Description
Verfahren zur Herstellung einer geschweißten Rundnaht für Blechbehälter, insbesondere Konservendosen Gegenstand der Erfindung ist ein Verfahren zur Herstellung seiner geschweißten Rundnaht für Blechgefäße, insbesondere Konservendosen. Die nach dem neuen Verfahren hergestellten Blechgefäße weisen einen außerordentlich versteiften Bodenrand (oder Deckelrand) und eine gute Einspannung des-Bodens (oder Deckels) zwecks guter Durchfederungsmöglichkeit bei der Sterilisation auf, ohne daß im Innern des Gefäßes scharfe Kanten entstehen. Bei der Eizeugung der neuen Rundnaht wird der Boden (oder Deckel) ohne weiteres in einer Zentrierlage festgehalten, so daß ein sicheres Verschweißen leicht möglich ist.Process for the production of a welded round seam for sheet metal containers, in particular food cans The invention relates to a method of production its welded round seam for metal containers, especially food cans. The after The sheet metal vessels produced using the new process are extremely stiffened Bottom edge (or lid edge) and a good restraint of the bottom (or lid) for the purpose of good deflection during sterilization without being inside the vessel has sharp edges. When the new circumferential seam is opened the bottom (or cover) readily held in a centering position so that safe welding is easily possible.
Das neue Verfahren besteht darin, daß man i. an dem Gefäßrumpf nahe seinem zu verschließenden Ende eine nach innen vorspringende Sicke anordnet, a. .auf die Sicke einen Flachboden (oder -deckel), gegebenenfalls mit leicht angekipptem Rand auflegt, 3. den über den Boden (oder Deckel) vorstehenden Rand des Rumpfes nach innen umlegt und ihn q.. mit dem Boden (oder Deckel) durch elektrische Widerstandsschweißung verschweißt.The new method consists in that i. close to the vessel body arranges an inwardly projecting bead at its end to be closed, a. .A flat base (or cover) on the bead, if necessary with a slightly tilted The edge of the fuselage, 3. the edge of the fuselage protruding from the base (or cover) folds inwards and q .. with the bottom (or cover) by electrical resistance welding welded.
Es ist zweckmäßig, den Rand des Blechbodens (oder -deckels) vor dem Auflegen auf die Sicke des Dosenrumpfes an die Außenfläche des Bodens bzw. Deckels zurückzufalten.It is useful to put the edge of the sheet metal bottom (or cover) in front of the Place on the bead of the can body on the outer surface of the bottom or lid fold back.
Fig. i der Zeichnung zeigt als Beispiel im Schnitt den Teil. eines Rumpfes a, der in der Nähe seiner zu verschießenden Boden- (oder Deckel-) öffnung eine nach innen vorspringende Sicke b aufweist. Auf diese Sicke ist ein Flachboden c (oder -deckel) mit leicht angekipptem Rand aufgelegt. Das über den Boden (oder Deckel) vorstehende Ende d des Rumpfes., wird hach innen umgelegt und in dieser in Fig. a gezeichneten Stellung mittels Elektroden verschweißt. Der eingesetzte Boden e (oder Deckel) kann gemäß Fig. 3 auch mit einem umgelegten Rand e versehen sein, der nach dem Einlegen des Bodens c (oder Deckels) auf die Sicke b des Rumpfesa mit dem Randd dieses Rumpfes in der in Fig. 4 gezeigten umgelegten Stellung zu verschweißen ist. Die mit dem -nach innen umgelegten Rande versehenen Bödenre (oder Deckel) weisen den großen Vorteil auf, daß sie wegen ihres. doppelten Randes stapelfähig sind und infolgedessen bei maschineller Herstellung der Dosen keinerlei Schwierigkeiten, die zu Ausschuß führen können, bieten.Fig. I of the drawing shows as an example in section the part. one The fuselage a, which is in the vicinity of its bottom (or cover) opening to be closed has an inwardly projecting bead b. There is a flat bottom on this bead c (or cover) placed with the edge slightly tilted. That over the ground (or Lid) protruding end d of the fuselage., Is turned inside and in this Welded position shown in Fig. a by means of electrodes. The deployed Bottom e (or cover) can also be provided with a folded edge e according to FIG. 3 after inserting the bottom c (or cover) onto the bead b of the fuselage a with the edge of this fuselage in the folded-over position shown in FIG to is welded. The floor reeds (or Lid) have the great advantage that they because of their. double edge stackable and consequently there are no difficulties in the machine production of the cans, that can lead to rejects.
Auch kann der Boden c (oder Deckel) gemäß Big. 5 mit einem hochgestellten Rand/ versehen, auf die nach innen vorspringende j Sicke b des Rumpfes a aufgelegt, dann der Randd des Rumpfes zusammen mit dem Rand j des Bodens (oder Deckels) nach innen umgelegt und in dieser in Fig.6 gezeigten Lage die elektrische Widerstandsschweißung durchgeführt werden.The bottom c (or cover) can also be made according to Big. 5 with a superscript Edge / provided, placed on the inwardly protruding j bead b of the fuselage a, then the edge d of the body together with the edge j of the bottom (or lid) turned inside and in this position shown in Fig. 6 the electrical resistance welding be performed.
Die Anwendung von Sitzen zum Bestlegen der Lage des Bodens ist an sich bekannt. Ebenso ist es bekannt, den Bodenrand nach dem Schweißen nach innen umzulegen.The use of seats to determine the location of the floor is on known. It is also known to turn the bottom edge inwards after welding to kill.
Gegenstand der Erfindung ist demnach die amt-endung der vier Verfahrensschritte in der angegebenen Reihenfolge.The subject of the invention is therefore the end of the four process steps in the order given.
