Description

Technical Field

[0001] The utility model relates to a support base for a rolling mill, which comprises two or more supports arranged one behind the other in the rolling direction of a material to be rolled. Background Art

[0002] Rolling mills in the aforementioned technical field have been known in principle for decades. Round products are usually produced in such rolling mills, which continuously pass through a number of stands in order to be gradually adjusted from the starting product to the desired shape and size of the semi-finished or finished product.

[0003] In this context, it has been customary to design a rolling mill for a predetermined number of stands arranged one behind the other. Each rolling mill typically has four stands, which are always designed in pairs so that the rolls of a stand contact the material at points where the previous stand did not. In this context, in the case of three-roll stands, reference is made to Y and reverse Y arrangements, which always alternate with each other.

[0004] The rolling mill can receive all the stands together. DE 10 2016 217 202 B4 discloses a rolling mill for rolling rod-shaped or tubular products, comprising two or more stands arranged one behind the other in the rolling direction of the material to be rolled. The rolling mill includes at least one measuring device arranged in the rolling direction in front of, between, or behind the stands, in order to control or regulate the rolling speed in at least one of the stands based on this measurement device.

[0005] A disadvantage of the rolling mills known from the prior art is that they can only accommodate all the stands in their entirety and are therefore not flexibly adaptable to different requirements.

[0006] A disadvantage of the method of determining the forces acting between the stands and the forces acting on the rolling mill from the outside (eg due to a roughing or intermediate rolling mill) is that the common stand clamping has an influence on the measurement signal, which is thereby falsified. Utility Model Content

[0007] Against this background, the object of the invention is to develop a rolling mill from the prior art such that the rolling mill can be adapted more flexibly to different requirements with regard to the number and arrangement of the stands received in the rolling mill.

[0008] According to a first aspect, a support base for a rolling mill having two or more supports arranged one behind the other in the rolling direction of the material to be rolled, the support base comprising two or more receiving modules arranged one behind the other, the two or more receiving modules being fastened to a common lower base frame and a common upper cover frame.

[0009] The support base is therefore designed in a modular manner, comprising a plurality of receiving modules that can each receive a single support. In this case, the receiving modules of the support base are distinguished from the individual support bases outside the rolling mill assembly. In accordance with the present invention, the receiving modules are part of the support base of the rolling mill.

[0010] In this sense, the receiving module according to this first aspect is fastened to a common lower base frame and a common upper cover frame. The base frame and the cover frame absorb the forces acting on the brackets received in the receiving module during operation and thus prevent these forces from being directly introduced into the base. This ensures a high stability of the bracket base and, consequently, a high degree of precision in the relative positioning of the brackets in the receiving module relative to one another. In this case, the base frame and the cover frame preferably extend over the entire extent of the rolling mill in the rolling direction, but may also cover only a smaller length, so that the rolling mill may include a plurality of such base frames and cover frames.

[0011] The receiving modules make it possible to receive individual supports in individual receiving modules and thus to use the rolling mill in a flexible manner. Furthermore, due to the modular design that the receiving modules can achieve, the rolling mill can be produced and designed in a more cost-effective manner.

[0012] According to a preferred embodiment, a support base for a rolling mill having two or more supports arranged one behind the other in the rolling direction of the material to be rolled comprises two or more receiving modules individually mounted in the base, each of the supports comprising more than four side surfaces that together form the periphery of the support, as viewed in the rolling direction, and each of the receiving modules being designed to receive one of the supports through a lateral opening such that the receiving module covers four of the side surfaces and more than half of the periphery of the support. In this preferred embodiment, the support base comprises protective flaps located between all the receiving modules arranged adjacently one behind the other on the sides of the lateral openings in order to protect the intermediate space between adjacent receiving modules from the escape of rods or water and to prevent persons from reaching the intermediate space.

[0013] The fact that the opening is lateral is related to the rolling direction. The receiving modules are therefore positioned one behind the other, viewed in the rolling direction, and can each receive a support transversely to the rolling direction. In this case, when a support is replaced for maintenance or by a support with a different calibration, for example, the support is always received from the same side of the receiving module.

[0014] To allow the rack to be inserted laterally into the receiving module, the receiving module at least sometimes includes an opening on the side. The rack base can also be accessed from this side to facilitate rack replacement. This also means that as many racks as possible can be accessed from this side of the rack base.

[0015] The receiving modules are designed to receive supports having more than four side surfaces in each case. The supports preferably each comprise six side surfaces and, viewed in the rolling direction, the outer shape of the supports forms a regular hexagon. Alternatively, the receiving modules can also be designed to receive supports having four side surfaces in each case. In order to securely receive the supports, the receiving modules have a shape that is adapted to the shape of the supports. This means that the shape of the receiving modules is essentially the negative form of the outer shape of the part of the supports received by the receiving modules. The fact that each of the receiving modules is designed to cover four of the preferably six side surfaces of the supports means in particular that the receiving modules comprise surfaces to which some side surfaces of the supports are partially adjacent or which are surrounded by some side surfaces, so that the supports are securely and firmly mounted in the receiving modules. For this purpose, further structural measures can also be taken, in particular clamping blocks, strips or anchors. For supports having four side surfaces, the receiving modules can be designed to cover three of the side surfaces of the supports.

[0016] In the case of a modular design of a support base with multiple receiving modules, it is therefore possible to ensure that the intermediate spaces between the receiving modules are protected. This is because, during operation of a rolling mill, large amounts of rolled material (typically steel) are guided through the mill at high speeds and temperatures. Consequently, during rolling, a condition known as a jam can occur, in which the rolled material is not properly received by the supports and flows back in front of them. If the rolling mill is not secured, the rolled material could escape rapidly and uncontrollably from the mill, which is of course unacceptable, for example with regard to occupational safety. Furthermore, large amounts of cooling water escape into the surrounding environment between the rolling mill supports, which should also be avoided.

[0017] For this purpose, the protective flap or flaps are arranged on the sides of the lateral openings of at least two of the receiving modules and cover the intermediate space. As an alternative to the preferred protective flaps, the intermediate space can also be protected by a fixed cover, or the support base can be completely protected behind a protective cover.

[0018] Preferably, each of the receiving modules includes an operating substance connection facing the lateral opening to enable the supply of operating substances to the supports. For example, the operating substance is water, in particular cooling water for the rollers, optionally for the rollers of the roller guides or the material to be rolled, and, in particular, compressed gas for sealing the supports. Each of the receiving modules may also preferably include multiple operating substance connections. If each of the receiving modules includes one or more operating substance connections, it is particularly easy to insert supports into the rolling mill in a modular manner, where the substances supplied by the operating substance are necessary or advantageous for the operation of the supports. In this way, for example, a unified connection for each receiving module can be designed so that all supports fit into all receiving modules and can be connected to the operating substance connection there. The operating substance connection is advantageously aligned with the lateral opening, meaning that it points in the direction of the lateral opening and is easily accessible from this direction. In this case, the operating substance connection is preferably designed so that a correspondingly designed support can be directly connected to one or more of the operating substance connections by being pushed into the receiving module. This can be achieved, for example, by means of a laterally open connection socket into which a corresponding connector on the holder can be pushed when the holder is pushed into the receiving module. However, such an operating material connection is not necessary.

[0019] Advantageously, each of the receiving modules includes a holder for an electrical or hydraulic remote adjustment mechanism for the support. The support received in the receiving module may include adjustable rollers. Adjustable rollers, and in particular mechanisms for adjusting rollers, are already known in principle. Automatic roller adjustment using remote adjustment mechanisms is also known. An alternative adjustment is manual adjustment of the rollers using a hand tool. For the remote adjustment mechanism, an electrically, hydraulically, or otherwise driven shaft is provided, which applies the adjustment torque to a corresponding adjustment mechanism of the support via a coupling.

[0020] According to the preferred features described above, each receiving module is provided with a holder for the remote adjustment member of the roller of the support. In particular, the holder can be, for example, a bearing for an adjustment shaft or a coupling, so that the adjustment shaft or coupling remains in the correct position for interacting with the support pushed into the receiving module. For this purpose, the support can include a coupling that can be coupled to the coupling of the remote adjustment member of the support. In a preferred embodiment, the holder for the remote adjustment member of the support makes it possible to provide or not provide a remote adjustment member, depending on the design of the support housing. In this respect, the presence of the holder does not depend on the design of the support, but allows a particularly versatile use of different supports for the support base with and without remote adjustment members. However, the holder can also be omitted.

[0021] Advantageously, each of the receiving modules includes a holder for an electrical or hydraulic remote adjustment mechanism for a roller guide attached to the support. Similar to the adjustable rollers of the support, the rollers of the roller guide attached to the support can also be adjustable. Adjustable rollers similar to these are already known in principle. Automatic roller adjustment using remote adjustment mechanisms is also known. Alternative roller adjustment methods include manual adjustment of the rollers using a hand tool or a roller holder preloaded by spring force, so that the rollers are not externally adjustable. For the remote adjustment mechanism of the roller guide, an electrically, hydraulically, or otherwise driven shaft is provided, which applies the adjustment torque to the corresponding adjustment mechanism of the roller guide via a coupling.

[0022] According to the preferred features described above, each receiving module is provided with a holder for a remote adjustment member for the roller guide. Specifically, the holder can be, for example, a bearing for an adjustment shaft or a coupling, which keeps the adjustment shaft or coupling in the correct position for interaction with the roller guide of the support pushed into the receiving module. For this purpose, the roller guide can include a coupling that can be connected to the coupling of the remote adjustment member. In a preferred embodiment, the holder for the remote adjustment member for the roller guide makes it possible to provide or not provide a remote adjustment member, depending on the design of the support housing. In this respect, the presence of the holder is independent of the design of the support and its roller guide, but allows for a particularly versatile use of the support base. However, such a holder can also be omitted.

[0023] Preferably, each bracket is securely received in a receiving module in which it is received, by means of a clamp or in another manner, so that forces acting on the bracket, in particular forces acting on the material to be rolled, are transmitted to the receiving module. The bracket is removably received in the receiving module so that the socket, in particular the clamping element, can be released, and thus the bracket, in order to replace the bracket. The secure receiving element secures the bracket in its receiving module.

[0024] Thus, the forces acting on the supports can be released and measured independently of the forces acting on the other supports, so that an improved control or regulation of the rolling process is possible.

[0025] Preferably, each of the receiving modules is mounted at the bottom in the base such that it can be tilted in the rolling direction, each of the receiving modules resting against its own counter-bearing. Particularly preferably, if each of the receiving modules is mounted in the base by means of a base frame, each receiving module is mounted on the base frame in a torque-free manner such that it can be tilted in the rolling direction.

[0026] If the receiving module is, for example, mounted in an articulated manner, it is mounted in a torque-free manner. For this purpose, the receiving module can be positioned on the joint, but an arrangement on an edge, etc., which allows tilting in the rolling direction, is also possible. For a torque-free mounting, it is important that the mounting of the receiving module in the base or on the base frame does not counteract the tilting movement of the receiving module with any significant torque, i.e., no significant force is required to tilt the receiving module in the rolling direction.

[0027] The fact that the receiving module can be tilted in the rolling direction means that it can be tilted about an axis extending perpendicular to the rolling direction and preferably extending horizontally. The axis about which the receiving module can be tilted due to the torque-free mounting is preferably arranged off-center relative to the receiving module. Further preferably, the axis is offset downstream from the center of the receiving module in the rolling direction. If, as explained above, the receiving module is mounted at the bottom in a torque-free manner, a counter-bearing at the top creates a stable arrangement. In the case of an off-center arrangement of the receiving module about its axis about which it can be tilted downwards in a torque-free manner, the receiving module rests against the counter-bearing at the top due to the tilting moment of the receiving module caused by gravity.

[0028] The torque-free mounting of the receiving module allows it to be tilted independently of the other receiving modules of the support base. The forces acting on the support in the rolling direction via the counter-bearing can be determined without changing the position of the receiving module during the process. This enables more precise handling of the material to be rolled. However, the receiving module can also be fixedly mounted in the base, in particular in the base frame, or be displaceable. Alternatively, the receiving module can be mounted in a torque-free manner at the top, allowing it to be tilted in the rolling direction and resting against the counter-bearing at the bottom.

[0029] Preferably, a force measuring device is arranged between the receiving module and the counter bearing so that the forces acting on the supports received in the receiving module in the rolling direction can be measured. For example, the device listed in DE 10 2016 217 202 B4 can be used as a force measuring device, that is, in particular a piezoelectric measuring device, because piezoelectric elements have both high measurement sensitivity and high hardness, even under considerable loads. Other force measuring devices are also possible. Using a force measuring device, the forces acting on individual supports in the rolling direction can be determined. Due to the torque-free lower mounting of the receiving module, the forces applied to the supports act as torques about the axis of the torque-free mounting in the rolling direction and therefore as forces on the counter bearing. Since each receiving module is mounted in a torque-free manner independently of the other receiving modules of the support base, the forces acting on each individual support in the rolling direction can be determined in this way. This force can be used to control or regulate the rolling process in order to achieve better rolling results. However, the force measuring device can also be omitted.

[0030] Particularly preferably, a limiting element is arranged between the receiving module and the counter bearing to protect the force-measuring device from overload. This can be, for example, a stop that limits the spring travel of a spring-based force-measuring device and thus prevents excessive deformation of the force-measuring device. However, such a limiting element is not mandatory.

[0031] Advantageously, the counter-bearings of the receiving modules are fastened to a common cover frame. Similar to the common base frame, the cover frame absorbs the forces acting in the rolling direction on the supports received in the receiving modules during operation and thus prevents these forces from being introduced directly into the cover structure. This ensures greater stability of the support base and, consequently, greater precision in the relative positioning of the supports in the receiving modules relative to one another. In this case, the cover frame preferably extends over the entire extent of the rolling mill in the rolling direction, but it can also cover only a smaller length, and the rolling mill can therefore include several such cover frames. However, it is also possible to fasten the counter-bearings directly into the cover structure.

[0032] Advantageously, each receiving module comprises a longitudinal drive with a gripper device, so that the holder can be pushed into the receiving module and out of the receiving module through the lateral opening.

[0033] The longitudinal actuator can be, for example, a hydraulic cylinder or an electric actuator powerful enough to pull the bracket into the receiving module and push it out of the receiving module. This movement through the side opening allows the bracket to be replaced for maintenance or other reasons. Alternatively, a correspondingly designed external device can be used to introduce the bracket into the receiving module or remove the bracket from the receiving module.

[0034] Hooks, eyelets, sliders, or other devices may be used as the gripper means. The specific design of the gripper means may be matched to the bracket provided for the receiving module. It is also contemplated that adapters for different gripper means may be operably connected to the longitudinal drive to enable use with different brackets. However, typically, the bracket base is designed for a predetermined bracket type and shape, so that such adapters are generally not required.

[0035] Advantageously, two different receiving modules for receiving supports in two different configurations are arranged alternately one behind the other. In the case of a three-roller stand, the different configurations may be a Y-arrangement and an inverted Y-arrangement. Stands comprising more or fewer rollers may be completed with corresponding configurations of the stands to form round rollers. If the material to be rolled is not intended to be rolled into a round shape, alternative configurations may also be provided, provided this is beneficial to the rolling result. However, this is not necessarily the case.

[0036] The preferred protective flap is particularly preferably designed to be pivotable hydraulically or electrically. However, it can also be pivotable manually or be removable from and attached to the intermediate space in another manner. The hydraulically or electrically pivotable design of the protective flap makes it particularly easy to secure the intermediate space in a controlled, reliable, and documented manner.

[0037] Advantageously, the preferred protective flap includes a closable opening to allow temporary access to the intermediate space. This temporary access to the intermediate space can, for example, be achieved by manually operating the roller guide. Thus, the protective flap does not have to be completely removed, for example, but can be pivoted open to allow temporary access to the intermediate space, which allows for more efficient operation of the rolling mill. However, such an opening can also be omitted.

[0038] Preferably, a bracket is received in each of the receiving modules.

[0039] Further advantages and developments of the invention emerge from the following description of the drawings and from all claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1 1 is a perspective side view of a preferred support base 10. The support base 10 comprises four receiving modules 12 arranged one behind the other in the rolling direction W. Each receiving module 12 is adapted to receive a support 14. Narrow intermediate spaces 16 are located between adjacent receiving modules, which intermediate spaces are narrower in the rolling direction W than each of the receiving modules 12.

[0045] The receiving module 12 is shaped so that it can reliably receive the brackets 14, four of which are located in the Figure 1 The support 14 has a base surface oriented perpendicular to the rolling direction W and in the shape of a regular hexagon. The support housing of the support is decisive for the shape of the support 14, and the rollers 14.1, the connecting pieces 14.2, the sockets 14.3, etc. do not prevent the support 14 from being characterized as a hexagon.

[0046] Due to the hexagonal shape of the bracket 14 , the receiving module 12 has the shape of a partial negative hexagon. Figure 1 The receiving module 12 shown in FIG. 1 includes four side surfaces 18, such as Figure 2 As shown in FIG, the arrangement and dimensions of the four side surfaces, in particular their equal length and the arrangement at an internal angle of 120° to each other, ensure that the four side surfaces reliably surround the hexagonal bracket 14 as viewed from the top and bottom and on the first side 68 along the rolling direction W. At the front and rear as viewed in the rolling direction W, the receiving module 12 further includes a protective wall 20 to securely surround the bracket 14.

[0047] On the side opposite to the first side 68 viewed in the rolling direction W, the opposite side faces Figure 1 To the observer in FIG, all receiving modules 12 comprise a lateral opening 66 through which a bracket 14 standing on one of the side surfaces of the receiving module can be pushed along the insertion direction E into the receiving module 12 .

[0048] Further located on the receiving modules 12, in the insertion direction E, below and behind, i.e., on a first side of each of the receiving modules 12, are slide rails 22, on which the holder 14 can be pushed into the receiving module 12 in a low-wear manner and in a defined position. The slide rails 22 can also serve as a seal against splash water.

[0049] Protective flaps 24 are formed between all adjacent receiving modules 12, which cover the intermediate spaces 16 between adjacent receiving modules 12. Thus, the intermediate spaces 16 are protected from rods escaping from the intermediate spaces 16 or from water escaping, and from people reaching into the intermediate spaces 16.

[0050] The protective flap 24 is designed to be pivotable via a hinge 26 arranged in the upper region between the receiving modules 12. Thus, the intermediate space 16 can be covered and released by the protective flap 24, for example in order to carry out work in the intermediate space 16 between the receiving modules 12 when no rolling is currently being carried out, but also in order to facilitate the replacement of the holder 14, in particular the pushing in or pushing out of the holder 14. In order to allow temporary access to the intermediate space 16, the protective flap 24 comprises a closable opening, which can be opened at Figure 1 In the embodiment shown in FIG, the closable opening is covered by a hand hole cover 30. Opening the hand hole cover 30 is significantly faster and less labor-intensive than opening the entire protective flap 24, especially when all protective flaps 24 of the stand base 10 are pivoted open and closed by a common drive.

[0051] Figure 2 FIG. 1 is a schematic diagram of a preferred installation of two receiving modules 12 of a support base 10 . Figure 2The two receiving modules 12 shown in FIG are fastened to a common lower base frame 32 and a common upper cover frame 34. The receiving modules 12 are mounted in the base via the common lower base frame 32. The receiving modules 12 are mounted in the base at the bottom in a torque-free manner via the common lower base frame 32 by means of joints 36 having an inclination axis K. In other words, the receiving modules 12 are mounted at the bottom so that they can be moved along the Figure 2 A rolling direction W, which corresponds to a main extension direction of the base frame 32 , is tilted about the joint 36 , so that forces acting on the receiving module 12 along the rolling direction W generate a torque about the tilt axis K of the joint 36 .

[0052] The receiving module 12 rests on the counter bearing 38 at the top with the stop 40 of the receiving module 12. Figure 2 As can be seen in FIG, the joint 36 is located off-center at the bottom on the receiving module 12 along the rolling direction W, so that the gravity acting on the receiving module 12 causes the joint 36 to move toward the receiving module 12. Figure 2 A tilting moment on the left side (i.e., opposite to the rolling direction W) is generated. This tilting moment counteracts the counter bearing 38 at the top, so that the receiving module 12 rests firmly on the counter bearing 38 with the stop 40. The additional force on the support 14 received in the receiving module 12 is superimposed on the force of the receiving module 12 resting on the counter bearing 38 at the top, thus changing the force acting on the counter bearing 38. This allows conclusions to be drawn about the forces acting on the material to be rolled via the support 14, which are valuable for regulating and controlling the rolling process.

[0053] For force measurement, a force measuring device 58 , which can be designed as a piezoelectric element, for example, is arranged between the counter bearing 38 and the stop 40 of the receiving module 12 resting thereon.

[0054] exist Figure 2 In the embodiment, one of the two receiving modules 14 is provided with a bracket 12, while the other of the two receiving modules 14 is shown empty. Figure 1 In addition to the elements described, the empty receiving module 14 also illustrates a holder 42 for an electrical or hydraulic remote adjustment member of a roller guide attached to the support 12. Such a roller guide is optional and can be adjusted by a remote adjustment member (i.e., by an electric motor) or manually, or can be designed so that no adjustment is performed, but rather a force is continuously exerted on the roller in the direction of the material to be rolled, for example by a spring.

[0055] In addition, hook 44 is Figure 2By means of the hook, the bracket 14 can be pulled into or pushed out of the receiving module 12. The hook 44 is operatively connected to a longitudinal drive 46, via which the force required to push the bracket 14 in and out can be provided.

[0056] Figure 2 The receiving module 12, shown empty, comprises openings 48 in its side surface 18. A plurality of such openings 48 are provided for the drive shafts of the rollers of the support 14. Via said openings 48, couplings of the roller shafts can reach the outside from the side of the support 14 through the receiving module 12, where the roller shafts can be coupled to corresponding drives.

[0057] Furthermore, two first operating substance connections, designed as water connections 50, are shown in the receiving module 12. One or more corresponding connections on the holder 14 can be coupled to the water connections 50, wherein the holder 14 is pushed into the receiving module 12. For this purpose, the holder 14 can be provided with corresponding connectors, which penetrate into the water connections 50 of the receiving module and thus establish a watertight connection.

[0058] Also shown is a second operating substance connection designed as air connection 52. Air connection 52 is also positioned and designed similarly to water connection 50 so that it can be coupled to a corresponding connection on bracket 14, wherein bracket 14 is pushed into receiving module 12.

[0059] Figure 3 is a schematic diagram of a preferred receiving module 12 of a support base 10. In this figure, remote adjustment members 54 for rollers attached to the roller guide of the support are indicated, said remote adjustment members being held in holders 42 for remote adjustment members. In addition, Figure 3 Also shown are electrical or hydraulic remote adjustment means 56 of the rollers of the stand attached to the receiving module 12 , which are attached obliquely at the top to the receiving module 12 and allow simple coupling to corresponding remote adjustment connectors of the stand. Figure 3 The display is also Figure 2 The hook 44 and the longitudinal drive 46 operatively connected to the hook 44 are illustrated in FIG.

[0060] From Figure 2 The empty receiving module from Figure 3 The comparison of the receiving modules of FIG. 1 shows that the water connection 50, the air connection 52 and the opening 48 for the roller drive are arranged in different positions. The receiving module 12 is configured for two different arrangements, specifically once for a so-called Y arrangement of the rollers and once for a so-called reverse Y arrangement of the rollers.

[0061] The modular design of the support base 10 makes it possible to switch between different arrangements in an extremely flexible manner, wherein in each case a suitable receiving module 12 is easily positioned in the support base 10, said receiving module being able to be mounted in the same way, being able to be supplied with the same operating substances and allowing the same mechanism for pushing the support 14 in and out and also for the same force measurement.

[0062] Figure 4 is a schematic diagram of a preferred protective flap 24 of the support base 10 . Figure 4 The protective flap 24 is shown in the closed position. The protective flap 24 includes the Figure 1 The hand hole cover 30 is explained, as well as two windows 60 to enable observation of the intermediate space 16 between adjacent receiving modules 12. In addition, the protective flap 24 is pivotably mounted in a hinge 26 at the top so that it can be pivoted open and closed. For this purpose, Figure 4 A protective flap drive 62 is shown, in which a hydraulic cylinder applies the force for opening and closing the protective flap 24 . Figure 4 Shown are a protective plate 64 on the side opposite the lateral opening of the receiving module 12 and the upper and lower edges of the intermediate space 16, which serve in particular to drain splashing water from the intermediate space 16 in the most controlled manner possible and to reduce contamination of the support base 10.
