Abstract

An apparatus is disclosed having one or more punching or stamping tools and a corresponding number of support tools for mating with each punching or stamping tool. The apparatus is adapted to form dimples, impressions, cuts, apertures or otherwise similarly modify the surface of a sheet metal blank, and in which the punching and support tools are both movably provided along a supporting structure formed from two elongated and parallel spaced beam members. Each beam member supports one of the punching tool, or stamping tool, and the support tool in a spaced relationship whereby the tools may be aligned and activated in punching or stamping operation to punch or stamp a portion of a blank positioned therebetween. A conveyer is provided to move the blank between the tools so that the portion of the blank to be modified is moved to a position intersecting the path of movement of the punching or stamping tool and the supporting tool. The advancement of the blank on the conveyor and/or the movement of the punching or stamping tool and the support tool along the supporting structure is controlled so that dimples, apertures, and the like may be formed at any desired portion of the blank.
