Patentanspruch:Claim: Scherpresse zum gratfreien Stanzschneiden mit gegenüberliegenden Werkzeugen, die auf gegeneinander beweglichen Werkzeugträgern angeordnet sind und von denen eines mit einem Vorsprung und das andere mit einer glatten Oberfläche verseben ist, wobei beim Schervorgang das Werkzeug mit dem Vorsprung in das Ausgangsmaterial eindringt und dann das Werkstück durch einen Abbrechstempel vom Ausgangsmaterial getrennt wird, dadurch gekennzeichnet, daß der Abbrechstempel im Pressenoberteil über elastisches Material eingepaßt bzw. abgestützt ist.Shear press for burr-free punch cutting with opposing tools that work against each other movable tool carriers are arranged and one of which has a projection and the other is sabotaged with a smooth surface, with the shearing process the The tool with the projection penetrates the starting material and then the workpiece through a break-off punch is separated from the starting material, characterized in that, that the break-off punch is fitted or supported in the upper part of the press by means of elastic material. Die Erfindung betrifft eine Scherpresse zum gratfreien Stanzschneiden mit gegenüberliegenden Werkzeugen, die auf gegeneinander beweglichen Werkzeugträgern angeordnet sind und von denen eines mit (inem Vorsprung und das andere mit einer glatten Oberfläche versehen ist, wobei beim Schervorgang das Werkzeug mit dem Vorsprung in das Ausgangsmaterial eindringt und dann das Werkstück durch einen Abbrechstempel vom Ausgangsmaterial getrennt wird.The invention relates to a shear press for burr-free punch cutting with opposing tools, which are arranged on mutually movable tool carriers and one of them with (one protrusion and the other is provided with a smooth surface, whereby during the shearing process the tool with the projection penetrates into the starting material and then through the workpiece a break-off punch is separated from the starting material. Bei derartigen Scherpressen ist es üblich, den Abbrechstempel im Pressenoberteil mittels hydraulischer Flüssigkeit, die zu seiner Betätigung dient, abzustützen (deutsche Patentschrift 371 004).
Der Erfindung liegt die Aufgabe zugrunde, eineIn shear presses of this type, it is customary to support the break-off punch in the upper part of the press by means of hydraulic fluid which is used to actuate it (German patent 371 004).
The invention is based on the object of a ίο einfache, wartungsfreie und selbsttätige Betätigungsvorrichtung für den Abbrechstempel von Scherpressen der eingangs genannten Art zu schaffen, bei denen die Länge des vom Abbrechstempel zurückzulegenden Weges kurz ist.ίο simple, maintenance-free and automatic actuation device to create for the break-off punch of shear presses of the type mentioned, in which the length of the path to be covered by the break-off stamp is short. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Abbrechstempel im Pressenoberteil über elastisches Material eingepaßt bzw. -abgestützt ist.
Als elastisches Material kann Gummi verwendet werden oder ein anderer geeigneter Werkstoff, wie z. B. Stahl in Form einer Feder.This object is achieved according to the invention in that the break-off punch is fitted or supported in the upper part of the press by means of elastic material.
Rubber can be used as the elastic material or another suitable material, such as, for. B. Steel in the form of a spring. Die mit der Erfindung erzielten Vorteile bestehen im wesentlichen darin, daß auf die sonst für die Betätigung des Abbrechstempels erforderliche hydraulisehe Einrichtung verzichtet werden kann, womit sich die Gesamteinrichtung und Bedienung der Scherpresse vereinfacht.The advantages achieved by the invention are essentially that on the otherwise for the actuation of the break-off punch required hydraulic device can be dispensed with, which simplifies the overall setup and operation of the shear press.
