Description
Technical Field
[0001] The utility model relates to the technical field of cold rolling mill working rolls, in particular to a wear-resistant cold rolling mill working roll. Background Art
[0002] A cold rolling mill is a device for installing working rolls. The working rolls need to be installed on a rotating machine. The rotation of the machine drives the roll surface to rub against the grinding object. The relative rolls can also be adjusted according to the grinding objects of different specifications. Patent publication number CN213256272U discloses a wear-resistant working roll of a cold rolling mill, including a frame and a fixed roll. A fixed plate is arranged on the top of the frame, and a rotating rod is arranged through the middle of the top of the fixed plate. A valve is installed on the top of the rotating rod, and a connecting rod is arranged at the bottom of the rotating rod. Clamps are arranged at the bottom of both ends of the connecting rod, and a moving roll is arranged on the outside of the clamp, and an anti-friction block is arranged on the outside of the moving roll. A fixed pad is arranged at the bottom of the clamp, a support cylinder is arranged at the bottom of the frame, and a support rod is arranged on the inner side of the support cylinder, and a rotating shaft is arranged at the bottom of the support cylinder. The fixed roll is arranged below the moving roll, and a rotating rod is arranged on the inner side of the fixed roll. The wear-resistant working rolls of the cold rolling mill are provided with anti-friction blocks, which are arranged on the outside of the moving rolls and are evenly distributed on the surface of the moving rolls. This ensures that the working rolls working for a long time will not wear out quickly, causing the working rolls to deform easily.
[0003] Although anti-friction blocks are used to protect the moving roller, the friction blocks will gradually become thinner with use and lose their protective effect. Since they are distributed on the surface of the moving roller by welding, they cannot be replaced separately when they lose their function and can only be replaced or re-welded together with the moving roller. The operation is cumbersome and has relatively high limitations, thereby reducing the practicability of the device. Utility Model Content

[0021] In the above embodiment, it should be noted that the two wear-resistant rings 501 are mounted by snap-fitting in a centrally symmetrical manner, so that they can wrap and protect the surface of the moving roller 2 .
[0022] The technical effect achieved by the above embodiment is: the synchronous groove 504 is used to achieve the overall synchronous rotation with the movable roller 2, ensuring that it is portable and easy to assemble and disassemble without affecting its anti-friction effect. Example
