Definitions
- the invention relates to interchangeable bearing insert pairs for the vertical rolling of universal stands for the optional rolling of Beams, in particular H-beams of different web heights, where the universal frameworks stationary guide surfaces for the sliding surfaces of the bearing insert pairs exhibit. when rolling such beams, it is necessary to change the height of the horizontal longitudinal center plane of the vertical rollers opposite the upper edge of the the carrier to and from the roller table to adapt to the respective To change the beam height.
- This height adjustment has been either achieved by applying inserts on the guide surface of the universal scaffold or the sliding surfaces of the bearing chocks of the vertical rollers were placed (JP 591 742 05) or with one of the bearing chocks of the vertical rollers detecting sliding wedge arrangement, with the help of the bearing chocks could be moved up or down (JP 526 140 6).
- This type of adjusting device is technically complex and requires in operation a considerable amount of space for the exact adjustment of the desired change in the height of the vertical rollers and their definition against the stresses that arise during the rolling operation or against the Rolled stock itself caused impacts when it entered and exited the roll gap.
- the invention has for its object to reduce this technical effort and avoid extra work.
- This object is achieved in that the two vertical distances between the levels the upper and lower sliding surfaces from the horizontal longitudinal center plane of the respective bearing insert pairs according to the web height of each dimensions of the beam to be rolled are different.
- the invention is based on the embodiment shown in the drawing explained in more detail.
- the drawing shows the view of a partially cut Section of a universal roll stand, from the side across to Seen rolling direction. From the drawing it can be seen that in the The bearing chocks 1 of the scaffold frame of the universal rolling stand and 2 of the upper and lower horizontal rolls 1a, 2a, vertically are led.
- the carriers not shown, are over the Roller table 3 in the roll stand between the two horizontal rolls 1a, 1b guided and acted on the side by the vertical rollers.
- These vertical rollers each belonging to a pair of vertical rollers, are to the left of the vertical one in the embodiment Center line of the drawing with 4 and to the right of the center line with 5 designated.
- the vertical roller 4 is supported in a bearing chock 6 and the vertical roller designated 5 are mounted in a bearing chock 7.
- the vertical distance of the longitudinal center next to LM 5 of the (right) Vertical roller 5 from the roller table top edge RK is through the Shelf 8 determined on the guide surfaces 7a and 7b; he can by exchanging these insert strips 8 for those with others Strengths or other side dishes can be changed.
- the vertical distances dl and d2 of the horizontal longitudinal median plane LM 4, here the vertical roller 4 from the planes of the guide surfaces 6a and 6b are of different sizes here and lead to one asymmetrical design of the vertical cross section of the housing of the Bearing chock 6 while reducing the distance of the longitudinal center plane LM 4 from the top of the roller table RK.
