Die bisher gebräuchlichen Stanzen wurden in der Weise hergestellt, dafs die Form des zu pressenden Gegenstandes in den Untertheil der Stanze eingearbeitet wurde, in welchen ein entsprechender Stempel bezw. Obertheil pafste. Die Herstellung solcher Stanzen war mit viel Mühe und Kosten verbunden und stark der Abnutzung unterworfen. Vorliegende Stanzen mit erhabenen Schneidrändern lassen sich jedoch sehr leicht verfertigen, liefern genaue und saubere Waare und sind viel dauerhafter als die bisher gebräuchlichen.The punches in use hitherto were made in such a way that the shape of the object to be pressed was incorporated into the lower part of the punch, in which a corresponding stamp respectively. Upper part passed. The manufacture of such punches was with a lot Effort and cost associated and subject to severe wear and tear. Present punches however, with raised cutting edges are very easy to manufacture, provide accurate and clean goods and are much more durable than the previously used ones.
In der beiliegenden Zeichnung ist:
Fig. ι ein Grundrifs eines Untertheiles einer Stanze,In the accompanying drawing is:
Fig. Ι a basic outline of a sub-part of a punch,
Fig. 2 ein Schnitt nach x-x der Fig. 1 und Fig. 3 ein Schnitt eines Obertheiles, ebenfalls nach x1-x1 der Fig. 1, wobei zu bemerken ist, dafs bei den vorliegenden Stanzen der Obertheil dem Untertheil gleich ist und sich nur in unwesentlichen, später zu beschreibenden Anordnungen unterscheidet.Fig. 2 is a section according to xx of Fig. 1 and Fig. 3 is a section of an upper part, also according to x 1 -x 1 of Fig. 1, whereby it should be noted that in the present punches the upper part is the same as the lower part and is different differs only in insignificant arrangements to be described later.
α ist der Untertheil der vorliegenden Stanze, an welchem die Form b des zu pressenden Gegenstandes derart hergestellt wird, dafs die Begrenzung derselben einen erhabenen Schneidrand c bildet. Der Obertheil d enthält dieselbe Form f mit dem erhabenen Schneidrand g, so dafs beim Niederführen bezw. Niederdrücken des Obertheiles der zu erzeugende Gegenstand ausgepreist wird. α is the sub-part of the present punch, on which the shape b of the object to be pressed is produced in such a way that the boundary of the same forms a raised cutting edge c . The upper part d contains the same shape f with the raised cutting edge g, so that when it is lowered or Depressing the upper part of the object to be produced is priced out.
Der einzige Unterschied zwischen Obertheil und Untertheil besteht darin, dafs letzterer Löcher h besitzt, durch welche die Enden eines Hebels wie bei gewöhnlichen Stanzen hindurchgehen, um den geprefsten Gegenstand aus der Form hinauszuwerfen.The only difference between the upper part and the lower part is that the latter has holes h through which the ends of a lever pass, as in ordinary punches, in order to throw the pressed object out of the mold.
Die Anwendung dieser Stanze geschieht in derselben Weise, wie bei den bisherigen Stanzen. Der Untertheil wird am Boden der Presse und der Obertheil am sogenannten Stofs befestigt, welch letzterer beim Niedergehen den zu erzeugenden Gegenstand stanzt bezw. preist.This punch is used in the same way as with the previous punch. The lower part is attached to the bottom of the press and the upper part to the so-called fabric, which latter punches the object to be produced when going down, respectively. praises.
