Description
Die Erfindung betrifft eine Mehrständerpresse o.dgl. Pressenanlage zum Formen von Blechteilen mit einander gegenüberstehenden Pressenständern. Pressenanlagen dieser Art dienen dem Umformen einer Platine, Ronde o.dgl. Blechteile, wobei in der ersten Stufe das Ziehen zur Erzeugung der Ausgangsform für die weitere Formgebung vorgesehen sein kann. Die Erfindung betrifft solche Mehrständerpressen mit mehreren, zumindest zwei Pressenstößeln, wobei der Stößelantrieb oberhalb des Pressenstößels angeordnet ist und bei denen die Krafteinleitung symmetrisch zu dessen Mittenlängsachse erfolgt.The invention relates to a multi-column press or the like. Press system for forming sheet metal parts with opposing press stands. Press systems of this type are used to form a blank, Round blank or the like Sheet metal parts, in the first stage pulling to Generation of the initial shape can be provided for further shaping can. The invention relates to such multi-column presses with several, at least two press rams, the ram drive above the Press ram is arranged and where the force application is symmetrical to its central longitudinal axis.
Derartige Pressenanlagen sind beispielsweise aus den Druckschriften US-A-4,102,174; DE-C2-31 18 955; DE-A1-39 05 068 und DE-A1-41 24 083 bekannt. Die letztgenannten Druckschriften zeigen die Verwendung mehrerer Pressenstößel in den der Ziehstufe nachfolgenden Folgestufen sowie Zischenablagen nach jeder Barbeitungsstufe. Diese hier gezeigten Pressenaufbauten sind teuer bei entsprechend hoher Bauteile-Anzahl. Such press systems are for example from the publications US-A-4,102,174; DE-C2-31 18 955; DE-A1-39 05 068 and DE-A1-41 24 083 known. The latter publications show the use several press rams in the subsequent stages following the drawing stage as well as hissing trays after each processing stage. These shown here Press assemblies are expensive with a correspondingly high number of components.
Aus der DE-A-26 57 911 ist eine Mehrständerpresse zum Formen von Blechteilen, mit Pressentischen, Pressenständern und mehreren von einem Pressenantrieb getriebenen Pressenstößeln bekannt. Die Getriebe zur Umlenkung der Drehbewegung des Motorantriebs der Presse in eine auf- und abgehende Bewegung der Pressenstößel sind oberhalb der Krafteinleitung in die Stößel zwischen jeweils einem Ständerpaar angeordnet. Im gemeinsamen Ständerpaar von zwei benachbarten Stößeln sind zwei Getriebe eingebracht, und die Krafteinleitung in die Pressenstößel erfolgt symmetrisch zu den Zugankern. DE-A-26 57 911 describes a multi-column press for forming sheet metal parts, with press tables, Press stands and several press rams driven by a press drive known. The gears to redirect the rotary motion of the motor drive of the press in an up and down movement of the press rams are above the force transmission in the plungers are arranged between a pair of stands. In the common pair of stands from two adjacent plungers, two gears are introduced, and the force is introduced into the Press ram is symmetrical to the tie rods.
Es ist ehe Aufgabe der Erfindung, die Länge des Gesamtproduktionsraumes unter Wegfall der Zwischenablagen zu verringern und die Antriebe der Pressenstößel in den Bereich früher vorhandener Leerstufenbereiche (Zwischenständerbereich) zu legen. Insbesondere soll hierbei der Antrieb von zwei aneinander stoßenden, (Folge-)Pressenstößeln aus eine Zwischenständerbereich heraus erfolgen.It is before the object of the invention, the length of the total production space while eliminating the clipboards and reducing the Press ram drives in the area of previously empty space areas (Intermediate stand area). In particular, here the drive of two (subsequent) press rams abutting each other from an intermediate stand area.
Diese Aufgabe ist gelöst bei einer der Pressenanlagen der zuvorgenannten Arten durch die Merkmale des Kennzeichens des Anspruchs. This object is achieved in one of the press systems of the aforementioned Species by the characteristics of the characterizing part of the claim.
Von besonderem Vorteil ist die Möglichkeit des unterschiedlichen Antriebs der benachbarten Pressenstößel.The possibility of different is of particular advantage Drive of the adjacent press rams.
Anhand eines in der Zeichnung gezeigten Ausführungsbeispiels soll im folgenden die Erfindung näher erläutert werden.Based on an embodiment shown in the drawing the invention will be explained in more detail below.
