Description

Das Patent 828 085 bezieht sich auf ein Profil für den Streb- und Streckenausbau, insbesondere für mehrteilige eiserne Grubenstempel mit einem kreuzförmigen Innenstempel, wobei an den äußeren Enden der Kreuzschenkel Werkstoffanhäufungen vorgesehen sind. Das Kreuzprofil kann aus zwei etwa V-förmigeri Walzprofilen zusammengesetzt sein. Das Profil soll den heutigen Anforderungen in bezug auf hohe Druckaufnahme voll entsprechen, gleichzeitig aber wirtschaftlich hergestellt werden können und leicht zu handhaben sein.The patent 828 085 relates to a profile for the face and Extension of the line, especially for multi-part iron pit punches with a cross-shaped one Inner punch, with material accumulations at the outer ends of the cross legs are provided. The cross profile can be composed of two approximately V-shaped rolled profiles be. The profile is intended to meet today's requirements with regard to high pressure absorption fully correspond, but at the same time can be produced economically and be easy to use.

In Weiterentwicklung dieses Erfindungsgedankens schlägt die vorliegende Erfindung vor, die beiden V-förmigen Teilprofile (Walzprofile) an ihrer Basis derart auszubilden, daß beim Zusammensetzen ein kleiner hohler Kern entsteht, zu dem Zwecke, daß kleine Anlageflächen für eine Stumpfschweißung entstehen. Um zu diesem Vorteil auch noch denjenigen eines hohen Trägheitsmomentes hinzuzufügen, wird ferner vorgeschlagen, das Profil mit einem größeren hohlen Kern zu versehen.In a further development of this inventive concept, the present one proposes Invention before the two V-shaped partial profiles (rolled profiles) at their base in such a way to develop a small hollow core when assembling, for the purpose of that small contact surfaces arise for a butt weld. To this advantage also to add that of a high moment of inertia, it is also proposed that to provide the profile with a larger hollow core.

Die Zeichnung stellt zwei Ausführungsbeispiele des Erfindungsgedankens im Querschnitt dar.The drawing represents two exemplary embodiments of the concept of the invention in cross section.

Die beiden dargestellten vierarmigen Kreuzprofile setzen sich aus den Walzprofilen i und i' zusammen, wobei das Profil gemäß Abb. i einen kleinen hohlen Kern aufweist, während das Profil nach Abb.2 einen größeren Hohlkern zeigt. Bei gleichen äußeren Abmessungen der Arme wird das Trägheitsmoment mit zunehmender Größe des Hohlkerndurchmessers größer, wodurch eine ent- sprechende Abstufung der Lastaufnahmemöglich- keit der einzelnen Stempel gegeben ist. Der Hohl- kern des Profils kann sowohl rund sein als auch jede eckige Form aufweisen, wobei die Wahl der Formart von der wirtschaftlichen `Falzmöglichkeit abhängen wird. The two four-armed cross profiles shown are composed of the rolled profiles i and i ', the profile according to Fig. I having a small hollow core, while the profile according to Fig.2 shows a larger hollow core. With the same external dimensions of the arms, this becomes Moment of inertia with increasing size of the The hollow core diameter is larger, which meaningful gradation of the load-bearing possible individual stamp is given. The hollow The core of the profile can be either round or any angular shape, with the choice of Form type from the economic `folding possibility will depend.
