Description
Schmiedemaschine mit drei oder mehr in einer Ebene zentral wirkenden Arbeitsbacken. Es werden eine. Reihe von Erzeugnissen durch Schmieden, Pressen oder Walzen hergestellt, wobei besonders das Zuspitzen und Formgeben nur in einer Reihe von Arbeitsvorgängen erreicht wird und dann meist nur unter Bildung eines Grates. Eine genügend weitgehende Formänderung läßt sich nur dann erzielen, wenn die Vorrichtung mit mehreren zentral tvirkenden Arbeitsbacken versehen ist. Die bisher bekannten Vorrichtungen dieser Art konnten aber die Bildung eines Grates nicht verhindern, weil die Arbeitsbacken sich voneinander entfernten und keine geschlossene Form bildeten.Forging machine with three or more centrally acting in one plane Working jaws. There will be a. Range of products by forging, pressing or Rolling produced, especially the tapering and shaping only in one row is reached by work processes and then usually only with the formation of a ridge. A sufficiently extensive change in shape can only be achieved if the device is provided with several centrally acting working jaws. The ones known so far Devices of this kind could not prevent the formation of a burr, because the working jaws moved apart and did not form a closed shape.
Dies ist bei der vorliegenden Erfindung dadurch erreicht, daß die Arbeitsbacken in Druckknöpfen quer zur Arbeitsrichtung verschiebbar gelagert sind und durch Federn gegen die Nachbarbacken gedrückt werden, so daß sie in jeder Maschinenstellung eine auf dem äußeren Umfang geschlossene Arbeitsmatrize bilden.This is achieved in the present invention in that the Working jaws are mounted displaceably transversely to the working direction in snaps and are pressed by springs against the neighboring jaws, so that they are in every machine position form a working die that is closed on the outer circumference.
Ein Ausführungsbeispiel der Erfindung ist in den Fig. i und 2 dargestellt.An embodiment of the invention is shown in FIGS.
Fig. i ist eine Draufsicht auf eine solche Maschine, bei welcher zur Verdeutlichung des Getriebes die eine Hälfte im Schnitt a-b der Fig. 2 gezeigt ist. Fig. i ist eine Stirnansicht der Bedienungsseite. Der vordere Teil des unteren Druckkopfes ist im Schnitt gezeichnet, wodurch die Druckbacke und die seitliche Druckfeder sichtbar wird. Die obere Druckbacke mit Schlitten und Antriebshebel ist in Fig. i nicht eingezeichnet, da das Bild sonst undeutlich würde.Fig. I is a plan view of such a machine, in which for Clarification of the transmission, one half of which is shown in section a-b of FIG. Figure i is an end view of the operator side. The front part of the lower printhead is drawn in section, whereby the pressure jaw and the lateral compression spring are visible will. The upper jaw with slide and drive lever is not shown in Fig. otherwise the picture would be indistinct.
1, 2, 3, q. sind die Druckbacken; sie sitzen in Druckköpfen 5, 6, 7, 8, welche als Schlitten ausgeführt sind und durch Hebel g, io (Fig. i) bewegt werden; bei starken Drücken kann die Bewegung auch durch Kniehebel erfolgen. Die Hebel g, iö haben ihre Drehpunkte in den Bolzen 11, 12. Das vordere Ende 13 ruht in Gleitschuhen 14, während das entgegengesetzte Ende eine Rolle 15 trägt. Die Rollen 15 der vier Hebel rollen auf einer durch das Zahnrad 16 angetriebenen Scheibe 17 ab. Diese Scheibe besitzt Erhöhungen (Knaggen) entsprechend der Zahl der Rollen. Bei der Drehung der Scheibe 17 werden die Hebel und somit die Druckbacken gleichzeitig bewegt. Durch Federn 18 werden die Hebel in steter Anlage an die Scheibe 17 gehalten und die Druckköpfe zurückgezogen, das Kaliber somit geöffnet. ` Die Backen 1, 2, 3, .4 sind in den Schlitten 3, 6, 7, 8 quere erschieblich angeordnet, wie dies in Fig. i bei Backe 4 und Schlitten 8 zu sehen ist: Durch in Ansätzen 21 der Schlitten 5, 6, 7, 8 angebrachte Federn 22, deren Spannung durch Schrauben 23 veränderlich ist, werden die Backen 1, 2, 3,_4 je in den diagonalen Fugen gegen die im Urzeigersinne folgende, benachbarte Backe gedrückt, so daß auch. bei Verschleiß der Backen oder der Schlitten der von den Backen gebildete Trichter geschlossen bleibt.1, 2, 3, q. are the jaws; they sit in print heads 5, 6, 7, 8, which are designed as slides and moved by levers g, io (Fig. I) will; in the case of strong pressures, the movement can also be carried out using knee levers. the Levers g, iö have their pivot points in the bolts 11, 12. The front end 13 rests in sliding shoes 14, while the opposite end carries a roller 15. The roles 15 of the four levers roll on a disk 17 driven by gear 16 away. This disc has elevations (lugs) corresponding to the number of rollers. When the disk 17 is rotated, the levers and thus the pressure jaws become simultaneously emotional. The levers are kept in constant contact with the disk 17 by springs 18 and the printheads withdrawn, thus opening the caliber. `Jaws 1, 2, 3, .4 are arranged transversely in the carriages 3, 6, 7, 8, as shown in FIG Fig. I at jaw 4 and slide 8 can be seen: Through in lugs 21 of the slide 5, 6, 7, 8 attached springs 22, the tension of which can be changed by screws 23 is, the jaws 1, 2, 3, _4 are each in the diagonal joints against the clockwise following, adjacent jaw pressed, so that too. if the jaws are worn or the slide of the funnel formed by the jaws remains closed.
Sollen lange Stäbe bearbeitet -,verden,- so können die Stäbe durch das Rohr ig, welches durch die hohle Antriebsachse 2o geht, hindurchgeführt werden, so daß die Schmiedearbeit an beliebiger Stelle des Stabes ausgeführt werden kann, was besonders bei Gitterarbeiten von Vorteil ist.If long rods are to be processed -, verden, - the rods can go through the tube ig, which goes through the hollow drive shaft 2o, is passed through, so that the forging can be done anywhere on the rod, which is particularly advantageous when working with grids.
