Description

Roll support device for roll polishing equipment {A DEVICE FOR SUPPORTING ROLL OF ROLL GRINDING UNIT}

The present invention is a roll polishing facility used to grind a rolling roll after hot rolling, and the replacement of the jaw metal (JAW METAL) for mounting the roll due to the difference in the diameter of the journal (JOURNAL) according to the type of roll The roll supporting device of the roll polishing equipment which does not need to easily perform the grinding work by the roller bearing installed on the upper side of the NECK REST by automation, as well as the accurate roundness, which eliminates the need for regrinding. It is about.

In more detail, the support body is installed to be moved by the drive unit on the upper side of the base, and an adjustment gear insertion hole is formed on the upper side thereof, and the adjustment gear which protrudes the adjustment gear inside the control gear insertion hole is inserted into the body. One end thereof is connected to a cylinder coupled to the support body, and a roller support plate is integrally formed with the roller support to the support body, and a roller block to which the roller bearing is coupled is inserted into the roller support to adjust its bottom. It is characterized in that it is in close contact with the gear.

In a generally known roll polishing facility, as shown in FIG. 1, the headstock 140 and the tailstock 150 having the center 130 installed to support the roll 120 above the base 110 are provided. Is installed, the support 170 is installed so that the upper and lower coarse metal (160A, 160B) is installed to support the journal 190 of the roll 120 to the upper side of the base 110, the upper The lower coarse metal 160A and 160B are movable as adjustment levers 180A and 180B connected to one side thereof.

As shown in FIGS. 1 and 2, the roll polishing apparatus of the conventional roll polishing equipment associated with such a technique may have different diameters of the journal 190 for each kind of the roll 120 during the polishing operation of the roll 120. Therefore, in order to support the roll 120, the upper and lower coarse metals 160A and 160B installed on the support 170 so as to match the diameter of the journal 190 must be replaced manually by using the crane 200. After the replacement of the rough metals 160A and 160B, the roll 120 is seated on the polishing machine to perform polishing. When the cylindricalness and the roundness of the roll 120 do not coincide, the adjustment levers 180A and 180B are used. The operation is made of a configuration to perform the calibration operation of the coarse metal (160A) (160B).

However, in the roll polishing apparatus as described above, the coarse metal, which is a heavy material, must be exchanged manually by separate co-metals 160A and 160B formed to match the diameters of the different journals 190 for each roll 120. Safety accidents such as being squeezed on (160A) (160B) or fall of the metal roughly occur frequently, and the work time is increased.

In addition, since the cylindricalness and roundness are not exactly matched after the roll 102 is mounted on the coarse metals 160A and 160B, a separate coarse metal zeroing operation is to be performed to increase worker fatigue as well as a lot of working time. There is a lot of problems, such as difficult to control the rolling thickness due to the non-uniform friction of the journal 190 is difficult to adjust the precise zero of the coarse metal (160A) (160B).

The present invention is to improve the various conventional problems as described above, its purpose is to adjust the height of the roller bearing supporting the journal to the automation does not need to replace it, thereby preventing the occurrence of safety accidents in advance, The roller bearing supports the journal precisely, enabling precise grinding of the rolls, which contributes to quality improvement through the rolling sheeting and uniform thickness control, and significantly shortens the working time by automation, and makes uniform contact between the roller bearing and the journal. The present invention provides a roll support device for a roll polishing machine that can extend the life of a roll.

As a technical configuration for achieving the above object, the present invention, the support is installed on the bottom of the support body which is installed in close contact with the upper side of the base of the polishing apparatus, the support is formed integrally with the adjustment gear insertion hole on the upper side;

A roller is provided in the control gear insertion hole so that the control gear protruding from the upper side is inserted into the adjusting gear insertion hole, and one end of the control gear body is connected to the cylinder coupled to the support body;

A roller support having a through hole formed integrally with an upper side of the roller support plate coupled to the support body, and a roller support having a roller block into which a roller bearing is integrally installed inside the through hole of the roller support. The roller bearing in close contact with the journal of the roll is installed so as to move up and down during the operation of the cylinder, so that the roll supporting device of the roll polishing equipment can be easily installed regardless of the journal diameter of the roll.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a schematic view showing a roll support of the roll polishing apparatus according to the present invention, Figure 4 is a side schematic view showing a roll mounting state according to the present invention, Figure 5 is a combination showing a roll supporting device according to the present invention As a state diagram, this design consists of the support stand 1, the roller lifting part 2, and the roller support part 3. As shown in FIG.

The support 1 which is provided to be in close contact with the upper side of the base 5 of the polishing apparatus has a rack formed at one side of the base 5 at the bottom of the support body 6 whose bottom is formed to be in close contact with the upper part of the base 5. The driving unit 8 is fitted to the 7 to move, and the hemispherical adjustment gear insertion hole 9 is integrally formed on the upper side of the support body 6, and the driving unit 8 includes a support body ( 6, the worm 11 of the motor 10 is coupled to the worm wheel 13 is fitted with the pinion 12 is integrally formed.
