- a radial-axial ring rolling mill of the type mentioned is shown in DE 10 2016 101 939 AI and is used for rolling seamless rings of a metal blank or a ring preform.
- the ring preform is reshaped from the original diameter to the desired final diameter by means of various rollers.
- the axial rolling device serves to deform the ring in the direction of its axis of rotation or an axis parallel thereto, i. for reshaping the
- the radial rolling device serves for forming the ring in a direction perpendicular thereto, ie in the direction of the radius of the ring to be formed.
- the terms “axial” and “radial” are used in the context of this description accordingly.
- the ring preform is placed on a substantially horizontal table and in the interior of the ring, a rolling mandrel is introduced, for example, from above.
- the rolling mandrel is mounted for vertical displacement on a mandrel bearing head arranged above the table and can be lowered until the lower end of the rolling mandrel engages in a lower mandrel bearing arranged below the table.
- the rolling mandrel In order to remove the rolled ring at the end of the rolling process, the rolling mandrel must be pulled out of the rolled ring, which is done by being pulled vertically upwards relative to the mandrel bearing head by means of a mandrel lifting device.
- a radial-axial ring rolling mill is used not only for a specific size of a ring to be rolled, but for ver ⁇ different ring sizes.
- rings are rolled, which can differ significantly in their axial height.
- relatively small rings with a small inner diameter and thus a corresponding small roll mandrel diameter and with a small axial ring height, there is a relatively high bending stress of the rolling mandrel, if the distance between the lower mandrel bearing and the upper mandrel bearing is too large.

- Machine frame can be attached.
- the adjusting movement is preferably carried out by means of at least one hydraulic piston-cylinder unit. To the 1st linear adjustment device and thus the
- linear to the path of the second linear Ver ⁇ steep device may preferably be continuously fixed or be adopted.
- the fixation by means of clamping, which can be done hydraulically and / or pneumatically.
- the upper end of the rolling mandrel is fixed in the mandrel bearing head by means of a mandrel bearing element.
- the mandrel bearing element can be removed upwards out of the mandrel bearing head.
- a new rolling mandrel can then be re-introduced from above into the mandrel bearing head together with a new mandrel bearing element and then fixed on the mandrel bearing head.
- the rolling mandrel can be rotated by a motor about its longitudinal axis, which is mounted for example on the mandrel bearing head and in particular on the mandrel bearing element. By the rotation of the rolling mandrel whose cooling can be improved.
- this engine can be switched off or switched passive.
- the guide carriage can be moved vertically as far upward that the rolling mandrel is completely moved out of the ring. In this way, the replacement of the ring or the insertion of a new ring preform is facilitated. Furthermore, it is provided that the guide carriage can be moved downwards so far that the effective rolling mandrel length, ie the distance between the lower mandrel bearing and the upper mandrel bearing head to the height of the to be wal Zenden Rings adapted and can be shortened in particular for rolling low rings.
- the rolling mandrel is held at its upper end to the mandrel bearing element, which is releasably fixable in the mandrel bearing head.
- the removable mandrel bearing element in the mandrel bearing head is preferably fixable by means of clamping.
- the motor by means of which the rolling mandrel is rotationally driven, preferably drives the rolling mandrel independently of the rolling moment of the ring to be rolled.
- the motor is designed so that it can drive the rolling mandrel in the non-productive times of the operation of the radial-axial ring rolling mill, for example in a workpiece change in order to cool the rolling mandrel better in these times, for example.
- the motor is preferably switched to passive.
- the mandrel bearing element attached to the upper end of the rolling mandrel is preferably held in the mandrel bearing head such that occurring tilting and / or rolling moments can be introduced into the mandrel bearing head.
- Table stored ring preform is the vertical 2.
- linear adjustment device activated from an upper position, whereby the guide carriage along with the mandrel bearing head and the mandrel along the path of the column is moved down and lowered until the mandrel with its lower end the ring Passes through preform and engages in the lower mandrel bearing.
- the first linear adjustment device 17 is activated, whereby the mandrel bearing head is moved with the rolling mandrel relative to the guide carriage in the direction of the main roll until the ring preform R is held between these two components in close fitting. Subsequently, the forming process is carried out in the usual way.
- Fig. L is a perspective view of a radial-axial ring rolling mill, wherein the rolling mandrel is arranged in a pulled-out from the ring preform position, and
- Fig. 2 the radial-axial ring rolling mill of Figure 1, wherein the rolling mandrel is lowered and passes through the ring preform.
