Abstract

The invention relates to the arrangement of rolling rings on a metal barrel, especially a beer barrel made of stainless steel, at least two rolling rings (6) being provided on a cylindrical wall (1) of the barrel, each rolling ring having a flat outer face (7) on which the barrel can roll while the side walls (8) are also flat and can be gripped with a lifting fork. In order to obtain a permanently firm connection between the rolling rings (6) and the barrel wall (1) even in the case of rough treatment, an endless annular hollow section is placed around the barrel wall (1) and the barrel wall is cold-formed in the contact zone in such a way that the section is definitely clamped. During this process, the adjoining wall part of this section can simultaneously be deformed as well while, if a suitable outer die is used, the outer wall parts of this section can likewise be deformed in order thereby to form the flat parts (7, 8) of the rolling ring. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum mit Rollreifen. Versehen eines Fasses aus Metall, und insbesondere aus rostfreiem Stahl.The invention relates to a method for using roller tires. Providing a barrel made of metal, and especially stainless steel.

Solche Fässer bestehen meistens aus einer vornehmlich zylindrischen Seitenwand, die mittels konvexer Wndwände abgeschlossen worden ist, um welche Seitenwand herum zwei oder mehrere Rollreifen angeordnet sind. Diese Rollreifen haben meistens eine flache Aussenfläche, auf welcher das Fass rollen kann, während die Seitenwände dazu bestimmt sindm mit einem Hebewerkzeug, z.B. einer Gabel, in Eingriff gebracht zu werden. Diese Rollreifen werden dabei mittels zwei auf beiden Seiten liegenden Schweissverbindungen mit der Seitenwand verbunden.Such drums usually consist of a predominantly cylindrical side wall, which has been closed off by means of convex wall walls, around which side wall two or more roller tires are arranged. These roller tires usually have a flat outer surface on which the barrel can roll, while the side walls are designed for this with a lifting tool, e.g. a fork to be engaged. These roller tires are connected to the side wall by means of two welded connections on both sides.

Ein wichtiger Nachteil solcher Rollreifen ist, dass die Schweissverbindungen nicht genügend fest sind, und deshalb bei der rohen Behandlung, welcher solche Fässer öfters ausgesetzt sind, zerbrichen werden können, so dass dann die Rollreifen sich allmählich lösen, und sich auf die Dauer ganz trennen werden.An important disadvantage of such roller tires is that the welded connections are not sufficiently strong, and can therefore be broken during the rough treatment to which such barrels are often exposed, so that the roller tires then gradually loosen and will separate completely in the long run .

Die Erfindung bezweckt einen Rollreifen für ein solches Fass zu beschaffen, welcher diesen Nachteil nicht besitzt.The invention aims to provide a roller tire for such a barrel, which does not have this disadvantage.

Dazu wird das erfindungsgemässe Verfahren zum Anordnen eines Rollreifens an einem Metallfass dadurch gekennzeichnet, dass ein ringförmig geschlossener Rollereifen mit Rinnen- oder Röhrenprofil um das Fass herumgelegt wird, und dass danach die Fasswand auswärts kalt verformt wird um dadurch den Rollreifen fastzuklemmen. Diese Verformung ist dabei vorzugsweise derartig, dass die Wand im dortigen Bereich der Form des Reifenprofils angepasst wird, so dass mittels einer diese Profilform folgende Wand-form eine optimale Festklemmung erhalten wird.For this purpose, the method according to the invention for arranging a roller tire on a metal barrel is characterized in that a ring-shaped closed roller tire with a trough or tubular profile is placed around the barrel, and that the barrel wall is then cold-deformed outwards, thereby almost clamping the roller tire. This deformation is preferably such that the wall in the area there is adapted to the shape of the tire profile, so that an optimal clamping is obtained by means of a wall shape following this profile shape.

Vorzugsweise wird dabei von einem aus einer Röhre gebildeten ringförmigen Reifen ausgegangen, welcher beim Verformen der Fasswand in einer derartig gestalteten äussercn Matrize festgehalten wird, dass auch diese Röhre kalt verformt wird, z.B. derart, dass wenigstens eine als Lauffläche dienende flache Aussenflaäche erhalten wird, während vorzugsweise auch die Querwände mehr oder weniger flach gemacht werden, so dass eine etwa ungefähr rechteckige oder quadratische Durchschnittsform erhalten wird.Preferably, it is assumed that an annular tire is formed from a tube, which is held in place when the barrel wall is deformed in such an outer die that this tube is also cold-deformed, for example in such a way that at least one is used as a tread serving flat outer surface is obtained, while preferably also the transverse walls are made more or less flat, so that an approximately rectangular or square average shape is obtained.

Die Fasswand wird mittels einer auswärts zu pressenden Innenmatrize nach aussen gepresst, welche Matrize vorzugsweise derart gestaltet ist, dass der Fasswand eine einigermassen wellenförmige Verformung erteilt wird, welche dem Rollenprofil angepasst ist, und wenigstens dessen Randbereiche einigermassen umgreifen kann. Bei gleichzeitiger Verformung der Wand und eines röhrenförmigen Rollreifens werden deren aneinanderschliessenden Teile gemeinsam und gleichförmig verformt.The barrel wall is pressed outwards by means of an inner die to be pressed outward, which die is preferably designed in such a way that the barrel wall is given a somewhat undulating deformation which is adapted to the roller profile and can at least encompass its edge regions to some extent. If the wall and a tubular roller tire are deformed at the same time, the parts that join together are deformed together and uniformly.

In dieser Weise wird eine gut passende und einer rohen Behandlung widerstehende Verbindung zwischen einem Rollreifen und ciner Fasswand erhalten, wobei ein besonderer Vorteil der Kaltverformung ist, dass dadurch das Wand- und ggf. Röhrenmaterial verfestigt wird, was zur Festigkeit der Verbindung beiträgt.In this way, a well-fitting and raw treatment-resistant connection between a roller tire and a barrel wall is obtained, a particular advantage of the cold deformation being that it solidifies the wall and possibly tube material, which contributes to the strength of the connection.

Die Erfindung bezieht sich weiterhin auf ein Fass, welches mittels dieses Verfahrens mit einem Rollreifen versehen ist.The invention further relates to a barrel which is provided with a roller tire by means of this method.

Die Erfindung wird im Untenstehenden näher an Hand einer Zeichnung erläutert; darin zeigt:

  • Fig. 1 einen Querschnitt durch einem Fass mit in erfindungsgemässer Weise angeordneten Rollreifen; und
  • Fig. 2 Schnitte im grösseren Masstab des Teiles II der Fig. 1 mit zwei verschiedenen Rollreifenprofilen.
The invention is explained in more detail below with reference to a drawing; therein shows:
  • 1 shows a cross section through a barrel with roller tires arranged in the manner according to the invention; and
  • Fig. 2 sections on a larger scale of part II of Fig. 1 with two different roller tire profiles.

In Fig. 1 ist ein Metallfass geläufiger Form, das insbesondere aus Rostfreiem Stahl hergestellt ist, in Querschnitt dargestellt. Dieses Fass besteht in der Hauptsache aus einer zylindrischen Seitenwand 1 mit darauf befestigten konvexen Endwänden 2. Zum Schutz dieser Endwände sind Ansätze 3 mit umgebördlter Endrand 4 in der Verlängerung der Seitenwand 1 angeordnet, wobei das Fass auf diesen Rändern 4 abgestellt werden kann. Ein in der Mitte einer Endwand vorgesehenes Zapfenloch 5 wird dann ebenfalls gegen Schädigung geschützt.In Fig. 1, a metal barrel of common shape, which is made in particular of stainless steel, is shown in cross section. This barrel mainly consists of a cylindrical side wall 1 with convex end walls 2 fastened thereon. To protect these end walls, lugs 3 with a flanged end edge 4 are arranged in the extension of the side wall 1, the barrel being able to be placed on these edges 4. A pin hole 5 provided in the middle of an end wall is then also protected against damage.

Um die Seitenwand herum sind zwei Rollreifen 6 mit flacher Aussenfläche 7 und flachen Seitenwänden 8 vorgesehen. Die Oberfläche 7 dient dabei als Lauffläche beim Rollen des Fasses, während ein Hebewerkzeug, z.B. eine Hubgabel, mit einer Seitenwind 8 in Eingriff gebracht werden kann.Around the side wall, two roller tires 6 with a flat outer surface 7 and flat side walls 8 are provided. The surface 7 serves as a tread when rolling the barrel, while a lifting tool, e.g. a lifting fork with a cross wind 8 can be brought into engagement.

Fig. 2 zeigt zwei Ausführungen von Rollreifen, die beide, ausgehend von einem röhrenförmigen Profil, erhalten worden sind, von welchem Profil erst ein geschlossener Ring gebildet wird, welcher mit einigem Spiel um die Wand 1 passt. Diese Rohre wird dann an der Aussenseite in einer nicht dargestellten Matrize eingeschlossen, und danach wird die Innenwand mittels einer ausdehnbaren Matrize auswärts verformt. Die Innenwand 9-der Röhre erhält dann die gleiche Form-wie der anschliessende Teil der Wand 1, so dass dann eine formschlüssige Verbindung der beiden Wände erha;ten wird, welche jede Verschiebung des Rollreifens in bezug auf die Fasswand entgegenwirkt.Fig. 2 shows two versions of roller tires, both of which have been obtained from a tubular profile, of which profile a closed ring is first formed, which fits around the wall 1 with some play. These pipes are then not shown on the outside in one provided die, and then the inner wall is deformed outwards by means of an expandable die. The inner wall 9 of the tube then has the same shape as the adjoining part of the wall 1, so that a positive connection between the two walls is then obtained, which counteracts any displacement of the roller tire with respect to the barrel wall.

In den beiden Fällen gemäss Fig. 2 ist von einer normalen Röhre mit rundem Querschnitt aus Eisen oder rostfreiem Stahl ausgegangen wird.'Durch Benutzung einer festen Aussenmatrize mit quadratischem Querschnitt sind die geraden Wände 7 und 8 gebildet worden. Im Fall der Fig, 2 A wurden mit einer Innenmatrize gearbeitet, welche eine Krümmung hat, welche derjenigen der Ursprüngsröhre einigermassen entspricht während im Fall der Fig. 8B eine Matrize mit wellenförmiger Krümmung benutzt wurde, welche in der Röhre eine einwärtse Sicke gebildet hat. Die Verbindung ist im letzteren Fall selbstverständlich besser als im ersteren.In the two cases according to FIG. 2, a normal tube with a round cross section made of iron or stainless steel is assumed. The straight walls 7 and 8 were formed by using a fixed outer matrix with a square cross section. In the case of FIG. 2A, an inner die was used which has a curvature which corresponds somewhat to that of the original tube, while in the case of FIG. 8B a die with a wavy curvature was used which formed an inward bead in the tube. The connection is of course better in the latter case than in the former.

Durch diese Verformung der Wand und der Röhre wird in beiden eine Verfestigung herbeigeführt, welch zur Festigkeit der Verbindung beiträgt, da dadurch Verformung unter Belastungen während der Benutzung besser vermieden werden kann.This deformation of the wall and of the tube brings about a consolidation in both, which contributes to the strength of the connection, since deformation under loads during use can thereby be avoided better.

Es ist jedoch auch möglich, von anders ausgangsprofilen auszugehen, z.B. von Profilen mit U-förmigen Querschnitt, wobei dann die Öffnung auf die Fasswand gerichtet ist, und diese Wand derart verformt wird, dass die Endränder des Profiles in der Wandverformung eingeklemmt werden. Die dargestellten Profile werden jedoch bevorzugt, da durch die WandberÜhrung eine bessere Verbindung erhalten wird. Darüberhinaus lassen Röhren sich leichter in Kreisform biegen.However, it is also possible to start from different starting profiles, e.g. of profiles with a U-shaped cross-section, the opening then facing the barrel wall, and this wall being deformed in such a way that the end edges of the profile are clamped in the wall deformation. The profiles shown are preferred, however, because a better connection is obtained by touching the wall. In addition, tubes are easier to bend in a circular shape.
