Description

The invention relates to a device for attaching a module to a stand frame of a roll stand.

According to the state of the art (e.g. from EP 1 753 555 B1 ) it is known to attach rolling fittings in the form of a structural unit to a stand frame of a roll stand. Such a unit is also referred to as a "module" in connection with roll stands. It can be provided that an inlet side module or an outlet side module is attached to the inlet side and the outlet side of a roll stand. The attachment of modules selected for this purpose to the stand frame of a rolling stand is subject to the disadvantage that it is complex, which is time-consuming, in particular in the case of conversion projects.

Accordingly, the object of the invention is to optimize the attachment of a module to a stand frame of a roll stand.

The above object is achieved by a device for attaching a module to a stand frame of a rolling stand with the features of claim 1. Advantageous developments of the invention are defined in the dependent claims.

A device according to the present invention is used to attach a module, for example a structural unit formed from a rolling armature or a plurality of rolling armatures, to a stand frame of a rolling stand and to align it laterally, preferably in a horizontal direction toward the center of the strip run. Such a device comprises at least one wedge element, which can be arranged between a stop surface of the stand frame and a contact surface of the module. The wedge element can be parallel to a transport direction in which material is moved through the roll stand, be moved. The wedge element has a base surface running parallel to the transport direction and a wedge surface arranged at an angle to it, such that by displacing the wedge element parallel to the transport direction, a lateral distance of the module from the center of the belt run can be changed or can be set to a predetermined value .

At this point, it is pointed out separately that in the sense of the present invention the feature "strip travel" is the direction in which material is actually moved through the roll stand. This material can be endless strips of metal. However, this material can also be metal sheets that have only a limited length.

The invention is based on the essential finding that, due to the displaceability of the wedge element parallel to the direction of transport, it is possible to adjust the positioning of the module on the stand frame of a rolling stand with regard to a lateral distance from the center of the belt run. In other words, by moving the wedge element parallel to the direction of transport, a targeted position of the module relative to the strip run and thus to the "real" position of the rolling stock within the system or the roll stand, in which the module is at a predetermined lateral distance from the center of the strip run, is achieved occupies or has. After a desired position with respect to the belt run is reached for the module, the module is attached or fastened to the stand frame by means of the device according to the invention, and the wedge element is clamped between the stand frame and the module.

The use of the present invention is particularly advantageous in the event that the stands of a roll stand or the associated spars of the stand frame of a roll stand do not ideally point vertically upward, but, for example, with their upper end slightly to the side (to the outside or are tilted inwards. In this case, the stands are not aligned parallel to one another, but the module can nevertheless be attached to such a stand frame with the aid of the device according to the invention.

The above-described lateral displacement of the module, which occurs when the wedge element is displaced parallel to the transport direction, is achieved by the formation of the wedge element and its spatial position: an orthogonal, which is directed to a base area of the wedge element, runs on the one hand approximately horizontally and on the other hand also across the direction of transport.

With the aid of the device according to the invention, it is possible to suitably attach or fasten a module to a stand frame, also in the event that, for example, the stand on the operating side is tilted outwards and the stand on the drive side is also turned outward, but in one angle other than on the operating side. Alternatively, a module can also be attached to a stand frame in the event that one stand on the drive or operating side tilts outwards or inwards and the other stand (i.e. on the operating or drive side) tilts to the opposite side. In any case, such a tendency of the stands to tilt is compensated for by wedging the wedge elements on the upper and lower edges of the module in different positions between the module and the adjacent stand frame and fastening them there.

As already mentioned above, the base surface and the wedge surface of the wedge element form an angle between them. In view of the fact that the wedge surface of the wedge element comes into contact with the contact surface of the module when the module is mounted on a stand frame of a rolling stand, when the wedge element is received between the stand frame and the module, it is advantageous for the present invention to if the contact surface of the module is complementary to the wedge surface of the device. For the purposes of the present invention, this means that the contact area in the same way in is formed or oriented at an angle, namely in the present case at an angle with respect to the transport direction, which is identical to the angle between the base surface and the wedge surface of the wedge element.

In an advantageous development of the invention, the wedge element can be provided with at least one through hole which runs parallel to the orthogonal, which is directed towards the base of the wedge element. Advantageously, two such through holes are also formed in the wedge element. In this regard, it goes without saying that a screw or screw connection can be accommodated in such a through-hole, by means of which the module is fastened to the stand frame of a rolling stand.

At this point, it is pointed out separately that the aforementioned shifting of the wedge element parallel to the transport direction only takes place if the module is newly attached to the stand frame of a roll stand or if a position of the module on the stand frame - with loosened Screw connection - is to be changed in order to achieve a changed distance between the module and the center of the belt run. This means that the wedge element is firmly attached to the stand frame or is immovably received or clamped between the stand frame and the module when the module is attached to the stand frame, e.g. by means of screw connection. This in turn also means that the wedge element can be displaced parallel to the transport direction in the manner mentioned when the module is detached from the stand frame of a roll stand (for example in the form of a screw connection).

In an advantageous development of the invention, it can be provided for the wedge element that an end plate is arranged adjacent to the base surface or wedge surface, which has a lateral projection. Such an end plate and its lateral projection make it easier to move the wedge element parallel to the transport direction. For example, suitable ones Assemble mounting means (for example mobile hydraulic cylinders or the like) on the lateral projection of the end plate in order to achieve a displacement of the end plate parallel to the transport direction if this is to adjust a lateral position or a lateral distance of the module horizontally to the center of the roll stand is desired or required.

In an advantageous development of the invention, a feather key can also be provided for the device, which is arranged on an underside of the module. Such a key serves the purpose of supporting the module in particular on a surface or on a surface located below the module. A suitable dimension of the feather key in the vertical direction or its height thus also determines or influences a vertical positioning of the module relative to the stand frame of a roll stand to which the module is attached.

The assembly of the module on a stand frame of a roll stand can be facilitated if a stop plate is provided for the device, with which the module can be attached to the inlet or outlet side of a stand frame of a roll stand. For example, such a stop plate can be provided or arranged on an end face of the module.

The module, which can be attached or fastened to a stand frame of a roll stand by means of a device according to the present invention, is preferably an inlet side module and / or an outlet side module. In accordance with its name, an inlet side module is attached to the inlet side of a stand frame of a roll stand. Mutatis mutandis, an outlet side module is attached to the outlet side of a stand frame of a roll stand.

With the help of the present invention it is achieved that a module can be attached or fastened to a stand frame of a rolling stand with little effort and a short or shortened assembly time. By moving the wedge element parallel to the transport direction, a lateral distance to the center of the belt run can be changed or set for the module in order to compensate for any existing misalignments of the roll stand and the associated stands.

The present invention is particularly suitable for use in single-stand systems or in multi-stand systems (for example tandem lines).

Below is with reference to the Fig. 1-9 a preferred embodiment of the invention is explained, in which a module can be attached to a stand frame 1 of a roll stand W by means of an associated device 10. The same features in the drawings are provided with the same reference numerals. At this point, it is pointed out separately that the drawings are only simplified and in particular are shown without a scale.

Fig. 1 shows in simplified form a side view of a roll stand W and an associated stand frame 1, to which a module 12 is fastened by means of the device 10 according to the invention, which will be explained separately below.

In the Fig. 1 is a transport direction along which a material, preferably a metallic strip or sheet, is moved through the roll stand W, denoted by "T". This also applies to 5 and 6 .

The 2 and 3 show module 12 of Fig. 1 in an end view or in plan view.

At this point, it is pointed out separately that module 12 in the sense of the present invention is a structural unit with which a plurality of rolling fittings are combined. These rolling valves can include: Hold-down roll with integrated belt cooling device.

Fig. 4 shows a perspective rear view of the module 12. The module 12 shown here can be an inlet side module that is correspondingly attached or fastened to an inlet side of a stand frame of a roll stand.

To fasten the module 12 to the stand frame 1 of the roll stand W, the device 10 comprises a plurality of wedge elements, which are shown in the illustration of FIG Fig. 4 are each attracted by the reference numerals "14". Two wedge elements 14 are provided on each side of the module 12, namely on an upper and lower edge thereof.

Stop plates 27 are attached to the end faces of the two vertical legs or spars of the module 12, by means of which the module 12 can be fastened to the inlet side of a stand frame. In this regard, it is pointed out separately that in the representation of Fig. 4 to simplify the holes for attachment are not shown.

To further clarify the mode of operation of the fastening device 10 according to the invention, FIG Fig. 5 a section through an associated wedge element 14 which is attached to an upper edge of the module 12. In the Fig. 5 the dash-dotted line "20" indicates a center of the roll stand W. For Fig. 5 now the following explanations:
The wedge element 14 is received between the stand frame 1 and the module 12 attached to it. As in the Fig. 6a illustrated, the wedge element 14 comprises a base surface 18 and a wedge surface 19 extending at an angle α thereto.

The arrangement of the wedge element 14 in relation to the stand frame 1 or the module 12 is understood in such a way that an orthogonal O, which is directed onto the base surface 18 of the wedge element, runs horizontally on the one hand and is arranged transversely to the transport direction T on the other hand. Such an orthogonal O is in the representation of Fig. 6 shown a section through one at the bottom Edge of the module 12 arranged wedge element 14 shows. The functioning of the wedge element 14 from Fig. 6 corresponds identically to that of the wedge element 14 of FIG Fig. 5 .

The module 12 is fastened, for example, by means of screw connections to the stand frame 1 or to an inside of an associated stand spar. Such an inside of a column 1 is in 5 and 6 tightened in each case with "2" and serves as a stop surface with which the base surface 18 of the wedge element 14 comes into contact when it is received or clamped between the stand frame 1 and the module 12 attached to it.

The screw connection mentioned can be provided at two different points above or below the wedge element 14 and is in the Fig. 5 each symbolized by dash-dotted lines "22". As an alternative to this, it is also possible for through holes to be formed in the wedge element 14 at the locations of the screw connection. In this case, the screw connections or the associated screws are then passed through the through bores for fastening the module 12 to the upright 1.

Adjacent to the wedge element 14, the module 12 has a contact surface 16 which is complementary to the inclination or orientation of the wedge surface 19. If the wedge element 14 is, as explained, between the stand frame 1 and the module 12, the wedge surface 19 of the wedge element 14 rests on the contact surface 16 of the module 12. The opposite base surface 18 of the wedge element 14 lies laterally on the inside 2 or stop surface 2 of the stand frame 1 or of its stand spar. Furthermore, in the Fig. 5 to recognize that the stop plate 27 attached to the module 12 (cf. Fig. 4 ) abuts an end face of the upright 1.

An end plate 24, which has a lateral projection 25, is attached to an end face of the wedge element 14.

The invention now works as follows:
In the course of fastening or assembling the module 12 to the stand frame 1, at least before the screw connections 22 are tightened, the wedge element 14 can be moved parallel to the transport direction T. This is in the Fig. 5 symbolized with the double arrow "P1". For the purpose of displacing the wedge element 14 in this way, a suitable actuator, for example in the form of a mobile hydraulic cylinder or the like, can be brought into active engagement with the lateral projection 25 of the end plate 24.

Thanks to the explained wedge surface 19 of the wedge element 14, which rests on the contact surface 16 of the module 12, a displacement of the wedge element 14 means that the module 12 moves laterally, which in the illustration of FIG Fig. 5 is symbolized by the double arrow "P2". In this way, a lateral distance A of the module 12 from the center 20 of the roll stand W or the strip run can be changed. The following examples:

Example 1:

If in the representation of Fig. 5 the wedge element 14 is moved or shifted in the transport direction T, the module 12 "moves" to the right, ie in the direction of the center 20 of the roll stand W, as a result of which the distance A then decreases.

Example 2:

If in the representation of Fig. 5 the wedge element 14 is moved or displaced in the opposite direction to the transport direction T, the module 12 "moves" to the left, ie away from the center 20 of the roll stand W, as a result of which the distance A then increases.

The above explanations and examples for aligning a wedge element 14 between the stand frame 1 and the module 12 are understood in each case for all of the four wedge elements 14 shown in the illustration of FIG Fig. 4 are shown.

After a respective wedge element 14 has been aligned in the desired manner between the stand frame 1 and the module 12 in order to achieve or set a desired distance A between the module 12 and the center 20 of the roll stand W or the strip run, the screw connections 20 are inserted or tightened. As a result, a respective wedge element 14 is then firmly clamped between the stand frame 1 and the module 12. According to the representation of Fig. 5 the base surface 18 of a wedge element 14 lies against the inside 2 of the stand frame or from its stand member.

With regard to or in preparation for realigning the module 12 in relation to the stand frame 1 and / or for a possible replacement of a module 12 with another module, it goes without saying that the screw connections 22 mentioned must first be loosened, after which the wedge elements 14 are either repositioned or removed from the module 12 (in the case of replacement with a new module). The wedge elements 14 can then be displaced in the direction of the arrow P1 in order to align the module 12 in the direction of the arrow P2.

To set a vertical height at which the module 12 is fastened relative to the stand frame 1, the device 10 comprises at least one feather key 26. In the illustration of FIG Fig. 4 Two such feather keys 26 are shown, each of which is arranged on an underside of the module 12 on both sides or spars thereof. The feather keys 26 are supported on a surface or a surface located underneath. Here, the suitable choice of a dimension of the parallel keys 26 in the vertical direction or the height of which influences the vertical position or height at which the module 12 is fastened to the stand frame 1.

To further illustrate the module 12, this is in the Fig. 7-9 shown in further views. As already explained, this is an entry side module. Analogous to the representation of Fig. 4 are in the rear perspective view of Fig. 7 the four wedge elements that are used when attaching the module 12 to the stand frame 1 are each tightened to "14".
