Abstract

A universal rolling mill stand with horizontal and vertical rolls, adjustably supported in two parallel roll posts is disclosed. The universal rolling mill stand enables a simple construction and operational process if the horizontal rolls are received, without the help of installation pieces in bearings disposed in the roll posts 3, operator side roll post with the bearings face away from the drive elements and can be moved away in rolling axis direction of the horizontal rolls, from the other roll post. Vertical rolls, supported in adapters, are slid into guide frames solidly connected with the roll posts.

Claims

1. A universal rolling mill stand, comprising:

horizontal and vertical rolls;

spaced first, drive side roll stand post and second operator'"'"'s side roll stand post extending parallel to each other for supporting said horizontal and vertical rolls, the second, operator'"'"'s side roll stand post being axially movable relative to the first, drive side roll stand post;

bearing means located in said first and second roll stand posts for supporting the horizontal rolls therein;

a horizontal guide frame located in each of said first and second roll stand posts for supporting a respective vertical roll therein;

tie rods for connecting the horizontal guide frame to a respective one of said first and second roll stands;

an adapter for receiving the respective vertical roll and arranged in said horizontal guide frame, said adapter having spaced separate horizontally extending top and bottom plates and a vertical support axle extending between said horizontal separate top and bottom plates for supporting the respective vertical roll, the guide frame comprising a recess for the adapter and accessible from a space between said first and second roll stand posts; and

a U-shaped abutment part located in said recess for positioning said adapter in said recess, wherein said guide frames are configured in two parts, an adapter support part and a crosshead connected to said adapter support part and located on a side of a respective roll stand post remote from the space between said roll stand posts,

wherein the universal rolling mill stand further comprises a vertical roll screw-down or adjustment system disposed in each crosshead, said U-shaped abutment part being disposed between said adapter and said roll screw-down or adjustment system.

2. The universal rolling mill stand of claim 1, wherein the vertical roll screw-down or adjustment system, comprises:

a wedge adjustment; and

shimstock loaded against the adapter by said wedge adjustment.

3. The universal rolling mill stand of claim 1, wherein said horizontal rolls are single part horizontal rolls.

4. The universal rolling mill stand of claim 1, wherein said horizontal rolls are multipart horizontal rolls braced by tie rods (15) to form a single unit.

5. The universal rolling mill stand of claim 4, further comprising a worm drive, wherein the horizontal rolls are disposed in eccentrics displaceable or adjustable by the worm drive.

6. The universal rolling mill stand of claim 5,

wherein the adapters are provided each with a mounting at an internal side thereof facing a rolling gap and located opposite of the mounting of another adapter;

and

wherein the rolling mill stand further comprises opposite rolling material side guides located at inlet and outlet sides and acting upon respective mountings.
