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.

Die Pressenanlage umfaßt eine Anzahl Umformstufen 4, 5, die in Pressendurchlaufrichtung 6 - Werkstückdurchgang durch die Pressenanlage - einander folgen. Fig. 1 zeigt weiterhin Zuganker 3, die mit entsprechenden Zugankerbuchsen die eigentlichen Pressenständer 1 bzw. 2 bilden. Die einander gegenüberstehenden Pressenständer 2 weisen hier jeweils bei Zuganker 3 auf (auch Fig. 9), deren Mitten sich gemäß Fig. 5 auf einer gemeinsamen Mittenlinie 17 befinden. Die Pressenanlage weist weiterhin entsprechend Fig. 2 über Querträger auf dem Fundament aufgesetzte Pressentische 7 sowie vom Motorantrieb 13 des allgemein mit 12 positionierten Pressenantriebs über Getriebe in Getriebekästen 14, 15 und Pleuel 18 auf- und abbewegte Pressenstößel 8, 9 auf. Der Motorantrieb 13 wirkt gemäß Fig. 4 auf die Getriebekästen 14 und 15.The press system comprises a number of forming stages 4, 5, which in Press flow direction 6 - workpiece passage through the press system - follow each other. Fig. 1 also shows tie rods 3, the corresponding Tie rod bushes the actual press stands 1 and 2 form. The opposing press stands 2 point here each with tie rod 3 on (also Fig. 9), the centers of which according to Fig. 5 are on a common center line 17. The press system also has according to Fig. 2 on crossbeams on the foundation attached press tables 7 and the motor drive 13 of the general with 12 positioned press drives via gears in gear boxes 14, 15 and connecting rods 18 up and down moved press ram 8, 9. The motor drive 13 acts according to FIG. 4 on the gear boxes 14 and 15.

Wie es insbesondere Fig. 3 erkennen läßt, sind Werkzeughälften 10, 11 jeweils auf Pressentisch 7 bzw. Pressenstößel 8, 9 orientiert. Die gezeigten Pressenstößel 8, 9 überbrücken den ansonsten vorhandenen Freiraum zwischen den einander gegenüberstehenden Pressenständern 2 und sind getrennt über die unterschiedlich auslegbaren Getriebe in dem Getriebekasten 15 und dem jeweils anderen, ebenfalls im Zwischenständerbereich der Pressenständer 1 oder oberhalb dieser befindlichen Getriebe 14 antreibbar.3, tool halves 10, 11 each oriented on press table 7 or press ram 8, 9. The shown press ram 8, 9 bridge the otherwise existing Free space between the opposing press stands 2 and are separated by the differently designed gearbox in the Gear box 15 and the other, also in the intermediate stand area the press stand 1 or above it Gear 14 drivable.

Die Pressenstößel 8, 9 sind vermittels Kurbelwellen-, Kniehebel-(Glenk-), Exzentergetriebe u.dgl. Getriebemittel antreibbar.The press rams 8, 9 are by means of crankshaft, toggle (Glenk), Eccentric gear and the like Gear means drivable.

Wie es die Fig. 6, 7 und 8 zeigen, befinden sich die Getriebe in Getriebekästen 14 bzw. 15, die zwischen den Pressenständern 1 bzw. 2 oder oberhalb dieser untergebracht sind. Im letzteren Fall sind Zuganker 19 zur Befestigung des Getriebekastens 15 an den Pressenständern 2 bzw. an mit den Pressenständern 2 starr verbundenen Längsträgern vorgesehen. Die Fign. 7 und 8 lassen einen Getriebeaufbau, hier ein Kurbelwellengetriebe mit gleiche Abgriff für Pleuel 18 erkennen, wobei ein Pleuelpaar 18 an dem Pressenstößel 8, ein zweites Pleuelpaar 18 an dem Pressenstößel 9 angelenkt ist. Es versteht sich, daß die Getriebekästen 14 entsprechend dem in dem Getriebekasten 15 verwendeten Getriebe ausgelegt ist. Die Fig. 5 läßt die symmetrische Krafteinleitung 16 aus dem Getriebekasten 15 bzw. über die in diesem untergebrachten Getriebe in die Pressenstößel 8 und 9 erkennen.As shown in FIGS. 6, 7 and 8, the gears are in Gear boxes 14 and 15, respectively, between the press stands 1 and 2 or are housed above it. In the latter case, tie rods are used 19 for fastening the gear box 15 to the press stands 2 or on side members rigidly connected to the press stands 2 intended. The figures 7 and 8 allow a gearbox construction, here Recognize crankshaft transmission with the same tap for connecting rod 18, whereby a pair of connecting rods 18 on the press ram 8, a second pair of connecting rods 18 is articulated on the press ram 9. It is understood that the gear boxes 14 corresponding to that used in the gear box 15 Gearbox is designed. 5 leaves the symmetrical introduction of force 16 from the gearbox 15 or via the housed therein Recognize the gear in the press rams 8 and 9.
