Definitions

the invention relates to a reversible profile roll stand with multi-caliber rolls, the bearing pieces of which are adjustable in windows of the stands of the roll stand, for arrangement together with other, similar roll stands, side by side in rows transverse to the rolling direction, the rolls on both end faces with the drive devices or drive transmission elements arranged between the rolls of adjacent roll stands can be connected, and for each of the rolls of the roll pairs on both sides of the roll gap, special adjustable and definable rolling stock guide guides assigned to the profile calibers are each arranged together on supports which can be connected to the roll stand.
Reversible duo-profile rolling stands of this design and arrangement are used for rolling a wide variety of profiles in such a way that the rolling stock in successive passes is first reversibly fed to the calibres of one rolling stand and then to the calibres of the adjacent rolling stand in the row.
the rolling stands in a row are driven by one with the rollers one, the beginning of a row-forming roll stand coupled drive device, and the transmission of the drive force takes place via the rolls of this stand to the rolls of the next stand of the row by the drive transmission elements coupling the two stands together.
the rolling stock guides assigned to the individual rolls of the stands are arranged on rolling beams which are firmly connected to the spars of the roll stands; They must be set to the caliber of the respective roll assigned to them before the rolling process begins and generally remain in this setting position until the roll stands are to be converted to rolling other profiles.
This change is made by replacing the roll sets of all roll stands with others.
the rolling stock guide rails must be brought out of their set position, either by completely removing them, or by pivoting or shifting them on the roller beam in order to bring them out of the removal path of the rollers.
the complete expansion of the rolling stock guideways is particularly unavoidable if other types of guiding guideways are required for the calibres of the new rolls.
roller sets also requires a relatively large amount of time and experience with this configuration and arrangement of duo-profile roll stands, because the roller sets with their bearing pieces cannot be easily moved out of or into the stands of the stands through their windows .
the stands in a row are relatively close together and hinder the expansion of the roller sets accordingly.
the bearing pieces after loosening the connections to the drive device and the drive transmission elements, the bearing pieces must first be pulled off the ends of the rollers and the rollers, bent obliquely upwards, must be pulled out of the respective window over the adjacent stand.
the invention has for its object to improve the reversible duo-profile rolling stands intended for the generic arrangement in such a way that the positioning and adjustment work on the rolling stock guide guides and the additional fittings is simplified, the downtimes caused by them considerably reduced and the replacement of the Roller sets are also simplified and the time required for this can be reduced.
This object is achieved in that the roller stands have known, hinged to their spars, which can be pushed out or swung out for the expansion of the rollers, and the bearing pieces of the roller pairs can be inserted into a support frame which is inserted between the spars of the stands. and can be lifted out of them, and into which the carriers of the rolling stock guide guides can be inserted.
the support frame can consist of a parallel-sided, U-shaped plate pair connected by spacers, into whose, in the installation position open upward U-recess, the bearing pieces of the rollers, guided in the U-flange area, can be inserted, wherein the web areas of the U-recess form support surfaces for the underside of the bearing pieces of the lower rollers, and which has opposing slot recesses for inserting and displacing the carriers of the rolling stock guide rails.
the U-recess can have, in the opening area, mutually opposite, projecting into the opening, graspable from the upper corner edges of the bearing pieces of the upper roller, which make it possible to lift the supporting frame formed by the pair of plates with the roller when lifting the upper roller.
the roll stand 1 is formed from the stands 2 and 3 with the spars 2a, 3a and the connecting caps 4 and 5.
the connecting caps 4 and 5 are rigidly connected to one another by a crossbar 6.
the adjusting spindles 7 are threaded in spindle nuts 8; they are driven together via adjusting gear 8a arranged on the connecting caps 5 and which are coupled to one another via a connecting shaft 9.
the upper and lower rollers of the duo roller set here have six caliber channels, which together (see FIG. 1) form the roller calibers indicated there.
the bearing pieces 14 of the upper roller 10 and the bearing pieces 15 of the lower roller 11 are (FIG. 2) in the fen formed by the spars 2a, 3a star 2c or 3c led.
the bearing pieces 14 hang with hook attachments 14a on a lifting traverse 16, which has a crane eye 16a.
the lifting crossbar 16 in turn hangs on lifting cylinders 37 which are connected to the crossbar 6 and is acted upon by the adjusting spindle 7.
the lower roller 11 is also guided with its bearing pieces 15 in the windows 2c and 3c of the stands 2 and 3.
both parallel-surface plates 17 and 18, in the installed state have mutually opposite slot recesses 21, in which the rolling beams 22, 23 and 24, 25 arranged upstream of the entry and exit sides of the roll nips and the respective rolls can be moved and fixed.
six rolling guide guides 26, 27, 28, and 29, respectively are arranged to be adjustable and fixed.
outwardly directed cantilever projections 30 are attached in the web area of the U-recesses 20 of the parallel-surface plates 17, 18. These cantilever projections 30, with their surfaces pointing downward, can be placed on the lower boundary of the windows 2c, 3c of the roller stands 2, 3 (cf. FIG. 2).
the one from the upper roller 10, the lower roller 11, the bearing pieces 14 and 15, the roller beams 22, 23, 24, 25 and the one mounted on them 3, 4 and 5, the parallel set of plates 17, 18 hold and carry in connection with the lifting cross member 16 and the positionally positioned rolling stock line guide sets 26, 27, 28, 29. It can be lifted upwards out of the roll stand 1 from the rolling position shown in FIGS.
the upper bearing piece 14 which for this purpose has lateral cantilever projections 33, is held by projections 17a or 18a, which project into the opening opposite one another in the opening area of the U-recess 20, after it has been removed from bearing piece 15 was moved away.
the cantilever lugs 33 in the place of which, for example, the upper corner edges of the bearing pieces can also occur, underlie the lugs 17a and 18a.
the roll set After the roll set has been lifted out, it can be replaced by a roll set prepared outside of the roll stand 1 and made ready for rolling, and the rolling process can be continued immediately after the connection caps 4, 5 have been reinstalled.
the interruption in time is limited to the lifting and reinserting of the roll sets that are completely prepared outside the roll stands.
