Description

Stanzwerkzeug zum Herstellen von Kautschukhohlkörpern, insbesondere Fußballblasen Die Erfindung bezieht sich auf ein Stanzwerkzeug zum Herstellen von Kautschukhohlkörpern, das sich von den bekannten, dem gleichen Zwedli.dienenden Werkzeugen durch seine besonders einfache wie zweckmäßige Bauform und günstige Arbeitsweise unterscheidet.Stamping tool for producing hollow rubber bodies, in particular Football bubbles The invention relates to a punching tool for making Hollow rubber bodies, which differ from the well-known, the same Zwedli.dienenden Tools thanks to its particularly simple and practical design and convenient mode of operation differs.

Die bisher gebräuchlichen Stanzwerkzeuge bestehen aus einer oberen und unteren Preßplatte und haben Stanz- und Schweißkanten, die durch Ausfräsen 0. dgl. kostspielige Arbeitsverfahren aus den Preßfiächen der beiden Platten gestaltet werden. The previously used punching tools consist of an upper one and lower press plate and have punched and welded edges, which by milling out 0. Like. Expensive working method designed from the press surfaces of the two plates will.

Als Ersatz für diese kqstspieligen Einzichtungen wurden Stanzwerkzeuge mit glatten Preßfiächen entwIckelt, die, um eine Schweißstanzung zu erzielen, mit einem in sich geschlossenen Stanzkörper aus Draht zusammenarbeiten, der von Hand aus zwischen die Preßplatten eingebracht wird. Derartige Stanzwerkzeuge verzögern aber die Herstellung von Kautschukhohlkörpern, da der Stanzkörper nach jeder durchgeführten Stanzung aufs neue mit den zu bearbeitenden Kautschukbjättern zwischen die Preßplatten ge. bracht werden muß. tim dieses Stanzwerkzeug für die verschiedensten Verwendungszwecke handlicher zu gestalten, wurde bei dem Stanzwerkzeug gemäß der Erfindung die Preßplatte mit federnden Stanzdrihten verbunden, die im Stanzbereich einen bestimmten Abstand von der Preßplattenfläche haben, um die zu stanzenden Kautschakblätter unterhalb des Stanzkörpers hindurchführen zu können. Für die besondere Verwendung dieses Werkzeuges zum Herstellen von Fußballblasen ist die Preßplatte mit mehreren, mindestens zwei Stanzdrähten verbunden. Die Ausführungsformen der Stanzwerkzeuge gemäß. der Erfindung gestatten sowohl eine Einzelstanzung als auch einen ununterbrochenen Stanzbetrieb von mit diesen Stanzwerkzeugen versehenen Preßeinrichtungen, wobei im letzteren Falle die unvulkanisierte Kautschukbahn fortlaufend durch das Stanzwerkzeug hindurchgeführt wird. As a substitute for these kqstspieligen fittings were punching tools developed with smooth press surfaces, which, in order to achieve a weld punch, with work together with a self-contained punched body made of wire, which is done by hand is introduced from between the press plates. Delay such punching tools but the production of hollow rubber bodies, since the punched body is carried out after each Stamping again with the rubber sheets to be processed between the press plates ge. must be brought. tim this punching tool for a wide variety of purposes to make more manageable, was the press plate in the punching tool according to the invention connected with resilient punched wires, which are a certain distance in the punched area from the press plate surface to the rubber sheets to be punched below to be able to pass through the punched body. For the special use of this tool for the production of football bubbles is the press plate with several, at least two Stamped wires connected. The embodiments of the punching tools according to. the invention allow both single punching and uninterrupted punching operations of with these Stamping tools provided pressing devices, wherein in the latter case the unvulcanized rubber sheet continuously through the punching tool is passed through.

In der Zeichnung ist ein Stanzwerkzeug -gemäß der Erfindung, wie es beispielsweise für die Herstellung von Fußballblasen zur Verwendung gelangt, im Aufriß in Abb. I und Grundriß in Abb. 2 dargestellt. In the drawing is a punching tool according to the invention, such as it is used, for example, for the production of football bubbles, shown in elevation in Fig. I and in plan in Fig. 2.

In diesen Abbildungen des Stanzwerkzeuges bezeichnet I die Preßplatte und 2 die Stanzdrähte, die zur Pneßplattenfäche 3 im Abstand x angeordnet sind, der durch Druck aufgehoben wird und beim Verschwinden des Druckes wieder erscheint. Der Abstandx beträgt in allen Teilen des formgebenden Stanzdrahtes etwas mehr als die Stärke der doppelt oder mehrfach aufeinandergelegten zu stanzenden Kautschukblätter. Die auf der Preßplatte I befestigten Stanzdrähte 2 sind an ihren Enden 4 durch Schraubensicherungen 5 0. dgl.. mit der Preßplatte verbunden. Die Stanzdrähte haben in ihren Teilen 6, welche die Umrißformen der Fußballblase ausstanzen, die volle Drahtstärke, während ihre nach außen geführten geraden Arme 7 eine geringere Stärke haben, damit das seitliche Uber-'schußmatenal der Kautschukblätter- nicht durchgestanzt wird. 8 ist eine in der Form mit der Preßunterplatte 1 übereinstimmende Preßoberplatte, die gemeinsam bewirken, daß die Stanzdrähte 2 die Kautschukblätter 99 in der Außenform des Hohlkörpers verbinden und vom übrigen Material abtrennen. Die -Kautschukbiätter g bilden in der gezeichneten Anordnung einen Streifenstapel mit gefalteten Blättern IO. In these figures of the punching tool, I denotes the press plate and 2 the punched wires, which are arranged at a distance x from the pneumatic plate surface 3, which is canceled by pressure and reappears when the pressure disappears. The distance x amounts to a little more than in all parts of the shaping punch wire the thickness of the rubber sheets to be punched twice or several times on top of one another. The punched wires 2 attached to the press plate I are secured at their ends 4 by screw locks 5 0. the like .. connected to the press plate. The punched wires have 6 in their parts, which punch out the outline of the football bubble, the full wire thickness, while their outwardly directed straight arms 7 have a smaller thickness, so that the Lateral excess material of the rubber sheets is not punched through. 8 is one in the shape of the lower press plate 1 matching upper press plate, the together cause the punch wires 2 to form the rubber sheets 99 in the outer shape of the hollow body and separate from the rest of the material. The rubber sheets In the arrangement shown, g form a stack of strips with folded sheets IO.

Beim Herstellen der Fußballblasen oder dergleichen Hohlkörper greifen die Stanzdrähte 2 in die von den beiden gefalteten BlätternIo gebildeten Taschen ein und führen den Staplel während des Fortbemregens. When making the soccer balls or the like, grab hollow bodies the punched wires 2 in the pockets formed by the two folded sheetsIo and guide the stack while driving.

Werden die beiden Preßplatten i, 8 bis annähernd in der Stärke der Stanzdrähte zusammengeführt, so tritt durch Einpressen der Stanzdrähte in den unvuilnisierten Kautschuk ein Verschweißen und Durchtrennen der oberhalb und unterhalb der Stanzdrähte befindiichen Kautschukblätter ein, durch welchen Vorgang die hohle Ballseele gebildet wird. If the two press plates i, 8 to approximately the strength of the Punched wires are brought together, so occurs by pressing the punched wires into the unvarnished Rubber welding and cutting the above and below the punched wires rubber sheets, through which process the hollow ball core is formed will.

Vorteilhaft schließen sich die beiden Preßplatten in solchen Zeitabständen, daß die Bedienung gerade genug Zeit hat, um den bereits gestanzten Streifenstapel um die Länge des Stanzstückes herauszuziehen. Die ausgestanzte unvulkanisierte Ballseele, die noch mit dem Stanzabfall durch dünne Lamellen verbunden ist, wird herausgelöst und der Weiterverarbeitung zugeführt. The two press plates advantageously close at such time intervals that that the operator has just enough time to remove the already punched stack of strips to pull out the length of the die cut. The punched unvulcanized ball soul, which is still connected to the punching waste by thin lamellas is removed and fed to further processing.

Die Stanzdrähte können je nach Erfordernis ganz oder teilweise an der Preßunter- oder -oberplatte befestigt sein. Sind die Stanzdrähte zu einer in sich geschlossenen Form vereinigt, so ist dieser Stanzkörper für die Reihenfertigung an den Stirnseiten, die quer zur Fortschaltrichtung der Kautschukblätter liegen, schwächer auszubilden als die in der Längsrichtung liegenden Drahtstanzteile. The punched wires can be wholly or partially depending on requirements be attached to the press lower or upper plate. Are the punch wires to an in united in a closed form, this punched body is suitable for serial production on the end faces, which are perpendicular to the direction of progression of the rubber sheets, to be weaker than the punched wire parts lying in the longitudinal direction.
