Description

Die Erfindung bezieht sich auf ein Formgebungsgerät für Hohlkörper, insbesondere Dosen.The invention relates to a shaping device for hollow bodies, in particular cans.

Herkömmliche Monoblocdosen besitzen einen nahtlosen zylindrischen Körper, der an seiner Oberseite einen koni­schen oder kugelförmigen Abschluß aufweist, in dem der Deckel mit Ventil eingesetzt ist.Conventional monobloc cans have a seamless cylindrical body which has a conical or spherical end on its top, in which the lid with valve is inserted.

Die Formgebung ist daher lediglich auf die Höhe, den Durchmesser und die Gestaltung des Abschlusses der Dose beschränkt.The shape is therefore limited to the height, the diameter and the design of the end of the can.

Der Dosenkörper selbst wird durch Fließpressen herge­stellt und der Abschluß durch Drücken mittels Gesenken in mehreren Arbeitsgängen ausgeführt. Das erfolgt in der Weise, daß die Gesenke von der offenen Seite des Dosen­körpers über den Mantel geschoben werden und diesen dreh­symmetrisch eindrücken. In neuerer Zeit sind auf diese Art auch zylindrische drehsymmetrische Querschnittredu­zierungen des Dosenkörpers hergestellt worden. Dadurch konnten Dosenkörper erstellt werden, die die Normsprünge in den Durchmessernormreihen zwischen dem normalen Dosen­körper und dem reduzierten Körperteil aufweisen, wodurch die Verwendung kleiner Deckel und Ventile möglich ist.The can body itself is produced by extrusion and the finish is carried out by pressing in several steps. This is done in such a way that the dies are pushed from the open side of the can body over the jacket and press it in rotationally symmetrically. More recently, cylindrical, rotationally symmetrical cross-sectional reductions of the can body have been produced in this way. This made it possible to create can bodies that have the standard jumps in the diameter standard series between the normal can body and the reduced body part, which means that small lids and valves can be used.

Natürlich ist auch denkbar, den Bereich durch Einführen eines Gesenkes aufzuweiten, doch sind dafür bisher nur Designüberlegungen maßgebend.Of course, it is also conceivable to expand the area by inserting a die, but so far only design considerations have been decisive.

Bei all diesen Verfahren liegt jedoch der Übergang zwi­schen den beiden Querschnitten in einer Ebene normal zur Drehachse des Dosenkörpers. Eine andere Möglichkeit der Formgebung kann darin bestehen, den Dosenkörper durch Sicken oder Rollen zu reduzieren oder zu erweitern.In all of these methods, however, the transition between the two cross sections lies in a plane normal to the axis of rotation of the can body. Another design option can be to reduce or expand the can body by beads or rollers.

Aus Kostengründen hat sich diese Methode aber nicht durchgesetzt.However, this method has not become established for cost reasons.

Aus Formgebungsgründen ist ein Absatz, bzw. Übergang zwi­schen dem reduzierten und nicht reduzierten Querschnitt der Dose gewünscht, der beliebig geformt ist. Mit den heute verwendeten Werkzeugen ist das nicht möglich. Denn: durch einen, zur Dosenachse nicht normalen Absatz wird ein ungleicher Druck auf den Dosenkörper ausgeübt und de­formiert diesen über einen weiten Bereich, wobei die Wand der Dosen in Falten gezogen wird.For reasons of shape, a step or transition between the reduced and non-reduced cross-section of the can is desired, which is of any shape. This is not possible with the tools used today. Because: due to a heel that is not normal to the can axis, uneven pressure is exerted on the can body and deforms it over a wide area, whereby the wall of the cans is drawn in folds.

Erfindungsgemäß wurde für diesen Zweck ein Werkzeug ge­schaffen, daß aus einem hohlen Außengesenk, mit drehzy­lindrischem Innenraum und einem Innengesenk mit drehzy­lindrischer Außenfläche besteht, das Innengesenk im Außengesenk konzentrisch angeordnet ist und eines der beiden Gesenke einen Absatz beliebiger Form an seiner drehzylindrischen Wand als Übergang zwischen zwei Dreh­zylindern mit gleicher Achse aufweist.According to the invention, a tool was created for this purpose that consists of a hollow outer die, with a cylindrical interior and an inner die with a cylindrical outer surface, the inner die is arranged concentrically in the outer die and one of the two dies has a paragraph of any shape on its cylindrical wall as a transition between two Has rotary cylinders with the same axis.

Durch die Verwendung des Innengesenkes wird die ungleiche Belastung des Dosenkörpers durch das Außengesenk verhin­dert, da das Innengesenk die Belastung aufnimmt. Dadurch bleibt der Dosenkörper gerade und eine Verformung erfolgt nur im Bereich des Eindrückens des Absatzes im Gesenk.By using the inner die, the uneven loading of the can body by the outer die is prevented, since the inner die absorbs the load. As a result, the can body remains straight and deformation occurs only in the area of the indentation of the heel in the die.

Falls der Flaschenkörper sich zu seiner offenen Seite hin verjüngt, ist es besonders günstig, das Formgebungsgerät so auszuführen, daß das Außengesenk einen beliebig ge­formten Absatz aufweist.If the bottle body tapers towards its open side, it is particularly favorable to design the shaping device in such a way that the outer die has an arbitrarily shaped shoulder.

Ein besonders günstiges Verfahren zur Herstellung eines Dosenkörpers für eine Dose mit reduziertem Oberteil und beliebig geformten Absatz aufweist.A particularly inexpensive method for producing a can body for a can with a reduced upper part and arbitrarily shaped paragraph.

Ein besonders günstiges Verfahren zur Herstellung eines Dosenkörpers für eine Dose mit reduziertem Oberteil und beliebig geformten Absatz zwischen den beiden Teilen kann so erfolgen, daß zuerst die Dose in an sich bekannter Weise von ihrer offenen Seite her im Querschnitt redu­ziert wird und danach die Dose mit der offenen Seite voran in das Formgebungsgerät zwischen die beiden Gesenke bewegt wird, der Absatz am Außengesenk dabei in Richtung zum nichtreduzierten Bereich der Dose weist, die Drehzy­linderdurchmesser des Außengesenks etwa dem reduzierten bzw. dem normalen Dosenaußendurchmesser, der Drehzylin­derdurchmesser des Innengesenks etwa dem reduzierten Do­seninnendurchmesser entspricht und dieser Bereich durch den, sich über ihn drückenden Absatz und Zylinderfläche an der Außenwand des Innengesenks zu liegen kommt, wobei die Dosenwand durch die beiden Gesenke beidseitig der Um­formstelle geführt ist.A particularly favorable method for producing a can body for a can with a reduced upper part and any shaped paragraph between the two parts can be done so that the can is first reduced in cross-section from its open side in a known manner and then the can with the is moved open side into the forming device between the two dies, the shoulder on the outer die points towards the unreduced area of the can, the rotary cylinder diameter of the outer die approximately corresponds to the reduced or normal outer diameter of the can, the rotary cylinder diameter of the inner die corresponds approximately to the reduced inner diameter of the can and this area comes to rest on the outer wall of the inner die due to the heel and cylinder surface pressing over it, the can wall being guided through the two dies on both sides of the forming point.

Bei diesem Verfahren wird der reduzierte Teil des Dosen­körpers zwischen den Gesenken geführt und das Wandmate­rial kann während des Drückvorganges zwischen die beiden Gesenke fließen und erhält dabei die Gestalt, wie der be­reits vorher reduzierte Teil. Ein Ausweichen der Dosen­körperwand ist somit vermieden.In this method, the reduced part of the can body is guided between the dies and the wall material can flow between the two dies during the pressing process and thereby receives the shape like the previously reduced part. Avoiding the can body wall is avoided.

Die drehsymmetrische Verjüngung der Dosen hat sich des­halb als vorbereitender Schritt für diese neue Formge­bungsmethode als vorteilhaft erwiesen, da dadurch ledig­lich der beliebige Absatz auf dem Dosenkörper mit einem Arbeitsschritt hergestellt zu werden braucht und der be­reits reduzierte Teil als zusätzliche Stütze des Dosen­körpers zur bekannten Halterung am Dosenboden dient.The rotationally symmetrical tapering of the cans has therefore proven to be advantageous as a preparatory step for this new shaping method, since all that is required is to produce any paragraph on the can body in one work step and the already reduced part as additional support for the can body to the known holder on the can base serves.

Um den Absatz noch weiter in einer regelmäßigen, über den Umfang des Dosenkörpers wiederkehrenden Form zu gestalten ist es auch möglich, daß nach Abschluß des Formgebungs­vorganges wenigstens einmal die Dose zurückgezogen, axial verdreht, neuerlich vorbewegt und der nichtreduzierte Do­senteil jeweils weiter verformt wird.In order to shape the sales even more in a regular form that recurs over the circumference of the can body it is also possible that after the shaping process has been completed, the can is withdrawn at least once, axially rotated, moved forward again and the non-reduced can part is further deformed in each case.

So kann man mit einem Außengesenk verschiedene Absätze am Dosenkörper herstellen.So you can create different heels on the can body with an external die.

Nach Formgebung des Absatzes kann man den Dosenkörper im reduzierten, näher zur Dosenöffnung befindlichen Teil in an sich bekannter Weise wieder aufweiten und einen Ab­schluß aufdrücken.After shaping the heel, the can body can be widened again in the reduced part closer to the can opening in a manner known per se and a closure pressed on.
