Description

Technical Field

[0001] The utility model relates to a bracket shell of a bracket used for rolling metal rods, wires or pipes along a rolling axis. The bracket shell comprises a water supply port designed to conduct water through the interior of the bracket shell to a water outlet. Background Art

[0002] Support shells of the aforementioned technical field are known in principle, for example, from CN 212 760 366 U and CN 212 760 331 U. Hitherto, the support shells have generally had a rectangular shape, viewed along the rolling axis.

[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 being rolled is often insufficient after passing through a single stand, as the arrangement of the rollers and their relatively small number results in a cross-section that assumes a polygonal shape, with the number of sides corresponding to the number of rollers in the stand. For example, a material being rolled by a single three-roller stand has a cross-sectional shape that is not a perfect circle but rather a nearly triangular shape.

[0005] In order to improve the roundness of the material to be rolled, the successive 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 centres of the rollers of the next stand and thus round the cross section of the material to be rolled.

[0006] Therefore, when using three-roller stands, 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 the rollers of the subsequent stands (e.g., the second and fourth stands) are arranged in a so-called "inverted Y arrangement." Since the rollers and stands are arranged alternately in a Y arrangement and an inverted Y arrangement, the corners of the cross section of the material to be rolled are rolled by the rollers using the lower stand, and thus the cross section of the material to be rolled is rounded.

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

[0008] The arrangement of the supports one after another to form a rolling mill is usually carried out using a support base into which the supports are introduced and by which the supports are held. This makes it possible to replace the supports from the rolling mill, for example for regularly required maintenance.

[0009] The bracket known from CN 212 760 366U allows switching between a Y arrangement and an inverted Y arrangement by rotating about 180° about a horizontal axis and allows insertion into a bracket base in two orientations. The upper and lower side surfaces of the rectangular bracket housing serve as contact surfaces in the bracket base.

[0010] For the operation of the support, it is customary to fasten the peripheral devices to the support. Furthermore, it has been found advantageous to be able to adjust the rollers for precise setting of the caliber, since these are mounted, for example, via an eccentric mechanism and thus have a variable spacing from the rolling axis. Various adjustment options exist, the details of which are independent of the current connection. However, with known supports, different adjustment configurations, particularly remote and manual, as well as different peripheral devices such as roller guides, require laborious modification of the support and its receiving base, which in particular involves the conduction of water or another cooling medium, and optionally compressed air for sealing the support housing, through the support housing. Utility Model Content

[0011] Against this background, the object of the present invention is to provide a support housing according to the above-mentioned technical field, which allows a more flexible use of the support within the rolling mill and in particular a more flexible choice of both the position and the configuration in the rolling mill, as well as a simultaneously compact design of the rolling mill including the water pipeline inside the support housing.

[0012] This object is achieved by a bracket housing according to technical solution 1. Advantageous embodiments of the present invention emerge from the appended technical solutions.

[0013] A support housing for rolling metal rods, wires, or tubes along a rolling axis has an exterior with six side surfaces forming the edges of a regular hexagon when viewed from the rolling axis; an inlet side; and an outlet side. In this case, at least one water inlet is arranged on three of the non-adjacent side surfaces, the inlet being designed to conduct water through the interior of the support housing to a water outlet on the outlet side or the inlet side.

[0014] This design of the support housing makes it possible to use the support housing in a particularly flexible manner within the rolling mill. Compared to the case of support housings from the prior art that include water lines, a support housing designed in this way can be more easily switched between different positions in the rolling mill, between different orientations, and between different configurations.

[0015] In the context of the present invention, side surfaces are surfaces of the support shell that transversely delimit the inlet side and the outlet side through which the rolling axis extends. Viewed along the rolling axis, they together form the transverse outer surface of the support shell.

[0016] The side surface of the support housing can serve as a contact surface, including or extending parallel to a contact surface or multiple contact surfaces formed, for example, by a guide 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 include steps, protrusions or recesses, as well as openings, and can also be formed in multiple parts.

[0017] The water inlets at the non-adjacent side surfaces are distributed over the side surfaces so that at least every other side surface is provided with at least one water inlet. In this case, it is also possible for all side surfaces to include at least one water inlet, and for one or more of the side surfaces to include multiple water inlets. The fact that three of the non-adjacent side surfaces each include at least one water inlet reflects the symmetry of a regular hexagon and is particularly suitable for a support housing comprising three rollers.

[0018] The water outlet on the outlet side or inlet side or both serves to output water conducted into the support housing via a water supply in each case connected to the water outlet to peripheral devices, such as roller guides of rollers of the support or cooling devices.

[0019] Preferably, two parallel water supply openings are arranged on three side surfaces which are not adjacent in each case, one of the openings being designed in each case to conduct water through the interior of the support housing to a water outlet in the outlet side, and the other of the openings being designed in each case to conduct water through the interior of the support housing to a water outlet in the inlet side.

[0020] The fact that the two water inlets of the same side surface are oriented parallel to each other has the advantage that the connection of the water connection piece in the holder base, into which the holder housing is inserted, can take place with the same linear movement of both water inlets. In this case, it is preferred that one of the water inlets is positioned closer to the outlet side and the other closer to the inlet side.

[0021] Specifically, the water outlets are positioned on the perpendicular bisectors of the edges of the hexagon, viewed along the rolling axis. This preferred positioning of the water outlets on the perpendicular bisectors can particularly preferably be positioned in the direction of the associated rollers on the nearest edge of the hexagon, extending along the roller plane (i.e., the plane of rotation). This allows the water supply for the roller guide to be arranged in a space-saving manner.

[0022] Furthermore, preferably, air connections are arranged on three of the non-adjacent side surfaces, said air connections being designed to conduct compressed air to the interior of the support housing. Air connections for feeding compressed air into the support housing in order to seal the housing against undesirable water penetration (e.g., through bearings) are generally known. This preferred embodiment of the support housing enables efficient and flexible use of the support housing in the support base of a rolling mill, without the advantages of compressed air seals that would conflict with this efficient use of the support housing. Thus, a support housing is provided that is particularly flexible and reliable.

[0023] In this case, the three air connections advantageously lead to a common cavity, and the support housing is designed to prevent compressed air from escaping from one of the air connections via a valve. Therefore, the three air connections can preferably be equipped with check valves or the like, in order, on the one hand, to allow compressed air to be supplied to the common cavity via all three air connections for sealing, while, on the other hand, not restricting the flexibility of the support housing in the rolling mill. In case of escaping compression, the air connections of the air support housing that are not connected to the compressed air system can be closed automatically via corresponding check valves or, if different valves are used, manually.

[0024] Advantageously, the air connection is arranged on the same non-adjacent side surface as the water inlet. This makes it possible to arrange the corresponding connections for water and compressed air closely together on the side of the support base, resulting in an overall efficient design of the rolling mill. However, it is also possible to arrange the air connection on a side surface that is adjacent to the side surface of the water inlet in each case.

[0025] Preferably, one of the water inlets and one of the air connections are in each case oriented parallel to one another and are designed to connect in the same direction. This ensures that these connections can be connected particularly reliably and efficiently to the corresponding connection of the holder base at the same time and in the same insertion direction as the holder is inserted into the holder base.

[0026] Preferably, the support housing further comprises three bearing holes for mounting a roller axle in each case, the bearing holes being made in one of the side surfaces so as to be offset by approximately 120° around the rolling axis in each case, and the water feed openings being introduced into those side surfaces which do not comprise bearing holes.

[0027] This design of the bracket housing ensures that the water inlet does not collide with the roller shaft or its bracket base side transmission system, and efficiently uses the installation space in the bracket housing and the bracket base.

[0028] The support shell is preferably closed and non-divided and is in particular manufactured in one piece. In other words, the support shell is preferably manufactured in one piece and can therefore be manufactured, for example, by a casting method, so that advantageous mechanical properties for absorbing the loads acting during the rolling process and efficient manufacturing are possible.

[0029] A preferred stand for rolling metal rods, wires or tubes along a rolling axis comprises three rollers, each positioned on a roller shaft and arranged in a star-shaped manner around the rolling axis, said rollers together forming a calibre, and a stand housing according to the above description.

[0030] Other advantages and developments of the present invention will become apparent from the accompanying drawings and the following description of all technical solutions. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In the following description of the drawings, identical or corresponding elements are provided with identical reference numerals, and repeated description is largely avoided.

[0040] 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 here, has a regular hexagonal shape when viewed along the rolling axis 19. The exterior 12 of the stand housing 10 comprises 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 areas referred to as corners 16.1 to 16.6. In this case, the corners 16.1 to 16.6 can be labeled differently. They comprise adjacent edges between adjacent side surfaces 14.1 to 14.6 merging into one another in the corners 16.1 to 16.6, which edges can 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 distinctly 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 FIG has thus, like the support housing 10 of the embodiment of the invention, an overall 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 positioned parallel to one another. The support housing 10 is manufactured in one piece.

[0041] Preferably, the support 1 is designed so that the inlet side 15 (at Figure 1A Not shown) similar to Figure 1A 1 and 2, so that all features described below for outlet side 13 are found at the same or corresponding locations on the opposite side of bracket housing 10, as also shown below with reference to other figures.

[0042] The stand 1 further includes three rollers 20.1, 20.2, and 20.3 arranged in a star-shaped pattern around the rolling axis 19. The rollers 20.1 to 20.3 each define a plane of rotation that is angled 120° relative to one another and intersects in the rolling axis 19. The planes of rotation of the rollers 20.1 to 20.3 are each arranged 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 bore 21 between them. Bore 21 is surrounded, in particular, by a rolling surface 22 of each of the rollers 20.1 to 20.3, which is formed as a concave groove centrally along the periphery of the respective roller 20.1 to 20.3 in order to provide the material to be rolled with an outer contour that 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 in each case at an angle of 120° relative to the vertical orientation of the upper roller 20 . 1 .

[0043] The rollers 20.1 to 20.3 are each fixedly positioned on a roller shaft via which they are driven. The axis of rotation of the roller shaft extends parallel to each 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 said axis. Figure 1A The axis of rotation of the roller shaft of the upper roller 20.1 is oriented in the X direction. The axes of rotation of the other two roller shafts are respectively inclined at an angle of 120° and 240° 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, said ends protruding 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 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.

[0044] 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 rollers 20.1 to 20.3, the spacing between the roller axes and, therefore, between the rollers 20.1 to 20.3 on the one hand and the rolling axis 19 on the other hand can be varied. Thus, for a constant caliber 21, different sizes of caliber 21 can be provided, and wear of the rollers 20.1 to 20.3 can also be compensated. The eccentric adjustment element forms the adjustment mechanism for the rollers 20.1 to 20.3.

[0045] 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 FIG, 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 housing 10 of the support and connected to a bevel gear meshing in the toothed segments of the eccentric bushings 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 in Figure 1A Not shown in detail is the adjustment connector 30 .

[0046] 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 . The upper roller shafts in the bracket 10 extend parallel to each other, i.e., in the X direction, the drive-side ends 24.1 of these upper roller shafts protrude beyond the support housing 10 on the opposite side. The adjustment connector 30 is therefore positioned essentially opposite the drive-side ends 24.1 of the roller shafts extending parallel to the gear shaft. This relative arrangement implies that the adjustment connector 30 is not covered by the roller motor, which is arranged flush with the drive-side end 24.1 of one of the roller shafts, because the drive-side ends 24.2, 24.3 of the roller shafts adjacent to the adjustment connector 30 are each 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 between them, which makes the adjustment connector 30 freely accessible.

[0047] 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 bracket 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 FIG. 1 ) 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 ).

[0048] 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 (on Figure 1A (not visible in the figure) so that guides for the material to be rolled can be installed there.

[0049] The guides for the material to be rolled can be roller guides, for example, in particular roller guides 60, such as Figure 1B The mounting elements 26.1, 26.2, 26.3 are positioned in a star-shaped pattern around the rolling axis 19 and in each case lie 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 each arranged at an angular spacing of 120° around the rolling axis 19.

[0050] Furthermore, 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 serve to attach the roller guide adjustment connector 64 (at Figure 1A Not shown in , but in Figure 1B 1 and 16. The roller guide 1 is shown in FIG. 1 , which is securely 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, therefore, in the entire system consisting of the support 1 and the roller guide.

[0051] Figure 1AThe display stand housing 10 includes four slide rails 40.2, 40.3, 40.4, 40.5 on the outlet side 13, which 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 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, the slide rails 40.2 to 40.5 are not arranged on the side surfaces 14.2 to 14.5, but are offset inwards 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 in the peripheral direction along the side surfaces 14.2 to 14.5 and on the other hand outwards 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 serve as contact surfaces in four orientations of the holder 1 and are particularly intended to facilitate the reception of the holder 1 in a holder base (not shown), since the holder 1 can be pushed into the holder base on the slide rails 40.2 to 40.5 and in this case the slide rails 40.2 to 40.5 can also serve as sealing elements. Figure 1A 5 ), the 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.

[0052] 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 inlet ( 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.

[0053] 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.

[0054] Figure 1B Display is in a position relative to Figure 1A The orientation is obtained by tilting the support 1 by approximately 180° about the horizontal axis K (ie, its extension in the X direction) in the position from Figure 1A of bracket 1. Therefore, Figure 1B is based on Figure 1A Rear view of the support 1, showing the inlet side 15. In this position of the support 1, Figure 1A The position described in is reversed, with the rollers 20.1 to 20.3 being arranged in a Y arrangement.

[0055] Roller axis 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 from the support housing 10 in the same direction, but in different positions, in particular in mirror images at the respective corners 16.2, 16.4, 16.6. Consequently, due to the aforementioned tilting, the illustrated support 1 can be used in rolling mills having both a Y arrangement and an inverted Y arrangement of the rollers 20.1 to 20.3 in the same support base, with the drive-side ends 24.1 to 24.3 of the roller shafts being displaced only 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 both positions of the support 1 can be arranged on the same side of the rolling axis 19 for each support position in the alternating Y arrangement and inverted Y arrangement, which results in a relatively small space requirement for the entire rolling mill.

[0056] 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 slightly offset downward relative to the horizontal center plane of the support housing 10, in particular mirrored at the corner 16.1. However, even in this position of the support 1, i.e., in the Y arrangement, the adjustment connector 30 can be easily reached from the same side and is therefore particularly suitable for efficient manual operation of the support 1 adjacent to the eccentric adjustment member.

[0057] 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.

[0058] 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 housing 10, the roller guide 60 can be firmly, accurately and quickly attached to the bracket housing 10.

[0059] 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 fed into the support base through the water inlet 43.3 ( Figure 1B (not shown) is fed to the bracket 10.

[0060] Figure 1C Shows 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, 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 a motor from Figure 1A The rolling torque is applied in the same manner as in the position of Figure 1A In comparison, the adjustment connector 30 is arranged to be rotated approximately 120° clockwise.

[0061] 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 bracket 1 in the position shown in FIG. 1 is such that the external adjustment coupling of the external adjustment motor can engage with the adjustment connector 30 in the bracket base (not shown) and actuate said adjustment connector 30 in order to activate the rollers 20.1 to 20.3. Figure 1A and 1B The situation is different in the position shown in .

[0062] 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 right direction into the bracket base to drive Figure 1A and 1B Vertical roller 20.1 or Figure 1C and 1DThe rolling motors of rollers 20.2 can be engaged with the corresponding drive side ends 24.1 and 24.2, respectively, because the rolling motors of rollers 20.1 are arranged in Figure 1A and 1B The rolling axis 19 is on the right side, and for 20.2, it is arranged on Figure 1C and 1D On the right side next to the rolling axis 19 in order to be coupled to the drive side ends 24.1 and 24.2 respectively.

[0063] This in turn means that in Figures 1A to 1D In the embodiment, no external adjustment motor can be positioned to the left of the rolling axis 19 and thus also to the left 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.

[0064] exist Figure 1C In the position of the support 1 shown in FIG, the support is positioned on the slide rail 40 . 4 , 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.

[0065] Figure 1D Show from Figure 1C The preferred bracket in the configuration of (ie, the configuration with remote adjustment of the adjustment connector 30 in the upper right corner). 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 shown in FIG. 1 shows that the axis extends through the corners 16.1 and 16.4. Figure 1A The position of bracket 1 is the same as that from Figure 1B The transition between the positions of the bracket 1 is also from Figure 1C The position of bracket 1 is the same as 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 rotated from Figure 1C The inverted Y arrangement shown in the figure is transformed into Figure 1Dand vice versa.

[0066] Figure 1D and Figure 1B Likewise, 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 .

[0067] exist Figure 1D In the position of the support 1 shown in FIG, the support is positioned on the slide rail 40 . 3 , 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.

[0068] Due to the hexagonal shape of the bracket housing 10, the bracket 1 can be arranged Figures 1A to 1D Of the four positions shown in FIG, , all are compatible with similar arrangements of rolling motors in rolling mills having 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 terms of different orientations and arrangements of the adjustment connectors 30, one for manual adjustment and one for remote adjustment. With known square support housings, this flexibility is not achieved, as these are rigidly mounted 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.

[0069] 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.

[0070] Along the exterior 12 of the bracket housing 10 are visible recesses and bores which are provided for receiving the roller shafts (at Figure 2A (Only the drive-side end 24.2 of the roller shaft belonging to roller 20.2 is directly identifiable) and the adjustment connector 30. Furthermore, it can be seen that the clamping point 44.6 on the inlet side 15 facing the viewer is screwed to the opposing clamping point 44.6 on the outlet side 13. This allows the clamping forces applied to the clamping points 44.6 to be directly and reliably transmitted between them, securing the support 1 in its support housing without causing significant deformation or even damage to sensitive components of the support housing 10 due to the introduction of excessive local forces. The clamping points 44.2 to 44.5 are designed and connected to one another in the same manner.

[0071] and Figure 2A Same, Figure 2BFrom Figure 2A Different views show the inlet side 15 of the support 1 , wherein the drive-side ends 24 . 1 of the roller shafts of the rollers 20 . 1 are visible.

[0072] 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.

[0073] 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 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 2, 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 located therein, such as the eccentric adjustment member) from water leakage by overpressure.

[0074] 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, the slide rails 40.3 and 40.4 on both the inlet side 15 and the outlet side 13 are visible. Figure 3B In the perspective view of FIG, 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.
