Document Type and Number:
Japanese Patent JP4749374
Kind Code:
B2
Abstract:
The roll stand for the rolling tube, comprises a roll (3) present on a roll shaft (2), which is detachably connected in an axial end over a coupling (4) with a drive shaft (5), and a roll changing device (6) exhibiting devices for lowering or lifting the roll from its working position into a roll changing position, drawing cars (9) for moving a coupling part (10) arranged in longitudinal direction of the roll shaft, coupling device, a coupling support for mounting the coupling in non-displaceable or fixed manner, and two roll racks fixedly arranged on base frame of the roll stand. Roll stand for the rolling tube, comprises a roll (3) present on a roll shaft (2), which is detachably connected in an axial end over a coupling (4) with a drive shaft (5), and a roll changing device (6) exhibiting devices for lowering or lifting the roll from its working position into a roll changing position, drawing cars (9) for moving a coupling part (10) arranged in longitudinal direction of the roll shaft, coupling device, a coupling support for mounting the coupling in non-displaceable or fixed manner, and two roll racks fixedly arranged on base frame of the roll stand. The coupling device is arranged in an axial end of the roll shaft with the coupling part arranged on the drawing cars. The coupling part is formed as a sheet with a slit- or U-shaped cavity and the coupling device is formed as a shaft with annular groove. The inner width of the groove in groove base is slightly smaller than the width of the slit- or the U-shaped cavity in the coupling part. The drawing cars exhibit a reception for one of chocks of the roll in order to move the roll in the axial displacement of the drawing cars, and a guidance forming a positive connection between the drawing cars and the chocks. The drawing car is movable relative to the roll stand in horizontal direction by means of a moving element (17). The guidance exhibits a contact surface extending vertically itself for the chocks.
