Formen am Formrade.Shapes on the form wheel.

Der Erfindungsgegenstand soll bei Matrizensetz- und Zeilengießmaschinen mit mehreren verschiedenen Formen am Formrade das schnelle und sichere Abstellen der Maschine nicht nur dann bewirken, wenn Matrizen einer bestimmten Art sich nicht in der gehörigen Lage vor der zugehörigen Form befinden, sondern auch dann, wenn die Weite der Form und die Kegelstärke der benutztenThe subject of the invention is intended for die setting and line casting machines with several various shapes on the forming wheel enable the machine to be switched off quickly and safely not only have an effect when matrices of a certain type are not in the proper one Position in front of the associated shape, but also when the width of the shape and the cone thickness of the used

ίο Matrizen nicht übereinstimmen. Er stellt eine Einrichtung dar, bei welcher für jede Form eine Vorrichtung vorgesehen ist, die entsprechend der Abmessung der zugehörigen Form während ihrer Drehung mit dem Formrade eine Schiene, die geradlinig in einer undrehbaren Führung gleitet und ein Loch besitzt, welches einen Vorsprung an der Ausrückstange aufnehmen kann, entgegen der Wirkung einer Feder in verschiedene Stellungen bewegt, so daß nur, wenn das Loch in der geradlinig geführten Schiene mit diesem Vorsprunge übereinstimmt, die Maschine weiter arbeiten kann.ίο matrices do not match. Created a device in which a device is provided for each shape, the according to the dimension of the associated shape as it rotates with the shaping wheel a rail that slides in a straight line in a non-rotating guide and has a hole, which can accommodate a projection on the release rod, against the effect a spring moved in different positions, so that only when the hole in the linearly guided rail with this protrusion matches, the machine can continue to work.

Die Zeichnung zeigt eine Ausführungsform des Erfindungsgegenstandes, und zwar in:The drawing shows an embodiment of the subject matter of the invention, namely in:

Fig. ι einen senkrechten Schnitt durch das Formrad, den Gießschlitten und die Kupplungskontrollvorrichtungen, Fig. Ι a vertical section through the molding wheel, the casting slide and the coupling control devices,

Fig. 2 eine Ansicht des Formrades mit zwei Formen und dem Kupplungskontrollschlitten, Fig. 3 einen senkrechten Schnitt durch Teile der Fig. 1 in der Ausstoß st ellung der Gießform. Fig. 2 is a view of the form wheel with two forms and the clutch control slide, Fig. 3 is a vertical section through parts of FIG. 1 in the ejection st osition of the mold.

Die Fig. 4 und 5 sind wagerechte Schnitte nach den Linien 8-8 und 9-9 der Fig. 3.FIGS. 4 and 5 are horizontal sections along lines 8-8 and 9-9 of FIG. 3.

A ist ein Teil des Maschinengestell, in welchem der Gießschlitten N auf und ab beweglich ist. Der Gießschlitten nimmt die an den oberen und unteren Ecken mit vorspringenden Ohren versehenen Matrizen Y auf, nachdem sie zur Zeile unter Einschaltung von Keilspatien zusammengesetzt sind. Das in senkrechter Ebene drehbare Formrad O trägt die beiden einander diametral gegenüberliegenden Formen 0 und o\ Dieses Formrad dreht sich um einen Zapfen des Formradschlittens o⁴. Um die Maschine anzuhalten, wenn der Gießschlitten nicht völlig bis in die Gieß linie gesenkt ist, ist eine Schiene α¹² vorhanden, welche die Hauptantriebskupplung der Maschine kontrolliert und mit einem Hebel α²² verbunden ist. Dieser befindet sich im Maschinengestell in solcher Lage, daß eine Schiene a²³ auf ihn wirken kann, die im wesentlichen senkrecht, an ihrem unteren Ende aber auch wagerecht beweglich ist. Diese Schiene α²³ ist mit dem oberen Ende im Hauptgestell geführt und wird beständig durch eine Feder β²⁴ aufwärts gedrängt. Senkt sich der Gießschlitten N mit der Matrizenzeile, so wirkt er auf das obere Ende der Schiene α²³ und schiebt diese abwärts. Befindet sich der Gießschlitten und die Matrizenzeile richtig in der Gießstellung, so berührt kein Teil des Formrades oder der Vorrichtung an ihm den Vorsprung α²⁶. Infolgedessen bleibt die A is a part of the machine frame in which the casting slide N can be moved up and down. The casting slide picks up the matrices Y , which are provided with protruding ears at the upper and lower corners, after they have been assembled into a row with the inclusion of wedge spaces. The shaping wheel O , which can be rotated in a vertical plane, carries the two diametrically opposed shapes 0 and o \ This shaping wheel rotates around a pin of the shaping wheel slide o ⁴ . In order to stop the machine when the casting slide is not completely lowered into the casting line, a rail α ^{12 is} provided, which controls the main drive clutch of the machine and is connected to a lever α ²² . This is in the machine frame in such a position that a rail a ²³ can act on it, which is essentially vertical, but also horizontally movable at its lower end. This rail α ²³ is guided with the upper end in the main frame and is constantly urged upwards ^{by a spring β 24.} If the casting slide N with the die line descends, it acts on the upper end of the rail α ²³ and pushes it downwards. If the casting slide and the die line are correctly in the casting position, no part of the forming wheel or the device touches the projection α ^{26 on it} . As a result, the

Claims

Rail a ²³ at rest and ineffective on the main coupling, so that the latter drives the machine. If, on the other hand, the casting slide with the die line has not properly descended into the casting position, the projection α ^{26 is influenced} by the molding wheel moved against the mold in such a way that it and the rail a ^{23 are moved} forward so that the latter is moved by the lever a ^2%

ίο and the rail α ¹² disengage the main coupling and the machine will turn off. So far the facility is known.

The coupling ^{control rail α 23} can be depressed by direct contact with the copy of the casting slide. However, it is more advantageous to let a set screw or an adjustable stop in the head of the casting slide act on them in a known manner, as the drawing shows.

So that the arm a ^{26 is} only not actuated when the alignment ^{shoulder o 2} is at the correct height opposite the lower ears of the dies, a vertically guided plate / is arranged on the end face of the non-rotatable pin carrying the forming wheel is constantly pulled upwards by a spring /. The lower end of this plate contains the hole j ¹ which receives the end of the projection α ²⁶ when the coupling is to remain in effect. On the upper end of the plate / acts (Fig. 1 to 3) a projection or projection K on the underside of the mold or its holder. This projection or approach K extends downwards to different degrees in the various forms. If now a certain shape is brought into the casting position during the rotation of the molding wheel, its approach or projection K will move the plate / downwards until its hole is directly opposite the arm a ²⁶ , provided that the casting slide correctly enters the die line The casting line has been lowered and the projection α ^{26 has moved} correspondingly far downwards. If the casting carriage has not moved the line correctly or if a form that is not suitable for the line in question is in the casting position, so that the plate / has not been pushed down into the correct position, the forming wheel will move forward against the line of die swing arm a ²⁶ forward and cause rail a ²³ to disengage the main clutch through the intermediate linkage.

The projections or lugs K can be arranged and in the form of blocks not only directly on the mold or the mold holder, but also in some way on the molding wheel. be attached. It is only necessary that they join in the rotation of the forming wheel and act on the slide or the plate / in such a way that, when a mold is brought into its working position, the slide or the plate / experiences the appropriate and suitable setting.

The device shown allows a double control of the main drive coupling, namely first of the height adjustment of the casting slide and its effect on the rail ²³ dependent and second that which is dependent on the effect of the projection or projection K on the shape that is currently in the casting position is. If the dies are not in the correct position in the casting line or if a mold that does not correspond to the dies in question is in the casting position, the machine is switched off.

Ρλτεντ claims:

Shelf device for die setting and line casting machines with several different shapes on the molding wheel, each of which carries a single-setting stop corresponding to its dimensions, characterized in that the stops (K), according to their different dimensions, serve to move a rail (J) during their rotation. , which slides in a straight line in a guide independent of the rotation of the form wheel and has a hole (j ¹ ) which receives the projection (α ^2β ) on the release rod (a ²³ ) to move against the action of a spring in different positions, so that the machine can only continue to work when the hole (j ¹ ) coincides with the projection (a ²⁶ ) .
