Description
DEUTSCHESGERMAN
Bei den meisten bisher bekannten Stuf anpressen sind alle Arbeitsstempel auf einem gemeinsamen Träger angeordnet, an den die Verstellmittel, in der Regel die Pleuel einer Kurbelwelle, angreifen. Die Länge und die Verdrehungsbeanspruchung dieser Kurbelwellen, die an irgendeiner Stelle über Zahnräder angetrieben und abschnittsweise auf Verdrehung beansprucht werden, ist bei Pressen von einer gewissen Anzahl von Arbeitsstempeln ab beachtlich. Hinzu kommt, daß die Kurbelwellen aus fertigungstechnischen Gründen teuer sind.In most of the previously known Stuf presses, all working rams are on a common carrier arranged on which the adjusting means, usually the connecting rods of a crankshaft, attack. The length and the torsional stress on these crankshafts, which are driven at any point via gears and are subjected to torsion in sections, is of a certain degree in the case of presses Number of work stamps from considerable. In addition, the crankshafts from manufacturing Reasons are expensive.
Um diesen Nachteil zu vermeiden, hat man vorgeschlagen, jeden Pleuel für sich durch eine eigene Kurbelwelle anzutreiben, die in den Ständern der Presse gelagert sind. Die Kurbelwellen sind mit Zahnkränzen versehen, die im Eingriff mit den Ritzeln der Antriebswelle bzw. einer Vorgelegewelle stehen. Durch diese Maßnahme erhält man sehr kurze und widerstandsfähige Kurbelwellen.In order to avoid this disadvantage, it has been suggested to separate each connecting rod with its own To drive the crankshaft, which are stored in the uprights of the press. The crankshafts have sprockets which are in engagement with the pinions of the drive shaft or a countershaft. By this measure results in very short and robust crankshafts.
Es sind auch Stufenpressen mit in einer Reihe nebeneinander angeordneten Arbeitsstempeln bekannt, die einzeln über auf einer gemeinsamen Welle angeordnete Exzenter angetrieben sind.There are also known transfer presses with working rams arranged next to one another in a row, which are individually driven via eccentrics arranged on a common shaft.
Bei allen diesen bekannten Ausführungen von Stufenpressen ist der Nachteil vorhanden, daß die Bewegungsphasen der einzelnen Arbeitsstempel bzw. der Verstellmittel, der Pleuel oder Druckstangen, alle gleich sind. Dadurch muß sowohl das Pressengestell als auch das aufzubringende Drehmoment nach der Gesamtpreßraft aller Arbeitsstempel bemessen werden, was schwere Ständer und hohe Antriebsleistungen erfordert, die den Preis _der Presse maßgeblich beeinflussen.In all of these known designs of transfer presses there is the disadvantage that the movement phases the individual work stamps or the adjustment means, the connecting rods or push rods, all the same are. As a result, both the press frame and the torque to be applied must depend on the total pressing force all working rams are measured, which requires heavy columns and high drive powers, which significantly influence the price of the press.
Nach der Erfindung wird für Stufenpressen mit in einer Reihe nebeneinander angeordneten, einzeln über Exzenter angetriebenen Arbeitsstempeln vorgeschlagen, die Exzenter so anzuordnen, daß sie zueinander winkeleinstellbar sind. Dadurch können die Bewegungsphasen der Druckstangen für die einzelnen Arbeitsstempel so gewählt werden, daß als Gesamtpreßkraft nur etwa eine Kraft erforderlich ist, die im wesentlichen der Preßkraft für den Arbeitsstempel entspricht, der den größten Kraftbedarf hat.According to the invention is for transfer presses arranged in a row next to each other, individually over Eccentric driven working rams proposed to arrange the eccentrics so that they are to each other are angle adjustable. This allows the phases of movement of the push rods for each Working ram can be chosen so that only about a force is required as the total pressing force, which in the essentially corresponds to the pressing force for the working ram, which has the greatest power requirement.
Vorzugsweise werden die Exzenter je an einem auf der gemeinsamen Achse lose gelagerten Zahnrad angeordnet und von auf einer Vorgelegewelle undrehbaren, aber axial verschiebbaren und dadurch für eine Winkelverstellung der Exzenter entkuppelbaren Ritzeln angetrieben. The eccentrics are preferably each arranged on a toothed wheel loosely mounted on the common axis and driven by pinions that are non-rotatable on a countershaft, but axially displaceable and thereby disengageable for angular adjustment of the eccentrics.
Bei dieser Antriebsanordnung wird insofern vom Stande der Technik Gebrauch gemacht, als es bei Ziehpressen schon bekannt ist, einen mit einem Zahnrad verbundenen Exzenter auf einer Achse umlaufen zu lassen und über ein Ritzel einer Vorgelegewelle anzutreiben.In this drive arrangement, use is made of the state of the art insofar as it is in Drawing presses is already known to rotate an eccentric connected to a gear on an axis to leave and to be driven by a pinion of a countershaft.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in einer Ansicht, teilweise im Schnitt, dargestellt. In the drawing, an embodiment of the invention is shown in a view, partially in section.
Die beiden Ständer 1 und 2 der Presse sind durch einen Tisch 3, Traversen 4, 4 a, eine Achse 5 und eine Vorgelegewelle 6 miteinander verbunden. Die einzelnen Arbeitsstempel 7 α- bis 7 d sind in der Traverse 4 geführt und über Schraubspindeln 8 mit Stößeln 9 verbunden, an die von Exzentern 11 α angetriebene Druckstangen 10 angreifen. Die Exzenter 11 α bilden mit Stirnzahnrädern 11 eine Einheit, wobei sie auch als miteinander verbundene Einzelstücke ausgebildet sein können. Die Stirnräder 11 sind lose drehbar auf der Achse 5 angeordnet und stehen im Eingriff mit Ritzeln 12, die durch Keile 13 drehfest, jedoch lösbar und axial verschiebbar auf der Vorgelegewelle 6 angeordnet sind. Die Lage der Arbeitsstempel 7 a bis 7 d gegenüber ihrem Gegenwerkzeug auf dem Pressentisch 3 bzw. gegenüber dem Werkstück ist durch je ein Schneckengetriebe 14, 15 einstellbar.The two columns 1 and 2 of the press are connected to one another by a table 3, cross members 4, 4 a, an axis 5 and a countershaft 6. The individual punch 7 α- to 7 d are performed in the cross member 4 and connected via threaded spindles 8 with plungers 9, engage the α of eccentrics 11 driven push rods 10th The eccentrics 11 α form a unit with spur gears 11, and they can also be designed as individual pieces connected to one another. The spur gears 11 are loosely rotatably arranged on the axis 5 and are in engagement with pinions 12, which are arranged on the countershaft 6 in a rotationally fixed manner by means of wedges 13, but are detachable and axially displaceable. The position of the working punches 7 a to 7 d with respect to their counter tool on the press table 3 or with respect to the workpiece can be adjusted by means of a worm gear 14, 15 each.
Um eine Verschiebung der Bewegungsphasen der einzelnen Arbeitsstempel 7 a bis 7c? bzw. eine Winkelverstellung der Exzenter 11 a zn ermöglichen, brauchen lediglich die drehfesten Verbindungen der Ritzel 12 mit der Vorgelegewelle 6 durch Lösen der Keile 13 aufgehoben und die Zahnräder 11 gegenüber den Ritzeln 12 durch Versetzung um einen oder mehrere Zähne in eine entsprechende Lage zueinander gebracht zu werden.In order to shift the phases of movement of the individual working rams 7 a to 7 c? or an angle adjustment of the eccentric 11 a zn, only need the non-rotatable connections of the pinion 12 with the countershaft 6 canceled by loosening the wedges 13 and brought the gears 11 relative to the pinions 12 by offsetting one or more teeth in a corresponding position to each other to become.
Die getriebliche Verbindung zwischen den Ritzeln 12 und Stirnrädern 11 kann auch in irgendeiner anderen Form gelöst werden, beispielsweise dadurch, daß man die ganze Vorgelegewelle 6 mitsamt ihrem Antriebszahnrad 16 axial verschiebbar anordnet.The geared connection between the pinions 12 and spur gears 11 can also be in any other Form can be solved, for example, by the fact that the entire countershaft 6 together with its drive gear 16 arranged axially displaceable.
