Detailed Description

For ease of illustration and ease of understanding, several basic directional and positional concepts are first described and defined. The power side or end of the rolling mill or the roller refers to the side of the roller connected with the power shaft at the shaft end, and the opposite side or end is an operation side or end; the up and down directions are directed to a state where the roll is horizontally placed, and the following description will be given by taking this state as an example only. The rolling mill can be placed in a vertical mode of the roller to perform rolling.

As shown in fig. 1 to 6, an online compensation device for a roller includes a lower chock 10, a base 20 is disposed below the lower chock 10, the lower chock 10 and the base 20 form a limit fit in an axial direction of the roller and a limit fit in a traveling direction of a material, and an adjusting mechanism 30 for adjusting an upper position and a lower position of the lower chock 10 is disposed between the lower chock 10 and the base 20. The lower chock 10 and the base 20 cannot move relatively in the axial direction of the roll and the advancing direction of the material, but can move relatively in the vertical direction, the adjusting mechanism 30 is arranged between the lower chock 10 and the base 20 to adjust the gap between the lower chock 10 and the base 20, and the base 20 is fixed, so that the movement of the lower chock 10 in the vertical direction, namely the height of the roll core of the lower roll is adjusted to compensate the abrasion of the roll surface.

Preferably, the feeding side and the discharging side of the lower bearing seat 10 are provided with upright rods extending upwards, and the upper bearing seat 40 is arranged in the area between the two upright rods on the lower bearing seat 10 at one end.

In a preferred embodiment of the present invention, the adjusting mechanism 30 includes a bottom plate 31, the bottom plate 31 and the rail 21 provided on the base 20 form a sliding fit along the axial direction of the roll, a wedge 32 is provided on the upper surface of the bottom plate 31, and the upper inclined surface of the wedge 32 and the lower inclined surface provided at the lower end of the lower chock 10 are attached to each other to form a sliding fit and drive the lower chock 10 to move up and down. The adjusting mechanism 30 is inserted from the power end or the operation end of the base 20 and the lower bearing seat 10, the upper inclined surface of the wedge 32 and the lower inclined surface arranged at the lower end of the lower bearing seat 10 move relatively, namely the wedge 32 moves to drive the lower bearing seat 10 to move up and down, and the wedge 32 supports the lower bearing seat 10 to realize the adjustment of the upper and lower positions of the lower bearing seat 10.

Preferably, the lower end of the lower bearing seat 10 is provided with a guide groove 11, the notch of the guide groove 11 faces downwards, the groove length of the guide groove 11 is parallel to the axial direction of the roller, the groove bottom of the guide groove 11 forms a lower inclined plane, the wedge 32 is arranged in the guide groove 11, and the groove wall of the guide groove 11 and the wedge 32 form guiding and limiting matching. The guide groove 11 is directly arranged on the lower bearing seat 10, and the lower bearing seat 10 and the wedge block 32 slide stably and reliably due to the guiding and limiting effects of the groove wall. Fig. 5 is a schematic diagram before adjustment, at this time, the gap 1 between the lower chock 10 and the base 20 is small, the distance between the upper and lower rolls is large, and the rolling requirement cannot be met, the wedge 32 is moved rightward, as shown in fig. 6, the gap between the lower chock 10 and the base 20 is changed to 2, 2 > 1, and the distance between the upper and lower rolls is reduced to meet the rolling requirement.

The wedge 32 is provided at each of four corners of the bottom plate 31 in number of 1, the guide groove 11 is provided in number of 4, and a missing portion 311 is provided in the middle of the bottom plate 31. Wedge 32 arranges under the lower bearing frame 10, rationally provides the support position, and 4 wedge 32 disjunctor shaping, when convenient processing, still provide operating space for roll change operation.

The end of the bottom plate 31 is provided with a T-shaped head 33 clamped by a driving mechanism, the moving direction of the driving mechanism is arranged in parallel with the axial direction of the roller, and the end of the bottom plate 31 adjacent to the T-shaped head 33 is provided with a stop block 34 in a downward protruding mode. The driving mechanism controls the stroke of the T-shaped head 33 and plays roles of supporting, supporting and limiting the bottom plate 31.

Correspondingly, the height of the roller core of the upper roller is also adjusted adaptively, the position of the center line of the distance between the upper roller and the lower roller after compensation is ensured to be consistent with the position of the center line of the distance between the upper roller and the lower roller before compensation, and a servo oil cylinder for pressing the upper bearing block 40 downwards is arranged on the upper cross beam.
