Embodiment Construction

[0051] figure 1 The illustrated roll stand 1 has three rolls 2 , 3 , 4 which are formed and arranged in such a way that they form a pass K for rolling rod-shaped or tubular rolled parts. The first roller 2 of the three rollers is arranged on an input drive shaft 5 , which is designed as a plug-in shaft and inserted through an opening 16 into the carrier frame 10 from the outside. The second roller 3 of the three rollers is arranged on a sleeve 7 which is rotatably mounted on a first shaft 6 . The third roller 4 of the three rollers is arranged on a sleeve 9 rotatably mounted on a second shaft 8 .

[0052] The roller support according to the invention has a support frame 10 which accommodates an inner support 11 , wherein the inner support 11 is detachably connected to the support frame 10 and can be removed from the support frame 10 . Two radial bearings 12 and 13 of the input drive shaft 5 are arranged in the inner bracket. The first radial bearing 14 of the sleeve 7 on wh...

Abstract

The present invention relates to a roll stand having at least three rollers, each of which is configured to be of a hold shape for roll milling a bacillary or tubular roll milling member, the first roller is arranged on an input drive shaft, the second roller is arranged a sleeve rotatingly arranged on a first shaft, and a first auxiliary shaft or second input drive shaft rotatingly supported without drive outside the roll stand, the third roller is arranged on a sleeve rotatingly arranged on a second shaft, and a second auxiliary shaft or a third input drive shaft rotatingly supported without drive outside the roll stand, wherein the roll stand is provided with a stand frame for receiving an inner stand; the inner stand is detachably connected with the stand frame and may be fetched from the stand frame; at least one radial bearing of the input drive shaft is arranged in the inner stand; at least one radial bearing of the sleeve with the second roller, the first auxiliary shaft or the second input drive shaft is arranged in the inner stand; and at least one radial bearing of the sleeve with the third roller, the second auxiliary shaft or the third input drive shaft is arranged in the inner stand.

Description

technical field [0001] The invention relates to a roll stand with at least three rolls, which are constructed and arranged in such a way that these rolls form a pass (K) for rolling rod-shaped or tubular rolled parts, wherein the three The first of the rollers is disposed on an input drive shaft, the second of the three rollers is disposed on a sleeve rotatably supported on the first shaft, a non-following roller bracket rotatably supported The third roller of the three rollers is arranged on a sleeve rotatably supported on the second shaft, a rotatably supported not Either on a second layshaft driven externally from the roller bracket or on a third input drive shaft. The invention also relates to a method for changing rollers in such a roller stand. Background technique [0002] Roll stands with at least three rollers are usually used in rolling mill trains, which are constructed and arranged such that they form a pass for rolling rod-shaped or tubular rolled parts, said ...
