Description
Die Erfindung betrifft solche von Hand betriebenen Fofmmaschinen, bei welchen die Pressung des Sandes in zwei oder mehr Stufen vermittels Handhebel bewirkt wird, so daß die Kraft des Arbeiters für eine geeignete Pressung in mehrere nahezu gleiche Teile geteilt wird, wobei die Hubabstufungen verschiedene Länge haben, und zwar entspricht der ersten Pressung, welcher der geringere Widerstand entgegensteht, die größte Hublänge, während der zweiten Pressung eine kürzere Hublänge entspricht, die aber kräftiger wirkt.The invention relates to such hand-operated film machines, in which the The sand is pressed in two or more stages by means of hand levers, so that the strength of the worker for a suitable pressing in several nearly equal Parts is divided, the stroke gradations have different lengths, and that corresponds the first pressing, which is opposed by the lower resistance, the greatest stroke length, during the second pressing one corresponds to a shorter stroke length, but it has a stronger effect.
Gegenüber bekannten Formmaschinen dieser Art ist bei der den Gegenstand vorliegender Erfindung bildenden Handformmaschine das eine Preßorgan auf dem Querbügel der Maschine, das andere unten im Gestell der Maschine angeordnet.Compared to known molding machines of this type, the subject is present in the Invention forming hand molding machine that has a pressing member on the cross bar of the machine, the other arranged at the bottom in the frame of the machine.
Die Erfindung ist in der beigegebenen Zeichnung beispielsweise veranschaulicht, und zwar zeigt:The invention is illustrated in the accompanying drawing, for example shows:
Fig. ι die Ansicht einer Formmaschine mit doppelter Pressung,Fig. Ι the view of a molding machine with double pressing,
as Fig. 2 eine Seitenansicht der Maschine teilweise im Schnitt.As Fig. 2 is a partial side view of the machine on average.
Das Maschinengestell ι trägt in zwei seitlichen Lagern 2 eine wagerechte Welle 3, auf welcher Führungen 4 lose drehbar sind. In den Führungen 4 sind senkrechte Stangen 5 verschiebbar. Letztere besitzen an ihrem oberen Ende ein Schraubengewinde und tragen je zwei Schraubenmuttern 6, zwischen denen die beiden äußeren Hülsen des Querbügels 7 festgeklemmt werden. Der Querbügel 7 besitzt ebenfalls eine mittlere Hülse 8 zur Führung der Säule 9, an deren unterem Ende die Druckplatte 10 befestigt ist. Mit der Säule 9 sind mittels einer Welle 11 Lenkstangen 12 verbunden, welche durch auf einer Welle 13 befestigte Hebel 14 beeinflußt werden, wobei die Welle 13 in dem Querbügel 7 geführt und durch einen Handhebel 15 gedreht werden kann.The machine frame ι carries a horizontal shaft 3 in two lateral bearings 2 which guides 4 are loosely rotatable. In the guides 4 are vertical rods 5 movable. The latter have a screw thread at their upper end and carry two nuts 6 each, between which the two outer sleeves of the cross bracket 7 are clamped. The transverse bracket 7 also has a central sleeve 8 for guiding the column 9, at the lower one The end of the pressure plate 10 is attached. With the column 9 are 11 handlebars by means of a shaft 12 connected, which are influenced by lever 14 mounted on a shaft 13, the shaft 13 being guided in the transverse bracket 7 and rotated by a hand lever 15 can be.
Die beiden Stangen 5 sind in den Hülsen 4 auf und ab bewegbar und tragen je einen festgekeilten Ring 16. Die Ringe 16 besitzen je einen Zapfen Vj, an welchem eine durch ein auf der Welle 3 sitzendes Exzenter 18 betätigte Lenkstange 19 angreift. Die Welle 3 wird durch einen Handhebel 20 betätigt.The two rods 5 can be moved up and down in the sleeves 4 and each carry a tightly wedged ring 16. The rings 16 each have a pin Vj on which a steering rod 19 actuated by an eccentric 18 seated on the shaft 3 engages. The shaft 3 is actuated by a hand lever 20.
Zur Pressung des Formkastens wird der während der Füllung nach hinten zurückgestoßene Querbügel 7 der Maschine über den .Formkasten gebracht, indem er mittels der Stangen 5 um die Welle 3 herumgedreht wird. Hierauf wird der Handhebel 15 herunterbewegt, so daß mittels der Hebel 14 und Lenkstangen 12 die Preßplatte 10 gesenkt und die Form ein erstes Mal zusammengepreßt wird. Beim darauffolgenden Herumdrehen des Hebels 20 werden dann die Exzenter 18 gedreht, wodurch die Lenkstangen 19 sowie die beiden Zugstangen 5 abwärts bewegt werden. Die Druckplatte wird infolgedessen um eine der Hublänge der Exzenter entsprechende Höhe abwärts bewegt, so daß die durch die Gelenke 14,12 fortwährend in gleichem AbstandTo press the molding box, the box that is pushed back during filling is pushed back Cross bracket 7 of the machine brought over the .Formkasten by using the Rods 5 is rotated around the shaft 3. The hand lever 15 is then moved down, so that by means of the lever 14 and handlebars 12, the pressure plate 10 is lowered and the Form is pressed together a first time. When the lever is then turned around 20 the eccentrics 18 are then rotated, whereby the handlebars 19 as well as the two Tie rods 5 are moved downwards. The printing plate is consequently one of the Stroke length of the eccentric corresponding height moves downwards, so that the through the joints 14.12 continuously at the same distance
von dem Querbügel gehaltene Preßplatte io von neuem auf die Form gepreßt wird.The press plate held by the transverse bracket is pressed onto the mold again.
