[0002]In the stainless steel cold rolling industry, when the rolling mill is rolling stainless steel strips, the work rolls are rotating at high speed. For safety reasons, baffles or valves are generally used to block the work rolls At both ends, the work rolls are not allowed to move in the axial direction. At present, the baffles are generally opened or closed manually, and then the baffles are pressed against the jacking cylinder. The bearings are installed in the jacking cylinder to cooperate with the work rolls, and the baffles are pressed against the work rolls. , but the pressure of the top pressure of the baffle is not easy to adjust, and the bearing in the top cylinder is easily damaged

Embodiment Construction
[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention.
[0023] see figure 1 According to the first preferred embodiment of the present invention, the pressing device used to prevent the axial movement of the work rolls of the rolling mill includes a swing arm structure 10 and a pressing structure 20 installed on the swing arm structure 10. The pressing structure 20 together with the swing arm structure 10 Swing to the preset position to press the end face of the working roll of the rolling mill to prevent the axial movement of the working roll of the rolling mill.
[0024] The swing arm structure 10 includes a swing arm 11 and a rotating shaft 12 fixedly connected to one end of the swing arm 11 . Specifically, the rotating shaft 1...

The invention provides a pressing device for preventing the axial play of a working roller of a rolling mill. The pressing device comprises a swinging arm structure and a pressing structure, wherein the swinging arm structure comprises a swinging arm capable of swinging around one end; the pressing structure comprises a mounting frame and a pressure roller structure; the mounting frame is arranged on the swinging arm, and swings along with the swinging arm; the pressure roller structure is arranged on one side of the mounting frame, and comprises a pressure roller and a driving component; the pressure roller is driven by the driving component to extend and contract relative to the mounting frame. According to the pressing device, the pressing structure is arranged on the swinging arm structure, and the swinging arm structure can rotate to a preset position to press the pressure roller of the pressing structure against the working roller of the rolling mill, so that the axial play of the working roller during work is avoided; moreover, the pressure roller is arranged on one side of the mounting frame at an adjustable distance, and the pressure of the pressure roller relative to the working roller can be adjusted, so that the pressure roller can be effectively protected.
Description
technical field [0001] The invention relates to the stainless steel cold rolling industry, in particular to a pressing device for preventing axial movement of work rolls of a rolling mill. Background technique [0002] In the stainless steel cold rolling industry, when the rolling mill is rolling stainless steel strips, the work rolls are rotating at high speed. For safety reasons, baffles or valves are generally used to block the two ends of the work rolls to prevent the work rolls from moving in the axial direction. The baffle is opened or closed manually, and then the baffle is pressed against the jacking cylinder. There are bearings in the jacking cylinder to cooperate with the work rolls, so that the baffle presses the work roll tightly. However, the pressure of the baffle is not easy to adjust. Bearings are easily damaged. Contents of the invention [0003] In view of the above, it is necessary for the present invention to provide a compacting device for preventing...
