Abstract

Disclosed is a device for bending the rolls in a roll stand comprising several rolls. Said device is provided with bending blocks which are fastened between the built-in roll parts and the stand windows at the delivery end and the discharge end, the top and bottom bending blocks being connected by means of piston cylinders and/or a vertical positioning mechanism, preferably a spindle-type lifting gear unit. A bending force can be introduced into the bending blocks (5, 5a) which are connected on the same side via a piston cylinder (7) while the opposite bending blocks (5', 5a') can be positioned and locked via the spindle-type lifting gear unit (10).

Claims (4)

1. Device for bending the rolls in a rolling stand comprising several rolls with the use of bending blocks, which are mounted at the run-in end and the runout end between the roll chocks and the housing windows and can be acted upon by control elements, characterized by the fact that a piston-cylinder (7) is assigned to the bending blocks (5, 5a) of one of the mill housings (6), and a vertical positioning mechanism (10) is assigned to the bending blocks (5', 5a') of the opposite mill housing (6').
2. Device in accordance with Claim 1, characterized by the fact that a roll change position can be vertically adjusted by the vertical positioning mechanism (10).
3. Device in accordance with Claim 1 or Claim 2, characterized by the fact that the piston-cylinder (7) comprises a piston (8) mounted in one of the bending blocks (5) and a connecting rod (9) to the other bending block (5a).
4. Device in accordance with any of Claims 1 to 3, characterized by the fact that the vertical positioning mechanism (10) is designed as a spindle-type lifting gear unit, as wedges with restricted guidance, as a cylinder with clamping head and position sensor, as an eccentric shaft, or as another type of mechanism for vertical positioning.
