Abstract

A tapered roll stand for making seamless pipe has a stationary frame formed relative to a workpiece-travel direction with a pair of laterally and horizontally oppositely open windows. Respective cover doors carried on the frame are vertically shiftable between respective closed positions covering the respective windows and open positions offset therefrom and exposing the respective windows. A pair of tapered rolls are each shiftable horizontally through a respective one of the windows into a use position inside the frame, lying to a respective horizontal side of the direction, and rotatable about a respective axis forming an acute angle with the direction. A pair of Diescher disks are vertically engageable with a workpiece extending in the direction between the tapered rolls, and respective roll-positioning actuators carried on the doors are couplable with the tapered rolls in the use position for setting positions of the tapered rolls.

Description

technical field [0001] The invention relates to an oblique cone rolling mill (Kegelschraegwalzwerk) for the production of seamless tubes, which is implemented with driven two conical rolls ( Kegelwalze) and driven two guide disks or Diescherscheibe Diescher mills. Background technique [0002] A rolling mill of this type is known from EP 1 151 808 B1 in the form of a frame construction from modular units. In order to convert the rolling mill into a Diescher mill, associated with the two tapered rollers there are correspondingly arranged Diescher disks or guide disks on the Diescher disk slide, also called disk rollers (Scheibenwalze). The guide disc or Diescher disc closes the lateral nip between the upper and lower conical rolls as a quasi-revolving guide plate. The rolling stand frame consists of two gantry frames situated opposite each other at a distance, which are connected to the lower transverse frame and at the top by means of crossbars. The crossbars are movable ...
