Abstract
Description
Die Erfindung betrifft eine Anspitzschälmaschine, insbesondere zur Herstellung von Ziehangeln an Draht- oder Stangenenden aus Rund- oder Mehrkantmaterial als Vorbereitung des Ziehvorgangs, wobei das Material durch einen rotierenden Messerkopf reduziert wird. Durch eine geeignete Einrichtung wird erreicht, daß das Material direkt vor dem Messerkopf spielfrei und unter Vorspannung mit zwei oder mehr Rollen geführt wird, wobei die Querschnittsfläche der Führungsöffnung ohne Werkzeugwechsel stufenlos zwischen dem maximalen und dem minimalen Wert variiert werden kann.The invention relates to a pointed peeling machine, in particular for the production of Drawbars on wire or rod ends made of round or polygonal material as Preparation of the drawing process, the material being rotated by a Cutter head is reduced. A suitable device ensures that Material directly in front of the cutter head without play and under tension with two or more rollers is guided, the cross-sectional area of the guide opening without Tool change continuously between the maximum and the minimum value can be varied.
Bei nach dem Stande der Technik bekannten Anspitzschälmaschinen (Anspitzdrehmaschine, Anspitzfräsmaschine) befinden sich zwei oder mehr Drehmeißel in einem rotierenden Messerkopf und ein frei aus einem Spannstock herausragendes Draht- oder Stangenende wird im Zentrum des Messerkopfes zugeführt. Durch die Vorschubbewegung des Messerkopfes oder des Spannstocks wird die Durchmesserreduzierung des Drahtes oder der Stange bewirkt. Die Führung des frei auskragenden Draht- oder Stangenanfangs übernimmt eine Führungspatrone, die direkt vor dem Messerkopf angeordnet ist, oder das anzuspitzende Material wird direkt in den Messerkopf eingeführt, was jedoch nur sehr kurze Anspitzlängen zuläßt. Die Führungspatrone hat das jeweilige Profil des anzuspitzenden Materials und muß für jeden Materialdurchmesser ausgewechselt werden. Durch das erforderliche Spiel zwischen Führungspatrone und Draht- oder Stangenmaterial kann dieses radial entsprechend des Spiels ausweichen ebenso wie es sich durch die auftretenden Schnittkräfte verdrehen kann. Durch diese Beanspruchung des frei auskragenden Materials kommt es zu Ratterschwingungen, die zu Rattermarken auf dem angespitzten Material und zum Ausbrechen der Schälwerkzeuge führen.In pointed peeling machines known from the prior art (Pointed lathe, pointed milling machine) there are two or more Lathe tools in a rotating cutter head and one freely from a vice protruding wire or rod end is in the center of the cutter head fed. Through the feed movement of the cutter head or the vice the diameter of the wire or rod is reduced. The The free cantilevered wire or rod start is guided by one Guide cartridge, which is arranged directly in front of the cutter head, or that material to be sharpened is inserted directly into the cutter head, but only allows very short tip lengths. The guide cartridge has the respective profile of the material to be sharpened and must be replaced for each material diameter will. Due to the required play between the cartridge and wire or Bar material can dodge this radially according to the game as well it can twist due to the cutting forces that occur. Through this When the cantilevered material is subjected to stress, chatter vibrations occur. to chatter marks on the sharpened material and to break out the Guide peeling tools.
Sinn der Erfindung ist es, das anzuspitzende Material spielfrei und unter Vorspannung zu führen, um das während des Anspitzvorgangs auftretende radiale Ausweichen und die Torsionsbeanspruchung des anzuspitzenden Materials vollständig zu vermeiden und die Führungsöffnung ohne Werkzeugwechsel stufenlos zu variieren. The purpose of the invention is to free the material to be sharpened and under To lead to the radial occurring during the sharpening process Dodge and the torsional stress on the material to be sharpened to be avoided completely and the guide opening is stepless without changing tools to vary.
Zur Lösung dieser Aufgabe schlägt die Erfindung vor, daß der frei auskragende Draht- oder Stangenanfang in einer Lünette mit mindestens zwei Führungsrollen (3), wie in Fig. 1 dargestellt, spielfrei geführt wird. Die Führungslünette ist so gebaut, daß sie einen minimalen Abstand zwischen dem Messerkopf (7) und den Führungsrollen (3), wie in Fig. 2 dargestellt, während des gesamten Schälprozesses ermöglicht. Die Führungsrollen (3) sind in Schiebern (2) gelagert, die in einem Rahmen (1) beweglich angeordnet sind, so daß sie zwischen einem maximalen und einem minimalen Durchmesserwert variiert werden können.To achieve this object, the invention proposes that the freely projecting wire or rod start is guided in a steady rest with at least two guide rollers ( 3 ), as shown in FIG. 1, without play. The guide steady is constructed so that it allows a minimal distance between the cutter head ( 7 ) and the guide rollers ( 3 ), as shown in Fig. 2, during the entire peeling process. The guide rollers ( 3 ) are mounted in slides ( 2 ) which are movably arranged in a frame ( 1 ) so that they can be varied between a maximum and a minimum diameter value.
Ebenfalls zur Lösung dieser Aufgabe schlägt die Erfindung, ausgehend von einer Führungslünette der eingangs genannten Art, vor, daß jeder Schieber (2), wie in Fig. 1 und Fig. 2 dargestellt, in einem Rahmen (1) gelagert wird, wobei eine weitgehend gleiche Durchmessereinstellung der Schieber (2) dadurch erreicht wird, daß diese über in Schlitzen (4) verschiebbare Kulissensteine (5) mit einer drehbar gelagerten Scheibe (6) verbunden sind. Die Verbindung der Schieber (2) mit der drehbar gelagerten Scheibe (6) läßt nur weitgehend gleichzeitige Bewegungen der Schieber (2) zu. Es spielt hierbei keine Rolle, ob die drehbar gelagerte Scheibe (6) kraft- oder druckmittelbeaufschlagt angetrieben wird, oder ob mindestens einer der Schieber (2) kraft- oder druckmittelbeaufschlagt angetrieben wird, um eine weitgehend gleiche Durchmesserverstellung der Schieber (2) zu erreichen.To solve this problem, the invention proposes, starting from a guide bezel of the type mentioned, that each slide ( 2 ), as shown in Fig. 1 and Fig. 2, is mounted in a frame ( 1 ), one largely The same diameter setting of the slide ( 2 ) is achieved in that they are connected to a rotatably mounted disc ( 6 ) via sliding blocks ( 5 ) which can be moved in slots ( 4 ). The connection of the slide ( 2 ) with the rotatably mounted disc ( 6 ) allows only largely simultaneous movements of the slide ( 2 ). It does not matter whether the rotatably mounted disc ( 6 ) is driven by force or pressure medium, or whether at least one of the slides ( 2 ) is driven by force or pressure medium in order to achieve a largely identical diameter adjustment of the slider ( 2 ).
Als weitere Lösung dieser Aufgabe schlägt die Erfindung, ausgehend von einer Führungslünette der eingangs genannten Art, vor, daß jeder Schieber (2), wie in Fig. 1, Fig. 2 und Fig. 3 dargestellt, derart in einem Rahmen (1) gelagert wird, daß sich die Führungsfläche der Rollen (3) mit dem Durchmesserwert verändert. Dieses ermöglicht zum einen, daß Material mit einem großen Durchmesser eine große Führung durch breite Rollen (3) erhält, zum anderen besteht aber auch die Möglichkeit, die breiten Führungsrollen (3) bis auf einen minimalen Durchmesserwert einzustellen, wobei die Führungsfläche der Rollen (3) kontinuierlich abnimmt. Dieses ermöglicht eine spielfreie Führung des Materials zwischen dem maximalen und dem minimalen Durchmesserwert, wobei sich der Durchmesser der Führungsöffnung stufenlos variieren läßt.As another solution to this problem the invention proposes, starting from a front rest of the initially stated type, in that each slide (2), as shown in Fig. 1, Fig. 2 and Fig FIG. 3, so mounted in a frame (1) is that the guide surface of the rollers ( 3 ) changes with the diameter value. This allows on the one hand that the material is obtained with a large diameter, a large guide by wide rollers (3), on the other hand there is also the possibility of the wide guide rollers (3) up to a minimum diameter value set, wherein the guide surface of the rollers (3 ) decreases continuously. This enables the material to be guided without play between the maximum and the minimum diameter value, the diameter of the guide opening being able to be varied continuously.
