Nach dem neuen Verfahren wird ein in der erforderlichen Grundform beiderseits zur Mittellinie gleich gestaltetes Blechstück um die Mittellinie zusammengebogen und so der tragfähige Stift mit dem widerstandsfähigen Aufsehlagansatz hervorgebracht. Auf der Zeichnung ist dieses Verfahren in Fig. 1 bis 6 dargestellt.According to the new procedure, one in the required basic shape becomes the center line on both sides identically designed sheet metal piece bent together around the center line and thus the load-bearing one Bred pen with the resilient Aufsehlag approach. On the drawing is this method is illustrated in FIGS. 1-6.
Die Grundform (Fig. 1) zeigt den Zusammenhang des Lappens α eines einfachen Fenstereisens mit den zu ihrer Mittellinie y -y gleich gestalteten, ungetheilten Stift- und Aufschlagansatzhälften b. Diese Grundform ist in ebener Fläche (Fig. 2) ausgearbeitet.The basic shape (Fig. 1) shows the relationship between the tab α of a simple window bar and the undivided pin and sash halves b , which are identical to their center line y -y. This basic shape is worked out in a flat surface (Fig. 2).
Durch Pressen nach der Linie y-y werden die beiden Hälften b aufgebogen, so dafs sie eine offene Rinne bilden (Fig. 3 und 4), aus welcher durch Aneinanderrücken der oberen Kanten (Fig. 5 und 6) ein hohler Einschlagstift von rundem oder eiförmigem Querschnitt mit Aufschlagansatz entsteht. Die Herstellung solcher Stifte erfolgt in kaltem Zustande des Materials.By pressing along the line yy , the two halves b are bent open so that they form an open channel (Figs. 3 and 4), from which a hollow drive-in pin of round or egg-shaped cross-section is created by moving the upper edges together (Figs. 5 and 6) with a surcharge. The manufacture of such pencils takes place in the cold state of the material.
