Upper support for heavy lathes for machining of grooved rollers.

The processing τοτι caliber rolls a.3. for rolling mills on lathes it was previously mentioned that the visual light chisel resulting in the profile was either in exchangeable Xlauenkäaten. or in appropriate boxes, is clamped. These boxes are formed by the upper part of the lathe, which in turn can be attached to a vertical support, which can be shifted to the workpiece axis on the actual longitudinal support. There are also special designs in which the upper support is designed as a transverse support and can be shifted / grounded directly on the longitudinal support ,! eissels to "A ^r ei3t * that will enter the claw aineinge from the side. 3 for

v / enaung

Turning the chisel boxes, the upper support is roughly U-shaped formed, with the legs pointing upwards from the web and horizontally or in their longitudinal direction 90 ° to the vertical axis. The resulting Chisel box gutter is covered at the top by a bridge in which a heavy tensioning screw is attached. The chisel is fed into this closed chisel box from the workpiece side and through from above the clamping screw as well as from the sides by two oppositely directed and penetrating the legs Tensioning screws fastened. This clamping arrangement is located on the side of the chisel blade 3 facing the workpiece, while two parallel to the side screws rear clamping screws adjust the clamped chisel in its angular position relative to the workpiece axis allow a small amount to be adjusted.

The machining is then carried out in such a way that, with the aid of an IC claw box, first a roughing chisel clamped and with it the rough machining is carried out, while then using a chisel box a finishing chisel clamped, this advanced against the workpiece up to the point of use and the fine machining with standing support by adjusting the rear tensioning screws, i.e. by swiveling the Chisel is made.

j? is for the economical machining of grooved rolls

it

It, however, of utmost importance that the tool is well supported as possible _t and one has already been used for this reason "chisel supports, or to the upper support" support were bolted and protruding from the support or the claw box or the bit box length Jieisselschaftes supported *

Depending on the length by which the chisel protruded from the support, the support had to be selected and, if necessary, replaced and screwed back on again *

According to the hiring, the support should now be with the chisel Be connected to a unit in such a way that an extendable, horizontally extending chisel support is arranged below the chisel in the support itself, the one with the chisel around one between the cutting edge and the Terminal point of the chisel lying imaginary or material Axis pivotable, but the two parts are detachable from each other. This is intended to complete the arrangement be that the an upright flat profile and In particular, a chisel support having a rectangular profile is guided in the upper support and is longitudinally displaceable Is. ':

Does the guide for the chisel support in the Support around a play-free leadership, so is a special one

To provide a special articulated movement between the chisel and the chisel support, it is then advisable to let a screw penetrate the chisel vertically from above into the chisel support, whereby the screw should lie between the cutting edge and the clamping point. In this case, DES loosened bit in the bit box once the bit support is AL30 pre coated with or pushed back at the same time supported by daa clamping of the bit by the force acting from above the clamping screw and the bit prop braced, also carrying such Meisel ■ by Torziehen or retracting especially good because it can be guided over greater lengths in the upper support. However, if the chisel and the splice support are to form a fixed unit, care must be taken that the chisel support can also be pivoted in a suitable manner in the upper support around an imaginary axis corresponding to the screw described above, at the same time as the chisel. that by means of suitable guides of the chisel support in the upper support, despite their pivoting, the bending moments are absorbed by the upper support without play.

With such an arrangement, so in the Calibration can be worked practically as before, but the chisel support is essential

- __ — _____ more effective

made more effective and more rigid, so that _? accordingly, the machined surfaces can also be achieved with the greatest possible cleanliness and the subsequent grinding process requires less working time

The same idea of using a chisel support that is longitudinally displaceable in the upper support in Yerblnduag with the chisel can also be applied accordingly to claw boxes, - hats are provided on the two side surfaces of the upper support in which both the chisel support according to the invention and the chisel arranged above it are accommodated and it is tightened by several clamping screws acting from above * However, in order to prevent the chisel support from escaping sexually, it is recommended that the connection between the chisel and the chisel support is no longer pivotable, but longitudinally displaceable, as these chisels, which are only used as roughing files serve, no longer .arrommt on a pivoting, while the chisel support is to be braced laterally with respect to the upper support by means of horizontal screws running in the right direction. Such arrangements can be provided on both sides of the upper support. It goes without saying that the bracing can also take place by means other than screws. In particular, it is possible to continue to maintain the connection between the chisel and chisel support and to provide clamping devices for the chisel support that allow it to be in any longitudinal position To accept senior support

In the drawing, an embodiment for firing is shown, namely shows

Fig. 1 is a side view of a cross support, Fig. 2 is a section along line II-II of Fig. 1, Fig 3 a front view,

Fig. 4 is a side view using the roughing tools and
Fig # 5 is a front view of Fig. 4.

In the upper support 7, a chisel box is formed by the two legs 8, the channel 9 of which is closed by a bridge 10, which in turn is fastened to the legs 8 by means of screws 11. In the middle of the bridge there are two tensioning screws 12, which penetrate the bridge from top to bottom and tighten the chisel 13 from above, which is held laterally by further screws 14 and from the rear by a pressure screw 15. By operating all screws, it is possible to adjust the hot egg in the chopping channel by small amounts and thus to carry out fine machining.

According to the price increase, there is now one below the chisel Chisel support 16 in the shape of a beam with a rectangular Cross-section housed in a corresponding Recess 17 is longitudinally displaceable in the direction of arrow 18 is. The chisel is through a between its cutting edge 19 and the clamping screw adjacent to it 12 arranged further screw 20 connected so that

one

a pivoting of the chisel relative to the chisel support is possible. The MeiBelstütze is _r as shown in Fig. 2 can be seen, secured against pivoting by lining pieces 21, which may also be simultaneously formed as a clamping wedge-shaped pieces serve or to provide laughing ·

When working with the chisel so far by making the screws 14 and 15, the chisel support 16 will always keep its position * but as soon as the screws 14 and 12 can be loosened * the Chisels are pulled out, whereby the chisel support moves together with it Chisel compared to the support according to the innovation is therefore generally the opposite of the previously known supports Always the same and always the same reliable without changing the support.

Fig. 5 shows another embodiment of the Obersuppärtes 7, this having a lateral slot 22 into which further chisel supports according to the invention 22 'inserted and clamped in any position via screws 23 with hammer head 24 · In the form shown, the chisels above the chisel supports 22 have been removed and it is only worked in the manner described above according to Fig. 1 and 2 with the aliber chisel 15, that is to say finished

In the case of using such a top support after. Fig. 3 shows the roughing process in the and 5, with the chisel bars 22 'clamped and the chisels on them 23 'are placed which, after the screws 23 are tightened, by the screws 12 for the calibration chisel corresponding clamping screws 25 are saved,
