Definitions
- the invention relates to a method for producing an at least partially elastically compressible clamping area which forms a section of a pin-shaped element and which is provided for the non-positive fixing of the element in a bore, the clamping area being divided by dividing the element into at least two legs their two ends are connected to each other, and an increase in the distance between these two legs is obtained.
- Such a method is known from GB-PS 1 149 332.
- the element is first pressed flat in the 'clamping area.
- the flattened section is then provided with a slot, so that there are two legs connected at their two ends in the flattened section of the element.
- the legs are rounded on the outside in order to adapt the outer contour of the legs to the curvature of the bore provided for receiving the element.
- This adaptation of the outer contour of a clamping area to the rounding of a hole into which the element is inserted is necessary so that, for. B. a surface metallization of the hole can not be damaged by inserting the element.
- Such elements form e.g. B. with a section to be inserted into the holes of a circuit board contact pins, contact blades or contact springs, which are combined in multi-pin, knife or contact spring strips.
- the object of the present invention is therefore to develop a method of the type mentioned at the outset such that the clamping region can be produced in as little as possible in one operation while maintaining its full functionality, in particular by creating an outer contour adapted to the bore rounding.
- this object is achieved in that the division of the element into two legs by means of two wedges which can be moved in opposite directions with wedge edges aligned parallel to the longitudinal axis of the element and having a wedge angle of approximately 30 ° to 60 ° is carried out in such a way that either the wedges are pressed into the element at the same time, with a slight offset of the wedge-shaped cutting edges, or that the wedges are pressed into the element one after the other with wedge-shaped edges aligned with one another, with appropriate support of the element on the opposite side, and that when the wedges are pressed into the Element evasive legs are intercepted transversely to the direction of movement of the wedges through the bore rounded abutment.
- the abutments provided transversely to the direction of movement of the wedges or chisels are designed to be resilient, so that the profile of the branches is not changed when the flat wire piece is divided. A profile change of the branches is made only in a separate second pressing process.
- FIGS. 1 to 4 it can be seen from FIGS. 1 to 4 that the incorporation of a clamping area into a pin-shaped element 1 which has a square cross section (the cross section of the element can of course also be round, oval, rectangular or polygonal) with the aid of two wedges 2, 3 is made, the wedge edges 4 have an angle of 60 °.
- the wedge edges 4 are directed parallel to one another and to the axis 5 of the element.
- the wedges 2, 3 can either as shown in Figures 1 and 2, simultaneously or, as can be seen from Figures 3 and 4, in succession which are moved into element 1. If the wedges 2, 3 are to be simultaneously moved into the element with their wedge edges 4 moving in opposite directions, it is necessary, as can be seen from FIGS. 1 and 2, the planes of motion 6 of the wedges 2, 3 against one through the axis 5 of the element 1 extending plane of symmetry 7 of the element 1 so that, as can be seen in particular from FIG. 2, the two wedges 2, 3 in their end position reached after dividing the element 1 into two legs 8 with their wedge edges 4 overlap each other.
- the legs 8 are increasingly moved apart.
- this movement is limited by two abutments 9, which are designed on their sides facing the element 1 as half-shells 10, which are adapted to the rounding of the bore into which the element 1 is to be inserted.
- the legs 8 are pressed with their outer side 11 facing away from the axis 5 of the element 1 by the wedges 2, 3 against the curves 10 of the abutment 9 and thereby adapted to these curves.
- the element therefore has a cross section in the clamping area, cf. 6 and 7, in which each of the two legs 8 has an outer face 11 adapted to the rounding of the bore and a wedge-shaped inner face 12 facing the opposite leg, so that the space 13 separating the legs 8 is formed like a butterfly.
- the wedges 2, 3 are successively moved into the element 1, cf. 3 and 4, the wedges 2, 3 with their planes of movement, which coincide with the planes of symmetry of the wedge cutting edges 4, can be aligned with a plane of symmetry 7 of the element 1 running through the axis 5 of the element.
- the shaping of the outside 11 of the legs 8 is also carried out when the wedges 2, 3 are successively pressed into the element 1 in the same way as in the method according to FIGS. 1 and 2 with the aid of two abutments 9.
- a plurality of clamping areas 15 can also be incorporated into an element 1 in the direction in which the element extends, the clamping action of the successive clamping areas 15 advantageously being offset from one another by 90 °.
- Fig. 8 From Fig. 8 it can be seen that the wedges 2, 3 run with their wedge edges 4 to the connection points 16 of the legs 8 each beveled, so that the legs 8 from a central portion 17 in which the legs 8 parallel to each other run at a certain distance from one another and thus form the actual clamping area, continuously approach each other again, that is to say run together.
- the element 11 In this area 1, the element 11 has a contour that is optimally matched to the bore due to the outside 11 of the legs 8 adapted to the rounding of the bore.

Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines wenigstens teilweise elastisch zusammen drückbaren Klemmbereiches, der einen Abschnitt eines stiftförmigen Elementes bildet und der zur kraftschlüssigen Fixierung des Elementes in einer Bohrung vorgesehen ist, wobei der Klemmbereich durch Aufteilung des Elementes in wenigstensezwei Schenkel, die an ihren beiden Enden miteinander verbunden sind, und eine Vergrößerung des Abstandes dieser beiden Schenkel voneinander erhalten wird.The invention relates to a method for producing an at least partially elastically compressible clamping area which forms a section of a pin-shaped element and which is provided for the non-positive fixing of the element in a bore, the clamping area being divided by dividing the element into at least two legs their two ends are connected to each other, and an increase in the distance between these two legs is obtained.
Ein solches Verfahren ist aus der GB-PS 1 149 332 bekannt. Bei dem bekannten Verfahren wird das Element zunächst im' Klemmbereich flach gedrückt. Anschließend wird der flachgedrückte Abschnitt mit einem Schlitz versehen, so daß sich zwei an ihren beiden Enden miteinander verbundene Schenkel in dem flachgedrückten Abschnitt des Elementes ergeben. Schließlich werden die Schenkel außen abgerundet, um die Außenkontur der Schenkel der Rundung der zur Aufnahme des Elementes vorgesehenen Bohrung anzupassen. Diese Anpassung der Außenkontur eines Klemmbereiches an die Rundung einer Bohrung, in die das Element eingesteckt wird, ist erforderlich, damit z. B. eine Oberflächenmetallisierung der Bohrung nicht durch das Einstecken des Elementes beschädigt werden kann.Such a method is known from GB-PS 1 149 332. In the known method, the element is first pressed flat in the 'clamping area. The flattened section is then provided with a slot, so that there are two legs connected at their two ends in the flattened section of the element. Finally, the legs are rounded on the outside in order to adapt the outer contour of the legs to the curvature of the bore provided for receiving the element. This adaptation of the outer contour of a clamping area to the rounding of a hole into which the element is inserted is necessary so that, for. B. a surface metallization of the hole can not be damaged by inserting the element.
Derartige Elemente bilden z. B. die mit einem Abschnitt in die Bohrungen einer Leiterplatte einzusteckenden Kontaktstifte, Kontaktmesser oder Kontaktfedern, die in vielpoligen Stift-, Messer- oder Kontaktfederleisten zusammengefasst sind.Such elements form e.g. B. with a section to be inserted into the holes of a circuit board contact pins, contact blades or contact springs, which are combined in multi-pin, knife or contact spring strips.
Es ist dabei erwünscht, den Klemmbereich auf möglichst rationelle Weise herstellen zu können und mit möglichst wenig Fertigungsschritten auszukommen.It is desirable to be able to produce the clamping area in the most rational manner possible and to get by with as few manufacturing steps as possible.
Aufgabe vorliegender Erfindung ist es daher, ein Verfahren der eingangs genannten Art so weiterzubilden, daß der Klemmbereich unter Aufrechterhaltung seiner vollen Funktionstüchtigkeit, insbesondere unter Schaffung einer der Bohrungsrundung angepaßten Außenkontur, in möglichst nur einem Arbeitsgang hergestellt werden kann.The object of the present invention is therefore to develop a method of the type mentioned at the outset such that the clamping region can be produced in as little as possible in one operation while maintaining its full functionality, in particular by creating an outer contour adapted to the bore rounding.
Erfindungsgemäß ergibt sich die Lösung dieser Aufgabe dadurch, daß die Aufteilung des Elementes in zwei Schenkel durch zwei gegensinnig zueinander bewegbare Keile mit parallel zur Längsachse des Elementes ausgerichteten und einen Keilwinkel von ca. 30° bis 60° aufweisenden Keilschneiden in der Weise vorgenommen wird, daß die Keile entweder zugleich, unter geringem Versatz der Keilschneiden gegeneinander, in das Element hineingedrückt werden oder daß die Keile nacheinander mit aufeinander ausgerichteten Keilschneiden in das Element unter jeweils entsprechender Abstützung des Elementes auf der Gegenseite hineingedrückt werden, und daß die beim Eindrücken der Keile in das Element ausweichenden Schenkel quer zur Bewegungsrichtung der Keile durch der Bohrungsrundung angepaßte Widerlager abgefangen werden.According to the invention, this object is achieved in that the division of the element into two legs by means of two wedges which can be moved in opposite directions with wedge edges aligned parallel to the longitudinal axis of the element and having a wedge angle of approximately 30 ° to 60 ° is carried out in such a way that either the wedges are pressed into the element at the same time, with a slight offset of the wedge-shaped cutting edges, or that the wedges are pressed into the element one after the other with wedge-shaped edges aligned with one another, with appropriate support of the element on the opposite side, and that when the wedges are pressed into the Element evasive legs are intercepted transversely to the direction of movement of the wedges through the bore rounded abutment.
Ein besonderer Vorteil dieses Verfahrens ist darin zu sehen, daß im wesentlichen ohne Rücksicht auf das Querschnittsprofil des Elementes stets nach außen abgerundete Schenkel erhalten werden, die abschnittsweise parallel zueinander verlaufen.A particular advantage of this method can be seen in the fact that, regardless of the cross-sectional profile of the element, legs which are rounded to the outside and which in sections run parallel to one another are always obtained.
Zwar ist aus der DE-PS 895 740 ein Verfahren und eine Vorrichtung zur Herstellung von Kreuzklammern für zahntechnische Zwecke bekannt, bei dem bzw. bei der schon ein Stück Flachdraht, das im Querschnitt einen rechteckförmigen Umriß hat, in zwei Äste gespalten wird, wobei ebenfalls zwei gegensinnig zueinander bewegbar vorgesehene Keile (dort als Meißel bezeichnet) mit parallel zur Längsachse des Drahtstückes ausgerichteten Keilschneiden verwendet werden.From DE-PS 895 740 a method and a device for producing cross brackets for dental purposes is known, in which or in which a piece of flat wire, which has a rectangular outline in cross section, is split into two branches, likewise two wedges (which are referred to as chisels), which can be moved in opposite directions to one another, are used with wedge cutting edges oriented parallel to the longitudinal axis of the wire piece.
Im Gegensatz zu dem erfindungsgemäßen Verfahren sind dort jedoch die quer zur Bewegungsrichtung der Keile bzw. Meissel vorgesehenen Widerlager federnd nachgiebig ausgebildet, so daß bei der Teilung des Flachdrahtstücks das Profil der Äste nicht verändert wird. Eine Profil- änderung der Äste wird vielmehr erst in einem gesonderten zweiten Preßvorgang vorgenommen.In contrast to the method according to the invention, however, the abutments provided transversely to the direction of movement of the wedges or chisels are designed to be resilient, so that the profile of the branches is not changed when the flat wire piece is divided. A profile change of the branches is made only in a separate second pressing process.
Ausführungsbeispiele der Erfindung werden nachstehend anhand von acht Figuren noch näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to eight figures.
Dabei zeigen
- Figur 1 und
Figur 2 die Herstellung des Klemmbereiches, wobei zwei gleichzeitig bewegbare Keile Verwendung finden, - Figur 3 und Figur 4 die Herstellung des Klemmbereiches unter Verwendung zweier nacheinander bewegbarer Keile,
- Figur 5, Figur 6 und Figur 7 eine Seitenansicht von zwei in ein Element eingearbeiteten Klemmbereichen, die um 90° gegeneinander verdreht sind, mit den zugehörigen Querschnittsbildern und
Figur 8 in Schrägsicht und stark vergrößert, die spezielle Form der auf das Element einwirkenden Keile und die sich hieraus ergebende Ausbildung der Schenkel des Elementes im Klemmbereich.
- FIG. 1 and FIG. 2 show the production of the clamping area, two wedges which can be moved simultaneously being used,
- 3 and FIG. 4 show the production of the clamping area using two wedges which can be moved in succession,
- 5, FIG. 6 and FIG. 7 show a side view of two clamping areas worked into an element, which are rotated by 90 ° with respect to one another, with the associated cross-sectional images and
- Figure 8 in an oblique view and greatly enlarged, the special shape of the wedges acting on the element and the resulting formation of the legs of the element in the clamping area.
Aus den Figuren 1 bis 4 ist zu ersehen, daß die Einarbeitung eines Klemmbereiches in ein stiftförmiges Element 1, das einen quadratischen Querschnitt aufweist (der Querschnitt des Elementes kann selbstverständlich auch rund, oval, rechteckig oder vieleckig sein) mit Hilfe zweier Keile 2, 3 vorgenommen wird, deren Keilschneiden 4 einen Winkel von 60° aufweisen. Die Keilschneiden 4 sind zueinander und zur Achse 5 des Elementes parallel gerichtet.It can be seen from FIGS. 1 to 4 that the incorporation of a clamping area into a pin-shaped element 1 which has a square cross section (the cross section of the element can of course also be round, oval, rectangular or polygonal) with the aid of two
Die Keile 2, 3 können entweder wie in den Figuren 1 und 2 dargestellt, gleichzeitig oder, wie aus den Figuren 3 und 4 zu ersehen, nacheinander in das Element 1 hineinbewegt werden. Wenn die Keile 2, 3 zugleich in das Element mit zueiander gegenläufiger Bewegungsrichtung ihrer Keilschneiden 4 hineinbewegt werden sollen, so ist es erforderlich, wie aus den Figuren 1 und 2 zu ersehen, die Bewegungsebenen 6 der Keile 2, 3 gegen eine durch die Achse 5 des Elementes 1 verlaufende Symmetrieebene 7 des Elementes 1 so zu versetzen, daß sich, wie insbesondere aus Fig. 2 zu ersehen ist, die beiden Keile 2, 3 in ihrer nach dem Aufteilen des Elementes 1 in zwei Schenkel 8 erreichten Endposition mit ihren Keilschneiden 4 gegenseitig überlappen.The
Durch das Aufteilen des Elementes 1 im Klemmbereich in zwei Schenkel 8 mit Hilfe der Keile 2, 3 wird u. a. erreicht, daß mit zunehmendem Eindringen der Keile 2, 3 in das Element 1 die Schenkel 8 zunehmend auseinander bewegt werden. Diese Bewegung wird jedoch durch zwei Widerlager 9 begrenzt, die an ihren dem Element 1 zugewandten Seiten als Halbschalen 10 ausgebildet sind, die der Rundung der Bohrung, in die das Element 1 eingesteckt werden soll, angepaßt sind. Dadurch werden die Schenkel 8 mit ihrer von der Achse 5 des Elementes 1 abgewandten Außenseite 11 durch die Keile 2, 3 gegen die Rundungen 10 der Widerlager 9 grepreßt und dadurch diesen Rundungen angepaßt. Das Element hat deshalb im Klemmbereich einen Querschnitt, vgl. hierzu die Figuren 6 und 7, bei dem jeder der beiden Schenkel 8 nach außen eine der Bohrungsrundung angepaßte Außenseite 11 und eine dem gegenüberliegenden Schenkel zugewandte keilförmige Innenseite 12 besitzt, so daß der die Schenkel 8 trennende Zwischenraum 13 schmetterlingsartig ausgebildet ist.By dividing the element 1 in the clamping area into two
Werden die Keile 2, 3 nacheinander in das Element 1 hineinbewegt, vgl. hierzu insbersondere die Fig. 3 und 4, so können die Keile 2,3 mit ihren Bewegungsebenen, diese stimmen mit den Symmetrieebenen der Keilschneiden 4 überein, auf eine durch'die Achse 5 des Elementes verlaufende Symmetrieebene 7 des Elementes 1 ausgerichtet werden.If the
Beim Hineindrücken eines der beiden Keile 2, 3 muß der jeweils andere Keil durch ein Abstützorgan 14 ersetzt werden, wobei das Abstützorgan 14 ein Ausweichen des Elementes 1 in Bewegungsrichtung eines der Keile 2, 3 verhindert.When one of the two
Die Ausformung der Außenseite 11 der Schenkel 8 wird auch bei einem nacheinander erfolgenden Eindrücken der Keile 2, 3 in das Element 1 in gleicher Weise wie bei dem Verfahren nach den Fig. 1 und 2 mit Hilfe zweier Widerlager 9 vorgenommen.The shaping of the outside 11 of the
Wie Figur 5 zeigt, können in ein Element 1 in Verlaufsrichtung des Elementes auch mehrere Klemmbereiche 15 eingearbeitet werden, wobei vorteilhaft die Klemmwirkung der aufeinanderfolgenden Klemmbereiche 15 um 90° gegeneinander verrsetzt wird.As FIG. 5 shows, a plurality of
Aus Fig. 8 ist zu ersehen, daß die Keile 2, 3 mit ihren Keilschneiden 4 zu den Verbindungspunkten 16 der Schenkel 8 hin jeweils abgeschrägt verlaufen, so daß sich die Schenkel 8 von einem mittleren Abschnitt 17 aus, in dem die Schenkel 8 parallel zueinander in einem bestimmten Abstand voneinander verlaufen und damit den eigentlichen Klemmbereich bilden, sich kontinuierlich wieder einander nähern, also aufeinander zu verlaufen. Dies ermöglicht es, den Querschnitt des Elementes 1 gegenüber einer Bohrung, in der der Klemmbereich 15 des Elementes 1 zur Wirkung kommen soll, relativ kleiner auszubilden, so daß das Element 1 die Bohrungswände nur im Bereich 17 berührt. In diesem Breich 1 hat das Element durch die der Rundung der Bohrung angepaßte Außenseite 11 der Schenkel 8 eine Kontur, die optimal auf die Bohrung abgestimmt ist. Der Querschnitt des restlichen Elementes 1 kann dagegen, z. B. einen Wrap-Stil zu erhalten, quadratisch oder rechteckig sein, jedenfalls dem jeweiligen Verwendungszweck entsprechend ausgebildet sein.From Fig. 8 it can be seen that the
