Description
Die Erfindung betrifft eine Vorrichtung zum Kalibrieren von Wickelkartuschen, also Kartuschen, die durch Rollen eines trapezförmigen Bleches hergestellt werden.The invention relates to a device for calibrating winding cartridges, that is to say cartridges that can be made by rolling a trapezoidal sheet.
Das Kalibrieren solcher Kartuschen ist nicht einfach, da der Widerstand gegen die in radialer Ebene erfolgenden Drucke veränderlich ist. Bekannte KaIibriervorrichtungen haben sich deswegen nicht bewährt.Calibrating such cartridges is not easy because of the resistance to the radial plane printing is variable. Known calibration devices have therefore not proven themselves.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Kalibrieren von Wickelkartuschen zu schaffen, die allen Anforderungen gerecht wird.The invention is based on the object of a device for calibrating winding cartridges to create that meets all requirements.
Die Erfindung besteht darin, daß die Vorrichtung aus einem radial spreizbaren Dorn besteht, der aus einem Stapel von koaxialen Ringen aus verformbarem Stoff gebildet ist, deren Elastizität in dem Maße abnimmt, wie die Wandstärke der Kartuschenhülse abnimmt. Vorteilhaft besteht der elastische Dorn aus Gummi.The invention consists in that the device consists of a radially expandable mandrel, which consists of a stack of coaxial rings made of deformable material, the elasticity of which decreases as the how the wall thickness of the cartridge sleeve decreases. The elastic mandrel advantageously consists of Rubber.
Die Erfindung ist an Hand der Zeichnung erläutert. In dieser zeigt aoThe invention is explained with reference to the drawing. In this shows ao
Fig. 1 den Grundriß eines trapezförmigen Bleches ?ur Herstellung einer Wickelkartusche und1 shows the plan view of a trapezoidal sheet metal for the production of a winding cartridge and
Fig. 2 einen Längsschnitt durch eine auf einem Kalibrierdorn aufgespannte Wickelkartusche.2 shows a longitudinal section through a winding cartridge clamped on a calibration mandrel.
Wickelkartuschen werden bekanntlich durch Zusammenrollen eines trapezförmigen, in Fig. 1 dargestellten Bleches 1 hergestellt. Die Wandstärke solcher Kartuschen ist nicht gleichförmig. Ein Teil der Hülsenwand, insbesondere die Basis, hat dreifache Stärke, während der mittlere Teil nur zwei- und der Scheitel einfache Stärke aufweisen. Der Rand des Bleches 1, der nach dem Einrollen den anderen Blechrand überdeckt, ist vorher abgefast worden.As is known, winding cartridges are produced by rolling up a trapezoidal one shown in FIG Sheet 1 produced. The wall thickness of such cartridges is not uniform. A part the sleeve wall, especially the base, has three times the strength, while the middle part is only two and the parting is of simple thickness. The edge of the sheet 1, the other sheet edge after rolling covered, has been chamfered beforehand.
Zur Herstellung einer solchen Wickelkartusche verwendet man einen Dorn, der von Ringen 2 bis 6 gebildet
wird. Diese Ringe sind koaxial übereinandergestapelt, so daß ein zylindrischer Dorn, wie in Fig. 2
dargestellt, entsteht. Der von den Ringen 2 bis 6 gebildete Dorn wird von der Kartuscbemhülse 7 umfaßt,
über die eine Stahllehre 8 geschoben wird. Der Sternpel 9 einer Presse wird nun auf die Basis der Kartuschenhülse
7 aufgesetzt. Diese Basis ist nach oben gerichtet und hat, wie schon gesagt, dreifache Stärke.
Der Stempel 9 dient auch dazu, den Rand der Hülse 7 umzubiegen. Während dieses Vorgangs stützt sich der
Stempel 9 auf den Rand der Hülse und auf den Spreizdorn ab. Die Einwirkung auf die Hülse ist hier-Vorrichtung
zum Kalibrieren
von WickelkartuschenA mandrel formed by rings 2 to 6 is used to produce such a winding cartridge. These rings are stacked coaxially one on top of the other, so that a cylindrical mandrel, as shown in FIG. 2, is formed. The mandrel formed by the rings 2 to 6 is encompassed by the cartridge sleeve 7, over which a steel jig 8 is pushed. The star pel 9 of a press is now placed on the base of the cartridge sleeve 7. This base is directed upwards and, as already said, has three times the strength. The punch 9 also serves to bend the edge of the sleeve 7. During this process, the punch 9 is supported on the edge of the sleeve and on the expanding mandrel. The action on the sleeve is here a device for calibration
of wrapping cartridges

bei nicht gleichförmig. Die Ringe 2 bis 6 sind deshalb aus verformbarem Stoff, vorzugsweise Gummi, und so radial spreizbar. Ihre Elastizität nimmt in dem Maße ab wie die Wandstärke der Kartuschenhülse.at not uniform. The rings 2 to 6 are therefore made of deformable material, preferably rubber, and so radially expandable. Their elasticity decreases to the same extent as the wall thickness of the cartridge sleeve.
So ist der Ring 2 elastischer als der Ring 3, der elastischer ist als der Ring 4, der Ring 4 ist elastischer als der Ring 5, und dieser ist endlich elastischer als der Ring 6.So the ring 2 is more elastic than the ring 3, the is more elastic than the ring 4, the ring 4 is more elastic than the ring 5, and this is finitely more elastic than the ring 6.
Auf diese Weise erzielt man eine gleichmäßige und dauernde Verformung der Kartuschenhülse, die genau die Form der Lehre 8 annimmt, in die sie eingeschoben wurde.In this way, a uniform and permanent deformation of the cartridge sleeve is achieved, which is exactly takes the form of gauge 8 into which it was inserted.
