TECHNICAL FIELD
[0001] The present invention relates to a stand housing for a stand for rolling a metal rod, wire or tube along a rolling axis, which housing is provided for attaching a roller guide. 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. A stand of the aforementioned technical field is known, for example, from DE 100 15 340 Al.
[0003] 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.
[0004] Furthermore, the roundness of the material to be rolled is generally not sufficient after passing through one stand, since due to the generally 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.
[0005] In order to improve the roundness of the material to be rolled, the successive stands are preferably arranged such that in each case a corner of the cross section of the material to be rolled, which leaves the stand, comes into contact with the center of a roller of the next stand and thus rounds the cross section of the material to be rolled.
[0006] Thus, in each case, for example, the three rollers of the first and third stands of a rolling mill having 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 the Y arrangement and the inverted Y arrangement, in each case a corner of the cross section of the material to be rolled is rolled using the rollers of the next stand and thus rounds the cross section of the material to be rolled.
[0007] In the Y arrangement, the lower roller is oriented such that its roller axis is positioned horizontally, i.e. the diameter of the lower roller extends perpendicularly in the viewing direction of the rolling axis. Conversely, in the inverted Y arrangement, it is the upper roller whose roller axis is positioned horizontally, i.e. the diameter of the upper roller extends perpendicularly in the viewing direction of the rolling axis. In both cases, the roller axes of the other two rollers are positioned at an angle of 120° with respect to the horizontal roller axis in each case. Of course, the arrangement with respect to the horizontal is generally arbitrary, since for the effects described herein it is important only that the rollers are arranged relative to the adjacent stands.
[0008] Switching between different arrangements of the previously cuboid stands is usually performed by rotating, for example, about 180° around a horizontal axis. However, this switching, among other obstacles, also results in the inlet side, i.e. the end face of the stand through which the material to be rolled enters the stand, and the outlet side, i.e. the opposite end face through which the material to be rolled leaves the stand, being interchanged. In other words, the inlet side becomes the outlet side and vice versa.
[0009] Arranging the stands one after the other to form a rolling mill is usually done using a stand base into which the stands are introduced and by which the stands are held. This makes it possible to change the stands from the rolling mill, for example for maintenance that is required periodically.
[0010] In order to prevent the material to be rolled from performing a twisting movement between successive stands, and the point of action of the rollers along the periphery of the material to be rolled being difficult to control, roller guides are known which are usually attached to the stands on the inlet side of the stands. Such a configuration is known, for example, from CN 114 130 828 A.
[0011] A particularly effective roller guide exhibits the possibility of adjusting the caliber centrally between the feed rollers using a roller adjustment mechanism. For this purpose, for example, a shaft, usually a universal shaft, is used for introducing a roller adjustment torque via a roller adjustment connector, i.e. a coupling for the shaft, which can be fastened to the stand.
[0012] Furthermore, there are two basic configurations of the roller adjustment connector, in particular manual adjustment of the rollers and automatic adjustment, which is referred to as remote adjustment. While arranging the roller adjustment connector on the operator side of the stand housing allows good accessibility of the roller adjustment connector from this side for manual operation, the roller adjustment connector cannot be easily operated and actuated automatically, i.e. by so-called remote adjustment, in this arrangement, since in order not to hinder the operator's access to the stand, the motor required for this can not be provided on this side.
[0013] In the prior art, switching between a Y arrangement and an inverted Y arrangement is associated with a large amount of work to modify the stands after the roller guides have been arranged and set up correctly, in particular in the case of roller guides with roller adjustment connectors. SUMMARY
[0014] 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 and the adjustment configuration in the rolling mill, as well as a simultaneous compact design of the rolling mill.
[0015] In other words, the object is to develop a support housing of the above-mentioned technical field, which can be arranged in a mill in a modular manner in as universal a manner as possible at different locations in the support bed and in different positions, with a central adjustment of the roller guide being able to be used quickly and precisely for a plurality of different adjustment configurations of the rollers, manual roller adjustment and automatic remote adjustment.
[0016] This object is achieved by a support housing according to claim 1. Advantageous embodiments of the application emerge from the dependent claims.
[0017] A support housing of a support for rolling metal rods, wires or tubes along a rolling axis has an exterior which, viewed along the rolling axis, comprises at least six side surfaces arranged so as to be rotated in each case by approximately 60° from one another about the rolling axis and two end faces opposite one another, the side surfaces forming a regular hexagon at least in an imaginary extension. The support housing further comprises at least one pair of coupling piece clamping regions arranged in the corners of the hexagon, and each of the clamping coupling regions of the pair is designed to receive a coupling piece of a shaft of a roller guide for a central adjustment of the roller guide. In this case, one coupling piece clamping region of the pair is arranged on one of the end faces of the support housing, and the other coupling piece clamping region of the pair is arranged on the other of the end faces of the support housing.
[0018] In the context of the present application, a side surface is a surface of the support housing which laterally delimits two end faces, in particular a front surface referred to as the entry side and a rear surface referred to as the exit side, through which the rolling axis extends. Viewed along the rolling axis, the side surfaces together form the lateral outer surface of the support housing. The side surfaces are arranged so as to be rotated in each case by approximately 60° from one another about the rolling axis, i.e. adjacent side surfaces enclose an internal angle of 120°. The side surfaces thus form a regular hexagon at least in an imaginary extension, which means that a projection of the support housing along the rolling axis delimits a polygon having at least six sides and corners. In this case, it is also possible for no sharp corners to be provided between adjacent side surfaces, but rather rounded, chamfered or similar transitions which interconnect the straight side surfaces.
[0019] The side surfaces of the support housing can serve as contact surfaces, comprise contact surfaces or run parallel to one contact surface or a plurality of contact surfaces, for example formed by skids, on which the support can be placed in a stable manner, in particular in the support bed. 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 a plurality of parts.
[0020] The corner in the sense of the arrangement of the coupling piece holding areas according to the invention extends from the side surface or in the case of a non-sharp corner its imaginary extension in its direction intersects the peripheral distance of the adjacent corner up to 25%. The arrangement of the coupling piece holding areas, which itself has a peripheral extension in the center of the corner of the regular hexagon formed by the side surface corresponding to the size of the coupling piece is particularly preferred.
[0021] The number and arrangement of the side surfaces of the present invention's cradle housing compared to the rectangular cradle housing with four side surfaces known from the prior art yields the advantage that the cradle can be used in different positions at different locations in the rolling mill in a modular manner and with different configurations regarding the adjustability of the roller guides. In other words, the cradle can be used in a plurality of different orientations, e.g. a Y-arrangement and an inverted Y-arrangement, with different assignments of the end faces as entry or exit sides, with and without roller guides, etc., and with different versions of the roller adjustment of the roller guides, e.g. manual or automatic. Thereby, the number of cradles reserved for the operator of the rolling mill is reduced, because even after the rolling mill is modified with regard to the adjustability of the roller guides between manual and automatic, the same cradle can be used throughout the rolling mill. Thus, the present invention enables a more flexible use within the rolling mill and in particular a more flexible selection of both the position in the rolling mill as well as the roller adjustment configuration, as well as a simultaneous compact design of the rolling mill.
[0022] In particular, the present invention allows a flexible attachment of additional components arranged on or in the cradle housing, in particular a center-adjustable roller guide. In addition, such components can be e.g. operating connections, sliding elements, bearing elements and fastening elements or funnel guides. However, in this respect as well, the present invention allows a very significant modularization of the rolling mill.
[0023] In addition, the limitation of the complexity of the roller arrangement is advantageous, because the arrangement of the drive of the roller shafts in coordination with the arrangement of the adjustment devices not only for the roller shafts but also for the center-adjustable roller guides within the rolling mill is thus simplified.
[0024] In a preferred embodiment, the cradle housing comprises two pairs of coupling piece holding areas, wherein one pair is arranged in a corner of the hexagon and the other pair is arranged in a corner of the hexagon rotated by about 120° offset around the rolling axis. In other words, one of the pairs of coupling piece holding areas is arranged in a first corner and the other of the pair is arranged in a second corner of the hexagon, which is the next corner in the peripheral direction.
[0025] Thus, switching between the two different arrangements, in particular in the case of a three-roller stand, between the Y arrangement and the inverted Y arrangement can be carried out by tilting about a tilting axis which extends through the center of the corner located between the first and second corners and the stand housing, i.e. a tilted tilting axis compared to the conventional horizontal tilting axis in the case of a rectangular stand housing. In this case, the first and second corners exchange their positions after the switching, and the attachment of the roller adjustment connectors, i.e. the coupling for the central adjustment of the roller guide, can be reliably, quickly and precisely carried out at the respective correct end via the coupling holder regions. If the stand housing additionally comprises bearing holes for the adjustment connectors of the rollers of the stand, which holes are arranged in the region of the third corner, this is particularly advantageous. Tilting about a tilting axis which extends through the corners near the positions at which the adjustment connectors for the roller adjustment are located is particularly efficient for the entire rolling mill between the two different arrangements.
[0026] The stand housing preferably comprises three pairs of coupling holder regions, wherein one pair is arranged in a corner of the hexagon and two pairs are arranged at the corners adjacent thereto. In other words, in this preferred embodiment, one pair of coupling holder regions is also located in the third corner which is located between the first and second corners mentioned above, so that the three adjacent corners each have one pair of coupling holder regions.
[0027] This leads to further flexibility, because in the case of switching between the two different arrangements, in particular in the case of a three-roller stand, between the Y arrangement and the inverted Y arrangement, by tilting about a tilting axis which extends through the center of the corner located between the first and second corners and the stand housing, the third corner retains its position. The attachment of the roller adjustment connectors, i.e. the coupling for the central adjustment of the roller guide, can be reliably, quickly and precisely carried out at the respective appropriate corner by means of the coupling holder regions. If the housing additionally comprises bearing holes for the adjustment connectors of the rollers of the stand, which holes are arranged in the region of the third corner, this is particularly advantageous. Tilting about a tilting axis which extends through the corners and near the positions at which the adjustment connectors for the roller adjustment are located is particularly efficient for the entire rolling mill between the two different arrangements.
[0028] Preferably, the coupling holder regions comprise threaded holes for fastening the coupling for the shaft of the roller guide. Thus, the coupling, i.e. the roller adjustment connector, can be attached to the stand housing reliably and firmly.
[0029] In a preferred embodiment, the coupling holder regions are formed in the end faces. This can ensure an even more reliable and installation space-saving attachment of the coupling.
[0030] Advantageously, the stand housing further comprises a clamping rail which is screwed to the coupling holder regions and by means of which the coupling can be oriented or mounted. This allows a simple and precise mounting and orientation of the coupling.
[0031] A preferred stand for rolling a metal rod, wire or tube along a rolling axis comprises a stand housing according to the above description and three rollers each positioned on a roller shaft, in a star-like manner around the rolling axis and together forming a caliber, the three roller shafts are preferably mounted in bearing holes of the stand housing by means of eccentric bushes, so that the radial spacing of the rollers from the rolling axis is adjustable. In particular, the above-described stand housing is very suitable for such a stand, because a synergy effect of the roller arrangement and the geometry of the stand housing occurs as a result, which is derived in particular from the star-like arrangement of the three rollers on the one hand and the similar symmetry of the external hexagon of the stand housing on the other hand.
[0032] The star-like arrangement of the rollers around the rolling axis means that the rollers or their rotation planes are in each case arranged at an angle of 120° with respect to two adjacent rollers or their rotation planes. This also applies to the roller shafts, the axes of which intersect in addition to in the rotation planes of the rollers, but not in the caliber. However, within the stand, each roller shaft is in each case at an angle of 120° with respect to the other two roller shafts.
[0033] In the case of this preferred stand, the spacing of the rollers from the rolling axis can be set by rotating the eccentric bushes, i.e. an eccentric adjustment, for example known from DE 100 15 340 A1, for setting the caliber.
[0034] The stand preferably further comprises an adjustment connector for introducing an adjustment torque in order to adjust the radial position of the roller shafts with respect to the rolling axis for setting the caliber. In this case, at least two adjustment configurations are possible, namely remote adjustment via an external motor and manual adjustment. For this purpose, an external motor or a suitable tool, for example a spanner, must be engaged with the adjustment connector in order to actuate this, i.e. to rotate it. For example, the rotational movement can be transmitted via a gear box into one of the eccentric bushes of the stand. The rotational movement can be transmitted in principle in a known manner from said eccentric bush to the other eccentric bushes of the roller shafts. Thus, all roller shafts can be adjusted synchronously via a single adjustment connector, and the caliber can be set accordingly.
[0035] The adjustment connector is preferably arranged on the outside of the stand housing, i.e. on the lateral outside, in the corners of the hexagon. In this connection, "in the corners of the hexagon" means that the adjustment connector is closer to the corners, i.e. to the transitions between two adjacent side surfaces, than to the center of the side surface. This arrangement of the adjustment connector makes the stand more flexible to use. Thus, the stand can be rotated by about 180° around an axis extending through the corners and the rolling axis, and thereby switched between a Y arrangement and an inverted Y arrangement, without essentially changing the position of the adjustment connector.
[0036] Other advantages and developments of the invention will appear from the following description of the drawings and all technical solutions. BRIEF DESCRIPTION OF DRAWINGS

[0045] 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.
[0046] Figure 1Ais a view along a rolling axis 19 extending in 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 is provided with 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 invention. An entry side 15 (not shown in Figure 1A but shown in Figure 1B and an exit side 13 shown in Figure 1A have a regular hexagonal shape in general as the stand housing 10 of the embodiments of the present invention, which is characterized, 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.
[0047] 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 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.
[0048] The stand 1 further comprises three rolls 20.1, 20.2, 20.3 which surround the rolling axis 19 in a star-like manner. The rolls 20.1 to 20.3 in each case delimit a rotation plane which is angled at 120° with respect to one another and intersects in the rolling axis 19. The rotation planes of the rolls 20.1 to 20.3 are arranged in each case orthogonally to one pair of side surfaces 14.1 to 14.6 of the stand housing 10. In the region of the rolling axis 19, the rolls 20.1 to 20.3 form a caliber 21 therebetween. The caliber 21 is in particular surrounded by a rolling surface 22 of each of the rolls 20.1 to 20.3 which is formed centrally along the periphery of the respective roll 20.1 to 20.3 as an inwardly recessed 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.Figure 1A As can be seen, rollers 20.1 to 20.3 are arranged in an inverted Y configuration because the upper roller 20.1 is vertically positioned, and the two remaining lower rollers 20.2 and 20.3 are positioned at a 120° angle relative to the vertical orientation of the upper roller 20.1 in each case.
[0049] Rollers 20.1 to 20.3 are fixedly positioned on their driven roller shafts in each case. The axis of rotation of the roller shaft extends parallel to a pair of side surfaces 14.1, 14.4, 14.2, 14.5, 14.3, and 14.6 in each case. Furthermore, the axis of rotation is arranged transversely to the rolling axis 19 and is arranged about the axis in a rotationally symmetrical or star-shaped manner. Figure 1A The rotation axis of the upper roller 20.1 is oriented in the X direction. The rotation axes of the other two rollers are correspondingly inclined at angles of 120° and 240° relative to the rotation axis of the upper roller, respectively. In each case, within the roller shafts, Figure 1A Only the drive-side ends 24.1, 24.2, and 24.3 are shown, which protrude outward at one of the side surfaces 14.2, 14.4, and 14.6 of the support housing 10. Thus, each roller shaft can be adjacent to an external driver, which can then transmit its rolling torque to the roller shaft via a coupling, and thus to rollers 20.1 to 20.3.
[0050] The roller shaft extends inside the support housing 10, where an eccentric adjustment member (not shown) is also positioned for adjusting rollers 20.1 to 20.3 via its roller shaft. The eccentric adjustment member allows for... Figure 1A In the XY plane, the spacing between the roller shafts can be changed, thus altering the spacing between rollers 20.1 to 20.3 on one side and the rolling axis 19 on the other. Therefore, for a constant diameter 21, different sizes of diameter 21 can be set, and wear of rollers 20.1 to 20.3 can also be compensated. The eccentric adjustment member forms an adjustment mechanism for rollers 20.1 to 20.3.
[0051] The adjustment mechanism of rollers 20.1 to 20.3 can be actuated externally because the adjustment connector 30, protruding outwards near corner 16.1, is rotated. Figure 1A In the embodiment shown, the adjusting connector 30 is designed to be both manually actuated and automatically actuated by a motor. The adjusting connector 30 is preferably connected to a rotatably mounted gear shaft extending inside the support housing 10, and to a bevel gear meshing in the toothed section of the eccentric bushing of the eccentric adjusting member. The eccentric bushing is then able to transmit the rotational movement transmitted to it via the bevel gear to the other two eccentric bushings, thus allowing for synchronized adjustment of the rollers. The adjusting mechanism in… Figure 1A The details are not shown outside of adjusting connector 30.
[0052] 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 shaft in the Figure 1A , i.e. in the X direction, the drive-side end 24.1 of the upper roller shaft protruding on the opposite side out of the cradle housing 10. The adjustment connector 30 is thus essentially positioned opposite the drive-side end 24.1 of the roller shaft 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 relative to the adjustment connector 30 and its gear shaft, so that a large free space is formed therebetween for the motor coupled thereto, which makes the adjustment connector 30 freely accessible.
[0053] In Figure 1A , the adjustment connector 30 is arranged near the corner 16.1 and slightly offset upwards relative to the imaginary horizontal centre plane of the cradle housing 10. In this case, the spacing along the Y axis in Figure 1A between the adjustment connector 30 and the centre plane extending parallel to the gear shaft, i.e. in the X direction 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.
[0054] Figure 1A Three mounting elements 26.1, 26.2, 26.3 are shown for a guide for the material to be rolled (not shown in Figure 1A ). 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.
[0055] 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 a funnel guide. The mounting elements 26.1, 26.2, 26.3 are positioned in a star-like manner around the rolling axis 19 and in each case opposite one of the rollers 20.1, 20.2, 20.3 relative 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.
[0056] Furthermore, three coupling piece clamping regions 50.1, 50.2, 50.6 are arranged inFigure 1A On the outlet side 13 of the cradle housing 10 shown in the middle, in the cradle housing 10 adjacent corners 16.1, 16.2, 16.6. The coupling piece clamping region 50.1, 50.2, 50.6 is delimited in each case by two clamping rails 52. The three adjacent corners 16.1, 16.2, 16.6 in which the coupling piece clamping region 50.1, 50.2, 50.6 is arranged are the corner 16.1 in which also the adjustment connector 30 is arranged and the two corners 16.2, 16.6 adjacent thereto. The coupling piece clamping region 50.1, 50.2, 50.6 serves for fastening the roller guide adjustment connector 64 (in Figure 1B not shown in the middle, but in Figure 1A shown in the middle) firmly on the cradle housing 10. The relative arrangement of the coupling piece clamping region 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 transferred to the specific flexibility of the entire system consisting of the cradle 1 and the roller guide.
[0057] Figure 1A The cradle housing 10 shown comprises four slide rails 40.2, 40.3, 40.4, 40.5 on the outlet side 13, which rails are arranged parallel to the four adjacent side surfaces 14.2, 14.3, 14.4, 14.5. The slide rails 40.2 to 40.5 adjoin one another and extend along the periphery of the hexagonal cradle housing 10 from the corner 16.2 comprising the coupling piece clamping region 50.2 to the corner 16.6 comprising the coupling piece clamping region 50.6. In the description of Figure 1A , the slide rails 40.2 to 40.5 are not arranged on the side surfaces 14.2 to 14.5, but are offset inward in the direction of the rolling axis 19. The slide rails 40.2 to 40.5 form slide surfaces which on the one hand extend in the peripheral direction along the side surfaces 14.2 to 14.5 and on the other hand extend outward from the paper plane parallel to the rolling axis 19 and the side surfaces 14.1 to 14.6, i.e. in the Z direction in Figure 1A . Thus, the slide rails 40.2 to 40.5 can be used as contact surfaces in four orientations of the cradle 1 and are intended in particular for facilitating the reception of the cradle 1 in a cradle base (not shown), since the cradle 1 can be pushed onto the slide rails 40.2 to 40.5 into the cradle base and in this case the slide rails 40.2 to 40.5 can also be used as sealing elements. On the opposite inlet side 15 Figure 1A (not shown in the middle) the four slide rails 40.2 to 40.5 are also positioned opposite the slide rails 40.2 to 40.5 shown, so that in each case a pair of slide rails 40.2 to 40.5 on the opposite side can be used for stably mounting the cradle 1 in the cradle base.
[0058] 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.
[0059] 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.
[0060] Figure 1A The display is in a position relative to Figure 1A The orientation is achieved by tilting the support 1 about 180° around the horizontal axis K (i.e., its extension in the X direction), resulting in a position derived from... Figure 1B The support 1. Therefore. Figure 1A It is based on Figure 1A The rear view of bracket 1, showing the entrance side 15. In this position of bracket 1, with... Figure 1A The positions described in the text are reversed, with rollers 20.1 to 20.3 arranged in a Y arrangement.
[0061] Roller shaft relative to from Figure 1B The position of the support 1 is parallel to the displacement, and therefore its drive-side ends 24.1 to 24.3 protrude beyond the support housing 10 in the same direction, but are mirrored in different positions, particularly at the corresponding corners 16.2, 16.4, and 16.6. Thus, due to the aforementioned tilt, the illustrated support 1 allows for use in rolling mills with both Y-arrangements and inverted Y-arrangements of rollers 20.1 to 20.3 in the same support base, with the drive-side ends 24.1 to 24.3 of the roller shaft only translated. This allows for a high degree of flexibility in the use of the support 1 in compact rolling mills. The rolling actuators coupled to the drive-side ends 24.1 to 24.3 of the roller shaft in both positions of the support 1 can be arranged on the same side of the rolling axis 19 for each support position with alternating Y-arrangements and inverted Y-arrangements, resulting in relatively small space requirements for the entire rolling mill.
[0062] Due to its tilt around axis K, the adjusting connector 30 is still positioned near corner 16.1 of the bracket housing 10. It is arranged in a manner that is slightly offset downward relative to the horizontal center plane of the bracket housing 10, particularly mirror-image at corner 16.1. However, also in this position of the bracket 1, i.e., in the Y arrangement, the adjusting connector 30 can be easily reached from the same side, and is therefore particularly suitable for efficient manual operation of the bracket 1 adjacent to the eccentric adjusting member.
[0063] Figure 1A Further shown is the roller guide 60, which is fastened to the bracket housing 10 via mounting elements 26.1 to 26.3, which have been referenced above. Figure 1B Described and also exists Figure 1B The roller guide 60 is shown on the inlet side 15 of the support housing 10. 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 to the roller adjustment connector 64 via a universal joint 62, through which torque can be applied to the roller adjustment mechanism.
[0064] The roller guide 64 is attached to the coupling clamping area 50.1 and the associated clamping rail 52 on the bracket 1. Due to the arrangement of the mounting elements 26.1 to 26.3 and the coupling clamping areas 50.1, 50.2, 50.6 on the bracket housing 10, the roller guide 60 can be securely, accurately and quickly attached to the bracket housing 10.
[0065] In addition, the water pipe 66 of the roller guide 60 is in Figure 1B As can be seen, water line 66 is connected to outlet 42.3, through which cooling water for guiding the rollers of roller guide 60 exits the bracket 10. When the bracket is received in the bracket base and connected to the water connector of the bracket base, cooling water flows through inlet 43.3. Figure 1C (Not shown in the image) is fed to the support 10.
[0066] Figure 1A The display is in relation to the source Figure 1A The position of the rolling axis 19 rotated approximately 120° clockwise from the position of the rolling axis 19 Figure 1A The preferred support 1. Due to the geometry of support 1, rollers 20.1 to 20.3 are oriented in accordance with... Figure 1A The same inverted Y arrangement is shown in the diagram, and the three drive-side ends 24.1 to 24.3 also extend in the same direction and are positioned at the same location, allowing them to be coupled to an external motor for use with... Figure 1A The rolling torque is applied in the same manner at the same location. However, withFigure 1C The adjustment connector 30 is in contrast arranged to rotate clockwise about 120°.
[0067] This arrangement is preferably used for implementing remote adjustment of the adjustment mechanism of the rollers 20.1 to 20.3 by an external motor. The positioning of the adjustment connector 30 in the position of the support 1 shown in Figure 1A enables an external adjustment coupling of an external adjustment motor to engage in a support base (not shown) with the adjustment connector 30 and to actuate said adjustment connector 30 in order to adjust the rollers 20.1 to 20.3. This is different from the case in the positions shown in Figures 1A to 1D and 1B .
[0068] The support 1 must be able to be pushed into and pulled out of the support base transversely to the rolling axis 19 in order to be able to be serviced quickly. This requirement in turn means that the support in Figure 1A must be pushed to the right into the support base in order to enable the rolling motor of the vertical roller 20.1 in Figure 1C and 1B or of 20.2 in Figure 1A and 1D to engage with the respective drive-side end 24.1 and 24.2, respectively, since the rolling motor of the roller 20.1 is arranged to the right next to the rolling axis 19 in Figure 1C and 1B and for 20.2 to the right next to the rolling axis 19 in Figures 1A to 1D and 1D in order to be coupled to the drive-side ends 24.1 and 24.2, respectively.
[0069] 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 support 1, i.e. in front of the rolling axis 19 in the insertion direction. Thus, 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 means 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.
[0070] In the position of the support 1 shown in Figure 1D , the support is positioned on the slide rail 40.4, while the roller 20.2 is a roller with a vertical rotation plane, and the coupling clamp region 50.6 is positioned next to the rolling axis 19 in horizontal direction.
[0071] Figure 1C The preferred holder in the configuration from Figure 1D , namely the configuration with remote adjustment of the adjustment connector 30 in the upper right corner. The holder 1 in Figure 1C position can be presented relative to the position in Figure 1A by tilting the holder 1 about an axis K which extends through the corners 16.1 and 16.4 by about 180° relative to the position in Figure 1B . Similar to the transition between the position of the holder 1 from Figure 1C and the position of the holder 1 from Figure 1D , also after the transition between the position of the holder 1 from Figure 1C and the position of the holder 1 from Figure 1D , a tilting about an axis K takes place by about 180°, which extends essentially parallel to the gear shaft of the adjustment connector 30. Thus, after this tilting, the orientation of the adjustment connector 30 is not changed, and the rollers 20.1 to 20.3 are transitioned from the inverted Y arrangement shown in Figure 1D to the Y arrangement shown in , and vice versa.
[0072] Figure 1B Figure 1B As in Figure 1D , the roller guide 60 comprising the cardan shaft 62 and the roller adjustment connector 64 is attached to the holder housing 10 using the clamping rails 52 via the mounting elements 26.1, 26.2, 26.3 and the coupling clamping area 50.2.
[0073] In the position of the holder 1 shown in Figures 1A to 1D , the holder is positioned on the slide rail 40.3, while the roller 20.3 is a roller with a vertical rotation plane, and the coupling clamping area 50.2 is positioned next to the rolling axis 19 in horizontal direction.
[0074] Due to the hexagonal shape of the holder housing 10, the holder 1 can be arranged in the four positions shown in Figure 2A , which are all compatible with a similar arrangement of the rolling motor in a rolling mill with a holder base. Thus, both the Y arrangement and the inverted Y arrangement of the rollers can be presented, and likewise 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. With known square holder housings, this flexibility is not achieved, since these are firmly seated and can only be displaced on or along one side surface of the holder housing, which fixes the orientation of the adjustment connector in a constant orientation of the rolling motor.
[0075] 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.
[0076] 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 opposite clamping point 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.
[0077] and Figure 2B Same, Figure 2A From and Figure 3A The inlet side 15 of the bracket 1 is shown from different perspectives, in which the drive side end 24.1 of the roller shaft of roller 20.1 is visible.
[0078] Figure 3A and 3B Each is a side view of the bracket, in which three rollers are oriented in an inverted Y arrangement. Figure 3A The corner 16.1 and side surfaces 14.1 and 14.6 are shown, as well as the drive side ends 24.2 and 24.3 of the roller shafts of the adjusting connector 30 and rollers 20.2 and 20.3.
[0079] Figure 3A Further shown are two water inlets 43.2, which can be connected to water fittings in the bracket base to receive water from the bracket housing 10 and discharge it via outlet 42.2, for example, to feed it to water line 66 of roller guide 60. Figure 3B In the middle, next to the drive side end 24.2, an air connector 41.2 is also visible. Compressed air can be fed to the bracket housing 10 through the air connector 41.2 so as to protect the interior of the bracket housing 10 (especially the gearbox components located therein, such as the eccentric adjustment member) from water leakage by overpressure.

Furthermore, the slide rails 40.3 and 40.4 are visible on both the inlet side 15 and the outlet side 13. 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, as is one air connection 41.1 and two water supply openings 43.3.
