Abstract
A punching device is provided with a punching head, a vacuum apparatus, a suction flow passage, and a suction switching apparatus. The punching head includes a plurality of hollow rods that move vertically, and punching tools each having an axially extending through hole provided at each front end of the hollow rods. The vacuum apparatus serves to suck punched chips generated during the punching process of the punching head. The suction flow passage selectively communicates the through holes of the punching tools with the vacuum apparatus. The suction switching apparatus changes a path of the suction flow passage so that the suction flow passage communicates only with a hollow rod performing a punching process, among the plurality of hollow rods.
