And a punch head and a die head that are movable in the up and down directions, respectively, and are equipped with a laser head and a laser fume catcher head that face each other adjacent to the punch head and the die head. The laser fume catcher head is provided with a shower nozzle for discharging spatter, fumes and the like to the outside.

It is desirable that the composite processing machine be provided with an absorption processing device below the shower nozzle for simultaneously absorbing spatter and fumes together with the liquid ejected by the shower nozzle.

[0007]

By using the multi-tasking machine of this invention,
In a vertical punching machine, a punch head and a die head are provided with a punch and a die in cooperation with each other to perform punching and forming processing on a work, and laser processing such as trimming by a laser head provided adjacent to the punch head and the die head.

Laser machining is performed into a desired shape by moving the laser fume catcher head 65 of No. 3 in the Y-axis direction and moving the work W in the X-axis direction. It should be noted that spatters, fumes, and the like generated during laser processing are sucked by the laser fume catcher head 65 and discharged through the telescopic pipe 67 and the liquid tank 69 to the outside of the machine.

With the above-described structure, the punch head 17, the laser head 41, the die head 19, and the laser fume catcher head 65 are synchronously driven by the vertical drive motors 21 and 23 in the Y-axis direction.

During punching, since the punch P is mounted on the punch head 17 and the die D is mounted on the die head 19, the punching and forming processes are carried out with the coaxiality of, for example, about 4/100 mm to 5/100 mm. Is applied.

During laser processing, the work W is fed in the X-axis direction by the offset amount α (see FIG. 2). That is, processing is performed with the origin shifted by an amount α. At this time, the degree of coaxiality required for punching is not required.

By the way, since spatter and fumes generated during laser processing have an irritating odor, it is not preferable to release them to the outside air. Therefore, in the sputter / fume absorption processing apparatus, as shown in FIG. 1, between the liquid tank 69 installed on the base 3 and the laser fume catcher head 65, it is possible to expand and contract vertically and to the outside air. A telescopic pipe 67 having a tight sealing property is provided. The liquid tank 69 is elongated in the left-right direction, and the lower end of the telescopic pipe 67 is attached to the upper surface on the right side. A liquid L such as water is stored in the liquid tank 69 about 2/3 from the bottom, and a plurality of filters 71 made of, for example, resin material are provided below the liquid surface on the left side of the mounting portion of the telescopic pipe 67. It is provided. Further, below the liquid surface on the left side of the filter 71, a suction filter 73 made of, for example, a cylindrical paper filter is provided, and the liquid L filtered by a pump 77 provided on the upper surface of the liquid tank 69 via a suction pipe 75. To supply. Then, the discharge side of the pump 77 and the laser fume catcher head 65.
A flexible hose 79 is provided between the upper part and the upper part.

A shower head 81 is provided at the upper end inside the laser fume catcher head 65 and is connected to the tip of the flexible hose 79. The shower head 81 is adapted to diffuse the liquid L downward. On the other hand, the suction filter 7
A plurality of partition walls 83 are provided in a zigzag pattern below and above the liquid surface in the liquid tank 69 on the left side of 3. A plurality of shower heads 85 are provided in the upper surface of the liquid tank 69 between the partition walls 83 to diffuse the liquid L downward. Liquid is supplied to these shower heads 85 from branch pipes 87 and 89 of the flexible hose 79. Further, a vacuum blower 93 is provided at the left end on the liquid level of the liquid tank 69 via a plurality of paper-made filters 91, for example.

With the above construction, when the vacuum blower 93 and the pump 77 are operated and the laser beam LB is applied to the work W from the laser nozzle 61, spatters S, fumes H, etc. are sucked into the laser fume catcher head 65. Then, the spatter S, the fume H, and the like are entrained in the liquid L ejected and diffused from the shower head 81, are swept downward in the telescopic pipe 67, and are struck on the liquid surface in the liquid tank 69. Then, spatters S and large sludges are sunk as they are below the liquid surface and further settled on the bottom of the liquid tank 69. Most of the fumes H also dissolve in the liquid L.

However, since the pump 77 is operating and the liquid L is constantly sucked from the suction filter 73, the liquid L flows from right to left in the liquid tank 69. Therefore, the fine processing sludge and the spatter S are mostly filtered by the plurality of filters 71. Therefore, the suction filter 73 only filters fine dust.
Further, the fumes H, smoke, etc., which have not been dissolved by the spray of the liquid L from the shower head 81, move leftward on the liquid surface and meander vertically through the plurality of partition walls 83 provided in zigzag. , Is completely dissolved in the liquid L by spraying from the plurality of shower heads 85 and falls below the liquid surface. further,
The air or gas from which the fumes H, smoke, and the like have been removed passes through the remaining partition wall 83 while the liquid L (water) is removed and reaches the left end of the liquid tank 69. Then, the moisture is completely removed by passing through the plurality of filters 91, and then sucked by the vacuum blower 93 and released to the outside air.

As described above, according to this embodiment, since the laser head 41 and the laser fume catcher head 65 are processed in synchronization with each other, the laser fume catcher head 65 remains the spatters S and fumes H generated during laser processing. Since it can be reliably caught without spatter S, spatter S, processing scrap, fume H, and the like are not scattered around the work W.

Further, the sputter / fume absorption processing device 6
3 is a vacuum blower 9 due to the spraying of the liquid L from the shower heads 81 and 85 and the action of the filters 71 and 91 in a sealed container composed of the laser fume catcher head 65, the telescopic pipe 67 and the liquid tank 69.
The air or gas sucked from 3 and released to the outside air is completely harmless and has a great effect on safety and hygiene.

Since the punch forming process and the laser cutting process can be combined with each other without concern about scattering of the spatter S and fume H and contamination of the outside air, the forming portion after the punch forming process is not deformed. Processing such as trimming can be performed without lowering processing accuracy.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. For example, in the present embodiment, the laser head 41 is provided in parallel with the X-axis direction of the punch head 17, but the laser head 41 may be provided in the Y-axis direction of the punch head 17.

[0035]

As will be understood from the above description of the embodiments, according to the present invention, since the construction is as described in the claims, the punch head and the laser head are provided adjacent to the die head. Laser fume catcher heads are provided facing each other and driven synchronously to perform punching, forming and laser processing.

Therefore, after the punch forming process, the process can be performed without deforming the forming portion, and the spatter generated during the laser processing can be performed without lowering the processing accuracy.
Since the fumes and the like are sucked by the absorption processing device and discharged to the outside of the machine, it is possible to prevent scattering of spatter, fumes and the like, and it is possible to perform laser processing without contaminating the outside air.
