Description

Technical Field

[0001] The utility model relates to the field of roll polishing positioning, and specifically relates to a positioning component for roll polishing. Background Technique

[0002] A roll is the main working component and tool on a rolling mill that causes continuous plastic deformation of metal. A roll mainly consists of three parts: a roll body, roll necks, and shaft heads. The roll body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. The roll necks are installed in bearings, and the rolling force is transmitted to the rolling mill frame through the bearing seats and the screw-down device. The drive-end shaft head is connected to the gear housing through a coupling shaft to transmit the rotational torque of the motor to the roll. The rolls can be arranged in the form of two-high, three-high, four-high or multi-high in the rolling mill frame. The roll needs to be polished to change the surface smoothness for subsequent processing.

[0003] In the prior art, when polishing a roll, in order to facilitate stable polishing of the roll, a positioning component is used to fix the roll, thereby avoiding the problem of roll offset during roll polishing.

[0004] However, traditional positioning mainly locates and clamps the roll up and down through two groups of clamping plates, which may make it inconvenient to rotate the positioned roll when polishing the end face of the roll. Therefore, the utility model proposes a positioning component for roll polishing to solve the above-mentioned technical problems. Content of the Utility Model
