Description

Technical Field

[0001] This utility model relates to the field of non-oriented silicon steel production technology, and in particular to a continuous production line for non-oriented silicon steel. Background Technology

[0002] Non-oriented silicon steel is an alloy material with iron and silicon as the main components. It belongs to an important type of electrical steel (silicon steel sheet). It is named for its uniform magnetic permeability in an alternating magnetic field. The main silicon content is 0.5% to 4.5%, with the remainder being iron and a small amount of impurities. The internal grain orientation is irregular. The magnetic permeability is basically the same regardless of the direction of the magnetic field applied. It is suitable for equipment such as motors that require multi-directional magnetic conduction.

[0003] Currently, in traditional continuous production lines for non-oriented silicon steel, a guiding mechanism is used before hot rolling the billet to prevent it from shifting. However, this method has its shortcomings: the guiding mechanism lacks the ability to adaptively adjust to billets of different widths, making it difficult to effectively restrict the billet when faced with billets of multiple specifications. This leads to uneven stress on the billet during the hot rolling process, ultimately resulting in quality defects such as incomplete rolling.

[0004] To address the above issues, a continuous production line for non-oriented silicon steel is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a non-oriented silicon steel continuous production line, which aims to improve the problems in the prior art that the guiding mechanism cannot be adjusted according to the casting billet of different widths, and the distance between the spraying roller and the silicon steel sheet cannot be adjusted according to the silicon steel sheet of different thicknesses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A continuous production line for non-oriented silicon steel includes a base, a conveyor mounted on the top of the base, a limit component on the right side of the top of the conveyor, a support frame fixedly connected to the left side of the top of the base, an adjustment component on the inner top wall of the support frame, a hot rolling mill mounted in the middle of the top of the base, and an annealing furnace mounted on the top of the base, the annealing furnace being installed between the support frame and the hot rolling mill.

[0008] The limiting component includes two support plates, the bottom of which is fixedly connected to the top of the conveyor. A housing is fixedly connected to the top of the two support plates. A motor is fixedly connected to the top of the housing. A gear is fixedly connected to the output end of the motor. Two racks are slidably connected inside the housing. Both racks are meshed with the gear. An L-shaped rod is fixedly connected to the bottom of the rack. A limiting plate is fixedly connected to the end of the L-shaped rod away from the rack.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a cylinder, the top of which is fixedly connected to the inner top wall of the support frame. A connecting plate is fixedly connected to the output end of the cylinder. Sliding rods are slidably connected to both ends of the connecting plate. Springs are sleeved on the outer periphery of both sliding rods. A U-shaped frame is fixedly connected to the bottom of the two sliding rods. A second motor is fixedly connected to the outer side of the U-shaped frame. A spraying roller is fixedly connected to the output end of the second motor. The spraying roller is rotatably connected to the side wall of the U-shaped frame.

[0011] As a further description of the above technical solution:

[0012] A liquid storage tank is fixedly connected to the top of the support frame, a drain pipe is fixedly connected to the outside of the liquid storage tank, the outside of the drain pipe is fixedly connected to the inside of the support frame, and connecting hoses are fixedly connected to both ends of the drain pipe.

[0013] As a further description of the above technical solution:

[0014] The gear is rotatably connected inside the housing, and the end of the L-shaped rod away from the rack passes through and is slidably connected inside the support plate;

[0015] As a further description of the above technical solution:

[0016] The top end of the spring is fixedly connected to the bottom of the connecting plate, and the bottom end of the spring is fixedly connected to the top of the U-shaped frame;

[0017] As a further description of the above technical solution:

[0018] The connecting hose passes through and is fixedly connected inside the connecting plate, and the connecting hose passes through and is fixedly connected inside the U-shaped frame;

[0019] As a further description of the above technical solution:

[0020] Two slide rails are fixedly connected to the bottom wall of the outer casing, and the bottom of the rack is slidably connected to the top of the slide rails.

[0021] As a further description of the above technical solution:

[0022] An inlet pipe is fixedly connected to the top of the liquid storage tank.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when it is necessary to adjust the distance between the two limiting plates for casting billets of different widths, the motor is started to drive the gear to rotate. Since the gear meshes with the rack, the rotation of the gear will drive the rack and L-shaped rod to move synchronously, thereby realizing the dynamic adjustment of the distance between the limiting plates. This ensures that the casting billet maintains a stable transmission posture before hot rolling, and avoids uneven stress on the casting billet during hot rolling due to billet deviation, which will ultimately cause quality defects such as incomplete rolling.

[0025] 2. In this utility model, the connecting plate is driven by a cylinder, and the power is transmitted through the sliding rod to drive the U-shaped frame to achieve vertical displacement, thereby adjusting the working height of the spraying roller. This allows it to adapt to silicon steel sheets of different thicknesses and ensure uniform coating coverage. At the same time, the spring sleeved on the outer periphery of the sliding rod plays a buffering role. When the spraying roller contacts the surface of the silicon steel sheet, the spring is compressed and undergoes elastic deformation, effectively buffering the contact pressure and avoiding damage to the silicon steel sheet due to excessive squeezing, thereby improving the reliability of the spraying process and the stability of product quality.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a non-oriented silicon steel continuous production line, including a base 1, which provides stable support to ensure stable operation of the equipment. A conveyor 2 is installed on the top of the base 1 to transport silicon steel sheets. A limit component is provided on the right side of the top of the conveyor 2. A support frame 13 is fixedly connected to the left side of the top of the base 1. An adjustment component is provided on the inner top wall of the support frame 13. A hot rolling mill 3 is installed in the middle of the top of the base 1 to hot roll the transported billet. The billet can be rolled to the target thickness through hot rolling. An annealing furnace 4 is provided on the top of the base 1. After the billet is rolled, an annealing operation is performed to eliminate the internal residual stress of the silicon steel sheet. The annealing furnace 4 is installed between the support frame 13 and the hot rolling mill 3.

[0035] The limiting assembly includes two support plates 12, which support the limiting assembly and ensure its stability during operation. The bottoms of both support plates 12 are fixedly connected to the top of the conveyor 2. A housing 11 is fixedly connected to the top of the two support plates 12, protecting its internal structure. A motor 6 is fixedly connected to the top of the housing 11, and a gear 7 is fixedly connected to the output end of the motor 6. By starting the motor 6, it converts electrical energy into mechanical kinetic energy, thereby driving the gear 7 to rotate. A sliding connection is made inside the housing 11. Two racks 5 are meshed with gears 7. Based on the meshing transmission principle between gears 7 and racks 5, the rotation of gears 7 can be converted into linear motion of racks 5, so that the two racks 5 can move in opposite directions. An L-shaped rod 9 is fixedly connected to the bottom of rack 5. A limiting plate 10 is fixedly connected to the end of the L-shaped rod 9 away from rack 5. The limiting plate 10 can be driven to move synchronously with rack 5 through the L-shaped rod 9, so as to achieve the effect of appropriately adjusting the distance between the two limiting plates 10 according to the width of different casting blanks.

[0036] Reference Figure 2 , Figure 4 and Figure 5The adjustment assembly includes a cylinder 17, which serves as the core power source. The top of the cylinder 17 is fixedly connected to the inner top wall of the support frame 13. A connecting plate 18 is fixedly connected to the output end of the cylinder 17, which drives the connecting plate 18 to move. Sliding rods 8 are slidably connected to both ends of the connecting plate 18, and springs 19 are sleeved on the outer periphery of both sliding rods 8. A U-shaped frame 20 is fixedly connected to the bottom of the two sliding rods 8. Through the combined action of the sliding rods 8 and the springs 19, the U-shaped frame 20 can be driven when the connecting plate 18 moves. 0 Synchronous movement, a motor 22 is fixedly connected to the outside of the U-shaped frame 20, and a spraying roller 21 is fixedly connected to the output end of the motor 22. The motor 22 is used to drive the spraying roller 21 to rotate. The spraying roller 21 is rotatably connected to the side wall of the U-shaped frame 20. When the spraying roller 21 contacts the silicon steel sheet, it will drive the U-shaped frame 20 to move upward, thereby driving the sliding rod 8 to move and squeeze the spring 19. Through the buffer force provided by the spring 19, the squeezing force on the silicon steel sheet can be reduced, thereby avoiding damage to the silicon steel sheet due to excessive squeezing.

[0037] Reference Figure 2 and Figure 4 A liquid storage tank 14 is fixedly connected to the top of the support frame 13. The liquid storage tank 14 is used to store the spraying liquid. A drain pipe 15 is fixedly connected to the outside of the liquid storage tank 14. The drain pipe 15 is fixedly connected to the inside of the support frame 13. Both ends of the drain pipe 15 are fixedly connected to connecting hoses 16. When the drain pipe 15 is opened, the spraying liquid in the liquid storage tank 14 can flow into the connecting hoses 16, and then the silicon steel sheet can be sprayed.

[0038] Reference Figure 3 Gear 7 is rotatably connected inside the housing 11. The end of L-shaped rod 9 away from rack 5 passes through and is slidably connected inside support plate 12. When gear 7 is driven by external force, it will indirectly drive L-shaped rod 9 to move, so that it passes through support plate 12.

[0039] Reference Figure 5 The top end of the spring 19 is fixedly connected to the bottom of the connecting plate 18, and the bottom end of the spring 19 is fixedly connected to the top of the U-shaped frame 20. The spring 19 is used to connect the connecting plate 18 and the U-shaped frame 20 together. When the U-shaped frame 20 moves upward, it will compress the spring 19, thereby allowing the spring 19 to store elastic potential energy.

[0040] Reference Figure 4 The connecting hose 16 passes through and is fixedly connected inside the connecting plate 18. The connecting hose 16 passes through and is fixedly connected inside the U-shaped frame 20. The connecting hose 16 is made of flexible material, so that when the U-shaped frame 20 and the connecting plate 18 are moved, the connecting hose 16 will not affect their normal operation.

[0041] Reference Figure 3Two slide rails 24 are fixedly connected to the bottom wall of the outer shell 11. The bottom of the rack 5 is slidably connected to the top of the slide rail 24. By setting the slide rail 24, the friction between the rack 5 and the outer shell 11 can be reduced, so that the rack 5 can slide stably inside the outer shell 11.

[0042] Reference Figure 1 The top of the liquid storage tank 14 is fixedly connected to the liquid inlet pipe 23. By opening the liquid inlet pipe 23, spraying liquid can be added to the liquid storage tank 14.

[0043] Working principle: When it is necessary to adjust the distance between the two limiting plates 10 according to different billets, start motor 6, so that the output end of motor 6 drives gear 7 to rotate. Since gear 7 is meshed with rack 5, the rotation of gear 7 will drive rack 5 to move, which in turn drives L-shaped rod 9 to move, thereby achieving the effect of adjusting the distance between the two limiting plates 10, so as to adapt to billets of different widths and ensure that they remain stable before hot rolling.

[0044] When spraying silicon steel sheets, cylinder 17 is activated, causing the connecting plate 18 to move. Then, the U-shaped frame 20 moves via the sliding rod 8, which in turn moves the spraying roller 21 up and down to accommodate silicon steel sheets of different thicknesses and ensure uniform spraying. A spring 19 is also fitted around the outer periphery of the sliding rod 8. When the spraying roller 21 contacts the silicon steel sheet, it moves the U-shaped frame 20 upward, which in turn moves the sliding rod 8 upward and compresses the spring 19. The spring 19 reduces the pressure on the silicon steel sheet, thus preventing excessive compression.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
