  Blechhalterführung für Ziehpressen, Stanzen und dergleichen. 



   Bei den bisherigen mechanisch bewegten Blechhaltern für Ziehpressen, Stanzen und dergl., welche durch Einwirkung eienr unrunden Scheibe, eines Excenters oder   ders !. au   eine am   Blechhalter   befestigte Druckrolle bewegt werden, gelangen infolge dieser Einwirkung horizontale Kräfte in den Blechhalter, so dass die an dem oberen Theile der Blechhalterführung sitzenden Lagertheile der Druckrolle seitlichen Beanspruchungen ausgesetzt waren. welche nicht nur zum Bruche dieser Theile führten, sondern auch die Prismen leisten lockerten. Infolgedessen wurde die Blechhalterführung lose, und ein   Gratschneiden war     unvermeidlich,   besonders, wenn jene seitlichen Beanspruchungen in der   äussersten   Stellung der Blechhalterführung auftraten.

   Man nahm diese Nachtheile des Antriebes bisher in den Kauf, ohne sich über die Ursachen klar zu werden, welchen die   genannten Übelstände zu-   zuschreibenwaren. 



   Diese Nachtheile sollen durch den Gegenstand der vorliegenden Erfindung beseitigt 
 EMI1.1 
 Hebel befestigt, dessen   schwingendes   Ende mit dem Blechhalter   durch   gelenkige Zwischenglieder verbunden ist, welche sonst auch zwischen Druckrolle und   Blechhalter   angeordnet worden.   Vermöge dieser   Anordnung wird der Mittelpunkt der Druckrollen in Richtung der Achse des Blechhalters angenähert gerade geführt, so dass die Zv ischenglicder, u. zw. nur   wiihrend   des Leerganges des Blechhalters, eine praktisch nicht in Betracht   kommende   
 EMI1.2 
 führende Kraft durch die Achse der Blechhalterführung geht und nicht in   Seitenkräfte   zerlegt wird.

   Es entfallen also die seitlichen Kräfte, welche die Lagerstellen der Druckrollen und die Prismen der Blechhalterführung beanspruchen. 
 EMI1.3 
 den Zwischenstellungen vorkommt, bei welchen eine Kraft auf das Werkstück nicht ausgeübt wird.

  Sheet metal holder guide for drawing presses, punching and the like.



   In the previous mechanically moved sheet metal holders for drawing presses, punching and the like, which by the action of a non-circular disc, an eccentric or the like! If a pressure roller attached to the blank holder is moved, as a result of this action horizontal forces enter the blank holder, so that the bearing parts of the pressure roller seated on the upper part of the blank holder guide were exposed to lateral loads. which not only led to the fracture of these parts, but also loosened the prisms. As a result, the blank holder guide became loose and burr cutting was inevitable, especially if those side loads were in the extreme position of the blank holder guide.

   So far these disadvantages of the impulse have been accepted without being clear about the causes to which the abuses mentioned were to be ascribed.



   These disadvantages are intended to be eliminated by the subject matter of the present invention
 EMI1.1
 Fastened lever, the swinging end of which is connected to the blank holder by articulated intermediate links, which were otherwise arranged between the pressure roller and the blank holder. By virtue of this arrangement, the center of the pressure rollers is guided approximately straight in the direction of the axis of the blank holder, so that the Zv ischenglicder, u. or only while the blank holder is idle, which is practically out of the question
 EMI1.2
 leading force goes through the axis of the blank holder guide and is not broken down into lateral forces.

   The lateral forces that stress the bearing points of the pressure rollers and the prisms of the blank holder guide are therefore eliminated.
 EMI1.3
 occurs in the intermediate positions in which a force is not exerted on the workpiece.
