Diese Erfindung bezweckt die Herstellung von Vierkanteisen, Rundeisen sowie Walzdraht von quadratischer, runder, ovaler oder flacher Form, und zwar aus einem erhitzten Stab Eisen oder Stahl bei einmaligem Passiren der Maschine, also hr einer Operation, wobei Form und Gröfse der erzielten Gegenstände mit der Form und Gröfse der angewendeten Stangen und je nach den verschiedenen Walzen wechseln.This invention aims at the production of square iron, round iron and wire rod from square, round, oval or flat shape, made from a heated iron or rod Steel when passing the machine once, i.e. during one operation, whereby shape and size of the objects obtained with the shape and size of the bars used and depending on change the different rollers.

Die nach dieser Erfindung hergestellte Maschine besteht aus drei Abtheilungen: den Vorwalzen X, den Mittelwalzen Y und den Fertigwalzen Z des Grundplans, Fig. 5.The machine made according to this invention consists of three sections: the preliminary rolls X, the central rolls Y and the finishing rolls Z of the basic plan, FIG.

Die Vorwalzen und Mittelwalzen stehen 2,785 m, die Mittel- und Fertigwalzen 9,42 m von einander entfernt, welche Zwischenräume indefs je nach Erfordernifs verlängert oder verkürzt werden können. Die letzteren sind so eingerichtet und aufgestellt, wie bisher allgemein üblich, dagegen ruhen die Vor- und Mittelwalzen auf einem langen Gestell und bestehen aus einer Reihe von horizontalen und verticalen Walzen, die paarweise in bestimmten Entfernungen von einander angeordnet sind. Sämmtliche Vorwalzen, sowohl die horizontalen als auch die verticalen, sind glatt, die Mittelwalzen sind ebenfalls sämmtlich glatt bis auf das letzte Horizontalwalzenpaar, welches für Vierkanteisen einen entsprechenden und für Randeisen einen ovalen Einschnitt erhält. Dagegen besteht die Fertigwalze nur aus einem einzigen Paar calibrirter Walzen und zwar je nach der Form des zu bildenden Stabes mit kantigen oder runden Kalibern.The pre-rolls and middle rolls stand 2.785 m from each other, the middle and finish rolls 9.42 m apart removed, which interstices are lengthened or shortened as required can. The latter are set up and set up, as was generally the case up to now, against it the front and middle rollers rest on a long frame and consist of a row of horizontal and vertical rollers, placed in pairs at certain distances from each other are arranged. All pre-rolls, both the horizontal and the vertical, are smooth, the middle rollers are also all smooth except for the last pair of horizontal rollers, which has a corresponding one for square iron and an oval cut is made for the edge iron. In contrast, there is the finishing roll only from a single pair of calibrated rollers, depending on the shape of the one to be formed Rod with angular or round calibers.

Die Horizontal- und Verticalwalzen der Vor- und Mittelwalzen sind mit Führungen versehen, welche von einem horizontalen Walzenpaare bis zu dem nächstfolgenden durch das zwischenliegende vertical angebrachte Walzenpaar laufen.The horizontal and vertical rollers of the front and middle rollers are provided with guides, which from one horizontal pair of rollers to the next one through the intermediate one vertically mounted roller pair run.

Sämmtliche Walzenpaare erhalten ihren Betrieb gemeinschaftlich und sind zu dem Zwecke mit passendem Räderwerk oder Riemen, mit Lagern, Stellschrauben zum Adjustiren etc. versehen. Das Räderwerk der Verticalwalzen mufs wie bei den Verticalwalzen der Universalwalzwerke verstellbar sein.All pairs of rollers maintain their operation jointly and are for this purpose Equipped with a suitable gear train or belt, with bearings, adjusting screws for adjusting etc. The gear train of the vertical rollers must as with the vertical rollers of the universal roller mills be adjustable.

Bei den Vor- sowohl als auch bei den Mittelwalzen wird gewöhnlich das erste und letzte Walzenpaar horizontal angeordnet.In the case of the front as well as the middle rolls, the first and last rolls are usually used Pair of rollers arranged horizontally.

In den Fig. 1 und 2 ist soviel von der Maschine der Länge nach gezeigt, um zwei Paar Horizontal- und ein Paar Verticalwalzen nebst einer Führung zur Anschauung zu bringen. Die übrigen Theile der Maschine werden durch das Hinzufügen solcher verticaler und horizontaler Walzenpaare nebst Führungen, welche in einer Linie mit der Einführung laufen, gebildet, so dafs aus der Beschreibung der Fig. 1, 2 und 4 die Wechselwirkung zwischen Horizontal- und Verticalwalzen, und aus dem Grundplan, Fig. 5, die Wirkung der ganzen Maschine leicht ersehen werden kann.In Figures 1 and 2, as much of the machine is shown lengthwise as two To bring a pair of horizontal and a pair of vertical rollers together with a guide to view. The remaining parts of the machine become more vertical and horizontal with the addition of these Roller pairs and guides, which run in line with the introduction, are formed, so that from the description of Figs. 1, 2 and 4 the interaction between horizontal and vertical rolling, and from the basic plan, Fig. 5, the effect of the whole machine is easy can be seen.

Die aufrecht stehenden Gehäuse oder Gestelle A A, welche die Horizontalwalzen B tragen, sind von gewöhnlicher Construction.The upright housings or racks AA which support the horizontal rollers B are of ordinary construction.

Die Lagerklötze b und Stellschrauben b' sind passend angeordnet.The bearing blocks b and adjusting screws b 'are arranged appropriately.

Diese Horizontalwalzen sind, wie vorhin erwähnt, in geeigneten Abständen paarweise angebracht. As mentioned above, these horizontal rollers are attached in pairs at suitable intervals.

Zwischen je z\vei horizontalen Walzenpaaren befindet sich eine horizontal liegende Führung.A horizontally positioned guide is located between each two horizontal pairs of rollers.

Zwischen den aufrecht stehenden Gehäusen AA und durch die darauf befestigten Vorsprünge A ^l sind horizontale Gestelle oder Gehäuse C angebracht. Horizontal frames or housings C are attached between the upright housings AA and through the projections A ^{l attached thereon.}

In diesen horizontalen Gehäusen befinden sich die Lager d zur Aufnahme eines Paares Verticalwalzen D D. In these horizontal housings are the bearings d for receiving a pair of vertical rollers D D.

d^l d^; sind Adjustirschrauben. d ^l d ^; are adjusting screws.

Die Walzen D D sind sämmtlich glatt, d. h. ihre Flächen sind weder mit Einschnitten nochThe rollers DD are all smooth, ie their surfaces are neither with cuts nor

Claims

Strand rings, nm with the next one Roll pairs to come into contact.

The vertical rollers are arranged at certain distances, so that the cross-section the passing rod is reduced in the desired manner.

The vertical rollers are arranged symmetrically to the horizontal rollers, so that the effect the vertical rollers with the horizontal roller on each side in relation to the Direction becomes the same. . .

A great practical difficulty which had to be overcome is that of guiding the bar to be rolled from one horizontal roller to the next between the vertical rollers in such a way that it receives an entirely uniform pressure on both sides without becoming U-shaped to bend or even to tip over. In order to bring about this and to reduce the cross-section of the metal rod by means of vertical rollers and to compress the edges, the guides G, Fig. 4, mentioned are attached.

Each of these guides when α takes the rod of the present horizontal roller pairs on and provides the same at the opposite end of the next closest α ^l horizontal roller pairs, as indicated by Figs. 1 and 2 is shown.

The length of these guides from α to a ^{1 is provided} with an opening s of such a size that the rod or the center piece can move unhindered and with the necessary accuracy in the entry and exit line '; through the top and bottom panels c and c ^l and through the side. surfaces is held.

The guides run without interruption, through the vertical rollers DD, without hindering them in their movements.

The sides e ¹ are hollowed out as shown in Fig. 2 and 4. ", the aforementioned opening DAF s iiach each side remains uncovered.

These cavities are slightly more rounded than. the vertical rollers, they narrow on each side the way which the bar or piece of metal has to pass up to halfway the reduction to be achieved.

The amount of lateral compression is approximately equal to that on the flat side and sufficient to make the edges sharp and angular and to prevent them from becoming rough or remain uneven.

The parallel upper and lower plates c and c 'of the guides prevent the rod or piece of metal from tipping over or bending in the cross as the rollers pass. can, while the vertical rollers process the edges and deliver the bar to the following horizontal rollers for drawing and rolling.

From this horizontal roller the bar goes through a similar guide of such proportions, like the changed shape of iron. due to another pair of vertical rollers.

These process the bar again, the rolled product becomes the next horizontal rollers fed and s. f., until a product of the desired shape is obtained.

The side plates e and e ^{l of} these. Guides over the narrowed points are slightly inclined or bell-shaped, as shown at η η, Fig. 4, in order to bring the machined rod in the exact direction of the guide, if the same should deviate from it and to prevent the chips from sticking.

The vertical depth of the opening s can be increased or decreased by making the upper plate adjustable in the vertical plane by means of adjusting screws rr.

As already mentioned and shown in Fig. 3, these pairs of rollers and guides are multiplied, so that one can apply a whole series of ways in which the machine forms.

For rolling metals we use three pairs of horizontal and two pairs of pre-rollers Pair of vertical rollers and four pairs of horizontal rollers and three pairs of vertical rollers for the central rollers at; however, the number thereof can be increased or decreased as needed.

To make the drawing clearer, the gear train for the horizontal rollers has been omitted in Figs. i, 2 and 3.

To operate the rolls, gear trains and belts, such as those used in rolling mills, are used. A pair of rollers can also be brought into engagement with the other by coupling to the necks B ¹ , or, furthermore, each pair of rollers can have an independent movement.

The pole must. are introduced into the machine in such a way that they are removed from the latter Roller pairs is delivered in the most perfect way without any fault.

The drive wheels for the vertical rollers are shown at m ; These wheels are made adjustable, as is customary with the vertical rollers in universal rolling mills.

By using such alternating horizontal and vertical rollers with smooth Areas and cuts (caliber) can be edged and round irons of any size without the machine except for the last pair of horizontal rollers in the middle roller to change.

A set of guides is added to the machine for each size of the machine to be manufactured Productes.

The guide plates can be perforated so that the sinter can move the Falling metal.
