Description

Technical Field

[0001] The present invention relates to a support housing for a support for rolling metal rods, wires or tubes along a rolling axis, the support housing including a water inlet designed to conduct water through the interior of the support housing to a water outlet. Background Technology

[0002] The support housings described in the above-mentioned technical field are known in principle, for example, from CN 212 760 366U and CN 212 760 331U. To date, when viewed along the rolling axis, the support housings have generally had a rectangular shape.

[0003] 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.

[0004] Furthermore, the roundness of the material to be rolled is often insufficient after passing through a single support because, due to the arrangement of the rollers and their relatively small number, the cross-section takes on a polygonal shape, with the number of sides of the polygon 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.

[0005] 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.

[0006] Therefore, when using three-roller supports, in each case, for example, the three rollers of the first and third supports of a four-support rolling mill 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 a Y-shape and an inverted Y-shape, 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 making the cross-section of the material to be rolled round.

[0007] 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.

[0008] 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.

[0009] The bracket known from CN 212 760 366U 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 both orientations. The upper and lower surfaces of the rectangular bracket housing serve as contact surfaces in the bracket base.

[0010] For the operation of the support, the conventional method is to fasten the peripheral devices to the support. Furthermore, it has been found advantageous to allow for precise caliber setting to enable roller adjustment, since these are mounted via, for example, an eccentric mechanism and therefore their distance from the rolling axis is variable. Various adjustment options exist, the details of which are independent of the current connection. However, in the case of known supports, for different adjustment configurations, particularly remote and manual adjustment configurations, and for different peripheral devices, such as roller guides, laborious modifications to the support and the support base that receives it are required. This particularly involves the conduction of water or another cooling medium and, optionally, compressed air used to seal the support housing through the support housing. Summary of the Invention

[0011] Against this background, the object of the present invention is to provide a support housing in the above-mentioned technical field, which allows for more flexible use of the support within a rolling mill, and particularly more flexible selection of its position and configuration within the rolling mill, as well as a compact design of the rolling mill that includes water pipelines inside the support housing.

[0012] This objective is achieved by the bracket housing according to technical solution 1. Advantageous embodiments of the invention become apparent from the accompanying technical solutions.

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

[0014] This design of the support housing allows for particularly flexible use within the rolling mill. Compared to existing support housings, including those for water lines, this design makes it easier to switch between different locations within the rolling mill, between different orientations, and between different configurations.

[0015] In the context of this invention, the side surfaces are the inlet and outlet 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.

[0016] 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.

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

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

[0019] Preferably, two parallel water inlets are arranged on three non-adjacent side surfaces in each case, one of which is designed in each case to conduct water through the interior of the support housing to an outlet on the outlet side, and the other of which is designed in each case to conduct water through the interior of the support housing to an outlet on the inlet side.

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

[0021] Specifically, viewed along the rolling axis, the outlet is positioned in every case on the vertical bisector of the edge of the hexagon. This preferred positioning of the outlet on the vertical bisector is particularly preferably positioned on an extension of the roller plane (i.e., the plane of rotation) in the direction of the associated roller on the nearest edge of the hexagon. Therefore, the water supply for the roller guide can be arranged in a space-saving manner.

[0022] Furthermore, preferably, in each case, air connectors are arranged at three non-adjacent side surfaces, the air connectors being designed to conduct compressed air into the interior of the support housing. Air connectors for feeding compressed air into the support housing to seal it and prevent water from penetrating in undesirable ways (e.g., through bearings) are known in principle. Preferred embodiments of the support housing enable its efficient and flexible use in the support base of a rolling mill, without the advantage of compressed air seals that would contradict this efficient use. Therefore, a support housing is provided that is particularly flexible and reliable.

[0023] In this configuration, the three air connections advantageously lead to a common cavity, and the support housing is designed to prevent compressed air from leaking out of one of the air connections via a valve. Therefore, the three air connections can preferably be equipped with check valves, etc., to provide, on the one hand, the possibility that compressed air can be applied to the common cavity via all three air connections for sealing, and on the other hand, to avoid limiting the flexibility of the support housing in the rolling mill during the process. Regarding any escaped compression, the air connections of the air support housing that are not connected to the compressed air system in each case can be automatically closed via the corresponding check valve, or optionally manually closed manually in the case of different valves.

[0024] Advantageously, the air connector is arranged on the same non-adjacent side surface as the water inlet. This allows the corresponding connectors for water and compressed air to be arranged together closely on the side of the support base, resulting in an overall efficient design of the mill. However, the air connector can also be arranged on a side surface adjacent to the side surface of the water inlet in each case.

[0025] Preferably, in each case, one of the water inlets and one of the air connectors are oriented parallel to each other and designed to connect in the same direction. This ensures that these connections can be made particularly reliable and efficient to the corresponding connectors of the bracket base while the bracket is inserted into the bracket base, and in the same insertion direction.

[0026] The preferred support housing further includes three bearing holes for mounting the roller shaft in each case, the bearing holes being formed in one of the side surfaces so as to rotate about 120° off the rolling axis in each case, and the water inlet being introduced into those side surfaces that do not include the bearing holes.

[0027] This design of the bracket housing ensures that the water inlet does not collide with the roller shaft or the drive system on the bracket base side, and makes efficient use of the installation space in the bracket housing and bracket base.

[0028] The preferred support housing is enclosed and non-divided, and in particular, 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 the rolling process, as well as efficient manufacturing.

[0029] A preferred support 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 shape around the rolling axis, the rollers together forming a diameter; and a support housing as described above.

[0030] Other advantages and developments of the present invention will become apparent from the accompanying drawings and the following description of all technical solutions. Attached Figure Description

[0039] 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.

[0040] 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 support 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 the embodiment of the invention, 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, 14.6 positioned parallel to each other in each case. The bracket housing 10 is manufactured as a single piece.

[0041] 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.

[0042] 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 configuration because the upper roller 20.1 is vertically positioned, and the two remaining lower rollers 20.2 and 20.3 are positioned at a 120° angle relative to the vertical orientation of the upper roller 20.1 in each case.

[0043] 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.

[0044] The roller shaft extends inside the support housing 10, where an eccentric adjustment member (not shown) is also positioned for adjusting rollers 20.1 to 20.3 via its roller shaft. The eccentric adjustment member allows for... Figure 1A In the XY plane, the spacing between the roller shafts can be changed, thus altering the spacing between rollers 20.1 to 20.3 on one side and the rolling axis 19 on the other. Therefore, for a constant diameter 21, different sizes of diameter 21 can be set, and wear of rollers 20.1 to 20.3 can also be compensated. The eccentric adjustment member forms an adjustment mechanism for rollers 20.1 to 20.3.

[0045] 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.

[0046] 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.

[0047] 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).

[0048] Figure 1A Three 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.

[0049] 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.

[0050] 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.

[0051] Figure 1A The 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

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.

[0061] 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.

[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 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 1D The 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.

[0063] 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.

[0064] 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.

[0065] 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 1D The Y-shaped arrangement shown in the image is also the same as the reverse.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Recesses and drilled holes are visible along the outer 12 of the support housing 10, said recesses and drilled holes being provided for receiving roller shafts (in Figure 2A In this configuration, only the drive-side end 24.2 of the roller shaft belonging to roller 20.2 is directly identifiable, along with the adjustment connector 30. Furthermore, it is evident that the clamping point 44.6 on the viewer-facing inlet side 15 is bolted to the opposing clamping point 44.6 on the outlet side 13, allowing the clamping force applied to the clamping points 44.6 to be directly and stably transmitted between them, thus securing the bracket 1 within its bracket housing without causing severe deformation or even damage to sensitive components of the bracket housing 10 due to excessive localized forces. Clamping points 44.2 to 44.5 are designed in the same manner and connected to each other.

[0071] and Figure 2A Same, Figure 2B From and Figure 2A The inlet side 15 of the bracket 1 is shown from different perspectives, in which the drive side end 24.1 of the roller shaft of roller 20.1 is visible.

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.

[0073] 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.

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.
