re, so daß vergleichsweise hohe Materialkosten anfallen. Üblicherwei¬ se werden zur Herstellung der Abblendkappen aus einem Blech oder einem Blechstreifen eine Vielzahl von Abblendkappen reihenweise geformt und ausgestanzt. Dabei ist der Abstand zwischen zwei auf- einanderfolgenden Abblendkappen beim Ausstanzen größer als die größte Längenabmessung der Abblendkappe, so daß bei der Herstel¬ lung der Abblendkappen ein relativ hoher Anteil des Blechs unge¬ nutzt als Verschnitt zurückbleibt.re, so that comparatively high material costs are incurred. In order to produce the anti-dazzle caps from a sheet metal or a sheet metal strip, a plurality of anti-dazzle caps are usually formed and punched out in rows. The distance between two successive anti-glare caps when punching out is greater than the greatest length dimension of the anti-glare cap, so that a relatively high proportion of the metal sheet remains unused as waste when the anti-glare caps are produced.
Es ist die Aufgabe der Erfindung, eine kostengünstige, materialspa- rende Abschattungsvorrichtung für eine Kraftfahrzeuglampe bereit¬ zustellen und ein Herstellungsverfahren für eine derartige Abschat¬ tungsvorrichtung anzugeben.It is the object of the invention to provide an inexpensive, material-saving shading device for a motor vehicle lamp and to specify a manufacturing method for such a shading device.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale der Patentansprüche 1 bzw. 3 gelöst. Besonders vorteilhaf- te Ausführungen der Erfindung sind in den Unteransprüchen be¬ schrieben.According to the invention, this object is achieved by the characterizing features of claims 1 and 3, respectively. Particularly advantageous embodiments of the invention are described in the subclaims.
Bei der erfindungsgemäßen Abschattungsvorrichtung ist die Schweißfahne mit einer Aussparung versehen, deren Gestalt im we¬ sentlichen durch die Form eines der Schweißfahne gegenüberliegen- den Wsmdbereiches der Abschattungsvorrichtung bestimmt ist. Diese Maßnahme erlaubt eine Materialeinsparung von bis zu 15% und senkt daher die Herstellungskosten für die Abschattungsvorrichtung entsprechend, ohne daß dadurch die Funktionstüchtigkeit der Ab¬ schattungsvorrichtung beeinträchtigt wird. Außerdem erfordert das Ausstanzen und die Formgebung der erfindungsgemäßen Abschat¬ tungsvorrichtung keinen zusätzlichen Arbeitsgang. Vorteilhafterweise ist die für die Abschattung wirksame Fläche der Abschattungsvor¬ richtung gewölbt und besonders vorteilhaft wannenartig ausgebildet. Dadurch kann die Abschattungsvorrichtung derart angeordnet wer- den, daß sie den abzuschattenden Leuchtkörper von mehreren Seiten umgibt. Die erfindungsgemäße Abschattungsvorrichtung besitzt au¬ ßerdem vorteilhafterweise einen im Vergleich zu den übrigen Wand- teilen der Abschattungsvorrichtung hochgezogenen, als Abschatter- nase bezeichneten Wandbereich, der der Schweißfahne gegenüber¬ liegt. Dieser hochgezogene Wandbereich dient zur besseren Abschat¬ tung des von der Abschattungsvorrichtung abgeschatteten Leucht¬ körpers gegen einen außerhalb der Abschattungsvorrichtung ange¬ ordneten zweiten Leuchtkörper. Der Umriß bzw. der Rand der Aus- sparung in der Schweißfahne besitzt vorteilhafterweise annähernd die gleiche Form wie die auf eine Ebene projizierte Randlinie der Abschat¬ ternase. Die Schweißfahne der erfindungsgemäßen Abschattungs¬ vorrichtung ist vorteilhafterweise mit einer Querrippe versehen, die eine Buckels chweißung mit einem Ende des abgeschatteten Leucht- körpers ermöglicht. Die Aussparung in der erfindungsgemäßen Ab¬ schattungsvorrichtung erstreckt sich dabei vorteilhafterweise vom Rand der Schweißfahne bis zur Querrippe. Die verbleibenden, beid- seitig zur Aussparung angeordneten und über die Querrippe hinaus¬ ragenden Reststege der Schweißfahne genügen als Ansatz für die Greifwerkzeuge der Bestückungs- und Fertigungsautomaten.In the shading device according to the invention, the welding vane is provided with a recess, the shape of which is essentially determined by the shape of a region of the shading device opposite the welding vane. This measure allows a material saving of up to 15% and therefore lowers the manufacturing costs for the shading device accordingly, without thereby impairing the functionality of the shading device. In addition, the punching out and shaping of the shading device according to the invention do not require any additional work step. The surface of the shading device which is effective for shading is advantageously curved and, particularly advantageously, trough-shaped. As a result, the shading device can be arranged in this way that it surrounds the filament to be shaded from several sides. The shading device according to the invention also advantageously has a wall region, which is raised in comparison with the other wall parts of the shading device and is referred to as the shading nose, and which lies opposite the welding lug. This raised wall area serves for better shading of the luminous element shaded by the shading device against a second luminous element arranged outside the shading device. The outline or the edge of the recess in the welding lug advantageously has approximately the same shape as the edge line of the shading nose projected onto a plane. The welding vane of the shading device according to the invention is advantageously provided with a transverse rib, which enables a projection to be welded to one end of the shaded filament. The recess in the shading device according to the invention advantageously extends from the edge of the welding vane to the transverse rib. The remaining webs of the welding lug, which are arranged on both sides of the recess and protrude beyond the transverse rib, are sufficient as an attachment for the gripping tools of the automatic placement and production machines.
Während des erfindungsgemaßen Fertigungsprozesses werden eine Vielzahl von Abschattungsvorrichtungen reihenweise aus einem Blech geformt und ausgestanzt, wobei der Abstand zweier aufeinan¬ derfolgender Abschattungsvorrichtungen beim Ausstanzen aus dem Blech erfindungsgemäß kleiner als die größte Längenabmessung ei¬ ner Abschattungsvorrichtung ist. Dabei ist die größte Längenabmes¬ sung einer Abschattungsvorrichtung durch die Länge der längsten Seite des Rechtecks mit dem kleinsten Umfang definiert, das die auf eine parallel zur Schweißfahne verlaufende Ebene im Maßstab 1 : 1 projizierte Randlinie der Abschattungsvorrichtung — inklusive ihrer Schweißfahne — vollständig umhüllt. Beim Ausstanzen der Abschat¬ tungsvorrichtungen entsteht in der Schweißfahne jeder Abschat¬ tungsvorrichtung eine Aussparung, in die bereits die unmittelbar fol¬ gende Abschattungsvorrichtung eingreift. Die Abschatternase der nächstfolgenden Abschattungsvorrichtung wird dabei vorteilhafter¬ weise aus dem aus der Schweißfahne der unmittelbar vorhergehen¬ den Abschattungsvorrichtung ausgestanzten Blechmaterial geformt. Die Form bzw. der Rand der Aussparung in der Schweißfahne ist damit im wesentlichen durch den Umriß der Abschatternase be- stimmt.During the manufacturing process according to the invention, a multiplicity of shading devices are formed and punched out in rows from a sheet metal, the distance between two successive shading devices when punching out of the sheet metal according to the invention being smaller than the largest length dimension of a shading device. The greatest length dimension of a shading device is defined by the length of the longest side of the rectangle with the smallest circumference, which is the edge line of the shading device projected onto a plane running parallel to the welding vane on a scale of 1: 1, including its Sweat flag - completely covered. When the shading devices are punched out, a recess is formed in the welding vane of each shading device, into which the immediately following shading device already engages. The shading nose of the next shading device is advantageously formed from the sheet metal material punched out of the welding lug of the immediately preceding shading device. The shape or the edge of the recess in the welding vane is thus essentially determined by the outline of the shading nose.

Die Abblendkappe 1 des bevorzugten Ausführungsbeispiels • der Er¬ findung ist wannenartig ausgebildet. Sie besitzt einen im wesentli¬ chen flachen, mit zwei Schweißwülsten 2a versehenen Boden 2. Die Abblendkappe weist ferner eine an ihrem Rand angeformte, im we- sentlichen flache Schweißfahne 3 auf. Der der Schweißfahne 3 ge¬ genüberliegende Wandbereich 4a der Abblendkappe 1 ist im Vergleich zu den übrigen Wandbereichen 4b der Abblendkappe 1 hochgezogen und formt die sogenannte Abschatternase 4a, die die Abblendlicht- und Fernlichtglühwendel (nicht abgebildet) gegeneinander abschattet. Die für die Abschattung der Abblendlichtglühwendel wirksame Fläche wird von dem Boden 2 und den gewölbten Wandbereichen 4a, 4b der Abblendkappe 1 gebildet. Sieht man von der Schweißfahne 3 und den Schweißwülsten 2a ab, dann erinnert die Form der Abblendkappe 1 an den Rumpf eines Bootes. In diesem Vergleich wäre die Schweiß- fahne 3 an das Heck des Rumpfes angeformt und die Abschatternase 4a würde den hochgezogenen Bug des Rumpfes bilden. Die Abblend¬ kappe 1 ist spiegelsymmetrisch bezüglich der mittig, senkrecht zum Boden 2 und in Längsrichtung durch die Abblendkappe 1 verlaufen¬ den Spiegelebene A-A.The anti-dazzle device 1 of the preferred embodiment • of the invention is trough-shaped. It has an essentially flat bottom 2 provided with two welding beads 2a. The anti-dazzle device also has an essentially flat welding lug 3 formed on its edge. The wall area 4a of the anti-dazzle device 1 opposite the welding lug 3 is raised in comparison to the other wall areas 4b of the anti-dazzle device 1 and forms the so-called shading nose 4a, which shades the low-beam and high-beam incandescent filaments (not shown) against one another. The area effective for shading the low-beam incandescent filament is formed by the base 2 and the curved wall areas 4a, 4b of the anti-dazzle device 1. Apart from the welding lug 3 and the welding beads 2a, the shape of the anti-dazzle device 1 is reminiscent of the hull of a boat. In this comparison, the welding lug 3 would be formed on the stern of the fuselage and the shading nose 4a would form the raised bow of the fuselage. The anti-dazzle device 1 is mirror-symmetrical with respect to the mirror plane A-A running in the middle, perpendicular to the base 2 and in the longitudinal direction through the anti-dazzle device 1.
Die an den Rand der für die Abschattung wirksamen Fläche 2, 4a, 4b angeformte Schweißfahne 3 ist mit einer Querrippe 3a ausgestattet, die zur Buckelverschweißung mit einem Ende der Abblendlichtglüh - wendel dient. Außerdem weist die Schweißfahne 3 eine Aussparung 5 auf, die sich vom Rand der Schweißfahne 3 bis zur Querrippe 3a er- streckt. Der Rand der Aussparung 5 der Schweißfahne 3 besitzt an¬ nähernd die gleiche Form bzw. Kontur wie die auf eine Ebene proji¬ zierte Randlinie 6 der Abschatternase 4a der Abblendkappe 1. Zu beiden Seiten der Aussparung 5 verbleibt jeweils ein über die Quer¬ rippe 3a hinausragender und zur Schweißfahne 3 gehörender Steg 7a, 7b. Diese Stege 7a, 7b genügen als Ansatz für die Greifwerkzeuge der Bestückungs- und Fertigungsau tomaten. Die größte Längenab¬ messung der Abblendkappe 1 , in Längsrichtung von der Abschatter¬ nase 4a bis zur senkrecht zur Spiegelebene A-A verlaufenden Außen¬ kante der Stege 7a, 7b gemessen, mißt 12,7 mm. Die maximale Tiefe der Aussparung 5 beträgt 1 ,7 mm. Die Tiefe der wannenartigen Ab¬ blendkappe 1 beträgt, ohne Berücksichtigung der Schweißwülste 2a, ungefähr 2,7 mm. Die maximale Höhe der Abschatternase 4a beträgt vom Boden 2 aus gemessen ca. 4, 1 mm. Damit überragt die Abschat¬ ternase 4a die übrigen Wandbereiche 4b in der Höhe um ca. 1 ,4 mm.The welding lug 3 formed on the edge of the surface 2, 4a, 4b effective for shading is equipped with a transverse rib 3a, which is used for projection welding with one end of the low-beam incandescent filament. In addition, the welding lug 3 has a cutout 5 which extends from the edge of the welding lug 3 to the transverse rib 3a. The edge of the recess 5 of the welding vane 3 has approximately the same shape or contour as the edge line 6 of the shading nose 4a of the anti-dazzle cap 1 projected onto a plane. On both sides of the recess 5 there is one across the transverse rib 3a protruding web 7a, 7b belonging to the welding lug 3. These webs 7a, 7b are sufficient as an approach for the gripping tools the assembly and manufacturing machines. The largest length dimension of the anti-dazzle device 1, measured in the longitudinal direction from the shading nose 4a to the outer edge of the webs 7a, 7b running perpendicular to the mirror plane AA, measures 12.7 mm. The maximum depth of the recess 5 is 1.7 mm. The depth of the trough-like anti-dazzle device 1, without taking the welding beads 2a into account, is approximately 2.7 mm. The maximum height of the shading nose 4a, measured from the bottom 2, is approximately 4.1 mm. The shading nose 4a thus projects above the remaining wall areas 4b in height by approximately 1.4 mm.
Die erfindungsgemäßen Abblendkappen 1 , 1', 1" werden reihenweise, in gleicher Orientierung aus einem Molybdänblechstreifen 8 im glei¬ chen Arbeitsgang geformt und ausgestanzt (Fig. 4). Dabei ist der Ab¬ stand zweier unmittelbar aufeinanderfolgender Abblendkappen 1 , 1' bzw. 1', 1" kleiner als die größte Längenabmessung einer Abblend- kappe 1, 1', 1". Beim Ausstanzen entsteht in der Schweißfahne 3, 3' jeder Abblendkappe 1 , 1' eine Aussparung 5, 5', in die bereits die unmittelbar folgende Abblendkappe 1 ', 1" eingreift. Die Abschatterna¬ se 4a', 4a" der nächstfolgenden Abblendkappe 1 ', 1" wird dabei aus dem aus der Schweißfahne 3, 3' der unmittelbar vorhergehenden Abblendkappe 1, 1' ausgestanzten Blechmaterial geformt. Die Form der Aussparung 5, 5' in der Schweißfahne 3, 3' ist damit durch den Rand der Abschatternase 4a', 4a" bestimmt. Alle Abblendkappen 1 , 1', 1" sind identisch geformt. Der Rand der Aussparung 5 in der Schweißfahne 3 besitzt daher näherungsweise die gleiche Form wie die auf eine Ebene projizierte Randlinie 6 der Abschattemase 4a der Abblendkappe 1. Die Übereinstimmung gilt nur näherungsweise, weil die Abschattemase 4a während des Stanzprozesses gleichzeitig auch einem Formgebungsprozeß unterworfen wird. Die Erfindung beschränkt sich nicht auf das oben näher erläuterte Ausführungsbeispiel. Beispielsweise kann die Erfindung auch auf einen Abschatter gemäß der deutschen Patentanmeldung mit dem amtlichen Aktenzeichen 196 06 876.2 angewandt werden. The anti-dazzle caps 1, 1 ', 1 "according to the invention are formed and punched out in rows in the same orientation from a sheet of molybdenum sheet 8 in the same operation (FIG. 4). The distance between two successive anti-dazzle caps 1, 1' or 1 ', 1 "smaller than the largest length dimension of a dimming cap 1, 1', 1". When punching out, a cutout 5, 5 'is created in the welding lug 3, 3' of each dimming cap 1, 1 ', into which the immediate the following anti-dazzle cap 1 ', 1 "engages. The shading nose 4a ', 4a "of the next anti-dazzle device 1', 1" is formed from the sheet metal material punched out of the welding lug 3, 3 'of the immediately preceding anti-dazzle device 1, 1'. The shape of the recess 5, 5 'in the welding lug 3, 3' is thus determined by the edge of the shading nose 4a ', 4a ". All anti-dazzle caps 1, 1', 1" are shaped identically. The edge of the recess 5 in the welding lug 3 therefore has approximately the same shape as the edge line 6 of the shading nose 4a of the anti-dazzle device 1 projected onto a plane. The correspondence applies only approximately because the shading nose 4a is simultaneously subjected to a shaping process during the stamping process. The invention is not limited to the exemplary embodiment explained in more detail above. For example, the invention can also be applied to a shading device according to the German patent application with the official file number 196 06 876.2.
