Ein Schloss eines Kraftfahrzeugs weist in der Regel ein Gesperre umfassend eine Drehfalle und wenigstens eine Sperrklinke auf, mit der eine Drehu ng der Drehfalle in Öffnungsrichtung blockiert werden ka nn . A lock holder usually consists of a base plate and a lock bracket, and also a locking pin or lock holder bracket. The base plate typically has recesses, for example in the form of drill holes, in order to permit fastening of the lock holder to a body of a motor vehicle, for example.

Aufgru nd des Eingriffes zwischen Schlosshalter und Drehfalle beim Schlie ßvorgang, aber auch beim Öffnen des Schlosses, ist ein Sc hlosshalter regelmäßig hohen Belastungen ausgesetzt. I nsbesond ere im Crashfall, wo besonders starke Verformungen auftreten. Für eine Herstellung eines einteiligen Schlosshalters ist es bekannt, ein Ausgangsmaterial - also einen Rohling - durch Kaltfließpressen oder Kaltstauchen massiv umzuformen. Die Druckschrift DE 102007041 479 AI offenbart einen einstückigen Schlosshalter für ein Kraftfahrzeug¬ schließsystem, der als Massivbauteil mit verschiedenen Querschnittsstärken ausgeführt ist, um eine günstige Fertigung sowie verbesserte mechanische Eigenschaften zu erzielen. Die Druckschrift DE 10 2010 024 510 AI offenbart ein Verfahren zur Herstellung eines Schlosshalters, bei dem ein Rohmaterial zunächst abgeschert wird und dann zum Warmschmieden auf Bearbeitungstemperaturen oberhalb der Rekristallisationstemperatur gebracht und durch Druckumformen mittels Schmiedehämmern zu einem Schlosshalter geformt wird. On the basis of the engagement between the lock holder and the rotary latch during the closing process, but also when the lock is opened, a lock holder is regularly exposed to high loads. Especially in the event of a crash, where particularly strong deformations occur. For a production of a one-piece lock holder, it is known to massively transform a starting material - ie a blank - by cold extrusion or cold heading. The publication DE 102007041 479 AI discloses a one-piece lock holder for a motor vehicle ¬ locking system, which is designed as a solid component with different cross-sectional thicknesses in order to achieve a favorable production and improved mechanical properties. Document DE 10 2010 024 510 A1 discloses a method for producing a lock holder, in which a raw material is first sheared off and then brought to working temperatures above the recrystallization temperature for hot forging and formed by pressure forming by means of forging hammers to form a lock holder.
Die Druckschrift DE 10 2010 011 716 AI offenbart ein Verfahren zur Herstellung eines Schlosshalters, bei dem durch Kaltfließpressen aus einem Rohmaterial ein T-förmiges Halbzeug geformt wird.

Anschließend wird das T-förmige Halbzeug beispielsweise durch Kaltstanzen weiterverarbeitet, um Haltebohrungen in der Grundplatte und eine Ausnehmung im Schlossbügel vorzusehen. Das Verfahren ist dafür konzipiert, eine aufwendige Nachbearbeitung des Schlosshalters einzusparen.

The lock holder can be formed from a round stock by massive forming into a T-shaped stock. Subsequently, the T-shaped semifinished product is further processed, for example by cold punching to provide retaining holes in the base plate and a recess in the lock bracket. The method is designed to save a costly reworking of the lock holder.

Der S-Schlag dient in erster Linie dazu, eine Verformung und ein Verhaken mit der Schlossplafte im Crashfall zu vermeiden, so dass ein Krafffahrzeugschloss weifer zuverlässig geöffnet werden kann. From the not yet published document DE 102010054369 a method for the manufacture of lock holders is known in which by cold extrusion a T-shaped semi-finished product is formed and then holding holes and recesses are formed by punching. In addition, for the formation of an S-blow during forming to a T-shaped semi-finished a bead of material arranged on the leg parallel to the base plate of the lock strap. The S-beat serves primarily to avoid deformation and snagging with the lock plates in the event of a crash, so that a Krafffahrzeugschloss can be opened wilder reliable.
Der Umformvorgang durch plastische Änderung eines vorgegebenen festen Ausgangsrohlings ist grundsätzlich mit dem Problem verbunden, dass hohe Umformkräfte erforderlich sind, die zugleich eine hohe Werkzeugbeanspruchung zur Folge haben. Ferner sind für die Bereifstellung der hohen Umformkräfte entsprechend dimensionierte Maschinen wie Pressen erforderlich. The forming process by plastic change of a given fixed starting blank is basically associated with the problem that high forming forces are required, which at the same time have a high tool stress result. Furthermore, appropriately dimensioned machines such as presses are required for equipping the high forming forces.
Soweit nachfolgend nicht anders angegeben, können die vorgenannten Merkmale einzeln oder in beliebiger Kombination mit dem Gegenstand der nachfolgend beschriebenen Erfindung beliebig kombiniert werden. Unless otherwise stated below, the abovementioned features may be combined as desired individually or in any combination with the subject matter of the invention described below.
Es ist Aufgabe der Erfindung, die Herstellung eines Schlosshalters weifer zu entwickeln. It is an object of the invention to develop the production of a lock holder weifer.
Die Aufgabe der Erfindung wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgesfaltungen ergeben sich aus den Unteransprüchen. Nach dem beanspruchten Verfahren wird ein Schlosshalfer aus einem metallischen Ausgangsrohling durch Kaltumformung insbesondere Kaltstauchen umgeformt. Der Ausgangsrohling ist vor dem Umformvorgang im Wesentlichen block- oder zylinderförmig ausgebildet und wird derart umgeformt, dass eine Kaltverfestigung des Schlosshalters erfolgt. Bevorzugt erfolgt beim U mformvorgang eine endformnahe Form änderung des Ausgangsrohlings. Der umgeformte Ausgangsrohling ents pricht nach dem U mformvorgang dann im Wesentlichen der Endform des Schlosshalters. Aussparungen z.B. in Form von Bohrungen an der Gru nd platte sowie die Ausnehmung im Schlossbügel können gru ndsätzlich je nach Anforderung bereits im U mformvorgang oder in einer Nach bearbeitung beispielsweise durch Stanzen oder Schneiden ausgebildet werden. Wesentlich ist die Ü berlegung, die U mformung des Ausgangsrohlings zu einem einteiligen Schlosshalter mit einem im Wesentlichen block- oder zyli n derförmigen Ausgangsrohling vorzunehmen, um in gezielter Weise einen beanspruchungsgerechten Schlosshalter auszubilden, der zudem auc h fertigungstechnisch vorteilhaft herstell bar ist. Mit dem vorschlagsgemäßen Verfahren gelingt eine gezielte Einstellung der mechanischen Eigenschaften des Schlosshalters, die zu ganz bestimmten Anwendu ngseigenschaften eines so hergestellten Schlosshalters führen . Die Kaltumformung bewirkt ferner eine Erhöhung der Festigkeit, auch Kaltverfestigung genannt. Dadurch können Materialien für den Ausgangsrohling verwendet werden, die im ursprünglichen Zustand eine niedrige Festigkeit aufweisen und als umgeformter Schlosshalter aufgru nd der Kaltverfestigung höher beansprucht werden kön nen, oh ne dass hochwertige Werkstoffe als Ausgangsrohling eingesetzt werden müssen. The object of the invention is achieved by a method having the features of claim 1. Advantageous Ausfolds emerge from the dependent claims. According to the claimed method, a lock halter is formed from a metallic starting blank by cold forming, in particular cold heading. The starting blank is formed essentially block-shaped or cylindrical before the forming process and is reshaped such that a cold hardening of the lock holder takes place. Preferably takes place during U-forming a near-net shape change of the starting blank. The reshaped starting blank then essentially follows the final shape of the lock holder after the forming process. Recesses, for example in the form of holes on the base plate as well as the recess in the lock bracket can be made in accordance with the requirements already in the forming process or in a post-processing, for example by punching or cutting. It is essential to make the U-shaping of the starting blank to a one-piece lock holder with a substantially block- or zyli n derförmigen starting blank to train in a targeted manner a claim-appropriate lock holder, which is also auc h manufacturing technology advantageous producible bar. With the proposed method succeeds a targeted adjustment of the mechanical properties of the lock holder, which lead to very specific appli ngseigenschaften of a lock holder thus produced. The cold forming also causes an increase in strength, also called strain hardening. This makes it possible to use materials for the starting blank, which have a low strength in the original state and, as a formed lock holder, can be subjected to higher levels of work hardening, without the need to use high-grade materials as the starting blank.
Darü ber hinaus lassen sich durch die ganz bestimmte Formgebung des Ausga ngsrohlings die für die Kaltumformung erforderlichen U mformkräfte gezielt reduzieren, so dass die hohen Werkzeug beanspruchungen vorteilhaft minimiert werden . Die für die Herstellung benötigten Maschinen wie Pressen lassen sich in geeigneter Weise kleiner dim ensionieren, so dass eine insgesamt optimierte Fertigung ermöglicht wird . Die U mformung des Rohlings erfolgt vorzugsweise durch Kaltstauchen oder Kaltfließpressen. Der Ausgangsrohling wird bei derartigen U mformverfahren weitgehend ausgenutzt, so dass große Stoffeinsparungen insbesondere gegenüber spanendenIn addition, can be specifically reduced by the very specific shape of Ausga ngsrohlings required for the cold forming U forming forces, so that the high tool stresses are advantageously minimized. The machines required for the production, such as presses, can be suitably dimensioned to be smaller, so that an overall optimized production is made possible. The U-shaping of the blank is preferably carried out by cold heading or cold extrusion. The starting blank is largely exploited in such U molding process, so that large material savings in particular against cutting
Bearbeitu ngsverfahren möglich sind. Der Ausgangsrohling ist daher vorzu gsweise volumengleich zu dem umgeformten Schlosshalter. Darüber hina us ermöglichen Kaltumformverfahren wie Kaltstauchen oder Kaltfließpressen besonders kurze Fertigungszyklen selbst bei komplexen Formteilen, da das gesamte Rohlingvolumen gleichzeitig oder in mehreren U mformstufen endformnah u mgeformt wird. Processing procedures are possible. The starting blank is therefore preferably equal in volume to the formed lock holder. In addition, cold forming processes such as cold heading or cold extrusion allow particularly short production cycles, even for complex molded parts, since the entire blank volume is formed at the same time or in several forming steps to near net shape.
Bei ei ner Ausführungsform der Erfindung wird als Ausga ngsrohling ein Dra ht bzw. ein Profildraht verwendet, vorzugsweise mit einer Querschnittsfläche von 450 mm2 bis 1 1 25 mm2. Zur Verarbeitung als Ausga ngsrohling im vorschlagsgemäßen Verfahren lassen sich Drähte bzw. Profildrähte in einfacher Weise durch Abscheren oder Sägen geeig net verarbeiten . Die gezielte Auswahl der Querschnittsfläche für einen Draht bzw. Profildraht trägt dazu bei, dass durch die Kaltu mformu ng wie Kaltstauchen oder Kaltfließpressen Schlosshalter mit optimierten Festigkeits- und Dauerfestigkeitswerten hergestellt werden . In egg ner embodiment of the invention is as Ausga ngsrohling a Dra ht or a profile wire used, preferably with a cross-sectional area of 450 mm 2 to 1 1 25 mm. 2 For processing as Ausga ngsrohling in the proposed method, wires or profile wires can be processed in a simple manner by shearing or sawing appro net. The selective selection of the cross-sectional area for a wire or profile wire contributes to the fact that the Kaltu mformu ng such as cold heading or cold extrusion press lock holders with optimized strength and fatigue strength values are produced.
Bei ei ner Ausführungsform weist der Ausgangsrohling eine Breite von 1 5 mm bis 25 m m und/oder eine Länge von 30 m m bis 45 m m auf . I m Falle eines im Wesentlichen zylinderförmigen Ausgangsrohling ist der Durch messer bevorzugt 1 5 m m bis 35 mm. I n weiterer Ausgestaltung ist die Höhe des Ausgangsrohlings wenigstens 25 mm, weiter bevorzugt 25 mm bis 45 m m. Es hat sich gezeigt, dass sich derartig dimensionierte Ausga ngsrohlinge besonders vorteilhaft für das vorschlagsgemäße Verfahren eignen und besonders gute Ergebnisse im Hin blick auf die mechanischen Eigenschaften sowie auf die Anwendun gseigenschaften eines Schlosshalters erzielen, wie Versuche gezeigt haben . Um eine günstige Verfestigungswirkung im Schlosshalter zu erzielen, erfolgt bei einer Ausführungsform die Hauptformänderung beim Umformvorgang im Wesentlichen senkrecht zur Querschnittsfläche bzw. zur Profilfläche des Ausgangsrohlings. Die Querschnittsfläche bzw. Profilfläche wird grundsätzlich durch die Breite und die Länge definiert, bei im Wesentlichen zylinderförmigen Ausgangsrohlingen durch den Durc hmesser. Die Hau ptformänderung beeinflusst maßgeblich die Verfestigungswirkung beim Umformen, so dass auf diese Weise die Kaltverfestigung des Schlosshalters geeignet optimiert wird . In egg ner embodiment, the starting blank has a width of 1 5 mm to 25 mm and / or a length of 30 mm to 45 mm. In the case of a substantially cylindrical starting blank, the diameter is preferably 1 5 mm to 35 mm. In a further embodiment, the height of the starting blank is at least 25 mm, more preferably 25 mm to 45 m m. It has been found that such dimensioned Ausga ngs blanks are particularly advantageous for the proposed method and achieve particularly good results in Hin view of the mechanical properties and on the appli gseigenschaften a lock holder, as experiments have shown. In order to achieve a favorable solidification effect in the lock holder, in one embodiment, the main shape change during the forming process is substantially perpendicular to the cross-sectional area or to the profile surface of the starting blank. The cross-sectional area or profile surface is basically defined by the width and the length, in the case of substantially cylindrical starting blanks through the diameter of the diameter. The Ht ptformänderung significantly affects the solidification effect during forming, so that the cold work hardening of the lock holder is optimized in this way.
Der Durchmesser der Grund platte ist je nach Ausgestaltung des Ausga ngsrohlings bevorzugt zwischen 40 mm und bis 80 mm, vorzugsweise 50 mm. Vorzugsweise sind an der Grundplatte wenigstens zwei Aussparu ngen in Form von Bohrungen vorgesehen, die eine Befestigu ng des Schlosshalters ermöglichen. Die Aussparungen sind vorzugsweise ra ndseitig an der Grundplatte vorgesehen, um eine sta bile Befestigung beispielsweise an eine Karosserie eines Fahrzeugs zu ermöglichen . The diameter of the base plate is depending on the configuration of the Ausga ngsrohlings preferably between 40 mm and 80 mm, preferably 50 mm. Preferably, at least two Aussparu are provided in the form of holes on the base plate, which allow a Befestigu ng of the lock holder. The recesses are preferably provided ra ndseitig on the base plate to allow a sta bile attachment, for example, to a body of a vehicle.
Auss parungen in der Grund platte und/oder eine Ausnehmung im Schl oss bügel können bereits beim Umformvorgang durch spezielle Werkzeugeinsätze gebildet werden . Alternativ ist es möglich, die Auss paru ngen sowie die Ausnehmung in einem separaten Verfahrensschritt beispielsweise durch Ausstanzen oder Ausschneiden vorzusehen. Cut-outs in the base plate and / or a recess in the lock bracket can already be formed during the forming process by special tool inserts. Alternatively, it is possible to provide the outer edges and the recess in a separate process step, for example by punching or cutting.
Es hat sich in Versuchen gezeigt, dass sich das vorschlagsgemäße Verfahren besonders gut mit Vergütungsstählen als Werkstoff für die Ausgangsrohlinge anwenden lässt. Vorteilhafte Stahlsorten sind: 38Cr2, 46Cr2, 34Cr4 34CrS4, 37Cr4, 37CrS4, 41 Cr4( 41 CrS4, 25CrMo4, 25CrMoS4, 34CrMo4, 34CrMoS4, 42CrMo4, 42CrMoS4, 50CrMo4, 34CrNiMo6, 30CrNiMo8, 35NiCr6, 36NiCrMol6, 39NiCrMo3, 30NiCrMol 6-6, 51CrV4. It has been shown in experiments that the proposed method can be used particularly well with tempered steels as the material for the starting blanks. Advantageous steel grades are: 38Cr2, 46Cr2, 34Cr4 34CrS4, 37Cr4, 37CrS4, 41Cr4 ( 41CrS4, 25CrMo4, 25CrMoS4, 34CrMo4, 34CrMoS4, 42CrMo4, 42CrMoS4, 50CrMo4, 34CrNiMo6, 30CrNiMo8, 35NiCr6, 36NiCrMol6, 39NiCrMo3, 30NiCrMol 6-6, 51CrV4.
Um insbesondere die Streckgrenze und Festigkeit zu erhöhen, sind besonders vorteilhaft mangan- und/oder borlegierte Stähle wie 20MnB5, 30MnB5, 38MnB5, 27MnCrB5-2, 33MnCrB5-2 und 39MnCrB6-2 anwendbar. In particular, to increase yield strength and toughness, manganese and / or boron alloy steels such as 20MnB5, 30MnB5, 38MnB5, 27MnCrB5-2, 33MnCrB5-2 and 39MnCrB6-2 are particularly applicable.
Ganz generell hat sich die Anwendung von kaltgestauchten- bzw. kaltgepressten Stählen als vorteilhaft erwiesen, insbesondere in Form von Drähten. Vorteilhafte Stahlsorten sind: Cq 22 (Werkstoffnummer: 1.1152), C35EC, C35RC, C45EC, C45RX, 37Mo2, 38Cr2, 46Cr2, 34Cr4, 37Cr4, 41Cr4, 41CrS4, 25CrMo4, 25CrMoS4, 34CrMo4, 37CrMo4, 42CrMo4, 42CrMoS4, 34CrNiMo6, 41 NiCrMo7-3-2. Um insbesondere einen Schlosshalter mit höherer Festigkeit zu realisieren, werden borlegierte Stähle verwendet. Besonders vorteilhaft anwendbar sind: 17B2, 23B2, 28B2, 33B2, 38B2, 17MnB4, 20MnB4, 23MnB4, 27MnB4, 30MnB4, 36MnB4, 37MnB5, 30MoBl, 32CrB4, 36CrB4, 31CrMoB2-l. Schlossbügel und Grundplatte werden beim Umformvorgang insbesondere einteilig hergestellt. Um den aus der Grundplatte vorstehenden Schlossbügel beanspruchungsgerecht auszuführen, ist in einer bevorzugten Ausgestaltung vorgesehen, zwischen Grundplatte und Schlossbügel einen verstärkten Übergangsbereich vorzusehen. Die Verstärkung des Übergangsbereiches erhöht die Belastbarkeit des Schlossbügels, so dass der Schlosshalter verbessert Kräfte aufzunehmen vermag. In general, the use of cold upset or cold pressed steels has proven to be advantageous, especially in the form of wires. Advantageous steel grades are: Cq 22 (material number: 1.1152), C35EC, C35RC, C45EC, C45RX, 37Mo2, 38Cr2, 46Cr2, 34Cr4, 37Cr4, 41Cr4, 41CrS4, 25CrMo4, 25CrMoS4, 34CrMo4, 37CrMo4, 42CrMo4, 42CrMoS4, 34CrNiMo6, 41 NiCrMo7 -3-2. In particular, to realize a lock holder with higher strength, boron-alloyed steels are used. Particularly advantageously applicable are: 17B2, 23B2, 28B2, 33B2, 38B2, 17MnB4, 20MnB4, 23MnB4, 27MnB4, 30MnB4, 36MnB4, 37MnB5, 30MoBl, 32CrB4, 36CrB4, 31CrMoB2-l. Locking bracket and base plate are made in one piece during the forming process. In order to stressfully execute the lock bracket protruding from the base plate, it is provided in a preferred embodiment to provide a reinforced transitional area between the base plate and the lock bracket. The reinforcement of the transition area increases the load capacity of the lock bracket, so that the lock holder can absorb improved forces.
Bevorzugt wird der Umformvorgang des Ausgangsrohlings in mehreren Schritten bzw. Stufen durchgeführt. Je nach Anforderung kann der Umformvorgang zwei oder mehr Schritte bzw. Stufen umfassen. Im Falle eines Kaltstauchens wird bevorzugt ein Verjüngen, gegebenenfalls ein Vorsta u chen und schließlich ein Fertigstauchen durchgeführt, um keine unzulässigen Formänderungen insbesondere Werkstofftrennungen an einzel nen Stellen hervorzurufen und ein Fließen beim Umformen des Werkstoffs zu ermöglichen. Preferably, the forming process of the starting blank is carried out in several steps or stages. Depending on the requirement, the forming process may comprise two or more steps. In the case of cold upsetting, it is preferable to taper, if necessary Vorsta u chen and finally a finish dipping carried out in order not to cause impermissible changes in shape, in particular material separations at individual NEN points and to allow flow during the forming of the material.
Um die Eigenschaften wie Festigkeit, H ärte und Dehnung zu beeinflussen und Eigenspan nungen im umgeformten Schlosshalter zu vermindern, wird bei einer Ausführungsform der Schlosshalter nach der U mformung einer Wärmebeh andlung insbesondere einer Vergütung unterzogen. Hierbei wird der Schlosshalter bevorzugt einer definierten Temperatur-Zeit-Folge unterworfe n, die gegebenenfalls mit zusätzlichen chemischen oder mec hanischen Einwirkungen gekoppelt wird. Durch eine geeignete Wärmebeh andlung lässt sich ferner die Zugfestigkeit des Schlosshalters je nach Anforderungen und verwen deten Werkstoff erhöhen. Mit der Durchführu ng von Wärmebehandlungen a n umgeformten Schlosshaltern sind insbesondere Zugfestigkeiten von größer als 30 kN möglich. In order to influence the properties such as strength, hardness and elongation and to reduce intrinsic stresses in the formed lock holder, in one embodiment the lock holder is subjected to a heat treatment, in particular, a compensation after the shaping. In this case, the lock holder is preferably subjected to a defined temperature-time sequence, which is optionally coupled with additional chemical or mechanical effects. By a suitable heat treatment, furthermore, the tensile strength of the lock holder can be increased depending on the requirements and the material used. In particular, tensile strengths of greater than 30 kN are possible with the performance of heat treatments on formed lock holders.
Um die Eigenschaften der Oberfläche wie Ma ßgena uigkeit weiter zu verbessern, wird in einer weiteren Ausgestaltung des Verfahrens nach dem U mformvorgang des Schlosshalters eine Oberflächen behandlu ng insbesondere ein Flachprägen, Glattprägen oder Ma ßprägen durchgeführt. Es ist a uch möglich, bestimmte Bereiche des Schlosshalters gezielt durch Oberflächen behandlung nachzubearbeiten. So kann beispielsweise am Bereich, der im eingebaute n Zustand des Schlosshalters mit einer Drehfalle eines Schlosses in Eingriff kom mt, eine spezielle Oberflächenstruktur in Form von Rillen oder Rändelungen vorgesehen werden, um auf diese Weise störende Gerä uschbelastungen wie z.B . narzen zu verhindern. Um eine hinreichende Stabilität des Schlosshalters zu erzielen, ü bersteigt die Stärke des Schlossbügels die Stärke der Grundplatte, vorzugsweise mindestens u m das Zweifache. Der Schlosshalter ist da nn in optimaler Weise an die Beanspruchungen beim Einsatz ausgelegt. Die Stärke der Grundplatte ist bevorzugt wenigstens 1 mm, so zum Beispiel im Durchschnitt 3 mm. Im Folgenden wird die Erfindung anhand von Ausführungsbeispielen näher erläutert. Es zeigen: In order to further improve the properties of the surface, such as size, in a further embodiment of the method, after the forming operation of the lock holder, a surface treatment, in particular a flat embossing, smooth embossing or stamping, is carried out. It is also possible to finish certain areas of the lock holder by surface treatment. For example, a special surface structure in the form of grooves or knurls can be provided at the area which engages in the built-in state of the lock holder with a catch of a lock, in order to avoid disturbing noises, such as, for example. Preventing narcotics. In order to achieve a sufficient stability of the lock holder ü ü exceeds the strength of the lock bracket, the strength of the base plate, preferably at least two times. The lock holder is there nn in optimal Way designed for the stresses during use. The thickness of the base plate is preferably at least 1 mm, for example 3 mm on average. In the following the invention will be explained in more detail by means of exemplary embodiments. Show it:

Der in den Fig.l bis Fig. 2 dargestellte Schlosshalter 1 stellt einen typischen Anwendungsfall für die vorschlagsgemäße Lösung dar. Im Folgenden wird die vorschlagsgemäße Lösung anhand eines Schlosshalters für ein Kraftfahrzeugschloss erläutert. Dies ist jedoch nicht beschränkend zu verstehen. Der in Fig.1 dargestellte Schlosshalter weist eine Grundplatte 2 und einen Schlossbügel 3 auf. Der Schlossbügel 3 weist mittig eine Ausnehmung 5 auf, um im eingebauten Zustand einen Eingriff mit einer Drehfalle eines Schlosses zu ermöglichen. Die Ausnehmung 5 kann bereits beim Umformvorgang des Ausgangsrohlings 11 durch entsprechende Werkzeuge geformt werden oder in einem nachgelagerten Bearbeitungsschritt wie z.B. durch Ausstanzen oder Spanen. Am Schlossbügel 3 sind zwei Schenkel~6-_an beiden Seiten der Ausnehmung 5 angeordnet, die mit der Grundplatte 2 in Verbindung stehen. Die Grundplatte 2 weist in diesem Fall zwei Aussparungen 4 in Form von Bohrungen auf, die konusförmig ausgebildet sind und eine Befestigung beispielsweise an eine Karosserie eines Fahrzeugs ermöglichen. Der Bereich zwischen Grundplatte 2 und Schlossbügel 3, also der Grundplatte-Bügel-Übergang 7 ist bevorzugt verstärkt ausgeführt zum Zweck der konstruktiven Versteifung. Im oberen Bereich des Schlossbügels 3 und zwar an den Übergängen zu den jeweiligen Schenkeln 6 sind bevorzugt Bügel-Schenkel-Übergänge 9 mit Übergangsradien vorgesehen, um die Herstellung des Schlosshalters 1 für eine verringerte Werkzeugbeanspruchung geeignet zu optimieren. Die abgerundeten Bügel-Schenkel-Übergänge 9 können besonders vorteilhaft beim Kaltumformen ausgebildet werden. Der Durchmesser der Grundplatte 2 ist insbesondere je nach Ausgestaltung des Ausgangsrohlings 11 nicht größer als 50 mm oder alternativ 60 mm bis 80 mm. The lock holder 1 shown in FIGS. 1 to 2 represents a typical application for the solution according to the proposal. In the following, the proposed solution will be explained with reference to a lock holder for a motor vehicle lock. However, this is not restrictive. The lock holder shown in Figure 1 has a base plate 2 and a lock bracket 3. The lock bracket 3 has a recess 5 in the center in order to enable engagement with a rotary latch of a lock when installed. The recess 5 can already be formed during the forming process of the starting blank 11 by appropriate tools or in a downstream processing step such as by punching or machining. On the lock bracket 3 are two legs ~ 6-_an arranged on both sides of the recess 5, which are in communication with the base plate 2. The base plate 2 has in this case two recesses 4 in the form of holes which are cone-shaped and allow attachment, for example, to a body of a vehicle. The area between base plate 2 and lock bracket 3, so the Baseplate-bracket transition 7 is preferably made reinforced for the purpose of constructive stiffening. In the upper area of the lock bracket 3, specifically at the transitions to the respective legs 6, bracket-leg transitions 9 with transition radii are preferably provided in order to optimize the manufacture of the lock bracket 1 in a suitable manner for a reduced tool load. The rounded bracket-leg transitions 9 can be formed particularly advantageous during cold forming. The diameter of the base plate 2 is in particular, depending on the configuration of the starting blank 11, not greater than 50 mm or alternatively 60 mm to 80 mm.
Wie aus Fig. 2 a) ersichtlich, sind die Aussparungen 4 insbesondere randseitig auf gegenüberliegenden Seiten der Grundplatte 2 angeordnet. In diesem Fall weisen die Aussparungen einen Abstand von 30 mm zueinander auf. Die Stärke 13 der Grundplatte 2 ist bevorzugt wenigstens 3 mm, bevorzugt 5 mm, noch bevorzugter 4 mm. Um eine konstruktiv stabile Verbindung mit dem Schlossbügel 3 zu erhalten, ist der Grundplatte-Bügel-Übergang 7 verstärkt ausgeführt, so dass sich die Stärke der Grundplatte 2 in diesem Bereich erhöht. Die Stärke 14 des Schlossbügels 3 ist bevorzugt größer als die Stärke 13 der Grundplatte 2, vorzugsweise um mehr als das Zweifache, um eine beanspruchungsgerechte Kraftaufnahme durch den Schlossbügel 3 sicherzustellen. As can be seen from FIG. 2 a), the recesses 4 are arranged in particular on the edge side on opposite sides of the base plate 2. In this case, the recesses have a distance of 30 mm from each other. The thickness 13 of the base plate 2 is preferably at least 3 mm, preferably 5 mm, more preferably 4 mm. In order to obtain a structurally stable connection with the lock bracket 3, the base plate bracket transition 7 is made reinforced, so that increases the strength of the base plate 2 in this area. The thickness 14 of the lock bracket 3 is preferably greater than the thickness 13 of the base plate 2, preferably more than twice, to ensure a stress-based power consumption by the lock bracket 3.
Fig. 2 b) verdeutlicht, wie sich die Stärke 13 der Grundplatte 2 im Grundplatte-Bügel-Übergang 7 erhöht. Die Höhe 10 des Schlossbügels 3 ist bevorzugt kleiner als der Durchmesser 8 der Grundplatte. Insbesondere ist die Höhe 10 des Schlossbügels nicht größer als 50 mm, so zum Beispiel 34 mm. Besondere Bedeutung kommt vorliegend dem Herstellu ngsverfahren des in den Fig . 1 bis Fig. 2 dargestellten Schlosshalters 1 zu. Nach diesem Herstellungsverfahren ist es so, dass ein Ausgangsrohling 1 1 im Wese ntlichen block- oder zylinderförmig ausgebildet ist, und zwar derart, dass mit der Kaltumformung eine Kaltverfestigung erfolgt. Fig. 2 b) illustrates how the strength of the base plate 13 2 increases in the base plate bracket transition 7. The height 10 of the lock bracket 3 is preferably smaller than the diameter 8 of the base plate. In particular, the height 10 of the lock bracket is not greater than 50 mm, such as 34 mm. Of particular importance in the present case is the production method of the method shown in FIGS. 1 to Fig. 2 lock holder 1 shown. According to this production method, it is such that a starting blank 1 1 in the Wese ntlichen block-shaped or cylindrical is formed, in such a way that takes place with the cold forming a strain hardening.
Bei dem Ausgangsrohling 1 1 handelt es sich bevorzugt um einen Draht bzw. Profildraht, der insbesondere kaltgestaucht oder kaltgepresst wurde. Der Ausgangsrohling weist bevorzugt ein quadratisches, rechteckiges oder rundes Profil auf, wobei die Aufzählung nicht beschrä nkt gemeint ist, sondern beliebige dem Herstellungsvorgang ents prechende Formen aufweisen kann, wie z. B. ovale Profile. Durch die geeig net dimensionierte Formgebung des Ausgangsrohlings 1 1 wird gezielt eine Kaltumformung bewirkt, die mit einer entsprechenden Erhöh u ng der Festigkeit im Schlosshalter 1 verbunden ist, ohne dass eine ungewünschte hohe Werkzeugbeanspruchung auftritt. The starting blank 1 1 is preferably a wire or profile wire which has been cold-pressed or cold-pressed in particular. The starting blank preferably has a square, rectangular or round profile, wherein the list is not limited, but may have any of the manufacturing process entspielte ents, such. B. oval profiles. Due to the appro net dimensioned shape of the starting blank 1 1 cold working is selectively effected, which is connected to a corresponding increase u ng the strength in the lock holder 1 without an undesirable high tool stress occurs.
Vor diesem Hintergrund verdeutlicht Fig. 3 a) einen im Wesentlichen blockförmigen Ausgangsrohling. Die Breite 1 2 des Ausgangsrohlings 1 1 ist bevorzugt 1 5 mm bis 35 mm. Die Länge 1 3 ist bevorzugt 30 mm bis 45 m m . Die H öhe 1 4 ist bevorzugt 25 mm bis 45 mm. Die Quersch nittsfläche bzw. die Profilfläche des Ausgangsrohlings 1 1 ergibt sich aus Breite 1 2 und Länge 1 3 d es Ausgangsrohlings 1 1 . Der daraus umgeformte Schlosshalter 1 weist dann bevorzugt eine Grundplatte 2 mit einem Durchmesser von nicht mehr als 50 mm auf. Against this background, FIG. 3 a) illustrates a substantially block-shaped starting blank. The width 1 2 of the starting blank 1 1 is preferably 1 5 mm to 35 mm. The length 1 3 is preferably 30 mm to 45 m m. The height 1 4 is preferably 25 mm to 45 mm. The Quersch nittsfläche or the profile surface of the starting blank 1 1 results from width 1 2 and length 1 3 d it starting blank 1 1. The formed therefrom lock holder 1 then preferably has a base plate 2 with a diameter of not more than 50 mm.
Fig. 3 b) verdeutlicht einen im Wesentlichen zylinderförmigen Ausga ngsrohling 1 1 . Der Durchmesser 1 5 des Ausgangsrohlings 1 1 ist bevorzugt 1 5 mm bis 35 mm. Die Querschnittsfläche bzw. die Profilfläche des Ausgangsrohlings 1 1 wird durch den Durchmesser 1 5 festgelegt. Die Höh e 1 4 ist bevorzugt 30 m m bis 60 mm. Der umgeformte Schlosshalter 1 weist dann bevorzugt einen Durchmesser von 60 mm bis 80 mm, so zum Beispiel 70 mm auf. Fig. 3 b) illustrates a substantially cylindrical Ausga ngsrohling 1 1. The diameter 1 5 of the starting blank 1 1 is preferably 1 5 mm to 35 mm. The cross-sectional area or the profile surface of the starting blank 1 1 is determined by the diameter 1 5. The height e 1 4 is preferably 30 mm to 60 mm. The formed lock holder 1 then preferably has a diameter of 60 mm to 80 mm, such as 70 mm.
Es hat sich gezeigt, dass auf diese Weise hergestellte Schlosshalter 1 den erforderlichen Zugbeanspruchungen standhalten. Die Schlosshalter 1 halten so einer Zugbeanspruchung von 22 kN stand, ohne dass die Schlosshalter 1 einer zusätzlichen Wärmebehandlung unterzogen wurden. Darüber hinaus liegen die Festigkeitswerte nach dem Umformvorgang bei ca.740 MPa bis 835 MPa. It has been found that lock retainers 1 produced in this way can withstand the required tensile stresses. The lock holder 1 thus withstand a tensile stress of 22 kN, without the lock holder 1 were subjected to an additional heat treatment. In addition, the strength values after the forming process are approximately 740 MPa to 835 MPa.
Besonders gute Ergebnisse lassen sich ferner durch eine Wärmebehandlung des Schlosshalters beispielsweise durch Vergüten erzielen. Die auf diese Weise vergüteten Schlosshalter 1 halten einer Zugbeanspruchung von wenigstens 30 kN stand. Die Festigkeitswerte liegen dann bei ca. 920 MPa bis 990 MPa. Durch geeignete Wärmebehandlung insbesondere Vergüten werden so hergestellte Schlosshalter 1 folglich besonders hohen Anforderungen gerecht. Particularly good results can be further achieved by heat treatment of the lock holder, for example by tempering. The lock holders 1 tempered in this way withstand a tensile load of at least 30 kN. The strength values are then about 920 MPa to 990 MPa. By suitable heat treatment, in particular tempering lock holder 1 thus produced are therefore particularly high requirements.
