Description

Technical Field

[0002] Reversible rolling mills, key equipment for cold-rolled thin strip, are widely used in steel plate production. Both hot rolling and cold rolling in steel plate production require annealing. However, in actual use, the annealing furnace takes too long to fully anneal the steel and cannot process multiple batches of material simultaneously. This results in the steel not being able to continue cold rolling due to the annealing furnace being occupied, causing the reversible rolling mill to be idle, affecting production scheduling efficiency, and leading to insufficient utilization of the rolling mill and annealing furnace, thus reducing production efficiency. Therefore, a reversible rolling mill with an integrated annealing furnace is needed to solve the above problems. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0021] according to Figures 1 to 5 As shown, a reversible rolling mill 2 with an integrated annealing furnace includes a base plate 1. The reversible rolling mill 2 and a double-cavity annealing furnace 3 are respectively arranged on the top of the base plate 1. A conveying assembly 4 and a guiding assembly 6 are respectively fixedly connected to the top of the base plate 1. The conveying assembly 4 is located at the discharge end of the reversible rolling mill 2. The other end of the conveying assembly 4 is connected to the guiding assembly 6. A driving assembly 5 is fixedly connected to the outside of the conveying assembly 4. The driving assembly 5 is used to control the operation of the conveying assembly 4. A first feeding assembly 8 is fixedly connected to the inside of the conveying assembly 4. The first feeding assembly 8 is used to push the material on the conveying assembly 4 onto the guiding assembly 6. The guiding assembly 6 can be flipped downwards to align the material with any one of the annealing cavities of the double-cavity annealing furnace 3. A second feeding assembly 7 is fixedly connected to the inside of the guiding assembly 6. The second feeding assembly 7 can be used to clamp the material and feed the material into any one of the annealing cavities of the double-cavity annealing furnace 3.

[0022] The reversible rolling mill 2 and the double-cavity annealing furnace 3 are respectively installed above the base plate 1. The two annealing cavities of the double-cavity annealing furnace 3 are distributed vertically. The conveying assembly 4 is used to receive the processed steel and convey the steel to the position corresponding to the guide assembly 6. The first feeding assembly 8 is used to push the steel on the conveying assembly 4 horizontally onto the guide assembly 6. When the guide assembly 6 is set horizontally, it corresponds to the upper annealing cavity in the double-cavity annealing furnace 3. At this time, the second feeding assembly 7 is used to clamp the steel and convey it into the upper annealing cavity for annealing. When the next batch of steel is processed and conveyed to the guide assembly 6, the guide assembly 6 is flipped downward so that the discharge end of the guide assembly 6 corresponds to the lower annealing cavity in the double-cavity annealing furnace 3. Then, the second feeding assembly 7 is used again to clamp the steel and convey it into the lower annealing cavity for annealing.

[0023] Preferably, the conveying assembly 4 includes an outer side plate 41 and an inner side plate 42. The bottom ends of the outer side plate 41 and the inner side plate 42 are fixedly connected to the bottom plate 1. A plurality of conveying rollers 43 are rotatably connected between the outer side plate 41 and the inner side plate 42. The plurality of conveying rollers 43 extend to the outside of the outer side plate 41 and are connected to the driving assembly 5. A plurality of rollers 44 are rotatably connected to the radial surface of the plurality of conveying rollers 43.

[0024] Multiple transmission rollers are rotatably connected between the outer side plate 41 and the inner side plate 42. Under the control of the drive assembly 5, the multiple transmission rollers rotate synchronously and in the same direction, so as to transport the steel from the discharge end of the reversible rolling mill 2 to the position corresponding to the guide assembly 6. The axial direction of the multiple rollers 44 rotatably connected to the radial surface of the multiple transmission rollers 43 is perpendicular to the axial direction of the transmission rollers. At this time, when the first feeding assembly 8 pushes the steel, the rollers 44 can reduce the friction between the steel and the transmission rollers 43, so as to facilitate the transverse pushing of the steel from the transmission assembly 4 to the guide assembly 6.

[0025] Preferably, the drive assembly 5 includes a first drive motor 54, which is fixedly connected to the outer surface of the outer side plate 41. The output end of the first drive motor 54 is coaxially fixedly connected to a drive shaft 53. Multiple fixing blocks are rotatably connected to the surface of the drive shaft 53, and the multiple fixing blocks are respectively fixedly connected to the outer surface of the outer side plate 41. Multiple driving bevel gears 52 are coaxially fixedly connected to the radial surface of the drive shaft 53. The driving bevel gears 52 respectively mesh with driven bevel gears 51, and the driven bevel gears 51 are respectively coaxially fixedly connected to one end of the corresponding conveyor roller 43.

[0026] The drive shaft 53 is mounted on the outer surface of the outer side plate 41 by multiple fixing blocks. One end of the drive shaft 53 is coaxially fixedly connected to the first drive motor 54. The first drive motor 54 can control the drive shaft 53 to rotate axially. When the drive shaft 53 rotates axially, it can synchronously drive the multiple active bevel gears 52 on its surface to rotate. Since the multiple active bevel gears 52 are respectively meshed with driven bevel gears 51, the active bevel gears 52 can also synchronously drive the corresponding driven bevel gears 51 to rotate when they rotate. The rotation of the driven bevel gears 51 can synchronously drive the corresponding conveyor rollers 43 to rotate axially, thereby realizing the conveying of steel.

[0027] Preferably, the first feeding assembly 8 includes a third electric push rod 82, the fixed end of the third electric push rod 82 is fixedly connected to the inner side of the outer side plate 41, the telescopic end of the third electric push rod 82 is fixedly connected to the feeding plate 81, and the two sides of the third electric push rod 82 are symmetrically provided with second telescopic rods 83, and the two ends of the second telescopic rods 83 are fixedly connected to the feeding plate 81 and the outer side plate 41 respectively.

[0028] After the steel is moved to the position corresponding to the guide assembly 6 by multiple conveying rollers 43, the extension of the third electric push rod 82 causes the outer surface of the feeding plate 81 to contact the surface of one side of the steel. Since the telescopic end of the third electric push rod 82 continues to extend, the rollers 44 on the surface of the feeding plate 81 and the conveying rollers 43 push the material from above the conveying rollers 43 into the guide assembly 6, realizing the operation of moving the steel from the conveying assembly 4 to the guide assembly 6. The second telescopic rod 83 can effectively increase the stability and balance of the movement of the feeding plate 81.

[0029] Preferably, the guide assembly 6 includes a front side plate 61 and a rear side plate 62, which are fixedly connected to the base plate 1. An arc-shaped groove 63 is provided at one right end of each of the front and rear side plates 61 and 62. A flip plate 64 is rotatably connected to the inner side of each of the front and rear side plates 61 and 62. Multiple rotating rollers 65 are rotatably connected to the inner side of each flip plate 64. A rotating shaft 67 is fixedly connected to one left end of each flip plate 64. The flip plate 64 is connected to the front side plate 61 via the rotating shaft 67. The front side plate 61 and the rear side plate 62 are rotatably connected to each other. The right side of the flip plate 64 is fixedly connected to a sliding shaft 68, which is slidably connected to the corresponding arc-shaped sliding groove 63. The outer surfaces of the front side plate 61 and the rear side plate 62 are connected to a first electric push rod 66. The fixed end of the first electric push rod 66 is hinged to the front side plate 61 and the rear side plate 62. The telescopic end of the first electric push rod 66 is respectively hinged to the corresponding sliding shaft 68. The second feeding assembly 7 is fixedly connected to the inner side of the corresponding flip plate 64.

[0030] After the steel is pushed to the center position above the multiple rotating rollers 65 by the feeding plate 81, the second feeding assembly 7 can clamp and fix the steel. At the same time, in the initial state, the first electric push rod 66 extends, and the sliding shaft 68 is located at the top of the arc-shaped sliding groove 63. Therefore, the sliding shaft 68 and the rotating shaft 67 cooperate to make the tilting plate 64 horizontally set. At the same time, the second feeding assembly 7 can feed the steel into the upper annealing chamber of the double-cavity annealing furnace 3 for annealing. When the next batch of steel needs to be annealed, the extension of the first electric push rod 66 is controlled. When the retracted end is retracted, the sliding shaft 68 slides to the bottom of the arc-shaped chute 63. Through the cooperation of the sliding shaft 68 and the rotating shaft 67, the tilting plate 64 tilts downward with the rotating shaft 67 as the axis. After tilting downward, the right end of the tilting plate 64 corresponds to the lower annealing chamber of the double-chamber annealing furnace 3. Then, the steel is fed into the lower annealing chamber for annealing using the second feeding assembly 7. This operation effectively improves the utilization rate of the annealing furnace and avoids the problem that the reversible rolling mill 2 needs to be stopped and waited because there is steel that needs to be annealed in the annealing furnace.

[0031] Preferably, the second feeding assembly 7 includes a linear chute 71, which is respectively opened inside the corresponding flip plate 64. A movable block 72 is slidably connected inside the linear chute 71. A threaded hole is opened on the left side of the movable block 72, and a threaded rod 73 is threadedly connected inside the threaded hole. One end of the threaded rod 73 is rotatably connected to the left side wall of the linear chute 71. At the same time, one end of the threaded rod 73 extends to the outside of the flip plate 64 and is coaxially fixedly connected to a driven spur gear 76. The top of the driven spur gear 76 meshes with a driving spur gear 75. A second drive motor 74 is fixedly connected to the top of the flip plate 64. The output end of the second drive motor 74 is coaxially fixedly connected to the corresponding driving spur gear 75. A clamping assembly is fixedly connected inside the movable block 72. The clamping assembly is used to contact and clamp the material on both sides.

[0032] First, the steel is clamped and fixed by the inward contraction of the clamping assembly inside the moving block 72. Then, the second drive motor 74 above the flip plate 64 drives the active spur gear 75 to rotate synchronously. The rotating active spur gear 75 drives the driven spur gear 76 to rotate. The rotating driven spur gear 76 drives the threaded rod 73 located in the linear slide 71 to rotate. Since the threaded rod 73 and the moving block 72 are connected by a threaded hole, the moving block 72 can move from the linear slide 71 toward the double-cavity annealing furnace 3 when the threaded rod 73 rotates. The movement of the moving block 72 can drive the steel to move into any annealing cavity of the double-cavity annealing furnace 3 through the clamping assembly, thereby facilitating the annealing operation of the steel.

[0033] Preferably, the clamping assembly includes a clamping plate 78, and a second electric push rod 77 and two first telescopic rods 79 are fixedly connected between the clamping plate 78 and the moving block 72. The fixed end of the second electric push rod 77 is fixedly connected to the moving block 72, and the telescopic end of the second electric push rod 77 is fixedly connected to the clamping plate 78. The two first telescopic rods 79 are symmetrically arranged on both sides of the second electric push rod 77, and the two ends of the two first telescopic rods 79 are fixedly connected to the clamping plate 78 and the moving block 72, respectively.

[0034] When the two first electric push rods 66 extend inward, they can drive the clamping plate 78 at the telescopic end to retract synchronously. After the inner side of the synchronously retracted clamping plate 78 contacts the front and rear surfaces of the steel, it can clamp and fix the steel. Then, when the moving block 72 moves to the right, it can drive the steel to move to the right synchronously, thereby realizing the operation of sending the steel into the annealing chamber. The two second telescopic rods 83 can increase the stability of the movement of the clamping plate 78.

[0035] Preferably, the two annealing chambers of the dual-chamber annealing furnace 3 are distributed vertically, and a guide roller is fixedly connected to the front end of the lower annealing chamber.

[0036] A guide roller is provided at the front end of the annealing chamber located below. The guide roller can contact the steel and conveniently assist the second feeding assembly 7 in feeding the steel into the annealing chamber below for annealing.

[0037] Preferably, a slant plate is fixedly connected to one end of the left side of the clamping plate 78.

[0038] The inclined plate tilts outward, which allows the steel to enter better between the two clamping plates 78, improving the stability of steel conveying.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
