Abstract

In order to reduce the cross-section and thus the mass of the eccentric means (23, 27, 25) and the transmission means (4, 5) for the stroke adjustment of the press ram of a notching machine and the transverse forces occurring as a result of punching, the eccentric means are arranged at the fulcrum (7) between lever (5) and drive rod (4). The eccentric means are here designed in such a way that the centre (22) of the rotational axis of the eccentric shaft (23) and the centre (24) of the eccentric pin (27), during the times of the main punching movement of the press ram, lie on the centre longitudinal axis (21) of the drive rod (4), and that the bearing pin (25) of the actuating means (10) at the eccentric shaft, during the times of changed stroke position for punching omissions (13), facultatively for further, additional notches, then lies in the extension of the centre longitudinal axis (20) of the piston rod (16). <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung der im Oberbegriff des An­spruchs 1 angegebenen Art.The invention relates to a device of the type specified in the preamble of claim 1.

In beispielsweise Rotor- oder Ständerbleche sind Nuten, perio­disch angeordnete Gruppen von Nuten und zusätzlich Lochstanzungen je Hub vorzusehen. Von daher sind Stanzen, insbesondere Nutenstanzen und deren Werkzeuge so auszubilden, daß außer kontinuierlich einzubringen­den Nuten auch nach bestimmten, einstellbaren Zyklen einander abwech­selnde Gruppen von Nuten und weitere Löcher automatisch gestanzt wer­den können.In, for example, rotor or stator plates, grooves, periodically arranged groups of grooves and additionally punched holes per stroke are to be provided. For this reason, punches, in particular grooving punches and their tools, are to be designed in such a way that, in addition to continuously inserting grooves, alternating groups of grooves and further holes can also be punched automatically after certain adjustable cycles.

Während sich das Blech zwischen Oberwerkzeug und Unterwerkzeug schrittweise nach jedem Hub des Arbeitsstößels weiterbewegt, ist der Arbeitsstößel entsprechend dem vorgegebenen Zyklus zu beaufschlagen. Maßnahmen zur Antriebsunterbrechung des Arbeitsstößels sind un­günstig; jede Maßnahme, um Stanzauslassungen zu bewirken, zielt auf eine Veränderung der Hublage des Arbeitsstößels hin.While the sheet moves between the upper tool and the lower tool step by step after each stroke of the working ram, the working ram must be loaded according to the specified cycle. Measures to interrupt the working ram are unfavorable; every measure to cause die cuts is aimed at changing the stroke position of the working ram.

Bei einer Einrichtung nach der FR-PS 1 447 825, von der gattungs­gemäß ausgegangen wird, werden die Stanzauslassungen durch Hublagen­verstellung mittels eines verdrehbaren Exzenters erzielt, wobei der Arbeitsstößel, und somit das Oberwerkzeug, auch während der Stanzaus­lassungen bewegt werden. Im Kopfteil der gezeigten Stanze ist ein zweiarmiger Hebel in dem Gestell schwingbar gelagert. Das Lager wird durch den Exzenter gebildet, der über einen Lenker von einem Stellmit­tel drehbeaufschlagbar ist. Der Hebel ist in einem Endteil von einem Antrieb für Arbeits- und Zustellbewegungen beaufschlagbar; die Bewe­gung des Arbeitsstößels wird von dem anderen Endteil des Hebels abge­leitet. Der Drehantrieb des Bleches erfolgt über ein Schrittschaltge­triebe von dem gleichen Antrieb aus. Maßnahmen zur Steuerung des Stellmittels für die Exzenterverstellung im Zyklus von Stanzungen und Stanzauslassungen sind aus beispielsweise der DE 20 43 999 C3 be­kannt.In a device according to FR-PS 1 447 825, from which it is assumed that the punching omissions are achieved by adjusting the stroke position by means of a rotatable eccentric, the working plunger, and thus the upper tool, are also moved during the punching omissions. In the head part of the punch shown, a two-armed lever is swingably mounted in the frame. The bearing is formed by the eccentric, which can be rotated by an adjusting means via a link. The lever is in one end part of one Actuator for work and delivery movements can be loaded; the movement of the working ram is derived from the other end part of the lever. The sheet is driven by a stepping gearbox from the same drive. Measures for controlling the adjusting means for the eccentric adjustment in the cycle of punching and punching omissions are known from DE 20 43 999 C3, for example.

Aufgabe der Erfindung ist es, die Exzentermittel in den Übertra­gungsbereich an dem zweiarmigen Hebel mit den geringsten aufzunehmen­den Kräften zu integrieren.The object of the invention is to integrate the eccentric means in the transmission area on the two-armed lever with the lowest forces to be absorbed.

Die Lösung dieser Aufgabe gemäß dem Kennzeichen des Anspruchs 1 hat die Vorteile geringer Querschnittsabmessungen für die Gestaltung des Anlenkpunktes und somit die der geringen zu bewegenden Masse. Hierbei wird dann eine größere Exzentrizität in Kauf genommen, wenn die Verhältnisse an dem Hebel nicht 1 zu 1 ausgelegt sind. Weiterhin von Vorteil ist die Trennung der Maßnahmen für die Steuerung des Hu­bes des Arbeitsstößels für den Betrieb "Stanzen" und "Stanzauslas­sungen" von den Maßnahmen einer ausreichend großen Hubverstellung für den Werkzeugwechsel. Der erforderliche Hub für den Werkzeugwechsel ist unabhängig erzielbar. Bei dem Stanzen treten keine Querkräfte über den Exzenter auf. Querkräfte bei Stanzungen von zusätzlichen Löchern im sog. intermittierenden Betrieb können über z. B. den Druck­raum des Stellmittels abgestützt werden. Dadurch ist ein Stanzen auch in angehobener Stellung des Arbeitsstößels durchführbar. Anspruch 2 beinhaltet Merkmale einer bevorzugten Ausführungsform.The solution to this problem according to the characterizing part of claim 1 has the advantages of small cross-sectional dimensions for the design of the articulation point and thus that of the small mass to be moved. A greater eccentricity is accepted if the ratios on the lever are not designed 1: 1. Another advantage is the separation of the measures for controlling the stroke of the working ram for the operation "punching" and "punching omissions" from the measures of a sufficiently large stroke adjustment for the tool change. The required stroke for the tool change can be achieved independently. When punching, no transverse forces occur over the eccentric. Shear forces when punching additional holes in the so-called intermittent operation can z. B. the pressure chamber of the actuating means are supported. As a result, punching can also be carried out in the raised position of the working ram. Claim 2 includes features of a preferred embodiment.

Anhand des in den Figuren gezeigten Ausführungsbeispiels soll im folgenden die Erfindung näher erläutert werden.The invention will be explained in more detail below with reference to the exemplary embodiment shown in the figures.

Die Erfindung ermöglicht Stanzungen 12 in dem Blech 11 sowie Stanzauslassungen 13 entsprechend der Darstellung in Fig. 2.The invention enables die cuts 12 in the sheet metal 11 and die cutouts 13 as shown in FIG. 2.

Fig. 3 zeigt die Anordnung von zusätzlichen Nutungen 14 in dem Blech 11, die während der Bewegung des Arbeitsstößels bei Betriebs­stellung "intermittieren" für Stanzauslassungen 13 und bei der Haupt­stanzbewegung des Arbeitsstößels in das Blech 11 eingebracht werden.Fig. 3 shows the arrangement of additional grooves 14 in the sheet 11, which are "intermittent" during the movement of the working ram in the operating position for punching omissions 13 and during the main punching movement of the working ram in the sheet 11.

In den Fign. 4 und 5 ist der gestellfeste Druckzylinder 10 aus Ge­häuse 15 und Kolben mit Kolbenstange 16 über eine Lasche 18 an einem Lagerbolzen 25 der Exzenterwelle 23 angeschlossen. Mit 17 sind Dämp­fer positioniert.In Figs. 4 and 5, the frame-mounted pressure cylinder 10 consisting of housing 15 and piston with piston rod 16 is connected via a bracket 18 to a bearing pin 25 of the eccentric shaft 23. At 17 dampers are positioned.

Die Exzentermittel im Anlenkpunkt 7 bestehen aus der Exzenterwel­le 23, näher ersichtlich aus Fig. 6, dem Lagerbolzen 25, über den die Lasche 18 angeschlossen ist und dem angedrehten Exzenterzapfen 27. Mit 26 sind Lagerbuchsen zur Fixierung der Exzenterwelle 23 an dem He­bel 5, mit 28 ist ein Drehlager für die Antriebsstange 4 und mit 29 sind Lagerdeckel an der Antriebsstange 4 beziffert. Die Exzentrizität ist mit e gekennzeichnet als maximalem Abstand zwischen der Mitte 22 der Drehachse der Exzenterwelle und der Mitte 24 des Exzenterzapfens.The eccentric means in the articulation point 7 consist of the eccentric shaft 23, which can be seen in more detail in FIG. 6, the bearing bolt 25, via which the tab 18 is connected, and the turned-on eccentric pin 27. With 26, bearing bushes for fixing the eccentric shaft 23 to the lever 5 are also included 28 is a rotary bearing for the drive rod 4 and 29 are numbered bearing caps on the drive rod 4. The eccentricity is identified by e as the maximum distance between the center 22 of the axis of rotation of the eccentric shaft and the center 24 of the eccentric pin.

In der in Fig. 4 dargestellten Drehlage der Exzenterwelle 23 be­findet sich auch die Mitte 24 des Exzenterzapfens auf der Mittenlängs­achse 21 der Antriebsstange 4. Der in Fig. 1 gezeigte Arbeitsstößel 6 befindet sich in der über die Exzentermittel abgesenkten unteren Hub­lage, aus der Stanzungen durch Abwärtsbewogung, der Hauptstanzbewe­gung, vorgenommen werden.In the rotational position of the eccentric shaft 23 shown in FIG. 4, the center 24 of the eccentric pin is also located on the central longitudinal axis 21 of the drive rod 4. The working plunger 6 shown in FIG. 1 is in the lower stroke position, which is lowered via the eccentric means, from which punchings are made Downward movement, the main punch movement.

Entsprechend vorwählbarer Zyklen ist das Stellmittel 10 ansteuer­bar. Durch Verdrehen der Exzenterwelle 23 in die in Fig. 5 gezeigte Position wird der Arbeitsstößel 6 in eine Lage angehoben, in der das Oberwerkzeug nicht stanzt oder in der bei Stanzauslassungen 13 bei entsprechender Gestaltung des Oberwerkzeugs die in Fig. 3 gezeigten Stanzungen 14 vorgenommen werden. Die Längsachse 19 der Lasche 18, bzw. die Mitte des Lagerbolzens 25 an der Exzenterwelle 23, befinden sich in Längsausrichtung der Mitte 20 der Kolbenstange 16. Hierdurch werden die in Richtung der Mittenlängsachse 20 verlaufenden an sich geringeren Quer-Kräfte druckseitig in dem Stellmittel 10 aufgefangen. Es wirken keine Quer-Kräfte auf den Kolben.The actuating means 10 can be controlled in accordance with preselectable cycles. By rotating the eccentric shaft 23 into the position shown in FIG. 5, the working ram 6 is raised to a position in which the upper tool does not punch or in which the punching 14 shown in FIG. The longitudinal axis 19 of the bracket 18, or the center of the bearing pin 25 on the eccentric shaft 23, are located in the longitudinal direction of the center 20 of the piston rod 16. As a result, the generally lower transverse forces running in the direction of the central longitudinal axis 20 become pressure-side in the actuating means 10 caught. There are no transverse forces on the piston.
