Description

Bei der Herstellung von Deckeln für runde oder urrunde Konservendosen tritt der Nachteil auf, daß es infolge des verhältnismäßig starken Verschleißes der Anrollwerkzeuge ohne dauernde Überwachung nicht gelingt, mit diesen Rollen lange Zeit eine große Anzahl genau kalibrierter Deckel zu erzielen, die insbesondere genau gleich hole Anrollungen am Deckelrand auf-«-eisen. Diese stets gleiche Anrollhöhe ist aber nicht nur für die Dichtigkeit des VerschlußfaLes der Konservendosen von ausschlaggebender Bedeutung, sondern beeinflußt auch die Stapelfähigkeit der Deckel, die bei dem automatischen Betrieb in der Herstellung der Konservendosen sehr wichtig ist, wenn Ausschuß vermieden und der Gang der Fließfertigung nicht beeinträchtigt werden soll.In the manufacture of lids for round or round food cans the disadvantage arises that it is due to the relatively heavy wear the roll-on tools do not succeed for a long time with these roles without constant monitoring Time to achieve a large number of precisely calibrated lids that are particularly accurate Immediately pick up curls on the edge of the lid - «- iron. This always the same roll-on height but is not only for the tightness of the closure of the tin cans of decisive importance, but also influences the stackability of the lid, which is very important in the automatic operation in the manufacture of the cans is when rejects are avoided and the flow of production is not impaired shall be.

Zur Lösung der gestellten Aufgabe wird gemäß der Erfindung eine Vorrichtung mit zwei Stauchwerkzeugen zur Herstellung der Anrollung verwendet, derart, daß man mit dem ersten Werkzeug einen Hoctborddeckel erzeugt und dann mit dem zweiten Stauchwerkzeug durch eine darin vorgesehene schräge Ringfläche das Anrollen des Deckelrandes bewirkt.According to the invention, a device is used to achieve the object used with two upsetting tools to produce the curl, such that one with the first tool a hoct board cover is created and then with the second upsetting tool causes the edge of the lid to roll on by an inclined annular surface provided therein.

Die Herstellung des Hochborddeckels kann in zwei Arbeitsgängen unterteilt werden, nämlich in der Herstellung eines Flachborddeckels in einer Stanzpresse und in der Umwandlung des Flachborddeckels durch ein Stauchwerkzeug in einen Hochborddeckel.The manufacture of the high curb can be divided into two operations be, namely in the production of a flat rim in a punch press and in the transformation of the flat curb into a high curb using an upsetting tool.

Zur Erläuterung der Erfindung sei auf die Zeichnung erwiesen.To explain the invention, reference is made to the drawing.

In Fig. I ist im Querschnitt ein in einer Stanzpresse erzeugter Flachborddeckel a dargestellt, der in ein in Fig. 2 im Querschnitt gezeigtes, aus Oberteil b und Unterteil c bestehendes Stanzwerkzeug eingelegt wird. Die in Richtung des eingezeichneten Pfeiles x (Fug. 3) hochgehenden Teile b, c führen den Flachborddeckei a gegen einen ortsfesten Ring d, der den Rand des Deckels nach unten umlegt und auf diese Weise einen Hochborddeckel a erzeugt. Dieser Hochborddeckel a wird dann in das zweite, aus dem Oberteil e und dem Unterteil f bestehende Stauchwerl=seug (Fug. g) eingeführt, von dem das Unterteil eine schräge Ringfläche g am Rand aufweist. Werden die Zeile dieses zweiten Stauchwerkzeugs zusammengeführt, wie das Fig. 5 zeigt, so entsteht aus dem Hochborddeckel a1 (Fug. 4.) ci.i genau kalibrierter Anrolldeckel a" (Fug. 5) mit stets genau gleich großem Außendurchmesser. Die stets genau gleiche Höhe der Anrallung wird dadurch gewährleistet, daß beim Zusammenführen von Oberteil und Unterteile, f die Bewegung sicher genau begrenzt werden kann.In FIG. 1, a flat rim a produced in a punch press is shown in cross section, which is inserted into a punching tool which is shown in cross section in FIG. 2 and consists of upper part b and lower part c. The parts b, c rising in the direction of the arrow x (Fig. 3) lead the Flachborddeckei a against a stationary ring d, which folds the edge of the lid downwards and in this way creates a high curb a. This high curb a is then inserted into the second, consisting of the upper part e and the lower part f Stauchwerl = seug (Fug. G), of which the lower part has an inclined annular surface g at the edge. If the line of this second upsetting tool is brought together, as shown in FIG. 5, the high curb lid a1 (fug. 4.) ci.i precisely calibrated roll-on lid a "(fug. 5) with an outer diameter of exactly the same size is created the same amount of contact is ensured by the fact that when the upper part and the lower part are brought together, the movement can be reliably and precisely limited.

Wesentlich für die ausschußfreie Herstellung von kalibrierten, angerollten Konservendoserdeckeln ist, daß der der schrägen Ringfläche g gegenüberliegende Rand lz im Stauchwerkzeugoberteil e so vorgezogen ist, daß er dicht an der Außenrundung des Hochborddeckels a1 anliegt und ein sicheres Abstützwiderlager beim Anrollen ergibt.It is essential for the scrap-free production of calibrated, rolled-on tin can lids that the edge lz opposite the inclined annular surface g is preferred in the upsetting tool upper part e so that it lies close to the outer curve of the high curb lid a1 and provides a secure support abutment when rolling.

Die Ober- und Unterteile der Stauchwerkzeuge können auch miteinander vertauscht sein.The upper and lower parts of the upsetting tools can also be connected to one another be swapped.
