Description
Die vorliegende Erfindung betrifft eine Radialpresse mit einer Grundstruktur und einem darin aufgenommenen Presswerkzeug, wobei die Grundstruktur zwei mittels einer Antriebseinheit relativ zueinander bewegbare Strukturelemente aufweist und das Presswerkzeug mehrere um eine Pressenachse herum angeordnete Pressbacken umfasst, die sich über jeweils zwei Gleitflächenanordnungen gleitend auf korrespondierenden, den Strukturelementen zugeordneten Gegenflächenanordnungen abstützen.The present invention relates to a radial press having a basic structure and a pressing tool accommodated therein, wherein the basic structure comprises two structural elements which are movable relative to each other by means of a drive unit and the pressing tool comprises a plurality of pressing jaws arranged around a press axis, which slidingly adjoin corresponding sliding surfaces via two respective sliding surface arrangements Support structure elements associated mating surface arrangements.
Derartige Radialpressen sind in verschiedenen Bauweisen bekannt, beispielsweise als Jochpresse, bei welcher die beiden als Pressenjoche ausgeführten Strukturelemente in einer auf der Pressenachse senkrecht stehenden Ebene relativ zueinander bewegbar sind (vgl. z.B.
Die bekannten gattungsgemäßen Radialpressen haben sich in der Praxis bewährt und genügen in aller Regel den an sie gestellten Anforderungen. Gleichwohl zielt die vorliegende Erfindung darauf ab, gattungsgemäße Radialpressen in dem Sinne weiter zu verbessern, dass die Präzision des hergestellten Werkstücks noch weiter gesteigert wird, insbesondere durch eine weiter verbesserte Reproduzierbarkeit und Maßhaltigkeit.The known generic radial presses have proven themselves in practice and generally satisfy the demands placed on them. Nevertheless, the present invention aims to further improve generic radial presses in the sense that the precision of the workpiece produced is further increased, in particular by a further improved reproducibility and dimensional accuracy.
Auf überraschend einfache Weise wird die vorstehend angegebene Aufgabenstellung dadurch gelöst, dass bei Radialpressen der eingangs angegebenen Art zumindest im Bereich jeweils einer der zusammenwirkenden Gleit- und Gegenflächenanordnungen die lastabtragende Abstützung der Pressbacken auf dem betreffenden Strukturelement in zwei zueinander beabstandeten Bereichen erfolgt, zwischen denen ein sich in Gleitrichtung der betreffenden Pressbacke relativ zu dem zugeordneten Strukturelement erstreckender Freiraum ohne lastabtragende Funktion befindet, wobei in den beiden lastabtragenden Bereichen der jeweiligen zusammenwirkenden Gleit- und Gegenflächenanordnungen die identische Gleitebene besteht. Es ist somit, mit anderen Worten, für erfindungsgemäße Radialpressen insbesondere und im Zusammenwirken mit den übrigen bestimmenden Merkmalen charakteristisch, dass jeweils in einer durch zusammenwirkende Gleit- und Gegenflächenanordnungen definierten Gleitebene nicht ein zusammenhängender lastabtragender Bereich vorliegt, sondern dass vielmehr in der jeweiligen Gleitebene die Lastabtragung von der betreffenden Pressbacke auf das jeweilige Strukturelement in zwei diskreten, zueinander beabstandeten Bereichen erfolgt, zwischen denen sich ein keine lastabtragende Funktion aufweisender Freiraum befindet, welcher sich in Gleitrichtung der betreffenden Pressbacke relativ zum zugeordneten Strukturelement erstreckt. Durch diese Maßnahme wird wirksam auch bei einer längeren Betriebsdauer der Radialpresse einer Formveränderung der Pressbacken, Grundbacken und/oder Gleitebene dergestalt, dass diese im Bereich der Gleitflächenanordnungen leicht ballig werden, entgegengewirkt. Auf diese Weise wird in weiterer Konsequenz verhindert, dass die Pressbacken kippeln, was bei herkömmlichen gattungsgemäßen Radialpressen insbesondere bei stark exzentrischen Belastungen Beeinträchtigungen hinsichtlich der Maßhaltigkeit des Werkstücks nach sich ziehen kann. Indem in Anwendung der vorliegenden Erfindung ein solches Kippeln der Pressbacken auch bei in erheblichem Maße exzentrischen Belastungen sicher vermieden wird, lassen sich mit solchen Radialpressen Werkstücke mit größtmöglicher Maßhaltigkeit herstellen.In a surprisingly simple manner, the above-mentioned object is achieved in that at radial presses of the type specified at least in each case one of the cooperating sliding and mating surface arrangements, the load-bearing support of the pressing jaws on the respective structural element in two spaced-apart areas, between which a in the sliding direction of the respective pressing jaw relative to the associated structural element extending free space without load-bearing function, wherein in the two load-bearing areas of the respective cooperating sliding and mating surface arrangements, the identical sliding plane consists. Thus, in other words, it is characteristic of radial presses according to the invention, in particular and in conjunction with the other determining features, that in each case a sliding plane defined by cooperating sliding and counter surface arrangements does not exist a contiguous load-bearing area is present, but rather that in the respective sliding plane the load transfer from the respective pressing jaw on the respective structural element in two discrete, spaced-apart areas, between which there is no load-carrying function having free space, which is in the sliding direction of the respective pressing jaw extends relative to the associated structural element. By this measure is effectively counteracted even with a longer service life of the radial press a change in shape of the pressing jaws, base jaws and / or sliding plane such that they are slightly spherical in the sliding surface arrangements. In this way, it is prevented in a further consequence that the pressing jaws tilt, which can cause adverse effects on the dimensional accuracy of the workpiece in conventional generic radial presses especially at highly eccentric loads. By reliably avoiding such tilting of the pressing jaws even when the load is eccentrically significant to a considerable extent, it is possible with such radial presses to produce workpieces of the greatest possible dimensional accuracy.
Eine erste bevorzugte Weiterbildung der vorliegenden Erfindung zeichnet sich dadurch aus, dass die Freiräume jeweils durch an den Pressbacken im Bereich der Gleitflächenanordnungen vorgesehene, sich in Gleitrichtung der betreffenden Pressbacke relativ zu dem zugeordneten Strukturelement erstreckende Aussparungen gebildet sind, welche an der jeweiligen Gleitflächenanordnung zwei räumlich getrennte, zueinander beabstandete koplanare Gleitflächenabschnitte definieren, zwischen denen die zugeordnete Aussparung verläuft. Dies stellt eine erste technisch-konstruktive Umsetzung des weiter oben dargelegten Konzepts der vorliegenden Erfindung dar. Diese Weiterbildung kann insbesondere bei solchen Radialpressen Anwendung finden, bei denen die Pressbacken sich direkt gleitend auf den beiden Strukturelementen abstützen, d.h. nicht unter Zwischenschaltung spezifischer gesonderter Gleitbleche.A first preferred development of the present invention is characterized in that the free spaces are each formed by recesses provided on the pressing jaws in the region of the sliding surface arrangements and extending in the sliding direction of the relevant pressing jaw relative to the associated structural element are, which define on the respective Gleitflächenanordnung two spatially separated, spaced-apart coplanar Gleitflächenabschnitte between which the associated recess extends. This represents a first technical-constructive implementation of the above-presented concept of the present invention. This development can be found in particular in such radial presses application, in which the pressing jaws are supported directly sliding on the two structural elements, ie not with the interposition of specific separate sliding plates.
Sind demgegenüber zwischen den Pressbacken und den Strukturelementen solche gesonderten Gleitbleche vorgesehen, so können - gemäß einer anderen bevorzugten Weiterbildung der Erfindung - die genannten Freiräume jeweils durch Aussparungen gebildet sein, die an den - auf dem betreffenden Strukturelement aufliegenden - Gleitblechen vorgesehen sind und sich in Gleitrichtung der betreffenden Pressbacke relativ zu dem zugeordneten Strukturelement erstrecken, wobei beidseits von den Aussparungen lastabtragende Bereiche bestehen, die sowohl an dem Strukturelement wie auch an der jeweiligen Pressbacke anliegen. Grundsätzlich können dabei die besagten Aussparungen jeweils an der Seite des Gleitblechs, mit der dieses an dem betreffenden Strukturelement aufliegt, oder an der gegenüber liegenden, der Pressbacke gegenüber stehenden Seite des Gleitblechs oder aber auch an beiden Seiten des Gleitblechs vorgesehen sein. Wo im Einzelfall die Aussparungen angeordnet sind, hat keine prinzipiellen Auswirkungen auf die Funktionsweise. Bei all diesen Ausgestaltungen kommt als Vorteil zum Tragen, dass im Falle einer möglichen Abnutzung die Gegenflächen (bei lagefest zu dem betreffenden Strukturelement angeordneten Gleitblechen) bzw. die Gleitflächen (bei lagefest zu den Pressbacken angeordneten Gleitblechen) durch Austausch der Gleitbleche mit geringem Aufwand erneuert werden können.If, on the other hand, such separate sliding plates are provided between the pressing jaws and the structural elements, then - according to another preferred development of the invention - said clearances can each be formed by recesses provided on the sliding elements - resting on the relevant structural element - and in the sliding direction extend the respective pressing jaw relative to the associated structural element, wherein on both sides of the recesses load-carrying regions exist, which abut both on the structural element as well as on the respective pressing jaw. In principle, said recesses may be respectively provided on the side of the sliding plate, with which this rests on the respective structural element, or on the opposite, the pressing jaw opposite side of the sliding plate or else on both sides of the sliding plate. Where arranged in individual cases, the recesses have no fundamental effect on the functioning. In all these embodiments comes as an advantage to support that in the event of possible wear, the mating surfaces (at fixed to the respective structural element arranged sliding plates) or the sliding surfaces (at fixed to the press jaws arranged sliding plates) are renewed by replacing the sliding plates with little effort can.
Die erfindungsgemäß vorgesehenen Freiräume können im Übrigen, im Sinne einer abermals anderen Weiterbildung der vorliegenden Erfindung, auch jeweils durch an dem Strukturelement im Bereich der Gegenflächenanordnungen vorgesehene, sich in Gleitrichtung der betreffenden Pressbacke relativ zu dem Strukturelement erstreckende Aussparungen gebildet sein, welche an der jeweiligen Gegenflächenanordnung zwei räumlich getrennte, zueinander beabstandete koplanare Gegenflächenabschnitte definieren, zwischen denen die zugeordnete Aussparung verläuft. In besonders gelagerten Fällen ist sogar denkbar, die Aussparungen, welche (die besagten Freiräume bildend) an den jeweiligen zusammenwirkenden Gleit- und Gegenflächenanordnungen die jeweils zwei koplanaren lastabtragenden Bereiche voneinander abgrenzen und auf diese Weise begrenzen, sowohl an den Pressbacken als auch an den Strukturelementen, sowohl an den Pressbacken als auch an möglichen Gleitblechen oder sowohl an den Strukturelementen als auch an möglichen Gleitblechen vorgesehen sind.The free spaces provided according to the invention can, moreover, in the sense of a yet further development of the present invention, also be formed by recesses provided on the structural element in the area of the counter-surface arrangements, extending in the sliding direction of the respective pressing jaw relative to the structural element, which recesses lie against the respective mating surface arrangement define two spatially separated, spaced apart coplanar mating surface portions between which the associated recess extends. In specially supported cases, it is even conceivable that the recesses (which form said free spaces) delimit and respectively delimit the two coplanar load-bearing regions from each other on the cooperating sliding and counter-surface arrangements, both on the pressing jaws and on the structural elements, are provided both on the pressing jaws and on possible sliding plates or on both the structural elements and on possible sliding plates.
Im Hinblick auf die vorstehend dargelegte Funktion der erfindungsgemäßen Radialpresse ist es besonders günstig, wenn die quer zu der Gleitrichtung der betreffenden Pressbacke relativ zu dem zugeordneten Strukturelement bestimmte Breite der Freiräume mindestens 15% der Summe der Breiten der beiden lastabtragenden Bereiche entspricht. Bei typischen Anwendungen ist es besonders vorteilhaft, wenn die Breite der Freiräume in diesem Sinne mindestens 35% der Summe der Breiten der beiden lastabtragenden Bereiche entspricht. Bei bestimmten Konstellationen kann sich sogar als zweckmäßig erweisen, dass die Breite der Freiräume mindestens 50% der Summe der Breiten der beiden lastabtragenden Bereiche entspricht.With regard to the above-described function of the radial press according to the invention, it is particularly advantageous if the width of the free spaces determined transversely relative to the sliding direction of the respective pressing jaw relative to the associated structural element corresponds to at least 15% of the sum of the widths of the two load-bearing areas. In typical applications, it is particularly advantageous if the width of the free spaces in this sense corresponds to at least 35% of the sum of the widths of the two load-bearing areas. In certain constellations, it may even prove expedient that the width of the free spaces corresponds to at least 50% of the sum of the widths of the two load-bearing areas.
Die erfindungsgemäßen Vorteile stellen sich bereits bei äußerst flachen Freiräumen ein. In diesem Sinne genügt bereits, wenn die Tiefe der Freiräume 0,5% von deren quer zu der Gleitrichtung der betreffenden Pressbacke relativ zu dem zugeordneten Strukturelement bestimmten Breite beträgt, wobei es hinsichtlich der Funktion nicht von Nachteil ist, wenn die Tiefe der Freiräume diesen Wert übersteigt, indem sie z.B. 1%, 2% oder einen noch größeren Anteil der Breite der Freiräume beträgt.The advantages according to the invention are already present in extremely shallow clearances. In this sense, it is sufficient if the depth of the free spaces is 0.5% of their transverse to the sliding direction of the respective pressing jaw relative to the associated structural element width, and it is not a disadvantage in terms of function, if the depth of the free spaces this value exceeds, for example by 1%, 2% or even more of the width of open spaces.
Im Interesse einer besonders hohen Qualität des aus der Radialverformung hervorgegangenen Werkstücks ist es im Sinne einer abermals anderen bevorzugten Weiterbildung der vorliegenden Erfindung günstig, wenn die beiden lastabtragenden Bereiche der jeweiligen zusammenwirkenden Gleit- und Gegenflächenanordnungen im wesentlichen die gleiche quer zu der Gleitrichtung der betreffenden Pressbacke relativ zu dem zugeordneten Strukturelement bestimmte Breite aufweisen. Dies ist deshalb besonders günstig, weil ein möglicher Verschleiß an den Pressbacken, den Strukturelementen und/oder möglichen Gleitblechen die jeweils zwei lastabtragenden Bereiche in jeder Gleitebene gleichermaßen betrifft, so dass sich ein solcher Verschleiß nicht nachteilig auf die Positionierung der Pressbacken relativ zu den Strukturelementen auswirkt.In the interest of a particularly high quality of the resulting from the radial deformation workpiece, it is favorable in terms of yet another preferred embodiment of the present invention, when the two Lastabtragenden areas of the respective cooperating sliding and mating surface arrangements substantially the same transverse to the sliding direction of the respective pressing jaw relative to the associated structural element determined width. This is particularly advantageous because a possible wear on the pressing jaws, the structural elements and / or possible sliding plates equally affects the two load-bearing areas in each sliding plane, so that such wear does not adversely affect the positioning of the pressing jaws relative to the structural elements ,
Anwenden lässt sich die vorliegende Erfindung auf alle bekannten Bauarten von Radialpressen, insbesondere sowohl auf Jochpressen wie auch auf Hohlkolben- und Druckplattenpressen. Bei einer Jochpresse mit zwei als Pressenjoche ausgeführten, quer zur Pressenachse relativ zueinander bewegbaren Strukturelementen erstrecken sich die erfindungsgemäß vorgesehenen Freiräume - gemäß der Bewegungsrichtung der Pressbacken bezogen auf die Pressenjoche - relativ zur Pressenachse in Umfangsrichtung. Bei Hohlkolben- oder Druckplattenpressen mit zwei in Richtung der Pressenachse relativ zueinander bewegbaren Strukturelementen erstrecken sich die erfindungsgemäß vorgesehenen Freiräume demgegenüber - gemäß der entsprechenden Gleitbewegung der Pressbacken bezogen auf die Strukturelemente - in axialen Ebenen.Apply the present invention to all known types of radial presses, in particular both on yoke presses as well as on hollow piston and pressure plate presses. In the case of a yoke press with two structural elements designed as press yokes and movable relative to one another transversely to the press axis, the free spaces provided according to the invention extend in the circumferential direction relative to the press axis, in accordance with the direction of movement of the press jaws relative to the press yokes. In the case of hollow piston or pressure plate presses with two structural elements which are movable relative to one another in the direction of the press axis, the free spaces provided according to the invention, in contrast, extend in axial planes according to the corresponding sliding movement of the pressing jaws relative to the structural elements.
