Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold rolling mills, in particular to a guide device for a steel strip cold rolling mill. Background Art
[0002] Cold rolling uses hot-rolled products as raw materials. Prior to cold rolling, the raw materials must be dephosphorized to ensure a clean surface. Rolling is the primary process that deforms the material. Continuous cold rolling deformation causes work hardening, which increases the material's strength and hardness while decreasing its toughness and ductility. Cold rolling mills are the primary machinery in the cold rolling process and are widely used in metal smelting and processing.
[0003] In order to make steel strips of different widths consistent with the center of the roller, traditional steel strip cold rolling mills often need to insert unevenly thick steel pads in the width direction of the cold rolling mill inlet. To produce steel strips of different widths, different pads need to be replaced. This is not only cumbersome to operate in practice, but also has low guiding accuracy. Utility Model Content

[0026] like Figure 1-Figure 4As shown, a guide device for a steel strip cold rolling mill in one embodiment of the present invention includes a frame 1 and a guide mechanism; two limit members 2 are slidably mounted on the frame 1, and the gap between the two limit members 2 forms a limit space for the limited steel strip, and the limit member 2 can move up and down relative to the frame 1; the guide mechanism includes an adjustment component 3, a guide roller 4 and a mounting seat 5 detachably mounted on the limit member 2, the adjustment component 3 is installed in the mounting seat 5 and is used to drive the guide roller 4 to slide relative to the mounting seat 5, and the surface of the guide roller 4 is provided with a roller sleeve 41 for abutting the steel strip.
[0027] The above-mentioned steel strip cold rolling mill guide device is provided with two limit members 2, and the two limit members 2 can slide separately, so that the limit space between the two limit members 2 can be adjusted at any time, which is conducive to adapting to steel strips of different widths. There is no need to replace different pads, which reduces processing costs, and the limit members 2 can be raised and lowered, so as to facilitate the adjustment of the conveying height of the steel strip and adapt to the inlets of cold rolling mills with various height settings; by providing a guide roller 4, it plays a guiding role for the steel strip entering the cold rolling mill; by providing a roller sleeve 41, in the process of continuous contact between the guide roller 4 and the steel strip, when the guide roller 4 is worn, only the outer roller sleeve 41 needs to be replaced, thereby reducing the later maintenance cost.
[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the frame 1 includes two support bases 11 and a transverse guide rail 12 connected between the two support bases, and a lifting guide rail 13 is mounted on the support base 11.
[0029] Specifically, the transverse guide rail 12 is arranged in a horizontal direction; and the lifting guide rail 13 is arranged in a vertical direction.
[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a lifting member 14 is slidably mounted on the lifting guide rail 13. The sidewalls of the lifting member 14 are provided with insertion holes, and the two ends of the transverse guide rail 12 are respectively inserted into the insertion holes of the two lifting members 14. Thus, by providing the lifting members 14, the lifting and lowering movement of the lifting members 14 on the lifting guide rail 13 can drive the transverse guide rail 12 to also move up and down, thereby controlling the height adjustment of the position limiter 2.
[0031] like Figure 1 and Figure 2As shown, in one embodiment, the support base 11 is further mounted with a rotating shaft located on one side of the lifting guide rail 13. A lifting screw 15 is rotatably mounted on the rotating shaft. The lifting member 14 has a built-in first threaded guide structure. The lifting screw 15 is inserted into the interior of the lifting member 14 and is threadedly connected to the first threaded guide structure. One end of the lifting screw 15 passes through the lifting member 14 and extends above the lifting member 14. By rotating the lifting screw 15, the lifting member 14 can be driven to move up and down through the threaded connection between the lifting screw 15 and the first threaded guide structure.
[0032] like Figure 1 and Figure 2 As shown, in one embodiment, a transverse screw rod 16 is rotatably connected between the two lifting members 14. Both of the two limiting members 2 are built with a second threaded guide structure. The transverse screw rod 16 is inserted into the limiting member 2 and threadedly connected to the second threaded guide structure. By rotating the transverse screw rod 16, the threaded connection between the transverse screw rod 16 and the second threaded guide structure can drive the limiting member 2 to slide horizontally on the transverse screw rod 16.
[0033] like Figure 3 As shown, in one embodiment, a mounting groove 51 is opened in the mounting seat 5; the adjustment assembly 3 includes a sliding member 31 and an adjusting screw 32 rotatably assembled in the mounting groove 51, the sliding member 31 has a built-in third thread guide structure, the adjusting screw 32 is inserted into the sliding member 31 and is threadedly connected to the third thread guide structure, and the guide roller 4 is mounted on the top of the sliding member 31 and can rotate relative to the sliding member 31.
[0034] Specifically, the transverse screw rod 16 and the adjusting screw rod 32 are both arranged horizontally and perpendicular to each other.
[0035] like Figure 3 As shown, in one embodiment, the adjustment assembly 3 further includes a drive motor 33 mounted on the mounting base 5. The output end of the drive motor 33 extends into the mounting slot 51 and is in transmission connection with the adjustment screw 32. The drive motor 33 controls the rotation of the adjustment screw 32, which in turn drives the guide roller 4 to slide horizontally on the adjustment screw 32 through the threaded connection between the adjustment screw 32 and the third threaded guide structure.
[0036] like Figure 3 As shown, in one embodiment, the number of sliding members 31 and the number of guide rollers 4 are both multiple, and the two correspond one to one. The provision of multiple guide rollers 4 can adapt to steel strips of different lengths and enhance their guiding effect on the steel strips.
[0037] like Figure 1 and Figure 4As shown, in one embodiment, a first splicing groove 42 is formed on the outer surface of the guide roller 4, a second splicing groove 43 is formed on the inner curved surface of the roller sleeve 41, and a connecting plug 44 is provided between the guide roller 4 and the roller sleeve 41. One end of the connecting plug 44 is inserted into the first splicing groove 42, and the other end of the connecting plug 44 is inserted into the second splicing groove 43. The connection between the guide roller 4 and the roller sleeve 41 is fixed by providing the connecting plug 44.
[0038] like Figure 1 and Figure 4 As shown, in one embodiment, a connecting support structure 45 is further provided between the guide roller 4 and the roller sleeve 41.
