Abstract

Bei einer Vorschubvorrichtung zum Zuführen von Blechtafeln (2) zu wenigstens einem stationären Stanzwerkzeug (11), mit dem aus den Blechtafeln (2) Platinen (10) ausgestanzt werden, mit einem in Vorschubrichtung auf einem Fördertisch (6) verfahrbaren, einseitig gelagerten Vorschubbalken (7, 8) mit die Blechtafel (2) ergreifenden Spannzangen (21), die am Vorschubbalken (7, 8) quer zur Vorschubrichtung seitlich verfahrbar sind, läßt sich der Stanzvorgang beim Übergang von einer Blechtafel (2) zu einer anderen ohne Leerhub durchführen, wenn ein zweiter Vorschub­ balken (7, 8) vorgesehen ist, wenn beide Vorschubbalken auf jeweils einer anderen Längsseite des Vorschubtisches (6) einseitig gelagert sind und wenn beide Vorschubbalken jeweils um ein mit seiner Achse in Förderrichtung zeigendes Drehgelenk (25) hochschwenkbar sind. With a feed device for feeding metal sheets (2) at least one stationary punching tool (11) with which the Metal sheets (2) boards (10) are punched out with a Feed direction movable on a conveyor table (6), feed beam (7, 8) on one side with the metal sheet (2) gripping collets (21) on the feed beam (7, 8) are laterally movable transversely to the feed direction, the Punching process in the transition from a metal sheet (2) to one perform another without idle stroke if a second feed bar (7, 8) is provided when both feed bars on a different longitudinal side of the feed table (6) are supported on one side and if both feed bars are each around a swivel joint (25) with its axis pointing in the conveying direction can be swung up.
