Description

Technical Field

[0001] This utility model relates to the field of metal rolling mill technology, and more specifically, to a variable crown support roll for metal rolling mills. Background Technology

[0002] A rolling mill is a piece of equipment that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. Rolling mills can be classified according to the number of rolls, such as two-roll, four-roll, six-roll, eight-roll, twelve-roll, and eighteen-roll. According to the arrangement of the rolls, they can be classified as "L" type, "T" type, "F" type, "Z" type, and "S" type.

[0003] A search revealed an existing continuous rolling mill for metal plates, with publication number CN210231011U. This mill comprises two rolling mills arranged sequentially, one in front of the other. Each mill includes a frame and roll assemblies mounted on the frame. Each roll assembly includes two transversely arranged rolls with a rolling space between them. The rolling space on the preceding mill is higher than that on the following mill. At least three rollers are positioned between the two mills. Each roller has a support frame underneath it for supporting the roller and adjusting its height. A spacing adjustment structure is provided between the support frames to adjust the distance between the rollers. This method allows the metal plate rolled by the preceding mill to be transported to the rolling space of the following mill for further rolling, effectively reducing the labor intensity of workers.

[0004] The support rolls of metal rolling mills have inclined surfaces on their exteriors to adjust the convexity of the workpiece's outer surface. Assembly bearings are installed at both ends of the roll body. When the assembly bearings of the support rolls are connected to the drive end of the metal rolling mill, they are subjected to significant torque, and lack external auxiliary support components, resulting in poor performance. Therefore, we propose a variable convexity support roll for metal rolling mills to solve the aforementioned problems. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a variable crown support roll for a metal rolling mill. A reinforcing component is installed on the outside of the mounting shaft seat. After being fixedly connected to the mounting shaft seat by the driving component of the metal rolling mill, the reinforcing ring is pulled outward along the mounting shaft seat. The guide seat slides along the guide groove, and then the locking bolt is screwed relative to the positioning groove of the reinforcing ring. The insertion end of the locking bolt extends into the interior of the limiting groove, completing the locking and fixing of the reinforcing ring. At this time, the reinforcing ring reinforces the connection between the mounting shaft seat and the driving component of the metal rolling mill, improving the structural strength and torsional resistance, and extending the service life.
