摘要： A rolling device (1), a method and a rolling train (35) for the cold rolling of rolled stock (3). The rolling device (1)-a rolling stand (5), multiple assembly sets for optionally assembling the rolling stand (5) with one of the assembly sets, and a working-roll drive. Each assembly set comprises two working rolls (7, 8), and for each working roll (7, 8) two working-roll chocks (9). A spindle head (11), can be connected to a working roll journal (16) of the working roll (7, 8). The working rolls (7, 8) of different assembly sets have different working-roll diameter ranges, which are determined by a respective minimum working-roll diameter and maximum working-roll diameter. The rolling stand (5) has mountings (19) for a respective working-roll chock (9) of an assembly set. The working-roll drive has two drive spindles (27), each for driving a working roll (7, 8) via the spindle head (11) assigned to the working roll (7, 8) by rotations about a longitudinal axis of the drive spindle (27).

At least one of the first power transmission path or the second power transmission path includes a first intermediate rotor fixed to an output shaft of the motor, a second intermediate rotor rotated by the first intermediate rotor and moving arcuately along an outer circumference of the first intermediate rotor, a driving shaft rotated by the second intermediate rotor and transmitting the driving force to the one driven shaft or the another driven shaft. The driving shaft is configured to move in a direction perpendicular to an axial center direction of the driving shaft in accordance with movement of the second intermediate rotor around the first intermediate rotor.

摘要： Control of third octave vibrations in a mill stand can be achieved using a high-speed piezoelectric assist coupled to a hydraulic gap cylinder to increase the damping of the roll stack. Vertical movements of the roll stack (e.g., the top work roll) can be determined through observation (e.g., measurement) of hydraulic fluid pressure of the hydraulic cylinder or entry tension of the metal strip. After determining vertical movements of the roll stack, a desired change in hydraulic pressure can be determined to overcome, reduce, or prevent third octave vibration. This desired change in hydraulic pressure can be effectuated at high speeds (e.g., at or above approximately 90 hertz) using the piezoelectric assist.

摘要： A roller leveler assembly has a first cassette having a first set of work rolls of a first diameter and work roll spacing and a second cassette having a second set of work rolls of a second diameter and work roll spacing. A drive mechanism selectively drives one of the first cassette of the first set of rolls and the second cassette of the second set of rolls. The drive mechanism has a first set of upper drive shafts and a second set of lower drive shafts and a drive shaft support assembly. The drive shaft support assembly has a first support shaft for supporting the first set of upper drive shafts and a second support shaft for supporting the second set of lower drive shafts. The first support shaft and second support shaft each has a first set of saddles and a second set of saddles for supporting the first set of upper drive shafts and the second set of lower drive shafts in first and second positions corresponding to the work roll center spacing of the first set of work rolls and the second set of work rolls, respectively.

摘要： A motor speed control device for a rolling mill, which includes a rolling roll that rolls a metal material, a roll rotation shaft directly connected to the rolling roll, a motor rotation shaft that transmits power to the roll rotation shaft, and a motor that drives the motor rotation shaft, includes: a non-contact type speed sensor arranged at a position close to the rolling roll with spacing to a circumferential surface of the roll rotation shaft to detect a roll rotation shaft angular speed of the roll rotation shaft; and a speed controller that controls a speed of the motor based on a comparison value between an actual value and a target angular speed of the rolling roll so that the actual value coincides with the target angular speed. The actual value is the roll rotation shaft angular speed to be fed back to the speed controller.

摘要： A drive shaft for transmitting motion to a roll of a tube rolling stand comprising a telescopic body, a slide and a support base. The telescopic body is fixed by one end with a cardan joint to the drive shaft of the gearbox, and on the other end has a fitting for attaching the roll. The slide is hinged to the support base and may rotate under the bias of a jack to either engage or release the telescopic body. A snap-action locking device, contained within the telescopic body, comprises a cylinder, on which two rocker arms are hinged, and a spring which spreads the rocker arms making the two teeth fit into two holes in the wall of the cylinder, when the drive shaft is at its maximum working length. The carriage has two pistons to work on the two rocker arms thus freeing the locking device and allowing the telescopic sliding of the cylinder in the cylinder and the downward rotation of the drive shaft.
