Description
Es sind.--Grubenstempel, insbesondere Innenstempel, mit im Querschnitt kastenförmigem Profil bekannt, welches aus zwei an den gegeneinander gerichteten Flanschen miteinander verschweißten E-Profilen besteht. Profile dieser Art haben den Nachteil, daß eine Verschweißung der gegeneinander gerichteten Mittelrippen schwierig durchzuführen ist.There are - pit punches, especially inner punches, with in cross section box-shaped profile known, which consists of two against each other Flanges welded together E-profiles. Have profiles of this type the disadvantage that a welding of the mutually directed central ribs difficult to do.
Durch die Erfindung wird das Verschweißen der Mittelrippe dadurch in einfacher Weise ermöglicht, daß mindestens ein Schenkel eines E-Profils vor dem Verschweißen der Mittelrippen beider Profile nach auswärts. zurückgebogen 'wird. Durch den zwischen den auseinandergebogenen Außenschenkeln der E-Profile gebildeten Spalt ist nunmehr der Zutritt zu der Stoßstelle der Mittelrippen leicht möglich, so daß eine einwandfreie Schweißverbindung hergestellt werden kann. Im Anschluß an das Verschweißen der Mittelrippen werden dann die Außenschenkel gegeneinander gebogen und ebenfalls. verschweißt.By the invention, the welding of the central rib is thereby allows in a simple manner that at least one leg of an E-profile before Welding the central ribs of both profiles outwards. is bent back '. By the formed between the bent outer legs of the E-profiles Gap is now easily accessible to the joint of the central ribs, so that a perfect welded connection can be made. In connection The outer legs are then welded to one another at the welding of the central ribs bent and also. welded.
Ein besonders zweckmäßiges Verfahren besteht darin, daß mindestens ein Schenkel des E-Profils mitsamt der zwischen ihm und der Mittelrippe liegenden Steghälfte zurückgebogen wird und daß nach dem Verschweißen der Mittelrippe dieser Schenkel durch einen Druck auf die abgebogene Steghälfte gegen den Schenkel des Nachbarprofils angedrückt und verschweißt wird. Zweckmäßig werden beide Schenkel jedes Profils einschließlich der zugehörigen Steghälften um die Mittelrippe zurückgebogen. Nach dem Verschweißen des Mittelsteges kann man dann die beiden Profile unter zwei ebenen Gcsenken zusammenpressen. -Zur Durchführung .des Verfahrens nach. der Erfindung können E-Profile normaler Bauart verwendet werden. Zweckmäßiger- ist es aber, die Profile gleich bei der Herstellung, z. B. beim Walzen., so zu formen, daß die Schenkel einschließlich der benachbarten Steghälften um die Mittelrippe in dem erforderlichen Maß zurückgebogen sind. Die Profile können aus- Stahl oder auch aus Leichtmetall hergestellt sein.A particularly useful method is that at least one leg of the E-profile together with the one lying between it and the central rib Web half is bent back and that after welding the central rib this Leg by pressing the bent half of the bridge against the leg of the Neighboring profile is pressed and welded. Both legs are useful each profile including the associated web halves bent back around the central rib. After welding the middle bar, you can then put the two profiles under two Press flat countersinks together. -To carry out .the procedure according to. the invention E-profiles of normal design can be used. It is more expedient, however, that Profiles during production, e.g. B. When rolling. To shape so that the legs including the adjacent web halves around the midrib in the required Dimension are bent back. The profiles can be made of steel or light metal be made.
In der Zeichnung ist das Verfahren nach der Erfindung beispielsweise veranschaulicht.In the drawing, the method according to the invention is for example illustrated.
Abb. i zeigt das Verschweißen. der Mittelrippen; Abb. 2 zeigt das fertige Kastenprofil.Fig. I shows the welding. the midrib; Fig. 2 shows this finished box profile.
Wie aus Fig. i zu erkennen ist, werden zur Herstellung des Innenstempels, zwei E-Profile verwendet, deren Schenkel i mitsamt der an jeden Schenkel anschließenden Steghälfte 2 etwa in Höhe der Ansatzstelle der Mittelrippe 3 um einen kleinen Winkel zurückgebogen-sind, derart, d'aß beim Aneinanderfügen der Mittelrippen 3 der gegenüberliegenden Profile zwischen den Schenkeln ein Zwisc_ henraum h verbleibt, durch welchen mittels einer Elektrode q. oder eines anderen Schweißgerätes die Verschweißung der Mittelrippen vorgenommen werden kann;. Nach diesem Verschweißen der Mittelrippen werden die beiden Profile unter zwei schematisch angedeuteten, mit ebenen Flächen versehenen Gelenken 5 zusammengepreßt, wobei sich die Schenkel i gegeneinander abstützen und dann durch Schweißung verbunden werden können, wie dies aus Fig. 2. zu erkennen ist.As can be seen from Fig. I, for the production of the inner stamp, two E-profiles are used, the legs of which i together with the one adjoining each leg Web half 2 approximately at the level of the attachment point of the central rib 3 at a small angle are bent back, in such a way, d'ass when the central ribs 3 of the opposite ones are joined together Profile between the legs a space h remains through which means an electrode q. or another welding device to weld the central ribs can be made ;. After this welding of the center ribs, the two Profiles under two schematically indicated joints provided with flat surfaces 5 pressed together, the legs i being supported against each other and then through Weld can be connected, as can be seen from Fig. 2.
