Technical Field

[0001] The utility model relates to the field of metal processing, in particular to a material guiding device for a strip inlet of a rolling mill. Background Art

[0002] As one of the important equipment in the field of metal processing, the roller mill can press metal materials and change their cross-sectional shape and size to meet the needs of different customers.

[0003] In actual production, when conveying the strip to the rolling mill, the motor in the rolling mill will generate vibrations when rotating at high speed. These vibrations will be transmitted to other parts of the rolling mill, including the strip, causing the strip to shake when feeding and unable to maintain stability when entering the feed port of the rolling mill. Manual real-time adjustments are required, which is time-consuming and labor-intensive, and there is room for improvement. Utility Model Content

[0004] In order to solve the problem of strip conveying shaking in the background technology, the present application provides a strip inlet guiding device for a rolling mill.

[0005] The present application provides a rolling mill strip inlet guide device, which adopts the following technical solution:

[0007] By adopting the above technical solution, the slide and guide wheels on the base are used to guide the strip, and the position of the slide is adjusted by the adjustment mechanism to adapt to strips of different widths, thereby improving the adaptability and stability of the material guiding device. The design of the adjustment mechanism makes it more convenient to adjust the position of the slide, further improving the ease of use of the material guiding device.

[0008] Preferably, the adjusting mechanism comprises a threaded rod and a handwheel for driving the threaded rod to rotate, the threaded rod is rotatably connected to the base, and the slide is provided with a thread that matches the threaded rod.

[0009] By adopting the above technical solution, the hand wheel is rotated to drive the threaded rod to rotate, thereby driving the slide to move, thereby achieving precise adjustment of the slide position.

[0010] Preferably, the guide wheel is detachably and rotatably connected to the slide.

[0011] By adopting the above technical solution, the guide wheel is detachably rotatably connected to the slide, which facilitates the replacement and maintenance of the guide wheel and reduces the friction with the strip, thereby increasing the service life of the material guiding device.

[0012] Preferably, the guide wheel is a concave wheel with a depression in the middle.

[0013] By adopting the above technical solution, the middle depression of the guide wheel guides the strip, and the design of the concave wheel can better fix and guide the strip, prevent the strip from deflecting or shaking during the feeding process, and improve the stability of the material guiding.

[0014] Preferably, the two threaded rods are integrally formed, and the threads of the two threaded rods have opposite rotation directions.

[0015] By adopting the above technical solution, the two threaded rods are integrated into one threaded rod, and the threads of the two threaded rods have opposite rotation directions, so that when a handle is turned, the relatively arranged slides can slide towards or away from each other at the same time, which increases the convenience of operation.

[0017] By adopting the above technical solution, a connecting piece is detachably arranged between the two threaded rods. The thread rotation directions of the two threaded rods are different, so they can act as bidirectional screw rods when needed. When one handle is turned, the relatively arranged slides can slide towards or away from each other at the same time; at the same time, when it is necessary to adjust the slide on one side, the connecting piece can be removed to adjust the slide on one side.

[0018] Preferably, a liquid storage tank is also provided on the base.

[0019] By adopting the above technical solution, the liquid storage tank can be used to store liquids such as lubricating oil, which is convenient for lubrication and maintenance of the material guiding device.

[0020] Preferably, the slide is provided with a tightening bolt which is tightly fitted with the base.

[0021] By adopting the above technical solution, when the slide is adjusted to a suitable position, the slide is tightened with a tightening bolt to prevent the slide from loosening during the feeding process, thereby increasing safety during use.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The adaptability and stability of the material guide device are improved by setting the base, slide, guide wheel and adjustment mechanism, solving the problem that the existing material guide device is difficult to stably fix the strip under the drive of a high-speed rotating motor;

[0024] 2. The detachable connection of the guide wheel, the concave wheel design and the setting of the tightening bolts can better fix and guide the strip, prevent the strip from deflecting, shaking or falling off during the feeding process, thereby improving the rolling stability and rolling quality.

[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0030] Embodiment 1

[0031] The embodiment of the present application discloses a material guiding device for a strip inlet of a rolling mill.

[0032] Reference Figure 1 A rolling mill strip inlet material guiding device comprises a base 1, a slide 2 is arranged above the base 1, two slides 2 are symmetrically arranged along the length direction of the strip, that is, the two slides 2 are respectively located on both sides of the strip, two guide wheels 21 are arranged on any slide 2, and the two guide wheels 21 on any slide 2 form abutment and sliding fit with one side of the strip width direction to ensure that the strip can move stably on the slide 2; an adjusting mechanism 3 for adjusting the movement of the slide 2 along the strip width direction is arranged on the base 1 corresponding to the number of slides 2, and the adjusting mechanism 3 is accurately matched with the required strip width to ensure that the strip can stably enter the rolling mill.

[0033] Since the structures and connection methods of the two adjustment mechanisms 3 are the same, the structure and connection method of one of the adjustment mechanisms 3 is taken as an example for explanation.

[0034] Reference Figure 1The adjusting mechanism 3 includes a threaded rod 31 and a handwheel 32 for driving the threaded rod 31 to rotate. In the embodiment of the present application, one slide 2 is correspondingly provided with a threaded rod 31 and a handwheel 32. The threaded rod 31 is rotatably connected to the base 1. The length direction of the threaded rod 31 is horizontally arranged and perpendicular to the length direction of the strip. A thread matching the threaded rod 31 is arranged at the bottom of the slide 2. In actual use, the slide 2 is driven to a suitable position by rotating the relatively arranged handwheel 32 to achieve the clamping of the strip and ensure the stable feeding of the rolling mill.

[0035] Reference Figure 1 The guide wheel 21 is detachably rotatably connected to the slide 2, and a cover plate 22 is detachably connected to the slide 2 by bolts. An installation space is formed between the cover plate 22 and the slide 2, and the guide wheel 21 is located in the installation space, and the rotation axis of the guide wheel 21 is perpendicular to the rotation axis of the threaded rod 31 and is vertically arranged; wherein, a rotating bearing is interference-fitted in the guide wheel 21, and a connecting shaft is integrally formed with the inner ring of the rotating bearing, and both ends of the connecting shaft are respectively embedded with the cover plate 22 and the slide 2. In the embodiment of the present application, the two guide wheels 21 on any slide 2 are installed in the installation space between the cover plate 22 and the slide 2 in the same manner.

[0036] During actual replacement, it is only necessary to remove the bolts of the cover plate 22, and then take off the cover plate 22, and then the guide wheel 21 and the rotating bearing can be directly removed together, so as to realize the detachable replacement of the guide wheel 21, thereby extending the service life of the material guiding device; the guide wheel 21 is a concave wheel with a depression in the middle, which can better fix and guide the strip and prevent the strip from deflecting or shaking during the feeding process.

[0037] Reference Figure 1 A liquid reservoir 11 is also provided on the base 1. The liquid reservoir 11 is located below the slide 2 and can be used to store coolant or lubricant to directly lubricate the threaded rod 31, thereby improving the service life and stability of the equipment.

[0038] Reference Figure 1 The base 1 is provided with a locking bolt 23 which is tightly fitted with the slide 2. When the slide 2 moves to a predetermined position, it can be locked on the base 1 by the locking bolt 23 to prevent the slide 2 from moving due to accidental touch or other external forces. This design can significantly improve the stability and safety of the material guiding device, and avoid affecting the material guiding effect or causing safety accidents due to changes in the position of the slide 2.

[0039] The implementation principle of the embodiment of the present application is: when in use, first place the strip between the relatively arranged guide wheels 21, and then turn the hand wheel 32 to drive the threaded rod 31 to rotate, drive the slide 2 to move, and make the guide wheel 21 clamp the strip; because the guide wheel 21 adopts a concave design, it can fit closely to the surface of the strip to prevent it from shifting or shaking during the rolling process; in this way, the stability problem of the strip at the feed port of the rolling mill can be effectively solved, and the rolling quality and efficiency can be improved.

[0040] Embodiment 2

[0041] The embodiment of the present application also discloses a multi-layer stacking device for an annealing furnace.

[0042] The difference between the embodiment of the present application and the first embodiment is that the threads of the two threaded rods 31 on the adjusting mechanism 3 arranged opposite to each other have opposite directions of rotation, and a connecting piece 4 is detachably provided in the middle of the threaded rod 31 .

[0043] Reference Figure 2 The connecting piece 4 in the embodiment of the present application is a coupling sleeve, and the ends of the two threaded rods 31 close to each other are each provided with a key groove that matches the coupling sleeve. The coupling sleeve is provided with a connecting key that realizes an interference fit with the key grooves of the two threaded rods 31, that is, the two ends of the coupling sleeve are key-connected with the relatively arranged threaded rods 31, and the two ends of the coupling sleeve are connected to the two threaded rods 31 to transmit torque; the setting of the connecting piece 4 enables the two threaded rods 31 to rotate synchronously.

[0044] In actual situations, two relatively arranged slides 2 can be moved closer to or farther away from each other by turning only one hand wheel 32, which can further increase the stability of the entire device and prevent the device from shaking or deflecting due to vibration or impact during the rolling process.

[0045] Reference Figure 3 In the embodiment of the present application, the coupling sleeve is a detachable connection, wherein the length of the keyways on the two threaded rods 31 is set to be greater than or equal to the length of the connecting key in the coupling sleeve. When it is necessary to disconnect the synchronous rotation connection of the relatively arranged threaded rods 31, it is only necessary to slide the coupling sleeve along the length direction of the threaded rods 31 so that the connecting key on the coupling sleeve is completely matched with the keyway on one of the threaded rods 31. At this time, the coupling sleeve will disengage the key connection of the other threaded rod 31, realizing the disconnection of the key connection, so that the synchronous rotation of the relatively arranged threaded rods 31 can be disconnected. The detachable connection method of the connecting piece 4 is convenient for removing it when it is not needed to meet the needs of different usage scenarios.

[0046] The implementation principle of the embodiment of the present application is:

[0047] When the two ends of the coupling sleeve are connected to the two threaded rods 31, when a hand wheel 32 is turned, the relatively arranged slides 2 can be moved simultaneously through the connecting piece 4 on the threaded rod 31 and the threads with opposite rotation directions on the relatively arranged threaded rod 31, so that the relatively arranged slides 2 can be moved closer to or farther away from each other, which makes it more convenient to adjust the slides 2 and improves the operating efficiency. When the relatively arranged threaded rods 31 do not need to rotate synchronously, the coupling sleeve can be pushed along the length direction of the threaded rod 31 to disconnect its key connection, so that the synchronous rotation of the relatively arranged threaded rods 31 can be disconnected to meet the usage requirements under different conditions.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
