Description

Technical Field

[0001] The present invention relates to the technical field of special-shaped steel rolling mills. More specifically, the present invention relates to a special-shaped steel rolling mill with a rolling assembly. Background Art

[0002] Rolling is a metal processing technology. The metal billet passes through the gap (various shapes) between a pair of rotating rolling mills. Due to the compression of the rolling mills, the cross-section of the material is reduced and the length is increased by a pressure processing method. The metal billet passes through the gap (various shapes) between a pair of rotating rolling mills. Due to the compression of the rolling mills, the cross-section of the material is reduced and the length is increased by a pressure processing method. This is the most commonly used production method for producing steel, mainly used to produce profiles, plates, and pipes. It is divided into two types: hot rolling and cold rolling.

[0003] Currently, when rolling special-shaped steel, due to reasons such as the complex and asymmetrical profile of the special-shaped steel, it is easy to cause lateral offsets on both sides of the special-shaped structure of the steel during the rolling process, and then cause the steel to skew during the processing process, and then cause uneven thickness of the finished rolled steel, affecting the actual processing quality and being inconvenient for actual use. Therefore, the present invention proposes a special-shaped steel rolling mill with a rolling assembly to solve the above problems. Summary of the Invention

[0020] The technical effects and advantages of the present invention:

[0021] In the present invention, by arranging a first limiting frame and a second limiting frame on both sides of the steel to be rolled, and when the steel plate is deflected, the first limiting frame as a whole can be synchronously deflected along with the side of the steel plate, and then combined with the gear disk and the arc gear, the moving plate is reversely deflected, and then the second limiting frame as a whole is translated inside the limiting block and translated close to the vertical direction of the inclination of the second limiting frame to limit the other side of the deflected steel plate until the deflected steel plate is rectified and kept moving in a straight state between the first rolling mill and the second rolling mill, thereby avoiding the problem that the steel plate is deflected and stressed unevenly during the rolling process, resulting in deformation;

[0022] In the present invention, by arranging mutually matching half-circle grooves and limiting balls on the outer walls of the first rolling mill and the second rolling mill, when the first rotating shaft drives the first rolling mill as a whole to rotate, the first rotating ring and the second rotating ring as a whole are synchronously rotated, and then combined with the mutual limitation of the limiting ball and the half-circle groove, the first rolling mill and the second rolling mill as a whole can always rotate on the same vertical plane, thereby avoiding the problem that the first rolling mill and the second rolling mill generate horizontal acting forces and displace during the process of pressing the special-shaped structure, resulting in uneven rolling thickness of the steel plate;

[0023] When the first rotating shaft drives the first rolling mill to rotate as a whole in the present invention, the position of the first magnetic attracting block changes. When the first magnetic attracting block rotates close to the second magnetic attracting block, the second magnetic attracting block can be attracted to move upward, so that the heat dissipation gas inside the air storage chamber is blown out through the first air outlet pipe and the second air outlet pipe. When the first magnetic attracting block moves away from the second magnetic attracting block, the second magnetic attracting block rebounds and returns to its original position integrally in combination with the telescopic spring. In this way, the heat dissipation gas blown out through the second air outlet pipe is continuously blown out in an intermittent state, so as to cool and dissipate heat from the surface of the steel plate intermittently, thus avoiding problems such as indentation caused by too large a temperature difference on the surface of the steel plate due to excessive contact with cold air at one time.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Referring to the attached drawings of the specification Figures 1 - 10 , a special-shaped steel rolling mill with a rolling assembly according to an embodiment of the present invention is as Figure 1 shown, and includes a support table mechanism 1. A rolling mechanism 2 is fixedly installed on the top of the support table mechanism 1;

[0037] A positioning mechanism 3 is fixedly installed on the outer wall of the rolling mechanism 2. A cooling mechanism 4 is fixedly installed inside the support table mechanism 1. One side of the positioning mechanism 3 is fixedly connected with a deviation rectifying mechanism 5. Combining Figure 4 shown, the support table mechanism 1 includes a first base 101. A second base 102 is fixedly installed on one side of the first base 101. Two first side plates 103 are fixedly installed on the top of the second base 102. Second side plates 104 are fixedly installed on the tops of the two first side plates 103. Combining Figure 6 and Figures 8 - 10As shown, the deviation rectifying mechanism 5 includes a supporting bracket 51 horizontally arranged between two second side plates 104. A gear disc 52 is rotatably installed on one side of the supporting bracket 51. A first limiting frame 53 is fixedly connected to one side of the gear disc 52. A first limiting shaft 54 is rotatably installed on one side of the supporting bracket 51. An arc gear 56 meshing with the gear disc 52 is fixedly installed on the outer wall of the first limiting shaft 54. In the normal state, the vertical central plane of the first limiting frame 53 is parallel to one side of the second side plate 104. When the first limiting frame 53 is skewed as a whole, the gear disc 52 can be deflected as a whole. Then, combined with the arc gear 56 meshing with it, the moving plate 55 can be deflected around the center point of the first limiting shaft 54 as a whole, and the deflection directions of the gear disc 52 and the moving plate 55 are opposite. At the same time, a second limiting shaft fixedly connected to the supporting bracket 51 is rotatably installed at the horizontal center line position of the moving plate 55. A third limiting shaft 57 is rotatably installed at the top of the moving plate 55. A second limiting frame 58 is fixedly installed on the outer wall of the third limiting shaft 57. The second limiting frame 58 and the first limiting frame 53 are parallel to each other in the normal state. Limiting blocks 59 are fixedly installed on both sides of the supporting bracket 51. The second limiting frame 58 is slidably installed inside the two limiting blocks 59. Combined with Figure 10 As shown, a second supporting plate 515 is fixedly installed on one side of the second limiting frame 58. A first supporting plate 514 is fixedly installed on one side of the supporting bracket 51. An engaging frame 516 rotatably connected to the second supporting plate 515 is rotatably installed on one side of the first supporting plate 514. The purpose of such a setting is that when the moving plate 55 is deflected, through the setting of the engaging frame 516, it is kept in a parallel deflection state with the moving plate 55. When the moving plate 55 is deflected in the reverse direction as a whole with the deflection of the first limiting frame 53, the moving plate 55 can drive the second limiting frame 58 to displace as a whole. Due to the limitation of the limiting blocks 59, the second limiting frame 58 can only move horizontally between the two limiting blocks 59 as a whole, so that the second limiting frame 58 always maintains a straight state and supports on one side of the moving plate 55. Thus, when the first limiting frame 53 and the second limiting frame 58 are synchronously limited on both sides of the steel plate, and the steel plate moves between the first rolling roller 22 and the second rolling roller 24 for rolling. During this process, when the steel plate is offset, the first limiting frame 53 can be synchronously skewed along with the side of the steel plate. Then, combined with the gear disc 52 and the arc gear 56, the moving plate 55 is deflected in the reverse direction. Then, the second limiting frame 58 moves horizontally inside the limiting blocks 59 and moves close to the vertical direction in which the second limiting frame 58 is inclined to limit the other side of the skewed steel plate until the skewed steel plate is rectified to keep it moving straight between the first rolling roller 22 and the second rolling roller 24, thereby avoiding the problem of deformation of the steel plate caused by uneven stress during rolling.

[0038] Further, referring to Figures 6 - 7 As shown, on one side of the first limiting frame 53 and the second limiting frame 58, threaded rods 510 are fixedly installed. On the outer wall of the threaded rod 510, a first fixed sleeve 511 is fixedly installed. A second fixed sleeve 512 is engaged with the outer wall of the threaded rod 510. Rotating rollers 513 are rotatably installed on one side of the first fixed sleeve 511 and the second fixed sleeve 512. The purpose of such a setting is that when limiting the use of steel plates with different thicknesses, by placing the steel plate between the first fixed sleeve 511 and the second fixed sleeve 512, and then rotating and adjusting the rotating roller 513 to move it closer to the first fixed sleeve 511 on the outer wall of the second fixed sleeve 512, so that after clamping both sides of the steel plate, during the movement of the steel plate, it can move while adhering to the outer wall of the rotating roller 513. At the same time, when limiting the use of steel plates with different thicknesses, the overall height of the first limiting frame 53 and the second limiting frame 58 should be adjusted synchronously, so that the first fixed sleeve 511 and the second fixed sleeve 512 can contact both sides of the steel plate more closely. Referring to Figure 7 and Figure 9 As shown, on both sides of the bearing bracket 51, second fixed seats 518 are fixedly installed. Second sliding grooves 517 are opened inside the second side plate 104. The second fixed seats 518 are slidably installed inside the second sliding grooves 517. A second threaded rod 519 is rotatably installed on one side of the second side plate 104. The second fixed seats 518 are engaged with the outer wall of the second threaded rod 519. The second side plate 104 and the second threaded rod 519 are arranged in a one-to-one correspondence, and the number of both the second side plate 104 and the second threaded rod 519 is set to two. At one end of the two second threaded rods 519 passing through the top of the second side plate 104, connecting transmission gears 520 are provided. Synchronous belts 521 are engaged with the outer walls of the two transmission gears 520. The bottom of the second threaded rod 519 is fixedly connected with a motor for driving its rotation. The purpose of such a setting is that when starting the motor to rotate the second threaded rod 519, through the setting of the transmission gears 520 and the synchronous belts 521, the other second threaded rod 519 rotates synchronously, so that the second fixed seats 518 move and adjust on the outer wall of the second threaded rod 519, thereby synchronously changing the overall height of the first limiting frame 53 and the second limiting frame 58, with stronger practicability and more convenient for actual use.

[0039] As a further expansion of this solution, referring to Figure 4 As shown, the rolling mechanism 2 includes a first rotating shaft 21 rotatably installed between two first side plates 103. On the outer wall of the first rotating shaft 21, a first rolling roller 22 is fixedly installed. A second rotating shaft 23 parallel to it is provided at the top of the first rotating shaft 21. On the outer wall of the second rotating shaft 23, a second rolling roller 24 is fixedly installed. Combining Figure 5As shown in the figure, a convex block 25 is fixedly installed on the outer wall of the first rolling roll 22, and a groove 26 that matches the convex block 25 is formed on the outer wall of the second rolling roll 24. The purpose of this setting is that when the steel plate is placed between the first rolling roll 22 and the second rolling roll 24 for rolling treatment, when the steel plate passes through the convex block 25 and the groove 26, it can be subjected to a longitudinal pressing force to deform the steel plate, thereby forming a special-shaped structure of the steel plate. Among them, to avoid that while the convex block 25 and the groove 26 match each other and generate a longitudinal extrusion force on the steel plate, a horizontal force is generated, which in turn causes the first rolling roll 22 and the second rolling roll 24 to move left and right as a whole, and then leads to the problem of uneven thickness on both sides of the rolled steel plate. Refer to Figure 5 As shown in the figure, the positioning mechanism 3 includes first rotating rings 31 fixedly installed at both ends of the first rolling roll 22. A plurality of sleeves 32 are fixedly installed on the outer walls of the two first rotating rings 31 in an annular and equally spaced manner. Plug rods 33 are installed in the inner cavities of the plurality of sleeves 32 in a vertically sliding manner. One end of the plug rod 33 is fixedly connected with a limiting ball 34. A return spring 35 is fixedly installed between the limiting ball 34 and the sleeve 32. Second rotating rings 36 are fixedly installed at both ends of the second rolling roll 24. A plurality of semi-circular grooves 37 are formed on the outer walls of the two second rotating rings 36 in an annular and equally spaced manner. The limiting ball 34 is inserted into the inner cavity of the semi-circular groove 37. The purpose of this setting is that when the first rotating shaft 21 drives the first rolling roll 22 to rotate as a whole, the second rotating shaft 23 and the second rolling roll 24 also rotate synchronously. During this process, the first rotating ring 31 and the second rotating ring 36 also rotate synchronously. Then, combined with the mutual limitation of the limiting ball 34 and the semi-circular groove 37, the first rolling roll 22 and the second rolling roll 24 can always rotate on the same vertical plane, thereby avoiding displacement due to horizontal forces generated by the first rolling roll 22 and the second rolling roll 24 during the process of pressing the special-shaped structure, and then avoiding the problem of uneven rolling thickness of the steel plate.

[0040] Furthermore, refer to Figure 5As shown in the figure, first chutes 27 are provided in a penetrating manner inside both of the two first side plates 103. A first fixing seat 28 fixedly connected to the first chute 27 is rotatably mounted on the outer wall of the first rotating shaft 21. An adapter seat 29 is rotatably mounted on the outer wall of the second rotating shaft 23. The adapter seat 29 is slidably mounted inside the first chute 27. The purpose of such a setting is to keep the overall position of the first rotating shaft 21 and the first rolling roller 22 fixed all the time. When it is necessary to roll steel plates with different thicknesses, the overall height of the second rotating shaft 23 and the second rolling roller 24 can be adjusted, which is more convenient to adjust. At the same time, a first threaded rod 211 is rotatably mounted on the top of the second base 102. A threaded sleeve 210 fixedly connected to the adapter seat 29 is engaged with the outer wall of the first threaded rod 211. The purpose of such a setting is that when the first threaded rod 211 is rotated, the threaded sleeve 210 can drive the adapter seat 29 to move up and down on its outer wall, so that the adapter seat 29 drives the overall height of the second rotating shaft 23 and the second rolling roller 24 to be adjusted, so that the distance between the first rolling roller 22 and the second rolling roller 24 is changed, and the distance between the raised blocks 25 and the grooves 26 is adjusted synchronously. During this process, in combination with the settings of the sleeve 32, the insertion rod 33 and the return spring 35, when the limiting ball 34 comes into contact with and presses against the semi-circular groove 37, the insertion rod 33 can be synchronously squeezed and contracted into the inner cavity of the sleeve 32, so as to synchronously limit the overall position of the first rolling roller 22 and the second rolling roller 24, and further make the device more stable and practical when rolling and adjusting steel plates with different thicknesses.

[0041] As a further expansion of this solution, referring to Figures 2 - 3As shown in the figure, the temperature reduction mechanism 4 includes a first empty slot 41 opened in the inner cavity of the second base 102. A second empty slot 42 is opened at the top of the second base 102. Two inclined baffles 105 are fixedly installed at the top of the second base 102. The two baffles 105 are symmetrically arranged with respect to the vertical center line of the second empty slot 42. The purpose of such a setting is to enable the baffles 105 to surround the flying debris generated during the rolling of the steel plate by the first rolling roll 22 and the second rolling roll 24 as a whole, and guide the flying debris to fall into the inside of the first empty slot 41 along the baffles 105. At the same time, an air storage chamber 43 is fixedly installed in the inner cavity of the first empty slot 41. An air inlet pipe 45 is communicated with the bottom of the air storage chamber 43. A plurality of first air outlet pipes 410 penetrating through the top of the second base 102 are communicated with the outer wall of the air storage chamber 43. The tops of the plurality of first air outlet pipes 410 are all communicated with second air outlet pipes 411 arranged in an inclined state. Among them, the top air outlet of each of the plurality of second air outlet pipes 411 is arranged towards the upper surface of the first rolling roll 22. The purpose of such a setting is to enable the heat dissipation gas transported into the air storage chamber 43 through the air inlet pipe 45 to be blown towards the upper surface of the first rolling roll 22 through the plurality of first air outlet pipes 410 and the second air outlet pipes 411, thereby blowing and cooling the rolled steel plate.

[0042] Among them, to avoid excessive temperature difference on the surface of the steel plate during continuous cooling of the steel plate during the rolling process, which may cause problems such as indentations and imprints on the surface of the steel plate, in combination with Figure 3 and Figure 5As shown, two first sealing blocks 44 are fixedly installed on the inner wall of the gas storage chamber 43. There is a gap between the two first sealing blocks 44, and a second sealing block 46 is installed in a vertically sliding state inside the gap between the two first sealing blocks 44. The top of the second sealing block 46 is fixedly connected to a piston rod 47 that penetrates through the top of the gas storage chamber 43 in a vertically sliding state. The top of the piston rod 47 is fixedly installed with an adapter plate 48. The top of the adapter plate 48 is fixedly installed with a second magnetic block 49. The bottom of the second magnetic block 49 is fixedly installed with a telescopic spring fixedly connected to the second base 102. In the normal state, the telescopic spring is in a contracted state, pulling the second magnetic block 49 and the adapter plate 48 downward as a whole. Subsequently, the adapter plate 48 presses the piston rod 47 synchronously, causing the second sealing block 46 to be inserted and blocked in the gap between the two first sealing blocks 44, so that the cooling gas entering the gas storage chamber 43 is divided into two parts by the first sealing block 44 and the second sealing block 46. When the second magnetic block 49 drives the adapter plate 48 and the piston rod 47 to move upward as a whole, causing the second sealing block 46 to be withdrawn from the gap between the first sealing blocks 44, the cooling gas can be discharged. Synchronously, a first magnetic block 212 is fixedly installed on the outer wall of the first rotating shaft 21. The first magnetic block 212 and the second magnetic block 49 are arranged in a mutually attracting state. The numbers of the second magnetic block 49 and the first magnetic block 212 are both set to two, and the two second magnetic blocks 49 and the first magnetic blocks 212 are symmetrically arranged about the vertical center line of the first roller 22. The purpose of such a setting is that when the first rotating shaft 21 drives the first roller 22 to rotate as a whole, the position of the first magnetic block 212 can be changed. When the first magnetic block 212 rotates close to the second magnetic block 49, it can attract the second magnetic block 49 to move upward, and then the second sealing block 46 moves upward as a whole, so that the cooling gas inside the gas storage chamber 43 is blown out through the first air outlet pipe 410 and the second air outlet pipe 411. When the first magnetic block 212 rotates away from the second magnetic block 49 as the first rotating shaft 21 rotates, the magnetic attraction force on the top of the second magnetic block 49 is lost, so that the second magnetic block 49 rebounds and returns to its original position as a whole in combination with the telescopic spring. Repeating this process, the cooling gas blown out through the second air outlet pipe 411 is continuously blown out intermittently, thereby performing intermittent cooling and heat dissipation on the surface of the steel plate, and avoiding problems such as indentation caused by excessive temperature difference on the surface of the steel plate due to excessive contact with cold air at one time.
