Description

Technical Field

[0001] The utility model relates to the field of hot rolling line rolling equipment, in particular to a dial for a roll and a roll combination structure. Background Art

[0002] When grinding the working rolls of a hot rolling line, the rolls need to be placed on a roll grinder and a roll dial connected to the rolls. The roll dial is used by the roll grinder to drive the rolls.

[0003] In the existing technology, the axial driving force generated during the high-speed rotation of the driving roller causes the dial to often slide toward the tail side of the roller or disengage, causing the roller to stop rotating while the equipment driving the roller continues to rotate and feed, and a plane will be processed on the roller surface along the roller generatrix, causing damage to the roller and huge losses. Utility Model Content

[0004] The main purpose of the utility model is to provide a dial for a roll and a roll combination structure to solve the technical problems of axial sliding and falling of the working rolls of a hot rolling line.

[0005] To achieve the above-mentioned purpose, the present invention provides a dial and roller assembly structure for a roller, comprising:

[0006] A dial body, the dial body comprising a shaft sleeve and a toggle member, the toggle member being disposed on the shaft sleeve; the shaft sleeve having an axial hole for cooperating with the flat head of the external roller;

[0007] A structural plate is located on the working surface side of the toggle member in the dial body; the structural plate is fixed to the shaft sleeve and extends into the shaft hole to a position corresponding to the movable flat center of the external headstock faceplate;

[0008] Bolts are located on the shaft sleeve and are used to fix the shaft sleeve on the roller.

[0009] The dial body is installed on the flat head of the working roll and is tightened and adjusted by bolts. During operation, the axial driving force generated by the high-speed rotation of the roll driven by the grinder headstock claws causes the movable flat center of the headstock faceplate to contact the structural plate, pressing the dial tightly against the roll to prevent the dial from axial sliding and falling off.

[0010] In some embodiments, the sleeve has two bosses, and the two ends of the structural plate are respectively connected to the bosses. The bosses can increase the overlapping area between the roller and the dial.

[0011] In some embodiments, the height ratio of the boss to the shifting plate is 0.80 to 1.14:1; the shifting plate is the portion of the shifting member that engages with the external grinding headstock shifting claw. The rotation thrust of the grinding headstock shifting claw drives the shifting plate to rotate.

[0012] In some embodiments, the height of the boss is 100-120 mm.

[0013] In some embodiments, the number of the toggle members is two, and the two toggle members are centrally symmetrically distributed along the axis of the sleeve;

[0014] Any of the toggle members includes a connecting plate and the toggle piece; the connecting plate is connected to the outer periphery of the sleeve; the structural plate includes a rectangular, elliptical, or circular shape that can contact the movable flat top of the headstock disc.

[0015] In some embodiments, the toggle member further comprises:

[0016] The reinforcing rib is connected between the connecting plate and the toggle piece, and the rotational stability of the toggle piece is improved by the reinforcing rib.

[0017] In some embodiments, the reinforcing rib is located on the surface of the shifting plate facing away from the grinding headstock shifting claw, that is, the side of the shifting plate without the reinforcing rib is in contact with the grinding headstock shifting claw.

[0018] In some embodiments, the shifting piece has a curved surface that cooperates with the grinding headstock shifting claw. The shifting piece and the grinding headstock shifting claw cooperate with each other to rotate.

[0031] The embodiments of the present application provide a dial and roller assembly structure for a rolling mill, which solves the technical problems of axial sliding and falling of the working rollers of a hot rolling line in the prior art.

[0032] refer to Figure 1-Figure 2As shown, the present application discloses a dial for a rolling mill, comprising a dial body, a structural plate 20 and a bolt 13. The dial body comprises a sleeve 10 and a toggle, and the toggle is arranged on the sleeve 10. The sleeve 10 has an axial hole 14 that cooperates with the flat head of the external rolling mill 200. The structural plate 20 is located on the working surface side of the toggle in the dial body. The structural plate 20 is fixed to the sleeve 10 and extends to a position in the axial hole 14 corresponding to the external headstock faceplate movable flat top 120. The bolt 13 is located on the sleeve 10 and is used to fix the sleeve 10 on the rolling mill 200.

[0033] Roll 200 can be understood as a working roll in hot rolling. The flat head of the working roll is where the dial is mounted, and the shaft hole 14 of the sleeve 10 matches the flat head. Therefore, the shaft hole shape of the sleeve corresponds to that of the working roll, and the sleeve is nested outside the flat head of the working roll.

[0034] The toggle is the component of the dial body that contacts the grinder headstock's shifter 110, rotating the grinder's movable faceplate 100. The toggle's working surface is the portion of the toggle that contacts the grinder headstock's shifter 110 (e.g., the shifter pawl, which will be used as an example for ease of description), or the surface of the toggle facing the grinder headstock. Therefore, the structural plate is located on the side of the dial body facing the headstock's movable flat center, or on the side of the dial body facing the shifter pawl.

[0035] There are no specific requirements for the shape of the structural plate 20, such as rectangular, oval, or circular. One end of the structural plate 20 extends from a starting point on the outer periphery of the sleeve 10 above the shaft hole 14, and the other end can be connected in a variety of ways, as long as the structural plate 20 can contact the movable flat center 120 of the headstock faceplate when the dial is installed on the roller 200.

[0036] For example, the other end passes through the center of the shaft hole 14 and extends completely across the shaft hole 14 to a symmetrical point on the shaft hole 14. At this time, both ends of the structural plate 20 are on the outer periphery of the shaft sleeve 10. In this way, both ends of the structural plate 20 have support points and are connected to the shaft sleeve 10 as a whole. Therefore, the strength of the structural plate 20 is higher and the service life is improved.

[0037] As another example, the other end does not cross the axial hole 14 but extends only to a position where it can contact the movable flat tip 120 of the headstock faceplate, such as to the middle of the axial hole 14. In this case, one end of the structural plate 20 is located on the outer periphery of the sleeve 10, while the other end is suspended above the axial hole 14 of the sleeve 10. This structural plate arrangement is shorter in length, reducing material costs.

[0038] The bolts 13 are located on the sleeve 10 to fix the sleeve 10 on the roll 200. For example, the sleeve has a threaded hole, and the bolts are screwed into the threaded hole to make close contact with the flat head side of the working roll to form a fixation.

[0039] During operation, the dial body is installed on the flat head of the roller 200 and is tightened and adjusted by the bolt 13. During operation, the grinding machine head frame shifter 110 drives the roller 200 to rotate at high speed, generating an axial driving force. The head frame faceplate movable flat center 120 contacts the structural plate 20, pressing the dial tightly against the roller 200 to prevent the dial from axial sliding and falling.

[0040] The above-mentioned utility model provides a roller dial. A structural plate 20 is designed on the dial. The movable flat center 120 of the headstock faceplate is tightened against the flat end of the roller 200 via the structural plate 20, thereby solving the problem of axial slippage and fallout of the dial. Damage to the roller caused by slippage or fallout is avoided, and the installation method is simple and convenient.

[0041] In some embodiments, the sleeve 10 has two bosses 11, and the ends of the structural plate 20 are connected to the bosses 11. The bosses can increase the axial contact length between the roller and the dial, thereby increasing the bonding area between the roller and the dial, making the bond between the two more stable and less likely to wobble.

[0042] In some embodiments, the height ratio of the boss 11 to the shifting piece 30 is 0.80 to 1.14:1; the shifting piece 30 is the portion of the shifting member that engages with the external grinding headstock shifting claw 110. Exemplarily, the height of the shifting piece 30 is 105 to 125 mm.

[0043] The rotational thrust of the grinding headstock shifter 110 drives the shifting plate 30 to rotate. When the height of the boss 11 and the shifting plate 30 meet the above conditions, when the shifting plate 30 contacts the grinding headstock shifter 110, the structural plate 20 and the headstock faceplate movable flat center 120 are also substantially in contact, facilitating installation and adjustment and saving debugging time.

[0044] In some embodiments, the height of the boss 11 is 100-120 mm.

[0045] In some embodiments, the number of the toggle members is two, and the two toggle members are centrally symmetrically distributed along the axis of the sleeve 10;

[0046] Any of the toggle members includes a connecting plate 12 and the toggle piece 30; the connecting plate 12 is connected to the outer periphery of the sleeve 10; the structural plate 20 includes a rectangular, elliptical, or circular shape that can contact the movable flat top 120 of the headstock disc.

[0047] In some embodiments, the toggle member further comprises:

[0048] The reinforcing rib 31 is connected between the connecting plate 12 and the toggle piece 30. The reinforcing rib 31 is used to improve the rotation stability of the toggle piece.

[0049] In some embodiments, the reinforcing ribs 31 are located on the surface of the shifting plate 30 facing away from the grinding headstock shifter 110. That is, the side of the shifting plate without the reinforcing ribs contacts the grinding headstock shifter 110, thereby preventing the reinforcing ribs from interfering with the grinding headstock shifter 110, thereby improving the stability of the dial operation.

[0050] In some embodiments, the shifting plate 30 has a curved surface that mates with the grinding headstock shifting dog 110. The shifting plate and the grinding headstock shifting dog rotate in conjunction with each other. The grinding headstock shifting dog is a cylindrical structure, and the shifting plate's curved surface wraps around the cylindrical structure, increasing the contact area between the two. During operation, the shifting plate is less likely to slip, thereby improving the stability of the dial's operation.

[0051] In some embodiments, the shaft hole 14 is a waist-shaped hole, and the ends of the structural plate 20 are located on the corresponding straight edges of the sleeve 10. This arrangement allows the ends of the structural plate to be flush with the straight edges, creating a smooth surface and facilitating machining. Furthermore, the structural plate is shorter, and the length of the plate suspended above the shaft hole is shorter, resulting in greater strength.

[0052] The present application also discloses a roll assembly structure, comprising: a roll, a grinding machine headstock shifter, a grinding machine movable faceplate, a headstock faceplate movable flat center, and the above-mentioned dial for the hot rolling line working roll.

[0053] Since the above-mentioned roller combination structure includes the above-mentioned dial for the hot rolling line working roll, it also has the beneficial effects corresponding to the dial, such as the roller combination structure has the advantages of stable operation and high strength, which will not be described in detail.

[0054] The above technical solutions of the present invention are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
