Description
Walzvorrichtung für Walzgut mit unterschnittenen Profilen Die Erfindung bezieht sich auf eine Vorrichtung zum Einrollen unterschnittener Profilteile vor oder hinter der Walze. Die Umlegevorrichtung besteht aus Rollen, welche dem umzulegenden Profil entsprechend geneigt an; geordnet sind.Rolling device for rolling stock with undercut profiles The invention relates to a device for rolling in undercut profile parts or behind the roller. The turning device consists of roles, which are to be turned over Profile inclined accordingly; are ordered.
In Abb. i hat das Profil p die unterschnittenen Profilkantena. Dieses Profil wird nunmehr gegen die Roller, geführt und von den. Rollen aus der Stellung a1 in die Stellung % gedrückt. Wird der Stab weiter vorgeschoben, so werden die Kanten von den Rollen r2 gefaßt und nunmehr in die endgültige Lage. e.3 hineingedrückt. Damit der Walzstab von den Walzen besser gefaßt wird, kann der Einführungskastenh in Pfeilrichtung etwas angehoben und wieder gesenkt werden, sobald die Walzen den Stab gefaßt haben.In Fig. I, the profile p has the undercut profile edgesa. This Profile is now directed against the roller, and by the. Rolling out of position a1 pressed to position%. If the rod is advanced further, the Edges taken by the rollers r2 and now in the final position. e.3 pressed in. So that the roller bar is better gripped by the rollers, the lead-in box slightly raised in the direction of the arrow and then lowered again as soon as the rollers reach the Have taken the baton.
Abb.2 zeigt dieselbe Vorrichtung in Draufsicht.Fig.2 shows the same device in plan view.
Statt der geschilderten Ausführung kann man die Rollen auch derart anordnen, daß, in der Walzrichtung gesehen, die Rollenachsen in zwei Ebenen geneigt und verstellbar angeordnet liegen.Instead of the described design, the roles can also be used in this way arrange that, seen in the rolling direction, the roller axes inclined in two planes and are adjustable.
Abb.3 und q.. In diesem Falle werden die Kanten a1 ,durch die RoU#en r allmählich, bis zu der fertigen Lage e.3 hineingedrückt.Fig.3 and q .. In this case the edges a1, through the RoU # en r gradually pressed in until the finished layer e.3.
Die Anzahl und die Form der Rollen kann. je nach dem gewünschten Zweck gewählt werden. Es können also auch mehrere Rollen paarweise hintereinander oder statt glatter Rollen kegelstumpfförmige oder profili;erbo Rollen angewendet werden. Zur weiteren Herabminderung der beim Durchgang des Walzstabes durch die Umlegevorrichtung auftretenden Reibung kann es von Vorteil sein, an Stelle einer festen Unterlage unter den das Umlegen des oder der Profilteile bewirkenden Rollen oder Rollenpaaren angetriebene oder frei umlaufende Rollen oder Walzen anzu, ordnen, die gegebenenfalls profiliert sein. oder eine andere, aus den Arbeitsbedingungen sich ergebende Form haben können.The number and shape of the roles can be. can be chosen according to the desired purpose. It is also possible to use several rollers in pairs one behind the other or, instead of smooth rollers, frustoconical or profiled rollers can be used. To further reduce the friction occurring when the roller bar passes through the folding device, it may be advantageous to arrange driven or freely rotating rollers or rollers that may be profiled instead of a solid base under the rollers or pairs of rollers that cause the folding of the profile part (s) be. or another form resulting from the working conditions.
