Description

Der Stempel nach dem Patent 83 i 386 ist dadurch gekennzeichnet, daß zwei ineinanderfügbare Rohre oder Körper zu mehrgängigen, spiralförmig verlaufenden Schraubengängen verformt sind, wobei der Stempelkopf drehbar gelagert ist, ferner die Schraubenspindel durch Kugeln, Rollen oder hretnsdübel festgelegt, gebremst und wieder gelöst werden kann.The stamp according to patent 83 i 386 is characterized in that two tubes or bodies that can be nested into one another to form multi-thread, spiral-shaped ones Screw threads are deformed, wherein the punch head is rotatably mounted, further the screw spindle is fixed by balls, rollers or dowels, braked and can be solved again.

DieLängenverstellbarkeit dieses Stempels ist nur einseitig und in vielen Fällen unhandlich beim Ein-und Ausbau. Auch wird in vielen Fällen das Rauben (Rückgewinnung) nicht schnell genug vor sich gehen.The length adjustability of this stamp is only one-sided and in often unwieldy when installing and removing. Also in many cases is robbery (Recovery) not happening fast enough.

Die Weiterentwicklung des Stempels nach Patent 831 386 besteht darin, durch besondere Ausbildung des Mittelteils des Stempels eine größere Längenverstellbarkeit zu erreichen.The further development of the stamp according to patent 831 386 consists in greater length adjustability due to the special design of the central part of the punch to reach.

In der Zeichnung ist der Stempel in drei Bildern dargestellt.In the drawing the stamp is shown in three pictures.

Der Stempel nach der vorliegenden Erfindung ist nach beiden Seiten hin ausziehbar und verstellbar. Die Stempelsäulen a bestehen aus jeweils links- und rechtsgängigen Gewinden (verformte Rohre), wobei der Stempelkopf h und die Fußplatte mit den Säulen fest verbunden ist.The stamp of the present invention is on both sides extendable and adjustable. The stamp columns a consist of left- and right-hand threads (deformed tubes), with the punch head h and the base plate is firmly connected to the pillars.

Bei dem Stempel nach Bild 2 ist in der Mitte des Stempels eine gabelkopfartige Ausklinkvorrichtung j vorgesehen, die durch einen Haltebolzen k gehalten und durch einen handgriffartigen Spanngriff 1 mit Sicherung m betätigt wird. Nach Lösen der Sicherungselemente in und L knickt -der Stempel zusammen; hierbei bleiben jedoch sämtliche Eisenteile mit .dem Stempel fest verbunden.In the case of the stamp according to Figure 2, a fork-head-like release device j is provided in the center of the stamp, which is held by a retaining bolt k and actuated by a handle-like clamping handle 1 with a fuse m. After loosening the securing elements in and L, the punch collapses; in this case, however, all iron parts remain firmly connected to the punch.

Die Ausführung nach Bild r zeigt die beiden Innensäulen e nach außen hin verlegt mit fest verbun-dener Stempelplatte und Fuß h, wobei die Längenverstellbarkeit, Verspannung, Lösen und Rauben mittels AuBensättle a vor sich geht.The design according to picture r shows the two inner columns e to the outside laid with a firmly connected stamp plate and foot h, whereby the length adjustability, Bracing, loosening and robbing by means of external saddles a is going on.

Die Ausführung nach Bild 3 zeigt die beiden Innensäulen e nach der Mitte des Stempels verlegt, wobei die Außensäulen a mit dem Stempelkopf und Fuß le versehen sind. Der Druckverlauf im Drehsinne, d. h. das Abbremsen, wird anstatt durch Rollen, Kugeln oder Dübel durch Kontern einer nippelartig verlagerten Mutter i erreicht.The design according to Figure 3 shows the two inner columns e after Relocated in the middle of the punch, the outer columns a with the punch head and foot le are provided. The pressure curve in the direction of rotation, d. H. braking, instead by means of rollers, balls or dowels by countering a nut displaced like a nipple i achieved.
