Die Vorrichtung zur Fertigung von Kunststoffbügelen den aus Acetat nach dem erfindungsgemäßen Verfahren kennzeichnet sich dadurch, daß das Doppel gesenk aus einem oder zwei gegenläufigen Stempeln be steht, in deren Längsrichtung die obere bzw. untere Wölbform eines ungebogenen Bügelendes eingebracht ist, von der über eine Rundkante im spitzen Winkel zur Werkzeugquerschnitts-Symmetrieachse eine Erweiterung zum Abfließen des Preßmaterials auch beim Einbringen des Steckkanals in die Ränder der Grundplatine vorgesehen ist.The device for the production of plastic brackets from acetate according to the inventive method is characterized in that the double die from one or two counter-rotating dies stands in the longitudinal direction of the upper or lower An arched bow end is introduced, from over a round edge at an acute angle to Tool cross-section symmetry axis an extension to drain the press material even when inserting of the plug-in channel provided in the edges of the motherboard is.
In der Zeichnung ist die Verfahrensweise zur erfindungs gemäßen Fertigung von Kunststoffbügelenden und eine Vorrichtung hierzu sowie ein fertiges Bügelende dar gestellt und zwar zeigen: In the drawing, the procedure for fiction according production of plastic temple ends and a Device for this as well as a finished temple end and show:
Fig. 1 bis 3 die Seitenansicht einer Grundplatine in kompakter, ein-, zwei- oder dreischichti ger Form, Figs. 1 to 3 is a side view of a motherboard in a compact, mono-, di- or dreischichti ger shape,
Fig. 4 die Draufsicht hier bei getigerter Deckschicht der Grundplatine, Fig. 4 is a plan view here at tabby top layer of the base board,
Fig. 5 den Querschnitt durch das Doppelgesenk als gegeneinanderlaufende Stempel, Fig. 5 shows the cross section through the Doppelgesenk as contra-punches,
Fig. 6 und 7 die Draufsicht und den Querschnitt auf die Grundplatine nach der Prägung bei wieder ausgezogener Nadel, FIGS. 6 and 7, the top view and the cross-section on the motherboard after the embossing in the needle-extended again,
Fig. 8 und 9 die Draufsicht auf das ausgefräste und polierte Brillenbügelende vor und nach dem Ein bringen des Metallbügelendes. Fig. 8 and 9, the top view of the milled and polished temple end before and after the A bring the metal strap end.
Aus Fig. 1 bis 3 sind in Seitenansicht eine Grundplati ne 1 in kompakter Form in Fig. 2 mit Deckschicht 2 und in Fig. 3 mit beidseitiger Deckschicht 3 als Ausgangs material dargestellt, während Fig. 4 die Draufsicht auf eine Grundplatine mit getigerter Deckschicht 4 zeigt. Solche Grundplatinen 1 werden in erwärmter Form in ein Doppelgesenk eingelegt.From Fig. 1 to 3, a Grundplati are in side view ne 1 in a compact form in FIG. 2 with the covering layer 2 and in Fig. 3 with double-sided coating layer 3 as the starting material, while Fig. 4 shows the top view of a motherboard with tabby cover layer 4 shows. Such motherboards 1 are inserted in a heated mold in a double die.
In Fig. 5 ist sodann der Querschnitt durch das Doppel gesenk mit zwei gegeneinanderlaufenden Stempeln 5 dar gestellt, in deren Längsrichtung die obere bzw. untere Wölbform 6 eines ungebogenen Bügelendes eingebracht ist, von der (6) jeweils über eine Rundkante 7 im spitzen Winkel von 20° zur Werkzeugquerschnitts-Symmetrieachse A-A eine Erweiterung 8 zum Abfließen des Preßmaterials auch beim Einbringen des Steckkanals 9 in die Ränder 10 der Grundplatine 1 vorgesehen ist.In Fig. 5 then the cross section through the double die with two counter-running punches 5 is provided, in the longitudinal direction of which the upper or lower arch shape 6 of an unbent temple end is introduced, of which ( 6 ) each have a round edge 7 at an acute angle of 20 ° to the tool cross-section axis of symmetry AA, an extension 8 for draining the pressed material is also provided when inserting the plug-in channel 9 into the edges 10 of the motherboard 1 .
Im Doppelgesenk mit einem oder beiden gegenläufigen Stempeln 5 wird nach dem Einbringen der erwärmten Grundplatine 1 in kompakter, geschichteter und/oder getigerter od. dgl. Form beidseits als Vorprägung eine Rillung 11 in Form des ungebogenen Brillenbügelendes 12 und sodann eine erhitzte Nadel entspr. dem späteren Metallbügel 13 mit Ende 14 eingeschossen und damit der Steckkanal 9 im Doppelgesenk eingebracht. Beim Fertigprägen werden die Rillen 11 sodann vertieft und das überflüssige Deckmaterial läuft durch die Rundkan te 7 in den Randbereich 10, so daß die Fertigform des Bügelendes 12 nahezu erreicht ist. Nach Entnahme vom Doppelgesenk mit den beiden Stempeln 5 wird aus der Grundplatine 1 entlang der Rillung 11 das ungeboge ne Brillenbügelende 12 ausgefräst und nach dem Ein bringen des Metallbügel 13 mit Steckende 14 in die Endform 15 gebogen. Hierbei lassen sich neben runden Metallbügelenden auch eckige einbringen bei entspr. Querschnitt der eingeschossenen und wieder entnommenen Nadel; bei runden Metallbügelnenden wird in die Run dung eine Abflachung eingebracht, um eine Verdrehung des aufgesetzten Kunststoffbügelendes zu vermeiden.In the double die with one or both counter-rotating punches 5 , after the introduction of the heated base plate 1 in a compact, layered and / or tabby or the like form, a groove 11 in the form of the unbented temple end 12 and then a heated needle correspond to the embossing on both sides later metal bracket 13 shot at the end 14 and thus inserted the plug-in channel 9 in the double die. When finishing embossing, the grooves 11 are then deepened and the superfluous cover material runs through the Rundkan te 7 in the edge region 10 , so that the finished shape of the temple end 12 is almost reached. After removal of the double die with the two stamps 5 , the unbent ne temple end 12 is milled from the motherboard 1 along the groove 11 and after the metal bracket 13 with a plug end 14 is brought into the final shape 15 . In addition to round metal temple ends, angular ones can also be introduced with the corresponding cross-section of the inserted and removed needle; In the case of round metal temple ends, a flattening is made in the run, in order to avoid twisting of the attached plastic temple end.
