Description

Technical Field

[0001] The utility model relates to the technical field of rolling rolls, in particular to a replaceable rolling roll. Background Art

[0002] A rolling roll is the working part of a rolling mill that causes plastic deformation of the metal being rolled. The shape, size, and material of the rolling roll must be adapted to the rolling mill and the rolled product. The roll sleeve is the working part of the rolling roll. The rolling roll is an important part of the rolling mill in a steel rolling plant, and it mainly bears the static and dynamic loads, wear, and temperature changes during rolling.

[0003] After retrieval, Chinese Patent Publication No.: CN208758337U discloses a combined rolling roll, which includes a roll body, roll necks, and a shaft head. The roll body includes a left half roll body and a right half roll body, and the two can be assembled by means of threaded connection. Insert the handle into the groove and apply manual force to tightly connect the left half roll body and the right half roll body, or assemble them by means of a snap connection. When the cylinder slides into the storage groove through the chute, the left half roll body or the right half roll body needs to be rotated, and the protruding mechanism can freely expand and contract until the round hole on the cylinder completely coincides with the protruding mechanism, that is, when you hear a "pop" sound, it means that the assembly of the left half roll body and the right half roll body is completed. When it is necessary to replace the left half roll body or the right half roll body, press the button switch, then the protruding mechanism retracts, and then it can be replaced, or assemble them by means of extrusion.

[0004] The above device has the following defects: after the rolling roll is used for a period of time, the surface is worn, resulting in unusability. When it is necessary to replace the roll sleeve purchased differently, it is necessary to repurchase the entire set of equipment, which reduces the work efficiency and increases the cost.

By providing the pull plate 42, it is convenient for personnel to operate and move. One end of the first movable rod 44 away from the pull plate 42 is hinged to a first arc-shaped plate 45, a second movable rod 46 is hinged to the inner side wall of one side of the pull plate 42, and one end of the second movable rod 46 away from the pull plate 42 is hinged to a second arc-shaped plate 47. Ring openings 48 are provided on the inner side walls of both sides of the adjusting disk 41. By providing the ring openings 48, the roll shaft 1 is sleeved.

[0025] Referring to Figures 2-3 , there are two adjusting disks 41 in total. The two adjusting disks 41 are respectively attached to and connected to the outer side walls of both sides of the roll sleeve 3. One end of the telescopic spring 43 away from the pull plate 42 is fixedly connected to the inner side wall of one side of the adjusting disk 41. A frosted pad is fixedly connected to the outer side wall of the pull plate 42. The first arc-shaped plate 45 is slidably connected to the inner side wall of one side of the adjusting disk 41. By providing the cooperation between the first arc-shaped plate 45 and the second arc-shaped plate 47, the adjusting disk 41 is clamped and pressed against the outer side walls of both sides of the roll sleeve 3.
