Description

TECHNICAL FIELD

[0001] The present invention relates to a stand housing of a stand for rolling a metal rod, wire or tube along a rolling axis. BACKGROUND

[0002] Stands for rolling rod-shaped material to be rolled are known in principle in the production of metal tubes, rods or wires. In this case, the material to be rolled can be rolled to the desired diameter since the caliber is set accordingly. In order to set the caliber of the stand, it is customary to change the distance of the rollers from the rolling axis. The technical solution for setting the position of the rollers relative to the rolling axis is an eccentric adjustment member.

[0003] A stand of the above technical field with an eccentric adjustment member is known, for example, from DE 100 15 340 Al. In DE 100 15 340 Al, a synchronous adjustment of all roller axes and thus of all rollers can be achieved by driving only one eccentric bushing, the adjustment taking place via an adjustment connector provided on the side surface of the stand housing.

[0004] Generally, a plurality of stands is arranged in succession in a rolling mill. Thus, the material to be rolled can be stretched in particular by the difference between the roller speeds of the individual stands and rolled to a smaller diameter.

[0005] Furthermore, the roundness of the material to be rolled is generally not sufficient after passing through one stand, since due to the star-shaped arrangement of the rollers and their relatively small number, the cross section assumes a polygonal shape, the number of sides of the polygon corresponding to the number of rollers of the stand. For example, the material to be rolled rolled by a single three-roller stand has a cross-sectional shape which is not ideally circular but approximately triangular.

[0006] In order to improve the roundness of the material to be rolled, the successive stands are preferably arranged such that in each case the corners of the cross section of the material to be rolled, which leaves the stand, come into contact with the centers of the rollers of the next stand and thus round the cross section of the material to be rolled.

[0007] Thus, in each case, the three rollers of the first and third stands of a rolling mill, for example with four stands, are generally positioned in a so-called "Y arrangement" and in each case the rollers of the stands arranged thereafter, for example the second and fourth stands, are arranged in a so-called "inverted Y arrangement". Due to the alternating arrangement of the rollers and stands in a Y arrangement and an inverted Y arrangement, in each case the corners of the cross section of the material to be rolled are rolled by the rollers of the next stand and thus rounded.

[0008] In the Y arrangement, the lower roll is oriented such that its roll axis is positioned horizontally, i.e. the diameter of the lower roll extends vertically in the viewing direction of the rolling axis. In contrast, in the inverted Y arrangement, it is the roll axis of the upper roll which is positioned horizontally, i.e. the diameter of the upper roll extends vertically in the viewing direction of the rolling axis. In both cases, the roll axes of the other two rolls are positioned at an angle of 120° with respect to the horizontal roll axis in each case. Of course, the arrangement with respect to the horizontal is generally arbitrary, since for the effects described herein it is only important that the rolls are arranged relative to one another.

[0009] The arrangement of the stands one after the other to form a rolling mill is usually carried out using stand bases into which the stands are introduced and held by the stand bases. This makes it possible to exchange stands from the rolling mill, for example for maintenance which is required at regular intervals.

[0010] The stand known from DE 100 15 340 A1 makes it possible to switch between the Y arrangement and the inverted Y arrangement by rotating about 180° about a horizontal axis and allows insertion into the stand base in both orientations. The upper and lower side surfaces of the rectangular stand housing serve as contact surfaces in the stand base.

[0011] The stand positions of the Y arrangement and the inverted Y arrangement can be selected such that the adjustment connector of the eccentric adjustment member arranged on the side surface of the stand housing remains on the same side when the side surface is the side surface which horizontally delimits the stand, i.e. is oriented vertically. The torque-introducing coupling for the drive train with the electric motor and, if necessary, also with the gearbox for driving the rolls with the horizontally oriented roll axis is then positioned on the opposite side surface.

[0012] While the above-described arrangement of the adjustment connector allows good accessibility for manual operation of the adjustment connector from this side, the adjustment connector cannot be easily, i.e. automatically, operated and actuated by so-called remote adjustment, since in order not to hinder access to the stand, the electric motor required for this can not be arranged on this side. SUMMARY

[0013] Against this background, it is an object of the present invention to provide a stand housing of the aforementioned technical field which allows more flexible use within a rolling mill and, in particular, more flexible selection of both the position in the rolling mill and the adjustment configuration as well as a simultaneous compact design of the rolling mill.

[0014] In other words, it is an object to develop a stand housing of the aforementioned technical field which can be modularly arranged in the rolling mill, at different positions and in different positions in the stand base in as universal a manner as possible, such that the radial spacing between the rolls and the rolling axis, i.e. the adjustment, can be adjusted in a plurality of different ways, in different adjustment configurations.

[0015] This object is achieved by a stand housing according to claim 1. Advantageous embodiments of the application emerge from the dependent claims.

[0016] A stand housing for a stand for rolling metal rods, wires or tubes along a rolling axis comprises at least four contact surfaces which are arranged on the outside of the stand housing and which, viewed along the rolling axis, are parallel thereto. Two of the contact surfaces do not adjoin and extend parallel to one another, such that they form parallel contact surfaces, and two other contact surfaces of the contact surfaces adjoin one another, such that they form adjoining contact surfaces. In this case, the adjoining contact surfaces are at an angle of 120° to one another and each of them is at an angle of 120° to one of the parallel contact surfaces. Two parallel contact surfaces or adjoining contact surfaces or parallel and adjoining contact surfaces are designed to receive a slide rail for inserting the stand housing into a stand base.

[0017] These slide rails make it possible for the stand housing to be inserted precisely and securely into the stand base in four different orientations. The arrangement of the contact surfaces and the slide rails makes it possible to switch between different arrangements which in each case can be presented by rotating through 60° about the rolling axis. Viewed along the rolling axis, the contact surfaces are arranged so as to be rotated through approximately 60° about the rolling axis in each case. The contact surfaces which are arranged so as to be rotated through approximately 60° about the rolling axis enclose the above-mentioned angle of 120° with respect to one another. It is particularly preferred for the stand housing to have the shape of a regular hexagon, viewed along the rolling axis, however, the corners can also be rounded or enlarged by chamfering, etc.

[0018] The contact surfaces of the stand housing can be formed by side surfaces of the stand housing or can extend parallel to the side surfaces. In this case, the side surfaces do not have to be flat, but can also comprise steps, protrusions or recesses and openings and can also be formed in multiple parts.

[0019] It is advantageous for each of the contact surfaces to be designed in multiple parts, which have at least two contact edges which are spaced apart along the rolling axis and between which at least one outwardly protruding protrusion is formed. In particular, the protrusion is offset from the contact edges by two steps which extend parallel to the contact edges. In other words, the contact surfaces are arranged so as to be offset inwardly with respect to a protruding portion of the side surface and to surround the protruding portion on both sides along the rolling axis, such that the stand housing rests stably on two spaced-apart slide rails along the rolling axis and thus on a bottom whose width corresponds to the spacing between the slide rails. At the same time, the slide rails provide the possibility for the stand housing to extend between the corresponding stand base side uprights, due to the spacing between them. According to this preferred embodiment, the stand housing thus comprises two times four, i.e. eight, contact edges which are preferably designed to receive one slide rail in each case.

[0020] In a preferred embodiment, each of the contact surfaces is designed for receiving a pair of slide rails. This is particularly preferred in the above-described embodiment comprising outwardly protruding protrusions between the contact surfaces spaced apart along the rolling axis, but is not limited to this embodiment.

[0021] In particular, in this case, one slide rail of the pair of slide rails can be received on each contact edge, respectively. However, it is also possible to provide multiple slide rails for each contact edge, or no slide rail for a contact edge.

[0022] In a preferred embodiment, the contact surfaces comprise threaded holes for fastening the slide rails. This ensures a reliable, detachable, quick and precise mounting of the slide rails on the contact surfaces. However, the slide rails can also be clamped or fastened on the contact surfaces in another way.

[0023] The support for rolling a metal rod, wire or tube along a rolling axis comprises a support housing according to the above description and three rollers, which in each case are positioned on one roller shaft, surround the rolling axis in a star-shaped manner and together form a caliber.

[0024] The support housing is thus designed to receive three rollers, which in each case are positioned on one roller shaft, surround the rolling axis in a star-shaped manner and together form a caliber. In particular, the three roller shafts are mounted in bearing holes of the support housing by means of eccentric bushings, so that the radial spacing of the rollers from the rolling axis is adjustable.

[0025] The star-shaped arrangement of the rollers around the rolling axis means that the rollers or their rotation planes are arranged at an angle of 120° with respect to two adjacent rollers or their rotation planes in each case. This also applies to the roller shafts, the axes of which intersect in addition to the rotation planes of the rollers, but not in the caliber. However, within the support, each roller shaft is at an angle of 120° with respect to the other two roller shafts in each case.

[0026] In the context of the present invention, the caliber means the opening between the three rollers, through which the material to be rolled is guided and in the process is rolled. Its rolling axis, which is orthogonal to the channel formed by the star-shaped arrangement of the three rollers within the rolling surface, extends above the cross-sectional surface. The caliber is not identical to the target or production diameter of the material to be rolled, since the support widens due to the material to be rolled and is not elastically deformed during the rolling process, and since the material to be rolled is not only influenced by the rollers themselves, but its diameter is also influenced elastically and plastically, for example, by the forces between adjacent supports. However, the caliber significantly influences the production diameter.

[0027] In the case of the support of the present invention, the spacing of the rollers from the rolling axis can be set for setting the caliber by rotating the eccentric bushings, i.e. by eccentric adjustment, for example, as known from DE 100 15 340 A1.

[0028] The support housing comprising four contact surfaces positioned at an angle of 120° relative to each other is particularly advantageous for a support comprising three rollers arranged in a star-like manner around a rolling axis, since the relative orientation of the rollers and the contact surfaces match each other. Thus, the support housing can be switched between different variants of a Y-arrangement and an inverted Y-arrangement and then inserted in the support base via one of the mentioned contact surfaces or slides in each case.

[0029] Thus, the support housing can be used more flexibly within the rolling mill and, in particular, a more flexible selection of both the position in the rolling mill and the adjustment configuration, as well as a simultaneous compact design of the rolling mill, is possible.

[0030] The support housing can thus be used in the rolling mill in a modular and very versatile manner, since it can be arranged at different positions and in different positions in the support base.

[0031] Further advantages and developments of the invention emerge from the following description of the drawings and all technical solutions. BRIEF DESCRIPTION OF DRAWINGS

[0040] In the following description of the drawings, identical or corresponding elements are provided with the same reference numerals, and a repeated description is largely avoided.

[0041] Figure 1A is a view along a rolling axis 19 extending in the Z direction of a preferred stand 1 for rolling a metal rod, wire or tube. The stand 1 comprises a stand housing 10 which in the embodiment shown here has a regular hexagonal shape when viewed along the rolling axis 19. The exterior 12 of the stand housing 10 has six side surfaces 14.1 to 14.6 of equal length which are arranged in a rotationally symmetrical manner around the rolling axis 19. Adjacent side surfaces 14.1 to 14.6 merge into one another in regions referred to as corners 16.1 to 16.6. In this case, the corners 16.1 to 16.6 can be marked differently. It comprises the adjoining edges between adjacent side surfaces 14.1 to 14.6 which merge into one another in the corners 16.1 to 16.6, which can be sharp-edged, but are preferably chamfered or rounded. Small intermediate surfaces between adjacent side surfaces 14.1 to 14.6 are also possible in the sense of a significantly oppositely wide chamfer and are still understood as corners 16.1 to 16.6 in the context of the present application. The entry side 15 (not shown in Figure 1A but shown in Figure 1B and the exit side 13 shown in Figure 1A Thus, the stand housing 10 of the embodiments of the present application generally has a regular hexagonal shape, which is characterised, inter alia, in that it has three pairs of side surfaces 14.1, 14.4, 14.2, 14.5, 14.3, 14.6 which are positioned parallel to one another in each case. The stand housing 10 is manufactured as a unit.

[0042] The preferred stand 1 is designed such that the entry side 15 (not shown in Figure 1A is similar to the exit side 13 shown in Figure 1A so that all the features described below for the exit side 13 are found at the same or corresponding positions on the opposite side of the stand housing 10, as is also shown below with reference to the other figures.

[0043] The stand 1 further comprises three rollers 20.1, 20.2, 20.3 which are arranged in a star-like manner around the rolling axis 19. The rollers 20.1 to 20.3 in each case delimit a rotation plane which is angled at 120° with respect to one another and which intersects in the rolling axis 19. The rotation planes of the rollers 20.1 to 20.3 are in each case arranged normal to a pair of side surfaces 14.1 to 14.6 of the stand housing 10. In the region of the rolling axis 19, the rollers 20.1 to 20.3 form a bore 21 therebetween. The bore 21 is in particular surrounded by a rolling surface 22 of each of the rollers 20.1 to 20.3, the rolling surfaces 22 of the rollers 20.1 to 20.3 being formed centrally along the periphery of the respective roller 20.1 to 20.3 as an inwardly concave groove in order to provide the material to be rolled with an outer contour which is as round as possible. However, depending on the material to be rolled, the rolling surfaces 22 can also be designed differently, in particular as flat surfaces or convex surfaces. In Figure 1A It can be seen that the rollers 20.1 to 20.3 are arranged in an inverted Y arrangement, since the upper roller 20.1 is positioned vertically and the two remaining lower rollers 20.2, 20.3 are in each case positioned at an angle of 120° with respect to the vertical orientation of the upper roller 20.1.

[0044] The rollers 20.1 to 20.3 are in each case fixedly positioned on a roller shaft via which the rollers 20.1 to 20.3 are driven. The rotation axis of the roller shaft in each case extends parallel to a pair of side surfaces 14.1, 14.4, 14.2, 14.5, 14.3, 14.6. Furthermore, the rotation axis is arranged transversely to the rolling axis 19 and in a rotationally symmetrical or star-like manner around the axis. Figure 1A The rotation axis of the roller shaft of the upper roller 20.1 in is oriented in the X direction. The rotation axes of the other two roller shafts are in each case inclined at an angle of 120° and 240°, respectively, with respect to the rotation axis of the upper roller shaft. In the roller shafts, in each case, Figure 1A In is shown only the drive-side end 24.1, 24.2, 24.3 which projects out at one of the side surfaces 14.2, 14.4, 14.6 of the stand housing 10. The roller shafts can thus each adjoin an external drive which can thus transmit its rolling torque to the roller shafts and thus to the rollers 20.1 to 20.3 via a coupling.

[0045] The roller shafts extend inside the stand housing 10, wherein also an eccentric adjustment member (not shown) for adjusting the rollers 20.1 to 20.3 via the roller shafts is positioned. The eccentric adjustment member makes it possible to adjust the eccentricity of the rollers 20.1 to 20.3 with respect to the rolling axis 19. Figure 1AIn the X-Y plane, the distance between the roller shafts can be changed and thus the distance between the rollers 20.1 to 20.3 on the one hand and the rolling axis 19 on the other hand. Thus, for a constant caliber 21, different sizes of the caliber 21 can be set and also wear of the rollers 20.1 to 20.3 can be compensated. The eccentric adjustment members form an adjustment mechanism of the rollers 20.1 to 20.3.

[0046] The adjustment mechanism of the rollers 20.1 to 20.3 can be actuated from the outside, since an adjustment connector 30 protruding to the outside near the corner 16.1 is rotated. In Figure 1A the embodiment shown in Figure 1A , the adjustment connector 30 is designed such that it can be actuated both manually and automatically by an electric motor. The adjustment connector 30 is preferably connected to a rotatably mounted gear shaft extending inside the cradle housing 10 and to a bevel gear engaging in a tooth segment of an eccentric bushing of the eccentric adjustment members, which in turn is able to transmit a rotational movement transmitted to it via the bevel gear to the other two eccentric bushings and thus to allow a synchronous adjustment of the rollers. The adjustment mechanism is not shown in detail in .

[0047] The adjustment connector 30 is positioned near the corner 16.1 and the gear shaft connected to the adjustment connector 30 extends parallel to the upper roller shafts in Figure 1A , i.e. in the X direction, the drive-side end 24.1 of which protrudes to the outside of the cradle housing 10 on the opposite side. The adjustment connector 30 is thus essentially positioned opposite the drive-side end 24.1 of the roller shafts extending parallel to the gear shaft. This opposite arrangement implies that the adjustment connector 30 is not covered by the roller motor arranged flush with the drive-side end 24.1 of one of the roller shafts, since the drive-side ends 24.2, 24.3 of the roller shafts adjacent to the adjustment connector 30 are in each case oriented approximately 60° upwards and downwards with respect to the adjustment connector 30 and its gear shaft, so that a large free space is formed between them for the motor coupled thereto, which makes the adjustment connector 30 freely accessible.

[0048] In Figure 1A , the adjustment connector 30 is arranged close to the corner 16.1 and slightly offset upwards with respect to an imaginary horizontal center plane of the cradle housing 10. In this case, the distance between the adjustment connector 30 and the center plane extending parallel to the gear shaft along the Y axis in Figure 1A is less than 10% of the extension of the cradle housing 10 in the Y direction, i.e. between the two opposite side surfaces 14.2, 14.5 of the cradle housing 10. Figure 1A

[0049] Figure 1AThree mounting elements 26.1, 26.2, 26.3 for a guide for the material to be rolled (not shown in Figure 1A ) are shown. The guide can be mounted on the outlet side 13 of the cradle housing 10, which is shown in Figure 1A . The mounting elements 26.1, 26.2, 26.3 can also be arranged on the inlet side 15 (not visible in Figure 1B ), so that a guide for the material to be rolled can be mounted there.

[0050] The guide for the material to be rolled can be, for example, a roller guide, in particular a roller guide 60, as shown by way of example in Figure 1A , or can be a funnel guide. The mounting elements 26.1, 26.2, 26.3 are positioned in a star-shaped manner around the rolling axis 19 and in each case opposite one of the rollers 20.1, 20.2, 20.3 with respect to the rolling axis 19. The three mounting elements 26.1, 26.2, 26.3 are arranged in each case at an angular spacing of 120° around the rolling axis 19.

[0051] Furthermore, three coupling piece clamping regions 50.1, 50.2, 50.6 are arranged on the outlet side 13 of the cradle housing 10 shown in Figure 1A , in the adjacent corners 16.1, 16.2, 16.6 of the cradle housing 10. The coupling piece clamping regions 50.1, 50.2, 50.6 are in each case delimited by two clamping rails 52. The three adjacent corners 16.1, 16.2, 16.6 in which the coupling piece clamping regions 50.1, 50.2, 50.6 are arranged are the corner 16.1 in which the adjustment connector 30 is also arranged and the two corners 16.2, 16.6 adjacent thereto. The coupling piece clamping regions 50.1, 50.2, 50.6 serve to fasten roller guide adjustment connectors 64 (not shown in Figure 1B , but shown in Figure 1A ) firmly on the cradle housing 10. This relative arrangement of the coupling piece clamping regions 50.1, 50.2, 50.6 in the corner 16.1 of the adjustment connector 30 and in the two corners 16.2, 16.6 surrounding these makes it possible for the arrangement and configuration of the cradle 1 in combination with the roller guide and thus for a particular flexibility of the overall system consisting of the cradle 1 and the roller guide to be transferred.

[0052] Figure 1AThe display bracket housing 10 includes four slide rails 40.2, 40.3, 40.4, and 40.5 on the outlet side 13, said rails being arranged parallel to four adjacent side surfaces 14.2, 14.3, 14.4, and 14.5. Slide rails 40.2 to 40.5 are adjacent to each other and extend along the periphery of the hexagonal bracket housing 10 from corner 16.2, including the coupling clamping region 50.2, to corner 16.6, including the coupling clamping region 50.6. Figure 1A In the description, slide rails 40.2 to 40.5 are not arranged on side surfaces 14.2 to 14.5, but are offset inward in the direction of the rolling axis 19. Slide rails 40.2 to 40.5 form a sliding surface that extends outward in the peripheral direction along side surfaces 14.2 to 14.5 on one hand, and outward from the paper plane parallel to the rolling axis 19 and side surfaces 14.1 to 14.6 on the other hand. Figure 1A Extending in the Z direction. Therefore, slide rails 40.2 to 40.5 can serve as contact surfaces in four orientations of the bracket 1, and are particularly designed to facilitate reception of the bracket 1 in the bracket base (not shown), as the bracket 1 can be pushed into the bracket base on slide rails 40.2 to 40.5, and in this case, slide rails 40.2 to 40.5 can also serve as sealing elements. On the opposite inlet side 15 ( Figure 1A On the (not shown) side, four slide rails 40.2 to 40.5 are also positioned opposite to the slide rails 40.2 to 40.5 shown, such that in each case, a pair of slide rails 40.2 to 40.5 on opposite sides can be used to stably mount the bracket 1 in the bracket base.

[0053] The stent 1 further includes Figure 1A The image shows three outlets 42.1, 42.2, and 42.3 on the outlet side 13. Therefore, cooling water, for example intended for use with roller guides, can be supplied through the inlet (…). Figure 1A (Not shown) It is introduced into the support housing 10 at one of the side surfaces 14.1, 14.3, 14.5, guided through the support housing 10 and guided out through one of the outlets 42.1, 42.2, 42.3, and from there fed to the roller guide.

[0054] In addition, Figure 1B On the outlet side 13 and inlet side 15 (not shown in this figure), there are a total of five clamping points 44.2, 44.3, 44.4, 44.5, and 44.6 positioned at the corners 16.2, 16.3, 16.4, 16.5, and 16.6 of the side surface 14 along which the defining slide rails 40.2, 40.3, 40.4, and 40.5 are arranged. These clamping points can absorb the clamping force from the bracket base used to fix the bracket 1.

[0055] Figure 1A The display is in a position relative toFigure 1A the position of the stand 1 from Figure 1B is shown in a position in which the stand 1 is tilted by about 180° around a horizontal axis K, i.e. which extends in the X direction. Thus, Figure 1A is a rear view of the stand 1 according to Figure 1A i.e. showing the entry side 15. In this position of the stand 1, contrary to the position illustrated in Figure 1A the rollers 20.1 to 20.3 are arranged in a Y-arrangement.

[0056] The roller shafts are displaced in parallel with respect to the position of the stand 1 from Figure 1B and thus their drive-side ends 24.1 to 24.3 protrude out of the stand housing 10 in the same direction, but in different positions, in particular mirrored at the respective corners 16.2, 16.4, 16.6. Thus, due to the tilting described above, the shown stand 1 allows for use in rolling mills having both a Y-arrangement and an inverted Y-arrangement of the rollers 20.1 to 20.3 in the same stand base, the drive-side ends 24.1 to 24.3 of the roller shafts only being displaced in translation. This allows for a high flexibility of use of the stand 1 in compact rolling mills. The rolling drives coupled to the drive-side ends 24.1 to 24.3 of the roller shafts in both positions of the stand 1 can be arranged on the same side of the rolling axis 19 for each stand position having an alternating Y-arrangement and inverted Y-arrangement, which makes the space requirements of the overall rolling mill relatively small.

[0057] Due to the tilting around the axis K, the adjustment connector 30 is still arranged in the vicinity of the corner 16.1 of the stand housing 10. It is arranged in a slightly downwardly offset manner with respect to the horizontal center plane of the stand housing 10, in particular mirrored at the corner 16.1. However, the adjustment connector 30 is also easily accessible from the same side in this position of the stand 1, i.e. in the Y-arrangement, and thus particularly suitable for an efficient manual operation of the stand 1 adjacent to the eccentric adjustment member.

[0058] Figure 1A Further shown is a roller guide 60 which is fastened on the stand housing 10 via mounting elements 26.1 to 26.3 which have been described above with reference to Figure 1B and which are also present on the entry side 15 of the stand housing 10 shown in Figure 1B The roller guide 60 is also adjustable, because the rollers of the roller guide 60 can be positioned closer to or further away from the rolling axis 19 by means of a roller adjustment mechanism. For the roller adjustment mechanism, the roller guide 60 is connected via a universal shaft 62 to a roller adjustment connector 64 via which a torque can be applied to the roller adjustment mechanism.

[0059] The roller adjustment connector 64 is attached to the coupling piece clamping area 50.1 on the stand 1 and the clamping rail 52 associated therewith. Due to the arrangement of the mounting elements 26.1 to 26.3 and the coupling piece clamping areas 50.1, 50.2, 50.6 on the stand housing 10, the roller guide 60 can be attached to the stand housing 10 securely, precisely and quickly.

[0060] Furthermore, the water line 66 of the roller guide 60 is visible in Figure 1B . The water line 66 is connected to the water outlet 42.3 through which the cooling water for the guide rollers of the roller guide 60 leaves the stand 10 when the stand is received in the stand base and connected to the water connection of the stand base through which the cooling water is fed to the stand 10 (not shown in Figure 1C ).

[0061] Figure 1A The preferred stand 1 from Figure 1A is shown in a position rotated clockwise about the rolling axis 19 by about 120° from the position shown in Figure 1A . Due to the geometry of the stand 1, the rollers 20.1 to 20.3 are oriented in the same inverted Y arrangement as in the position shown in Figure 1A , and the three drive-side ends 24.1 to 24.3 also extend in the same direction and are positioned at the same positions so that they can be coupled to external motors for exerting the rolling torque in the same way as in the position from Figure 1A . However, in contrast to Figure 1C , the adjustment connector 30 is arranged rotated clockwise by about 120°.

[0062] This arrangement is preferably used to implement remote adjustment of the adjustment mechanism of the rollers 20.1 to 20.3 by external motors. The positioning of the adjustment connector 30 in the position of the stand 1 shown in Figure 1A makes it possible for an external adjustment coupling of an external adjustment motor to engage in the stand base (not shown) with the adjustment connector 30 and to actuate the adjustment connector 30 in order to activate the rollers 20.1 to 20.3. This is different from the case in the positions shown in Figures 1A to 1D and 1B .

[0063] The stand 1 must be able to be pushed into and pulled out of the stand base transversely to the rolling axis 19 in order to be able to be serviced quickly. This requirement in turn means that the stand in Figure 1A must be pushed to the right into the stand base in order to drive the vertical rollers 20.1 in Figure 1C and 1B or the horizontal rollers 20.2 in Figure 1A and 1DThe rolling motor of the roll 20.2 is able to engage with the respective drive-side end 24.1 and 24.2, respectively, because the rolling motor of the roll 20.1 is arranged next to the right side of the rolling axis 19 in Figure 1C and 1B and for 20.2 next to the right side of the rolling axis 19 in Figures 1A to 1D and 1D in order to be coupled to the drive-side end 24.1 and 24.2, respectively.

[0064] This in turn means that in Figure 1A no external adjustment motor can be positioned next to the left side of the rolling axis 19 and thus also next to the left side of the stand 1, i.e. in front of the rolling axis 19 in the insertion direction. Therefore, the positions from Figure 1C and 1B are configured for manual adjustment, i.e. the adjustment connector 30 is actuated by a person, and in this configuration the adjustment connector 30 cannot be actuated by an automatic remote adjustment member or can only be actuated with excessive effort. The positions from Figure 1C and 1D in which the adjustment connector is positioned behind the rolling axis 19 in the insertion direction are configured for remote adjustment, i.e. the adjustment connector 30 is actuated by means of an external motor.

[0065] In the position of the stand 1 shown in Figure 1D the stand is positioned on the slide rail 40.4, while the roll 20.2 is a roll having a vertical rotation plane and the coupling piece clamping region 50.6 is positioned next to the rolling axis 19 in the horizontal direction.

[0066] Figure 1C The preferred stand in the configuration from Figure 1D is shown, i.e. in the configuration with remote adjustment of the adjustment connector 30 in the upper right corner. The position of the stand 1 in Figure 1C can be presented with respect to the position in Figure 1A by tilting the stand 1 by about 180° around an axis K which is inclined by about 120° with respect to the horizontal and thus also by 60°, said axis extending through the corners 16.1 and 16.4. Similar to the transition between the position of the stand 1 from Figure 1B and the position of the stand 1 from Figure 1C a tilting by about 180° around the axis K also takes place after the transition between the position of the stand 1 from Figure 1D and the position of the stand 1 from Figure 1C said axis extending substantially parallel to the gear shaft of the adjustment connector 30. Therefore, after this tilting the orientation of the adjustment connector 30 does not change and the rolls 20.1 to 20.3 are transformed from the inverted Y arrangement shown in Figure 1D into Figure 1DThe Y-shaped arrangement shown in the image is also the same as the reverse.

[0067] Figure 1B and Figure 1B Similarly, the entrance side 15 of display stand 1. Also, as in... Figure 1D In the bracket housing 10, the roller guide 60, which includes the universal joint 62 and the roller adjustment connector 64, is attached to the bracket housing 10 via the clamping rail 52 through the mounting elements 26.1, 26.2, 26.3 and the coupling clamping area 50.2.

[0068] exist Figures 1A to 1D In the position of the bracket 1 shown in the figure, the bracket is positioned on the slide rail 40.3, and the roller 20.3 is a roller with a vertical plane of rotation, and the coupling clamping area 50.2 is positioned in the horizontal direction next to the rolling axis 19.

[0069] Due to the hexagonal shape of the bracket housing 10, the bracket 1 can be arranged in... Figure 2A Of the four positions shown, all are compatible with a similar arrangement of the rolling motor in a rolling mill with a support base. Therefore, both Y-arrangements and inverted Y-arrangements of the rollers can be presented, and similarly, two different configurations in the sense of different orientations and arrangements of the adjustment connector 30, one for manual adjustment and one for remote adjustment. This flexibility is not achieved with the known square support housing, because these are firmly mounted and can only be moved and displaced on or along one side surface of the support housing, which fixes the orientation of the adjustment connector to the constant orientation of the rolling motor.

[0070] Figure 2A It is a perspective view of the inlet side 15 of the preferred bracket 1, wherein the three rollers 20.1, 20.2, 20.3 are arranged in an inverted Y arrangement, and the adjustment connector 30 of the eccentric adjustment member is horizontally oriented to the side.

[0071] Recesses and drilled holes are visible along the outer 12 of the support housing 10, said recesses and drilled holes being provided for receiving roller shafts (in Figure 2A In this configuration, only the drive-side end 24.2 of the roller shaft belonging to roller 20.2 is directly identifiable, along with the adjustment connector 30. Furthermore, it is evident that the clamping point 44.6 on the viewer-facing inlet side 15 is bolted to the opposing clamping point 44.6 on the outlet side 13, allowing the clamping force applied to the clamping points 44.6 to be directly and stably transmitted between them, thus securing the bracket 1 within its bracket housing without causing severe deformation or even damage to sensitive components of the bracket housing 10 due to excessive localized forces. Clamping points 44.2 to 44.5 are designed in the same manner and connected to each other.

[0072] and Figure 2B Same, Figure 2AFrom a different perspective the entry side 15 of the stand 1 is shown, wherein the drive side end 24.1 of the roller shaft of the roller 20.1 is visible. Figure 3A

[0073] Figure 3A 3B Each is a side view of the stand, wherein the three rollers are oriented in an inverted Y arrangement. Figure 3A The corner 16.1 and the side surfaces 14.1 and 14.6 as well as the drive side ends 24.2 and 24.3 of the roller shafts of the rollers 20.2 and 20.3 and the adjustment connector 30 are shown.

[0074] Figure 3A Further two water supply openings 43.2 are shown, which can be connected to water connections in the stand base in order to receive water in the stand housing 10 and to conduct it out via the water outlet 42.2, for example in order to feed it to the water line 66 of the roller guide 60. In Figure 3B In the perspective view, next to the drive side end 24.2 also an air connection 41.2 is visible, via which compressed air can be fed to the stand housing 10 in order to protect the interior of the stand housing 10, in particular the gear box components located therein, for example the eccentric adjustment member, from water penetration by overpressure.

[0075] Figure 3A The corner 16.4 opposite the corner 16.1 from Figure 3B is shown, as well as the side surfaces 14.3 and 14.4 opposite the side surfaces 14.1 and 14.6. Furthermore, both the slide rails 40.3 and 40.4 on both the entry side 15 and the exit side 13 are visible. In ​ In the perspective view, the drive side end 42.1 of the roller shaft of the roller 20.1 is visible at the end face, also one air connection 41.1 and two water supply openings 43.3 are shown.
