Abstract
A loading device for loading a roll may be connected without play to a roll shaft and may be supported by at least one bearing in a roll stand for rolling metal rods, bars, wires, or pipes from a roll or stock material, and a roll stand comprising such a loading device. The loading device may be configured to exert a force for calibrating a position of the roll in the roll stand, which may simulate a load on the bearing during rolling by applying the force to the roll or roll shaft.
Claims7
A loading device for a loading a roll, wherein the roll is connected without play to a roll shaft, wherein the roll shaft is supported by means of at least one bearing in a roll stand for rolling metal rods, bars, wires or pipes from a roll material,
- wherein said loading device is configured to exert a radial force for calibrating a radial position of the roll in the roll stand, wherein the radial force simulates a load during rolling on the bearing and on parts of the roll stand involved in supporting the roll,
- wherein the loading device is configured to apply the radial force to the roll shaft or to apply the radial force to the roll, and
- wherein the loading device is configured to apply the radial force with one of a hydraulic cylinder, at least one push rod driven by a threaded spindle, or via the movement of wedges.
A roll stand or a roll block in a rolling mill for rolling metal rods, bars, wires or pipes from a roll material, the roll stand comprising:
- at least one roll, wherein the roll is connected without play to a roll shaft, wherein the roll shaft is supported by at least one bearing in the roll stand, wherein the roll forms a calibre, and
- a loading device configured to exert a radial force for calibrating a radial position of the roll in the roll stand, wherein the radial force simulates a load on the bearing of the roll shaft during rolling by applying the radial force to the roll shaft or by applying the radial force to the roll, and
- wherein the loading device is configured to apply the radial force with one of a hydraulic cylinder, at least one push rod driven by a threaded spindle, or via the movement of wedges.
