Description
In dem Patent 312504 ist eine Einrichtung zum Bewegen von Einzelmotoren /betriebener Stempel zum Anpressen von Werkstücken beschrieben, bei welcher die Einzelmotoren gemeinsam abgeschaltet werden, wenn alle Motoren einen gleichmäßigen Druck ihrer Stempel herbeigeführt haben. In den dort beschriebenen Ausführungsbeispielen war als Maß für den ausgeübten Druck die Stromstärke in den Motoren benutzt, die durch Höchststromrelais das Abschalten des Einschaltschützes herbeiführt.In patent 312504 there is a device for moving single motors / operated punches for pressing workpieces described in which the individual motors are switched off together if all Motors have brought about an even pressure on their stamps. In there The exemplary embodiments described was the current strength as a measure of the pressure exerted used in the motors that switch off the switch-on contactor through high-current relays brings about.
Nach der Erfindung wird zum Umschalten des den Schützstromkreis beherrschenden Schalthebeis eine mechanisch wirkende Vorrichtung verwendet, die darin besteht, daß als Maß für den Druck der Stempel eine starke Feder dient, von deren räumlicher Zusammenpressung die Bewegung des Schalthebels abhängig gemachtest. According to the invention, the switching lever controlling the contactor circuit is switched over a mechanically acting device is used, which consists in that a strong spring as a measure of the pressure of the stamp serves, on whose spatial compression the movement of the shift lever is made dependent.
In der Figur ist eine solche Anordnung dargestellt. Der Preßstempel 11 ist mit der Spindel 15 nicht starr, sondern unter Vermittlung einer starken Feder 34 verbunden.Such an arrangement is shown in the figure. The ram 11 is with the Spindle 15 is not rigid, but rather connected by means of a strong spring 34.
An dem Stempel ist ein Führungsstift 44 befestigt, der mittels eines Bundes 54 den Arm 64 des Schalthebels 31 umlegt, sobald die Feder 34 zusammengepreßt wird. Durch eine Feder 74 am Stift 44 wird der Arm 64 dauernd gegen den Bund gepreßt, so daß beim Nachlassen des Druckes auf den Preßstempel 11 der Schalthebel 31 wieder die oberen Kontakte berührt, die den Stromkreis des Einschaltschützes geschlossen halten.A guide pin 44 is fastened to the stamp, which by means of a collar 54 supports the arm 64 of the shift lever 31 flips over as soon as the spring 34 is compressed. By a spring 74 on the pin 44, the arm 64 is constantly pressed against the collar, so that when it slackens the pressure on the ram 11 of the switching lever 31 again the upper contacts that keep the circuit of the closing contactor closed.
