Abstract

PROBLEM TO BE SOLVED: To automatically polish a roll at constant speed under constant pressure without relying on manpower by reciprocating a polishing bar by normal rotation-reverse rotation of a driving motor through a rack-and-pinion by pressing it down to the roll by pressure of a spring. SOLUTION: A polishing bar 4 is guided by a slider 7, and is vertically pushed to rolls 12 and 13, and pressure is imparted by a spring 5. Pressure of the polishing bar 4 can be adjusted by an adjusting handle 6 by using a slider 8 as a guide. When the polishing bar 4 is reciprocated to surfaces of the rolls 12 and 13, it is performed by guiding normal rotation-reverse rotation of a driving motor 11 by a slider 9 through a rack-and-pinion 10. The normal rotation-reverse rotation of the driving motor 11 are switched to/from each other by a limit switch. Therefore, the roll can be automatically polished at constant speed under constant pressure without relying on manpower.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to polishing of a rolling mill.

[0002]

2. Description of the Related Art In conventional roll polishing, polishing is performed by reciprocating a polishing rod 4 by applying pressure manually as shown in FIG.

[0003]

As shown in FIG. 4, in the conventional manual roll polishing, a person holds the polishing rod 4 by hand for a long time and applies pressure to the rolls 12 and 13 to reciprocate left and right. Therefore, there has been a problem that there is variation in the surface after polishing due to human fatigue and human polishing. In addition, since the rolls 12 and 13 are rotated from the vertical insertion direction in the work place, there is a risk that the rolls 12 and 13 may be accidentally caught in the rolls 12 and 13.

An object of the present invention is to automatically perform roll polishing at a constant pressure and a constant speed without relying on manual labor.

[0005]

In order to achieve the above object, in an automatic roll polishing machine according to the present invention, a polishing rod is pressed against rolls 12 and 13 by the pressure of a spring 5 and driven by a rack and pinion 10 via a rack and pinion 10. The motor 11 is reciprocated by forward and reverse rotations.

In order to adjust the pressure of the spring 5, it is effective to attach an adjusting handle 6.

In order to adjust the reciprocating speed, it is effective to use a speed control motor for the drive motor 11.

It is preferable to attach limit switches 1 and 2 at both ends to adjust the reciprocating stroke.

When the apparatus is attached to and detached from the roll mill 1, it is preferable that a positioning mechanism is provided.

If the polishing time is set by a timer, it can be stopped automatically.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG.
Is guided vertically by the slider 7 and pressed perpendicularly to the rolls 12 and 13, and pressure is applied by the spring 5.

In FIG. 3, the pressure of the polishing rod 1 can be adjusted by the adjustment handle 6 with the slider 8 serving as a guide.

Referring to FIG. 3, the polishing rod 4 is
The reciprocating movement with respect to the surface 3 is performed by guiding the forward / reverse rotation of the drive motor 11 through the rack and pinion 10 with the slider 9.

In FIG. 1, the forward rotation of the drive motor 11
Switching of reverse rotation is performed by limit switches 1 and 2.

The pressure of the spring 5 in FIG. 3 may be an air cylinder or rubber.

The adjustment of the pressure by the adjustment handle 6 in FIG. 3 may be performed by a regulator when an air cylinder is used.

The transmission of the power of the rack and pinion 10 in FIG. 3 may be a bolt screw or the like.

The drive motor 11 in FIG. 3 may be an air cylinder or the like.

[0019]

Since the present invention is configured as described above, it has the following effects.

Roll polishing can be performed automatically at a constant pressure and a constant speed without relying on manual labor.

In addition, it is possible to eliminate the fatigue of a person and the unevenness of the surface after the polishing by a person, such as the conventional manual roll polishing.

In addition, by automatically polishing, there is no danger that a hand will be caught in the roll.
