 EMI2.1 
 Verfahren wirtschaftlich wird. Da die Bewegung des Werkzeuges nicht mehr als   1'5   bis 4   zu sein   braucht, kann die Schnelligkeit der Maschine erheblich vermehrt werden. Das Blech wird für jeden Hub der Presse um einen Schritt vorgeschoben, und die   Schrittlänge darf nicht grosser   als das ein-bis drei- fache der Dicke des Bleches sein, denn andernfalls lässt das Werkzeug Wellen an dem Blech zurück, die allerdings nur ein oder einige Hundertstel eines Millimeters hoch sind.

   Angenommen, die Presse mache 500 Hübe pro Minute und der Vorschub beträge 2   mrn   pro Hub, so wird dies jedenfalls eine Vorschub- geschwindigkeit von 1 m pro Minute oder 60   m   pro Stunde, und man ersieht daraus, dass das Richten sehr schnell vor sich geht. 



   PATENT-ANSPRÜCHE :
1. Verfahren zum Richten von Blechen, dadurch gekennzeichnet, dass das Blech mittels eines gegen dasselbe hin-und zurückbewegten Presswerkzeuges oder-werkzeugteiles, an dem es vorbeigeführt wird, in eine Reihe von Wellen gebuchtet wird, die sich annähernd winkelrecht gegen die Vorschub- richtung des Bleches erstrecken und deren Höhe beim weiteren Vorschub des Bleches allmählig ver- mindert wird, um schliesslich ganz beseitigt zu werden.

 EMI2.1
 Process becomes economical. Since the movement of the tool need not be more than 1'5 to 4, the speed of the machine can be increased considerably. The sheet is advanced by one step for each stroke of the press, and the step length must not be greater than one to three times the thickness of the sheet, otherwise the tool leaves waves on the sheet, but only one or a few Hundreds of a millimeter tall.

   Assuming the press makes 500 strokes per minute and the feed rate is 2 mm per stroke, this will in any case be a feed rate of 1 m per minute or 60 m per hour, and you can see from this that the straightening is very quick .



   PATENT CLAIMS:
1. A method for straightening sheet metal, characterized in that the sheet metal is booked into a series of waves, which are approximately at right angles to the feed direction, by means of a pressing tool or tool part moved back and forth against the same, which it is guided past of the sheet and the height of which is gradually reduced as the sheet is advanced, in order to finally be completely eliminated.

Claims (1)

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass ausser der Wellenhöhe auch die Wellenlänge allmälig vermindert wird. EMI2.2 hin und zurück bewegt wird und mit einer Mehrzahl von Erhöhungen ausgerüstet ist, denen an dem andern Teil angeordnete Vertiefungen entsprechen, wobei die Erhöhungen und Vertiefungen von der Blecheintrittsstelle an gerechnet, allmählig an Höhe abnehmen. 2. The method according to claim 1, characterized in that in addition to the wave height and the Wavelength is gradually decreased. EMI2.2 is moved back and forth and is equipped with a plurality of elevations, which correspond to the depressions arranged on the other part, the elevations and depressions gradually decreasing in height, calculated from the sheet entry point. 4. Vorrichtung nach Anspruch 3 zur Ausführung des Verfahrens nach Anspruch 2, dadurch gekenn- zeichnet, dass die Erhöhungen bzw. Vertiefungen, von der Blecheintrittsstelle gerechnet, zunächst mit abnehmender Entfernung voneinander angeordnet sind. EMI2.3 4. Apparatus according to claim 3 for carrying out the method according to claim 2, characterized in that the elevations or depressions, calculated from the sheet metal entry point, are initially arranged with a decreasing distance from one another.
