Definitions

• the invention relates to a rolling stock guiding device for horizontal duo-roll stands with a pair of rolls which, with its bearing chocks resting on a carrier, can be moved into and out of the rolling stand, above and below the plane of movement of the rolling stock passing through the rolling stand being vertically adjustable, parallel to the Wear roll bar guide elements that run along the roll axes for the rolled strand.
• the rolling beams of this type which carry the guide elements are arranged on the uprights of the rolling stand; they are generally provided with displacement devices for adjusting the guide elements to the dimensions of the rolling stock passing through the rolling stand.
• the arrangements of the shifting devices on the stands of the roll stand require not only a special design and construction effort for the stand, but also for the shifting devices themselves and their drive, as well as motion controls.
• the invention has for its object to provide a rolling stock guiding device in which this effort is avoided.
• This object is achieved in that the rolling beams carrying the guide device can be connected to the free ends of a pair of rolling beams which are fixedly connected to the bearing chocks of the respective roll and project from them parallel to the rolling direction.
• the two supports of this pair of roller beams can each be arranged between the end face of the roller and the side surface of the bearing insert facing it and, in the form of a plate, can be designed as a roller-side bearing cover of the bearing of the bearing insert adjacent to the end face of the roller.
• these rolling stock guiding devices can also be arranged in a separable stand rolling stand with two stands that can be coupled to one another, from which the operator-side stand can be moved transversely to the rolling direction on the drive side, or can also be arranged in a stand rolling stand, the operator-side stand of which is one the position chocks of the rollers laterally enclosing, separable from the rest of the stand, which can be clamped with this by releasable lateral tensioning devices, which together with the rollers, their bearing chocks and the rolling stock guiding devices, lying on the carrier carriage, can be moved out of the remaining rolling stand and into it is trained.
• This design of the rolling stock guiding devices does not require any special additional shifting and adjusting devices, because the supports, which are firmly connected to the bearing chocks of the rolls and the associated rolling beams, which support the guiding devices, automatically follow the positioning movements of the bearing chocks without the need for additional adjusting devices.
• FIG. 1 shows the partially cut Side view of a roller set retracted in a roll stand with the guide devices and FIG. 2 shows a section along the line AA through FIG. 1.
• the rollers WZ lie on a carrier carriage TW that can be moved with rollers on a pair of rails SP, with their bearing chocks in the stand windows of two roller stands, the operator-side roller stand WSB shown here and the drive-side roller stand WSA shown in FIG. 2 guided.
• the operator-side roll stand WSB consists of three sections, namely an upper section WA, a lower section WU and a section WM located between them.
• the upper section WO and the lower section WU are, in a manner not shown here, connected to the drive-side roll stand WSA and form the actual roll stand with it.
• the middle section WM together with the rolls WZ and their bearing chocks LS on the carrier car TW, can be moved out of the partial stand formed by the drive-side roll stand WSA and the two operator-side roll stand sections WO and WU.
• the operator-side roller stand sections WO, WM and WU have longitudinal grooves LN on the outside (cf. also FIG. 2) into which tie rods ZS articulated in the lower roller stand section WAU can be pivoted in and out in the direction of the double arrow DP.
• pull rods ZS are connected at their free ends to pull motors ZM, which are supported in the pivoted-in position of the pull rods ZS against the upper side of the roll stand section WO and allow the upper roll stand section WO and the lower roll stand section WU to be braced with the middle roll stand section WM.
• plate-shaped roller beam supports WT are arranged between the two end faces of the roller WZ and the associated sides of the bearing chocks LS, which here are located above the roller and the lateral boundaries of the drive-side roller stand WSA and the operator side Roll stand WSB also protrude and take up the ends of the roll bars WB at their free ends in vertical guide grooves FN (cf. also FIG. 1).
• the section of the roll beam carrier WT facing the side of the bearing chocks LS forms the bearing cover of the bearing, not shown, adjacent to the roll WZ in the bearing chock LS.
• sliding strips GL are arranged in the direction of adjustment of the rollers.
• the upper guide elements OFE and the lower guide elements UFE for the rolling stock are screw-connected to the rolling beams WB via intermediate supports ZWT and can be adjusted to the rolling stock dimensions using adjusting elements SE.
• the upper and lower guide elements OFE and UFE which are connected to the upper and lower bearing chocks in this way, automatically follow the positioning movements of the rollers WZ mounted in these bearing chocks LS.
