Description

Technical Field

[0001] This utility model relates to the field of steel plate pressing and straightening technology, and in particular to steel plate production pressing and straightening equipment. Background Technology

[0002] Steel plate straightening is a key process in steel plate production. It involves plastically deforming the steel plate through mechanical processing methods such as rolling and straightening to precisely control its thickness, flatness, surface quality, and internal stress distribution. This process can eliminate defects such as uneven thickness, wavy bends, and warping generated during the rolling process, ensuring that its dimensional accuracy meets micron-level tolerance requirements. At the same time, it optimizes the mechanical properties and microstructure of the material, improving the strength, toughness, or electromagnetic properties of the steel plate. Steel plate straightening not only directly affects the final quality of the product but also reduces the scrap rate in subsequent processing and lowers production costs. It is a core technology link to meet the high-end needs of the automotive, aerospace, and new energy battery industries.

[0003] Traditional steel plate production pressing equipment lacks an automatic turning mechanism. The steel plate is repeatedly subjected to pressure on one side, which can lead to surface hardening or localized wear. Especially during high-speed rolling, impurities may be pressed into the surface of the steel plate, forming permanent scratches or pits, affecting the appearance of the product or the quality of subsequent coatings. Symmetrical rolling processes cannot be achieved. The lack of a turning mechanism limits the development of product types, reduces the practicality of the equipment, and weakens the market competitiveness of the products.

[0004] Therefore, in response to the problem that the traditional steel plate production pressing equipment lacks an automatic flipping mechanism, which affects the appearance of the product or the quality of subsequent coatings, makes it impossible to achieve symmetrical rolling process, and weakens the market competitiveness of the product, a steel plate production pressing equipment with an automatic flipping mechanism can be designed. Utility Model Content

[0005] In order to overcome the problem that traditional steel plate production pressing equipment lacks an automatic turning mechanism, which affects the appearance of the product or the quality of subsequent coatings, and cannot achieve symmetrical rolling process, thus weakening the product's market competitiveness.

[0006] The technical solution of this utility model is as follows: a steel plate production pressing and straightening equipment, including a support frame; it also includes a conveying component and a receiving support. Two conveying components are provided at both ends of the support frame, and a flip plate is provided between the two conveying components. Two connecting shafts are fixedly connected to both ends of the flip plate. Two gears are fixedly connected to both ends of one connecting shaft. Two sets of receiving supports are fixedly connected above the support frame. One set of receiving supports is movably connected to a connecting shaft without gears, and the other set of receiving supports is rotatably connected to another connecting shaft. A rack is meshed below the gears and is slidably connected to a sliding track. A connecting column is fixedly connected below the rack, and a limit plate is fixedly connected to the connecting column. A hydraulic rod is fixedly connected to the limit plate, and the other end of the hydraulic rod is fixedly connected to the output end of a hydraulic cylinder. The hydraulic cylinder is fixedly connected to the support frame.

[0007] Preferably, the steel plate is placed on the conveying assembly, and after single-sided rolling, it is conveyed to the top of the flipping plate. Then, the hydraulic cylinder outputs pressure to the hydraulic rod, pushing the hydraulic rod to move. The hydraulic rod drives the limiting plate to move. The limiting plate drives the rack to slide on the sliding track through the connecting column. The rack drives the gear meshing above to rotate. The gear drives the connecting shaft to rotate, thereby realizing the connecting shaft driving the flipping plate to rotate, completing the flipping of the steel plate, and conveying the other side of the steel plate to the conveying assembly for rolling.

[0008] Preferably, the flip plate is equipped with several negative pressure suction cups, and a load-bearing platform is provided below the flip plate, which is fixedly connected to the support frame.

[0009] Preferably, a through-hole groove is provided below the sliding track, and a connecting column is slidably connected to the through-hole groove.

[0010] Preferably, the conveying assembly includes a first motor, a lower rotating shaft, a first belt, and a lower pressure roller. The first motor is fixedly connected to the support frame, and the output end of the first motor is fixedly connected to the lower rotating shaft. The lower rotating shaft is rotatably connected to the support frame, and the first belt is sleeved on the outside of the lower rotating shaft. The lower pressure roller is fixedly connected to the lower rotating shaft.

[0011] Preferably, several distance sensors are fixedly connected to the support frame, and two gantry frames are fixedly connected to both sides of the support frame. The distance sensors are electrically connected to a second motor.

[0012] Preferably, two second motors are fixedly connected to the upper two ends of the gantry frame. The output end of the second motor is fixedly connected to a threaded rod, which is rotatably connected to the gantry frame. A sliding frame is threadedly connected to the threaded rod.

[0013] Preferably, a third motor is fixedly connected to the sliding frame, and an upper rotating shaft is fixedly connected to the output end of the third motor. The upper rotating shaft is rotatably connected to the sliding frame, and a second belt is sleeved on the outside of the upper rotating shaft. An upper pressure roller is fixedly connected to the upper rotating shaft.

[0014] The beneficial effects of this utility model are:

[0015] By using a flipping plate to flip the steel plate, the upper and lower pressure rollers can alternately apply pressure to the steel plate in both directions, avoiding the problem of surface impurities embedded due to repeated rolling in one direction. This reduces scratches or pits, improves flatness and thickness uniformity, and prevents premature embrittlement of local areas due to repeated unidirectional deformation, thereby improving the overall strength and ductility of the material and meeting the needs of high-end applications.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a steel plate production pressing and straightening equipment, including a support frame 1; it also includes conveying components and receiving supports 3. Two conveying components are provided at both ends of the support frame 1, and a tilting plate 5 is provided between the two conveying components. Two connecting shafts 4 are fixedly connected to both ends of the tilting plate 5. Two gears 401 are fixedly connected to both ends of one connecting shaft 4. Two sets of receiving supports 3 are fixedly connected above the support frame 1. One set of receiving supports 3 is movably connected to a connecting shaft 4 without gears 401, and the other set of receiving supports 3 is rotatably connected to another connecting shaft 4. A rack 6 is meshed below the gears 401 and slidably connected to a sliding rail 7. A connecting column 8 is fixedly connected below the rack 6, and a limit plate is fixedly connected to the connecting column 8. 9. A hydraulic rod 10 is fixedly connected to the limiting plate 9. The other end of the hydraulic rod 10 is fixedly connected to the output end of the hydraulic cylinder 11. The hydraulic cylinder 11 is fixedly connected to the support frame 1. The steel plate is placed on the conveying assembly and, after single-sided rolling, is conveyed to the top of the flipping plate 5. Then, the hydraulic cylinder 11 outputs pressure to the hydraulic rod 10, pushing the hydraulic rod 10 to move. The hydraulic rod 10 drives the limiting plate 9 to move. The limiting plate 9 drives the rack 6 to slide on the sliding track 7 through the connecting column 8. The rack 6 drives the gear 401 meshing above to rotate. The gear 401 drives the connecting shaft 4 to rotate, thereby realizing that the connecting shaft 4 drives the flipping plate 5 to rotate, completing the flipping of the steel plate and conveying the other side of the steel plate to the conveying assembly for rolling.

[0024] Please see Figures 1-5 In this embodiment, the flipping plate 5 is provided with several negative pressure suction cups 501, and a support platform 12 is provided below the flipping plate 5. The support platform 12 is fixedly connected to the support frame 1. When the steel plate falls onto the flipping plate 5, it is tightly attracted by the negative pressure suction cups 501 until the flipping is completed, and then the steel plate is released. The support platform 12 shares the pressure of the steel plate on the flipping plate 5. A through-hole groove 701 is provided below the sliding track 7. A connecting column 8 is slidably connected to the through-hole groove 701. When the connecting column 8 moves, it slides on the through-hole groove 701. The conveying assembly includes a first motor 201, a lower rotating shaft 202, a first belt 203, and a lower pressure roller 204. A motor 201 is fixedly connected to a support frame 1. The output end of the first motor 201 is fixedly connected to a lower rotating shaft 202, which is rotatably connected to the support frame 1. A first belt 203 is sleeved on the outside of the lower rotating shaft 202, and a lower pressure roller 204 is fixedly connected to the lower rotating shaft 202. When a steel plate is placed on the lower pressure roller 204, the first motor 201 is turned on, so that the first motor 201 outputs torque to the lower rotating shaft 202, which drives the first belt 203 sleeved on the outside of the lower rotating shaft 202 to rotate, thereby driving all the lower rotating shafts 202 to rotate. The lower rotating shafts 202 drive the lower pressure rollers 204 to rotate, thus realizing the conveying of the steel plate.

[0025] Please see Figures 1-3In this embodiment, several distance sensors 13 are fixedly connected to the support frame 1, and two gantry frames 14 are fixedly connected to both sides of the support frame 1. The distance sensors 13 are electrically connected to second motors 15. The distance sensors 13 measure and transmit electrical signals to the second motors 15 to control the thickness of the rolled steel plate. The gantry frames 14 are used to achieve height changes. The distance sensors 13 in this device are ZLDS100 sensors. Two second motors 15 are fixedly connected to the upper ends of the gantry frames 14. The output ends of the second motors 15 are fixedly connected to threaded rods 16, which are rotatably connected to the gantry frames 14. A sliding frame 17 is threadedly connected to the threaded rod 16. The second motors 15 output torque to the threaded rods 16. The rod 16 rotates, causing the sliding frame 17, which is threaded onto the rod 16, to move vertically to a predetermined height. A third motor 18 is fixedly connected to the sliding frame 17, and an upper rotating shaft 19 is fixedly connected to the output end of the third motor 18. The upper rotating shaft 19 is rotatably connected to the sliding frame 17, and a second belt 20 is sleeved on the outside of the upper rotating shaft 19. An upper pressure roller 21 is fixedly connected to the upper rotating shaft 19. The third motor 18 outputs torque to the upper rotating shaft 19, causing it to rotate. The upper rotating shaft 19 drives the second belt 20 to rotate, thereby realizing the rotation of all the upper rotating shafts 19. The upper rotating shaft 19 drives the upper pressure roller 21 to rotate, applying pressure to the steel plate and completing single-sided rolling.

[0026] During operation, the steel plate is placed on the lower pressure roller 204. The first motor 201 is turned on, outputting torque to the lower rotating shaft 202, which drives the first belt 203 sleeved on the outside of the lower rotating shaft 202 to rotate. This, in turn, drives all the lower rotating shafts 202 to rotate, which in turn drives the lower pressure roller 204 to rotate, thus conveying the steel plate. Simultaneously, the distance sensor 13 measures the distance and transmits the electrical signal to the second motor 15. The second motor 15 outputs torque to the threaded rod 16, causing the threaded rod 16 to rotate. This causes the sliding frame 17, which is threaded onto the threaded rod 16, to move vertically to a predetermined height. Then, the third motor 18 outputs torque to the upper rotating shaft 19, causing the upper rotating shaft 19 to move vertically to a predetermined height. The upper rotating shaft 19 drives the second belt 20 to rotate, thereby realizing the rotation of all the upper rotating shafts 19. The upper rotating shaft 19 drives the upper pressure roller 21 to rotate, applying pressure to the steel plate to complete single-sided rolling. After single-sided rolling, the steel plate is conveyed to the top of the flipping plate 5. Then, the hydraulic cylinder 11 outputs pressure to the hydraulic rod 10, pushing the hydraulic rod 10 to move. The hydraulic rod 10 drives the limit plate 9 to move. The limit plate 9 drives the rack 6 to slide on the sliding track 7 through the connecting column 8. The rack 6 drives the gear 401 meshing above to rotate. The gear 401 drives the connecting rotating shaft 4 to rotate, thereby realizing the rotation of the flipping plate 5 by the connecting rotating shaft 4, completing the flipping of the steel plate, and conveying the other side of the steel plate to the conveying assembly for rolling.

[0027] Through the above steps, the steel plate is flipped using the flipping plate 5, allowing the upper pressure roller 21 and the lower pressure roller 204 to alternately apply pressure to the steel plate in both directions. This avoids the problem of surface impurities being embedded due to repeated rolling in one direction, thereby reducing scratches or pits, improving flatness and thickness uniformity, and preventing premature embrittlement of local areas due to repeated unidirectional deformation. This improves the overall strength and ductility of the material, meets the needs of high-end applications, and solves the problem that traditional steel plate production pressing equipment lacks an automatic flipping mechanism, affecting the appearance of the product or the quality of subsequent coatings, and cannot achieve symmetrical rolling processes, thus weakening the product's market competitiveness.
