Abstract

Zur Herstellung von Dosenkörper, wie sie zur Herstellung von Aerosoldosen oder Getränkedosen gewünscht werden, wird ein spezielles Werkzeug (2) geschaffen, das sowohl die Napfherstellung wie auch die Umformung des Napfes zum Dosenkörper in einem Werkzeug (3) zusammenfasst. Es wird von vorzugsweise runden Platinen (18) ausgegangen, die in einer Abstreckstufe des Werkzeugs (2) in einem ersten Schritt zunächst zu Näpfen gezogen und dann in einem zweiten Ziehvorgang, dem Weiterzug- und Gleit-Zieh-Abstreckvorgang, zu Dosenkörpern abgestreckt werden. Die Ziehrichtungen sind in beiden Arbeitsstufen gleich. Es ergeben sich einfache robuste Werkzeuge und ein einfacher robuster Herstellungsprozess.

For the production of can bodies, as they are desired for the production of aerosol cans or beverage cans, a special tool (2) is provided, which summarizes both the Napfherstellung as well as the deformation of the cup to the can body in a tool (3). It is assumed that preferably round plates (18), which are drawn in an ironing step of the tool (2) in a first step first to wells and then in a second drawing process, the on-drawing and sliding-drawing-ironing, are stretched to can bodies. The draw directions are the same in both work stages. This results in simple, robust tools and a simple, robust manufacturing process.
