Description

[0001]
[Industrial technical field]
The present invention relates to an apparatus that facilitates restraining of roll chocks and recombination of brush rolls in an apparatus for brushing or polishing (hereinafter simply referred to as brushing) the surface of a metal slip in a threaded plate with a rotating brush roll. is there.
[0002]
[Prior art]
Conventionally, as a device for restraining a roll chock of a brush roll, for example, an “automatic restraining device for the front and rear direction of the roll chock of a brush roll” described in JP-A-6-126612 is known. This device is provided with a lever clamp that is directed to the roll chock by means of a spring biased to the pressing body corresponding to the inner stand, and by inserting a protruding stopper provided on the lever clamp into a recessed portion provided on the roll chock, It is restrained to the pressing body by a spring biasing force.
[0003]
However, in this apparatus, since the force restrained by the roll chock is due to the spring biasing force, the rotating brush roll vibrates due to insufficient restraining force, and a chatter mark (striped pattern) is generated on the strip. Moreover, since the rail for changing a brush roll is provided in the lower surface (downward) of a press body, the whole apparatus becomes vertical and may not be installed in the existing stand. Further, when the roll is replaced, it is necessary to lift the extracted roll upward. However, since the rail is positioned above the roll in this apparatus, it cannot be lifted in the state of being extracted.
[0004]
[Problems to be solved by the invention]
The present invention prevents the occurrence of chatter marks by more reliably restraining the roll chock in an apparatus that brushes or polishes the surface of a metal slip in a plate with a rotating brush roll, and makes the entire apparatus compact. It is an object of the present invention to configure and easily perform brush roll rearrangement.
[0005]
[Means for Solving the Problems]
The roll chock restraint device of the present invention that solves the above problems is a roll stand that is configured to press-contact a rotating brush roll to the surface of a strip that passes through a pass line, and is provided with lifting rails on both the front and rear sides of the outer stand, An elevating guide fitted to the elevating rail is provided on the inner stand, a pair of traverse rails along the roll axis direction of the brush roll is provided on the inner stand, and a roll chock is mounted on the traverse rail via a wheel. A linear actuator that is supported and driven in the front-rear direction is provided on the inner stand on one of the front and rear sides of the inner stand , a clamp rod is provided on the rod of the linear actuator, and a concave portion into which the clamp rod is fitted. A portion is provided in the roll chock.

DETAILED DESCRIPTION OF THE INVENTION
1 and 2 are side views of the entire roll chock restraint device according to the present invention, FIG. 3 is a partially enlarged view of FIG. 1, and FIG. 4 is a plan sectional view taken along line AA of FIG. 2 continues on the right side of FIG. 1, and two roll stands 1a and 1b for the upper surface brushing and the lower surface brushing of the strip are installed on the pass line L of the metal strip S. Since the stand has a vertically inverted structure and basically has the same structure, only the roll stand 1a for the upper surface in FIG. 1 will be described in the following description. The roll chock restraint device according to the present invention is provided on both the left and right sides of the brush roll, but basically has the same structure on the left and right, and therefore only the front side of the drawing will be described in the following description.
[0007]
In FIG. 1, the outer stand 2 is provided with a reduction device 3, and the reduction device 3 is provided with an inner stand 4. As shown in the plan view of FIG. 4, lateral rails 6, 6 extending in the axial direction of the brush roll are provided on both the front and rear sides of the inner stand 4. As shown in the side view of FIG. 3, a roll chock 7 is mounted and supported via wheels 8 and 8, and the roll chock 7 can move on the rails 6 and 6 for lateral running.
[0008]
As shown in FIGS. 3 and 4, elevating rails 10 and 10 are provided on both the front and rear inner sides of the outer stand 2, and elevating guides 9 provided on the inner stand 4 are provided on the elevating rails 10 and 10. 9 are fitted. A linear actuator 11 that drives in the direction of the pass line is provided on the front and rear side (rear side) of the inner stand 4, and a clamp rod 12 is provided on the rod of the linear actuator 11. The clamp rod 12 can be fitted into the recessed portion 13 provided in the roll chock 7 by driving the direct acting actuator 11, and the roll chock 7 can be restrained to the inner stand 4. Note that the transverse rail 6 and the inner stand 4 are provided with idiot holes (the portion of the clamp rod 12 in the figure) through which the clamp rod 12 passes.
[0009]
In FIG. 1 and FIG. 2, reference numeral 14 denotes a spray header for supplying a cooling liquid or cleaning liquid to the metal strip S and brush roll 5 during brushing, and reference numeral 15 denotes a backup roll for supporting the metal strip S.
[0010]
Next, the operation status of this apparatus will be described. When the roll chock 7 is restrained by the present apparatus, the clamp rod 12 is fitted into the recessed portion 13 when the linear actuator 11 is extended in FIGS. By fitting the clamp rod 12 into the recessed recess 13, the gaps 16 and 17 shown in FIGS. 3 and 4 are eliminated, and the roll chock 7 is restrained from moving back and forth, left and right, and up and down. The gaps 16 and 17 are provided in order to facilitate the attachment and detachment of the brush roll 5.
[0011]
When the metal strip S is polished, the brush roll 5 is rotated and pressed against the metal strip S by the reduction device 3, but the clamp rod 12 is firmly fitted into the recessed portion 13 as shown in FIGS. Therefore, the movement of the roll chock 7 in the front-rear direction, the right-left direction, and the up-down direction is strongly restrained by the direct acting actuator 15. For this reason, it is possible to prevent the vibration generated with the rotation of the brush roll 5 and to prevent chatter marks on the metal strip S due to the vibration.
[0012]
When the brush roll 5 is taken out from the roll stand 1a, the reduction of the brush roll 5 by the reduction device 3 is released, and when the linear actuator 11 is contracted and the clamp rod 12 is extracted from the recessed portion 13, the roll chock 7 is The restraint with the inner stand 4 is released, and the brush roll 5 can run on the traverse rail 6 together with the roll chock 7. Therefore, the brush roll 5 is pulled out and placed on a roll receiving carriage (not shown) and conveyed to a predetermined position.
[0013]
When a new brush roll is mounted on the roll stand 1a, the brush roll mounted on the roll receiving carriage is positioned at the end of the roll stand 1a, and the wheels 8 and 8 provided on the roll chock 7 are placed on the traversing rails 6 and 6, respectively. In this state, the brush roll can be mounted by being pushed into the roll stand 1a. In the above description, an apparatus for polishing the upper and lower surfaces of the strip is shown, but an apparatus for polishing one of the upper and lower surfaces may be used. Furthermore, it may replace with the backup roll 15 shown in FIG. 1, and you may provide the brush roll 5 which has the roll restraint apparatus of this invention.
[0014]
【The invention's effect】
According to the apparatus of the present invention, (1) chatter marks on the metal strip due to vibrations of the brush roll can be prevented by restraining the movement of the roll chock in the front / rear, left / right and up / down directions. (2) Since both front and rear sides of the roll chock are mounted and supported on the traverse rail provided on the inner stand, the entire apparatus is compact and the brush roll can be easily replaced.
