Description

Die Erfindung betrifft ein Verfahren zum Verstärken eines Wandbereichs von einem dreidimensionalen Beschlag für hohe Drehmomentbelastungen, bei dem aus einem Bandstreifen eine Platine mit im wesentlichen gleichmäßig gekrümmter Außenkontur ausgeschnitten und anschließend die Platine zu einem topfförmigen Körperteilmittels eines aus Stempel, Gegenstempel, Matrize, Ringzacke und Führungsplatte bestehenden Umform- und Feinschneidwerkzeugs umgeformt und feingeschnitten wird, wobei ein umlaufender Rand für eine Verzahnung an dem Körperteil ausgeformt wird und wobei die Wanddicke des Wandbereichs zwischen dem Rand und dem topfförmigen Körperteil des Beschlags durch eine gezielte Material verschiebung mit einem mindestens zweistüfigen kohfließ pressvorgang jeweils in entgegengesetzte Fließrichtungen schräg der Stempelbewegung so verstarkt wird, dass die gezielte Material verschiebung den durch die Umformung hervorgerüfenen Material abfluß im Wandbereich annähernd wieder ausgleicht.The invention relates to a method for reinforcing a wall portion of a three-dimensional fitting for high torque loads, in which cut out of a tape strip a board having a substantially uniformly curved outer contour and then the board to a cup-shaped body part means of a punch, counter punch, die, ring prong and guide plate existing forming and fine cutting tool is reshaped and fine-cut, wherein a peripheral edge is formed for a toothing on the body part and wherein the wall thickness of the wall portion between the edge and the cup-shaped body part of the fitting by a targeted material displacement with an at least two-stage kohfließ press process respectively in opposite directions of flow obliquely the punch movement is so strengthened that the targeted material displacement caused by the deformation material drain in the Almost compensates wall area again.

Stand der TechnikState of the art

Sitzverstellungskomponenten, beispielsweise feste und schwenkbewegliche Gelenkteile von Gelenkbeschlägen, werden bekanntlich durch Umformen und Feinstanzen oder -schneiden in einer für den endgültigen Einsatzzweck sehr hohen Maßhaltigkeit hergestellt (siehe EP 0 694 434 B1 , DE 32 44 399 C2 , DE 28 34 492 C2 , DE 32 27 222 C1 ).Seat adjustment components, such as fixed and pivotable hinge parts of hinge fittings are known to be produced by reshaping and fine blanking or cutting in a very high dimensional accuracy for the final use (see EP 0 694 434 B1 . DE 32 44 399 C2 . DE 28 34 492 C2 . DE 32 27 222 C1 ).

Diese bekannten Gelenkteile bestehen im wesentlichen aus einem topfförmig geformten Körperteil mit Ausdrückungen und/oder Abprägungen und/oder Einsenkungen und/oder Aussparungen und/oder Durchsetzungen und/oder Bohrungen und/oder Zapfenpressen. Der mit einer gleichmäßig gekrümmten Außenkontur versehene Körperteil hat einen umlaufenden Rand, in dem eine radial nach innen in das Körperteil gerichtete Verzahnung eingearbeitet ist. Diese Verzahnung muss funktionsmäßig sehr hohe Drehmomente übertragen, so dass der Wandbereich zwischen Rand und dem Körperteil, d.h. die Anbindung zum topfförmigen Körperteil erheblichen Belastungen ausgesetzt ist, was oft zum Bruch führt. Dies beeinträchtigt die Sicherheit und Zuverlässigkeit der Sitzverstellungskomponenten.These known joint parts consist essentially of a cup-shaped body part with expressions and / or stampings and / or depressions and / or recesses and / or enforcements and / or bores and / or journal presses. The body part provided with a uniformly curved outer contour has a peripheral edge in which a toothing directed radially inwards into the body part is incorporated. This gearing must functionally transmit very high torques, so that the wall area between the edge and the body part, i. the connection to the pot-shaped body part is exposed to considerable loads, which often leads to breakage. This affects the safety and reliability of the seat adjustment components.

Des Weiteren ist aus der US 5 531 504A ein Kaltfließpressvorgang bekannt, mit dem eine Verzahnung an einem Körperteil eines Gelenkbeschlages ausgeformt und durch eine gezielte Materialverschiebung der von der Umformung hervorgerufene Materialabfluß im Wandbereich des Körperteils annähernd wieder ausgeglichen wird.Furthermore, from the US 5 531 504A a cold extrusion process is known, with which a toothing on a body part of a hinge fitting formed and approximately offset by a targeted material displacement caused by the deformation material drainage in the wall portion of the body part.

Aufgabenstellungtask

Bei diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art derart zu verbessern, dass Gelenkbeschläge mit einer weitaus höheren Sicherheit gegen Bruch des Wandbereiches zwischen dem eine Innenverzahnung tragenden Rand und dem topfförmigen Körperteil des Gelenkbeschlags kostengünstig zur Verfügung gestellt werden können.In this prior art, the present invention seeks to improve a method of the type mentioned in such a way that hinge fittings are provided at a much higher security against breakage of the wall area between the inner toothing bearing edge and the cup-shaped body part of the hinge fitting cost can.

Diese Aufgabe wird durch ein Verfahren der eingangs genannten Gattung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This object is achieved by a method of the type mentioned with the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen des Verfahrens sind den Unteransprüchen entnehmbar.Advantageous embodiments of the method are the dependent claims.

Der nach dem erfindungsgemäßen Verfahren hergestellte Gelenkbeschlag zeichnet sich dadurch aus, dass die Wanddicke des Wandbereichs zwischen dem Rand und dem topfförmigen Körperteil des Beschlags durch eine gezielte Materialverschiebung mit mindestens einem zweistufigen Kaltfließpressvorgang jeweils in entgegengesetzte Fließrichtungen schräg zur Stempelbewegung trotz Umformung eine etwa der ursprünglichen Wanddicke entsprechenden Dicke erreicht und mühelos extrem hohen Bruchlasten widersteht.The hinge fitting produced by the method according to the invention is characterized in that the wall thickness of the wall portion between the edge and the cup-shaped body part of the fitting by a targeted material displacement with at least a two-stage Kaltfließpressvorgang each in opposite directions of flow obliquely to the punch movement despite reshaping an approximately the original wall thickness Thickness and effortlessly withstands extremely high breaking loads.

Dies ist mit dem außerordentlichen Vorteil verbunden, dass problemlos große Drehmomente übertragen werden können, so dass Gelenkbeschläge zur Verfügung stehen, die auch für spezielle oder bestimmte Belastungswerte, beispielsweise für die Befestigung eines Sicherheitsgurtes an der Sitzlehne eines Pkw, geeignet sind.This is associated with the extraordinary advantage that large torques can be transmitted without difficulty, so that joint fittings are available, which are also suitable for specific or specific load values, for example for fastening a seat belt to the seat back of a car.

Durch die Materialverschiebung in den Wandbereich der Anbindung entsteht zusätzlich der Vorteil, dass das Anschneiden über die gesamte Materialdicke möglich wird, so dass der Einsatzbereich des Feinschneidens auch an komplexen und kompliziert aufgebauten dreidimensionalen multifunktionalen Teilen wirtschaftlich möglich wird.Due to the material displacement in the wall region of the connection, the additional advantage arises that the cutting across the entire material thickness is possible, so that the application of fineblanking is economically possible even on complex and complicated constructed three-dimensional multifunctional parts.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung unter Bezugnahme auf die beigefügten Zeichnungen.Further advantages and details will become apparent from the following description with reference to the accompanying drawings.

Fig. 4 einer perspektivischen Darstellung eines Schnitts durch einen dreidimensionalen Gelenkbeschlag, der nach dem erfindungsgemäßen Verfahren hergestellt wurde. Fig. 4 a perspective view of a section through a three-dimensional hinge fitting, which was prepared by the method according to the invention.

Mit dem erfindungsgemäßen Verfahren sollen dreidimensionale multifunktionale Gelenkbeschläge 1 für Autositzkomponenten hergestellt werden, die auch bei hohen Belastungen, beispielsweise über 6000 N, bruchsicher sind.The method according to the invention is intended to produce three-dimensional multifunctional articulated fittings 1 for car seat components which are shatter-proof even at high loads, for example above 6000 N.

Die Fig. 1 zeigt einen Schnitt durch einen kreisrunden, jedoch auf solche geometrische Formen nicht festgelegten Gelenkbeschlag 1, der aus einer Platine 2 (siehe Fig. 3) eines Bandstreifen aus Stahl mit einer Dicke von beispielsweise 3 bis 8 mm hergestellt wurde.The Fig. 1 shows a section through a circular, but not fixed to such geometric shapes hinge fitting 1, which consists of a board 2 (see Fig. 3 ) of a steel strip strip having a thickness of, for example, 3 to 8 mm.

Die Platine 2 wird einem kombinierten Umform- und Feinschneidprozess unterworfen, in dessen Verlauf der dreidimensionale Gelenkbeschlag 1 entsteht.The board 2 is subjected to a combined forming and fine blanking process, in the course of the three-dimensional hinge fitting 1 is formed.

Der Gelenkbeschlag 1 besteht aus einem topfförmigen Körperteil 3, in dem durch Umformvorgänge Ausdrückungen 4, Vertiefungen 5, eine Abprägung 6 und eine Bohrung 7 eingeformt bzw. eingebracht wurden. Der Körperteil 3 weist einen umlaufenden Rand 8 auf, welcher eine radial nach innen ausgerichtete Verzahnung 9 besitzt. Abprägung 6 und Rand 8 sind durch einen Wandbereich 10 verbunden.The hinge fitting 1 consists of a cup-shaped body part 3, in which by forming operations expressions 4, recesses 5, a stamping 6 and a bore 7 were formed or introduced. The body part 3 has a peripheral edge 8 , which has a radially inwardly aligned toothing 9 . Embossment 6 and edge 8 are connected by a wall region 10 .

Der Wandbereich 10 zwischen dem Rand 8 und der Abprägung 6 des topfförmigen Körperteils 3 wird beim Umformen geschwächt, d.h. es findet ein Abfließen des Materials aus dem Wandbereich 10 in Richtung der Abprägung 6 statt. Dies führt bei Belastung zu dem in Fig. 2 gezeigten Riss R im Wandbereich 10. The wall portion 10 between the edge 8 and the embossment 6 of the cup-shaped body part 3 is weakened during forming, ie there is a flow of material from the wall portion 10 in the direction of the impression 6 instead. This leads to the load under load Fig. 2 shown crack R in the wall area 10.

In den Fig. 3a bis 3d ist der Ablauf des erfindungsgemäßen Verfahrens schematisch dargestellt. Gemäß Fig. 3a ist die Platine 2 zwischen einer Führungsplatte 11 und einer Matrize 12 fest verspannt. Der von der Führungsplatte 11 geführte Stempel 13 führt eine Bewegung in Richtung SM der Matrize 12 aufwärts aus. In der Matrize 12 ist ein Raum 14 vorgesehen, der etwas seitlich von der Stempelachse A liegt.In the Fig. 3a to 3d the sequence of the method according to the invention is shown schematically. According to Fig. 3a the board 2 between a guide plate 11 and a die 12 is firmly clamped. The guided by the guide plate 11 punch 13 performs a movement in the direction SM of the die 12 upwards. In the die 12 a space 14 is provided which lies somewhat laterally of the punch axis A.

Im ersten Schritt des erfindungsgemäßen Verfahrens bewegt sich der Stempel 13 in Richtung Matrize 12 aufwärts, wodurch ein entsprechendes Materialvolumen V in dem Raum 14 seitlich vom Stempel 13 abfließt (siehe Pfeilrichtung C). Dieses Materialvolumen V füllt den Raum 14 und es entsteht dadurch ein Materialaufbau 15 an der zum Stempel 13 gelegenen Gegenseite G der Platine 2. In the first step of the method according to the invention, the punch 13 moves upwards in the direction of the die 12 , whereby a corresponding volume of material V in the space 14 flows off laterally from the punch 13 (see arrow direction C). This volume of material V fills the space 14 and thereby creates a material structure 15 at the opposite side of the punch 13 G of the board . 2

Die so umgeformte Platine 2 wird im zweiten Schritt des erfindungsgemäßen Verfahrens zusätzlich durch eine Ringzacke 16 festgehalten und der Materialaufbau 15 an der Gegenseite G durch einen Gegenstempel 17 in eine zur Pfeilrichtung C entgegengesetzte Richtung (siehe Pfeilrichtung D) verschoben, so dass Material in einen seitlich vom Stempel 13 befindlichen Raum 18 abfließt und den Wandbereich 10 zwischen Rand 8 und Abprägung 5 im topfförmigen Körperteil 3 auf die Wanddicke s verstärkt (siehe Fig. 3c und 3d), die in diesem Beispiel etwa dem beim Umformen abgeflossenen Materialvolumen entspricht.The thus formed board 2 is additionally held in the second step of the method according to the invention by a ring prong 16 and the material structure 15 on the opposite side G by a counter punch 17 in a direction opposite to the arrow C direction (see arrow D) , so that material in a laterally from the stamp 13 located space 18 flows away and the wall portion 10 between the edge 8 and stamping 5 in the cup-shaped body part 3 to the wall thickness s amplified (see Fig. 3c and 3d ), which in this example corresponds approximately to the volume of material drained off during the forming process.

Durch die Bemessung der Räume 14 und 18 kann das zu verschiebende Materialvolumen V bestimmt werden, wodurch es möglich ist, die Wanddicke s des Wandbereichs 10 auf ein für eine bestimmte Bruchlast sicheres Maß zu verstärken. Ein solches bruchsicheres Gelenkteil 1 zeigt Fig. 4. Die zu wählende Bemessung der Räume 14 und 18 ergibt sich aus dem Fließverhalten des Materials der Platine 2, der Härte und Belastbarkeit der Stempel 13 und 17, den Schmierstoff, dem Aufbau des Werkzeugs sowie der für den Anwendungsfall notwendigen Bruchlast.By dimensioning the spaces 14 and 18 , the material volume to be displaced V can be determined, whereby it is possible to increase the wall thickness s of the wall portion 10 to a certain degree for a certain breaking load measure. Such a shatter-proof joint part 1 shows Fig. 4 , The dimensioning of the spaces 14 and 18 to be selected results from the flow behavior of the material of the board 2, the hardness and load capacity of the punches 13 and 17, the lubricant, the structure of the tool and the breaking load necessary for the application.

Damit wird es möglich, mühelos Bruchsicherheiten zu erreichen, die die Bruchlast in diesem Wandbereich beträchtlich übersteigt.
