Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Zum Pressen pulverförmiger Masse ist es in der Regel notwendig, zwischen einem schwächeren Vordruck und dem Hauptdruck den Stempel etwas zurückgehen zu lassen, damit die eingepreßte Luft entweichen kann. Auch beim Prägen, Stanzen usw. kommt es vor, daß ein zwei- oder mehrmaliger Druck ausgeübt werden muß. Der dabei durch die Änderung der Umdrehungsrichtung der Spindel entstehende Zeitverlust wird durch nachstehend beschriebene Erfindung beseitigt, indem die Unterbrechung der Druckbewegung und das Anheben des Stempels zwecks Entlüftung während der gleichen Umdrehungsrichtung der Spindel selbsttätig erfolgt.For pressing powdery mass it is usually necessary between one to let the stamp go back a little with the weaker pre-print and the main print, so that the compressed air can escape. It also happens when embossing, punching, etc. suggests that two or more pressures must be applied. The through the Changing the direction of rotation of the spindle resulting in loss of time is caused by the following Invention described eliminated by interrupting the printing movement and lifting the ram for the purpose of venting during the same direction of rotation the spindle takes place automatically.

Auf der Zeichnung ist die Erfindung dargestellt. The invention is shown in the drawing.

An dem unteren Ende α der Spindel b ist die Druckfläche mit Erhöhungen versehen, und in gleicher Weise der in dem Gleitstück c befindliche Amboß d (Gesperre). Sobald die höchsten Punkte des Spindelendes und die höchsten Punkte des Ambosses übereinanderstehen, findet der erste Druck statt. Bei weiterer Umdrehung der Spindel entsteht ein Zwischenraum zwischen den Druckflächen, und das Gleitstück c mit Stempel f steht still oder wird durch Federn e gehoben. Inzwischen hat sich die weiter drehend abwärts bewegte Spindel mit ihrer Druckfläche wieder voll auf diejenige des Ambosses gelegt, und es erfolgt der Hauptdruck.At the lower end α of the spindle b , the pressure surface is provided with elevations, and in the same way the anvil d (locking mechanism) located in the slider c. As soon as the highest points of the spindle end and the highest points of the anvil are on top of one another, the first pressure takes place. With further rotation of the spindle, a gap is created between the pressure surfaces, and the slider c with punch f stands still or is lifted by springs e. In the meantime, the spindle, which continues to rotate downwards, has again placed its pressure surface fully on that of the anvil, and the main pressure is applied.

Claims (1)

Patent-Anspruch:Patent claim: Einrichtung an Spindelpressen mit einem zwischen Spindel und Gleitstück eingeschalteten Gesperre, dadurch gekennzeichnet, daß bei der stetigen Abwärtsbewegung der Spindel durch das Gleitstück (c) zunächst ein Vordruck ausgeübt wird, dann das Gesperre (α, d) sich löst, so daß der Preßvorgang -unterbrochen wird, während darauf nach wiedererfolgtem Eingriff des Gesperres der Hauptpreßdruck ausgeübt wird.Device on screw presses with a locking mechanism connected between the spindle and the slider, characterized in that during the steady downward movement of the spindle by the slider (c), first a form pressure is exerted, then the locking mechanism (α, d) is released so that the pressing process - is interrupted, while the main pressure is applied after the locking mechanism has re-engaged.
