Description
Grubenstempel. Die Erfindung betrifft einen mehrteiligen nachgiebigen Grubenstempel mit oben und unten zusammengehaltenen schrägen Verbindungsflächen der einzelnen Teile. Das Neue besteht darin, daß die winklig ausgeschnittenen schrägen Verbindungsflächen der beiden Stempelteile durch eine Doppelzwinge aus zwei Ringen mit seitlichen Stellschrauben und verbindenden Stegen unter. Einsatz von Holzkeilen in den Zwischenraum zwischen Doppelzwinge und Stempelteilen zusammengehalten sind. Hierdurch kann der Stempel leicht und schnell eingebaut und wieder abgebaut werden. Die Zeichnung veranschaulicht die Erfindung in einer Ausführung, und zwar in Abb. r in einer Seitenansicht und in Abb. 2 in einem Querschnitt nach Linie fl-B in der Abb. r.Pit stamp. The invention relates to a multi-part flexible Pit punch with sloping connecting surfaces held together at the top and bottom of the individual parts. The new thing is that the bevels cut out at an angle Connection surfaces of the two stamp parts by a double clamp made of two rings with lateral adjusting screws and connecting webs underneath. Use of wooden wedges are held together in the space between the double clamp and punch parts. As a result, the stamp can be installed and dismantled again easily and quickly. The drawing illustrates the invention in one embodiment, namely in Fig. r in a side view and in Fig. 2 in a cross section along line fl-B in FIG Fig. R.
Die Doppelzwinge besteht aus zwei Ringen r, 2, die durch zwei gerade gegenüberliegende Stege 3, q., obgleich in gewissem Abstande, voneinander gehalten sind. Jeder Ring trägt in einer seitlichen Verstärkung eine Stellschraube 5 mit kegeligem Innenende 6 und äußerem Vierkant 7.The double clamp consists of two rings r, 2, which are straight through two opposing webs 3, q., although at a certain distance, held from each other are. Each ring carries an adjusting screw 5 in a lateral reinforcement conical inner end 6 and outer square 7.
Die beiden zu verbindenden Stempelteile 8, 9 werden an den Verbindungsstellen schräg zueinander abgeschnitten, und zwar so, daß die Höhe der Schrägfläche größer als die Gesamthöhe der Doppelzr' ; linge ist. Die Schrägfläche der beiden Stempelteile wird aber nicht eben, sondern winklig ausgebildet, so daß die beiden Teile sich nicht seitlich gegeneinander verkanten können, sondern zwangläufige Führung aneinander haben.The two punch parts 8, 9 to be connected are cut obliquely to one another at the connection points, in such a way that the height of the inclined surface is greater than the total height of the double zr '; thing is. The inclined surface of the two punch parts is not flat, but angled, so that the two parts cannot tilt laterally against each other, but have positive guidance on each other.
Um den Stempel nachgiebig zu gestalten, werden in den freien mondsicheligen Raum zwischen Stempel und Doppelzwinge an jedem Ringe beidseitig der Stellschraube fünf kleine Holzkeile i i von oben eingetrieben.In order to make the stamp pliable, crescent crescent are used in the free Space between punch and double clamp on each ring on both sides of the set screw five small wooden wedges i i driven in from above.
