Description

  The present invention relates to a rolling stand for receiving a rolling load of at least three rollers, each of which is supported by a bearing seat of the rolling stand which receives the rolling load, wherein at least one of the rollers is provided in each stand. A roller bearing seat is arranged with another roller bearing seat.

  This type of rolling stand is well known in the prior art and has been used for long materials in combination with rollers for many years. In this regard, the rolling stand functions as a bearing stand in which a roller shaft into which the roller can be inserted is rotatably mounted, with the roller element fixed on the insertable roller shaft having a central caliber opening. The long material reaches the roller through this opening. In this regard, a plurality of rollers, usually three or four rollers, are arranged in one plane of each rolling stand. Basically along the roller line or the axial processing path so that a long material guided along one roller line or the axial processing path can be rolled immediately and repeatedly immediately, This type of rolling stand is arranged in a plurality of phases. It is clear that when such a rolling mill is replaced with another caliber or even due to wear, there is a correspondingly high replacement cost. This is because, in order to set the rolling mill as a new caliber, at each rolling stand, the roller elements fixed on the pluggable roller shaft must be changed accordingly. For this purpose, the pluggable roller shaft is pulled out of the bearing seat in each rolling stand and inserted or inserted again into the bearing seat after the roller element has been replaced. Often the rolling stand is finished as a slidable cassette unit, which is mounted so as to be slidable radially with respect to the roller line or axial machining path.

  The object of the present invention is to develop a rolling stand of this kind so as to simplify such a replacement, at least in terms of its adjustment.

  In this regard, the solution starts from the basic recognition that the key function is given to the stand body on which the roller is supported via the bearing seat and to the attached bearing seat. Here, this important function of the rolling stand, which is otherwise performed by the stand plate and by connection to the stand body and thus by connection to the bearing seat, is performed by the stand body or by the bearing seat itself. This basic recognition can be performed from different perspectives, cumulatively or alternatively.

  The object of the present invention is solved by a rolling stand for receiving a rolling load of at least three rollers, each of which is supported by a bearing seat of the rolling stand that receives the rolling load, wherein at least one stand is provided. A roller bearing seat is arranged in the body together with another roller bearing seat, and the rolling stand is in this case one of the stand bodies is provided with a fixed bearing of two attached rollers respectively and / or the stand body One of these is characterized by the fact that each has two attached roller movable bearings.

  In that respect, in the first bearing variant, the bearing seats of the stand body may each be provided with a fixed bearing of two rollers attached to the bearing seat, so that the two attached rollers are accurately and correctly , They are positioned relative to each other without significant adjustment. In a second bearing variant, the bearing bodies of the stand body may each be provided with two movable bearings for the rollers attached to the bearing seat, so that the adaptation or adjustment of the stand body can be easily adapted accordingly. Can be done without costly adjustments.

  Obviously, one stand body may be provided with each fixed bearing and one stand body may be provided with each movable bearing, so that benefits can be accumulated accordingly. In some cases, not all of the stand bodies can be arranged with corresponding dimensions, so in some cases one of the stand bodies may or may not be provided with a fixed bearing but also with a movable bearing, thereby Correspondingly, adjustment may be possible at a low cost.

  These two new bearing variants make it possible to perform the roller adjustment particularly easily when changing to another caliber. This is because no new adjustment of the roller shaft is required, particularly on the fixed bearing side. On the movable bearing side, the bearing seat itself of each roller shaft can be adjusted. In that respect, the conversion of the rolling stand to another caliber is particularly simple.

  Advantageously, a rolling stand that can be used universally is produced by the rolling stand of the present application. This rolling stand combines the advantages of a plug-in shaft structure from the standpoint of ease of roller replacement with the advantages of a bearing structure that is optimized and passed through a roller with the smallest possible roller diameter.

  The rolling stands of the present application are particularly adjustable and non-adjustable three-roller or four-roller rolling, especially with regard to constant diameter mills (abbreviated MW) or stretch reducers (abbreviated SRW) for finish rolling pipes, steel bars or wires. It can be a stand.

  The rolling stand preferably contains a plurality of driven rollers arranged on one surface and forming a central caliber opening, the roller shaft of which is ideally formed as a movable cassette unit. It is rotatably supported in the stand.

  The rolling stands of the present application can therefore be used universally in all known, optimized roller diameter, fixed or adjustable rolling stand configurations, in particular with bevel gears that mesh with each other. A rolling stand in which drive distribution is performed internally via (I-shaped configuration) and a rolling stand in which individual roller shafts are driven separately (A-shaped configuration) are also included.

  The roller shaft is preferably finished as a plug-in shaft element, and in this case the threaded rod and the corresponding nut are fixed to the inner ring of the bearing unit in a torsion-free manner, with the fixed bearing being positioned in the axial direction of the roller And the movable bearing is slidable through an inner ring with multi-splines cut.

  Further, in one embodiment, it is contemplated that one of the stand bodies comprises two fixed bearings of the attached roller, and another one of the two stand bodies comprises two attached roller movable bearings. . This is because it is possible in particular to simplify the roller adjustment.

  In addition, according to another aspect of the present invention, an object of the present application is to provide an alternative method for receiving a rolling load of at least three rollers, each of which is supported by a bearing seat of a rolling stand that receives the rolling load. A rolling stand, in which one roller bearing seat is arranged in each at least one stand together with another roller bearing seat, and in this case the rolling stand comprises two stand bodies, By connecting with a force element arranged in the height of the roller in one force element acting only between the stand bodies and / or radially outward and axially, and / or the roller Characterized by acting parallel to the axis.

  This also makes it much easier to adjust the roller when replacing the roller. Because, on the one hand, the stand bodies can be directly connected to each other directly above and below without any additional occupation of the mounting space and without the attachment elements to be additionally attached or removed being joined together. Because.

  Ideally, the force element in this regard may be located or provided within the stand body so that the force element does not require additional mounting space outside the stand body. On the other hand, such force elements are attached to the stand body with no or negligible protrusion. This is because it usually extends substantially parallel to the adjacent roller axis.

  The term “force element” in the context of the present invention means a functional element with which a physical frictional connection can be created between two functional components, for example the stand body of the present application.

  As a force element acting between the two stand bodies, for example, a screw element or a pivot element is provided, in which case the screw element or pivot element acts only between the two stand bodies.

  It is clear that various force elements can be formed which are arranged radially outside and axially in the region of the roller. For example, the force element may include a circular beam or the like.

  From another point of view of the present invention, the problem of the present application is solved by a rolling stand for receiving a rolling load of at least three rollers each supported on a bearing seat of the rolling stand that receives the rolling load. At least one roller bearing seat is arranged together with another roller bearing seat in each stand body, in which case the rolling stand is formed by forming the rolling stand by shape joining of all the stand bodies. It has been characterized.

  The shape bondability achieved by this makes the roller adjustment particularly simple as well when changing rollers. This is because, for example, it is not necessary to add a rolling stand frame. Moreover, the dimensions of the rolling stand can be advantageously reduced corresponding to the embodiment.

  In this connection, it is particularly advantageous if the force element comprises a screw element or a tie rod element. This is because it makes the roller adjustment easier.

  If the force element is arranged axially in the caliber bottom, i.e. in the region of the deepest indentation of the roller, on the one hand, this can be structurally simple and well centered. On the other hand, this can further reduce the dimensions of the rolling stand.

  In this respect, it is advantageous if the force element is arranged cumulatively axially in the range of the roller recess of the rolling stand for the roller drive pin of the roller, so that this is already sufficiently centered Placement can be guaranteed. Furthermore, this reduces the load by which the force element is pulled by the rolling load as much as possible.

  Furthermore, the object of the present invention is solved by a rolling stand for receiving a rolling load of at least three rollers, each of which is supported by a bearing seat of the rolling stand that receives the rolling load. A bearing seat of one roller is arranged with a bearing seat of another roller in the stand body, in which the rolling stand is characterized by the two stand bodies being in contact with each other via contact surfaces .

  Since the two stand bodies are in contact with each other via a common contact surface, the roller adjustment at the time of replacement can be similarly simplified. This occurs in particular because the two stand bodies can interact so that they are directly connected to each other, so that, for example, an additional rolling stand frame or the like can be omitted, thereby adjusting the roller adjustment. The entire assembly process can be simplified.

  From another aspect of the present invention, the given problem is solved by a rolling stand for receiving a rolling load of at least three rollers each supported on a bearing seat of the rolling stand that receives the rolling load. In this case, at least one first roller bearing seat is arranged together with another roller bearing seat in each stand body, in which case the two stand bodies are directly connected via one contact surface. It is characterized by that.

  In that respect, the two stand bodies are connected to each other so that they can function reliably to form the frame unit of the rolling stand, and the rolling stand can be opened more easily if necessary. It becomes very easy. Through this contact surface, for example, the working force generated by the roller or the like can be transmitted directly between the two stand bodies, so that they can be supported directly on the contrary.

  In this regard, the contact surface, like the force elements already described above, may preferably be provided in the area of the caliber bottom or in the area of the roller recess of the rolling stand, so that a particularly low load is possible as well. It can be guaranteed in a range of planes.

  In particular in this connection, it is advantageous if the connection is made via a hinge or by a separable connection, for example a screw connection.

  If the contact surface is arranged in a low force range, the dimensions of the hinge connection or screw connection can be reduced in some cases. This is because the working force they have to receive or the like is smaller.

  Correspondingly, the problem imposed here in accordance with the additional aspects of the invention is also to receive the rolling load of the rollers supported by the bearing seats of the rolling stand, each of which is at least three each receiving the rolling load. In this case, at least one roller bearing seat is arranged together with another roller bearing seat in each of the stand bodies, in which the two stand bodies of the rolling stand are arranged. It is characterized by being connected to each other in a range where the rolling load is small.

  This can ensure a load reduction as wide as possible in the force element or other components and / or the stand body range connecting the two stand bodies, so that the dimensions can be made smaller and thus also Installation space can be saved.

  In this regard, it is advantageous if the two stand bodies are connected to each other on the side facing one of the roller calibers.

  In addition, the problem of the present invention is further solved by a rolling stand for receiving a rolling load of at least three rollers, each of which is supported on a bearing seat of the rolling stand that receives the rolling load on each side. The bearing seat of one roller is arranged with the bearing seat of another roller in each one stand body, and the rolling stand in this case is that the two stand bodies in one guide are movable relative to each other It has been characterized.

  This also makes it possible to adjust the roller particularly easily when replacing the roller. This is because the two stand bodies are guided to each other when the rollers are exchanged. It is clear that this makes handling of the stand body much easier.

  Advantageously, the guide comprises two lateral stand plates, so that at least two stand bodies are easily movable relative to one or a further stand body of the rolling stand. These stand plates can be prepared for various purposes. Preferably they are formed from one of the stand bodies so that no further components are required for this purpose.

  In addition, it is likewise advantageous if the guide acts directly between the bearing seats, for example as a rotary joint. This allows the stand bodies to be substantially central and can fold together in the region of the roller element, which makes access to the roller element particularly easy.

  The problem of the invention is further solved by a rolling stand for receiving a rolling load of at least three rollers, each of which is supported by a bearing seat of the rolling stand that receives the rolling load. The bearing seat of one roller is arranged with the bearing seat of another roller in one stand body, and in this case at least one of the bearings provided in the bearing seat, in particular in the bearing seat, is in the attached roller. Characterized by intrusion.

  This makes it much easier to adjust the roller when replacing the roller. This is because the bearing seat can help during pre-positioning. In addition, in a suitable embodiment of the bearing seat, less installation space is required on the rolling stand, and this is independent of the bearings in the common bearing seat, which is also the installation space. Is advantageous for smaller embodiments.

  Yet another important advantage of the present invention is that the modular rolling stand structure allows smaller, interchangeable assembly and manufacturing units, such as rolling stands or cassette units, and flexibility in manufacturing and procurement. It will be mentioned that the improvement can be seen in achieving. Also, the dimensions in a continuous form are expanded. As already mentioned, the roller change is also achieved more quickly and easily without removing the roller bearing unit and / or the miter gear unit which has failed to fit into the rolling stand or the corresponding stand body.

  In addition, the rolling stand load remains unchanged and the same caliber size is achieved while making the rolling stand size smaller and thereby smaller with optimal and smaller roller diameter, improved deformation conditions, smaller rolling stand spacing Rolling stand dimensions, improved material transfer by reducing end loss, reduced investment and operating costs, a compact and stable structure are easily achieved structurally with minimal space requirements.

  It is clear that the features of the solutions described in the preceding claims can be combined as required in order to be able to realize the benefits correspondingly cumulatively.

  Further advantages, objects and characteristics of the invention are explained on the basis of the description of the following examples, in particular also in the subsequent figures.

FIG. 10 is another schematic diagram of the rolling stand of FIG. 9 in a state where the roller shaft is pulled out from the bearing seat. FIG. 11 is another schematic view of the rolling stand of FIGS. 9 and 10 without a roller element. It is a typical perspective view of rolling equipment provided with a plurality of rolling stands which can be arranged one after another along a roller path. It is a typical fragmentary sectional view of the rolling equipment of FIG.

  The first embodiment shown in FIGS. 1 to 4 comprises a rolling stand 1 and comprises a total of three stand bodies 2, 3 and 4, in which three rollers 5, 6 and 7 are located. Are supported concentrically around the roller line 8 or around an axially extending machining path, in which case the three rollers 5, 6 and 7 are used to roll a rolling material not shown here. Forms Caliber 8A.

  Each of the rollers 5, 6 or 7 is composed of a roller shaft 9, 10 or 11 and the roller elements 12, 13 or 14 attached thereto, and these three roller elements 12, 13 and 14 form a caliber 8A, in particular It can be recognized very well from the depictions of FIGS.

  Each of the stand bodies 2, 3 and 4 has a shape with many corners, whereby two of the three roller shafts 12, 13 and 14 respectively correspond to bearing seats 2A, 2B, 3A, 3B or 4A and 4B is prepared.

  As can be recognized in particular by the depiction of FIG. 4, the first stand body 2 forms a first movable bearing 2 </ b> C for supporting the first roller shaft 9 and supports the third roller shaft 11. The second movable bearing 2D is formed to form two bearing seats 2A and 2B. In response to this, the second stand body 3 forms the first movable bearing 3C for supporting the first roller shaft 9 to provide the first bearing seat 3A and the second roller shaft 10. A further movable bearing 3D for bearing is formed to form a second movable bearing 3B. In addition, the second stand body 3 further has a fixed support 3E for fixing the first roller shaft 9 in the axial direction. Further, the third stand body 4 similarly forms a first bearing seat 4A and a second bearing seat 4B, in which case the second roller shaft 10 is placed in the first bearing seat 4A, and the second bearing seat 4A. The third roller shafts 11 are supported by the third stand body 4 in the bearing seat 4A. Here, the first bearing seat 4A is designed as the first fixed support 4C of the third stand body 4, and the second bearing seat 4B is designed as the second fixed support 4D of the third stand body 4. .

  In this embodiment, the movable bearings 2C, 2D, 3C and 3D are finished as tapered roller bearings arranged in X, respectively, while the first fixed bearing 4C and the second fixed bearing 4D are finished as tapered roller bearings, respectively. Yes. Furthermore, the additional fixed bearing 3E is finished as an axial deep groove ball bearing acting on both sides.

  In this regard, the first roller shaft 9 is around the first insertion axis or rotation axis, the second roller shaft 10 is around the second insertion axis or rotation axis 16 and the third roller. The shaft 11 is supported in the rolling stand 1 around a third insertion shaft or rotating shaft 17 so that it can be easily replaced structurally and rotated. As can be seen in particular in the depictions of FIGS. 2 and 3, the roller shafts 9, 10 and 11 are each finished as plug-in shaft elements (not specifically labeled here) so that the roller exchange can be carried out smoothly. ing. The fact that the individual roller shafts 9, 10 or 11 can be plugged in well means that the individual roller shafts 9, 10 and 11 themselves are not directly supported on the respective stand bodies 2, 3 or 4 and corresponding bearing bushing elements. By being indirectly supported as is known from the prior art by means of 20 (referenced here by way of example only), a simple construction is guaranteed.

  According to the first embodiment of the present application, the bearing bushing element 20 is on the one hand formed as a direct bevel gear 21, 22, 23 or 24. On the other hand, the bearing bushing element 20 is formed as a blind hole bushing 25 or as through bushings 26 and 27.

  With the help of the bevel gear 23 or 24, the second roller 6 or the third roller 7 is in operative contact with the bevel gear 21 or 22 of the first roller 5, so that the rollers 6 and 7 are known per se (known per se). Both) can be driven by the first roller 5. In this regard, the first roller shaft 9 of the first roller 5 is also the input shaft 9A.

  The first roller shaft 9 has a total of four multispline areas 30, 31, 32 and 34. Using the first multispline range 30, a drive connection to a drive element not shown here is realized. Using the second multi-spline range 31, a connection by shape joining to the first bevel gear 21 is realized. Correspondingly, a connection by shape joining to the first roller element 12 using the third multi-spline area 32 and a blind hole in the second bevel gear 22 using the fourth multi-spline area 33. As long as the first roller shaft 9 is inserted into the rolling stand 1, the connection by shape joining to the bush 25 is realized (particularly see FIG. 1).

  In contrast, the second roller shaft 10 comprises only two multispline areas 34 and 35, in which case the second roller shaft 10 is associated with a third bevel gear 23 with a third bevel gear 23. One multi-spline area 34 is in operative contact, and the associated second multi-spline area 35 is connected to the second roller element 13 in a form joint.

  Correspondingly, the third roller shaft 11 comprises two separate multi-spline areas 36 and 37, in which case the third roller shaft 11 uses the first separate multi-spline area 36 to The bevel gear 24 is operatively connected. Using a second alternative multi-spline area 37, if this is the case when the third roller shaft 11 is correspondingly inserted into the rolling stand 1, as can be seen for example in the depiction of FIG. The third roller shaft 11 is operatively connected to the third roller element 14 by shape joining.

  According to the described structure of the rolling stand 1, the two bearing seats 2A and 2B of the first stand body 2 are formed as movable supports 2C or 2D, respectively. This also applies to the first bearing seat 3A and the second bearing seat 3B of the second stand body 3. This is because these two bearing seats 3A and 3B are likewise formed as movable bearings 3C or 3D, respectively. In this respect, the rollers 5, 6 and 7 are arranged in the stand bodies 2 and 3 of the rolling stand 1 with self-calibration with respect to their position after conversion to another caliber 8A, so that the roller adjustment is correspondingly simple become,

  The second roller 6 and the third roller 7 are locked by the two bearing seats 4 </ b> A and 4 </ b> B of the third stand body 4 so that there is no undesirable axial displacement. This is because they are designed as fixed bearings 4C or 4D, respectively. In order to lock the first roller 5 against such an undesirable axial displacement, the second stand body 3 is further provided with a fixed support 3E in addition to the two movable supports 3C and 3D. In use, the blind hole bush 25 and thereby the first roller shaft 9 are also reliably supported on the second stand body 3 so as to be axially repositionable accordingly. Thereby, the first stand body 2 has only a movable support and the third stand body 4 has only a fixed support, while the second stand body 3 has both a fixed support and a movable support, Naturally, in this respect, such a roller arrangement shows an inevitable mixed shape.

  Thus, the third stand body 4 comprises two fixed supports 4C and 4D of the attached rollers 6 and 7, and another stand body corresponding to these two rollers 6 and 7 comprises movable supports 3D and 2D. .

  It is further mentioned here that the three stand bodies 2, 3 and 4 are fixed to the rolling stand 1 of the present application, using a rolling stand frame part not further shown here.

  Since the second embodiment of the rolling stand 101 shown in FIGS. 5 and 6 has substantially the same structure as the rolling stand 1 of the first embodiment shown in FIGS. In order to avoid repetition, only component components that have been modified or formed differently with respect to the second embodiment will be described.

  The rolling stand 101 also comprises three stand bodies 102, 103 and 104, with the stand bodies 102, 103 and 104 acting between adjacent stand bodies 102/103 or 103/104 or 104/102, respectively. Force elements 150, 151 and 152 are used to operatively connect to each other. That is, the stand bodies 102, 103 and 104 receive the rolling load and, in suitable embodiments, are connected to form a rolling stand unit without a separate rolling stand frame (not shown) surrounding it. Yes.

  This further simplifies the shape of the rolling stand 101 so that, for example, very simple adjustments of the rollers 5, 6 and 7 can be made when changing the rollers or switching the rollers to another caliber 8A. .

  The first force element 150 is formed by a screw connection 153 in this second embodiment. In this case, the hole 154 of the screw connection 153 associated therewith extends parallel to the plug-in shaft or the rotary shaft 15 of the first roller 5, with the original screw element 155 being inserted into the first stand body 102. Alternatively, it is screwed into the through screw hole 156 and further screwed into the blind screw hole 157 in the second stand body 103.

  In this respect, the two stand bodies 102 and 103 are in direct contact with each other via contact surfaces 160 and 161 (see FIG. 6). This eliminates the need for component components that form a further rolling stand frame, thereby further simplifying the adjustment when replacing the rollers 5, 6 and 7.

  The second and third force elements 151 or 152 are formed by hinge connections or corresponding guides 165 or 166, respectively. In this case, the two stand bodies 104/103 and 104/102 are movable relative to each other within each guide 165 or 166.

In this regard, the first guides 165 of the two stand bodies 104 and 103 use the first rotary joint 167, and the second guide 166 is the third stand body 104 and the first stand body 102. Using a second rotary joint 168. Either rotary joint 167 or 168 can withstand high loads, which are two lateral, stand plate elements formed from stand body 104 and each rotatably supported between two stand plate elements, respectively. This is realized by one hinge tab element. In this case, the hinge tab elements are each formed from a stand body 102 or 103, wherein the hinge tab element and the stand plate element are rotatably connected to each other using a screw as a rotation axis.

  In addition, the guides 165 or 166 or the rotary joints 167 or 168 are arranged in a range where the rolling load is small between the bearing seats 4A and 3B to 4B and 2B, respectively.

  In particular, the stand 101, 103 and 104 formed by this structure, and its screw connection 153 and hinge connection or guides 156 and 166 make it possible to mount the rolling stand 101 very compactly. This is because an additional rolling stand frame (not shown here) can be omitted.

  If the force elements 150, 151 and 152 are arranged radially outward and axially at the height of the rollers 5, 6 or 7, the rolling stand 101 can be made even more compact, in particular smaller. . This is especially true when the force elements 150, 151, 152 are arranged in the axial direction near the caliber bottom 170 of the rollers 5, 6 or 7 (referenced here only as an example). The caliber bottom 170 is here expressed as a range 171 with the bottom of the depression of each roller 5, 6, 7 or roller element 12, 13 or 14 related thereto. In particular, this allows each force element 150, 151 or 152 to be sufficiently centrally located.

  The rolling stand 201 shown as a third embodiment in FIGS. 7 and 8 has substantially the same structure as the two already described rolling stands 1 and 101. However, the rolling stand 201 differs from the stand body 202, 203, and 204 in particular in that it is provided with only bolt connecting portions 253, 275 and 276 in place of the hinge connection or guides 165 and 166 described above. . All the bolt connections 253, 275, 276 each include one screw element 255 (here labeled as an example) as the force elements 250, 251 and 252 which have corresponding screw holes. 254, so that the stand bodies 202, 203 and 204 are directly operatively connected to each contact surface pair 277, 278 or 279. As a result, the rolling stand 201 is formed in a particularly compact manner, and as a result, operations relating to roller adjustment are greatly simplified. The individual stand bodies 202, 203 and 204 are supported here so as to be slidable on the roller line 8 toward or away from the roller line 8 along the slide shafts 202F, 203F or 204F, respectively, in translation. As a result, the handling of the individual stand bodies 202, 203 and 204 is greatly simplified, which makes it possible to perform roller replacement more quickly. Since all other components or groups of components are the same as described above, they are only given the same reference numerals as the two previous embodiments with respect to the rolling stands 1 and 101.

  In the fourth embodiment shown in FIGS. 9-11, the rolling stand 301 shown therein includes a total of four stand bodies 380, 381, 382 and 383, which are in one rolling stand frame 384. It is surrounded by. Furthermore, the individual stand bodies 380 to 383 are operatively connected using the clamping piece elements 385, 386, 387 and 388 of the rolling stand frame 384. That is, the first stand body 380 and the second stand body 381 support each other and are supported at the rolling stand frame 384 by using the first clamping piece element 385. Further, the second stand body 381 is supported with respect to the third stand body 382 by using a second clamping piece element 386. Further, the third stand body 382 is supported at the fourth stand body 383 using a third clamping piece element 387. A fourth clamping piece element 388 is supported between the first stand body 380 and the fourth stand body 383.

  With the aid of the rolling stand frame 348 and the four clamping piece elements 385, 386, 387 and 388, the individual stand bodies 380, 381, 382 and 383 are all shown in the comparison of FIGS. Such a bearing is particularly suitable for the embodiment shown in FIGS. 1 to 4, in which the rolling stands 301 fit together and are slidably supported. Unlike the previous three embodiments, the rolling stand 301 is further characterized by two input shafts 309A and 309B, also defined as plug-in roller elements.

  In that respect, the rolling stand 301 comprises two first rollers 305, as well as a second roller 306 and a third roller 307, which together form the caliber 308 of the rolling stand 301.

  The two input shafts 9A and 9B rotate around an insertion shaft or rotation shaft 315A or 315B, respectively, while the roller shaft 309 of the second roller 306 rotates around the second insertion shaft or rotation shaft 316. The roller shaft 310 of the third roller 307 rotates around a third insertion shaft or rotation shaft 317.

  Here, the first stand body 380 forms two bearing seats 380A and 380B. Accordingly, the second stand body 381 has two bearing seats 381A and 381B, the third stand body 382 has two bearing seats 382A and 382B, and the fourth stand body 383 therefore has two bearing seats 383A. And 383B.

  The bearing seats 380A and 380B of the first stand body 380 are realized in an X arrangement in the form of a tapered roller bearing (not labeled here) as a movable bearing.

  The bearing seats 381 </ b> A and 381 </ b> B of the second stand body 381 are each formed as a fixed support (not labeled here). This fixed bearing includes an axial deep groove ball bearing acting on both sides as well as two rows of radial cylindrical bearings.

  The two bearing seats 382A and 382B of the third stand body 382 are also realized as pure movable bearings, each of which includes a tapered roller bearing in an X arrangement.

  To that effect, the two bearing seats 383A and 383B of the fourth stand body 383 are also formed as fixed bearings (here, they are not detailedly labeled). This fixed bearing of the fourth stand body 383 also includes an axial deep groove ball bearing and two rows of radial cylindrical bearings, each acting on both sides.

  In response to this, the first input shaft 9A is connected to the first stand body 380 using the bevel gear 389 via the movable bearing of the first bearing seat 380A, and to the first input shaft 9A using the blind hole head bush 390. It is supported by the second stand body 381 through a fixed support of the bearing seat 381A.

  On the contrary, the second input shaft 9B is connected to the fourth stand body 383 through the fixed support of the first bearing seat 383A using the bearing bush 391 and on the other hand using the head bevel gear 392. The third stand body 382 is supported via a movable bearing of the bearing seat 382B. In this way, the advantages already described several times can also be achieved in the rolling stand 301 of the fourth embodiment from the viewpoint of simplifying the roller adjustment.

  The second roller 6 and the third roller 7 are similarly supported in the rolling stand 301. That is, they are supported through the through bushings 326 and 327 and the bevel gears 323 or 324, respectively.

  The embodiment illustrated by way of example in FIGS. 12 and 13 shows a first possible construction of an advantageous rolling installation 1000, in which the rolling stands 1, 101, 201 or 301 mentioned above are used and Can be driven.

  In this rolling mill 1000, each stand space 1001 has a controllable drive motor 1002 and a power distribution gear 1003 each having two power take-off devices (not shown here), one stand space 1001 each. It is assigned to a rolling stand 401 at the rolling position 1004 above. The rolling stand 401 is again finished as a movable cassette element. Here, the drive motor 1002 is placed on a base 1005 that also supports the stand space 1001. In this embodiment, the rolling stand 401 includes four rollers (see, for example, FIGS. 9 to 11) each forming a caliber for a rolling material to be rolled. All rolling stands 401, according to this embodiment, are narrowed from rolling stand 401 to rolling stand 401 in the rolling direction 1006 in this example and in other examples the caliber diameters whose calibers can be changed in other shapes are Except for this structure.

  The rolling stand 401 of the even stand space 1001 is 22 in the roller stand 8 corresponding to one of the rolling directions 1006 in the roller line 8 (see FIGS. 1 to 11) in this embodiment. .Inclined with respect to 5 ° horizontal. Correspondingly, the rolling stand 401 of the odd number of stand spaces 1001 is -22.5 ° horizontal to the roller axis corresponding to one of the rolling directions 1006 in the roller line 8 in the rolling mill stand. They are offset from each other. Therefore, the rolling stands 401 are each shifted around the 45 ° roller axis with respect to the adjacent rolling stands 401.

  The individual rolling stands 401 are in this embodiment each with a roller (see FIG. 13) on the respective switching shoe 1007 guided. With this special switching device, the rolling stand can be switched in a small space in just a few minutes.

  Rolling stand switching of the even number of stand spaces 1001 is performed from the right side of the roller line 8 in the rolling direction 1006. Switching of the rolling stands of the odd number of stand spaces 1001 is performed from the left side of the roller line 8 in the rolling direction 17. There are unlabeled rails on both sides of the rolling equipment 1000, and these rails are supported by a base 1005. The movable switching vehicle 1008 has a rolling stand 401 in use and a rolling stand that is ready for use. 401 is also held until switching. Similarly, on each rolling mill side, there is a rolling stand drawing device 1009 equipped with a hydraulic drawing cylinder supported on a base 1005 for each rolling stand 401. Switching of the individual rolling stands 401 is possible without any problem using this rolling stand drawing device 1009.

  The rolling stand 401 in use is pulled from the rolling mill stand or from its stand space 1001 onto each switching vehicle 1008 by the cylinder of the rolling stand pull-out device 1009 for switching. A curve is drawn on 1010, and the rolling position 1004 in the inclined state of 22.5 ° to −22.5 ° reaches the switching position 1011 at the horizontal position on the switching vehicle 1008. Thereafter, the switching wheel 1008 moves along the rolling direction 1006 by the stand interval. Here, the rolling stand 401 prepared for switching to the rolling position 1004 is in front of the opening of the rolling mill stand, or in front of the stand space 1001 at the switching position 1001, and the cylinder of the rolling stand drawing device 1009. To the rolling position 1004 on the stand space 1001 in the rolling mill stand. When the rolling stand 401 reaches an inclined state of 22.5 ° to −22.5 ° during the movement on the switching track 1010 and is sent to the rolling position 1004, the input coupling 1012 (see FIG. 13) is driven. In order to transmit the driving force of the motor 1002, it is automatically connected to the rolling stand 401.

  The automatic coupling of the input coupling 1012 is facilitated in the range of the rolling position 1011 due to the 22.5 ° to −22.5 ° inclination state of the switching track 1010. Because there is gravity in the coupling process, no other force is required. Therefore, the rolling stand drawing device 1009 requires only a part of the driving force when the rolling stand 401 is pulled out after use when the rolling stand 401 enters the rolling position 1011. Again, the fact that the switching track 1010 is inclined increases the operational safety during rolling. This is because the rolling stand 401 is in close contact with each stand space 1001 due to its own weight and is positioned thereby. In this regard, in some cases, especially in this embodiment, an additional lock for positioning the rolling stand 401 is omitted.

  Here, the rolling stand 401 taken out from the rolling mill 1000 is supported by being slid on the switching vehicle 1008 correspondingly. After the rolling operation is performed again, the rolling stand 401 is removed from the switching vehicle 1008 using a crane. It can be transported for use and replaced with a new rolling stand 401, 101, 201, 201 or 301. Immediate maintenance and other similar measures can be performed there as needed. In this embodiment, the switching shoe 1007 preferably remains on the switching wheel 1008 when the rolling stand 401 is removed from the switching wheel 1008. Since there are two switching positions 1011 and 1011A on the common switching wheel 1008, it is clear that the setup time and thereby the stop time of the rolling mill 1000 is reduced to a minimum. This is because the conveyance to and from the rolling equipment of the rolling stand 401 is separated from the original equipment.

  The rolling stands 401 are alternately arranged along the roller line 8 or along the rolling direction 1006, as can be seen from FIG. This is even more advantageous. Thereby, the burr | flash which arises at the time of rolling depending on the case becomes smooth again when passing the following rolling stand 401. FIG. This is because each time the rolling stand 401 passes, the edges of the rollers used in each rolling stand 401 are in different positions, that is, 45 ° shifted.

  In the sectional view of the rolling equipment 1000 in FIG. 13, an even number of stand spaces 1001 arranged at an angle of 22.5 ° with respect to the horizontal and a switching device arranged on the right side in the rolling direction 1006 can be seen. The odd-numbered stand spaces 1001 are arranged in a mirror image, and the drive units 1002 of the even-numbered stand spaces 1001 are arranged below the switching position 1011 of the odd-numbered stand spaces 1001 respectively. The arrangement in which the driving units 1002 are alternately replaced further enables the use of a stronger driving unit. This is because there is more room left for the individual drives along the rolling direction 1006 and a nearly double and therefore higher torque drive can be used.

  In addition to the fact that the respective switching tracks 1010 are arranged alternately, in this embodiment, the individual switching positions 1011 to 1011A directly between the rolling stands 401 have a sufficient space at one of the switching positions 1011 or 1011A. Remaining for the rolling stand 401. This is because the stand space 1001 provided at this height is installed or replaced from another side. Therefore, since the switching wheel 1008 is shifted by the width of the rolling stand, a corresponding width can be prepared in the new rolling stand 401.
