Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen ei nes zumindest zweilagigen Stahlblech-Formteiles mit zu mindest einer schalldämmenden Zwischenschicht. Derar tige Stahlblech-Formteile werden beispielsweise im Au tomobilbau eingesetzt.The invention relates to a method for producing egg nes at least two-layer steel sheet molded part with at least one soundproofing intermediate layer. Derar sheet steel parts are, for example, in the Au tomobilbau used.
Bekannt sind beispielsweise die sog. Antiphon-Bleche, die von einem Hersteller für schallgedämmte Doppelble che als Meterware geliefert und später in die ge wünschte Form tiefgezogen werden. Diese Antiphonbleche stellen im wesentlichen ein zweilagiges Doppelblech mit zwischenliegender Schalldämmschicht dar. Diese Schall dämmschicht haftet an den Blechoberflächen und fixiert somit die beiden Blechlagen des Doppelbleches relativ zueinander.For example, the so-called antiphon sheets are known, from a manufacturer of soundproof double sheets che delivered by the meter and later in the ge desired shape are deep drawn. These antiphon sheets essentially provide a two-layer double sheet intermediate soundproofing layer. This sound insulation layer adheres to the sheet metal surfaces and is fixed thus the two sheet layers of the double sheet relative to each other.
Da die Verwendung derartiger vorgefertigter Schalldämm bleche bei der anschließenden Fertigung des Stahlblech- Formteiles zu übermäßig hohem Verschnitt führen kann, hat sich die Erfindung die Aufgabe gestellt, ein Her stellverfahren aufzuzeigen, das einen geringeren Res sourcenbedarf aufweist.Since the use of such prefabricated sound insulation sheets during the subsequent production of the steel sheet Molded part can lead to excessively high waste, the invention has set itself the task of a Her to show adjustment procedures that a lower res has resource requirements.
Zur Lösung dieser Aufgabe ist vorgesehen, daß auf eine erste Blechlage punktuell oder bereichsweise schalldäm mendes Material aufgebracht und hierauf eine weitere Blechlage aufgelegt wird, wonach die Blechlagen mitein ander verbunden werden. Hierdurch entsteht ein mehrla giges Stahlblech, das anschließend durch Tiefziehen ge formt wird, wobei das schalldämmende Material zumindest teilweise zwischen den Blechlagen verteilt wird.To solve this problem it is provided that on a The first sheet layer is soundproof at certain points or in some areas Material applied and then another Sheet metal layer is placed, after which the sheet metal layers together be connected. This creates a multi steel sheet, which is then ge by deep drawing is formed, the sound-absorbing material at least is partially distributed between the sheet layers.
Ein Aspekt dieses Verfahrens ist es, daß das schalldäm mende Material nicht über der gesamten Blechoberfläche aufgebracht werden muß, sondern gezielt vorrangig an den Stellen, an denen auch eine optimale Schalldämmwir kung erzielt wird. Darüber hinaus kann ein schalldäm mendes Material zum Einsatz kommen, das im Hinblick auf seine schalldämmenden Eigenschaften optimiert ist. Zu sätzliche Eigenschaften, wie beispielsweise Hafteigen schaften unter Einbehaltung einer gewissen Viskosität muß das Schalldämmaterial dagegen nicht aufweisen, da zur Fixierung der Blechlagen untereinander diese mit einander verbunden werden. Ein Aspekt der Erfindung ist auch, daß die schalldämmende Zwischenschicht quasi durch das Tiefziehen aufgebaut wird, indem durch die Verformung der Blechlagen das schalldämmende Material zumindest teilweise von den ursprünglichen punktuellen oder bereichsweisen Auftragstellen verdrängt wird.One aspect of this method is that the soundproof material not over the entire sheet surface must be applied, but primarily with priority the places where there is also optimal sound insulation kung is achieved. In addition, a soundproof material that is used with regard to its soundproofing properties is optimized. To additional properties, such as adhesive dough with a certain viscosity on the other hand, the soundproofing material does not have to have, since to fix the sheet metal layers with each other to be connected. One aspect of the invention is also that the sound-absorbing intermediate layer quasi is built up by deep drawing by Deformation of the sheet metal layers the soundproofing material at least partially from the original punctual ones or area-by-area order sites.
Vorteilhafterweise können durch Anwendung dieses Ver fahrens Stahlblechlagen zum Einsatz kommen, die in ih ren Abmessungen dem Formteil bereits angepaßt sind. Ebenso ist es möglich, die einzelnen Stahlblechlagen vor dem Aufbringen des schalldämmenden Materials und vor dem Tiefziehen beispielsweise durch Ausstanzen mit Aussparungen zu versehen, die am fertigen Formteil bei spielsweise zur Aufnahme von Anbauteilen erforderlich sind.Advantageously, by using this Ver driving sheet steel layers are used, which in ih ren dimensions of the molding are already adjusted. It is also possible to use the individual sheet steel layers before applying the sound absorbing material and before deep drawing, for example by punching out To provide recesses in the finished molded part for example necessary to hold attachments are.
Die bereits oben angesprochene Verbindung der Blechla gen untereinander erfolgt vorzugsweise durch Punkt schweißen. Möglicherweise empfiehlt es sich in diesem Zusammenhang, beim Auftragen des schalldämmenden Mate rials auf die erste Blechlage die späteren Punkt schweißbereiche bereits auszusparen. Ein bevorzugtes Verfahren zum punktuellen bzw. bereichsweisen Auftragen des schalldämmenden Materiales arbeitet dabei nach ei nem Siebdruck-Verfahren. Als schalldämmendes Material können dabei Silikone oder PVC-Pasten, aber beispiels weise auch Polypropylen oder Polyethylen zum Einsatz kommen.The already mentioned connection of the Blechla mutually is preferably done by point welding. It may be recommended in this Connection, when applying the sound-absorbing mate rials on the first sheet layer the later point already cut out welding areas. A preferred one Process for selective or area-by-area application the soundproofing material works according to egg screen printing process. As a sound-absorbing material can be silicone or PVC pastes, but for example also use polypropylene or polyethylene come.
Ein Ausführungsbeispiel für die Erfindung ist nicht ge zeigt, da es anhand obiger Erläuterungen dem Fachmann möglich sein müßte, ein zumindest zweilagiges Stahl blech-Formteil mit zumindest einer schalldämmenden Zwi schenschicht nach einem erfindungsgemäßen Verfahren zu fertigen.An embodiment of the invention is not ge shows that it is based on the above explanations to the expert should be possible, at least a two-layer steel sheet metal molded part with at least one soundproofing intermediate layer by a method according to the invention manufacture.
