DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the accompanying drawings by embodiments.
FIG. 1 is a diagram showing an embodiment of the present invention, and a punch cutting complex machine shown in the figure has a punching section and a cutting section that are adjacent to each other.
[0015]
Of these, the punching section has an upper turret 6 and a lower turret 7 as shown in the figure, and the upper turret 6 has a punch P and the lower turret 7 has a die D.
[0016]
The rotation shaft 8 (FIG. 5A) of the upper turret 6 and the rotation shaft 9 of the lower turret 7 are wound with the chains 4 and 5, respectively, and the chains 4 and 5 are connected to the drive shaft 3. It is wound around.
[0017]
With this configuration, if the chains 4 and 5 are circulated by rotating the drive shaft 3 by the motor M, the upper turret 6 and the lower turret 7 rotate synchronously, so that the punch P and the die D at the punching position K1. A predetermined mold M can be selected.
[0018]
Also, a ram cylinder 2 for hitting the punch P is provided on the frame 1 of the punched portion main body immediately above the punch P at the punching position K1, and the workpiece is supported by the cooperation of the punch P and the die D. A predetermined punching process can be applied to W.
[0019]
In this case, the punch P (FIG. 5B) is disposed in the punch guide 51, and the punch guide 51 is supported by the upper turret 6 via a lift spring 52. The punch guide 51 includes a stripper spring 53. The punch head 54 at the top of the punch P is supported through the.
