ABSTRACT:
Punching-nibbling press, in particular for sheet metal or the like includes at least one punch or stamp mounted coincident with a coaxial die or mold. The punch can be moved in the direction of the die, executing a punching-nibbling stroke towards the die and against a workpiece interposed between the die and the punch, and a stroke of withdrawal from the die and from the workpiece. The punching-nibbling press is provided with vacuum chambers for screening, suppressing or removing noise generated by the press. The vacuum chambers surround the punch and the die. The vacuum chamber which surrounds the punch is in the form of a hood which adapts to the position of the punch during its stroke and always remains active during the latter.
