Description

Technical Field

[0001] This utility model relates to the field of iron and steel metallurgy technology, and in particular to a rolling mill gap adjustment mechanism. Background Technology

[0002] A rolling mill is a piece of equipment used in the metal rolling process. Roll bearings, as key components of the mill, support the rolls and maintain their fixed position within the mill stand. Roll bearings bear heavy and variable loads, thus requiring low friction coefficients, sufficient strength and rigidity, and ease of roll replacement. During mill operation, the smaller the gap between the sliding plates on both sides of the support roll bearing housing and the mill stand liners, the higher the mill's precision.

[0003] In existing rolling mill gap adjustment mechanisms, the gap between two rolls needs to be adjusted during the rolling process to facilitate the rolling of metals of different thicknesses. However, when adjusting the gap between the two rolls, it is not convenient for the two ends of the rolls to be raised and lowered synchronously, resulting in the rolls not being level after adjustment. This affects the accuracy of the rolls rolling the metal. Moreover, after adjusting the gap between the upper and lower rolls, it is not convenient to adjust the drive rotation structure between the two rolls, affecting the rotation of the two rolls and the rolling of the metal.

[0004] Therefore, a rolling mill gap adjustment mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when adjusting the gap between two rolls, the two ends of the rolls are not easy to adjust synchronously, resulting in the rolls not being level after adjustment, which affects the accurate rolling of metal by the rolls. Therefore, a gap adjustment mechanism for rolling mills is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a rolling mill gap adjustment mechanism, including a base, a mounting frame fixed to the top of the base, two rollers with a gap between them at the bottom of the mounting frame, a support column passing through the middle of the rollers, a sliding plate connected to the surface of the support column at both ends of the rollers, bearing seats for rotatable mounting between the support column and the mounting frame are slidably mounted at both ends of the support column outside the sliding plate, one end of the two rollers is equipped with a drive rotation mechanism at the outside of the mounting frame, a lifting adjustment mechanism is mounted on the top of the upper roller, and a locking positioning mechanism is provided between the side of the lifting adjustment mechanism and the top side of the mounting frame. The lifting and adjusting mechanism includes a sliding groove formed inside the mounting frame, a sliding block installed on the outside of the bearing seat and slidably installed inside the sliding groove, a lifting frame fixedly connected to the tops of the two sliding blocks and slidingly passing through the top of the mounting frame, a support frame fixedly installed in the middle of the top of the mounting frame, and a drive rod for driving the lifting frame to move up and down by rotating through the middle of the support frame and rotating through the middle of the top of the lifting frame.

[0007] Furthermore, the mounting frame has a U-shaped structure and is vertically arranged. One end of the support column rotatably extends out of one side of the mounting frame. Both rollers are horizontally arranged. The lower roller is rotatably mounted between the bearing seat and the support column and the fixed positions on both sides of the inside of the mounting frame, and is close to the base. The upper roller is rotatably mounted between the bearing seat, the support column and the sliding block and the two sides of the inside of the mounting frame, and is mounted in a way that can be adjusted up and down by means of the sliding groove.

[0008] Furthermore, a lifting groove is formed at the top of the sliding groove and at both ends of the top of the mounting frame. The lifting groove is vertically arranged, and the lifting frame has a U-shaped structure that slides vertically through the lifting groove, with its top end spanning the top of the mounting frame.

[0009] Furthermore, the top center of the lifting frame has a drive hole, which is a threaded hole structure. The support frame is a U-shaped structure and is vertically installed on both sides of the lifting frame. The drive rod is a threaded rod structure and rotates vertically through the drive hole. The top of the drive rod is equipped with a first motor that is fixedly installed on the top of the support frame.

[0010] Furthermore, the snap-fit ​​positioning mechanism includes snap-fit ​​teeth evenly fixed to the outside of the lifting frame, snap-fit ​​tooth plates meshing with the outside of the snap-fit ​​teeth, a connecting plate fixedly connected to the outside of the snap-fit ​​tooth plates, and tension springs connected to the inner sides of both ends of the connecting plate for pulling the snap-fit ​​tooth plates to move.

[0011] Furthermore, a snap-fit ​​hole is provided on the top side of the mounting bracket and at the top side of the lifting groove. The snap-fit ​​toothed plate slides horizontally through the snap-fit ​​hole and engages with the snap-fit ​​teeth inside the lifting groove. The tension spring is installed on both sides of the snap-fit ​​toothed plate, and its inner end is connected to the outer side of the mounting bracket.

[0012] Furthermore, the drive rotation mechanism includes a first gear fixed to the protruding end surface of the support column, a second gear meshing with one side of the first gear, a mounting plate slidably mounted on the outside of the mounting frame for rotatably mounting the two second gears, a side plate fixedly mounted on the side of the mounting frame and located outside the mounting plate, a mounting rod fixed to both ends of the side of the mounting plate and slidably passing through the side plate, and an electric push rod fixedly mounted in the middle of the outer side of the side plate and whose telescopic end is fixedly connected to the middle of the side of the mounting plate for moving and adjusting the position of the mounting plate and the second gear.

[0013] Furthermore, the two second gears are located on one side between the two first gears and are distributed in a V-shape. A connecting frame is fixed to the bottom end of the mounting plate. The connecting frame has a C-shaped structure and is spaced apart on the outside of one of the lower second gears. A second motor is fixedly installed at the top of the outside of the connecting frame. The output end of the second motor is fixedly connected to the central shaft of one of the lower second gears and drives it to rotate.

[0014] Furthermore, both the mounting rod and the electric push rod are horizontally arranged, while the side plate is vertically arranged with mounting holes at its upper and lower ends. The mounting rod slides through the mounting holes, and nuts for stabilizing the second gear are connected to the surface of the mounting rod at positions on both sides of the mounting holes.

[0015] Compared with the prior art, the advantages of the rolling mill gap adjustment mechanism proposed in this utility model are as follows: 1. This utility model installs sliding blocks at both ends of an upper roller, allowing the upper roller to move up and down along the sliding groove inside the mounting frame. Therefore, the first motor drives the drive rod to rotate, and drives the lifting frame to move up and down along the lifting groove through the drive hole. This, in turn, drives the roller and support column to move up and down through both ends of the lifting frame, thereby adjusting the gap between the two rollers. This facilitates accurate and horizontal adjustment of the roller position, and thus facilitates accurate rolling of metal.

[0016] 2. In this invention, when adjusting the position of the roller horizontally via the lifting frame, the connecting plate pulls the locking tooth plate outward, facilitating the movement of the lifting frame along the lifting groove. After adjusting the roller gap size, the drive rod is stopped, and the connecting plate is released. The tension spring pulls the locking tooth plate inward along the locking hole, causing the locking tooth plate to engage with the locking tooth side of the lifting frame. This ensures the lifting frame is stably mounted on the mounting frame, thereby maintaining the stable setting of the adjusted roller and ensuring the accuracy of the gap.

[0017] 3. After adjusting the gap between the two rolls, the distance between the two first gears changes. Loosening the nut causes the electric push rod to move the mounting plate along the mounting rod, bringing the two second gears closer to the two first gears. This allows the upper second gear to mesh with the upper first gear, and the lower second gear to mesh with the lower first gear. Therefore, during the rolling process, the metal enters the gap, and the second motor drives one second gear to rotate, meshing with and driving the other second gear to rotate. This allows the two first gears to mesh and rotate synchronously in opposite directions, thus rolling and pushing the metal inside the gap, facilitating rapid rolling and removal of the metal from the gap.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] For examples, please refer to Figures 1 to 6 The diagram shows a rolling mill gap adjustment mechanism, including a base 1. A mounting frame 3 is fixed to the top of the base 1. There are two rollers 2 with a gap between them at the bottom of the mounting frame 3. A support column 15 passes through the middle of the rollers 2. A sliding plate 22 is connected to the surface of the support column 15 at both ends of the rollers 2. Bearing seats 23 for rotating between the support column 15 and the mounting frame 3 are sleeved at both ends of the support column 15 at positions slidably disposed outside the sliding plate 22. A drive rotation mechanism is installed at one end of the two rollers 2 at a position outside the mounting frame 3. A lifting adjustment mechanism is installed at the top of the upper roller 2. A locking positioning mechanism is provided between the side of the lifting adjustment mechanism and the top side of the mounting frame 3.

[0022] The mounting frame 3 has a U-shaped structure and is vertically installed. One end of the support column 15 rotates out through one side of the mounting frame 3. Both rollers 2 are horizontally installed. The lower roller 2 is rotatably installed between the bearing seat 23 and the support column 15 and the fixed positions on both sides inside the mounting frame 3, and is close to the base 1. The upper roller 2 is rotatably installed between the bearing seat 23, the support column 15 and the sliding block 4 and the two sides inside the mounting frame 3, and is installed in a way that can be adjusted up and down by sliding through the sliding groove 5.

[0023] In detail, the lifting and adjusting mechanism includes a sliding groove 5 opened inside the mounting frame 3, a sliding block 4 installed on the outside of the bearing seat 23 and slidably installed inside the sliding groove 5, a lifting frame 6 fixedly connected to the top of the two sliding blocks 4 and sliding through the top of the mounting frame 3, a support frame 7 fixedly installed in the middle of the top of the mounting frame 3, and a drive rod 9 for driving the lifting frame 6 to move up and down by rotating through the middle of the support frame 7 and rotating through the middle of the top of the lifting frame 6.

[0024] A lifting groove 26 is provided at the top of the sliding groove 5 and at both ends of the top of the mounting frame 3. The lifting groove 26 is set vertically. The lifting frame 6 has a U-shaped structure and slides vertically through the lifting groove 26, with its top end spanning the top of the mounting frame 3.

[0025] The top center of the lifting frame 6 has a drive hole 21, which is a threaded hole structure. The support frame 7 is a U-shaped structure and is vertically installed on both sides of the lifting frame 6. The drive rod 9 is a threaded rod structure and rotates vertically through the drive hole 21. The top of the drive rod 9 is equipped with a first motor 8 that is fixedly installed on the top of the support frame 7.

[0026] The first motor 8 drives the drive rod 9 to rotate, and drives the lifting frame 6 to move up and down along the lifting groove 26 through the drive hole 21. Thus, the two ends of the lifting frame 6 drive the roller 2 and the support column 15 to move up and down, thereby adjusting the gap between the two rollers 2. This facilitates accurate and horizontal adjustment of the position of the roller 2 and the size of the gap, and thus facilitates accurate rolling of the metal.

[0027] Furthermore, the snap-fit ​​positioning mechanism includes snap-fit ​​teeth 10 evenly fixed to the outside of the lifting frame 6, snap-fit ​​tooth plates 11 engaging and snapping with the outside of the snap-fit ​​teeth 10, connecting plates 12 fixedly connected to the outside of the snap-fit ​​tooth plates 11, and tension springs 13 connected to the inner sides of both ends of the connecting plates 12 for pulling the snap-fit ​​tooth plates 11 to move.

[0028] A snap-fit ​​hole 25 is provided on the top side of the mounting bracket 3, which is located at the top side of the lifting groove 26. The snap-fit ​​tooth plate 11 slides horizontally through the snap-fit ​​hole 25 and engages with the snap-fit ​​teeth 10 inside the lifting groove 26. The tension spring 13 is installed on both sides of the snap-fit ​​tooth plate 11, and its inner end is connected to the outer side of the mounting bracket 3.

[0029] When the lifting frame 6 adjusts the position of the roller 2 horizontally, the connecting plate 12 pulls the locking tooth plate 11 outward to facilitate the movement of the lifting frame 6 along the lifting groove 26. After adjusting the gap size between the two rollers 2, the drive rod 9 is stopped from rotating. At the same time, the connecting plate 12 is released, and the tension spring 13 pulls the locking tooth plate 11 inward along the locking hole 25, so that the locking tooth plate 11 engages with the side of the locking tooth 10 on the side of the lifting frame 6, thereby keeping the lifting frame 6 stably locked on the mounting frame 3, thus keeping the adjusted roller 2 stably set and keeping the gap accurate.

[0030] Finally, the drive rotation mechanism includes a first gear 14 fixed to the protruding end surface of the support column 15, a second gear 16 meshing with one side of the first gear 14, a mounting plate 28 slidably mounted on the outside of the mounting frame 3 for rotatably mounting the two second gears 16, a side plate 24 fixedly mounted on the side of the mounting frame 3 and located outside the mounting plate 28, a mounting rod 19 fixed to both ends of the side of the mounting plate 28 and sliding through the side plate 24, and an electric push rod 20 fixedly mounted in the middle of the outside of the side plate 24 and whose telescopic end is fixedly connected to the middle of the side of the mounting plate 28 for moving and adjusting the position of the mounting plate 28 and the second gear 16.

[0031] Two second gears 16 are located on one side between two first gears 14 and are distributed in a V-shape. A connecting frame 18 is fixed to the bottom end of the mounting plate 28. The connecting frame 18 has a C-shaped structure and is spaced apart on the outside of one of the lower second gears 16. A second motor 17 is fixedly installed on the top of the outside of the connecting frame 18. The output end of the second motor 17 is fixedly connected to the central shaft of one of the lower second gears 16 and drives it to rotate.

[0032] The electric push rod 20 drives the mounting plate 28 to extend and retract along the mounting rod 19, so that the mounting plate 28 drives the two second gears 16 to approach the two first gears 14, thereby making the upper second gear 16 mesh with the upper first gear 14, and the lower second gear 16 mesh with the lower first gear 14.

[0033] Both the mounting rod 19 and the electric push rod 20 are horizontally arranged, while the side plate 24 is vertically arranged. Mounting holes 27 are opened at the upper and lower ends of its surface. The mounting rod 19 slides through the mounting holes 27. Nuts 29 for stabilizing the second gear 16 are connected to the surface of the mounting rod 19 and at the positions on both sides of the mounting holes 27.

[0034] During the rolling process of the rolling mill through the rolls 2, the metal enters the gap. At the same time, the second motor 17 drives one second gear 16 to rotate and meshes with another second gear 16 to rotate, so that the two first gears 14 can be synchronously meshed and driven to rotate. The two first gears 14 rotate in opposite directions, thereby rolling and pushing the metal inside the gap, which facilitates the rapid rolling and removal of the metal from the gap.

[0035] Working method: By installing sliding blocks 4 at both ends of the upper roller 2, the upper roller 2 can move up and down along the sliding groove 5 inside the mounting frame 3. Therefore, the first motor 8 drives the drive rod 9 to rotate, and drives the lifting frame 6 to move up and down along the lifting groove 26 through the drive hole 21. Thus, the roller 2 and the support column 15 are moved up and down through the two ends of the lifting frame 6, thereby adjusting the gap between the two rollers 2. This facilitates accurate and horizontal adjustment of the position of the roller 2 and the size of the gap, thus facilitating accurate rolling of metal.

[0036] When the lifting frame 6 adjusts the position of the roller 2 horizontally, the connecting plate 12 pulls the locking tooth plate 11 outward to facilitate the movement of the lifting frame 6 along the lifting groove 26. After adjusting the gap size between the two rollers 2, the drive rod 9 is stopped from rotating. At the same time, the connecting plate 12 is released, and the tension spring 13 pulls the locking tooth plate 11 inward along the locking hole 25, so that the locking tooth plate 11 engages with the side of the locking tooth 10 on the side of the lifting frame 6, thereby keeping the lifting frame 6 stably locked on the mounting frame 3, thus keeping the adjusted roller 2 stably set and keeping the gap accurate.

[0037] After adjusting the gap between the two rolls 2, the distance between the two first gears 14 changes. Loosen the nut 29, and the electric push rod 20 drives the mounting plate 28 to move along the mounting rod 19. This causes the mounting plate 28 to move the two second gears 16 closer to the two first gears 14, so that the upper second gear 16 meshes with the upper first gear 14, and the lower second gear 16 meshes with the lower first gear 14.

[0038] Therefore, during the rolling process of the rolling mill through the rolls 2, the metal enters the gap. At the same time, the second motor 17 drives one second gear 16 to rotate and meshes with another second gear 16 to rotate, so that the two first gears 14 can be synchronously meshed and driven to rotate. The two first gears 14 rotate in opposite directions, thereby rolling and pushing the metal inside the gap, which facilitates the rapid rolling and removal of the metal from the gap.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
