KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es werden, besonders in der Zahntecbnik, Pressen benutzt, bei denen Bleche mittels Flüssigkeitsdruckes in die Matrize hineingepreßt werden, wobei eine Gummimembran die Abdichtung zwischen Flüssigkeit und Matrize bewirkt.There are, especially in the dental technology, used presses in which sheets by means of Liquid pressure are pressed into the die, with a rubber membrane creates a seal between the liquid and the die.
Diesen bekannten Vorrichtungen hafteten bisher solche Mängel an, daß sie nur vereinzelt zur Anwendung kamen. Vor allemThese known devices have so far suffered from such deficiencies that they only sporadically came into use. Above all
ίο machte die Abdichtung und die häufig erforderliche Auswechselung der Gummimembran Schwierigkeiten.ίο made the waterproofing and often required Replacement of the rubber membrane Difficulty.
Demgegenüber besteht die vorliegende neue Erfindung darin, daß die Gummimembran hinter einem vorspringenden Rande des Preßraumes liegt, gegen den sie durch eine Metallplatte angedrückt wird, so daß die 'Membran auch dann dichtet, wenn die Presse nicht unter Druck steht.In contrast, the present new invention is that the rubber membrane lies behind a protruding edge of the press space, against which it is protected by a metal plate is pressed so that the 'membrane also seals when the press is not under pressure.
In der beiliegenden Zeichnung ist ein Schnitt durch eine Presse mit der neuen Abdichtung, und zwar im Moment der Pressung, dargestellt.The accompanying drawing shows a section through a press with the new seal, at the moment of pressing.
Es ist α der aus Stahl bestehende Hauptpreßkörper. In diesen ist die sogen. Küvette b mit der Matrize c eingesetzt und wird durch den Verschluß d festgehalten. Der Preßdruck wird durch Eintreiben der Spindel e in den mit Flüssigkeit gefüllten Stiefel f erzeugt, der durch Löcher mit dem ebenfalls gefüllten Preßraum g verbunden ist. h ist die Gummimembran, welche den Flüssigkeitsdruck auf das Blechwerkstück η überträgt. Damit diese Membran - auch beim Herausnehmen der Küvette abdichtet und ihre Lage beibehält, wird sie durch eine besondere Metallplatte an einen überstehenden Rand des Preßkörpers angepreßt. Diese Platte besteht aus dem Mittelstück i und den aufgeschraubten Segmentstücken k, so daß sie also trotz des vorspringenden Dichtungsrandes geteilt in den Preßraum hineingebracht werden kann. Die Schraube I dient zum Anpressen der Platte z; sie ist durch das mit. Verschluß m versehene Loch zugänglich. It is α the main pressed body made of steel. In these is the so-called. The cuvette b with the die c is inserted and is held in place by the closure d . The pressing pressure is generated by driving the spindle e into the boot f , which is filled with liquid and which is connected through holes to the pressing space g, which is also filled. h is the rubber membrane which transfers the liquid pressure to the sheet metal workpiece η . So that this membrane - also seals when the cuvette is removed and maintains its position, it is pressed against a protruding edge of the pressed body by a special metal plate. This plate consists of the middle piece i and the screwed-on segment pieces k, so that it can be brought into the press chamber in parts despite the protruding sealing edge. The screw I is used to press the plate z; she is through that with. Closure m provided hole accessible.
Behufs Vornahme einer Pressung wird das annähernd richtig gebogene Blechstück mit Wachs auf die Matrize geheftet. Nach Einsetzen der Matrize wird der Verschluß eingeschraubt und der Preßkolben eingetrieben.In order to carry out a pressing, the approximately correctly bent piece of sheet metal is also included Wax attached to the die. After inserting the die, the lock is screwed in and the plunger driven in.
