Description

Die Erfindung betrifft ein Verfahren zumWarmaufschrumpfen von Stand- oder Rollringen auf nahtlos gezogene oder gedrückte Gefäße aus, Aluminium oder Aluminiumlegierungen, insbesondere Milchkannen. . .. .The invention relates to a method for heat shrinking stand- or rolling rings on seamlessly drawn or pressed vessels made of aluminum or aluminum alloys, especially milk cans. . ...

Es ist bekannt, dieKannenwand an der Schrumpfstelle mit etwa -zweifacher Stärke der übrigen Kannenwand auszuführen, um große radiale Pressungen von außen her ausüben und in der Kannenwand tiefe Nuten oder eine Schulterfläche für einen zahnartigen Eingriff des Werkstoffes des Ringes vorsehen zu können.It is known that the can wall at the shrinkage point is approximately twice as high Make the thickness of the rest of the can wall in order to avoid large radial pressures from the outside and deep grooves or a shoulder surface for one in the can wall To be able to provide tooth-like engagement of the material of the ring.

Ferner ist es bekannt, Rollreifen zwischen in die Gefäßwand eingewalzten Rillen warm aufzuschrumpfen. Hierdurch entstehen an der Innenseite der Wand Vertiefungen, in denen sich Schmutz und Rückstände ansammeln können, ohne daß die Möglichkeit besteht, sie bei einem normalen Reinigungsverfahren restlos zu beseitigen. Das ist, bei für Nahrungsmittel bestimmten Gefäßen nicht angängig und würde sogar den Vorschriften der Gesundheitsbehörden zahlreicher Länder zuwiderlaufen.It is also known to roll hoops rolled into the vessel wall Shrink grooves warm. This creates indentations on the inside of the wall, in which dirt and debris can collect without the possibility consists in removing them completely using a normal cleaning process. That is, Not applicable for containers intended for food and would even comply with the regulations contrary to the health authorities of numerous countries.

Gemäß der Erfindung wird die Kannenwand vor dem Aufschrumpfen des Ringes an der Schrumpfstelle mit einer nach außen gerichteten Ausbeulung versehen, die von der Schrumpfspannung des Ringes, dessen innerer Durchmesser im kalten Zustand gleich dem ' Außendurchmesser des Gefäßes ist, wieder eingeebnet wird. Hierdurch erhält man auf einfache Weise eine außerordentlich große Schrumpfspannung, die eine zuverlässige. Verbindung des Ringes mit der an ihrer Innenseite völlig glatten und an der Schrumpfstelle keinerlei Verstärkungen --=aufweisenden - Kannenwand sichert. Zusätzlich kann man die Innenseite des Ringes in- an sich bekannter Weise mit Aufrauhungen versehen, die sich- beim--Aufschrumpfen des Ringes in die weichere Außenhaut der Gefäßwandung eindrücken. ' -Die Erfindung ist an Hand der Zeichnung veranschaulicht.According to the invention, the can wall is before shrinking the The ring at the shrinkage point with an outward bulge, that of the shrinkage tension of the ring, its inner diameter when cold is equal to the 'outside diameter of the vessel, is leveled again. Through this one obtains in a simple manner an extremely large shrinkage stress, the one reliable. Connection of the ring with the completely smooth on its inside and at the shrink point no reinforcements - = having - secures the can wall. In addition, the inside of the ring can be roughened in a manner known per se provided that - when - shrinking the ring into the softer outer skin of the Press in the wall of the vessel. The invention is illustrated with reference to the drawing.

Fig:. i zeigt den .Zustand vor dem Schrumpfen des Rollringes; die hierbei noch vorhandene, an der Schrumpfstelle nach außen gerichtete Ausbeulung der Kannenwand ist übertrieben dargestellt; Fig. 2 zeigt den Zustand nach dem Erkalten. Der auf kleineren Durchmesser eingeschrumpfte Ring hat die Ausbeulung der Kannenwand eingeebnet. Die an der Innenseite des Ringes vorgesehenen Unebenheiten haben sich in die weiche Außenhaut der Gefäßwand eingedrückt.Fig :. i shows the .Stand before the shrinkage of the rolling ring; the here still existing bulge at the shrinkage point facing outwards the can wall is shown exaggerated; Fig. 2 shows the state after cooling. The ring shrunk to a smaller diameter has the bulge of the can wall leveled. The bumps provided on the inside of the ring have become pressed into the soft outer skin of the vessel wall.
