Blechscheere mit hydraulischem Antrieb.Metal shears with hydraulic drive.
Patentirt im Deutschen Reiche vom 22. Januar 1895 ab.Patented in the German Empire on January 22nd, 1895.
Da bei Scheeren bei Beginn des Eingriffs der Schneiden stets ein einseitiger, dann ein nach der anderen Seite wandernder Druck entsteht, liefssich bisher der Niedertrieb von Scheeren mit breiten Messern durch hydraulischen Druck nicht ermöglichen. Selbst wenn man das bewegliche Scheerenmesser durch zwei hydraulische Cylinder und eine Leitung bedienen wollte, so würden doch Unzuträ'glichkeiten entstehen, indem ein Vorauseilen der noch nicht arbeitenden Messerseite eintreten müfste. In jedem Falle ergeben sich eine sehr unangenehme Beanspruchung der Führungen und sonstige Unbequemlichkeiten.Since with scissors at the beginning of the engagement the cutting edge is always one-sided, then one after the On the other hand, there is wandering pressure, so far the driving down of shears has been running with broads Do not allow knives due to hydraulic pressure. Even if you have the movable Wanted to operate scissors knife by two hydraulic cylinders and a line, so but inconveniences would arise by hurrying ahead of those who are not yet working Would have to enter the knife side. In any case, the result is a very uncomfortable one Use of the guides and other inconveniences.
Durch die vorliegende Erfindung wird nun die Aufgabe gelöst, Blechscheeren, selbst solche von erheblicher Breite, durch hydraulische Kraft zu bewegen, ohne dafs gefährliche einseitige Inanspruchnahmen entstehen.The present invention now solves the problem of sheet metal shears, even such of considerable breadth, to be moved by hydraulic force, without dangerously one-sided Claims arise.
Dies wird durch Anwendung nur eines hydraulischen Cylinders erreicht, der mit seiner Achse nicht in der Richtung des Druckes, sondern senkrecht zu dieser liegt. Der Kolben wirkt daher nicht direct, sondern unter Zwischenschaltung von keilartig wirkenden Druckflächen, wie aus der Zeichnung sich ergiebt.This is achieved by using only one hydraulic cylinder, which with its Axis is not in the direction of the pressure, but perpendicular to it. The piston therefore does not act directly, but with the interposition of wedge-like acting pressure surfaces, as is evident from the drawing.
Der hydraulische Cylinder α ist in der Mitte des Scheerengestelles an der oberen Traverse waagrecht befestigt. Durch den Kolben b geht die gleichfalls waagrechte Kolbenstange c hindurch. Diese trägt an beiden Enden die Köpfe d und d1, welche vier Rollen e tragen. Die unteren dieser Rollen laufen auf schräg ansteigenden Bahnen am Haupte des oberen Messerträgers, während die oberen Rollen e gegen eine waagrechte Führungsbahn sich stützen. Tritt bei f Druckwasser hinter den Kolben, so bewegt sich dieser mit der Kolbenstange c in der Richtung der in Fig. 1 angegebenen Pfeile, wobei die Rollen e den Scheerenmesserträger g genau parallel zu sich selbst an den Führungen niederbewegen, so dafs der Schnitt erfolgt.The hydraulic cylinder α is fastened horizontally in the middle of the scissors frame on the upper cross member. The piston rod c , which is also horizontal, passes through the piston b. This carries the heads d and d 1 at both ends, which carry four rollers e. The lower of these rollers run on sloping tracks on the head of the upper knife carrier, while the upper rollers e are supported against a horizontal guideway. Occurs at f water pressure behind the pistons, so it moves with the piston rod c in the direction indicated in Fig. 1, arrows, the rollers e the razor carrier g exactly parallel to itself down move on the guides, the average DAF occurs.
Wird dann der Druck bei f abgestellt, so dafs das Druckwasser ablaufen kann, so kann der Kolben irgendwie mechanisch zurückbewegt werden. Letzteres geschieht zweckmäfsig in der Weise, dafs der Kolben, wie dargestellt, als Differentialkolben wirkt; indem er dabei durch die Druckleitung h auf der für den Rückgang wirkenden Seite stets unter Druck steht, wird er zurückbewegt, sobald der Druck auf der anderen Seite aufgehoben wird.If the pressure is then turned off at f so that the pressurized water can run off, the piston can somehow be moved back mechanically. The latter is expediently done in such a way that the piston, as shown, acts as a differential piston; in that it is always under pressure through the pressure line h on the side acting for the decline, it is moved back as soon as the pressure on the other side is released.
Während des Rückganges des Kolbens wird auch der obere Messerträger wieder aufwärts bewegt, was etwa durch den kleinen Cylinder i geschehen kann, der in der Mitte der oberen Traverse angeordnet ist.During the retraction of the piston, the upper knife carrier is also moved upwards again, which can be done, for example, by the small cylinder i , which is arranged in the middle of the upper cross member.
Der hydraulische Druckcylinder könnte dieselbe Wirkung ausüben, wenn er anstatt waagrecht etwas schräg, d. h. in einem nicht zu grofsen Winkel zur Druckrichtung angeordnetThe hydraulic pressure cylinder could have the same effect if instead of being horizontal slightly oblique, d. H. arranged at a not too large angle to the direction of printing
