Abstract

The object of the invention is a process for manufacturing a formed body made by pressing or deep-drawing and having different wall thicknesses from an initially flat sheet metal part. Such a formed body, for example a beam (1), having a thicker central area (1a) with a thicker wall, and areas (1b) with reduced wall thicknesses, is produced from a sheet metal part in a single piece with a thickness which corresponds to the largest wall thickness of the formed body (1) to be produced. Before being pressed or deep-drawn, the thickness of the sheet metal part is reduced down to the desired lower thickness exclusively in those areas where the formed body should present a lower wall thickness by rolling out or by another similar drawing out process. Material requirements and the weight of the formed body (1) are thus reduced during production, and at the same time a stable and highly load-resistant formed body is obtained, as the quality of the base material is not affected, as is for example the case when the formed body is soldered together from sheet metal parts having different strengths or thicknesses.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines durch Pressen oder Tiefziehen gefertigten Formkörpers mit unterschiedlichen Wandstärken aus einem zunächst ebenen Blech­ teil.The present invention relates to a method for manufacturing a molded body produced by pressing or deep drawing different wall thicknesses from an initially flat sheet part.

Aus Blech hergestellte Formkörper sind je nach Anwendungsfall in verschiedenen Bereichen unterschiedlich starken Belastungen unterworfen. Aus diesem Grunde ist es bekannt, derartige Form­ körper mit unterschiedlichen Wandstärken zu versehen, um auf diese Weise einerseits den zu erwartenden Belastungen gerecht zu werden und andererseits entsprechend Material einzusparen.Shaped bodies made of sheet metal are depending on the application different levels of stress in different areas subject. For this reason it is known to form such body with different wall thicknesses in order to this way, on the one hand, to meet the expected loads to become and on the other hand to save material accordingly.

Bislang hat man derartige Formkörper entweder aus einzelnen, schon verformten Blechteilen unterschiedlicher Wandstärke zu­ sammengeschweißt oder unterschiedlich dicke Blechteile zunächst zusammengeschweißt und dann insgesamt entsprechend verformt.So far, such shaped bodies have either been made up of individual already deformed sheet metal parts of different wall thickness welded together or sheet metal parts of different thickness initially welded together and then deformed accordingly.

In beiden Fällen ist es also erforderlich, Schweißarbeiten aus­ zuführen.So in both cases it is necessary to carry out welding work respectively.

Abgesehen von den dadurch verursachten zusätzlichen Kosten ist eine Schweißnaht immer eine potentielle Schwachstelle.Aside from the additional cost involved a weld seam is always a potential weak point.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Ver­ fahren der gattungsgemäßen Art zu schaffen, nach dem ein Formkörper in material- und gewichtssparender Bauweise unter Vermeidung jedweder Schweißarbeiten herstellbar ist.The present invention has for its object a Ver drive of the generic type to create after the Shaped body in material and weight-saving design under Avoidance of any welding work can be produced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein ein­ stückiges Blechteil mit einer der größten Wandstärke des zu fertigenden Formkörpers entsprechenden Dicke verwendet und vor dem Pressen oder Tiefziehen ausschließlich in denjenigen Bereichen, in denen der Formkörper eine geringere Wandstärke aufweisen soll, durch Auswalzen oder entsprechende andere Streckverfahren auf die gewünschte geringere Dicke reduziert wird.This object is achieved in that a piece sheet metal part with one of the greatest wall thickness of the manufacturing molding used corresponding thickness and before pressing or deep drawing only in those Areas in which the molded body has a smaller wall thickness should have, by rolling or other appropriate Stretching process reduced to the desired smaller thickness becomes.

Ein nach diesem Verfahren hergestellter Formkörper zeichnet sich dadurch aus, daß die Eigenschaften des Ausgangsmaterials in keiner Weise beeinträchtigt werden und daß zusätzliche, auf­ wendige Schweißarbeiten und Nachbearbeitungen der Schweißnähte vermieden werden.A molded article produced by this process is drawn is characterized by the fact that the properties of the starting material not be affected in any way and that additional, on agile welding and reworking of the weld seams be avoided.

Es ist ohne weiteres möglich, die Reduzierung auf eine geringere Dicke stufig vorzunehmen oder stufenlos durchzu­ führen.It is easily possible to reduce it to one to make smaller thicknesses in stages or continuously to lead.

Durch die Dickenreduzierung des einstückigen Blechteiles vor seiner Verformung wird eine entsprechende Materialeinsparung bei der Herstellung eines Formkörpers erzielt, einhergehend mit einer entsprechenden Gewichtsreduzierung.By reducing the thickness of the one-piece sheet metal part its deformation will result in a corresponding saving in material achieved in the manufacture of a molded article, along with a corresponding weight reduction.

Der natürliche Faserverlauf des einstückigen Blechteiles wird in keiner Weise unterbrochen, worin ein Vorteil gegenüber ver­ schweißten Bauteilen zu sehen ist. The natural grain of the one-piece sheet metal part becomes in no way interrupted, which is an advantage over ver welded components can be seen.  

Anhand der beigefügten Zeichnungen wird das erfindungsgemäße Verfahren im folgenden noch einmal ausführlich erläutert.Based on the accompanying drawings, the invention The procedure is explained in detail below.

Fig. 5 to 7 are schematic diagrams for Verdeut lichung various possibilities of a reduction in thickness of the starting material for the production of a molding.

In den Fig. 1 bis 3 ist als Beispiel für einen Formkörper im Sinne der vorliegenden Erfindung ein Träger 1 dargestellt, der aus einem zunächst ebenen Blechteil durch Pressen oder Tief­ ziehen gefertigt worden ist. In Figs. 1 to 3, a carrier 1 is shown as an example of a shaped body according to the present invention which has been made move from one of initially flat sheet metal part by pressing or deep.

Dieser Träger 1 weist in seinem mittleren Bereich 1a eine größere Wandstärke auf als in seinen beiden äußeren Bereichen 1b. Dies zeigt die Einzelheit gemäß Fig. 4 besonders an­ schaulich.This carrier 1 has a larger wall thickness in its central region 1 a than in its two outer regions 1 b. This shows the detail according to FIG. 4 particularly clearly.

Der Träger 1 ist aus einem einstückigen Blechteil hergestellt, dessen Dicke der größten Wandstärke des mittleren Bereiches 1a des Trägers 1 entspricht. Vor dem Pressen oder Tiefziehen dieses Ausgangsmateriales ist das Blechteil in den späteren Bereichen 1b des Trägers durch Auswalzen oder entsprechende Streckverfahren auf die gewünschte geringere Dicke reduziert worden.The carrier 1 is made from a one-piece sheet metal part, the thickness of which corresponds to the greatest wall thickness of the central region 1 a of the carrier 1 . Before pressing or deep-drawing this starting material, the sheet metal part in the later areas 1 b of the carrier has been reduced to the desired smaller thickness by rolling or corresponding stretching processes.

Die Fig. 5 bis 7 zeigen in schematischer Darstellung, welche Möglichkeiten der Dickenreduzierung beim Auswalzen gegeben sind. Figs. 5 to 7 show in a schematic representation, the possibilities are given to the reduction in thickness during rolling.

Fig. 5 veranschaulicht, daß das Blechteil, welches im allge­ meinen auch als Platine bezeichnet wird und in den Fig. 5 bis 7 mit dem Bezugszeichen 2 versehen ist, von seinen Enden ausgehend bis auf eine bestimmte Länge in einen Walzenstuhl 3 eingeschoben werden kann, wobei anschließend entweder eine Walzrichtungsumkehr oder ein Öffnen des Walzenstuhles erfolgt. Fig. 5 illustrates that the sheet metal part, which is generally referred to as a board and is provided with the reference number 2 in Figs. 5 to 7, can be inserted from its ends up to a certain length into a roller mill 3 , whereby either a reversal of the rolling direction or an opening of the roller mill takes place.

Fig. 6 zeigt, daß die bereichsweise Dickenreduzierung einer Platine 2 auch dadurch erfolgen kann, daß die Platine 2 insgesamt durch den Walzenstuhl 3 hindurchgeschoben wird, wobei der Walzenabstand verändert werden kann. Fig. 6 shows that the reduction in thickness of a blank 2 can also take place in that the blank 2 is pushed as a whole through the roller mill 3 , it being possible to change the roller spacing.

Hierdurch ist es auch möglich, eine kontinuierliche Dickenre­ duzierung vorzunehmen. This also makes it possible to have a continuous thickness reduction.  

Wie aus Fig. 7 hervorgeht, kann eine Platine auch durch einen Walzenstuhl 3 mit Profilwalzen 4 geschoben werden, um eine bereichsweise Reduzierung der Ausgangsdicke zu erzielen.As can be seen from FIG. 7, a blank can also be pushed through a roller mill 3 with profile rollers 4 in order to achieve a reduction in the initial thickness in some areas.

Die Dickenreduzierung kann, wie aus den Fig. 5 bis 7 hervor­ geht, an der vorgefertigten Platine 2 erfolgen, bei einfachen Bauteilen besteht auch die Möglichkeit, daß eine Blechdicken­ reduzierung nach dem Schema der Fig. 6 und 7 am abge­ wickelten Coil erfolgen kann, wobei dann anschließend eine Trennung der Platinen vom Coil erfolgt.The thickness reduction can, as can be seen from FIGS. 5 to 7, take place on the prefabricated circuit board 2 ; in the case of simple components there is also the possibility that a reduction in sheet thickness according to the diagram of FIGS . 6 and 7 can take place on the unwound coil, the boards then being separated from the coil.
