Description
Modellformkörper für die Blechverarbeitung Aus Polyacrylharzen, wie sie z. B. unter dem geschützten Namen Plexiglas bekannt sind, stellt man Stoffe aller Art mit Eigenschaften her, die sich bezüglich ihres Härtezustandes stufenmäßig voneinander unterscheiden, also vom plastischen bis zum festen Zustand mit erheblicher Härte. Man hat aus diesem Material bereits Klebeschichten hergestellt, die geeignet waren, Silicatglasschei-,ben miteinander zu verkleben, um auf diese Weise ein Sicherheitsglas herzustellen.Model moldings for sheet metal processing Made of polyacrylic resins such as she z. B. are known under the protected name Plexiglas, one makes fabrics of all kinds with properties that vary in terms of their hardness differ from each other, i.e. from the plastic to the solid state with considerable Hardness. Adhesive layers that are suitable have already been produced from this material were to glue together silicate glass panes to create a safety glass to manufacture.
Es wurde nun gefunden, daß weiche Polyacrylharze auch zu anderen Zwecken brauchbar sind, die mit einem Klebezweck nichts zu tun haben. Der Anmelder fand, daß dieses Material sehr gut zur Herstellung von Matrizen und Patrizen für Verformungsverfahren aller Art, insbesondere für die Blechverarbeitung, verwendbar ist Die Herstellung der Blöcke erfolgt in der in der Kunstharzverarbeitung üblichen Weise, indem z. B. It has now been found that soft polyacrylic resins also contribute to others Purposes are useful that have nothing to do with an adhesive purpose. The applicant found this material very good for making matrices and male molds for Deformation processes of all kinds, especially for sheet metal processing, can be used The blocks are manufactured in the usual way in synthetic resin processing Way, by z. B.
Filme oder Platten aus diesem Material bei 800 unter sehr hohem Druck zu dem Gebrauchszweck entsprechend geformten Blöcken verpreßt. werden. Ein so hergestellter erkalteter Block behält seine Form bei dem genannten Verarbeitungsverfahren bei; er muß allerdings, wenn bei dem Verarbeitungsverfahren Wärmeerscheinungen auftreten, gekühlt werden. Er hat aber den Vorteil, daß bei dem Erfordernis einer neuen Form das Material nicht als Abfall wertlos wird, sondern neu verformt und damit wieder benutzt werden kann. Diese Verformung erfolgt unter Erwärmung beispielsweise bei 800, worauf nach dem Erkalten ein genügend widerstandsfähiger Modellformkörper erhalten wird.Films or plates of this material at 800 under very high pressure pressed for the purpose of use appropriately shaped blocks. will. One made in this way cooled block retains its shape during the processing process mentioned; it must, however, if heat phenomena occur during the processing process, be cooled. But it has the advantage that when a new shape is required the material does not become worthless as waste, but is reshaped and thus again can be used. This deformation takes place with heating, for example at 800, whereupon a sufficiently resistant molded model body is obtained after cooling will.
Für die Herstellung der vorstehend beschriebenen.Modellformkörper lassen sich mit Vorteil die bei der Verarbeitung von Sicherheitsglas anfallenden Acrylharzabfälle verwerten. Aus diesen Abfallschichten lassen sich in der oben beschriebenen Weise, namlich durch Verpressen der Acrylharzschichten bei erhöhter Temperatur, z. B. von etwa 80°, unter sehr hohem Druck, beispielsweise 1000 und mehr Atmosphären, Blöcke herstellen, die als Modellformkörper verwendbar sind. For the production of the model moldings described above can advantageously be used for the processing of safety glass Recycle acrylic resin waste. Let out these layers of waste themselves in the manner described above, namely by pressing the acrylic resin layers at elevated temperature, e.g. B. of about 80 °, under very high pressure, for example 1000 and more atmospheres, producing blocks that can be used as model moldings are.
