Description

Die Erfindung bezieht sich auf eine Werkzeugwechselein­richtung bei Rundhämmer- und Knetmaschinen nach dem Ober­begriff des Anspruchs 1.The invention relates to a tool changing device in rotary hammers and kneaders according to the preamble of claim 1.

Es sind Rundhämmer- und Knetmaschinen bekannt, die nach dem Vorschub- oder Einstechverfahren arbeiten, mit zwei oder mehreren Hämmerstößeln und -backen als Umformwerk­zeuge in einer Werkzeugführung mit Frontdeckel, insbeson­dere mit Backenzustellung durch Keileinschub. Bei diesen Maschinen erfolgt bisher der Wechsel der Hämmerbacken von Hand, was umständlich und zeitraubend ist und einer ratio­nellen Arbeitsweise entgegensteht, insbesondere dann, wenn es sich um kleinere Serien handelt, was ein öfteres Um­stecken der Werkzeuge erfordert, oder für die Bearbeitung von Werkstücken mit mehreren Abstufungen.Rotary hammers and kneaders are known which operate according to the feed or plunge method, with two or more hammer plungers and jaws as forming tools in a tool guide with a front cover, in particular with jaw feed by wedge insertion. With these machines, the hammer jaws have so far been changed by hand, which is cumbersome and time-consuming and prevents efficient operation, especially when it comes to smaller series, which requires the tools to be repositioned more often, or for machining workpieces with several Gradations.

Es ist Aufgabe der Erfindung, eine Werkzeugwechseleinrich­tung speziell für Rundhämmer- und Knetmaschinen zu schaf­fen, deren Besonderheiten neuer, erfinderischer Lösungs­wege bedürfen.It is an object of the invention to provide a tool changing device especially for rotary hammers and kneaders, the special features of which require new, inventive solutions.

Zur Lösung dieser Aufgabe kennzeichnet sich erfindungsge­mäß die Werkzeugwechseleinrichtung bei Rundhämmer- und Knetmaschinen nach dem Oberbegriff von Anspruch 1 gemäß der Erfindung dadurch, daß ein Schwenk- oder Hubsegment mit nebeneinander angeordneten Aufnahmekammern mit Werkzeug­greifer und -halter für die auswechselbaren Werkzeug­sätze - Hämmerbacken - in die Werkstückzubringerachse zum Werkzeugwechsel schwenk- oder schiebbar ist, welches Schwenk- oder Hubsegment eine Führungsbahn aufweist, in welche der ebenfalls verschwenk- oder verschiebbar ange­ordnete Frontdeckel eingreift, derart, daß er in der Ar­beitsstellung das Hämmerwerk abdeckt und in der Werkzeug­wechselstellung freigibt.To solve this problem, the tool changing device in rotary hammers and kneaders according to the invention is characterized in that a swivel or lifting segment with juxtaposed receiving chambers with tool grippers and holders for the interchangeable tool sets - hammer jaws - in the workpiece feeder axis is pivotable or slidable for tool change, which swivel or lifting segment has a guideway into which the front cover, which is likewise pivoted or slidably engages, in such a way that it covers the hammer mechanism in the working position and releases it in the tool changing position.

Im einzelnen sind hierzu den Werkzeuggreifern und -haltern der Aufnahmekammern im Schwenk- oder Hubsegment senkrecht hierzu verschwenkbare Betätigungsarme zugeordnet, welche die ausgewählten Werkzeugsätze - Hämmerbacken - nach Einstel­lung auf die Werkstückzubringerachse von der Werkzeug­führung in die entsprechende Aufnahmekammer ein- bzw. aus­bringen.In particular, the tool grippers and holders of the receiving chambers in the swivel or lifting segment are assigned vertically pivotable actuating arms which insert or remove the selected tool sets - hammer jaws - from the tool guide into the corresponding receiving chamber after adjustment to the workpiece feeder axis.

Weitere Einzelheiten der Werkzeugwechseleinrichtung bei Rundhämmer- und Knetmaschinen gemäß der Erfindung sind in der Zeichnung anhand eines bevorzugten Ausführungsbeispiels dargestellt und nachfolgend beschrieben.Further details of the tool changing device in rotary hammers and kneaders according to the invention are shown in the drawing using a preferred embodiment and described below.
