion 45 by the motor 43 and rotating the partition plate 33 in the opposite direction around the laser processing head 25,
It can be evacuated to a position that does not cause an obstacle.

FIG. 4 shows another embodiment of the present invention. The partition plate 53 provided between the punching machine 1 side and the laser processing head 25 is a flat plate, and the dust collecting attachment 55 is the flat plate-shaped partition plate 53. The fumes generated by laser processing are sucked into the dust collecting attachment 55 through the dust collecting duct 59 and collected by the dust collector 61 through the dust collecting duct 59.

In the case of the embodiment in which the dust collecting attachment 55 is provided on the flat partition plate 53, the fumes generated by the laser processing are sucked by the dust collecting attachment 55 so as not to flow out to the turret 5 side of the turret punching machine 1. it can.

Further, as shown in FIG. 5, when the dust collecting attachment 55 for such a flat plate-like partition plate 53 is used, the partition plate 53 is allowed to escape upward together with the dust collecting attachment 55 when laser processing is not performed. Can be taken. That is, an elevating drive device 63 such as a cylinder is provided for the frame 3, and the elevating drive device 63 drives the partition plate 53 up and down. When not needed, the dust collecting attachment 55 is raised together with the partition plate 53, and the carriage 15 is moved. You can avoid getting in your way.

In this case, a bellows type or a double nesting type can be used so that the dust collecting duct 59 can expand and contract by the stroke thereof as the partition plate 53 moves up and down.
