Description

Matrize zum Stauchen von Bolzen. Zum Stauchen von Schrauben- und Nietbolzen werden Matrizen verwandt, die mit einem Loch in der Mitte versehen sind. Der Durchmesser der Matrize ist je nach der Stärke der zu schlagenden Bolzen 7o bis ioo mm, so daß der Stahlverbrauch ein, sehr großer ist. Die Erfindung besteht in einer Matrize, die mehrere Löcher trägt, so daß eine wesentliche Ersparnis an Stahl erzielt wird. Diese Matrize, die atü der Zeichnung in Seitenansicht und im Grundriß dargestellt ist, wird je nach Stärke der Bolzen mit drei oder vier Löchern gebohrt. Der Untersatz u ist entsprechend den Löchern der Matrize exzentrisch gebohrt, wodurch ermöglicht ist, die Matrize drei- oder viermal zu gebrauchen. Die Stahlersparnis beträgt gegenüber einer bisherigen Matrize mit einer Bohrung von 8o mm Durchmesser etwa 6o Prozent. Auch ist die Herstellung und spätere Nachbearbeitum_g eine weit billigere.Die for upsetting bolts. For upsetting screw and rivet bolts matrices with a hole in the middle are used. The diameter the die is 7o to 100 mm, depending on the strength of the bolts to be driven, so that the steel consumption is very large. The invention consists in a die, which carries several holes, so that a substantial saving in steel is achieved. This matrix, the atü of the drawing shown in side view and in plan is, depending on the strength of the bolt is drilled with three or four holes. The pedestal u is drilled eccentrically to match the holes in the die, which allows is to use the die three or four times. The steel savings are compared to a previous die with a bore of 8o mm diameter about 6o percent. The production and subsequent post-processing is also much cheaper.
