Description

Locher mit senkrechter Stempelführung und einem Fangstift für regelrechten Vorschubabstand für Schuhkappen. Die Erfindung bezieht sieh auf als Ersatz für Lochzangen dienende Locher für Schuhkappen. Locher mit senkrechter Stempelführung und einem Fangstift für regelrechten Vorschubabstand sind bekannt. Die Erfindung bezweckt, beim Vorschub des zu lochenden Werkstückes. eine zuverlässige Wirkung herbeizuführen, außerdem eine Änderung des Vorschubabstandes zu ermöglichen. Dies wird dadurch erreicht, daß der Fangstift in einem einstellbaren Tragstück federnd angeordnet ist, so daß er durch den Druck der Feder bei vier Vorschubbewegung gegen das Werkstück gepreßt wird und in das soeben hergestellte Loch einspringt, wodurch das Werkstück augenblicklich für die nächste Lochung bis zur erneuten Vorschubbewegung festgestellt wird. Hierdurch ergeben sich auch für das Lochen von Hand genaue und je nach Bedarf zu ändernde Abstände der Kappenlochungen, ohne daß es weiterer mechanisch beeinflußter und zwangläufig bewegter Mittel bedarf.Hole punch with vertical punch guide and a catch pin for regular ones Feed distance for shoe caps. The invention relates to as a replacement for punch pliers serving holes for shoe caps. Hole punch with vertical punch guide and one Catch pins for regular feed distance are known. The invention aims at the advance of the workpiece to be punched. to bring about a reliable effect, also to enable a change in the feed distance. This is achieved by that the catch pin is resiliently arranged in an adjustable support piece, so that it is pressed against the workpiece by the pressure of the spring during four feed movements and jumps into the hole just made, causing the workpiece to be instantly for the next perforation is determined until the new feed movement. Through this also result for punching by hand which are precise and can be changed as required Distances between the cap perforations without further mechanically influenced and inevitable moving resources are required.

Die Zeichnung zeigt einen Handlocher für Schuhkappen, welcher mit dem Fangstift gemäß der Erfindung ausgerüstet ist, in Fig. z in Seiten-, in Fig. a in Vorderansicht. Fig. 3 veranschaulicht die Einrichtung teils im wagerechten Schnitt nach Linie C-D der Fig. r, teils in Oberansicht. Fig. 4 stellt einen Teil einer gelochten Schuhkappe dar. Die Lochstempel i zur Herstellung der in Fig. 4 veranschaulichten Lochungen sind in einem Futter g des in einem Bock a, b, c senkrecht geführten Stempelschaftes e untergebracht, der entgegen der Wirkung der sich gegen den Anschlag p, g anlegenden Feder o, n durch Druck auf Knopf f nach abwärts bewegt wird und hierbei das über die kupferne, um Schraube L drehbare Unterlegscheibe k bewegte Werkstück mit der Lochreihe gemäß-Fig:4 versieht. Um letztere in gleichmäßigem Abstande vom Rande der Kappe auszuführen, wird -der Rand gegen die Führungsleiste r gedrückt, die mittels der sich im Schlitz t führenden Schraube s innerhalb gewisser Grenzen verstellt werden. kann, während der Abstand der Löcher der Lochreihe (Fig. 4) untereinander durch einen Fangstift x bestimmt wird.The drawing shows a hand punch for shoe caps, which is equipped with the catch pin according to the invention, in Fig. Z in side, in Fig. A in front view. FIG. 3 illustrates the device partly in a horizontal section along the line CD in FIG. R, partly in a top view. Fig. 4 represents a part of a perforated shoe cap is the punch i for the preparation of the illustrated in Fig. 4 holes are. In a chuck g of a plate a, b, c vertically guided punch shaft e housed, which against the action of the mutually the spring o, n applying the stop p, g is moved downwards by pressing button f and hereby provides the workpiece, which is moved over the copper washer k rotatable about screw L , with the row of holes according to FIG. 4. In order to carry out the latter at a uniform distance from the edge of the cap, the edge is pressed against the guide strip r, which can be adjusted within certain limits by means of the screw s leading in the slot t. can, while the distance between the holes of the row of holes (Fig. 4) is determined by a catch pin x.

Nach vorliegender Erfindung ist dieser Fangstift x in zwei einander deckenden Bohrungen eines aus zwei wagerechten Schenkeln w, w' bestehenden Tragstückes untergebracht, dessen plattenförmiger Fuß an der Gesfiellplatte a mittels Schraube v, um :deren Bolzen das Tragstück und dessen Schenkel w, w' in wagerechter Ebene gedreht werden können, befestigt ist. Durch Drehung des Tragstückes w, w' um den Bolzen v können die Abstände des Fangstiftes x von den Lochstempeln i und somit der Löcher der Lochreihe (Fig.4) voneinander nach Bedarf geändert werden. Gegen den unteren Schenkel w' des Tragstückes legt sich der Fangstift mittels eines Bundes an, gegen welchen eine um den Stift gewundene Schraubenfeder drückt, die sich mit ihrem anderen Ende gegen den oberen Schenkel w des Tragstückes anlegt.According to the present invention, this catch pin x is housed in two overlapping bores of a support piece consisting of two horizontal legs w, w ' , the plate-shaped foot of which is attached to the Gesfiellplatte a by means of screw v, around: whose bolts the support piece and its legs w, w' in horizontal plane can be rotated, is attached. By rotating the support piece w, w 'around the bolt v, the distances between the pilot pin x and the punches i and thus the holes in the row of holes (FIG. 4) can be changed from one another as required. The catch pin rests against the lower leg w 'of the support piece by means of a collar, against which a helical spring, wound around the pin, presses, the other end of which rests against the upper leg w of the support piece.

Der federnd angeordnete Fangstift drückt unter Wirkung der Feder mit seinem unteren Ende gegen das an der Leiste r auf der Unterlage k bewegte Werkstück und springt unter dem Federdruck während der Vorschubbewegung in das soeben gestanzte letzte Loch der Lochreihe ein, wodurch das _ Werkstück für die nächste Lochung bis zur erneuten Vorschubbewegung festgestellt wird und die Abstände im Verlauf des Arbeitsvorganges genau festgelegt werden.The spring-mounted catch pin also presses under the action of the spring its lower end against the workpiece moved on the bar r on the base k and jumps under the spring pressure during the feed movement into the just punched last hole in the row of holes, which means that the workpiece is ready for the next hole up for the renewed feed movement is determined and the distances in the course of the Work process can be precisely defined.
