Abstract

Zur Herstellung von Dosenrümpfen mit unrundem Querschnitt, vorzugsweise mit einem rechteckförmigen Querschnitt mit abgerundeten Ecken werden flache Zuschnitte (3) zunächst in einer Verformungsstation (5) mittels einer Mehrzahl von gleichartigen Biegewerkzeugen (20) zur Herstellung jeweils einer Abbiegung verformt, wobei an den taktweise weitertransportierten Zuschnitten (3) gleichzeitig an den verschiedenen Zuschnitten jeweils eine andere Abbiegung hergestellt wird. Das Biegewerkzeug (20) weist ein innenseitig stationär gehaltenes Formstück (21) mit einer gekrümmten Aussenfläche (22) auf und ferner eine in einem Lagerungskörper (23) gelagerte Rolle (24), die unter der Wirkung einer gegen den Lagerungs­ körper (23) andrückenden Feder (26) steht, um den zwischen dem Formstück (21) und der Drückrolle (24) befindlichen Zuschnitt (3) während der durch eine an dem Lagerungskörper (23) angelenkte Hubstange (28) bewirkten Bewegung nach oben umzubiegen. Dies erfolgt gleichzeitig bei allen für jeweils eine Abbiegung vorgesehenen Biegewerkzeugen (20) durch einen beweglichen Teil (7) der als Presse arbeitenden Verformungseinrichtung (5). Der Zuschnitt (3) wird taktweise von einer zur nächsten Biegeeinrichtung (20) weiterbewegt, so dass nach mehreren Arbeitstakten ein Dosenkörper mit rechteckförmigem Querschnitt und abgerundeten Ecken vorhanden ist, dessen Ränder in einer nachfolgenden Schweissstation durch elektrisches Wider­ standsschweissen verbunden werden. For the production of canned hulls with a non-round Cross section, preferably with a rectangular Cross sections with rounded corners become flat blanks (3) first in a deformation station (5) by means of a plurality of similar bending tools (20) deformed to produce a turn, wherein on the blanks transported in cycles (3) simultaneously on the different cuts another turn is made. The bending tool (20) has an internally held shaped piece (21) with a curved outer surface (22) on and furthermore, one mounted in a bearing body (23) Roller (24) under the action of one against the bearing body (23) pressing spring (26) stands around the between the fitting (21) and the pressure roller (24) Blank (3) during the by one on the storage body (23) articulated lifting rod (28) caused movement after to bend up. This is done simultaneously for everyone for bending tools provided for one bend each (20) by a movable part (7) as a press working deformation device (5). The cut (3) is cycled from one bending device to the next (20) moved on, so that after several work cycles a can body with a rectangular cross section and rounded corners are present, the edges of which are in one subsequent welding station by electrical resistance welded together.
