Expansion Type Wringer Roll And Grinding Apparatus Therefore}
[19] The present invention relates to an expandable ringer roll that removes moisture remaining on a strip surface during a cold rolling and plating process, and more particularly, to an upper roll and a lower roll that are completely in front of the strip regardless of the thickness of the strip. An inflatable ringer roll that closes the moisture and makes contact with the strip face-to-face by the tire of the roll, and an expandable ringer roll that can double the effect of squeegeeing, and an inflatable ringer that separates, transports, and grinds the tire. A polishing apparatus for a roll.
[20] Generally, two or three squeegee ringer rolls are installed at the end of all chemical equipments in cold rolling and plating lines and three or four squeegees are used at the end to push the water and chemicals remaining on the strip surface to the side of the strip. Squeezing is performed.
[21] In the related art, as shown in FIGS. 5A and 5B, the upper roll 1a and the lower roll 1b of the ringer roll 1 are closed to prevent water from the front and rear surfaces of the strip 2 from traveling with the strip. It consists of the structure which squeezes by.
[22] However, in the conventional ringer roll configured as described above, the water on the strip surface falls to both sides of the strip, and as shown in FIG. 5B, the portions on which the strips on both sides of the ringer roll do not reach the upper roll 1a and the lower roll 1b by the thickness of the strip. ) Do not touch each other so that the water in this area is still spreading on both sides of the strip passing through the ringer roll (1), as the roll (1) rotates and is pushed into the strip by "A" in Figure 5b. The water will remain and require the next squeegee.
[23] However, even after repeating 2-3 squeezing, edge wiping is performed to remove moisture remaining on both sides of the strip, but if the strip is thick (over 1.5t) or the line speed is high, the ringer roll Even after passing through the edge wiping, water remained on both sides of the strip and rust was generated during product storage and transportation.
[24] In addition, since the welding part welds the front coil and the rear coil by 2 ~ 3mm overlap, the thickness of the welding part is twice as much as the strip where the welding part progresses, and it cuts the ringer roll pressed by the air cylinder at the top when passing the welding part, thereby shortening the exchange life of the roll. In addition, due to working air such as roll polishing, coating, and BRG assembly, it is necessary to secure and operate 4 to 10 spare parts to install 4 ringer rolls. In the case of a heavy load of more than 300kg for the purpose of polishing the surface of the roll was difficult to produce a problem.
[25] The present invention has been made in view of the above problems, and regardless of the thickness of the strip, the upper roll and the lower roll are completely adhered to the front of the strip to remove moisture, and the contact with the strip is brought into surface contact by the tire of the roll. It is an object of the present invention to provide an expandable ringer roll capable of doubling the effect of squeegee and an expandable ringer roll polishing device capable of only separating, transporting and polishing tires.

[42] 3 is an exploded perspective view of the polishing apparatus according to the present invention, Figure 4 is a cross-sectional view of the polishing apparatus according to the present invention, the polishing apparatus is a device for polishing the tire in the polishing machine by separating the tire from the roll, the core shaft 36 is The shaft on one side of the hollow is formed in the air supply vent hole is drilled to the outer peripheral surface.
[43] The check valve 37 is assembled to the vent hole, and the inside of the hollow is formed in two stages, so that the air line connection pipe 39 is assembled therein. The air cylinder 35 of the rod-side circular flange type is bolt-assembled, the other end of the mandrel 36 has two symmetrical protrusion structures, and a spiral hole is formed at the end surface thereof, assembled with the end shaft 33, and a key groove is formed at the outer circumferential surface thereof. And assembled to the sleeve 30 together with the key 36a.

And the sleeve 30 is moved forwards and backwards, and one segment 34 is assembled on each of the outer peripheral surfaces of the sleeve in the " T " sliding surface, and an end shaft 33 is formed at one end of the segment. Bolts are assembled.
[45] In the above, the end shaft 33 which fixes the mandrel 36 and expands to the outside by preventing the segment 34 from moving forward when the sleeve 30 is advanced by the cylinder 35 has a circular shape for fixing the grinding material. The shaft is formed on one side of the plate, the elastic lava sleeve 38 is assembled on the outer circumferential surface of the segment 34 so that the tire can be polished in the circular state possible, and the segment (when rotating the polishing apparatus) 34) to prevent separation and separation.
[46] The outer circumferential ends of the lava sleeve 38 are formed with a “U” shaped notch that matches the jaw of the inner ring fixing portion of the tire to prevent excessive polishing due to the fixing jaw of both end surfaces of the tire during polishing.
[47] Looking at the working relationship of the present invention as follows.
[48] When the tensioning nut (11) is removed by turning the tension adjusting nut (11) during the exchange cycle of the ringer roll, the adjusting ring (12) moves inward of the ringer roll, and the tension of the tire (16) is released while the tension of the compression spring (17) is turned off. Then, the touch roll 15 fixed by the male screw of the flange 13 and the female screw of the lock nut 14 is disassembled, and the tire 16 is taken out.
[49] Only the removed tire 16 is transported to a polishing place, mounted on a polishing apparatus and polished. When air is introduced through a check valve 37, air is connected to a header cover of the air cylinder 35 through a connecting pipe 39. Air is delivered to advance the piston, which simultaneously advances the sleeve 30 fixed by the cylinder rod 35a and the nut 32 and also advances the segment 34 fixed to the sleeve 30, the segment being end It is blocked by the shaft 33 and fails to advance and extends to the outer circumferential surface along the "T" shaped sliding surface of the sleeve.
[50] When the expansion is completed, the air line supplied with air is connected to the check valve 37, and the grinding operation is performed in the expanded state. At this time, the grinding operation takes about 5 to 7 minutes. You don't have to worry about it.
[51] When the polishing operation is completed and the air valve is locked by the check valve 37, the piston is returned to its original position by the spring 17 inside the air cylinder 35, and when the expanded segment 34 is reduced, the tire 16 which has been polished is completed. To disassemble and transport the tire 16 to the ringer roll, and to contact each other when the upper and lower rolls are closed, to prevent wear of the tire, and then to fix the tire 16. 15) and the nut for fixing the touch roll (15).
[52] The assembled ringer roll adjusts the tire 16 loosened by the adjusting nut 11, and the adjusting nut 11 and the adjusting ring 12 are tabbed to each other, so that when the adjusting nut 11 is adjusted, the tire The flange 13, which is assembled with the spline gear of the adjustment ring 12 while fixing the 16 and the touch roll 15, is pushed outward of the roll under tension of the compression spring 17 to tighten the tire 16. Let's do it.
[53] Once the adjustment is complete, the ringer roll is mounted on the facility when it is time to replace the roll. The mounted roll is supplied with air to the roll cell 10 through the rotary cylinder, and supplied to the tire 16 through the vent hole of the roll cell 10 to inflate the tire 16, which touches the tire 16. The uneven protrusions of the flange 13 fixing the roll 15 and the uneven protrusions at both ends of the roll cell 10 overlap each other as much as the compression spring 17 allows, thereby providing a space for the tire 16 to expand. Secure it.
[54] When the upper roll is closed to the lower roll to squeeze the strip, the touch roll 15 abuts against each other and prevents the tire 16 from contacting the roll cell 10 and wears itself, thereby expanding the upper and lower rolls. The tire 16 squeezes abutting the entire area of the strip and the area where the tire 16 is expandable, as shown in FIG. 2B.
[55] As described above, the present invention expandable ringer roll and its polishing apparatus can improve squeegeeing because the contact surface with the strip is in contact with the tire inflated by air, and the strips are not exposed to the strips on both sides of the roll. With the expansion of the tire, the entire area of the ringer roll is driven by the upper roll and the lower roll in contact with each other, so it is completely squeezed and the elasticity of the tire does not hurt the tire even when passing through the weld. It is easy to carry and handle because only the tires are separated and transported for transportation, and securing enough tires for one ringer roll main body is enough to prepare spare parts, which is expensive, heavy and occupy a large area. It is a very useful invention that does not have to be secured by the concept of a set.
