Die Platine 1 wird in nachstehend beschriebenen Verfahrensschritten zu einem Bauteil einer Maschinenverkleidung verarbeitet, das an mindestens einer Seite eine Seitenwand 13, eine Bördelwand 14 sowie eine umlaufende Einsenkung 10 aufweist, in der ein Dichtelement 9, vorzugsweise ein elastischer umlaufender Gummi, angeordnet ist. Die in der Seitenwand 13 und der Bördelwand 14 vorgesehenen Öffnungen 15 bis 18 sind deckungsgleich übereinanderliegend, so daß die Maschinenverkleidung bzw. das Bauteil mit einem zugehörigen Seitengestell 22 verbunden werden kann. Der Herstellungsprozeß erfolgt wie folgt: Es wird ein in der Umformtechnik, speziell in der Blechumformung an sich bekanntes Werkzeug zum Winkelbiegen von Platine 1 verwendet. Das Werkzeug besteht gemäß Fig. 2 im wesentlichen aus einem Stempel 3 und einer zugeordneten Matrize 4. Der Stempel 3 ist an einem Stempelhalter 2 befestigt und die Matrize 4 besitzt ein Biegegesenk mit einem Matrizenprofil 5 in U-Form, welche in Richtung des Stempels 3 in eine V-Form übergeht. Weiterhin ist der Matrize 4 ein beweglicher Anschlag 6 (Fig. 2, 6, 9, 11) zugeordnet und mindestens eine Seitenfläche der Matrize 4 ist als Anschlag 7 (Fig. 7) ausgebildet. Der Stempelhalter 2 weist eine Fläche 30 auf, die planparallel zur Oberfläche der Matrize 4 angeordnet ist.A board 1 is as a sheet metal blank of a flat preform Starting material for a machine casing in FIG. 1 shown. The circuit board 1 is in a previous processing phase already with all necessary openings, e.g. in the form of Notches 15, bores 16 or openings 17 are provided been. The processing can e.g. by punching, with laser beam or cutting tools (drills, milling cutters etc.) on which should not be discussed further. The board 1 is shown in the following described method steps for a component of a Machine cladding processed on at least one side a side wall 13, a flange 14 and a circumferential Countersink 10 in which a sealing element 9, preferably a elastic circumferential rubber, is arranged. The one in the side wall 13 and the flange 14 are provided openings 15 to 18 overlapping, so that the machine cladding or the component is connected to an associated side frame 22 can be. The manufacturing process is as follows: It becomes one in forming technology, especially in sheet metal forming known tool for angular bending of board 1 used. 2 essentially consists of a stamp 3 and an associated die 4. The stamp 3 is on one Stamp holder 2 attached and the die 4 has a bending die with a die profile 5 in a U-shape, which in the direction of Stamp 3 changes into a V-shape. Furthermore, the die 4 is a movable stop 6 (Fig. 2, 6, 9, 11) assigned and at least one side surface of the die 4 is designed as a stop 7 (FIG. 7). The stamp holder 2 has a surface 30 which is plane-parallel is arranged to the surface of the die 4.

Die Platine 1 wird gegen den Anschlag 6 positioniert, derart, daß der Stempel 3 über einer Biegelinie 12 der Platine 1 steht (Fig. 2). Der Stempel 3 dringt mit der Platine 1 in die Matrize 4 ein, ein Winkel wird gebogen, so daß die Bördelwand 14 entsteht (Fig. 3). Der Stempel 3 wird aus der Matrize 4 zurückbewegt und parallel zur freiliegenden Seitenfläche der Matrize 4 vertikal bewegt, derart, daß eine Fläche 30 des Stempelhalters 2 die Bördelwand 14 entlang der Biegelinie 12 planparallel zur Platine 1 biegt (Fig. 4, 5). Der Stempel 3 dient dabei gleichzeitig als Anschlag. Die Öffnungen in Form von Ausklinkungen 15, Bohrungen 16 oder Langlöchern 18 sind somit deckungsgleich. Die auf der Matrize 4 aufliegende Platine 1 wird weiter gegen den Anschlag 6 bewegt bis zur Position der vorgesehenen Einsenkung 10. Der Stempel 3 wird auf die Platine 1 zubewegt und biegt die Einsenkung 10 in einem Winkel, der abhängig von der Dicke der Platine 1 und der Matritzenform ist (Fig. 6). Anschließend wird die Platine 1 im Werkzeug gedreht und auf der Rückseite wird entlang der Biegelinie 11 (Fig. 1) die Seitenwand 13 von der Platine 1 abgewinkelt. Dabei wird eine Seitenfläche der Matrize 4 als Anschlag 7 genutzt (Fig. 7, 8). Damit ist die erste Seite der Platine 1 gefertigt. Die gegenüberliegende Seite der Platine 1 wird gemäß Fig. 9 gegen den Anschlag 6 bewegt und der Stempel 3 biegt im vorliegenden Beispiel im rechten Winkel die Versteifungswand 24 (Fig. 10). Gemäß Fig. 11 und 12 wird die Seitenwand 13 rechtwinklig zur Platine 1 gebogen. Die zweite Seite der Platine 1 ist fertig (Fig. 13). Die Platine 1 wird nun an den Biegelinien 19 und 20 abgewinkelt und das fertige Bauteil kann mit benachbarten Bauteilen 27, 28 sowie 29 als Verkleidung 8 verbunden werden.The board 1 is positioned against the stop 6 in such a way that the stamp 3 is above a bending line 12 of the board 1 (Fig. 2). The stamp 3 penetrates with the circuit board 1 into the die 4 on, an angle is bent so that the flare 14 is formed (Fig. 3). The stamp 3 is moved back out of the die 4 and parallel to the exposed side surface of the die 4 vertically moves such that a surface 30 of the punch holder 2 the flare 14 along the bending line 12 plane-parallel to the circuit board 1 bends (Fig. 4, 5). The stamp 3 also serves as Attack. The openings in the form of notches 15, bores 16 or elongated holes 18 are thus congruent. The one on the die 4 resting board 1 is moved against the stop 6 until to the position of the intended depression 10. The stamp 3 is on moves the board 1 and bends the depression 10 at an angle, which is dependent on the thickness of the board 1 and the shape of the die (Fig. 6). Then the board 1 is rotated in the tool and on the back along the bending line 11 (Fig. 1) Sidewall 13 angled from the board 1. Doing so Side surface of the die 4 used as a stop 7 (Fig. 7, 8). The first side of the circuit board 1 is thus produced. The opposite 9 of the circuit board 1 is against the stop 6 moved and the stamp 3 bends in the present example on the right Angle the stiffening wall 24 (Fig. 10). 11 and 12 the side wall 13 is bent at right angles to the circuit board 1. The second Side of the board 1 is finished (Fig. 13). The board 1 is now on the bending lines 19 and 20 angled and the finished component can with adjacent components 27, 28 and 29 as cladding 8 get connected.
