Abstract

Bei einer Vorrichtung zum Entfernen von Ausbrechteilen, vor allem von Abfallstücken, aus einem Zuschnitte od. dgl. Flächenstücke enthaltenden Werkstoffbogen ist einem Ausbrechwerkzeug eine in seiner Bewegungsrichtung bewegbare Widerlagereinrichtung zugeordnet, die in einen Durchbruch ragt sowie in Ruhelage das im Werkstoffbogen befindliche Ausbrechteil oder Abfallstück etwa parallel untergreift und beim Bewegen des Abfallstückes durch das Ausbrechwerkzeug in seiner Lage veränderlich -- insbesondere beim Absenken des Abfallstückes in einen Neigungswinkel zum Werkstoffbogen überführbar -- ausgebildet ist. Als Ausbrechwerkzeug dient ein Druckstift mit gerundeten freien Enden oder ein Gabelorgan mit zumindest einem fingerartigen Gabelzinken. Diese Widerlagereinrichtung wird von einem Widerlagerwerkzeug gebildet, das mit der Ausbrechfläche oder Matrize im Randbereich des Durchbruchs formschlüssig starr verbunden sowie mit einer gegenüber dieser Verbindungspaarung neigbaren Auflage- oder Widerlagerfläche ausgestattet ist.

Figure 00000001
In the case of a device for removing stripped parts, especially waste pieces, from a sheet of material containing blanks or the like, a stripping tool is assigned an abutment device which is movable in its direction of movement, which protrudes into an opening and, in the rest position, the stripped part or waste piece located in the material sheet, for example engages in parallel and is variable in its position when the waste piece is moved by the stripping tool - in particular when the waste piece is lowered into an angle of inclination to the sheet of material - can be converted. A push pin with rounded free ends or a fork member with at least one finger-like fork prong serves as the stripping tool. This abutment device is formed by an abutment tool which is rigidly connected to the break-out surface or die in the edge region of the opening and is equipped with a support or abutment surface which can be inclined with respect to this connection pairing.
