Abstract

Bei einer matrizenseitigen Auswerfvorrichtung für Pressen wirkt auf einem Pressengestell (14) eine stationäre Preßmatrize (120) mit einem Preßstempel zur Umformung eines in eine Bohrung der Preßmatrize (120) eingeführten Preßlings (136) zusammen. In einer Bohrung (110) im Pressengestell (14) ist verschiebbar ein Auswerferstift (112) vorgesehen, der unter Vorspannung gegen einen Auswerferhebel (32) angedrückt ist, der von einem Betätigungshebel (56) zwischen einer Ausgangsstellung, und einer Auswerf-Endstellung verschwenkbar ist und sich auf seiner dem Auswerferstift (112) abgewandten Seite in seiner Ausgangsstellung gegen ein Druckstück (44) am Pressengestell (14) abstützt.In the case of a die-side ejection device for presses, a press frame (14) acts on a stationary press die (120) with a press die for forming a Bore the press die (120) inserted compact (136) together. In a hole (110) an ejector pin (112) is slidably provided in the press frame (14) Preload is pressed against an ejector lever (32) by an actuating lever (56) between an initial position and an ejection end position is pivotable and on its side facing away from the ejector pin (112) in its starting position a pressure piece (44) is supported on the press frame (14).

Der Auswerferhebel (32) sitzt verschwenkbar auf einem Trageteil (20), das am Pressengestell (14) senkrecht zur Längsachse des Auswerferstiftes (112) und parallel zur Verschwenkebene des Betätigungshebels (56) zwischen zwei Anschlägen (50, 52) verfahrbar und zur Anlage an dem Druckstück (44) mit einer Formfläche (40) versehen ist, die gegen eine komplementäre Formfläche (46) am Druckstück (44) flächig anlegbar ist, wobei in der Ausgangsstellung des Auswerferhebels (32) auch bei einem Verfahren des Trageteils (20) an beiden Formflächen (40; 46) deren flächig-komplementäre Anlage erhalten bleibt.

Figure 00000001
The ejector lever (32) is pivotably seated on a support part (20) which can be moved on the press frame (14) perpendicular to the longitudinal axis of the ejector pin (112) and parallel to the pivoting plane of the actuating lever (56) between two stops (50, 52) and comes into contact with the system the pressure piece (44) is provided with a shaped surface (40) which can be placed flat against a complementary shaped surface (46) on the pressure piece (44), with the ejector lever (32) also in the initial position when the carrying part (20) is moved two shaped surfaces (40; 46) whose surface-complementary contact is preserved.
