Description

Zum Umbiegen der Schenkelenden eines'Splintes dienen Splintzangen. Bei den bekannten zweischenkligen Splintzangen besitzt ein Backen eine Aussparung für den Splintkopf, während der andere Backen einen Keil trägt, der die beiden Schenkelenden auseinanderspreizt. Die 'Schenkelenden liegen aber an den zu sichernden Schrauben-oder Bundbolzen nicht satt an. Bei beweglichen Maschinen oder bei Fahrzeugen führt dies zum Klappern bzw. zum Ausschlagen der Splintbohrungen und der Splinte selbst. Damit steigt die Gefahr des Verlierens, so daß der Splint als 'Sicherungselement seinen eigentlichen Sinn verliert.Splint pliers are used to bend the leg ends of a split pin. In the known two-legged split-pin pliers, one jaw has a recess for the split pin head, while the other jaw carries a wedge that connects the two leg ends spreads apart. The 'leg ends are however on the screw or screw to be secured Collar bolts not fed up. This leads to moving machines or vehicles for rattling or knocking out the split pin holes and the split pins themselves increases the risk of losing, so that the cotter pin as' his securing element loses its real meaning.

Es galt, eine Zange zu entwickeln, die die beiden Schenkelenden völlig umbiegt. Erfindungsgemäß ist der die Schenkelenden des 'Splintes auseinanderspreizende Keil in seinen Zangenbacken verschiebbar geführt und kann durch einen Riegel ausgeklinkt werden, so daß bei einem weiteren Zusammendrücken der Zange der den Keil führende Zangenbacken selbst die Schenkelenden des'Splintes satt umbiegt. Die Zange zum Umbiegen von Splinten besteht in der Hauptsache aus den beiden Zangenschenkeln i und 2. Der Zangenschenkel 2 hat an seinem vorderen Ende eine Ausnehmung 3, in die der Splintkopf hineinpaßt. Der Zangenschenkel i hat, der Ausnehmung 3 gegenüberliegend, ein keilförmiges Teil 4, welches im gespreizten Zustand der Zange durch den Riegel s, der in die Nut 6 eingreift, gehalten wird. Der Keil kann somit seine Lage zunächst nicht verändern. Beim Zusammendrücken der Zange werden zunächst die Splintschenkel in die angedeutete Stellung auseinandergebogen. Beim weiteren Schließen der Zange haben sich die Zangen-Schenkel sö weit -geschlossen, daß der einstellbare Stift 7 den Hebel 8, an dem der Riegel 5 angelenkt ist, aus der Nut 6 herausgezogen hat. Der Keil 4 und die Feder 9 wirken zusammen jetzt nur noch wie ein Niederhalter in Ziehwerkzeugen. Die beiden Splintschenkel liegen an den Punkten z o des Zangenbackens an und werden beim weiteren Zusammendrücken satt umgebogen. Der Vorgang des Versplintens, der in einem Zuge vor sich gegangen ist, ist damit beendet. Beim Öffnen der Zange wird der Kraftschluß zwischen dem Stift 7 und dem Hebel 8 gelöst. Dann kommt die Feder 12 zur Wirkung. Sie erteilt dem Hebel 8 eine Drehung entgegengesetzt dem Uhrzeigersinn, wodurch der Riegel 5 in die Nut des durch die Feder 9 nach vorn geschobenen keilförmigen Teiles 4 einschnappt. Damit ist die Zange zum Wiederholen des Vorganges bereit.The task was to develop a pair of pliers that completely encompassed the two ends of the legs bends. According to the invention, the one that spreads the leg ends of the split pin apart Wedge slidably guided in its jaws and can be disengaged with a latch so that if the pliers are pressed together further, the one leading to the wedge Pliers jaws even bend the leg ends of the splint. The pliers for bending of split pins consists mainly of the two pliers legs i and 2. The Pliers leg 2 has a recess 3 at its front end, into which the cotter pin head fits in. The pliers leg i, opposite the recess 3, is wedge-shaped Part 4, which in the spread state of the pliers by the latch s, which is in the Groove 6 engages, is held. The wedge can therefore initially not change its position. When you squeeze the pliers, the split pin legs are first pushed into the indicated Position bent apart. When you close the pliers further, the pliers legs have each other so far-closed that the adjustable pin 7 the lever 8 on which the bolt 5 is hinged, has pulled out of the groove 6. The wedge 4 and the spring 9 act together now just like a hold-down device in drawing tools. The two split pin legs lie at the points z o of the jaws of the pliers and are pressed together further bent over. The process of splinting that happened in one go is ended. When you open the pliers, the frictional connection between the Pin 7 and the lever 8 released. Then the spring 12 comes into effect. You granted the lever 8 a counterclockwise rotation, whereby the bolt 5 snaps into the groove of the wedge-shaped part 4 pushed forward by the tongue 9. The pliers are now ready to repeat the process.
