Description

Technical Field

[0001] This utility model relates to the technical field of steel rolling mill processing equipment, and in particular to a tension pad device for steel rolling mills. Background Technology

[0002] In high-speed rolling, variations in strip thickness can cause tension fluctuations, affecting product quality. Existing technology addresses this by installing tension pads on the upper and lower stands of the steel rolling mill. During rolling, these tension pads are pressurized by hydraulic cylinders to generate the required tension. The device controls the tension by adjusting the pressure, thus precisely compensating for tension fluctuations caused by changes in strip thickness during rolling, achieving fine-tuning of the tension. Existing tension pad installation structures (such as...) Figure 1-2 As shown, all are fixed to the upper and lower frames with bolts. This installation and fixing method has the following disadvantages: (1) The point fixing method provided by bolts is less stable than surface contact and is prone to loosening under long-term impact load; (2) The tension pad located below is prone to warping and deformation after being subjected to force due to the slot design, which leads to jamming during replacement and maintenance difficulties. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a tension pad device for steel rolling mills, which solves the issues of poor stability of the tension pad installation structure, easy deformation under stress, and inconvenience in disassembly and replacement in the prior art.

[0004] The specific technical solution is as follows: A tension pad device for a steel rolling mill includes an upper base disposed at the bottom of an upper frame, a lower base disposed on a lower frame, a drive cylinder, and a tension pad. The drive cylinder is disposed on the upper frame and drives the upper base to move up and down. The bottom of the upper base and the top of the lower base are respectively provided with mounting grooves for mounting the tension pad. One side of the mounting groove is open and has a detachable pressure plate. The upper end of the side wall of the mounting groove and the upper end of the side wall of the pressure plate are respectively provided with corresponding limiting ends, making the cross-section of the mounting groove T-shaped. The side wall of the tension pad is stepped and has a protrusion. The protrusion of the tension pad cooperates with the limiting end on the side wall of the mounting groove to realize the longitudinal limiting of the tension pad by the mounting groove.

[0005] Furthermore, the number of mounting slots on both the upper and lower bases is at least two, and the mounting slots are arranged horizontally.

[0006] Furthermore, the positions of the tension pads on the upper base and the lower base correspond one-to-one.

[0007] Furthermore, the upper base is provided with guide columns at both ends of the top, and the upper ends of the two guide columns pass through both ends of the upper frame respectively.

[0008] Furthermore, the pressure plate is horizontally threaded through by bolts and connected and fixed to the upper base and the lower base respectively.

[0009] Furthermore, the tension pad includes a bearing substrate and a covering layer covering the surface of the bearing substrate.

[0010] The beneficial effects of this utility model are reflected in: This invention features a detachable pressure plate on one side of the mounting groove of the upper and lower bases. The tension pad is fixed in place by the cooperation of the pressure plate with the side wall of the mounting groove, making it easy to disassemble and replace.

[0011] In this invention, the limiting end on the side wall of the mounting groove cooperates with the protrusions around the tension pad to achieve surface contact positioning of the tension pad, which can effectively prevent the tension pad from loosening and deforming.
