The bottom ram stroke is controlled via a lever energised by an eccentric disc. The lever has an arm (29) on a lever axis (11) coupled to a hinged drive lever (6) and a control rod (30) interconnecting the two levers. The control rod is fitted with several alternative fastening points, pref. formed by a row of bores (7) in the drive lever.

Description

Die Erfindung betrifft eine Maschine zum Ansetzen von Nieten, Druckknöpfen oder dergleichen, mit einem Oberwerkzeug mit einem Oberstempel, einem Unterwerkzeug mit einem Unterstempel, einem Antrieb und einer Zuführvorrichtung, wobei der Ober- und Unterstempel über ein Getriebe mit dem Antrieb verbunden und relativ zueinander hin- und herbewegbar sind, wobei die Hubsteuerung für den Unterstempel über einen von einer Exzenterscheibe angesteuerten Hebel erfolgt.The invention relates to a machine for attaching rivets, push buttons or the like, with an upper tool with an upper punch, a lower tool with a lower punch, a drive and a feed device, the upper and lower punch connected to the drive via a gear and relative to one another - And are movable, the stroke control for the lower punch takes place via a lever controlled by an eccentric disk.

Derartige Maschinen zum Ansetzen von Nieten, Druckknöpfen oder dergleichen sind an sich bekannt. Eine derartige Maschine offenbart beispielsweise die DE-OS 42 25 264, bei welcher jedoch der Unterstempel nicht angetrieben ist und somit keine Ausgleichsbewegungen durchführt. Ungeachtet der Tatsache, ob der Unterstempel angetrieben ist oder nicht erfolgt bei den aus dem Stand der Technik bekannten Vorrichtungen keine Einstellung der Hubkraft und keine Berücksichtigung von Materialstärken. So werden bei größeren Materialstärken zum einen ein Wegausgleich benötigt, zum anderen aber eine Krafteinstellung.Such machines for attaching rivets, push buttons or the like are known per se. Such a machine is disclosed, for example, in DE-OS 42 25 264, in which, however, the lower punch is not driven and therefore does not carry out any compensating movements. Regardless of whether the lower punch is driven or not, the lifting force and the material thicknesses are not taken into account in the devices known from the prior art. In the case of larger material thicknesses, path compensation is required on the one hand, but force adjustment on the other.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Maschine der gattungsgemäßen Art dahingehend zu verbessern, daß unterschiedliche Materialstärken in jeweils gleicher Qualität bearbeitet werden können.It is therefore the object of the present invention to improve a machine of the generic type in such a way that different material thicknesses can be processed in the same quality.

Zur technischen Lösung dieser Aufgabe wird mit der Erfindung vorgeschlagen, daß der Hebel einen auf einer Achse angeordneten Hebelarm, einen mit diesem gelenkig verbundenen Antriebshebel und eine beide verbindende Steuerstange umfaßt, wobei mehrere alternative Befestigungspunkte für die Steuerstange angeordnet sind.To solve this problem technically, the invention proposes that the lever comprises a lever arm arranged on an axis, a drive lever articulated to it and a control rod connecting both, several alternative fastening points being arranged for the control rod.

Durch die erfindungsgemäße Ausgestaltung des Steuerhebels für den Unterstempel ist es möglich, durch die Variation der Befestigung für die Steuerstange zum einen einen Wegausgleich zum anderen über die Variation des Hebelarms einen Kraftausgleich herbeizuführen.The inventive configuration of the control lever for the lower punch makes it possible, on the one hand, to compensate the displacement by varying the fastening for the control rod, and on the other hand to compensate the force by varying the lever arm.

In vorteilhafter Weise wird vorgeschlagen, daß die alternativen Befestigungspunkte durch eine Reihe von am Antriebshebel ausgebildeten Bohrungen gebildet sind. Dadurch läßt sich die Steuerstange hinsichtlich des Kraftangriffspunktes am Antriebs-hebel verstellen, wodurch eine Krafteinstellung bewirkt wird.It is advantageously proposed that the alternative fastening points are formed by a series of bores formed on the drive lever. As a result, the control rod can be adjusted with respect to the point of application of force on the drive lever, whereby a force setting is effected.

Alternativ wird vorgeschlagen, daß die alternativen Befestigungspunkte durch eine Führungskurve in Form eines Langloches am Antriebshebel gebildet ist. Damit wird eine stufenlose Ver-stellbarkeit der Steuerstange am Antriebshebel bewirkt. In vorteilhafter Weise wird an der Führungskurve eine Skala angeordnet.Alternatively, it is proposed that the alternative fastening points be formed by a guide curve in the form of an elongated hole on the drive lever. This enables the control rod on the drive lever to be continuously adjusted. A scale is advantageously arranged on the guide curve.

Zur Unterstützung der Wegeinstellung wird in vorteilhafter Weise vorgeschlagen, daß die Steuerstange längenverstellbar ausgebildet ist. Gemäß einem Vorschlag der Erfindung wird dies dadurch realisiert, daß die Steuerstange eine Gewindestange mit einer Gewindehülse ist. Je nach Eindringtiefe der Gewindestange in die Gewindehülse läßt sich somit die Länge der Steuerstange und damit der Hubweg variieren.To support the travel setting, it is advantageously proposed that the control rod be adjustable in length. According to a proposal of the invention, this is realized in that the control rod is a threaded rod with a threaded sleeve. Depending on the depth of penetration of the threaded rod into the threaded sleeve, the length of the control rod and thus the stroke can be varied.

Die Erfindung ist nicht auf die konkrete Realisierung beschränkt. Anstelle einer Steuerstange kann auch eine Verbindungsplatte oder dergleichen eingesetzt werden. Darüber hinaus kann auch eine andere Art der starren Verbindung zwischen dem Antriebshebel und dem Hebelarm eingesetzt werden. Wesentlich ist, daß sich die Grundeinstellung, d. h. die Neigung des Hebelarms einstellen und sich ein Krafteinleitungspunkt variieren läßt.The invention is not limited to the specific implementation. Instead of a control rod, a connecting plate or the like can also be used. Another type of rigid connection between the drive lever and the lever arm can also be used. It is essential that the basic setting, i. H. adjust the inclination of the lever arm and a force application point can be varied.

Die Steuerstange umfaßt eine Verstellhülse 13, sowie an ihrem anderen Ende ein weiteres Anschlußauge 12, welches am Hebelarm 29 befestigt ist. Am freien Ende des Hebelarms 29 ist eine Laufrolle 15 angeordnet, die mit dem Unterstempel 16 zusammenwirkt. Der Unterstempel 16 ist durch eine Feder vorgespannt und wird von dem Hebelarm 29 auf und nieder bewegt.The machine for attaching rivets, push buttons or the like comprises a drive disk 1, which is in gear connection with a thrust crank disk 2. An eccentric disc 3 is arranged on the same shaft in a fixed connection with the thrust crank disc 2, the connection between the eccentric disc 3 and the thrust crank disc 2 being realized by a connecting screw 4. The connecting screw 4 is arranged in an elongated hole arranged in the sliding crank disk 2, so that the eccentric disk 3 can be adjusted with regard to the timing. The eccentric disc 3 is connected to a roller 5, which is arranged on a drive lever 6. The drive lever 6 has step adjustment holes 7. A lever arm 29, which is a two-arm lever that can be moved about a lever axis 11, is connected to the drive lever 6 by means of an articulated connection 10. In one of the step setting holes 7 on the drive lever 6, a connecting eye 12 of a control rod is attached. The control rod comprises an adjusting sleeve 13 and at its other end a further connecting eye 12 which is attached to the lever arm 29. At the free end of the lever arm 29, a roller 15 is arranged, which cooperates with the lower punch 16. The lower punch 16 is biased by a spring and is moved up and down by the lever arm 29.

Die Schubkurbelscheibe 2 steht in Verbindung mit einem Stößelwagen 18, wozu eine an der Schubkurbelscheibe 2 angeordnete Laufrolle 19 in einer Führungsbahn 20 des Stößelwagens 18 läuft. Die Führungsbahn 20 hat einen Radius, so daß sich eine Rastzeit in der hinteren Umkehrposition ergibt, bei welcher von der Laufrolle 19 keine Vorschubkräfte auf den Stößelwagen 18 übertragen werden, weil die Laufrolle 19 in der Führungsbahn 20 abläuft. Am Stößelwagen 18 sind Stößel 21 angeordnet, mit welchen die Artikel den Werkzeugen zum definierten Zeitpunkt zugeführt werden.The thrust crank disc 2 is connected to a tappet carriage 18, for which purpose a roller 19 arranged on the thrust crank disc 2 runs in a guideway 20 of the tappet carriage 18. The guide track 20 has a radius, so that there is a resting time in the rear reversing position, in which no feed forces are transmitted from the roller 19 to the ram 18 because the roller 19 runs in the guide track 20. Tappets 21 are arranged on the pusher carriage 18, with which the articles are fed to the tools at the defined point in time.

Die mit der Antriebsscheibe 1 verbundene Kurbelstange 22 betätigt einen Hebel 23, der um eine Achse bewegbar ist und an seinem anderen Hebelende eine Gelenkverbindung 24 aufweist, an welcher ein Verbindungshebel 25 befestigt ist. Am anderen Ende des Verbindungshebels 25 ist ein Stößel 26 angeordnet, an dessen unteren Ende der Oberstempel 27 befestigt ist. Im Bereich des Oberstempels 27 ist ein Haltewerkzeug 28 angeordnet.The crank rod 22 connected to the drive pulley 1 actuates a lever 23 which is movable about an axis and has at its other lever end an articulated connection 24 to which a connecting lever 25 is fastened. At the other end of the connecting lever 25, a plunger 26 is arranged, at the lower end of which the upper punch 27 is fastened. A holding tool 28 is arranged in the region of the upper punch 27.

Die Funktion einer derartigen Maschine ist an sich bekannt. Im Zusammenhang mit der vorliegenden Anmeldung ist von Bedeutung, daß die Steuerstange, gebildet durch die Anschlußaugen 12, 14, eine Gewindestange und die Verstellhülse 13, längsverstellbar ist, und darüber hinaus alternative Befestigungspunkte für das Anschlußauge 12 am Antriebshebel 6 angeordnet sind. Durch die Auswahl der jeweiligen Stufeneinstellungsbohrung für die Befestigung des Anschlußauges 12 wird der Kraftangriffspunkt variiert.The function of such a machine is known per se. In connection with the present application, it is important that the control rod, formed by the connecting eyes 12, 14, a threaded rod and the adjusting sleeve 13, is longitudinally adjustable, and that alternative fastening points for the connecting eye 12 are arranged on the drive lever 6.
