Verfahren zur Herstellung von Blechen mit Hohlrippen.Process for the production of sheet metal with hollow ribs.
Patentiert im Deutschen Reiche vom 22. Oktober 1912 ab.Patented in the German Empire on October 22, 1912.
Für die Verstärkung von aus Beton herzustellenden Wänden werden Bleche verwendet, die mit im Abstand voneinander befindlichen Hohlrippen versehen sind, und bei denen die zwischen diesen Rippen gelegenen Blechstreifen durch Ausstanzen mit vorspringenden Zungen u. dgl. versehen sind. Vorliegende Erfindung bezieht sich auf ein Verfahren, das die Herstellung solcher Bleche bis auf das Ausstanzen,Sheets are used to reinforce walls made of concrete, which are provided with spaced apart hollow ribs, and in which the sheet metal strips located between these ribs by punching with protruding tongues and the like are provided. The present invention relates to a method of manufacturing such sheets except for the punching,
ίο das erst nach diesem Verfahren stattfindet, bezweckt. Es ist vorauszuschicken, daß bereits Verfahren und Maschinen bekannt sind, in denen ebenes Blech in einem laufenden Arbeitsgang zu Wellblech umgestaltet wird. Dies geschieht z. B. dadurch, daß das ebene Blech zwischen Ziehstempel geleitet wird, die von endlosen Ketten getragen werden und das Blech zwischen sich erfassen und allmählich in Wellblech umwandeln. Die die Ziehstempel tragenden Ketten sind so über Walzen geführt, daß sie vom Eintrittsende der Maschine bis zum Ausgang keilförmig. gegeneinanderlaufen, so daß die Bildung der Wellen bis auf eine gewünschte Tiefe allmählich vor sich geht.ίο which only takes place after this procedure, aims. It is to be said in advance that methods and machines are already known in where flat sheet metal is transformed into corrugated sheet metal in one operation. this happens z. B. in that the flat sheet is passed between drawing punches, which are carried by endless chains and that Grasp sheet metal between you and gradually transform it into corrugated sheet metal. The drawing die bearing chains are guided over rollers that they are from the entry end of the machine wedge-shaped to the exit. run against each other, so that the formation of waves except for one desired depth is gradually going on.
Ferner ist eine Maschine bekannt, in der bereits streifenweise mit ausgestanzten Zungen versehene Bleche gestreckt werden. Diese Maschine ist so eingerichtet, daß die zwischen den ausgestanzten Blechstreifen verbleibenden unverletzten und bereits vorher oder beim Eintritt in die Maschine zu Hohlrippen gestalteten Blechstreifen durch Rollen mit entsprechendem Querschnitt eine sichere Führung erhalten. Schließlich ist auch ein Verfahren zur Herstellung von Feuerbüchsen bekannt geworden, bei dem zunächst eine gleichförmige Wellung des Rohres und dann eine Umgestaltung der Wellenberge zu Hohlrippen mit steilen Wänden vorgenommen wird. Die Hohlrippen behalten dabei denselben Abstand wie die Wellenberge, aus denen erstere gebildet werden. Infolgedessen erfährt das zwischen den Wellenbergen gelegene und die Wellentäler bildende Material eine Dehnung.Furthermore, a machine is known in which already strips with punched out tongues provided sheets are stretched. This machine is set up so that the between the punched sheet metal strips remaining uninjured and already before or upon entry into the machine to form hollow ribs sheet metal strips by rolling with the appropriate Cross-section get a safe guidance. Finally, there is also a method of manufacture of fire boxes became known, in which initially a uniform corrugation of the pipe and then a redesign of the wave crests to hollow ribs with steep walls is made. The hollow ribs keep the same distance as the wave crests, from which the former are formed. As a result, this experiences between the wave crests located material and the wave troughs forming an elongation.
Vorliegendes Verfahren zur Herstellung von Blechen mit Hohlrippen besteht nun darin, daß aus einem mit gleichförmigen Wellen versehenen Blech nur jede zweite Welle zu einer Hohlrippe umgestaltet wird, daß aber die übrigen Wellen entweder ohne weiteres oder nach mehrmaligem Durch- und Zurückbiegen flachgepreßt werden, so daß das infolge ihrer Streckung über den Querschnitt des Bleches frei werdende Material dazu benutzt werden kann, die Wände der Hohlrippen steil aufzustellen, ohne daß die flachzupressenden Wellen eine Dehnung und Schwächung erfahren. Das mehrmalige Hin- und Herbiegen der flach zu pressenden Wellen verfolgt dabei den Zweck, das Material an diesen Stellen zu enthärten, damit es für die nachfolgende Bearbeitung in der Stanze geeigneter ist. Für das beschriebene Verfahren können bereits vorgewellte Bleche verwendet werden. . Es ist jedoch zweckmäßiger, die Wellung ebenen Bleches und die Ausgestaltung einzelner Wellen desselben zu Hohlrippen in einem laufenden Arbeitsgange vorzunehmen, wie dies nachfolgend beschrieben ist, ohne daß dies als Merkmal der Erfindung angesehen wird.The present method for the production of metal sheets with hollow ribs consists in that from sheet metal provided with uniform corrugations, only every second corrugation becomes a hollow rib is rearranged, but the remaining waves either without further ado or after several times Bending and bending back are pressed flat, so that as a result of their stretching over the Cross-section of the sheet material released can be used to make the walls of the To erect hollow ribs steeply without the waves to be pressed flat and stretching Experience weakening. The repeated bending back and forth of the waves to be pressed flat pursues the purpose of softening the material at these points so that it can be used for the following Processing in the punch is more suitable. For the procedure described you can pre-corrugated sheets can be used. . However, it is more practical to level the corrugation Sheet metal and the design of individual waves of the same to form hollow ribs in one go Perform operations as described below, without this being a feature of the Invention is considered.
Die Zeichnungen stellen ein Beispiel einer zur Ausführung des vorligenden Verfahrens geeigneten Maschine dar. Fig. 1 bis 9 erläutern die verschiedenen Querschnittsformen, die das ebene Blech nach Fig. 1 beim Durchgang durchThe drawings illustrate an example of one for carrying out the present method suitable machine. Figs. 1 to 9 illustrate the various cross-sectional shapes that the flat sheet of Fig. 1 when passing through
