Technical Field
[0001] This utility model relates to the field of rolling mill equipment technology, specifically to a rolling mill forming equipment for steel billet rolling. Background Technology
[0002] In the steel rolling process of the metallurgical industry, the billet mill is the initial forming equipment. Traditional billet mills usually use fixed frames with rolls, or their roll gap adjustment mechanism is relatively complex, and they mostly rely on manual or large hydraulic systems for coarse adjustment, which has the problems of low adjustment accuracy and slow response speed.
[0003] When rolling steel billets of different specifications or materials, changing or adjusting the rolls is a heavy and time-consuming task, requiring machine shutdown and the use of special tools for tightening, which seriously affects the continuity of the production line. Traditional roll drive methods often transmit power through long shaft systems or complex gearboxes, resulting in bulky equipment structures, long transmission chains, and high energy losses. Furthermore, when the roll position needs to be adjusted, the drive components are difficult to move synchronously and accurately, which can easily lead to transmission failure or poor gear meshing, affecting rolling stability. To address the shortcomings of existing technologies, this utility model provides a rolling forming equipment for steel billet rolling mills to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rolling forming device for a steel billet rolling mill. By setting paired roll bodies on a guide rail frame with electric push rods and supported by a movable frame, it achieves rapid and precise electric adjustment of the overall height of the rolls, effectively improving adaptability to steel billets of different thicknesses. The installation unit can adjust the spacing of the bearing seats, which not only achieves precise alignment and stable positioning of the roll shaft, but also makes the installation and disassembly of the rolls convenient. The drive components are directly integrated into the movable frame, ensuring that the drive relationship remains consistent when the position of the roll body changes, and the transmission path is short, stable and reliable.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel billet rolling mill forming equipment, including a frame, a guide rail frame fixedly connected to the frame, and a pair of adjustable roll bodies on the guide rail frame, the roll body including an upper roll and a lower roll;
[0006] An electric push rod is fixedly connected to the guide rail frame, and a movable frame for supporting the main body of the roll is fixedly connected to the output end of the electric push rod.
[0007] The movable frame is equipped with a bearing seat for limiting the position of the roll body and an installation unit for adjusting the position of the bearing seat.
[0008] The movable frame is equipped with a drive assembly for driving the main body of the roll to rotate.
[0009] Preferably, a roll shaft is provided at the center of the main body of the roll, a driven gear is fixedly connected to the roll shaft, and the roll shaft is inserted into the bearing housing.
[0010] Preferably, the driving component includes:
[0011] The second motor is fixedly connected to the movable frame;
[0012] The driving gear is fixedly connected to the output end of the second motor. When the roll body is in the installation position, the driving gear and the driven gear are in a meshing state.
[0013] Preferably, the mounting unit includes:
[0014] The guide rod is fixedly connected to the movable frame;
[0015] An adjusting block, slidably connected to the guide rod, is used to provide an installation position for the bearing housing;
[0016] The first motor is fixedly connected to the movable frame;
[0017] A bidirectional screw is located at the output end of the first motor and threadedly connected to the adjusting block. When the first motor drives the bidirectional screw to rotate, it causes the distance between the adjusting block and the bearing seat to change, thereby achieving the limiting and disassembly of the roll body.
[0018] Preferably, a positioning plate is fixedly connected to the adjusting block, and a mounting plate is fixedly connected to the bearing seat, wherein the mounting plate is detachably connected to the positioning plate.
[0019] Preferably, the movable frame is slidably connected to the guide rail frame.

[0021] The technical effects and advantages of this utility model are as follows:
[0022] This steel billet rolling mill forming equipment achieves rapid and precise electric adjustment of the overall height of the rolls by setting the paired roll bodies on a guide rail frame with electric push rods and supported by a movable frame. This effectively improves the adaptability to steel billets of different thicknesses. The installation unit can adjust the spacing of the bearing seats, which not only achieves precise alignment and stable limiting of the roll shaft, but also makes the installation and disassembly of the rolls convenient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] This embodiment discloses a rolling and forming equipment for a steel billet rolling mill, according to the appendix... Figure 1 To be continued Figure 6As shown, the machine includes a frame 1, a guide rail frame 2 fixedly connected to the frame 1, and a pair of adjustable roll bodies 3 on the guide rail frame 2. The roll bodies 3 include an upper roll 31 and a lower roll 32. An electric push rod 21 is fixedly connected to the guide rail frame 2, and a movable frame 22 for supporting the roll bodies 3 is fixedly connected to the output end of the electric push rod 21. The movable frame 22 is provided with a bearing seat 4 for limiting the position of the roll bodies 3 and an installation unit 5 for adjusting the position of the bearing seat 4. The movable frame 22 is provided with a drive assembly for driving the roll bodies 3 to rotate.
[0033] According to the appendix Figure 1 and attached Figure 2 As shown, the movable frame 22 is slidably connected to the guide rail frame 2. The movable frame 22 can be moved up and down along the guide rail frame 2 by the extension and retraction of the electric push rod 21, thereby adjusting the overall height of the roll body 3 to accommodate rolling materials of different thicknesses. Furthermore, the guide rail frame 2 has circular holes corresponding to the movable frame 22 to provide sliding guidance and stable support for the movable frame 22, ensuring accuracy during the rolling process.
[0034] According to the appendix Figure 2 Appendix Figure 4 and attached Figure 5 As shown, a roll shaft 33 is provided at the center of the roll body 3, and a driven gear 34 is fixedly connected to the roll shaft 33. The roll shaft 33 is inserted into the bearing seat 4. The drive assembly includes a second motor 6 and a drive gear 61. The second motor 6 is fixedly connected to the movable frame 22, and the drive gear 61 is fixedly connected to the output end of the second motor 6. When the roll body 3 is in the installation position, the drive gear 61 and the driven gear 34 are in a meshing state, thereby driving the drive gear 61 to rotate through the second motor 6, which in turn drives the driven gear 34 and the roll shaft 33 to rotate, realizing the rotation control of the upper roll 31 and the lower roll 32, and completing the rolling operation.
[0035] According to the appendix Figure 3 Appendix Figure 5 and attached Figure 6 As shown, the installation unit 5 includes a guide rod 51, an adjusting block 52, a first motor 53, and a bidirectional screw 54. The guide rod 51 is fixedly connected to the movable frame 22, and the adjusting block 52 is slidably connected to the guide rod 51 and is used to provide an installation position for the bearing seat 4. The first motor 53 is fixedly connected to the movable frame 22, and the bidirectional screw 54 is located at the output end of the first motor 53 and threadedly connected to the adjusting block 52. When the first motor 53 drives the bidirectional screw 54 to rotate, it drives the adjusting block 52 to move relative to or towards the guide rod 51, thereby changing the distance between the adjusting block 52 and the bearing seat 4, and realizing the limiting and disassembly of the roll body 3. Furthermore, a positioning plate 521 is fixedly connected to the adjusting block 52, and an installation plate 41 is fixedly connected to the bearing seat 4. The installation plate 41 is detachably connected to the positioning plate 521, for example, by bolts, to facilitate quick installation and replacement of the bearing seat 4.
[0036] According to the appendix Figure 1 To be continued Figure 6 As shown, the movable frame 22 can move flexibly on the guide rail frame 2 via the drive of the electric push rod 21. Combined with the position adjustment of the bearing seat 4 by the mounting unit 5, the spacing and height of the roll body 3 are adjustable, thereby adapting to the needs of different specifications of steel billet. The drive assembly, through gear meshing, ensures the synchronicity and stability of the rotation of the roll body 3, improving rolling efficiency.
[0037] According to the appendix Figure 1 To be continued Figure 6 As shown, it is particularly important to emphasize that the mounting unit 5 adopts a bidirectional screw 54 and guide rod 51 structure, and achieves automatic adjustment through the first motor 53, making operation convenient. It is also particularly important to emphasize that the detachable connection design between the bearing housing 4 and the adjusting block 52 facilitates the maintenance and replacement of the bearing housing 4.
[0038] Example 1: This example uses a rolled standard steel billet as an example, combined with the attached... Figure 1 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows:
[0039] First, based on the billet thickness, the height of the movable frame 22 is adjusted by the electric push rod 21 so that the gap between the upper roll 31 and the lower roll 32 is adapted to the billet inlet.
[0040] Then, the first motor 53 of the installation unit 5 drives the bidirectional screw 54 to rotate, adjusts the spacing of the adjusting block 52, thereby adjusting the position of the bearing seat 4, and ensuring that the roll shaft 33 of the roll body 3 is accurately installed and limited.
[0041] Start the second motor 6 to drive the drive gear 61 to mesh with the driven gear 34, thereby rotating the upper roller 31 and the lower roller 32.
[0042] The steel billet is fed into the roll body 3 for rolling and forming, and the billet opening process is realized through continuous rolling.
[0043] After rolling is completed, the second motor 6 is stopped, and the bearing seat 4 is loosened through the installation unit 5 to facilitate the replacement or maintenance of the roll body 3.
[0044] Example 2: This example takes replacing the main body 3 of the roll as an example, combined with the attached... Figure 1 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows:
[0045] First, stop the equipment from running and ensure that the second motor 6 and the first motor 53 are de-energized.
[0046] The first motor 53 drives the bidirectional screw 54 to reverse, causing the adjusting block 52 to move to both sides, increasing the distance between the bearing seats 4, thereby loosening the roll shaft 33.
[0047] Remove the main body 3 of the roll from the movable frame 22.
[0048] When installing the new roll body 3, place the roll shaft 33 into the bearing housing 4 at the axis position.
[0049] Adjust the first motor 53 to move the adjusting block 52, clamp the bearing seat 4, and complete the replacement of the roll body 3.
[0050] Finally, the test drive assembly ensures that the drive gear 61 and driven gear 34 mesh well, and normal rolling can be resumed.
[0051] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
