Method for modifying the distance between the rollers of a leveling machine, leveling machine, and apparatus for implementing said method |
摘要 |
A machine for leveling a strip of material includes a fixed supporting frame; an upper leveling device and a lower leveling device, each leveling device forming a cassette with a plurality of separated rollers, rotatably mounted on a frame of a device for rotating the rollers connected to at least some of the rollers by an extender, each extender having one end provided with a removable coupling member with one end for rotating the roller, and a device for locking each removable coupling member by clamping. The clamping locking device includes a device configure for translating the removable coupling members in the direction of travel of the material, and in the opposite direction. |

1. A leveling machine for leveling a strip of material, comprising:
a fixed supporting frame including four posts disposed on each side of a longitudinal axis of travel of the material, a fixed base firmly holding said posts in a lower part thereof, and transverse beams firmly holding said posts in an upper part thereof, with an assembly of said posts, said base, and said beams forming a closed frame; a lower leveling device resting on said fixed base and an upper leveling device resting on a pressure frame disposed for vertical movement between said four posts, each said leveling device forming a cassette with a plurality of separated rollers, rotatably mounted on a frame around axes perpendicular to the longitudinal axis of travel of the material; a rotating device for rotating said rollers connected to at least some of said rollers by way of an extender, each extender having a first end rotated and a second end fitted with a removable coupling member with one end driving a roller, said extenders being disposed on two levels, including a lower level coupling with said rollers of said lower leveling device and an upper level coupling with said rollers of said upper leveling device; a locking device for locking each removable coupling member by clamping at a predetermined height during device changing phases; said locking device including moving devices configured to translate said removable coupling members in the direction of travel of the material and in the opposite direction; and a dismantling device for dismantling each of said upper and lower leveling devices by moving, perpendicular to the axis of travel, between a working position inside said frame and a withdrawn position offset laterally on one side of the frame opposite a drive side thereof. |
