Description

Technical Field

[0001] The utility model relates to a bracket shell of a bracket used for rolling a metal rod, a wire or a pipe along a rolling axis. The shell is provided for attaching a roller guide. Background Art

[0002] In principle, a support for rolling a rod-shaped material to be rolled is known in the production of metal tubes, rods or wires. In this case, the material to be rolled can be rolled to the desired diameter because the caliber is set accordingly. For example, a support in the above technical field is known from DE 10015340A1.

[0003] Typically, a plurality of stands are arranged in series 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 usually insufficient after passing through a stand, since due to the usual 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 by a single three-roller stand has a cross-sectional shape that is not a perfect circle but rather approximately a triangle.

[0005] In order to improve the roundness of the material to be rolled, the consecutive stands are preferably arranged so that in each case the corners of the cross section of the material to be rolled leaving a stand come into contact with the roller centres of the next stand and thus round off 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 usually 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". Since the rollers and stands are arranged alternately in the Y arrangement and the inverted Y arrangement, in each case, the corners of the cross section of the material to be rolled are rolled by the rollers using the lower stand, and the cross section of the material to be rolled is thus rounded.

[0007] In the Y arrangement, the lower roller is oriented so that its roller axis is horizontally positioned, i.e. the diameter of the lower roller extends vertically in the viewing direction of the rolling axis. In contrast, in the inverted Y arrangement, it is the roller axis of the upper roller that is horizontally positioned, i.e. the diameter of the upper roller extends vertically in the viewing direction of the rolling axis. In both cases, the roller axes of the other two rollers are positioned at an inclination of 120° in each case relative to the horizontal roller axis. Of course, the arrangement relative to the horizontal is generally arbitrary, since for the effects described herein, only the relative arrangement of the rollers relative to the adjacent supports is important.

[0008] The switch between the different arrangements of the previous cuboid supports is usually performed by, for example, rotating about 180° around a horizontal axis. However, this switch also causes, among other obstacles, the inlet side (i.e. the end face of the support through which the material to be rolled enters the support) and the outlet side (i.e. the opposite end face through which the material to be rolled leaves the support) to be interchanged. In other words, the inlet side becomes the outlet side and vice versa.

[0009] The arrangement of the stands one after another to form a rolling mill is usually carried out using a stand base into which the stands are introduced and by which the stands are held. This makes it possible to replace the stands from the rolling mill, for example for regularly required maintenance.

[0010] In order to prevent the rolled material from performing twisting movements between successive stands, and the point of action of the rollers along the periphery of the rolled material being difficult to control, roller guides are known, which are usually attached to the stands on their inlet side. Such a configuration is known, for example, from CN 114 130 828A.

[0011] Particularly effective roller guides offer 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 cardan shaft, is used to introduce the roller adjustment torque via a roller adjustment connector (i.e. a coupling for the shaft), which can be fastened to a support.

[0012] Furthermore, there are two basic configurations of roller adjustment connectors, in particular manual adjustment of the rollers and automatic adjustment known as remote adjustment. Although arranging the roller adjustment connector on the operator side of the housing of the support allows good accessibility for manual operation of the roller adjustment connector from this side, the roller adjustment connector cannot be easily operated and actuated automatically (i.e. by so-called remote adjustment) in this arrangement, since the motors required for this may not be provided on this side in order not to hinder the operator's access to the support.

[0013] In the prior art, switching between the Y arrangement and the inverted Y arrangement so that the roller guides are correctly arranged and modified after the bracket is set is associated with a large amount of work, especially if the roller guides have roller adjustment connectors. Utility Model Content

[0014] Against this background, the object of the invention is to provide a support housing according to the above technical field, which allows a more flexible use within a rolling mill and in particular a more flexible choice of both position and adjustment configuration in the rolling mill and a simultaneously compact design of the rolling mill.

[0015] In other words, the aim is to develop a support housing of the aforementioned technical field in such a way that it can be modularly arranged in a rolling mill in a manner that is as versatile as possible, roller guides with central adjustment being able to be used quickly and precisely for a number of different adjustment configurations of the rollers, manual roller adjustment and automatic remote adjustment at different positions in the support base and in different positions.

[0016] The 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 offset by about 60° about the rolling axis and two end surfaces opposite to each other, the side surfaces forming a regular hexagon at least in an imaginary extension. The support housing further comprises at least one pair of coupling clamping areas arranged in the corners of the hexagon and each of the clamping coupling areas of the pair is designed to receive a coupling of the shaft of the roller guide for centering adjustment of the roller guide. In this case, the coupling clamping areas of the pair are arranged on one of the end surfaces of the support housing and the other coupling clamping area of ​​the pair is arranged on the other of the end surfaces of the support housing.

[0017] In the context of the present invention, a side surface is a surface of the support shell that laterally delimits two end surfaces, in particular a front surface, referred to as the inlet side, and a rear surface, referred to as the outlet side, through which the rolling axis extends. Viewed along the rolling axis, the side surfaces together form a lateral outer surface of the support shell. The side surfaces are arranged so as to be offset from each other by approximately 60° rotation about the rolling axis in each case, i.e. adjacent side surfaces enclose an internal angle of 120°. Thus, the side surfaces form a regular hexagon at least in an imaginary extension, which means that the projection of the support shell along the rolling axis defines a polygon with at least six sides and corners. In this case, it is also possible to provide, instead of sharp corners, rounded corners, chamfers or similar transitions between adjacent side surfaces, which interconnect the straight side surfaces.

[0018] The side surface of the support housing can serve as a contact surface, comprises a contact surface or extends parallel to a contact surface or multiple contact surfaces, for example formed by a slide rail, on which the support can rest in a stable manner, in particular in a support base. The side surface does not have to be flat, but can also comprise steps, protrusions or recesses and openings, and can also be formed in multiple parts.

[0019] A corner in the sense of the arrangement of the coupling clamping area according to the invention extends from a side surface or, in the case of a non-pointed corner, from a point in its direction at which its imaginary extension intersects the peripheral spacing of the adjacent corner by up to 25%. An arrangement of the coupling clamping area, which itself has a peripheral extension corresponding to the size of the coupling in the center of a corner of a regular hexagon formed by the side surfaces, is particularly preferred.

[0020] Compared to the rectangular support housing with four side surfaces known from the prior art, the number and arrangement of the side surfaces of the support housing of the utility model results in the following advantages: the support can be used in a modular manner in different positions at different locations in the rolling mill and in different configurations regarding the adjustability of the roller guide. In other words, the support can be used in a plurality of different orientations, for example a Y arrangement and an inverted Y arrangement, with different assignments of the end faces as the inlet side or the outlet side, with and without roller guides, etc., and with different versions of the roller adjustment of the roller guides (for example manual or automatic). As a result, the number of supports reserved for the operators of the rolling mill is reduced, because the same support can be used universally throughout the rolling mill even after the rolling mill has been modified with respect to the adjustability of the roller guides between manual and automatic. As a result, the utility model enables a more flexible use within the rolling mill, and in particular a more flexible choice of both the position in the rolling mill and the roller adjustment configuration, and a simultaneously compact design of the rolling mill.

[0021] In particular, the invention allows the flexible attachment of additional components arranged on or in the support housing, in particular center-adjustable roller guides. In addition, such components may be, for example, operating connections, sliding elements, bearing elements and fastening elements or funnel guides. However, also in this respect, the invention allows a very significant modularization of the rolling mill.

[0022] Furthermore, the limitation of the complexity of the roller arrangement is advantageous, since the arrangement of the drive of the roller axles in conjunction with the arrangement of the adjustment device both for the roller axles and for the centrally adjustable roller guides in the rolling mill is thereby simplified.

[0023] In a preferred embodiment, the support housing comprises two pairs of coupling clamping areas, one pair of which is arranged in the corners of the hexagon and the other pair is arranged in the corners of the hexagon rotated about 120° offset around the rolling axis. In other words, one of the pair of coupling clamping areas is arranged in the first corner and the other of the pair is arranged in the second corner of the hexagon, which is the next corner in the peripheral direction.

[0024] Thus, switching between two different arrangements, in particular in the case of a three-roller support, between a Y arrangement and an inverted Y arrangement, can be performed by tilting about a tilting axis, which extends through a corner located between the first and second corner and the center of the support housing, i.e., a tilting axis that is tilted compared to the conventional horizontal tilting axis in the case of a rectangular support housing. In this case, the first and second corners interchange their positions after switching, and the attachment of the roller adjustment connector, i.e., the coupling for the center adjustment of the roller guide, can be performed reliably, quickly and accurately at the respective correct end via the coupling clamping area. This is particularly advantageous if the support housing additionally comprises bearing holes for the adjustment connectors of the rollers of the support, which holes are arranged in the region of the third corner. Switching between two different arrangements along a tilting axis extending through the corner near the position where the adjustment connector for roller adjustment is located is particularly efficient for the entire rolling mill.

[0025] The bracket housing preferably includes three pairs of coupling member clamping areas, one of which 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, a pair of coupling member clamping areas is also positioned in a third corner positioned between the first and second corners, so that each of the three adjacent corners is provided with a pair of coupling member clamping areas.

[0026] This leads to further flexibility, since in the case of two different arrangements, in particular in the case of a three-roller support, when switching between a Y arrangement and an inverted Y arrangement, the third corner maintains its position by tilting about a tilting axis extending through a corner positioned between the first and second corner and the center of the support housing. The attachment of the roller adjustment connector, i.e. the coupling for the center adjustment of the roller guide, can be carried out reliably, quickly and precisely at the respectively suitable corner by means of the coupling clamping area. This is particularly advantageous if the housing additionally comprises bearing holes for the adjustment connectors of the rollers of the support, which holes are arranged in the region of the third corner. Switching between two different arrangements along a tilting axis extending through the corner and in the vicinity of the position at which the adjustment connector for roller adjustment is positioned is particularly efficient for the entire rolling mill.

[0027] Preferably, the coupling clamping area comprises a threaded hole for fastening the coupling for the shaft of the roller guide.Therefore, the coupling, ie the roller adjustment connector, can be reliably and firmly attached to the bracket housing.

[0028] In a preferred embodiment, the coupling element clamping region is formed in the end face. This can ensure an even more reliable and installation space-saving attachment of the coupling element.

[0029] Advantageously, the support housing further comprises a clamping rail which is screwed into the coupling clamping region and by means of which the coupling can be oriented or mounted. This allows a simple and precise mounting and orientation of the coupling.

[0030] 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 axle, surrounding the rolling axis in a star-shaped manner and together forming a caliber, the three roller axles preferably being mounted in bearing holes of the stand housing by means of eccentric bushings, 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, since a synergistic effect of the roller arrangement and the geometry of the stand housing thus occurs, which synergistic effect is derived in particular from the similar symmetry of the star-shaped arrangement of the three rollers on the one hand and the regular hexagon of the outer part of the stand housing on the other hand.

[0031] The star-shaped arrangement of the rollers around the rolling axis means that the rollers or their planes of rotation are arranged at an angle of 120° in each case relative to two adjacent rollers or their planes of rotation. This also applies to roller axes, whose axes intersect except in the plane of rotation of the rollers, but not in the bore. However, within the support, each roller axis is at an angle of 120° in each case relative to the other two roller axes.

[0032] In the case of this preferred support, the distance of the rollers from the rolling axis can be adjusted by rotating an eccentric bush (ie, eccentric adjustment as known, for example, from DE 100 15 340 A1) for setting the caliber.

[0033] The support preferably further comprises an adjustment connector for introducing an adjustment torque in order to adjust the radial position of the roller shaft relative to the rolling axis for setting the caliber. In this case, at least two adjustment configurations, namely remote adjustment via an external motor and manual adjustment are both possible. To this end, an external motor or a suitable tool (such as a wrench) must be engaged with the adjustment connector in order to actuate it, i.e., rotate it. For example, the rotational movement can be transmitted to one of the eccentric bushings of the support via a gearbox. The rotational movement can be transmitted from the eccentric bushing to other eccentric bushings of the roller shaft in a manner known in principle. Therefore, all roller shafts can be adjusted synchronously via a single adjustment connector, and the caliber can be set accordingly.

[0034] The adjustment connector is preferably arranged on the outside of the support shell, that is, on the lateral outside, in the corner of a regular hexagon. In this connection piece, "at the corner of a regular hexagon" means that the adjustment connector is closer to the corner than the center of the side surface, that is, closer to the transition between two adjacent side surfaces. This arrangement of the adjustment connector allows the support to be used more flexibly. Therefore, the support can be rotated about 180° around an axis extending through the corner and the rolling axis, and thereby switch between a Y arrangement and an inverted Y arrangement without substantially changing the position of the adjustment connector.

[0035] Other advantages and developments of the present invention are apparent from the following description of the accompanying drawings and all technical solutions. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In the following description of the drawings, the same or corresponding elements are provided with the same reference numerals, and repeated description is largely avoided.

[0045] Figure 1A1 is a view along a rolling axis 19 extending in the Z direction of a preferred stand 1 for rolling metal rods, wires or tubes. The stand 1 comprises a stand housing 10 which, in the embodiment shown herein, is in the shape of a regular hexagon 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 around the rolling axis 19 in a rotationally symmetrical manner. Adjacent side surfaces 14.1 to 14.6 merge with each other in a region referred to as a corner 16.1 to 16.6. In this case, the corner 16.1 to 16.6 may be differently labeled. It comprises adjacent edges between adjacent side surfaces 14.1 to 14.6 merging with each other in the corner 16.1 to 16.6, which edges may be sharp, 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 clearly relatively wide chamfers and are still understood in the context of the present invention as corners 16.1 to 16.6. Figure 1A Not shown in, but in Figure 1B (displayed in) and Figure 1A The outlet side 13 shown in the figure thus has, like the support housing 10 of the embodiment of the invention, a generally regular hexagonal shape, characterized in particular in that it has three pairs of side surfaces 14.1, 14.4, 14.2, 14.5, 14.3, 14.6 which are in each case situated parallel to one another. The support housing 10 is manufactured in one piece.

[0046] Preferably, the support 1 is designed so that the inlet side 15 (at Figure 1A Not shown) Similar to Figure 1A 1 , so that all features described below for the outlet side 13 are found at the same or corresponding locations on the opposite side of the bracket housing 10, as also shown below with reference to other figures.

[0047] The stand 1 further comprises three rollers 20.1, 20.2, 20.3 surrounding the rolling axis 19 in a star-shaped manner. The rollers 20.1 to 20.3 define in each case a plane of rotation which is at an angle of 120° relative to each other and intersects in the rolling axis 19. The planes of rotation of the rollers 20.1 to 20.3 are arranged in each case orthogonally 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 caliber 21 therebetween. The caliber 21 is in particular surrounded by a rolling surface 22 of each of the rollers 20.1 to 20.3, the rolling surface 22 of the rollers 20.1 to 20-3 being formed as a concave groove centrally along the periphery of the respective rollers 20.1 to 20.3 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 surface 22 can also be designed differently, in particular as a flat surface or a convex surface. Figure 1A In FIG. 2 , 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 positioned at an angle of 120° in each case relative to the vertical orientation of the upper roller 20 . 1 .

[0048] 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 axis of rotation of the roller shaft extends in each case parallel to a pair of side surfaces 14.1, 14.4, 14.2, 14.5, 14.3, 14.6. Furthermore, the axis of rotation is arranged transversely to the rolling axis 19 and is arranged in a rotationally symmetrical or star-shaped manner around the axis. Figure 1A The axis of rotation of the roller shaft of the upper roller 20.1 in the upper roller is oriented in the X direction. The axes of rotation of the other two roller shafts are correspondingly inclined at an angle of 120° and 240° respectively relative to the axis of rotation of the upper roller shaft. In each case, Figure 1A Only the drive-side ends 24.1, 24.2, 24.3 are shown, which protrude outwards at one of the side surfaces 14.2, 14.4, 14.6 of the support housing 10. Thus, the roller shafts can each abut against an external drive, which can thus transmit its rolling torque via the coupling to the roller shafts and thus to the rollers 20.1 to 20.3.

[0049] The roller axles extend inside the support housing 10, wherein eccentric adjustment means (not shown) are also located for adjusting the rollers 20.1 to 20.3 via their roller axles. Figure 1AIn the XY plane of the roller 20.1 to 20.3, the spacing between the roller axes and thus between the rollers 20.1 to 20.3 on the one hand and the rolling axis 19 on the other hand can be changed. Thus, for a constant caliber 21, different sizes of the caliber 21 can be provided and the wear of the rollers 20.1 to 20.3 can also be compensated. The eccentric adjustment member forms an adjustment mechanism for the rollers 20.1 to 20.3.

[0050] The adjustment mechanism of the rollers 20.1 to 20.3 can be actuated from the outside in that the adjustment connector 30 protruding to the outside near the corner 16.1 is rotated. Figure 1A In the embodiment shown in , the adjustment connector 30 is designed so 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 support housing 10 and to a bevel gear meshing in the toothed segment of an eccentric bushing of the eccentric adjustment member, the eccentric bushing in turn being able to transmit the rotational movement transmitted to it via the bevel gear to the other two eccentric bushings and thus being able to allow a synchronous adjustment of the rollers. The adjustment mechanism is Figure 1A Not shown in detail is the adjustment connector 30 .

[0051] The adjustment connector 30 is positioned near the corner 16.1, and the gear shaft connected to the adjustment connector 30 is connected to the gear shaft. Figure 1A 1 , i.e. in the X direction, the drive-side end 24.1 of the upper roller shaft protrudes out of the support housing 10 on the opposite side. The adjustment connector 30 is therefore positioned essentially opposite the drive-side end 24.1 of the roller shaft extending parallel to the gear shaft. This relative 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 the motor coupled thereto forms a large free space therebetween, which makes the adjustment connector 30 freely accessible.

[0052] exist Figure 1A In the embodiment, the adjustment connector 30 is arranged close to the corner 16.1 and so as to be slightly offset upwards relative to the imaginary horizontal center plane of the support housing 10. In this case, along Figure 1A The Y axis in the adjustment connector 30 is between the center plane extending parallel to the gear axis (i.e., between Figure 1A The spacing in the X direction (in the X direction) is less than 10% of the extension of the support housing 10 in the Y direction (ie between the two opposite side surfaces 14.2, 14.5 of the support housing 10).

[0053] Figure 1AThree mounting elements 26.1, 26.2, 26.3 are shown for guides of the material to be rolled ( Figure 1A The guide member may be mounted on the outlet side 13 of the support housing 10. Figure 1A The mounting elements 26.1, 26.2, 26.3 can also be arranged on the inlet side 15 (at Figure 1A (not visible in the figure) so that guides for the material to be rolled can be installed there.

[0054] The guide for the material to be rolled can be, for example, a roller guide, in particular a roller guide 60, such as Figure 1B 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 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.

[0055] In addition, three coupling member clamping areas 50.1, 50.2, 50.6 are arranged on Figure 1A 1, in the adjacent corners 16.1, 16.2, 16.6 of the support housing 10. The coupling clamping areas 50.1, 50.2, 50.6 are delimited in each case by two clamping rails 52. The three adjacent corners 16.1, 16.2, 16.6 in which the coupling clamping areas 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 clamping areas 50.1, 50.2, 50.6 are used to attach the roller guide adjustment connector 64 (at Figure 1A Not shown in, but in Figure 1B 1 ) is firmly fastened to the support housing 10. This relative arrangement of the coupling clamping areas 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 around these enables a certain flexibility in the arrangement and configuration of the support 1 in combination with the roller guide and thus transfers to the entire system consisting of the support 1 and the roller guide.

[0056] Figure 1AThe display stand housing 10 comprises four slide rails 40.2, 40.3, 40.4, 40.5 on the outlet side 13, said rails being arranged parallel to the four adjacent side surfaces 14.2, 14.3, 14.4, 14.5. The slide rails 40.2 to 40.5 are adjacent to each other and extend along the periphery of the hexagonal stand housing 10 from the corner 16.2 including the coupling clamping area 50.2 to the corner 16.6 including the coupling clamping area 50.6. Figure 1A In the description of FIG. 1 , the slide rails 40.2 to 40.5 are not arranged on the side surfaces 14.2 to 14.5, but are offset inwardly in the direction of the rolling axis 19. The slide rails 40.2 to 40.5 form sliding surfaces which extend on the one hand along the side surfaces 14.2 to 14.5 in the peripheral direction and on the other hand outwardly from the paper plane parallel to the rolling axis 19 and the side surfaces 14.1 to 14.6, i.e. in the direction of the rolling axis 19. Figure 1A The slide rails 40.2 to 40.5 can thus be used as contact surfaces in four orientations of the support 1 and are particularly intended to facilitate the reception of the support 1 in a support base (not shown), since the support 1 can be pushed into the support base on the slide rails 40.2 to 40.5 and in this case the slide rails 40.2 to 40.5 can also be used as sealing elements. Figure 1A On the bracket 1 (not shown), four slide rails 40.2 to 40.5 are also positioned opposite the shown slide rails 40.2 to 40.5, so 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.

[0057] The support 1 further comprises Figure 1A The three water outlets 42.1, 42.2, 42.3 on the outlet side 13 are shown in FIG. Thus, for example, cooling water intended for the roller guide can be supplied via the water supply opening ( Figure 1A 1, 14.3, 14.5 is introduced into the support housing 10, is guided through the support housing 10 and is guided out through one of the water outlets 42.1, 42.2, 42.3 and is fed from there to the roller guide.

[0058] In addition, Figure 1A On the outlet side 13 shown in the figure and on the inlet side 15 (not shown in this figure), there are a total of five clamping points 44.2, 44.3, 44.4, 44.5, 44.6 located in the corners 16.2, 16.3, 16.4, 16.5, 16.6 of the side surface 14 along which the slide rails 40.2, 40.3, 40.4, 40.5 are arranged, and the clamping points can absorb the clamping force from the bracket base for fixing the bracket 1.

[0059] Figure 1B Display is in a position relative to Figure 1A The orientation of the support 1 is obtained by tilting the support 1 by about 180° about the horizontal axis K (ie, its extension in the X direction) from the position Figure 1A of bracket 1. Therefore, Figure 1B is based on Figure 1A 1, showing the inlet side 15. In this position of the support 1, Figure 1A The position described in is opposite, with the rollers 20.1 to 20.3 being arranged in a Y arrangement.

[0060] The roller axis is relative to the Figure 1A The positions of the support 1 are displaced in parallel and therefore their drive-side ends 24.1 to 24.3 protrude out of the support housing 10 in the same direction, but are mirrored in different positions, in particular at the respective corners 16.2, 16.4, 16.6. Therefore, due to the above-mentioned inclination, the presented support 1 allows use in rolling mills with both a Y arrangement and an inverted Y arrangement of the rollers 20.1 to 20.3 in the same support base, the drive-side ends 24.1 to 24.3 of the roller shafts being only displaced in translation. This allows a high degree of flexibility in the use of the support 1 in compact rolling mills. The rolling drives coupled to the drive-side ends 24.1 to 24.3 of the roller shafts in the two positions of the support 1 can be arranged on the same side of the rolling axis 19 for each support position with the alternating Y arrangement and the inverted Y arrangement, which makes the space requirement of the entire rolling mill relatively small.

[0061] Due to the tilting about the axis K, the adjustment connector 30 is still arranged near the corner 16.1 of the support housing 10. It is arranged in a manner slightly offset downwards relative to the horizontal center plane of the support housing 10, in particular mirrored at the corner 16.1. However, also in this position of the support 1, i.e. the Y arrangement, the adjustment connector 30 is easily accessible from the same side and is therefore particularly suitable for efficient manual operation of the support 1 adjacent to the eccentric adjustment member.

[0062] Figure 1B Further shown is a roller guide 60, which is fastened to the support housing 10 via mounting elements 26.1 to 26.3, which have been described above with reference to Figure 1A Describes and also exists in Figure 1B 15 on the inlet side 15 of the support housing 10 shown in FIG. The roller guide 60 is also adjustable in that 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 cardan shaft 62 to a roller adjustment connector 64, via which a torque can be applied to the roller adjustment mechanism.

[0063] The roller adjustment connector 64 is attached to the coupling clamping area 50.1 and the clamping rail 52 associated therewith 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 shell 10, the roller guide 60 can be firmly, accurately and quickly attached to the bracket shell 10.

[0064] In addition, the water line 66 of the roller guide 60 is 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 support 10 and when the support is received in the support base and connected to the water connection of the support base, the cooling water is supplied through the water inlet 43.3 ( Figure 1B (not shown) is fed to the bracket 10.

[0065] Figure 1C Display is relative to the Figure 1A The position of the rolling axis 19 is rotated about 120° clockwise from the position Figure 1A Due to the geometry of the support 1, the rollers 20.1 to 20.3 are oriented in the Figure 1A The same inverted Y arrangement is shown in the position shown in FIG. 1 , and the three drive side ends 24.1 to 24.3 also extend in the same direction and are located at the same position so that they can be coupled to an external motor for use with the motor from Figure 1A The rolling torque is applied in the same manner as in the position of Figure 1A In contrast, the adjustment connector 30 is arranged to be rotated approximately 120° clockwise.

[0066] This arrangement is preferably used to implement remote adjustment of the adjustment mechanism of the rollers 20.1 to 20.3 by means of an external motor. Figure 1C The positioning of the support 1 in the position shown in FIG. 1 enables the external adjustment coupling of the external adjustment motor to engage with the adjustment connector 30 in the support base (not shown) and actuate the adjustment connector 30 in order to adjust the rollers 20.1 to 20.3. Figure 1A and 1B The situation is different in the position shown in .

[0067] 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 repaired quickly. This requirement in turn means that Figures 1A to 1D Push the bracket in the middle to the right into the bracket base to drive Figure 1A and 1B Vertical roller 20.1 or Figure 1C and 1DThe rolling motors of roller 20.2 can be engaged with the corresponding drive side ends 24.1 and 24.2 respectively, because the rolling motors of roller 20.1 are arranged in Figure 1A and 1B The rolling axis 19 is arranged on the right side of the rolling axis 19, and for 20.2, it is arranged on Figure 1C and 1D The rolling axis 19 is located on the right side of the bearing so as to be coupled to the drive side ends 24.1 and 24.2 respectively.

[0068] This in turn means that in Figures 1A to 1D In the embodiment, no external adjustment motor can be positioned close to the left side of the rolling axis 19 and thus also close to the left side of the support 1, i.e. in front of the rolling axis 19 in the insertion direction. Figure 1A and 1B The position of is configured for manual adjustment, ie, actuation of the adjustment connector 30 by a person, and in this configuration, the adjustment connector 30 cannot be actuated by the automatic remote adjustment means, or can only be actuated with excessive effort. Figure 1C and 1D , in which the adjusting connector is positioned behind the rolling axis 19 in the insertion direction, is configured for remote adjustment, ie actuation of the adjusting connector 30 by means of an external motor.

[0069] exist Figure 1C In the position of the support 1 shown in FIG. 4 , 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 clamping area 50 . 6 is positioned next to the rolling axis 19 in the horizontal direction.

[0070] Figure 1D Show from Figure 1C The preferred bracket in the configuration of (i.e., the configuration with remote adjustment of the adjustment connector 30 in the upper right corner). Bracket 1 in Figure 1D The position in the middle can be adjusted by tilting the support 1 by about 180° about an axis K which is tilted by about 120° relative to the horizontal and thus also by 60°. Figure 1C The position in FIG. 1 shows that the axis extends through the corners 16.1 and 16.4. Figure 1A The position of bracket 1 is consistent with that from Figure 1B The transition between the positions of bracket 1 is also from Figure 1C The position of bracket 1 is consistent with that from Figure 1D After the transition between the positions of the bracket 1, a tilting of about 180° occurs about the axis K, which extends substantially parallel to the gear axis of the adjustment connector 30. Therefore, after this tilting, the orientation of the adjustment connector 30 does not change, and the rollers 20.1 to 20.3 are moved from Figure 1C The inverted Y arrangement shown in Figure 1Dand vice versa.

[0071] Figure 1D and Figure 1B Similarly, the inlet side 15 of the support 1 is shown. Figure 1B In FIG. 5 , a roller guide 60 comprising a cardan shaft 62 and a roller adjustment connector 64 is attached to the bracket housing 10 using a clamping rail 52 via mounting elements 26 . 1 , 26 . 2 , 26 . 3 and a coupling clamping area 50 . 2 .

[0072] exist Figure 1D In the position of the support 1 shown in FIG. 4 , the support 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 the horizontal direction.

[0073] Due to the hexagonal shape of the bracket housing 10, the bracket 1 can be arranged in Figures 1A to 1D Of the four positions shown in , said positions are all compatible with similar arrangements of rolling motors in rolling mills with a support base. Thus, both a Y arrangement and an 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 connectors 30, one for manual adjustment and one for remote adjustment. In the case of known square support housings, this flexibility is not achieved, since these are firmly seated and can only be displaced and shifted on or along one side surface of the support housing, which fixes the orientation of the adjustment connectors to a constant orientation of the rolling motor.

[0074] Figure 2A is a perspective view of the inlet side 15 of a preferred support 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 oriented horizontally to the side.

[0075] Along the exterior 12 of the bracket housing 10, recesses and bores are visible which are provided for receiving the roller axles (at Figure 2A In the drawing, only the drive-side end 24.2 of the roller axle belonging to the roller 20.2 is directly identifiable) and the adjustment connector 30. It can also be seen that the clamping point 44.6 on the inlet side 15 facing the viewer is connected to the opposite clamping point on the outlet side 13 by means of screws, so that the clamping force applied to the clamping point 44.6 can be directly and stably conducted between the clamping points 44.6 in order to fix the support 1 in its support housing without causing serious deformation or even damage to sensitive parts of the support housing 10 due to excessive local force introduction. The clamping points 44.2 to 44.5 are designed in the same way and are connected to each other.

[0076] and Figure 2A Same, Figure 2B From Figure 2A Different views show the inlet side 15 of the support 1 , wherein the drive-side ends 24 . 1 of the roller axles of the rollers 20 . 1 are visible.

[0077] Figure 3A and 3B Each is a side view of a bracket with three rollers oriented in an inverted Y arrangement. Figure 3A The corner 16.1 and the side surfaces 14.1 and 14.6 are shown as well as the adjustment connector 30 and the drive side ends 24.2 and 24.3 of the roller shafts of the rollers 20.2 and 20.3.

[0078] Figure 3A Two water inlets 43.2 are further shown, which can be connected to water connections in the support base in order to receive water in the support housing 10 and to conduct it via the water outlets 42.2, for example, in order to feed it to the water line 66 of the roller guide 60. Figure 3A In the figure, an air connection 41.2 can also be seen next to the drive side end 24.2, via which compressed air can be fed to the support housing 10 in order to protect the interior of the support housing 10 (in particular the gearbox components positioned therein, such as the eccentric adjustment member) from water infiltration by overpressure.

[0079] Figure 3B Show and from Figure 3A Corner 16.4 opposite corner 16.1, and side surfaces 14.3 and 14.4 opposite side surfaces 14.1 and 14.6. In addition, slide rails 40.3 and 40.4 on both inlet side 15 and outlet side 13 are visible. Figure 3B In the perspective view of FIG. 2 , the drive-side end 42.1 of the roller shaft of the roller 20.1 is visible at the end face, and an air connection 41.1 and two water inlets 43.3 are also shown.
