Description
Technical Field
The invention relates to a straightening machine with an associated straightening roller drive, comprising an upper supporting frame and a lower supporting frame, in which a plurality of straightening rollers and supporting rollers are accommodated in the manner of a cassette and are arranged exchangeably.
Background
When working flat materials, such as flat steel or flat materials made of nonferrous metals, the required manufacturing steps also usually include straightening to produce flat and low-stress (steel) strips or plates. During straightening, the respective material is bent several times in the straightening machine with or without tension by means of the straightening rollers to produce the desired straightening effect. In straightening flat products, the respective product is usually guided between the upper and lower straightening roller sets and is thereby plastically deformed by the respective abutment of the upper and lower straightening rollers. In order to achieve the respectively desired plastic deformation, the bending radius is required to be different or can be different depending on the strip thickness or plate thickness and yield limit of the product or material to be straightened and is achieved by means of a suitable roller diameter, roller distribution and roller penetration depth, respectively. The result is that the smaller the roller diameter, the greater the possible plastic deformation of the product or material. However, it is not possible to use any small rollers in a straightening machine, since, on the one hand, due to the excessively high mechanical loads, the occurring bending forces may not be able to be absorbed and, on the other hand, the process moments required to give the deformation work may not be provided by means of small straightening rollers. The reason for this is that, given a roller diameter, a given roller distribution (wherein the rollers are distributed as the wheel base between two adjacent rollers), and given a penetration depth and a given or desired plastic deformation, only a defined product range or material range can be straightened in relation to the respective product thickness and its yield limit, respectively. In order to be able to design the straightening machine relatively flexibly and to be able to be adapted to different products, it is known from the prior art to use straightening machines with a replacement cassette and different roller diameters.
A straightening machine of this type is known from document EP 1584384B 1. This document discloses a straightening machine comprising a drive unit equipped with a motor and a main transmission in driving connection, wherein replacement cassettes, which are each integrally exchangeable with one another, can be coupled to the main transmission, the replacement cassettes each having straightening rollers of different diameters and different numbers of straightening rollers. In addition, the exchangeable replacement cassette with the straightening rollers having a small straightening roller diameter has a single intermediate gear integrated into the replacement cassette, which can be coupled to the main gear or to the straightening machine. Replacement cassettes are used which are each equipped with a fixedly predetermined tool set consisting of a combination of straightening and support rollers. The straightening rollers and supporting rollers present at the upper or lower supporting frame, respectively, are replaced in their entirety. In this connection, it is known from the prior art to replace the entire assembly of straightening rollers and support rollers by means of a replacement cassette, respectively.
An alternative to replacing the entire assembly by means of a replacement cartridge is described in document WO 2008/145355 a 1. This document discloses an alternative to a single straightening roll of a straightening machine. The upper and lower pairs may be replaced together as desired.
Furthermore, the requirements facing today's board production are that a large range of boards or strips of different sizes and strengths must be manufactured in small batches as well as in large quantities. As a result, the straightening machines required for this purpose must cover a large straightening range. In order to be able to cover a large straightening range, differently large straightening roll diameters and/or differently large distributions must be used in the straightening machine in order to achieve optimum straightening results. This can be achieved substantially with a replacement box straightener as described, for example, in document EP 1584384 a1, which is equipped with fixedly predetermined tool sets, i.e. a fixedly predetermined combination of straightening rollers and supporting rollers, respectively, but without the flexibility to adapt to the current production conditions. However, in order to be able to straighten a large range of sizes and strengths with one straightening machine, a plurality of different sets of replacement cassettes must be prepared. If possible, even a plurality of straightening machines must be prepared in order to be able to optimally meet the requirements for the products to be straightened respectively, that is to say thin, generally or equally thick plates.
In addition, there is therefore a need to expand existing straightening machines with regard to the straightening range that can be achieved thereby, that is to say with regard to the dimensions of the products to be treated, and in particular also to achieve cost-effective and rapid mechanical retrofitting.
Disclosure of Invention
The object of the invention is therefore to achieve a solution which offers better possibilities for matching the straightening machine to different straightening requirements and straightening ranges.
In a straightener of the type described in detail at the outset, this object is achieved according to the invention in that the entirety of the straightening rollers and the supporting rollers, which are each arranged in the upper and/or lower bearing frame, is divided into a plurality of straightening roller segments which are coordinated in a modular manner and which are each constructed in the form of a replaceable replacement cassette, wherein each straightening roller segment comprises at least one layer of supporting rollers and at least one assigned straightening roller.
Advantageous refinements and suitable configurations of the invention are specified below.
That is, the invention proposes to provide the straightening tools (modular straightening roll segments) in a modular configuration in the lower and/or upper cassettes or in the upper and/or lower support frames in order to ensure a cost-effective and rapid mechanical modification to enlarge or adapt the straightening range of the straightening machine. The respective modular straightening tool or the respective tool module is composed of modular segments, which are designed in the manner of replaceable replacement cassettes, wherein each straightening roll segment has at least one layer of supporting rollers and at least one assigned straightening roll. That is, the respective straightening roll segments form modular segments, which each form a tool module, wherein the upper and/or lower support frame is a tool carrier. It is thereby possible to provide the upper and/or lower support frame alternatively and replaceably with a variable number of modular straightening roll segments or tool modules, each consisting of a straightening roll and a support roll combination with different diameters, distributions, roll material, and each being selected in order to optimally adapt to the respective straightening target to be performed, in particular the respective material to be straightened. It is possible to replace only individual modular straightening roll segments of the supporting frame or, however, all the straightening roll segments of the supporting frame and thus to adapt the straightening machine accordingly.
Due to the modular design, it is furthermore possible to realize a large number of different straightening roll segment combinations in the straightening machine and thus to achieve significantly better possibilities for adapting the straightening machine to different straightening requirements and straightening ranges. It is also possible here to considerably enlarge the entire straightening range of the straightening machine by suitable selection of the respective straightening roll segments, in connection with which the grading of the diameter of the straightening rolls and the distribution achieved thereby are selected. It is also possible to equip the straightening machine with the appropriate selection of the straightening rolls actively participating in the straightening process, in accordance with the respective desired technical requirements of the straightening process, and thus to improve the straightening quality. In the case where only the straightening rolls of the straightener rig are worn, it is also possible to replace only the modules with the straightening rolls. It is then no longer necessary to replace the entire set of straightening machines, including all the straightening rolls.
Therefore, the leveler can be equipped based on the sheet material parameters and the tool load history, that is, the leveler roll load history. The individual straightening rolls of the straightening machine are loaded to different degrees during the straightening process and thus have different operational service lives. In this case, the tool subjected to particularly high loads can be exchanged. However, within the scope of the replacement circuit, different modules of the same form may be periodically replaced depending on the determined position within the upper and/or lower support frame of the straightener.
Another advantage of the invention is that in the straightener now only the less heavy units have to be replaced. This is achieved by working with a crane capacity having a smaller load capacity than would be necessary when the entire set of straightening machines comprising all straightening rolls has to be replaced as a whole. Also, the space requirement necessary for the individual modular straightening roll segments is smaller than for the entire set of straightening rolls. Furthermore, the smaller weight and the smaller size of the modular straightening roll segments compared to the entire set of straightening rolls and/or supporting rollers can now also be achieved, if necessary by setting up a tool center or a machining center near the straightening machine.
In general, the following advantages can be achieved with the present invention:
-reducing the transport weight and size of the tool module;
-optimally configuring the straightening tool according to the product to be straightened;
-a straightening roll/backup roll combination that is expandable and can be matched to the changes of the product program to be processed with the straightener;
-reducing investment costs with respect to a cassette solution replacing the whole set;
-minimizing the preparation time by the modular structure of the straightening/support roller unit;
by periodically replacing the straightening/supporting roller units within the magazine, the service time/service life of the tool can be unified.
In one embodiment, the invention provides that the straightening roll segments, which are coordinated with one another in a modular manner, are designed to be exchangeable individually or in groups and are arranged in the upper and/or lower supporting frame. This ensures complete, at least overall, flexibility in the positioning of the individual straightening roll segments.
In order to be able to equip the straightening machine with straightening rollers in different positions in a particularly flexible and replaceable manner, it is advantageous according to a development of the invention if not only the entirety of the straightening rollers and supporting rollers arranged in the upper supporting frame but also the entirety of the straightening rollers and supporting rollers arranged in the lower supporting frame are arranged in a plurality of respectively modularly mutually coordinated straightening roller segments which are designed in the manner of replaceable cassettes.
In order to be able to provide a good adaptation to different straightening requirements and straightening ranges, it is furthermore expedient if the entirety of the straightening rollers and supporting rollers, which are arranged in the upper and/or lower supporting frame, respectively, is divided into modular straightening roller segments or replacement cassettes of the same or different size type.
In addition, it is expedient to use different types of modular straightening roll segments, so that the invention also provides that the entirety of the straightening rolls and supporting rollers, which are arranged in the upper and/or lower support frame, respectively, is divided into modular straightening roll segments or replacement cassettes of the type which are equipped differently with straightening rolls and/or supporting rollers with respect to the diameter of the respective straightening rolls and/or supporting rollers and/or with respect to the number of the respective straightening rolls and/or supporting rollers.
It is particularly advantageous if the individual modular straightening roll segments each form a replacement cassette and are each coordinated with one another in such a way that they form, in their entirety, a replacement cassette system made up of replacement cassettes that can be replaced by one another. The invention is therefore further characterized in that the individual modular straightening roll segments form a replacement cassette of a replacement cassette system which can be replaced individually or in groups.
Such a replacement cassette system can comprise modular straightening roll segments or replacement cassettes of different size types, which solution is likewise provided for by the invention.
The replacement cassette system can comprise modular straightening roll segments or replacement cassettes of the type which are equipped differently with straightening rolls and/or support rollers with regard to the diameter of the respective straightening roll and/or support roller and/or with regard to the number of the respective straightening roll and/or support roller, and the invention is further distinguished therefrom.
In order to be able to acquire operating data and wear states and thus to determine and obtain the service life of the straightening rollers and the necessary replacement cycles, the invention finally also provides for the straightening rollers to have means for acquiring and/or storing material parameters of the material to be straightened and/or means for acquiring and/or storing method parameters acting on each modular straightening roller section during the straightening process and/or state parameters set at each modular straightening roller section according to the straightening process.
The modular, mutually coordinated straightening rollers are in each case replaceable, complex elements of the straightening machine, which in each case form a closed functional unit and in this respect form a "modular straightening roller segment".

Detailed Description
Figure 1 shows a straightener indicated as a whole by 1, comprising an upper supporting frame 2 and a lower supporting frame 3. Three straightening roller segments 4, 5 and 6, which are coordinated in a modular manner with one another and are each designed in the form of a replaceable replacement cassette, are arranged in the upper supporting frame 2, and the entirety of the straightening rollers 7 and the supporting rollers 8 arranged in the upper supporting frame 2 is divided into the straightening roller segments 4, 5 and 6. The three modular straightening roll segments 4, 5, 6 are of uniform design in this exemplary embodiment and each have not only the same number of straightening rolls 7 and support rollers 8 but also straightening rolls 7 and support rollers 8 of the same diameter. In the modular straightening roll segments 4, straightening rolls 2', 4' and 6' are arranged, respectively, in the straightening roll segments 5 and 6.
Four straightening roller segments 9, 10, 11 and 12, which are coordinated in a modular manner with one another and are each designed in the form of a replaceable cassette, are arranged in the lower supporting frame 3. The entire straightening roller 7 and support roller 8 arranged in the lower support frame 3 is subdivided into straightening roller segments 9, 10, 11 and 12. In this case, the straightening rollers 7 of the individual modular straightening roller segments 9 to 12 also have the same diameter and the same number of straightening rollers 7 is formed in each modular straightening roller segment 9 to 12. In the same way, the modular straightening roll segments 9-12 are equipped with respectively the same diameter and the same number of supporting rolls 8. If a replacement should now be made in respect of one or more straightening rollers 7 and supporting rollers 8, the individual modules 4-6 and 9-12 can be replaced or exchanged independently of one another. Thereby, the straightener 1 can be adapted to different straightening requirements.
Fig. 1a shows a modular lower straightening roll segment 9 in a side view in the machine direction 40 in a schematic side view. It can be seen how one straightening roll 7 is supported by a plurality of support rollers 8.
Fig. 2 shows the lower supporting frame 3 in which the modular straightening roll segments 10 and 11 according to the embodiment of fig. 1 have been replaced by four half-width straightening roll segments 13-16. The modular straightening roll segments 13 to 16 are identical to one another, but have a significantly smaller roller and roll diameter than the straightening roll segments 9 and 12.
In the left-hand partial drawing of fig. 2, which is now shown in dashed lines, individual modules, in this case, for example, the modules 12 and 15, can be exchanged in the scope of a tool retrofit. However, it is also possible to replace a plurality of straightening roll segments in groups, which are shown, for example, in the middle in FIG. 2 by a dash-dot line. The detached straightening roll segments 13-16 are replaced by straightening roll segments 17-19 to be installed. The right-hand part of fig. 2 shows the periodic replacement of the individual modular straightening roll segments 13-16. The straightening roll segments 13 are removed in this case, and then the straightening roll segments 14 to 16 are slid in the lower supporting frame 3 to the straightening roll segments 9 in order to close the gap created by the removed straightening roll segments 13. Subsequently, the straightening roll segment 13 is inserted again into the gap created on the side of the straightening roll segment 12. In this way, the individual straightening roll segments 13-16 can be introduced into positions which are exposed to different mechanical loads during the straightening of the sheet material guided through the straightening machine. Thereby, a uniform wear of the straightening rolls of the straightening roll segments 13-16 can be achieved.
Fig. 3 shows exemplary combinations of the arrangement of the different modular straightening roll segments 9-21 in their lower supporting frame 3. In a similar manner, fig. 4 shows a schematic illustration of different arrangements and combinations of modular straightening roll segments 4-6 and 22-30 in the upper supporting frame 2.
As can be seen from fig. 3 and 4, not only can differently large rollers and/or rollers be combined in any desired manner, but the distribution (wheelbase) also varies in each case as a function of the pairing.
In a manner not shown, the individual straightening roll segments can also be moved vertically and upwards or downwards relative to the sheet material passing through the straightening machine, so that they are not continuously in mechanical contact with the sheet material to be worked, as is known in principle from the processing of sheet materials by means of straightening machines. In this connection, the number of the respectively active straightening rolls 7 can be changed without having to replace individual modular straightening roll segments.
In fig. 5, the acquired state parameter "straightening roll actual diameter" and the acquired method parameter "sheet data acquisition are schematically illustrated: how the processing of temperature, strength, thickness "can be used to obtain automated assistance and display by means of the stored data and the computing and storage unit is whether, on the one hand, the correct tool combination, that is to say the combination of modular straightening roll segments required in the present case to achieve the desired straightening result, is set and present, and whether it also has the necessary state parameters, that is to say, for example, a sufficient straightening roll diameter. This is checked before the beginning of the sheet straightening process and in case the combination of the existing modular straightening roll segments should be determined to be insufficient or unsatisfactory, a tool replacement or exchange of the individual modular straightening roll segments is carried out. Only then does the plate straightening process start.
FIG. 6 shows a schematic view of the layout of a leveler 1 according to the present invention, where the leveler 1 has a given leveler roller drive mechanism 31 that includes a main drive mechanism 32 and a main transmission mechanism 33 and a power transmission system 34. On the side opposite the straightening roller drive 31, a tool machining station 35 is arranged, which comprises a grinding machine 36, a stock of modular straightening roller segments with a straightening roller group 37 and a tool room with a crane rail 38.
The modular straightening roll segments 4-6 and 9-30, depending on their position of use in the upper supporting frame 2 or in the lower supporting frame 3, are modularly coordinated with one another with respect to their respective width 43, 44 in relation to the frame width 41 of the lower supporting frame 3 or the frame width 42 of the upper supporting frame 2 measured in the machine direction 40 of the sheet material to be processed, so that a modular straightening roll segment or a plurality of modular straightening roll segments can be placed in each case at positions defined by multiples of the respective width 43, 44 or the respective width 43, 44. In this case, it is of course also possible for a specific position to be set free, in which case a corresponding block not equipped with a straightening roller 7 is inserted.
