Vorrichtung zum Ziehen von luftdurchlässigen Folien und Platten mittels Preßluft oder VakuumDevice for drawing air-permeable foils and plates by means of compressed air or vacuum
Es handelt sich um eine Vorrichtung, um thermoplastische Folien und
Platten im Ziehverfahren zu verarbeiten, ohne daß diese 1uf^undupchlässig
sein müssen.
Derzeitiger Stand der Technik:It is a device to process thermoplastic foils and plates in the drawing process without these having to be unreliable .
Current state of the art:
Die zu verformende Folie wird in einen Spannrahmen ringsum eingespannt.
Dann wird die Folie zur Verformung vorbereitet, also z.t>. beheizt. Das
Formwerkzeug fährt in die Folie hinein und die Folie wird mit Vakuum und / oder Preßluft ar das Formwerkzeug gesaugt / gedruckt. Dazu ist es
notwendig, daß die Folie selbst luftundurchlässig ist, da sonst das verformende Medium (i.a. Luft) nicht wirksam werden kann.
Die Schwäche dieses Verfahrens liegt darin, daß perforierte, gelochte oder sonstwie durchlässige Folien nicht verarbeitet werden können.
Die Aufgabe stellt sich also wie folgt: man muß davon unabhängig sein,
ob die zu verarbeitenden Platten luftdurchlässig sind oder nichts Dazu
stellt sich die Forderung, die Vorrichtung auf bestehenden Formmaschinen
einzusetzen.
Arbeitsweise der Vorrichtung:The film to be deformed is clamped all around in a clamping frame. Then the film is prepared for deformation, so zt>. heated. The mold moves into the film and the film is sucked / printed with vacuum and / or compressed air ar the mold. For this it is necessary that the film itself is impermeable to air, otherwise the deforming medium (generally air) cannot take effect. The weakness of this method is that perforated, perforated or otherwise permeable foils cannot be processed. The task is thus as follows: one must be independent of whether the panels to be processed are air-permeable or nothing. In addition, the requirement arises to use the device on existing molding machines.
Operation of the device:
Auf dem Tisch (1) der Maschine liegt das Formwerkzeug (2), Die luftdurchlässige Folie (3) ist in einen Spannrahmen (4-) eingespannt. In den oberen Rahmen ist eine elastische Membrane (5) eingesetzt. Die Folie (3) wird von unten beheizt (6) bis sie plastifizierber ist. Die Heizung fährt zurück und das Formwerkzeug (2) in die Folie hinein und streckt dabei Folie (3) und Membrane (5) vor. Nun ist es möglich, die Luft aus dem Zwischenraum Folie-Form zu saugen. Schwere Folien können zusätzlich.On the table (1) of the machine lies the molding tool (2), which is permeable to air Foil (3) is clamped in a clamping frame (4-). An elastic membrane (5) is inserted into the upper frame. The foil (3) is heated from below (6) until it is plasticizable. The heating system moves back and the forming tool (2) into the film and stretches the film (3) and membrane (5) forwards. Now it is possible to get out of breath to suck the gap foil-form. Heavy foils can also be used.
