Description

Device for mounting a module on a frame of a rolling mill

Technical Field

The utility model relates to a device for inciting somebody to action module installation is in the frame of rolling mill.

Background

From the prior art (for example EP 1753555B 1), it is known to mount rolling accessories in the form of structural units to the stands of a rolling mill. Such a structural unit is also referred to as a "module" in the rolling mill. In this case, it can be provided that an inlet-side module and an outlet-side module are respectively mounted on the inlet side and the outlet side of the rolling mill. The fixing of the modules on the stands of the rolling mill chosen for this purpose has the disadvantage that it is very complex and therefore time-consuming, in particular in a renovation project.

SUMMERY OF THE UTILITY MODEL

The object of the invention is therefore to optimize the installation of modules in the frame of a rolling mill.

The above task is achieved by a device for mounting a module on a stand of a rolling mill.

The device according to the invention is used for mounting a module, for example a structural unit formed by a rolling attachment or a plurality of rolling attachments, on a stand of a rolling mill with its lateral orientation preferably in the horizontal direction towards the centre of travel of the strip. Such a device comprises at least one wedge element which can be arranged between a stop face of the frame and a contact face of the module. The wedge members are movable parallel to the direction of conveyance of the material moving through the mill. The wedge element has a base surface extending parallel to the conveying direction and a wedge surface arranged at an angle to the base surface, so that the lateral distance of the module from the center of travel of the strip can be varied or adjusted to a predetermined value by moving the wedge element parallel to the conveying direction.

In this connection, it should be separately pointed out that, in the sense of the present invention, the characteristic "strip travel" is the direction of movement of the material actually through the rolling mill. The material may be endless metal strip. But the material may also be a metal plate of limited length.

The utility model discloses based on following basic discovery: due to the movability of the wedge elements parallel to the conveying direction, the positioning of the modules on the stand of the rolling mill with respect to the lateral distance from the center of travel of the strip can be adjusted. In other words, by moving the wedge elements parallel to the conveying direction, a target position of the modules relative to the "actual" position of the strip travel and therefore of the rolled stock in the plant or rolling mill can be achieved, in which the modules are at a predetermined lateral distance from the center of the strip travel. After the module has reached the desired position of travel relative to the strip, the module is mounted or fastened to the frame by means of the device according to the invention, and the wedge-shaped element is clamped between the frame and the module here.

The use of the invention is particularly advantageous in the following cases: the stands of the rolling mill or the corresponding uprights of the stands of the rolling mill are not ideally directed vertically upwards, but are for example inclined slightly sideways (outwards or inwards) at their upper ends. In this case, the brackets are not parallel to each other, but the module can still be mounted to such a frame by means of the device according to the invention.

The above-mentioned lateral displacement of the module, which occurs in the case of a movement of the wedge element parallel to the conveying direction, is achieved by the configuration of the wedge element and its spatial position: the orthogonal lines of the bottom surfaces of the wedge elements extend on the one hand approximately horizontally and on the other hand also transversely to the conveying direction.

With the device according to the invention, it is possible to mount or fasten the module on the frame appropriately even in a case where, for example, the bracket on the operating side is tilted outward and the bracket on the driving side is also tilted outward, but the tilt angle is different from that of the operating side. Alternatively, the module may be mounted to the rack as well if one of the brackets on the drive or operating side is angled outwardly or inwardly and the other bracket (i.e., the operating or drive side) is correspondingly angled to the opposite side. In any case, this tilting of the bracket is compensated for by clamping and fixing the wedge-shaped element at the upper and lower edges of the module at different positions between the module and the adjacent rack, respectively.

As mentioned above, the bottom surface of the wedge member is angled with respect to the wedge surface. In view of the fact that when the wedge element is received between the frame and the module when the module is mounted to the frame of the rolling mill, the wedge surface of the wedge element is in contact with the contact surface of the module, it is advantageous for the invention that the contact surface of the module is complementary to the wedge surface of the device. In the sense of the present invention, this means that the contact surfaces are constructed or oriented in the same way at an angle, i.e. in the present case at an angle relative to the conveying direction, which angle is equal to the angle between the bottom surface of the wedge element and the wedge surface.

In an advantageous embodiment of the invention, the orthogonal line aligned with the base surface of the wedge element extends transversely to the conveying direction.

In an advantageous embodiment of the invention, the wedge element can be provided with at least one through-opening, which is parallel to an orthogonal line of the bottom surface of the wedge element. Advantageously, two such through-holes are also formed in the wedge element. In this connection, it is understood that screws or screw connections can be accommodated in such through-holes, by means of which the module can be fixed to the frame of the rolling mill.

In this connection, it is to be pointed out separately that the above-mentioned movement of the wedge-shaped element parallel to the direction of transport occurs only when the module is newly fixed or mounted to the stand of the rolling mill, or when it is necessary to change the position of the module on the stand (in the case of unscrewing the screw connection) and thus the distance between the module and the centre of travel of the strip. This means that the wedge-shaped element is firmly fixed to the frame or is displaceably received or clamped between the frame and the module when the module is fixed to the frame, for example by a screw connection. This in turn means that the wedge elements can be moved parallel to the transport direction in the manner described above when the fixing of the modules on the stand of the rolling mill is released, for example in the form of a screw connection.

In an advantageous embodiment of the invention, the wedge element can be provided in such a way that an end plate with a lateral projection is arranged adjacent to the base surface or wedge surface. With such an end plate and its lateral projections the wedge-shaped element is made easier to move parallel to the conveying direction. For example, when it is desired or required to adjust horizontally the lateral position or lateral distance of the module relative to the centre of the rolling mill, suitable mounts (e.g. mobile hydraulic cylinders or the like) may be connected or fixed to the lateral projections of the end plates to effect movement of the end plates parallel to the conveying direction.

In an advantageous development of the invention, the device can also be provided with a feather key, which is arranged on the bottom side of the module. Such a feather key serves to support the module, in particular on the base or on a surface located below the module. The appropriate dimensions of the feather key in the vertical direction and its height therefore also determine or influence the vertical positioning of the modules with respect to the stand of the rolling mill on which they are fixed.

The installation of the modules on the stand of the rolling mill can also be simplified in that the device is provided with a stop plate by means of which the modules can be fixed on the inlet side or on the outlet side of the stand of the rolling mill. Such a stop plate can be provided or arranged on an end face of the module, for example.

The modules that can be mounted or fixed to the stand of the rolling mill by means of the device according to the invention are preferably inlet-side modules and/or outlet-side modules. The inlet side module is fixed to the inlet side of the stand of the rolling mill, corresponding to its name. The outlet-side module is fixed, mutatis mutandis, to the outlet side of the stand of the rolling mill.

By means of the invention, it is possible to mount or fix modules to the frame of a rolling mill with low costs and short or shortened assembly times. By moving the wedge-shaped elements parallel to the direction of transport, the lateral distance of the modules from the centre of travel of the strip can be varied or adjusted to compensate for possible orientation errors of the rolling mill and the corresponding stands.

The utility model discloses specially adapted single frame equipment or many frame equipment (for example serial-type production line).

Detailed Description

In the following, a preferred embodiment of the invention will be described with reference to fig. 1 to 9, in which the modules can be mounted to the frame 1 of the rolling mill W by means of respective devices 10. In the drawings, like features are each denoted by like reference numerals. In this connection, it is separately noted that the figures are merely simplified and, in particular, are not shown to scale.

Fig. 1 shows a simplified side view of a rolling mill W and a corresponding stand 1 on which modules 12 are fixed by means of a device 10 according to the invention, which will be explained in more detail below.

In fig. 1, the direction of conveyance is denoted by "T", along which the material, preferably a metal strip or sheet, is moved through the rolling mill W. This also applies in the same way to fig. 5 and 6.

Fig. 2 and 3 show the module 12 from fig. 1 in a front view and a top view.

In this connection, it should be pointed out separately that the module 12 is a structural unit in the sense of the present invention, with which a plurality of rolling attachments are combined. These rolling accessories may include, in particular: a spray beam, a splash wall, a cleaning beam, a cooling beam, strip deflectors for the upper and lower working rolls of the rolling mill, strip data measuring devices, strip tension measuring rolls, protection devices for strip thickness measuring devices, fixed strip guide tables and/or strip pressure rolls with integrated strip cooling.

Fig. 4 shows a perspective rear view of the module 12. The module 12 shown here can be an inlet side module which is correspondingly mounted or fixed on the inlet side of the stand of the rolling mill.

In order to fix the module 12 to the stand 1 of the rolling mill W, the device 10 comprises a plurality of wedge elements, which are respectively designated by the reference numeral 14 in the representation of fig. 4. Two wedge-shaped elements 14 are provided on each side of the module 12, i.e. on its upper and lower edges, respectively.

On the end faces of the two vertical legs or uprights of the module 12, respectively, stop plates 27 are mounted, by means of which the module 12 can be fixed on the inlet side of the frame. In this respect, it is separately noted that for the sake of simplicity, the holes for fastening are not shown in the illustration of fig. 4.

To further illustrate the manner in which the fastening device 10 according to the present invention operates, fig. 5 shows a cross-section of a corresponding wedge-shaped element 14, which is mounted on the upper edge of the module 12. The dotted line "20" in fig. 5 indicates the center of the rolling mill W. The details are described below with respect to FIG. 5:

a wedge element 14 is accommodated between the frame 1 and the module 12 fixed to the frame. As also shown in fig. 6a, the wedge element 14 comprises a bottom surface 18 and a wedge surface 19 extending at an angle a to the bottom surface.

The arrangement of the wedge elements 14 relative to the frame 1 or the modules 12 is to be understood such that a line O orthogonal to the base surfaces 18 of the wedge elements is arranged extending horizontally on the one hand and transversely to the conveying direction T on the other hand. Such orthogonal lines O are shown in the illustration of fig. 6, which shows a cross section of the wedge-shaped element 14 arranged at the lower edge of the module 12. The wedge member 14 of figure 6 operates in the same manner as the wedge member 14 of figure 5.

The modules 12 are fixed on the frame 1 or on the inside of the corresponding frame column, for example by screw connections. The inner side of the frame column 1 is designated by "2" in fig. 5 and 6, respectively, and serves as a stop surface with which the underside 18 of the wedge element 14 comes into contact when the wedge element is received or clamped between the frame 1 and the module 12 fixed thereto.

The screw connections can be arranged at two different positions above or below the wedge element 14 and are each indicated in fig. 5 for simplicity by the dashed line "22". Alternatively, it is also possible to form a through-hole in the wedge element 14 at the location of the screw connection. In this case, screw connections or corresponding screws are passed through the through-holes to fix the module 12 to the frame upright 1.

The module 12 has a contact face 16 adjacent the wedge element 14 which is configured to complement the inclination or direction of the wedge face 19. As illustrated, the wedge surface 19 of the wedge element 14 rests on the contact surface 16 of the module 12 when the wedge element 14 is located between the frame 1 and the module 12. The opposite bottom face 18 of the wedge element 14 laterally abuts against the inner side 2 or the stop face 2 of the frame 1 or its frame upright. Furthermore, it can be seen in fig. 5 that a stop plate 27 (see fig. 4) mounted on the module 12 abuts against the end face of the frame upright 1.

An end plate 24 having lateral projections 25 is mounted on one end face of the wedge member 14.

The utility model discloses the operation as follows:

during fastening or assembly of the module 12 to the frame 1, the wedge element 14 can be moved parallel to the transport direction T at least before the screw connection 22 is tightened. This is indicated in fig. 5 by the double arrow "P1". To move the wedge member 14 in this manner, a suitable actuator (e.g., in the form of a traveling hydraulic cylinder or the like) may be operatively engaged with the lateral projection 25 of the end plate 24.

By means of said wedge-shaped surface 19 of the wedge element 14 abutting against the contact surface 16 of the module 12, the module 12 is displaced laterally here by a displacement of the wedge element 14, which is indicated in the illustration of fig. 5 by the double arrow "P2". Thereby, the lateral distance a of the module 12 from the centre 20 of travel of the rolling mill W or strip can be varied. Relevant examples are as follows:

example 1:

in the illustration of fig. 5, if the wedge element 14 is moved or shifted in the conveying direction T, the module 12 "migrates" to the right, i.e. in the direction of the center 20 of the rolling mill W, the distance a is thereby reduced.

Example 2:

in the illustration of fig. 5, if the wedge element 14 is moved or displaced in the direction opposite to the transport direction T, the module 12 "migrates" to the left, i.e. away from the center 20 of the rolling mill W, the distance a thereby increases.

The above explanations and examples regarding the orientation of the wedge elements 14 between the frame 1 and the module 12 apply to all four wedge elements 14 shown in fig. 4, respectively.

After the respective wedge elements 14 have been oriented in the desired manner between the stand 1 and the module 12, in order to reach or adjust the desired distance a of the module 12 from the center 20 of travel of the rolling mill W or strip, the screw connection 20 is inserted and tightened. The individual wedge-shaped elements 14 are thereby firmly clamped between the frame 1 and the module 12. As shown in the illustration of fig. 5, the bottom surface 18 of the wedge element 14 rests against the inside 2 of the frame or of a frame upright thereof.

With regard to or in preparation for the reorientation of the module 12 relative to the frame 1 and/or the possible replacement of the module 12 with another module, it will be understood that it is necessary first to unscrew the screw connection 22 and then to reposition or remove the wedge element 14 from the module 12 (in the case of replacement of a new module). The wedge member 14 may then be moved in the direction of arrow P1 to orient the module 12 in the direction of arrow P2.

In order to adjust the vertical height at which the module 12 is fixed relative to the frame 1, the device 10 comprises at least one sliding key 26. Fig. 4 shows two such sliding keys 26, which are arranged on the bottom side of the module 12 on two sides or on two-sided columns, respectively. The feather key 26 is supported on a surface on or below the base. The vertical position or height at which the module 12 is fixed to the rack 1 is influenced here by suitable selection of the dimensions of the feather key 26 in the vertical direction or its height.

To further illustrate the module 12, it is shown in other views in fig. 7 to 9. As mentioned before, reference is made here to an inlet side module. In the perspective rear view of fig. 7, similarly to the illustration in fig. 4, four wedge elements used in the fastening of the module 12 to the rack 1 are respectively designated by 14.
