Rolling mill system with horizontal and vertical smooth pairs of rolls together

Engaged guides.

Patented in the German Empire on January 15, 1878.

This by Mr. Bernard Lauth in Howard, Pennsylvania, Ver. St., made invention aims the production of a thin, flat, wide product, such as B. iron band, Nail plates etc. from one. heated bar of iron when the machine is passed once, so in one operation.

The shape and size of the objects obtained change with the shape and size of the applied rod and depending on the different rollers.

The machines made according to this invention consist of a long frame or Enclosures, or a series of vertical and horizontal enclosures or racks that form a Series of horizontal and vertical smooth rollers, which are paired in certain Distances are arranged from one another and maintain their operation jointly.

These pairs of rollers are provided with guides, one of which is horizontal On the other hand, the roller pairs run through the vertically attached roller pair in between.

All of the rollers have a suitable gear train, bearings, and adjusting screws for adjusting etc. as required by the movement of such rollers.

The first pair of rollers is usually arranged vertically, the last one horizontally.

This machine can be used for rolling all metals that can be rolled.

The horizontal rollers are set in motion by a suitable gear train, as is usually the case which serves metal rollers, driven.

The gear train of the vertical rollers must, as with the vertical rollers of the universal roller mills, be adjustable.

Fig. 1 is a vertical length average of a part of the machine in which, as far as it is concerned is required, the work is presented.

Fig. 2 is a top view of this part of the machine.

Figure 3 is a side elevation of the entire machine on a smaller scale, partly in section.

Figure 4 is a perspective view of the guides used.

In Figures 1 and 2 so much of the machine is shown lengthwise by two pairs Bringing horizontal and a pair of vertical rollers and a guide to view.

The other part of the machine becomes more vertical and horizontal by the addition of these Roller pairs and guides, which run in a line with the introduction, are formed, see above that from the description of FIGS. 1, 2 and 4 the effect of the entire machine, as in FIG. 3 can be easily seen.

The upright housings or racks AA which support the smooth horizontal rollers B are of ordinary construction.

The bearing blocks b and adjusting screws b 'are arranged appropriately.

As mentioned above, these horizontal rollers are attached in pairs at suitable intervals.

There is a horizontal guide between every two horizontal roller pairs.
. Horizontal racks or housings are attached between the upright housings AA and through the projections A 'attached thereon.

In these horizontal housings are the bearings d for receiving a pair of vertical rollers DD.

d ^l d ' are adjusting screws.

The rollers DD are also smooth, ie the surfaces of these, as well as the horizontal rollers, are neither provided with incisions nor rings in order to come into contact with the closest pairs of rollers.

The vertical rollers are arranged at certain distances, so that the cross-section the bar, strip or plate passing through is reduced in the desired manner.

The vertical rollers are symmetrical 7; arranged on the horizontal rollers, so that the movement of the vertical rollers with the horizontal roller on each side becomes the same in relation to the direction. '"\.

A great practical difficulty which must be overcome is the inclination of one relatively wide, thin strip of iron or sheet iron to bend into a U-shape or to tip over.

One edge becomes higher than the other as soon as there is lateral pressure from the rollers, to reduce the width or to condense the edges.

Claims (1)

In order to overcome this inconvenience and to reduce the cross-section of the strip, band, or plate by means of vertical rollers, or to compact the edges, the guides G, Fig. 4, mentioned above are provided. Each of these guides takes at a the rod, strip or plate from the present horizontal roller pair, and delivers the same at its opposite end a ^{1 to} the closest horizontal roller pair, as shown by FIGS. These guides are provided along their length from α to 'with an opening ί of such a size that the rod or piece of metal can move freely and with the. necessary accuracy in the entry and exit line is maintained by the upper and lower plates c and c 'and by the side surfaces. The guides run without interruption through the vertical rollers DD without preventing the same in their movements. The sides e ^x are so hollowed out, as shown in Figs. 2 and 4, that the aforementioned opening s remains partially uncovered on each side. These cavities are a little more rounded than the vertical rollers, they narrow on each one Side the way which the rod or piece of metal has to pass, up to halfway through reduction to be achieved. The amount of lateral compression is usually small and sometimes scarcely sufficient, to make the edges sharp and angular, and to prevent them from becoming rough or uneven stay. The parallel upper and lower plates c and c ^{1 of} the guides prevent the bar or piece of metal from tipping over or bending in the cross when passing the rolls, while the vertical rolls work the edges and deliver the bar to the next horizontal rolls for drawing and rolling . From this horizontal roller the bar goes through a similar guide of such proportions, like the changed shape of the iron caused by a different 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 it should deviate from it and that To prevent the chips from seizing up. The vertical depth of the opening ί 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, if these pairs of rollers and guides are multiplied, so that a whole series of which the machine forms, can apply. For rolling metals I use four pairs of horizontal and four pairs of vertical rollers but this number can be increased or decreased. To make the drawing clearer, the gear train for the horizontal rollers has been omitted. To operate the rollers, gear trains are used, such as. These are used at Walz \ verken, one pair of rollers can also be brought into engagement with the other by coupling to the necks B ', or each pair of rollers can have an independent movement. The bar must be inserted into the machine in such a way that it is removed from the last pair of rollers is delivered in the most perfect form without any error. The drive wheels for the vertical rollers are shown at in ; These wheels are made adjustable, as is customary with the vertical rollers in universal rolling mills. By using rollers with smooth surfaces, you can get flat, thin iron or Roll any other malleable metal of any size without changing the machine. A set of guides is added to the machine for each size of the machine to be manufactured Productes. The guide plates can be punched to allow the scale to move of the metal falling down. Patent Claims: The application of a system of two or more horizontal ones and two or more vertical, smoothly faced rollers with a common lead-in line, in connection with guides that guide the metal to be processed between the vertical rollers. The combination of a vertical pair of rollers for rolling the edges of the metal with Guides which run between the rollers so that the edges of the metal are unobstructed can be edited. The vertical rollers DDm connection with a guide G, which is fixed at the top and bottom and open on the sides between the rollers and is provided with vertical or inclined sides near the rollers as in η η . The combination of adjustable horizontal and vertical rollers with smooth surfaces, with guides between the latter, which can be interchanged, so that by adjusting the rollers and changing the guides, metal strips, straps etc. and plates can be rolled in a wide variety of cross-sections. For this purpose I sheet drawings.
