Abstract

The invention relates to a cross-rolling mill, having a plurality of roll shafts (1), each applying a radially directed rolling force to a workpiece, wherein orientation of a roll axis (w) of at least one of the roll shafts (1) adjustably changes about a first adjustment axis (S1) and a second adjustment axis (S2), wherein an intermediate member (9, 10) is arranged between a rotary baring (4, 5) and a control element (11, 12), and wherein the intermediate member (9, 10) includes a rolling force-transmitting rocker pin (14, 15) having a spherical surface (14a, 14b, 15a, 15b) that provides for pivotal movement in a plurality of directions.

First claim

The invention claimed is:

1. A cross-rolling mill, comprising:
a plurality of roll shafts ( 1 ), each having a rotary bearing and applying a radially directed rolling force to a workpiece, wherein an orientation of a roll axis (w) of at least one of the roll shafts ( 1 ) is adjustable about a first adjustment axis (S 1 ) and a second adjustment axis (S 2 ); and
an intermediate member ( 9 , 10 ) arranged between the rotary bearing ( 4 , 5 ) of at least one of the roll shafts and a control element ( 11 , 12 ), said at least one intermediate member ( 9 , 10 ) comprising a rolling force-transmitting rocker pin ( 14 , 15 ) having a spherical surface ( 14 a , 14 b , 15 a , 15 b ), said rocker pin supported via the spherical surface for pivotal movement of the rocker pin in a plurality of directions relative to the one of the roll shafts.

2. The cross-rolling mill according to claim 1 , further comprising at least one said rocker pin and at least one said rotary bearing arranged at respective opposite ends of each of said roll shafts.

3. The cross-rolling mill according to claim 1 , characterized in that each of the roll shafts ( 1 ) is received in a roll housing ( 6 ), said roll housing ( 6 ) movably supported about adjustment axes (S 1 , S 2 ), said rocker pin ( 14 , 15 ) supported against the roll housing ( 6 ) of the one of the roll shafts.

4. The cross-rolling mill according to claim 3 , further comprising a tension member ( 13 ), which applies a force to the roll housing ( 6 ) in a direction opposite a direction of the rolling force.

5. The cross-rolling mill according to claim 1 , characterized in that the rocker pin ( 14 , 15 ) engages at least at one end thereof, a bearing cap pivotable relative to the rocker pin.

6. The cross-rolling mill according to claim 1 , characterized in that the rocker pin ( 14 , 15 ), starting from a neutral position, is pivotable about a rotational point by an angle in each spatial direction.

7. The cross-rolling mill according to claim 1 , characterized in that at least two of the roll shafts ( 1 ) are adjustable about the first adjustment axis (S 1 ) and a second adjustment axis.

8. The cross-rolling mill according to claim 7 , wherein at least three of the roll shafts are adjustable about the first adjustment axis (S 1 ) and a second adjustment axis.

9. The cross-rolling mill according to claim 7 , wherein all of the roll shafts are adjustable about the first adjustment axis (S 1 ) and a second adjustment axis.

10. The cross-rolling mill according to claim 4 , wherein the tension member is a hydraulic tension member.
