According to the present embodiment as described above, the laser beam machining head 49 and the punch die machining head 23 are connected and disconnected by the operation of the connection / interruption device 63 so that the laser machining head 49 and the punch die machining head 23 are connected. It can be integrated or separated. Therefore, when punching is performed, the laser machining head 49 is separated from the punch die machining head 23 and positioned at a position away from the punching area A, so that vibrations due to punching are transmitted to the laser machining head 49. Can be suppressed as much as possible. When performing laser processing, the laser processing head 49 and the punch die processing head 23 are integrated, and the laser processing head 49 is integrated with the punch die processing head 23 by the operation of the first servomotor 39 and the ball screw 31. Since it is possible to move and position in the vertical direction, it is not necessary to separately provide a servo motor and a ball screw for moving the laser processing head 49, and it is possible to reduce the cost.

[0036]

As can be understood from the above description of the embodiments, according to the present invention, the thermal cutting processing head and the die processing head are connected and cut off by the operation of the connection / interruption device, so that the heat is cut off. The cutting head and the punch die head can be integrated or separated. Therefore, when punching, the thermal cutting head is separated from the die processing head, and when it is separated from the punching area, it is positioned so that vibration due to punching is transmitted to the thermal cutting head as much as possible. You can hold it down. Also, when performing heat cutting processing, integrate the heat cutting processing head and the mold processing head,
By operating the control motor and screw rod, the thermal cutting processing head can be moved and positioned integrally with the die processing head in a predetermined direction, so a separate control motor and screw rod for moving the thermal cutting processing head are required. Therefore, the cost can be reduced.
