Abstract

1,074,339. Punching - machines. R. SCHWORER. June 29, 1965 [July 1, 1964], No. 27534/65. Heading B4B. In a machine for making a row of holes in a pack of sheets comprising a work-table 1, a vertically-movable clamping beam 2 and a vertically-movable drilling complex equipped with a row of drills 16 spaced equidistantly from each other, the drilling complex being continuously displaceable in the axial direction of the drills and displaceable stepwise in a direction normal to the drill axes, the work-table and the clamping beam each having a row of guide holes 3 or 4 for the drills and the distance between each two neighbouring drills being a multiple of the distance between the axes of each two neighbouring guide holes, each drill is a hollow tubular punch drill the cutting edge 16a of which tapers inwardly to form a frusto-conical hollow 17a. The drill chuck 7 has an opening 7a through which the punched-out chips pass to a channel 8 to which a suction device is connected. The drive pulleys, e.g. 9a are operated together in groups of five by means of an endless belt and a driving pulley driven by its own electric motor and each belt being provided with a tensioning belt which can be retracted by means of a manually-operable spring-influence lever. The raising, lowering and advancing movements of the drill complex can be effected hydraulically.
