Stanze für dünne Bleche, wie Gaumenplatten u. dgl.
Die Erfindung bezieht sich auf Stanzen für dünne Bleche, wie Gaumenplatten u. dgl., und bezweckt, solchen Blechen in einem einzigen Arbeitsgange die gewünschte Form zu geben, ohne dass sich im Werkstücke Falten bilden. Diese Faltenbildung soll selbst dann nicht eintreten, wenn härtester Werkstoff verwendet wird, z. B. Stahl, insbesondere solcher Chrom-Nickelstahl, der gegen den Angriff von Säuren sehr widerstandsfähig ist.
Auf der Zeichnung ist ein zur Herstellung von Gaumenplatten bestimmtes Ausführungsbeispiel
EMI1.1
Werkstück und Gesenk bei der Stellung zu Beginn des Stanzvorganges, Fig. 2 einen entsprechenden Schnitt bei einer während des Stanzvorganges eintretenden Stellung und Fig. 3 einen entsprechenden Schnitt bei der Stellung nach Beendigung des Stanzvorganges.
A bezeichnet das Gesenk und B das das Werkstück bildende Blech. Der Stempel C besteht in seinem zur Anlage an dem Werkstücke bestimmten'Teile in bekannter Weise aus einem bildsamen Stoffe, z. B. Blei. Dieser Teil des Stempels C ist nun gemäss der Erfindung so ausgebildet, dass beim Arbeitsgange das Werkstück B an den hochstehenden Rändern a1 des Gesenkes möglichst frühzeitig zwischen Stempel und Gesenk festgeklemmt wird, wie insbesondere aus Fig. 2 ersichtlich ist.
Im Verlaufe des Stanzvorganges schmiegt sich der Stempel C infolge seiner Bildsamkeit der Form des Gesenkes mehr und mehr an (Fig. 2 und 3), während gleichzeitig die Mitte des Bleches B allmählich in die Gesenkhohlung hineingedrückt wird. Hiebei wird das Blech B an den hochstehenden Rändern a1 des Gesenkes A entsprechend dem steigenden Werkstoffbedarfe zwischen Gesenk und Stempel unter Überwindung der durch den Druck des Stempels erzeugten Festklemmung nach innen durchgezogen.
Gegenüber bekannten ähnlichen Einrichtungen wird durch das Festklemmen des Bleches B an den hochstehenden Rändern des formgebenden Gesenkes der Vorteil erreicht, dass das Stanzen in einem einzigen Arbeitsgange vor sich gehen kann, ohne dass sich am Werkstücke Falten bilden, selbst wenn dieses aus einem Werkstoffe von grösster Härte und Festigkeit besteht.

Punch for thin sheets such as palatal plates and the like like
The invention relates to punching for thin sheets, such as palatal plates u. Like., and aims to give such sheets the desired shape in a single operation without creases forming in the work piece. This wrinkling should not occur even if the hardest material is used, e.g. B. Steel, especially those chrome-nickel steel that is very resistant to attack by acids.
The drawing shows an exemplary embodiment intended for the production of palatal plates
EMI1.1
Workpiece and die in the position at the beginning of the punching process, FIG. 2 a corresponding section in a position occurring during the punching process and FIG. 3 a corresponding section in the position after the end of the punching process.
A denotes the die and B the sheet metal forming the workpiece. The punch C consists in its parts intended to rest on the work piece in a known manner from a plastic material, e.g. B. lead. According to the invention, this part of the punch C is designed so that the workpiece B is clamped between the punch and the die as early as possible on the upstanding edges a1 of the die, as can be seen in particular from FIG.
In the course of the punching process, the punch C nestles more and more closely to the shape of the die due to its malleability (FIGS. 2 and 3), while at the same time the center of the sheet B is gradually pressed into the die cavity. Here, the sheet B is pulled through at the upstanding edges a1 of the die A in accordance with the increasing material requirements between the die and the punch, overcoming the jamming generated by the pressure of the punch.
Compared to known similar devices, by clamping the sheet B to the upstanding edges of the forming die, the advantage is achieved that the punching can take place in a single operation without creases forming on the work piece, even if it is made of a very large material Hardness and strength.
