Claims (4)

  1. Biegemaschine zum Biegen einer Platte aus preßbarem Material, die eine Blechhalteeinrichtung (4) umfaßt, die die Platte (1) fest in der horizontalen Ebene zwischen der Blechhalteeinrichtung und einem entsprechenden Amboß (2) hält, und ein messerförmiges Werkzeug (11), das den Biegevorgang ausführt, wobei das Werkzeug (11) eine erste Biegephase durch eine reine Verschiebungsbewegung ausführen kann, und eine zweite Biegephase durch eine kombinierte Verschiebungs-Dreh-Bewegung, wobei in der ersten Biegephase der Kantenabschnitt der Platte um einen Winkel von 90° gebogen wird, und in der zweiten Biegephase der Biegewinkel auf einen beliebigen Winkel über 90° vergrößert wird, und die einen Betätigungskolben (3) umfaßt, der über eine weitere Stange (5a) mit der Blechhalteeinrichtung (4) verbunden ist, die Bewegung des Kolbens (3) nur senkrecht zu der Blechhalteeinrichtung ermöglicht, dadurch gekennzeichnet, daß
    - das messerförmige Werkzeug (11) starr mit einem Betätigungshebel (11a) verbunden ist, der sich auf einer Stange (10) dreht, deren Position in bezug auf den Betätigungskolben (3) feststehend ist,
    - sich der Hebel (11a) in einen Zwischenraum zwischen dem Kolben und der Blechhalteeinrichtung (4) hinein erstreckt,
    - der Hebel durch Kontakt des Kopfes eines Bolzens (6), der an der Blechhalteeinrichtung oder dem Hebel angebracht ist, mit dem Hebel bzw. der Blechhalteeinrichtung betätigt wird.
  2. Biegemaschine nach Anspruch 1, dadurch gekennzeichnet, daß eine erste Feder (5) vorhanden ist, die den Kolben (3) elastisch von der Blechhalteeinrichtung (4) getrennt hält, und eine zweite Feder (14) vorhanden ist, die den Kolben (3) von dem Abschnitt des Hebels, der dem Anbringungsteil des messerförmigen Werkzeugs gegenüberliegt, elastisch getrennt hält.
  3. Biegemaschine nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, daß das messerförmige Werkzeug (11) mit einer Unterseite (12) versehen ist, die im wesentlichen flach ist, und sein Ende (13), das der Blechhalteeinrichtung zugewandt ist, einen spitzen Winkel aufweist.
  4. Biegemaschine nach Anspruch 3, dadurch gekennzeichnet, daß der Abstand zwischen der Unterseite (12) und der Platte (1) kleiner ist als der Abstand zwischen entsprechenden Kontaktpunkten an dem Kopf (7) des Bolzens (6) und dem Gegenlager (8) des Hebels (11a), wenn sich der Betätigungskolben (3) in der höchstmöglichen Stellung befindet.
