Definitions
- the invention relates to a control device for a distribution network of hydraulic and / or pneumatic operating media, in particular in rolling mill construction.
- the invention also relates to a media module with such a control device and a roll stand.
- Control elements (hereinafter jointly referred to as “control elements”) grant and enable their actuation, are mostly in a
- Panel design or column design implemented. They enable the operation and maintenance of a distribution network for liquid or gaseous media, such as lubricants and coolants, as well as hydraulic or pneumatic pressure media for actuators and drives.
- a distribution network for liquid or gaseous media such as lubricants and coolants, as well as hydraulic or pneumatic pressure media for actuators and drives.
- Such distribution networks with control device (s) are used in metal processing, in particular in rolling mill construction.
- the control elements can be clearly arranged, for example in functional groups, but since the position and location of the control elements are predetermined by the board level, the hydraulic / pneumatic connection of the same is considerable
- control blocks fall under the column design in which the control elements are arranged essentially vertically. This can be a stack of individual control blocks or a continuous control column to which the control elements are individually attached. Advantages of the column design are the smaller space requirements and a reduction in the piping compared to the panel design. Nevertheless, the piping effort is still considerable. This also applies to installation and maintenance work.
- the distribution network has pipeline groups and a central control station connected to the pipeline groups in a media platform of a rolling stand.
- Pipe routes are on the
- confined spaces can result in complex safety regulations. For example, it may be necessary to park a second person at the hatch outside the confined space in order to secure the maintenance person working in it, who may be roped up.
- One object of the invention is to improve the control of distribution networks of hydraulic and / or pneumatic operating media, particularly preferably in rolling mill construction, in particular by overcoming at least one of the disadvantages mentioned above
- the control device according to the invention is set up for a distribution network of liquid and / or gaseous media, in particular for use in metal processing plants.
- the control device is particularly preferably used in rolling mill construction.
- the control device is thus preferably a fluid control device and / or supply device in rolling mill construction.
- the control device for hot or cold rolling stands can be used for rolling steel or non-ferrous metals (non-ferrous metals).
- the distribution networks that can be connected to it transport operating media, such as lubricants and coolants, hydraulic and / or pneumatic pressure media for actuators, drives and the like.
- the function blocks can be installed on the base plate along two axes and the function blocks in turn have several sides, for example five cube sides, for connecting control elements, a large number of connections and branches can be made without additional connections and piping. This reduces the number of potential leakage points. This means that a more extensive supply can be provided with the base plate than is possible, for example, with a vertical control column or control panel.
- the control device is accordingly a modular assembly unit for fluid technology and piping technology.
- Installability and expandability the technical solution is space-saving and particularly low in piping. This strengthens the design and operational safety.
- the manufacturing requirements can be reduced, and the clarity of the control elements and functionality are increased. The maintenance effort is reduced.
- a targeted shutdown of selected functions is possible with a minimum of material and labor and without additional piping within the control device.
- the structure of the function blocks can also be standardized.
- the modular structure of the control device also allows the system to be dismantled in a container-friendly manner, which means that transport can be carried out quickly and efficiently without any heavy transport.
- Cooling lubricants, water and the like are less polluted.
- the cleaning effort is reduced.
- External piping can be omitted, as each function can be supplied with a pressure medium if it is internally drilled.
- any leaks that do occur can be assigned precisely to the functional block concerned, which means that precise maintenance and repairs can be carried out.
- Other, unaffected function blocks do not have to be dismantled and possibly also not shut down, which means that the system can continue to run in the latter case.
- the technical solution presented here also makes it possible to cover all conceivable fluids that can occur in the rolling mill, including the oil-air lubrication of the work roll bearings, and to distribute them in an orderly manner in the media module presented below.
- the base plate and / or an intermediate plate arranged between the functional blocks and the base plate preferably has several Openings which are set up for screwing the functional blocks by means of fastening screws, preferably lag screws.
- control elements preferably comprise valves and / or actuating elements thereof.
- the modular concept presented here allows a clear grouping of valves without increasing the piping effort.
- the media transport lines in the base plate preferably include one or more supply lines and one or more disposal lines that are set up to transport the corresponding media from a main supply to the functional blocks and from there to consumers such as actuators, adjusting cylinders, drives, etc. Since the supply line (s) and disposal line (s) run horizontally in the plane of the base plate, the piping of the function blocks can branch off directly from these upwards out of the plane of the base plate, whereby the piping effort is minimized.
- the media transport lines are preferably embedded at least in sections in the base plate, as a result of which the modularity and installability of the control device are further improved.
- the above-mentioned object is also achieved by a media module that is set up to operate a distribution network for liquid and / or gaseous media, in particular in rolling mill construction.
- operation here includes control, regulation, maintenance, monitoring and the like.
- the media module has one or more control devices in accordance with one or more of the embodiment variants set out above.
- the media module is particularly preferably implemented as a media stage.
- the media platform can be an open space with a safety railing and one or more entrances through which the maintenance personnel can enter the media platform, for example via a ladder, for example when the media platform is placed on a roll stand.
- the media module can, however, also be constructed in other ways.
- the media module can be a ground level control point with one or more control devices, an open or closed control room with one or more control devices and the like.
- the media module preferably also has an energy supply device.
- the energy supply device preferably has at least one pump and at least one media container for supplying one or more consumers.
- the energy supply device can include filters, fleece and / or cooling or the like.
- the media module has a pump station, which means that there is no need for an external energy supply, for example in the basement below the system, as well as lines and pipe routes there.
- the media module functions independently and is therefore particularly flexible and can be installed with a reduced workload.
- control device described here as well as the media module equipped with it, are particularly preferably used in the rolling mill, for example as part of a rolling stand.
- the above-mentioned object is also achieved by a roll stand with a media module in accordance with one of the embodiment variants set out above.
- the media module is preferably fastened to one or more roll stands of the roll stand, particularly preferably above rolls carried by the roll stands.
- the media module is preferably screwed onto the roll stands.
- the media module does not necessarily have to be placed on top of the stands of the roll stand, but can be attached to the vertical surfaces of the stands or stand posts on the operator side and drive side, preferably on the outside of the stand, but not necessarily exclusively there. In this way, the height of the media module can be chosen flexibly.
- the media module can be mounted decoupled from the roll stand, preferably on its own supports that are fastened in the foundation of the system, for example. This avoids vibrations and shocks in the mechanics, for example in the case of piercing processes or changes in tape thickness, from being introduced into the media module and thus into the sensitive valve technology.
- the level of the media module can be flexibly brought to the technologically optimal height to the consumers, since the media module, especially in the form of a media platform, can be "pulled” over the stand of the roll stand and fixed at any height.
- the ideal height of the media module for example based on empirical values or determined by simulation, allows the hydraulic and / or pneumatic paths to be kept short enough to ensure good dynamics between the control element (valve) and the element to be controlled (cylinder, motor, etc. .) to reach.
- the flat design of the control device makes it particularly suitable for installation on a media platform of a roll stand.
- the control elements with comparatively poor accessibility which are conventionally arranged on several levels due to the height of the control columns, are arranged in a clear and easily accessible manner in this way. Any pipelines that impede accessibility can be omitted.
- the stage height can be lower overall. By eliminating the need for tight hydraulic spaces and the work in them, work safety can be significantly improved. Any safety precautions and the associated costs can be reduced. Machine piping in the stand area and on the media platform can be significantly reduced by arranging the modular media platform itself as a module on the roll stand.
- the media platform can be arranged and fastened to the typically four upright posts of the rolling stand on the outside of the stand, which means that the pipelines from the control elements to the consumers can be shortened and, overall, significantly less piping work can be achieved.
- the laying and bundling of the control elements on the media platform saves the route from the center of the scaffolding to the upright posts as a piping route.
- supports for fastening the media platform can be flanged onto the uprights of the roll stand, which makes the media platform particularly special can be placed low.
- control elements on the consumers such as adjusting cylinders for the rollers
- a low overall height and a technologically very close installation location of the control elements on the consumers can be achieved without the maintenance personnel having to go into confined spaces directly to the consumers, for example climbing down from the media platform through a hatch.
- Sufficient freedom of movement and thus a gain in safety are always provided by the open design of a media platform equipped with the control devices.
- Due to the low design of the media platform, all control elements can also be arranged centrally on the media platform, as the hydraulic / pneumatic path lengths are kept short.
- the exact positions of the control device (s) and media platform can be determined by simulation so that the dynamics between the control valve and the consumer are optimally set.
- the reduction in the amount of piping also leads to a lower weight of the overall system, which contributes to an increase in efficiency both during installation and operation. Together with the comparatively low construction, the system and the associated hall size, etc., can be more compact. The costs and labor for the manufacture and assembly of the connecting pipelines on the construction site can be reduced. This is further supported by any integration of the energy supply device.
- the media module in particular in the embodiment of the media stage, can include further functions.
- the media module can also be used as a carrier for other elements that originally belong to the mechanics of the roll stand.
- a hoist can be integrated or attached to the media module in order to transport loads, for example for maintenance of the roll stand.
- a step wedge and / or stop means or assembly points for attaching stop means can be provided, which can be used for assembly or maintenance work in the roll stand.
- the media module can have an integrated step plate pull-out device.
- Stand crossbars can be integrated on the media module, which in turn can be used as carriers of various functions. If the stand crossbars are designed as hollow beams, they can function synergistically, for example, as a suction duct, water connection and / or distributor pipe for roller cooling in hot strip systems. Furthermore, safety devices such as fire extinguishing devices can be integrated in the media module.
- FIG. 1 is a schematic cross-sectional view of a control device for a distribution network of liquid and / or gaseous operating media.
- FIG. 2 is a perspective view of an exemplary control device with a plurality of functional blocks.
- FIG. 3 is a perspective view of a media module set up as a media platform with control devices on a roll stand.
- FIG. 4 is a perspective view of a media module set up as a media platform with a reduced structure and a base plate shown transparently.
- FIG. 5 is a perspective view of a media module set up as a media platform, equipped with a power supply device.
- the control device 10 has a base plate 11 and a plurality of functional blocks 12 which can be mounted on the base plate 11 and detached therefrom by means of fastening screws 13 (only shown schematically in FIG. 1 by their center lines).
- the base plate 11 is preferably penetrated by a plurality of bores (not shown in the figures for the sake of clarity), which allow a flexibly configurable arrangement of functional blocks 12.
- a function block 12 for maintenance and / or repair purposes is shown raised. It should be pointed out that the function blocks 12 do not necessarily have to be designed in the shape of a cube or cuboid, even if this can be advantageous with regard to any standardization.
- the base plate 11 is to be arranged essentially horizontally and leads in its plane one or more media transport lines 11a of a distribution network for liquid and / or gaseous operating media, such as lubricants and coolants, hydraulic and / or pneumatic pressure media for actuators, drives and the like.
- the media transport lines 11a include, for example, supply, discharge and / or distribution lines.
- Supply lines and disposal lines (for example P, T, X, Y, A, B connections) are particularly preferably included and embedded in the base plate 11, which carry the corresponding media from a main supply to the function blocks 12 and back in the direction direct the customer.
- the main supply and the individual consumers are not shown in the figures.
- the function blocks 12 can be installed on the base plate 11 along two axes and the function blocks 12 in turn have multiple sides, For example, have five cube sides for connecting control elements 12b, a large number of connections and branches can be made without additional connections and piping. Any leakage points are thus reduced. With the base plate 11 as the basis and the configurable function blocks 12, a more extensive supply can thus be provided than is possible, for example, with a vertical control column or control panel.
- a detailed exemplary structure of a control device 10 with a multiplicity of function blocks 12 is evident from the perspective illustration in FIG.
- the functional blocks 12 are preferably modular and applicable, i. E. With prefabricated and / or preconfigured function blocks 12, a large number of hydraulic / pneumatic interconnections can be implemented.
- FIG. 2 shows a control device module, which can also be referred to as a “control plate”, with a base plate 11 and a large number of functional blocks 12 screwed onto it.
- the media module 1 designed as a media platform, is shown in a perspective view from above, the media module 1 being shown in a reduced structure and the base plate of the same being shown transparently in order to connect supply lines such as supply, discharge and / or distribution lines to make visible for a distribution network of the roll stand 2.
- the media module 1 is preferably screwed to the roll stands of the roll stand 2.
- the media module 1 can be mounted decoupled from the roll stand 2, preferably on separate supports that are fastened in the foundation of the system, for example. This avoids vibrations and
- the media module 1 Vibrations of the mechanics, for example during piercing processes or changes in tape thickness, are introduced into the media module 1 and thus into the sensitive valve technology.
- the media module 1 can also be placed on or attached to supports of any other media modules, such as, for example, side wall modules. These other media modules or
- the level of the media module 1 can be flexibly brought to the technologically optimal height to the consumers, since the media module 1, in particular in the form of a media platform, can be "pulled” over the stand of the roll stand and fixed at any height .
- the ideal height of the media module 1 for example determined based on empirical values or by simulation, makes it possible to keep the hydraulic and / or pneumatic paths sufficiently short in order to optimize the dynamics.
- a second level with saddlebags is not required to place the media stage on the stand and at the same time to get as close as possible to the critical consumers. This eliminates the need for the operating staff to have to climb back and forth between two levels on a ladder to access the controls.
- the media module 1 comprises a pump station, which means that there is no need for an external energy supply, for example in the basement below the system, as well as lines and pipe routes there.
- the media module 1 is self-sufficient and therefore particularly flexible to use and installable with reduced workload.
- the control device 10 described here, as well as the media module 1, which has one or more such control devices 10, are assembly units of fluid technology and piping technology with a modular structure on several levels.
- the technical solution is space-saving and particularly low in piping. This strengthens the design and operational safety.
- the manufacturing requirements are reduced, and the clarity of the control elements 12b and the functionality are increased.
- the maintenance effort is reduced.
- a targeted shutdown of selected functions is possible with a minimum of material and labor and without piping within the control device 10.
- the structure of the function blocks 12 can also be standardized.
- the modular structure also allows the system to be dismantled in a container-friendly manner, which means that transport can be carried out quickly and in a resource-efficient manner without heavy transport.
- an intermediate plate can be inserted between the functional blocks 12 and the base plate 11, which serves to fasten the functional blocks 12 or supports them.
- the complexity of the bores in the base plate 11 can thus be reduced, since the screw connection bores and the connection lines of the relevant functional block 12 can thus be adapted to the base plate 11.
- Fastening screws 13, which are preferably implemented as strong lag screws, in this case connect the base plate 11 and the intermediate plate without leaks.
- a collecting device, such as a tub, can be provided for any residual leakage that may occur.
- the control device 10 described herein, as well as the media module 1 equipped with it, are preferably used in metal processing, particularly preferably in particular in rolling mills. Because of the flat design, the control devices 10 are particularly suitable for hydraulic controls that are arranged on a media platform. The media platform can be arranged above the roll stand.
- the control elements with comparatively poor accessibility, which are conventionally arranged on several levels due to the height of the control columns, are arranged in a clear and easily accessible manner in this way. Any pipelines that impede accessibility can be omitted.
- the stage height can be lower overall. By eliminating the need for tight hydraulic spaces and the work in them, work safety can be significantly improved. Any safety precautions and the associated costs can be reduced.
- Machine piping in the stand area and on the media platform can be significantly reduced by arranging the modular media platform itself as a module on the roll stand 2.
- the media platform can be arranged and fastened to the typically four upright posts of the roll stand 2 on the outside of the stand, so that the pipelines from the control elements 12b to the consumers can be shortened and, overall, a significantly lower amount of piping can be realized.
- the laying and bundling of the control elements 12b on the media platform saves the route from the center of the scaffolding to the upright posts as a piping route.
- the media module 1 in particular in the embodiment of the media platform according to FIGS. 3 to 5, can include further functions.
- the media module 1 can also be used as a carrier for other elements that originally belong to the mechanics of the roll stand 2.
- a lifting device can be integrated or attached to the media module 1 in order to transport loads, for example for maintenance of the roll stand 2. It can be a step wedge and / or sling or
- Stand traverses can be integrated on the media module 1, which in turn can be used as carriers of various functions.
