Abstract

The invention relates to a rolling stock guiding device for a horizontal two-high rolling stand comprising a pair of rolls that can be inserted in the rolling stand and withdrawn therefrom while its bearing inserts (LS) rest on a carrier vehicle (TW). The rolling stand guiding elements (OFE, UFE) for the rest bar (WB) are disposed above and/or below the plane of movement of the strand of rolling stock passing through the rolling stand. Said guiding elements extend in parallel to the roll axis and can be vertically displaced and adjusted. The guiding elements (OFE; UFE) supporting the rest bar (WB) are linked with the free ends of a rest bar support pair (WT) which in turn is firmly linked with the bearing insert (LS) of the respective roll (WZ) and which projects therefrom in parallel to the direction of rolling.

Description

The present invention comprises a placed on the roll stand run and out can roll pair to rack and on carrying carriage by roll chocks, for the rolled material column above or below the plane of movement of the rolled material column through roll stand rack These guide elements are respectively pivotally attached to the rest bar, and both ends of the rest bar are coupled to a plate-like rest bar carrier disposed between the roll end face and the roll end face side surface of the roll chock. The present invention relates to a rolled material guide device for a horizontal two-stage roll mount.

This type of rolling material guide device is known from US Pat. The disadvantage of this device is that in order to change the distance between the guide elements carried by the rest bar, it is necessary to adapt to the strength of the rolling material row that passes each time, i.e. its rolling position. Is costly to remove and install and requires the use of skilled assembly personnel, since in most cases a spacing plate must be used between the end of the rest bar and the carrier .

The object of the present invention is to avoid this kind of cost and to automatically adapt the spacing between the guide elements to the strength of the row of rolling material passing through .

According to the present invention, according to the present invention, a guide groove extending in a straight line is formed on the side walls of the plate-like rest bar facing each other so as to receive and slideably guide the end of the rest bar. This is solved by having the rest bar carrier fixedly coupled to the roll chock of each roll .

The rolling material guide device configured as described above requires an auxiliary work for specially displacing or adjusting the position of the rest bar carrier in order to change the interval between the guide elements for the rolling material row. do not do. Because the rest bar carrier is fixedly coupled to the roll chock of each roll, the rest bar that is slidably guided in the guide groove of the rest bar carrier and carries the guide element performs a special position adjustment operation. This is because it automatically follows the rolling motion of the roll chock without any need.

Furthermore, according to the proposal of the present invention, the roll is attached to the roll mount using the roll chock, and the position between the outer surface of the plate- like rest bar carrier and the inner wall surface of the stand of the roll mount is determined. , the sliding plate Ru extending in the pressing direction can be arranged. In this case, plate-shaped rest bar carrier may be configured as a roll-side bearing cap for the ends of the roll chock which a end of the roll chock is adjacent to the end surface of the roll. Furthermore, a stand roll stand having one roll stand on each of the operation side and the drive side is provided, the roll stand on the operation side and the roll stand on the drive side can be connected to each other, and the roll stand on the operation side is rolled. In the rolling material guide device that can be moved toward and away from the drive side roll stand in a direction transverse to the direction, the operation side stand can be divided from the remaining stands so as to surround the roll chock of the roll from the side. In addition, it has an independent part that can be fixed to the remaining stand by a removable lateral fixing device, and the independent part is placed on the carrier carriage together with the roll and its roll chock and the rolling material guiding device, and remains. It may be configured to be able to run from the roll mount and to be able to run into the roll mount.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As can be seen from FIG. 1, the roll WZ is placed on a carrier cart TW that can run on a pair of rails with a roller RL, and two roll stands (the operation side roll stand WSB shown in FIG. 2 is guided using the roll chock LS in the stand window SF of the roll stand WSA on the driving side shown in FIG. The roll stand WSB on the operation side is composed of three parts, that is, an upper part WO, a lower part WU, and an intermediate part WM between them. The upper portion WO and the lower portion WU are combined with the drive side roll stand WSA in a manner not shown in FIG. 1 to form a unique roll base together with the drive side roll stand WSA. The intermediate portion WM, together with the roll WZ and its roll chock LS, can run on the carrier cart TW from a partial rack formed by the drive side roll stand WSA and the operation side roll stand portions WO and WU. The roll stand part WO, WM, WU on the operation side has a longitudinal groove LN (see also FIG. 2) on the outside, and the tension bar ZS pivotally attached to the lower roll stand part WAU is indicated by a double arrow DP. It can be turned inward into the longitudinal groove LN in the direction shown, or it can be turned outward from inside the longitudinal groove. The free end of the tension bar ZS is coupled to the tension motor ZM. The pulling motor ZM is supported on the upper surface of the roll stand portion WO at the inner rotation position of the pull rod ZS, and fixes the upper roll stand portion WO and the lower roll stand portion WU to the intermediate roll stand portion WM.

As can be seen from FIG. 2, plate-like rest bar carriers WT are disposed between both end faces of the roll WZ and the side faces of the roll chock LS attached to both end faces. The rest bar carrier WT protrudes beyond the roll and the side part defining the drive side roll stand WSA and the operation side roll stand WSB, and the end of the rest bar WB is vertically guided at the free end thereof. Receiving with FN (see also Figure 1). The rest bar carrier WT is fixedly coupled to the roll chock LS of each roll WZ. Also, the rest bar carrier WT, side surface portions of the roll chock LS forms a bearing cap for the end portion adjacent to the roll WZ an end of the roll chock LS. Between the outer surface of the protruding portion of the rest bar carrier WB and the inner surface of the roll stand, a sliding plate GL extending in the roll reduction direction is disposed.

  The upper guide element OFE and the lower guide element UFE for the rolled material are screwed to the rest bar WB via the intermediate carrier ZWT, and can be adjusted to the size of the rolled material using the position adjusting element SE.

  As can be seen from FIG. 1, the upper guide element OFE and the lower guide element UFE thus coupled to the upper and lower roll chock automatically follow the rolling movement of the roll WZ supported by these roll chock LS.

It is a partial cross section side view of a roll set which can enter into a roll stand and is provided with a rolling material guide device. It is sectional drawing by line AA of FIG.
