Patentirt im Deutschen Reiche vom 24. Januar 1890 ab.Patented in the German Empire on January 24th, 1890.
Die Vorrichtung dient für den Maschinenbetrieb von Schraubenpressen.The device is used for the machine operation of screw presses.
R ist in allen Figuren das Handrad der Presse, α ein Excenter, welches direct von der Wellenleitung oder von einem Vorgelege seine Bewegung erhält. Auf der Stange dieses Excenters sitzt in Fig. 1 zwischen zwei Federn / und/1, welche durch die Stellringe ss stärker oder schwächer gespannt werden können, eine lose Hülse c, welche mit dem Hebel h verbunden ist und diesen hin- und herbewegt. Der Hebel h trägt eine excentrische oder gewöhnliche Schaltklinke ft, die bei jedem Hub das Rad R ein Stück vorwärts dreht. Dessen Rückbewegung verhindert die Sperrklinke ft1. In all figures, R is the handwheel of the press, α an eccentric, which gets its movement directly from the shaft line or from an intermediate gear. On the rod of this eccentric sits in Fig. 1 between two springs / and / 1 , which can be tightened more or less by the adjusting rings ss , a loose sleeve c, which is connected to the lever h and moves it back and forth. The lever h carries an eccentric or ordinary pawl ft which turns the wheel R a little forward with each stroke. The pawl ft 1 prevents its return movement.
So lange der Federdruck auf die Hülse c gröfser ist als der entsprechende Druck der Prefsplatte auf das Prefsgut, folgen die Hülse c und die Federn/ und f1 den Bewegungen der Excenterstange und rücken das Rad R mittelst des Hebels h vorwärts. Erreicht dagegen der Druck der Prefsplatte auf das Prefsgut und hierdurch der Widerstand des Rades R gegen den Hebel h eine gröfsere Stärke, als die Feder/ besitzt, so wird sich diese bei den Bewegungen der Excenterstange nur abwechselnd zusammendrücken, ohne dafs die Hülse c mit dem Hebel h sich bewegt, bis das Prefsgut dem Drucke nachgegeben hat und die Federkraft wieder überwiegt.As long as the spring pressure on the sleeve c is greater than the corresponding pressure of the Prefsplatte on the material to be pressed, the sleeve c and the springs / and f 1 follow the movements of the eccentric rod and move the wheel R forward by means of the lever h. If, on the other hand, the pressure of the pre-filling plate on the material to be pressed, and thereby the resistance of the wheel R against the lever h, reaches a greater strength than the spring / has, it will only compress alternately during the movements of the eccentric rod, without the sleeve c and the Lever h moves until the material to be pressed has yielded to the pressure and the spring force prevails again.
Auf diese Weise wirkt immer derjenige höchste Druck auf das Prefsgut, welcher der Stärke der Feder/ entspricht, und dieser Druck kann durch stärkere Spannung der Feder / mittelst des Stellringes s beliebig erhöht oder durch Nachlassen oder Anbringen einer schwächeren Feder beliebig verringert werden.In this way, the highest pressure always acts on the material to be pressed, which corresponds to the strength of the spring /, and this pressure can be increased as desired by stronger tension of the spring / by means of the adjusting ring s or decreased as desired by releasing or attaching a weaker spring.
Letzteres ist besonders bei sehr weichen Prefskörpern zum Schütze der Prefstücher von Bedeutung. The latter is particularly important in the case of very soft prefabricated bodies to protect the prefabricated cloths.
Die Feder/1 ist schwächer als die Feder/ und hat den Zweck, die Hülse c mit dem Hebel h zurückzudrücken.The spring / 1 is weaker than the spring / and has the purpose of pushing back the sleeve c with the lever h.
Die Federn/ und fl, sowie die lose Hülse c lassen sich auch dadurch ersetzen, dafs die Excenterstange mit Blattfedern n>, Fig. 2, und diese mit dem Hebel h verbunden werden, oder dafs der letztere sich selber zu einer Blattfeder d, Fig. 3, verlängert, welche durch die Excenterstange hin- und herbewegt wird. Die Stärke der Blattfedern w und d regulirt auch hier selbstthätig den Druck.The springs / and f l , as well as the loose sleeve c , can also be replaced by connecting the eccentric rod with leaf springs n>, Fig. 2, and these with the lever h , or that the latter turns itself into a leaf spring d, Fig. 3, extended, which is moved back and forth by the eccentric rod. Here, too, the strength of the leaf springs w and d automatically regulates the pressure.
