Description

The invention relates to the correct machine with the corresponding drive of the correct rolls, containing the upper support frame and the lower support frame, in which there are many correct rolls and support rollers, combined in the form of a cassette and made with the possibility of replacement.

When processing sheet material, such as strip steel or sheet material from non-ferrous metal, necessary technological operations include, as a rule, also straightening for the production of flat and free from internal stresses (steel) strips or sheet metal. When dressing the appropriate material to obtain the desired effect, the edits are repeatedly subjected to bending with or without pulling in the correct machines with the correct rollers. When straightening flat products, the corresponding product is usually carried out between a group of upper and lower regular rollers and, at the same time, is subjected to plastic deformation by appropriate adjustment of the upper and lower regular rollers. In order to achieve the desired plastic deformation, in each case a certain radius of bending is required, which has or may have a different value depending on the thickness of the tape or sheet of metal and the yield strength of the product or material being straightened, and which is realized in each case by means of suitable roller diameters, roller distributions and roller depths. In this case, the possible plastic deformation of the product or material is the greater, the smaller the diameter of the rollers. However, arbitrarily small rollers cannot be used in the correct machine, since, on the one hand, efforts cannot be perceived to be flexible when they occur and, on the other hand, the moments of forces necessary for the process during the molding work cannot be created during using small correct rollers due to excessive mechanical load. This is the reason that for a given diameter of the rollers, a given distribution of the rollers, which means the distance between the centers of two adjacent rollers, and for a given depth of their immersion, as well as for a given or desired plastic deformation, it is possible to edit only one specific product mix or material assortment , which in each case depends on the appropriate thickness of the product and its yield strength. In order to make the right machines in this situation relatively flexible and adaptable to different types of products, in the state of the art it is known to use the right machines with interchangeable cassettes and different roller diameters.

Such a correct machine of the type mentioned above is known from EP 1584384 Bl. This document discloses a correct machine that contains a drive unit equipped with an engine and a main gearbox connected to it, and it is possible to attach interchangeable cassettes interchangeable to the main gearbox, of which each interchangeable cassette contains correct rollers of different diameters and a different number of correct rollers. In addition, the replaceable replaceable cassette with correct rollers having a small diameter has a separate intermediate gear integrated into the replaceable cassette, which is adapted to be connected with the main gear of the correct machine. At the same time, replaceable cassettes are used, each of which is equipped with a rigidly specified set of tools consisting of combinations of correct rolls and support rollers. In each case, replace the set of correct rolls and support rollers, available in the upper support frame or lower support frame. Thus, in the state of the art, replacement by means of a replaceable cassette, respectively, of complete sets of correct rolls and support rollers is known.

An alternative to replacing the complete set with a replaceable cassette is described in WO 2008/145355 A1. This document discloses replacing the correct rolls of the correct machine separately. If necessary, joint replacement of upper and lower pairs is possible.

In addition, sheet metal manufacturers are currently faced with the need to produce an extensive assortment of sheet metal or strips having a wide variety of sizes and rigidity, in batches of both small and large volumes. This entails covering a wide range of edits with the correct machines used for this. To enable coverage of a wide range of straightening, the correct machines require the use of different diameters of the correct rolls and / or different separation values (intervals) in order to achieve optimum straightening results. This can be achieved in principle with the help of correct machines with interchangeable cassettes, which are described, for example, in EP 1584384 A1, and which are equipped with suitably fixed sets of tools, i.e. fixed combinations of correct rolls and support rollers, however, do not provide flexibility appropriate to today's production conditions. However, in order to be able to rule, with the help of the correct machine, an extensive assortment of products of different size and rigidity, it is necessary to have in stock many different sets of interchangeable cassettes. In some cases it is necessary to keep even several correct machines in order to be able to optimally coordinate the requirements for each product being edited, i.e. to thin, medium or also to thick sheets of metal.

Therefore, there is, in addition, the need to improve the existing correct machines in relation to the range of edits they implement, i.e. the size of the products they process, and, in particular, also the need for an economical and fast retooling of machines.

Therefore, the basis of the invention is the task of creating such a solution that provides an improved ability to adapt the right machine to different requirements for editing, and to different ranges of editing.

For the correct machine of the type described in more detail above, this problem is solved according to the invention as a result of the fact that the set of correct rolls and support rollers located respectively in the upper and / or lower support frame is divided into a plurality of regular roll sections coordinated with each other in the form of modules each section is made in the form of a replaceable replaceable cassette, each of the correct roller sections contains at least one layer of support rollers and at least one corresponding to it rights il roll.

Preferred embodiments of the invention and expedient embodiments of the invention are the subject of the dependent claims.

Thus, according to the invention, a correct modular design tool (modular correct roll section) is provided inside the lower and / or upper cassette or the upper and / or lower support frame to provide an economical and quick conversion of the machines for extending or adapting the correcting machine's editing ranges. At the same time, the corresponding modular correct tool or the corresponding tool module consists of a modular section, which is made in the form of a replaceable replaceable cassette, each correct roll section containing at least one layer of support rollers and at least one corresponding correct roller. Thus, the corresponding regular roll sections form modular sections, each of which forms a tool module, with the upper and / or lower support frame being the tool carrier. This makes it possible to alternately equip the upper and / or lower support frame with a variable number of replaceable modular regular roller sections or tool modules, which consist respectively of combinations of correct rolls and support rollers having different diameters, separation, materials of the rolls and which are chosen in each case for optimal adaptation to the relevant editing tasks to be performed, in particular, to the relevant material being edited. It is possible to replace only individual modular correct roll sections, or also to replace all the correct roll sections of the support frame and, as a result, to re-equip the correct machine accordingly.

On the basis of the modular design, in addition, it is possible to implement in a correct machine a large number of different combinations of correct roll sections and, as a result, to create a substantially improved adaptability of the correct machine to different requirements for editing, and to different ranges of dressing. At the same time, by proper selection of the appropriate correct roller sections, it is also possible to significantly expand the general range of dressing of the correct machine with regard to the associated choice of the distribution of the diameters of the correct rolls into groups and is thus realized by their separation. There is also the possibility of picking the right machine, adapted to meet the desired technological requirements, through the skillful selection of the right rolls, actively participating in the dressing process, and improving, as a result, the quality of dressing. In cases when only one correct swath is worn with the correct machine, it is also possible to replace only the module containing this correct swath. In this case, there is no need to replace the entire set of the correct machine, which includes all the correct rolls.

Therefore, the picking of the correct machine can be made depending on the parameters of the sheet and the tool loading history, i.e. history of the impact of load on the correct rolls. During the straightening process, the individual correct rolls of the straightening machine are loaded to varying degrees, so that their service life is different during operation. In this case, it is possible to replace a particularly heavily loaded instrument. However, within the framework of the established replacement procedure, cyclic replacement of various modules of similar design at a certain position within the upper and / or lower support frame of the correct machine can also be performed.

Another advantage of the invention is that, according to him, in the correct machine it is necessary to replace only the smaller, also by weight, nodes. This allows you to work with cranes that have a lower capacity than those that would be necessary if you had to replace the entire set of the correct machine, containing all the correct rolls. Similarly, the footprint required for a separate modular correct roll section is smaller than for a full set of correct rolls. In addition, the low weight and smaller size of the modular correct roll section compared to a full set of correct rolls and / or support rollers also allows equipping centers for the supply of tools and their processing near the right machines.

In general, the invention provides the following advantages:

reduction of transport weight and overall dimensions of instrumental modules;

optimal configuration of the right tool for the product being edited;

combinations of correct rolls / support rollers with the possibility of expansion and adaptation to changes in the production program, processed using the correct machine;

reduction of investment costs compared to cassette-based solutions with the replacement of complete sets;

minimization of time spent on re-installation, thanks to the modular design of the correct rolls / support roller assemblies;

As a result of the cyclic replacement of the correct rolls / support rollers inside the cassette, it is possible to unify the service life / operating time of the tools.

In an embodiment, the invention provides that the correct roller sections, coordinated with each other in the form of modules, are made with the possibility of their replacement individually or in groups and are located in the upper and / or lower support frame. As a result, full, at least sufficient flexibility is ensured with respect to the positioning of the individual correct roll sections.

In order to equip the correct machine with the correct rollers in different positions with the possibility of their particularly flexible replacement, according to the embodiment of the invention, the advantage is that both the set of the correct rolls and the support rollers located in the upper support frame and the set of correct rolls and support rollers located in the lower support frame is located in the set of regular roller sections, each of which is coordinated with each other in the form of a module and made in the form of a replaceable replaceable cartridge.

In order to ensure good adaptation to the various requirements for dressing, and to different ranges of dressing, it is also advisable to divide the set of leveling rolls and support rollers, located respectively in the upper and / or lower support frames, into types of modular rolls and / or removable cassettes of the same or different size, which is also provided by the invention.

In addition, it is advisable to use different types of modular regular roller sections, so that the invention further provides that the set of regular rolls and support rollers, located respectively in the upper and / or lower support frames, is divided into types of modular regular roller sections and / or replaceable cassettes equipped with leveling rollers and / or support rollers in various ways regarding the respective diameters of the leveling rolls and / or support rollers and / or regarding the appropriate number of pr Avilny rolls and / or support rollers.

A particular advantage is achieved if the individual modular regular roller sections form respectively a replaceable cassette and are coordinated with each other so that they together constitute a system of replaceable cassettes formed from interchangeable replaceable cassettes. Therefore, in addition, the invention is characterized in that the individual modular straightening roller sections form, individually or in groups, interchangeable replaceable cassettes of a system of replaceable cassettes.

Such a system of interchangeable cassettes may include types of modular regular roller sections and / or interchangeable cassettes of a fixed size, which is also provided by the invention.

In this case, the system of replaceable cassettes may include types of modular leveling rolls and / or replaceable parts that are equipped with leveling rolls and / or support rollers in various ways regarding the respective diameters of the leveling rolls and / or support rollers and / or regarding the appropriate number of leveling rolls and / or support rollers, which is also a feature of the present invention.

Finally, in order to be able to record operating parameters and condition according to the degree of wear and determine, on the basis of this, the service life and the necessary replacement rolls for the correct rolls, the invention also provides that it contains means for recording and / or preserving the parameters of the material being edited and / or means for recording and / or saving process parameters acting on each of the modular correct roller sections during the dressing process, and / or state parameters set to zhdoy modular section after proper roll straightening process.

By regular roller sections, coordinated with each other in the form of modules, are meant respectively replaceable, complex elements of a regular machine, each of which forms a closed functional unit and in this respect forms a "modular regular roller section".

Below the invention is explained in more detail by example through the drawing. It shows:

FIG. 6 is a schematic representation of the construction of a straightening machine according to the invention with a work station for processing tools corresponding to it.

FIG. 1 shows a regular machine, generally designated by the symbol 1, which contains an upper support frame 2 and a lower support frame 3. In the upper support frame 2 there are three regular roll sections 4, 5 and 6 that are coordinated with each other in the form of modules, each the section is made in the form of a replaceable replaceable cassette, into which a set of regular rolls 7 and support rollers 8, located in the upper support frame 2, are divided. Three modular regular roll sections 4, 5, 6 are made identical in this embodiment, and each of them contains There are correct rolls 7 and support rollers 8 both in the same quantity and with identical diameters. In the modular correct roll section 4, the correct roll 2 'is located, in the correct roll section 5 - the correct roll 4', and in the correct roll section 6 - the correct roll 6 '.

In the lower support frame 3 are four regular roller sections 9, 10, 11 and 12, coordinated with each other in the form of modules, each section made in the form of a replaceable removable cassette. They, in turn, divided the set of correct rolls 7 and the support rollers 8, located in the lower support frame 3. In this case, the correct rolls 7 of the corresponding modular regular roller sections 9-12 also have the same diameter, and in each of the modular correct roller sections 9 -12 same number of them. Likewise, the modular regular roller sections 9-12 are equipped with support rollers 8 having respectively the same diameters and available in the same quantity. In this case, if it is necessary to make a replacement with respect to individual correct rolls 7 and supporting rollers 8 or several of them, it is possible to replace individual modules 4-6 and 9-12 and exchange them independently of each other. This makes it possible to adapt the correct machine 1 to the various requirements of the edit.

FIG. 1a is shown in schematic side view of the lower modular regular roller section 9, viewed in side view in the direction 40 of processing. You can see how each of the correct rolls 7 rests on several support rollers 8.

FIG. 2 shows the lower support frame 3, in which the modular flat roller sections 10 and 11 according to the embodiment of FIG. 1 are replaced with four regular roller sections 13-16 of half the width. Modular regular roller sections 13-16 are also formed identically to each other, however, they have rollers and rollers of much smaller diameters compared to regular roller sections 9 and 12.

On the left side of the image in FIG. The 2 dotted line shows that individual modules, modules 12 and 15 here as an example, can be replaced as part of a tool upgrade. However, it is also possible to replace several regular roll sections with groups, as shown in the middle part of FIG. 2 on the image shown by the dotted line. Dismantled the correct roll sections 13-16 replace the installed correct roll sections 17-19. On the right side of the image in FIG. 2 shows the cyclic replacement of individual modular regular roller sections 13-16. Here, the correct roll section 13 is removed, then the correct roll sections 14-16 are shifted in the lower support frame 3 to the correct roll section 9 to close the gap formed due to the removal of the correct roll section 13. Then the correct roll section 13 is inserted again into the gap formed after that on the side of the correct roll section 12. Thus, it is possible to bring the individual correct roll sections 13-16 into positions that, when straightening the sheet material carried through the correct machine, are subjected different mechanical loads. As a result, it is possible to achieve uniform wear of the correct rolls 13-16 of the correct roll sections.

FIG. 3 shows by way of example several possible combinations of different modular leveling roller sections 9-21 in their location on the lower support frame 3. In a similar manner in FIG. 4 shows in the schematic diagram various locations and combinations of modular regular roller sections 4-6 and 22-30 in the upper support frame 2.

From figures 3 and 4 it can be seen that it is possible not only to combine rollers and / or rolls of different sizes in any way, but also to vary the separation values (center-to-center distances) depending on the selection of pairs.

Separate regular roll sections may also not vertically move vertically relative to the sheet material passing through the correct machine so that they are not continuously in mechanical contact with the sheet material being processed, as is essentially known from the processing of the sheet metal by means of correct machines. Thus, it is possible to vary the respectively active number of the correct rolls 7, without the need to replace the individual modular correct roll sections.

FIG. 5 schematically shows how the processing of the recorded parameter of the “actual diameter of the correct roll” state as well as the recorded parameters of the process “collection of information about the sheet of metal: temperature, strength, thickness” can be used in order to use the recorded data as well as the computing unit and a memory block, to receive automated auxiliary information and notifications, on the one hand, on whether the correct combination of tools is installed, i.e. in this case, a combination of modular regular sections, necessary to achieve the desired result of the editing, and its availability, as well as whether the necessary parameters of the state, for example, a sufficient diameter of the correct rolls, also take place for these sections. sheet, and in the event that the existing combination of modular regular roller sections is determined to be insufficient or inappropriate, replace the tool or change the individual modular correct roller sections. Only after this begins the process of editing the sheet.

FIG. 6 shows a schematic view of the construction of a leveling machine 1 according to the invention with a corresponding drive 31 of the correct rolls, which contains the main drive 32 and the main gearbox 33, as well as the drive mechanisms 34. A tool processing station 35 is located opposite the drive 31 of the correct rolls , which contains a grinding machine 36, a supply of modular leveling roller sections with sets of 37 leveling rolls, as well as tool production with a rail track 38 for a crane.

Modular regular roller sections 4-6 and 9-30 are matched with each other in the form of modules along their width 43, 44 relative to the width 41 of the coverage of the lower support frame 3, measured in the machining direction 40 of the sheet metal being machined, or to the width 42 of the coverage of the upper support frame 2, depending on the place of their insertion in the upper support frame 2 or in the lower support frame 3, so that in the position determined by the corresponding width 43, 44 of each of them or a width multiple of the corresponding width 43, 44, it is possible to place one respectively modularly correct roll section or several modular correct roll sections. In this case, in cases where a certain position must be left free, it is also possible, of course, to place the corresponding nodes there, which are not equipped with correct rolls 7.
