 geschmiedete Zapfen desselben. Fig. 8 ist in beiden Ansichten die unter dem Werkzeuge I vorgepresste und gelochte Schale desselben. Ebenso zeigt Fig. 9 bei 5 die Dülle eines Schaufelschützen. 



  51 ist der vorgeschmiedete Zapfen derselben. Ebenso wie bei der Ohrbildung erfolgt auch bei der Düllenbildung, wie Fig. 10 zeigt, durch Vorpressen des Zapfens zwischen den Gesenken   N 1   und 01 die Bildung einer gelochten    Schale : die zwisc11en   einem Werkzeuge 11, genau so wie bei allen Ohrgattungen, durch einen Dorn in einem Gesenk zur vollen Länge geöffnet und gleichzeitig der entstandene Grat abgeschert wird. 



   Durch das beschriebene Verfahren werden Risse in den   Ohrrändefn   vermieden und die Ohrwände durch vollkommenes Ausfüllen der Gesenkformen fehlerfrei hergestellt, so dass man durch zwi Pressdrücke aus dem vorgeschmiedeten Zapfen ein genaues Ohr bzw. Dülle von   gewünschter   bestimmter Form, Grösse und Wandstärke erhält. 
 EMI2.2 
 
1. Verfahren zur Herstellung von Hauen und Hackenöhre sowie Schaufeldüllen und ähnlichen   Stiellöchorn,   dadurch gekennzeichnet, dass bei der durch Pressen erfolgenden Vorbildung des für das Ohr oder die Dülle vorgeschmiedeten Zapfens zu einer Schale ein Lochen desselben und beim nachfolgenden Kalibrieren ein Abscheren des Grates von den Ohr-oder Düllenkanten erfolgt.

 EMI2.1
 forged tenons of the same. Fig. 8 is in both views the pre-pressed and perforated shell of the tool I under the same. Likewise, FIG. 9 shows at 5 the nozzle of a blade gate.



  51 is the forged tenon of the same. As with the ear formation, with the socket formation, as shown in FIG. 10, a perforated shell is formed by pre-pressing the pin between the dies N 1 and 01: the one between a tool 11, just as with all types of ears, by a mandrel opened to the full length in a die and at the same time the resulting burr is sheared off.



   The method described avoids cracks in the ear rims and the ear walls are made flawless by completely filling the die, so that an exact ear or socket of the desired specific shape, size and wall thickness is obtained by pressing between the pre-forged pins.
 EMI2.2
 
1. A method for the production of picks and hoe ears and shovel sockets and similar handle holes, characterized in that in the pre-forging of the pin pre-forged for the ear or socket into a shell, a hole is made and the burr is sheared off during the subsequent calibration Ear or socket edges are made.
