PRESSA DI PUNZONATURA CON MEZZI PER SOSTENERE UN PEZZO IN LAVORAZIONE DURANTE LA SUA FORATURA,IN PARTICOLARE ASSOCIABILE AD UN CANNELLO DI TAGLIO

摘要

A workpiece is shifted forwardly and rearwardly beneath a punch and a transversely spaced cutting torch by a work table formed with a comparatively wide fore-and-aft extending throat for accommodating a die and a duct which underlie the punch and the torch, respectively. The throat is partially filled by platforms which normally support the overlying portions of the workpiece to reduce deflection thereof but which are adapted to be automatically moved out of the way of the rear of the table when the table is shifted forwardly.
