Technical Field

[0001] This utility model relates to the field of rolling mill rolls, specifically a wear-resistant and corrosion-resistant rolling mill roll. Background Technology

[0002] Rolls are the main working parts and tools on a rolling mill that cause continuous plastic deformation of metal;

[0003] Currently, during the rolling process, the rolling rolls follow the rotating shaft, resulting in incomplete deformation of the material during rolling. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wear-resistant and corrosion-resistant roll includes a pressure roller and a worm gear. An end shaft is fixedly connected to the end face of the pressure roller. An inner roller is rotatably connected to the inner cavity of the pressure roller. The end shaft is fixedly connected to the inner roller. The pressure roller is rotatably connected to the right side of the outer wall of the inner roller. A rotating roller is fixedly connected to the end of the inner roller away from the end shaft. A bearing is fixedly connected to the left side of the outer wall of the rotating roller. A pressure roller is fixedly connected to the outer wall of the bearing. The end shaft is fixedly connected to the end of the rotating roller away from the inner roller.

[0007] As a further embodiment of this utility model: a worm is fixedly connected to the outer wall of the end shaft, the worm is engaged with the outer wall of the worm wheel, and a motor is installed at the power input end of the worm.

[0008] As a further embodiment of this utility model: an outer wheel 2 is installed on the outer wall of the end shaft 1, and the front end of the outer wheel 2 is fixedly connected to the outer wheel 1.

[0009] As a further embodiment of this utility model: a lead screw cylinder is installed at the connection between the outer walls of the first outer wheel and the second outer wheel, and a bearing mounting wheel is fixedly connected to the front end of the inner cavity of the lead screw cylinder.

[0010] As a further improvement of this utility model, a shaft disc is installed between the outer wheel two and the outer wall of the end shaft one.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model controls the operation of a motor, which drives a worm gear to rotate. An end shaft engaged with the outer wall of the worm gear drives the end shaft to rotate, causing a roller mounted on one end of the end shaft to rotate and roll on a track. The middle part of the object, located on the outer wall of the roller, is straightened. Pressure rollers 1 and 2, connected to the left and right sides of the outer wall of the roller, do not rotate with the roller and are used to press down on both ends of the object, thus shaping it. Its structure is more optimized and its design is more reasonable. Attached Figure Description
