Description
Nachgiebiger Grubenstempel Gegenstand der Erfindung ist ein nachgiebiger Grubenstempel mit Innen- und Außenstempel aus Winkeleisen und einem dreieckförmigen Keil, der sich mit zwei Flächen an die Innenwandungen des Innenstempels und mit der dritten Seite gegen eine Gleitfläche des nicht verschiebbaren Klemmschlosses anlegt. Derartige Grubensteihpel sind bekannt.Resilient pit ram The subject of the invention is a resilient Pit punch with inner and outer punch made of angle iron and a triangular shape Wedge, which has two surfaces on the inner walls of the inner stamp and with the third side against a sliding surface of the non-displaceable clamp lock applies. Such pit diggers are known.
Ein Grubenstempel mit Keil nach der Erfindung hat dem bekannten dreieckförmigen Keil gegenüber, bei dem eine zu breite Fläche gegen die Gleitfläche des Schlosses anliegt, die das Mitwandern des Keiles sehr in Frage stellt und deshalb Gefahrenmomente in sich birgt, den großen Vorteil, daß die schmalen Gleitflächen ein sicheres Mitwandern bedingen und jede Gefahr des Nichtarbeitens des Stempels ausschließen.A pit punch with a wedge according to the invention has the known triangular shape Wedge opposite, where too wide a surface against the sliding surface of the lock that puts the wedge's wandering into question and therefore dangerous moments has the great advantage that the narrow sliding surfaces ensure safe migration condition and exclude any risk of the stamp not working.
D.er Keil des Erfindungsgegenstandes hat dem bekannten Keil aus U-Eisen gegenüber, der nur mit einer Fläche am Innenstempel anliegt, den großen Vorteil, .daß er mit zwei Flächen anliegt und deshalb. sicherer mitwandert.D. The wedge of the subject of the invention has the well-known wedge made of U-iron compared to the one that is in contact with the inner punch with only one surface, the great advantage .that it rests with two surfaces and therefore. safer.
Eine Ausführungsform der Erfindung ist auf der Zeichnung dargestellt, und zwar zeigt Fig. i Längsschnitt eines Stempels, Fig. z Querschnitt desselben.An embodiment of the invention is shown in the drawing, namely Fig. i shows a longitudinal section of a stamp, Fig. z shows a cross section of the same.
Der Stempel besteht aus Unterstempel u, dem Oberstempel b, Keilstück c mit Fang-,eisend, dem festsitzenden Klemmschloß mit zwei Sperrbolzen, dem Gegenlager e mit Halteeisen f und dem Auffangeisen g.The stamp consists of lower stamp u, the upper stamp b, wedge piece c with catch, iron, the tight clamping lock with two locking bolts, the counter bearing e with the holding iron f and the catching iron g.
Bei dem gesperrten und unter Druck gesetzter Stempel wandert das Keilstück c mit dem Oberstempel so lange, bis sein Fangeisend das Auffangeisen g des Gegenlagers e erreicht hat. Die beiden Sperrbolzen mit Exzenterflächen gewährleisten das getrennte und sichere stufenweise Lösen des Stempels.When the punch is locked and pressurized, the wedge piece moves c with the upper punch until his catcher hits the catch g of the counter bearing e has reached. The two locking bolts with eccentric surfaces ensure that they are separated and safe gradual release of the punch.
