Description

Technical Field

[0001] This utility model relates to a support for rolling metal rods, wires or tubes along a rolling axis. The support includes a support housing and three rollers positioned on roller shafts in each case and arranged in a star shape around the rolling axis to form a diameter together. The three roller shafts are mounted in bearing holes in the support housing by means of eccentric bushings, so that the radial distance between the rollers and the rolling axis is adjustable. Background Technology

[0002] A support consisting of three or more rollers is known in principle in the production of metal tubes, rods, or wires for rolling rod-shaped materials. In this case, the material to be rolled can be rolled to the desired diameter because the aperture is set accordingly. Conventionally, the distance between the rollers and the rolling axis is changed to set the aperture of the support. The technical solution for positioning the rollers relative to the rolling axis is an eccentric adjustment member.

[0003] For example, a bracket with an eccentric adjustment member is known from DE 100 15 340 A1. In the case of the bracket described herein, the rollers are positioned on roller shafts via rolling bearings, which are rotatably mounted in two eccentric bushings in each case. By rotating the eccentric bushings, the rollers can be radially adjusted relative to the rolling axis, allowing the bracket's diameter to be set steplessly and enabling the production of materials to be rolled with different diameters. In DE100 15 340 A1, the synchronous adjustment of all roller shafts and therefore all rollers can be achieved by driving only one eccentric bushing, the adjustment being made via an adjustment connector provided on the side surface of the bracket housing.

[0004] Typically, multiple supports are arranged continuously in a rolling mill. Therefore, the material to be rolled can be stretched specifically by the difference in the roller speeds between the individual supports, and rolled into a smaller diameter.

[0005] Furthermore, the roundness of the material to be rolled is often insufficient after passing through a single support because, due to the star-shaped arrangement of the rollers and their relatively small number, the cross-section exhibits a polygonal shape, with the number of sides corresponding to the number of rollers on the support. For example, the material to be rolled by a single three-roller support has a cross-sectional shape that is not ideally circular but rather approximately triangular.

[0006] To improve the roundness of the material to be rolled, it is preferable to arrange continuous supports such that, in each case, the corner of the cross-section of the material to be rolled, the material leaving the support, contacts the center of the roller of the next support, and thus makes the cross-section of the material to be rolled more round.

[0007] Therefore, in each case, for example, the three rollers of the first and third supports of a rolling mill with four supports are typically positioned in a so-called "Y arrangement," and in each case, the rollers of the supports arranged thereafter (e.g., the second and fourth supports) are arranged in a so-called "inverted Y arrangement" (⅄). Since the rollers and supports are arranged alternately in Y and inverted Y arrangements, in each case, the corners of the cross-section of the material to be rolled are rolled by the rollers using the supports below, thus rounding the cross-section of the material to be rolled.

[0008] In the Y-arrangement, the lower roller is oriented such that its roller shaft is horizontally positioned, meaning the diameter of the lower roller extends vertically in the viewing direction of the rolling axis. Conversely, in the inverted Y-arrangement, it is the upper roller whose roller shaft is horizontally positioned, meaning the diameter of the upper roller extends vertically in the viewing direction of the rolling axis. In both cases, the roller shafts of the other two rollers are positioned at an angle of 120° relative to the horizontal roller shaft. Of course, the arrangement relative to the horizontal is generally arbitrary, because for the effects described herein, only the relative arrangement of the rollers to the adjacent supports matters.

[0009] The supports are arranged one after another to form a rolling mill, typically using a support base into which the supports are introduced and held in place. This makes it possible to replace supports from the rolling mill, for example, for periodic maintenance.

[0010] The bracket known from DE 100 15 340 A1 allows switching between a Y arrangement and an inverted Y arrangement by rotating approximately 180° about a horizontal axis, and allows insertion into the bracket base in two orientations. The upper and lower surfaces of the rectangular bracket housing serve as contact surfaces in the bracket base.

[0011] The positions of the Y-arranged and inverted Y-arranged brackets can be selected such that when the side surface defines the side surface of the bracket horizontally, i.e., when vertically oriented, the adjusting connectors of the eccentric adjusting members provided on the side surface of the bracket housing remain on the same side. The coupling element for the force introduction of the transmission system, which has a motor and, if necessary, a gearbox for driving rollers with horizontally oriented roller shafts, is then positioned on the opposite side surface.

[0012] While the above arrangement of the adjustment connector allows for good accessibility of the adjustment connector by manual operation from this side, the adjustment connector cannot be easily operated and actuated automatically, i.e., by so-called remote adjustment, because the motor required for this may not be provided on this side in order not to obstruct access to the bracket. Utility Model Content

[0013] Against this background, the purpose of this utility model is to provide a support in the aforementioned technical field that allows for more flexible use within a rolling mill, particularly more flexible selection of both its position and adjustment configuration within the rolling mill, as well as a compact design for the rolling mill.

[0014] In other words, the goal is to develop supports in the aforementioned technical field that can be modularly arranged in the rolling mill, in different locations in the support base, and in different positions in a manner that is as universal as possible, so that the radial distance (i.e., adjustment) between the roller and the rolling axis can be adjusted in a variety of different ways and with different adjustment configurations.

[0015] This objective is achieved by the bracket according to technical solution 1. Advantageous embodiments of this utility model are revealed in the accompanying technical solutions.

[0016] A support for rolling metal rods, wires, or tubes along a rolling axis comprises: a support housing, the exterior of which, viewed along the rolling axis, includes at least six side surfaces of equal length arranged rotationally symmetrically about the rolling axis, wherein in each case two side surfaces form a pair of side surfaces positioned parallel to each other; and three rollers, in each case positioned on roller shafts and arranged in a star shape around the rolling axis and together forming a diameter, the three roller shafts being mounted in bearing bores in the support housing by means of eccentric bushings, such that the radial distance between the rollers and the rolling axis is adjustable.

[0017] In the context of this invention, the side surfaces are the surfaces through which the lateral defining rolling axis of the support housing extends. Viewed along the rolling axis, they together form the lateral outer surface of the support housing. Because the side surfaces are arranged in pairs parallel to each other and rotationally symmetrical about the rolling axis, the projection of the support housing along the rolling axis defines a polygon with at least six sides and corners.

[0018] The side surfaces of the bracket housing can serve as contact surfaces, including contact surfaces or extending parallel to one or more contact surfaces, such as those formed by slide rails, on which the bracket can be stably placed, particularly in the bracket base. The side surfaces need not be flat, but may also include steps, protrusions or recesses, and openings, and may also be formed in multiple parts.

[0019] In the context of this invention, side surfaces of equal length mean that they have the same length in the peripheral direction. In this case, instead of sharp corners, rounded corners, extended chamfers, etc., may be provided between adjacent side surfaces.

[0020] The fact that the rollers are positioned on a roller shaft in each case also implies, for example, rollers axially clamped between two axially separated roller shafts. Specifically, the rollers are arranged on the roller shaft in a rotatably fixed manner, such as a friction connection, i.e., not mounted on the roller shaft by bearings. This is also associated with the rollers being able to be driven by their roller shafts. For this purpose, each of the roller shafts can have its own drive connection and an end protruding outside the support. Then, by means of proper coupling, a motor can apply rotational force to each of the roller shafts respectively, and thus apply torque to the associated rollers. Multiple roller shafts can also be coupled together via a gearbox outside the support and driven by a common motor. Since the rolling force acting in the support in the technical field of this invention reaches several thousand tons, the rolling motor must be powerful and therefore must be large. The rolling motor and its periphery should not obstruct access to the rolling mill and support so as not to hinder the periodic replacement of the support for maintenance reasons.

[0021] Therefore, it is important for the entire rolling mill that the drive connections of the roller shafts are positioned in the same location and orientation at specific points within the mill, so that replacement supports can be connected to the roller drives as quickly and reliably as possible, and that these points and orientations do not impede access to the rolling mill, especially to the supports.

[0022] The star arrangement of the rollers around the rolling axis means that the rollers, or their planes of rotation, are arranged at a 120° angle relative to the two adjacent rollers, or their planes of rotation, in each case. This also applies to the roller shafts, whose axes intersect only in the planes of rotation of the rollers, but not in the caliper. However, within the support, each roller shaft is at a 120° angle relative to the other two roller shafts in each case.

[0023] In the context of this invention, caliber refers to the opening between three rollers through which the material to be rolled is guided and rolled during the process. It extends above the cross-sectional surface, orthogonal to the rolling axis of the channel formed within the rolling surface by the star arrangement of the three rollers. The caliber is not the same as the target or production diameter of the material to be rolled because the supports widen due to the material and do not elastically deform during rolling, and because the diameter of the material is affected not only by the rollers themselves but also by the elastic and plastic forces between adjacent supports. However, the caliber significantly affects the production diameter.

[0024] In the case of the bracket of this utility model, the distance between the roller and the rolling axis can be set by rotating the eccentric bushing (i.e., eccentric adjustment known, for example, from DE 100 15 340 A1) to set the diameter.

[0025] Compared to existing rectangular support housings with four side surfaces, the number and arrangement of the side surfaces of the support in this invention offer the following advantages: the support can be used in a modular manner at different locations within the rolling mill, and can be used in different configurations with respect to the adjustability of the radial distance between the rollers and the rolling axis. Therefore, the number of supports required for use by the rolling mill operator is reduced, because even after modifications to the adjustability of the radial distance between the rollers and the rolling axis, the same support can still be used universally throughout the rolling mill. Thus, this invention enables more flexible use within the rolling mill, and particularly allows for more flexible selection of both its position and adjustment configuration within the rolling mill, especially in the case of a compact rolling mill design.

[0026] This invention also allows for the flexible attachment of additional components arranged on or within the support housing. Besides the connection of the eccentric adjustment member, such components can be, for example, operating connectors, guides (e.g., funnel guides or roller guides, serving as inlet or outlet guides), sliding elements, bearing elements, and fastening elements. However, it is also in this respect that this invention allows for a very significant modularity of the rolling mill.

[0027] The limitation on the complexity of the roller arrangement is advantageous to the extent that the arrangement of the drive unit for the roller shafts within the rolling mill is thus simplified. Specifically, three different arrangements of the support are generated, which, viewed from the rolling axis, always produce three identical angles for the rotation axis of the roller shaft. When using structurally essentially identical rollers and roller shafts that can be driven by any provided drive unit, only translational displacement, such as that of the drive unit or gearbox and coupling assembly, is required to compensate for the translational offset of the roller shaft. This reduces the complexity of the rolling mill and the amount of design work required.

[0028] Preferably, viewed from the rolling axis, at least one of the side surfaces is oriented at a 120° angle relative to each of the side surfaces. In this case, the angle should be understood as an interior angle, i.e., the corner where the side surface in question defines the support housing, the corner having a total span of 120°. To move from a direction along one side surface to a direction along another side surface, a 60° change of direction in the peripheral direction is required. This allows the support to be stably positioned in at least six different locations, each tilted 60° relative to each other, on or parallel to one of the side surfaces. The preferred angle between the side surfaces, combined with the fact that the support includes exactly three rollers, results in a particularly advantageous effect: the orientation of the rollers can always be switched between a Y-oriented orientation and an inverted Y-oriented orientation, or corresponding orientations that compensate for each other in each case. This contributes to achieving particularly good quality of the rolled product in terms of its roundness.

[0029] The advantage is that the support housing can be accommodated and used in a wide variety of available locations using the same support base geometry. Therefore, the support can be flexibly arranged and used in the same support base used for all supports. At the same time, this ensures the high quality of the material to be rolled.

[0030] Preferably, each of the three roller shafts extends parallel to one of the pairs of mutually parallel side surfaces in each case. In other words, each roller has a plane of rotation arranged orthogonally to the pair of side surfaces. Preferably, in the sense of a perpendicular bisector, the plane of rotation orthogonal to the pair of side surfaces is positioned at the center along the length of the side surfaces in the peripheral direction.

[0031] This preferred feature further contributes to improving the flexibility and modularity of the supports in the rolling mill. Supports designed in this manner allow for particularly space-saving and stable arrangement of at least one of the motors used to drive the rollers via a horizontal drive shaft, when the support is positioned on or parallel to one of its side surfaces.

[0032] For example, in the case of a bracket base that supports the bracket according to the present invention such that a pair of side surfaces are horizontally oriented, six different arrangements of the bracket are possible in principle, in which the rollers are positioned in a Y-arrangement or an inverted Y-arrangement, and one roller has a horizontal roller axis, i.e., a vertical plane of rotation.

[0033] The exterior of the support housing preferably has exactly six side surfaces forming a regular hexagon. This particularly preferred embodiment of the support housing allows for its use in a particularly flexible manner. The symmetry of the support housing associated with the regular hexagon is particularly suitable for a star arrangement of the three rollers and roller shafts. Therefore, the three rollers and roller shafts within the support housing can be arranged in a particularly symmetrical manner within the support housing, thus allowing the support to be assembled into the support base in multiple different orientations, and the rollers can be coupled to the mill motor in each of these orientations.

[0034] The support preferably further includes an adjustment connector for introducing adjustment torque to adjust the radial position of the roller shaft relative to the rolling axis for setting the caliper. In this case, at least two adjustment configurations are possible: remote adjustment via an external motor and manual adjustment. For this, the external motor or a suitable tool (e.g., a wrench) must be engaged with the adjustment connector to actuate it, causing it to rotate. For example, rotational movement can be transmitted via a gearbox to one of the eccentric bushings of the support. Rotational movement can be transmitted from said eccentric bushing to other eccentric bushings of the roller shaft in a manner known in principle. Thus, all roller shafts can be adjusted synchronously via a single adjustment connector, and the caliper can be set accordingly.

[0035] The adjusting connector is preferably located on the outside of the support housing, specifically, on the lateral exterior, at the corner of the regular hexagon. In this connector, "at the corner of the regular hexagon" means that the adjusting connector is configured closer to the corner than the center of the side surface, i.e., closer to the transition between two adjacent side surfaces. This arrangement of the adjusting connector allows for greater flexibility in the use of the support. Therefore, the support can rotate approximately 180° about an axis extending through the corner and the rolling axis, thereby switching between a Y arrangement and an inverted Y arrangement without substantially changing the position of the adjusting connector.

[0036] Therefore, there are multiple positions where the bracket can be introduced into the bracket base, the orientation of the roller shaft drive coupling remains the same in all these positions, and the position of the roller shaft drive coupling is only slightly offset. This allows for flexible switching between various adjustment configurations, such as positions where the adjustment connector is easily accessible from the front for manual actuation of the bracket, and where, for example, an external motor can engage with the adjustment connector without thereby obstructing or hindering one or more other positions accessible from the front.

[0037] The adjustment connector is preferably both manually actuated and automatically actuated by an external motor. In this case, "manually actuated" means that the adjustment connector in this connection can be manually actuated by an operator using suitable tools. Conversely, "automatically actuated by an external motor" means that the adjustment connector can be actuated without manual operation and tool assistance, for example, by rotation using a suitable coupling connected to the motor. This means that the adjustment connector must be arranged and designed to be compatible with both configurations of the drive used for roller adjustment. Therefore, the bracket can be used directly in both configurations without modifying the adjustment connector for one or the other configuration, i.e., manual adjustment or automatic adjustment by means of a motor. However, the adjustment connector can also be designed for automatic adjustment only or manual adjustment only. In this case, modifications to the adjustment connector will still be required to change the adjustment configuration, although this means increased complexity compared to the preferred embodiment, but it does not substantially compromise the overall high flexibility of the bracket.

[0038] Preferably, the support housing is enclosed and non-divided, and particularly manufactured as a single piece. In other words, the support housing is preferably manufactured as a single unit, and therefore can be manufactured, for example, by casting, thus enabling advantageous mechanical properties for absorbing the loads acting during rolling, as well as efficient manufacturing.

[0039] Preferably, each of the three roller shafts or rollers can be driven independently by its own associated motor. Thus, for example, three relatively small motors can be used, as they only need to apply one-third of the rolling torque. This allows for a smaller motor design, which significantly reduces the overall size of the rolling mill.

[0040] In this configuration, each of the three roller shafts preferably includes a drive end for individual driving, the drive end protruding outward at one of the side surfaces of the support housing. This ensures that the roller shafts are driven via the side surfaces, preventing the corners of the support housing from being occupied by the drive ends of the roller shafts.

[0041] Other advantages and developments of this invention will become apparent from the accompanying drawings and the following description of all technical solutions. Attached Figure Description

[0050] In the following description of the accompanying drawings, the same or corresponding elements have the same reference numerals, and repetition of description is largely avoided.

[0051] Figure 1AThis is a view along a rolling axis 19 extending in the Z direction of a preferred support 1 for rolling metal rods, wires, or tubes. The support 1 includes a support housing 10, which, in the embodiment shown herein, is hexagonal in shape when viewed along the rolling axis 19. The exterior 12 of the support housing 10 has six side surfaces 14.1 to 14.6 of equal length, arranged in a rotationally symmetrical manner around the rolling axis 19. Adjacent side surfaces 14.1 to 14.6 merge with each other in areas referred to as corners 16.1 to 16.6. In this case, corners 16.1 to 16.6 may be designated differently. They include adjacent edges between adjacent side surfaces 14.1 to 14.6 that merge with each other in corners 16.1 to 16.6, said edges may be sharp, but are preferably chamfered or rounded. The small intermediate surface between adjacent side surfaces 14.1 and 14.6 is also possible in the sense of a significantly wider chamfer, and is still understood in the context of this invention as corner 16.1 to 16.6. The entrance side 15 of the bracket housing 10 (in...) Figure 1A Not shown in the text, but Figure 1B (shown in China) and Figure 1A The outlet side 13 shown in the figure, like the bracket housing 10 of this embodiment, generally has a regular hexagonal shape, characterized in particular by having three pairs of side surfaces 14.1, 14.4, 14.2, 14.5, 14.3, and 14.6 positioned parallel to each other in each case. The bracket housing 10 is manufactured as a single piece.

[0052] The preferred bracket 1 is designed such that the inlet side 15 (in) Figure 1A (Not shown in the text) Similar to Figure 1A The outlet side 13 shown in the figure makes all the features described below for the outlet side 13 available at the same or corresponding locations on the opposite side of the bracket housing 10, as shown in other figures below.

[0053] The support 1 further includes three rollers 20.1, 20.2, and 20.3 arranged in a star shape around the rolling axis 19. Rollers 20.1 to 20.3 define a plane of rotation in each case, the planes being at a 120° angle to each other and intersecting in the rolling axis 19. The planes of rotation of rollers 20.1 to 20.3 are arranged orthogonally to a pair of side surfaces 14.1 to 14.6 of the support housing 10 in each case. In the region of the rolling axis 19, rollers 20.1 to 20.3 form a bore 21 therebetween. The bore 21 is specifically surrounded by the rolling surface 22 of each of rollers 20.1 to 20.3, the rolling surface 22 of which is centered along the periphery of the respective roller 20.1 to 20.3 and is formed as an inwardly recessed groove to provide the material to be rolled with the most rounded possible outer profile. However, depending on the material to be rolled, the rolling surface 22 can also be designed differently, particularly as a flat surface or a convex surface. Figure 1A As can be seen, rollers 20.1 to 20.3 are arranged in an inverted Y arrangement 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.

[0054] 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.

[0055] 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 1AIn 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.

[0056] 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.

[0057] The adjusting connector 30 is positioned near corner 16.1, and the gear shaft connected to the adjusting connector 30 is... Figure 1A The upper roller shaft extends parallel to the gear shaft, i.e., in the X direction, the drive-side end 24.1 of the upper roller shaft protrudes beyond the support housing 10 on the opposite side. The adjusting connector 30 is therefore substantially positioned opposite the drive-side end 24.1 of the roller shaft extending parallel to the gear shaft. This opposing arrangement implies that the adjusting connector 30 is not covered by the roller motor 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 adjusting connector 30 are oriented approximately 60° upward and downward relative to the adjusting connector 30 and its gear shaft in each case, creating a large free space between them for the coupled motor, allowing the adjusting connector 30 to be freely accessed.

[0058] exist Figure 1A In this case, the connector 30 is positioned closer to corner 16.1 and offset slightly upwards relative to the imaginary horizontal center plane of the bracket housing 10. Figure 1A The Y-axis is located between the adjusting connector 30 and the center plane extending parallel to the gear shaft (i.e., in...). Figure 1A The spacing in the X direction is less than 10% of the extension of the bracket housing 10 in the Y direction (i.e., between the two opposite side surfaces 14.2 and 14.5 of the bracket housing 10).

[0059] Figure 1AThree mounting elements 26.1, 26.2, and 26.3 are shown as guides for the material to be rolled. Figure 1A (Not shown in the image). The guide can be mounted on the outlet side 13 of the bracket housing 10, where... Figure 1A As shown in the image. Mounting components 26.1, 26.2, and 26.3 can also be arranged on the entrance side 15 (in...). Figure 1A (Not visible in the center), allowing guides for the material to be rolled to be installed there.

[0060] The guide for the material to be rolled can be, for example, a roller guide, particularly roller guide 60, such as... Figure 1B The example shown may be a funnel guide. Mounting elements 26.1, 26.2, and 26.3 are positioned in a star configuration around the rolling axis 19, and in each case, are opposite one of the rollers 20.1, 20.2, and 20.3 relative to the rolling axis 19. The three mounting elements 26.1, 26.2, and 26.3 are arranged at 120° angular intervals around the rolling axis 19 in each case.

[0061] In addition, the three coupling clamping areas 50.1, 50.2, and 50.6 are arranged in... Figure 1A On the outlet side 13 of the bracket housing 10 shown, in the adjacent corners 16.1, 16.2, 16.6 of the bracket housing 10. The coupling clamping areas 50.1, 50.2, 50.6 are each demarcated by two clamping rails 52. The three adjacent corners 16.1, 16.2, 16.6 where the coupling clamping areas 50.1, 50.2, 50.6 are arranged are the corner 16.1 where the adjusting connector 30 is also arranged, and the two adjacent corners 16.2, 16.6 therewith. The coupling clamping areas 50.1, 50.2, 50.6 are used to hold the roller guide adjusting connector 64 (in... Figure 1A Not shown in the text, but Figure 1B (As shown in the image) It is securely fastened to the bracket housing 10. The relative arrangement of the coupling clamping areas 50.1, 50.2, 50.6 in the corner 16.1 of the adjusting connector 30 and in the two corners 16.2, 16.6 surrounding these allows for a particular flexibility in the arrangement and configuration of the bracket 1 in combination with the roller guide, and thus in the overall system consisting of the bracket 1 and the roller guide.

[0062] Figure 1AThe display bracket housing 10 includes four slide rails 40.2, 40.3, 40.4, and 40.5 on the outlet side 13, said rails being arranged parallel to four adjacent side surfaces 14.2, 14.3, 14.4, and 14.5. Slide rails 40.2 to 40.5 are adjacent to each other and extend along the periphery of the hexagonal bracket housing 10 from corner 16.2, including the coupling clamping region 50.2, to corner 16.6, including the coupling clamping region 50.6. Figure 1A In the description, slide rails 40.2 to 40.5 are not arranged on side surfaces 14.2 to 14.5, but are offset inward in the direction of the rolling axis 19. Slide rails 40.2 to 40.5 form a sliding surface that extends outward in the peripheral direction along side surfaces 14.2 to 14.5 on one hand, and outward from the paper plane parallel to the rolling axis 19 and side surfaces 14.1 to 14.6 on the other hand. Figure 1A Extending in the Z direction. Therefore, slide rails 40.2 to 40.5 can serve as contact surfaces in four orientations of the bracket 1, and are particularly designed to facilitate reception of the bracket 1 in the bracket base (not shown), as the bracket 1 can be pushed into the bracket base on slide rails 40.2 to 40.5, and in this case, slide rails 40.2 to 40.5 can also serve as sealing elements. On the opposite inlet side 15 ( Figure 1A On the (not shown) side, four slide rails 40.2 to 40.5 are also positioned opposite to the slide rails 40.2 to 40.5 shown, such that in each case, a pair of slide rails 40.2 to 40.5 on opposite sides can be used to stably mount the bracket 1 in the bracket base.

[0063] 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.

[0064] In addition, Figure 1A 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.

[0065] Figure 1B 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 1A The support 1. Therefore. Figure 1B 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.

[0066] Roller shaft relative to from Figure 1A 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.

[0067] 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.

[0068] Figure 1B 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 1A 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.

[0069] 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.

[0070] 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 1B (Not shown in the image) is fed to the support 10.

[0071] Figure 1C 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, with Figure 1A In contrast, the adjusting connector 30 is arranged to rotate approximately 120° clockwise.

[0072] This arrangement is preferably used for remote adjustment of the adjustment mechanism of rollers 20.1 to 20.3 via an external motor. The adjustment connector 30 is located in... Figure 1C The positioning of bracket 1 shown in the diagram allows the external adjustment coupling of the external adjustment motor to engage with adjustment connector 30 in the bracket base (not shown), and actuates said adjustment connector 30 to activate rollers 20.1 to 20.3. This is consistent with... Figure 1A and 1B The situation differs depending on the location shown in the text.

[0073] 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 allow for quick maintenance. This requirement, in turn, means that it is necessary to... Figures 1A to 1D The bracket in the middle is pushed into the bracket base to the right to enable drive. Figure 1A and 1B Vertical rollers 20.1 or Figure 1C and 1DThe rolling motor of roller 20.2 can mesh with the corresponding drive ends 24.1 and 24.2 respectively, because the rolling motor of roller 20.1 is arranged in... Figure 1A and 1B On the right side next to the rolling axis 19, and for 20.2, arranged in Figure 1C and 1D The right side next to the rolling axis 19 in the middle, so as to be coupled to the drive side ends 24.1 and 24.2 respectively.

[0074] This then means that, in Figures 1A to 1D In this configuration, no external adjustment motor can be positioned on the left side near the rolling axis 19, and therefore also near the left side of the support 1, i.e., in front of the rolling axis 19 in the insertion direction. Therefore, from Figure 1A and 1B The position is configured for manual adjustment, meaning the connector 30 is adjusted by human actuation. In this configuration, the connector 30 cannot be actuated by an automatic remote adjustment component, or can only be actuated by excessive effort. Figure 1C and 1D The position of the adjustment connector is located behind the rolling axis 19 in the insertion direction and is configured for remote adjustment, i.e., by means of an external motor to actuate the adjustment connector 30.

[0075] exist Figure 1C In the position of the bracket 1 shown in the figure, the bracket is positioned on the slide rail 40.4, and the roller 20.2 is a roller with a vertical plane of rotation, and the coupling clamping area 50.6 is positioned in the horizontal direction next to the rolling axis 19.

[0076] Figure 1D Showing from Figure 1C The preferred bracket in the configuration (i.e., the remote adjustment configuration with the adjustment connector 30 in the upper right corner). Bracket 1 in Figure 1D The position can be achieved by tilting the support 1 about 180° relative to the horizontal about an axis K that is tilted about 120° relative to the horizontal and therefore also tilted by 60°. Figure 1C The position is shown in the diagram, with the axis extending through corners 16.1 and 16.4. Similar to [the previous sentence, likely referring to a different location]. Figure 1A The position of bracket 1 and from Figure 1B The change in position between the supports 1 also comes from Figure 1C The position of bracket 1 and from Figure 1D After the position of bracket 1 changes, a tilt of approximately 180° occurs about axis K, which extends substantially parallel to the gear shaft of adjusting connector 30. Therefore, after this tilt, the orientation of adjusting connector 30 remains unchanged, and rollers 20.1 to 20.3 move from... Figure 1C The inverted Y arrangement shown in the middle is transformed into Figure 1DThe Y-shaped arrangement shown in the image is also the same as the reverse.

[0077] Figure 1D and Figure 1B Similarly, the entrance side 15 of display stand 1. Also, as in... Figure 1B In the bracket housing 10, the roller guide 60, which includes the universal joint 62 and the roller adjustment connector 64, is attached to the bracket housing 10 via the clamping rail 52 through the mounting elements 26.1, 26.2, 26.3 and the coupling clamping area 50.2.

[0078] exist Figure 1D In the position of the bracket 1 shown in the figure, the bracket is positioned on the slide rail 40.3, and the roller 20.3 is a roller with a vertical plane of rotation, and the coupling clamping area 50.2 is positioned in the horizontal direction next to the rolling axis 19.

[0079] 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, all are compatible with a similar arrangement of the rolling motor in a rolling mill with a support base. Therefore, both Y-arrangements and inverted Y-arrangements of the rollers can be presented, and similarly, two different configurations in the sense of different orientations and arrangements of the adjustment connector 30, one for manual adjustment and one for remote adjustment. This flexibility is not achieved with the known square support housing, because these are firmly mounted and can only be moved and displaced on or along one side surface of the support housing, which fixes the orientation of the adjustment connector to the constant orientation of the rolling motor.

[0080] 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.

[0081] 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.

[0082] and Figure 2A Same, Figure 2B From and Figure 2A The entry 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.

[0083] 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.

[0084] 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 3A 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.

[0085] Figure 3B Showcase and from Figure 3A Corner 16.1 opposite corner 16.4, and side surfaces 14.3 and 14.4 opposite side surfaces 14.1 and 14.6. Furthermore, slide rails 40.3 and 40.4 are visible on both the inlet side 15 and the outlet side 13. Figure 3B In the perspective view, the drive side end 42.1 of the roller shaft of roller 20.1 is visible at the end face, and an air connector 41.1 and two water inlets 43.3 are also shown.
