Description

Verfahren zur Herstellung von 1VIesserschalen und ähnlichen plattenförmigen Gegenständen aus mehreren durch dünne Metallstreifen voneinander getrennten Teilen aus plastischen = Massen Die Erfindung bezieht sich auf ein Ver- fahren zur HersteUung von Messexschalen'und ähnlichen. plattenförmigen Gegenständen aus- mehreren durch dünne Metalistreifen vonein- ander getrennten Teilen aus plastischen Mas- sen und bezweckt, die bisher umständlich durch Vernietung bewerkstdUgte Verbindung dieser Metallstreifen mit ,einer gleichveidg auch die aus plastischer Masse hergestellten- Teile tragenden Platine in einfachster Weise zu .ersetzen. Hierzu werden .gemäß der Erfindung in Rillen einer Preßform Metallstreifen einge- setzt und die dadurch in d;er Preßform ge-bl- d.eten Abtellungen mit plastischen Massen ge- füllt; auf diese wird ein rahmenartiges, mit seinen Längsteilen. in Randkerhen der Ma- tallstreifen passendes Blechstück aufgel%?t,und das Ganze gepreßt, worauf die über .den Um- riß des FormJimgs vorstehenden Teile der Metaustreifen entfernt werden. Die Mittel, die zu diesem Verfahren b:ei;- spie1swepse verwendet werden, sind in der Zeiclxnung in den Abb. 1, 2 und 3 im Grund- riß, im. Schnitt und in Septenausicht darge,- steU't; Abb. ¢ zeigt .die Draufsicht des sich beirr Pressen ergebenden rohen Werkstückes, Abb._5 .einen Schnitt nach der Linie x-x aus Abb.4 und Abb.6 eine Draufsicht des zuge- richteten fgen Werkstückes. Die zur Trennung der aus plastischen Mas- sen bestehenden Teile 10, 11, 12 dienenden Metallstreifen 13 werden in Rillen 14 der Preßfonn15 ,eingesetzt. Die dadurch in der Preßform gebildeten Abteilungen werden mit plastischen Massen ,gefüllt und dvese mixt einem rahlnenartägen Blechstück 16 bedeckt und dass Ganze gepreßt. Die Blechstücke 16 dienen ,als Verank-run.- gen zwischen den Teilen Io, 11, 12. Die LängsteRRe des rahmenargen Blechstückes 16 liegen in entsprechenden Randkerben der Me- tallstreifen 13 (Abb. 3), deren an der Ober- sexte des Formlings liegender Rand Riffeluuz- gen 17 hat. Diese Rifeh ung gen liegen einer- seits mit ihrer Außend,äche in der plastischen Masse des ,einen TeÄlers,: anderseits erbalten sie die plastische Masse des benachbarten Teiles eingepreßt, so, däß ein fester Zusam- menhelt der Teile gesichert ist. Nach erfolgter Pressung werden die über den Umfang des Earmlings vorstehenden Teile der Metallstreifen (Abb. 4, 5), z. B. durch Schleifen, entfernt, sgu daß das fertige Werk- stück sich mit der gewünschten Oberflächen- ausstattung Bahne jede Nigetung ergibt (Abb. 6). Process for the production of 1VIesserschale and similar plate-shaped objects from several parts separated from one another by thin metal strips made of plastic masses The invention relates to a drive to the manufacture of Messex shells and similar. plate-shaped objects several by thin metal strips from one other separate parts made of plastic mass sen and aims that hitherto cumbersome connection made by riveting this metal strip with, one identical also those made from plastic mass Parts-bearing board in the simplest way to replace. For this purpose, according to the invention in Grooves of a compression mold metal strips sets and thereby in the press mold d. compartments with plastic masses fills; on this is a frame-like, with its long parts. in Randkerhen the Ma- vertical strips matching piece of sheet metal dissolved%? t, and pressed the whole thing, whereupon the tore the FormJimgs protruding parts of the Meta strips are removed. The means involved in this procedure b: ei; - spie1swepse are used in the Drawing in Figs. 1, 2 and 3 in the basic tore, im. Cut and shown in septa view, steU't; Fig. ¢ shows the top view of the when pressing the resulting raw workpiece, Fig._5. A section along line xx Fig.4 and Fig.6 a top view of the set up the workpiece. The one used to separate the plastic mass sen existing parts 10, 11, 12 serving Metal strips 13 are in grooves 14 of the Pressfonn15, used. The result in the Divisions formed by the die are made with plastic masses, filled and dvese mixes a rahlnenartägen sheet metal piece 16 covered and pressed the whole thing. The sheet metal pieces 16 serve as an anchoring run. gen between parts Io, 11, 12. The Longest of the framed sheet metal piece 16 lie in the corresponding marginal notches of the tall strips 13 (Fig. 3), the top of which sixth of the molding lying edge Riffeluuz- gen 17 has. These regulations are due to one on the one hand with its exterior, surface in the plastic Mass of the, one teller,: inherited on the other hand they the plastic mass of the neighboring Pressed in, so that a solid assembly the parts are secured. After pressing, the over parts protruding the circumference of the earling the metal strip (Fig. 4, 5), e.g. B. by Grinding, removed, so that the finished work piece with the desired surface equipment track every nigetung results (Fig. 6).
