Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist die besondere Ausgestaltung einer Stanze zur Erzeugung viereckiger oder runder Löcher in Rund- oder Vierkanteisen, Winkel- oder Flacheisen, und zwar Löcher, deren Durchmesser kleiner ist als die Stärke des zu lochenden Werkstückes. Dieses Lochen erfordert besondere Einrichtungen, da bei der Länge des zu durchstoßenden Materials leicht ein Abbrechen des Stempels erfolgen kann. Die vorliegende Stanze benutzt das an sich bekannte Lochen von beiden Seiten des Arbeitsstückes aus, und da hierbei ein glattes Loch nicht zu erreichen ist, ist an derselben eine zweite Vorrichtung angebracht, die nach Art der gewöhnlichen Lochmaschinen im zweiten Arbeitsgange das Loch glatt durchstößt.The present invention relates to the special design of a punch for production square or round holes in round or square iron, angle or flat iron, namely holes whose diameter is smaller than the thickness of the workpiece to be punched. This punching requires special Facilities, since break off easily with the length of the material to be pierced of the stamp can be done. The present punch uses what is known per se Punch from both sides of the work piece, and there a smooth hole cannot be reached, a second device is attached to the same, which according to Art of ordinary punching machines punctures the hole smoothly in the second operation.
In beiliegender Zeichnung ist die Stanze in Fig. I im Längsschnitt und in Fig. 2 im Grundriß dargestellt.In the accompanying drawing, the punch is shown in Fig. I in longitudinal section and in Fig. 2 in Floor plan shown.
Die rechts befindliche Stanze hat eine feststehende (a) und eine durch Exzenterhebel bewegliche, konisch oder pyramidenartig zugespitzte Patrize b, die beide sich aber höchstens bis zur leichten Berührung ihrer Spitzen gegeneinander bewegen können. Wird nun ein Vierkant oder Rundeisenstab zwischen beide Spitzen gebracht und der Hebel c angezogen, so erhält z. B. ein Rundeisenstab eine Lochquerschnittsform, wie sie das Rundeisen/ (in Fig. 1) in der linken Stanzvorrichtung aufweist. Wird das nun vorgestanzte Eisen in diese linke Stanzvorrichtung gebracht, so braucht durch die zweite Stanze e die vorgestanzte Öffnung nur erweitert zu werden.The punch on the right has a fixed (a) and a conical or pyramidal tapered male part b which can be moved by eccentric levers, but both of which can move against each other at most until their tips touch each other lightly. If a square or round iron bar is brought between the two tips and the lever c is tightened, z. B. a round iron rod has a hole cross-sectional shape, as it has the round iron / (in Fig. 1) in the left punching device. If the now pre-punched iron is brought into this left punching device, the pre-punched opening only needs to be widened by the second punch e.
Zur Zentrierung des Eisenstabes dient eine beliebige Klemmvorrichtung mit Backen η und beliebigem Mechanismus, der die beiden Backen gleichmäßig zusammendrückt, wenn ein Hebelarm I angezogen wird. Hierzu kann mit Vorteil statt einer Spannschraube mit Rechts- und Linksgewinde eine Spannvorrichtung genommen werden, die aus einer dachförmigen Platte i besteht, die in eine ebensolche Platte mit sattelförmigem Einschnitt einschnappt oder sich auf deren Rändern festsetzen kann.Any clamping device with jaws η and any mechanism that presses the two jaws together evenly when a lever arm I is tightened is used to center the iron rod. For this purpose, instead of a tensioning screw with right and left threads, a tensioning device can advantageously be used, which consists of a roof-shaped plate i which snaps into such a plate with a saddle-shaped incision or can be fixed on its edges.
