Description

Technical Field

[0001] This utility model relates to the field of high magnetic permeability oriented silicon steel coil processing technology, specifically to an annealing device for high magnetic permeability oriented silicon steel coil with a protective mechanism. Background Technology

[0002] High-permeability grain-oriented silicon steel coils are a special type of silicon steel coil. These coils have high magnetic permeability and low coercivity, and are commonly used in the manufacture of power equipment such as transformers and motors. During the production process, high-permeability grain-oriented silicon steel coils are annealed to eliminate the internal stress generated during processing and restore the electromagnetic properties of the material.

[0003] Traditional annealing equipment for high-permeability grain-oriented silicon steel coils lacks adequate protection on both sides of the furnace opening during loading and unloading, posing a safety hazard by preventing external objects from entering the opening. Therefore, we propose an annealing equipment for high-permeability grain-oriented silicon steel coils with a protective mechanism to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an annealing device for high-permeability magnetically oriented silicon steel coils with a protective mechanism, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an annealing device for high-permeability magnetic oriented silicon steel coils with a protective mechanism, comprising an annealing furnace body, a support frame installed at the bottom of the annealing furnace body, a furnace cavity provided inside the annealing furnace body, a furnace door provided at the front end of the furnace cavity, a feeding platform installed at the bottom of the furnace cavity, mounting grooves provided on both sides of the annealing furnace body, and a receiving groove provided at the front end of each mounting groove, a telescopic cylinder installed at one end of each mounting groove via a mounting seat, and a protective plate installed at the front end of each telescopic cylinder.

[0006] As a further technical solution of this utility model, the cross-section of the protective plate is smaller than the cross-section of the storage groove, and the protective plate and the storage groove form an interlocking structure.

[0007] As a further technical solution of this utility model, a plurality of telescopic cylinders are provided, and the plurality of telescopic cylinders are symmetrically distributed about the central axis of the protective plate.

[0008] As a further technical solution of this utility model, both sides of the top of the feeding platform are provided with sliding grooves, and guide rods are installed inside the sliding grooves. Slider blocks are movably provided on the outer side walls of the guide rods, and guide grooves are provided inside the sliders. A conveying platform is installed at the top of the sliders, and a pulling block is installed at the front end of the conveying platform. Connecting blocks are fixed on both sides of the top of the conveying platform, and second threaded rods are movably provided inside the connecting blocks. A rotating block is installed on one side of the second threaded rod, and a limit block is installed on the other side of the second threaded rod.

[0009] As a further technical solution of this utility model, the limiting blocks are provided in four sets, and the four sets of limiting blocks are symmetrically distributed about the central axis of the conveyor table.

[0010] As a further technical solution of this utility model, the cross-section of the slider is larger than the cross-section of the guide rod, and the slider and the guide rod form a sliding structure.

[0011] As a further technical solution of this utility model, a frame is installed on both sides of the top of the annealing furnace body. A first threaded rod is movably arranged inside the left frame of the top of the annealing furnace body, and a servo motor is installed at the top of the first threaded rod. A sliding rod is installed inside the right frame of the top of the annealing furnace body. A movable frame is movably arranged on the outer side wall of the first threaded rod and the sliding rod, and the front end of the movable frame is fixed to the surface of the furnace door.

[0012] As a further technical solution of this utility model, the movable frame and the slide rod form a sliding structure, and the movable frame and the first threaded rod form a threaded connection.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the high magnetic permeability oriented silicon steel coil annealing device with protective mechanism not only realizes the protective mechanism, making loading and unloading more convenient, but also realizes the automatic movement of the furnace door of the annealing furnace body to open the annealing furnace body;

[0014] By providing components such as storage slots, protective plates, telescopic cylinders, and installation slots on both sides of the annealing furnace body, when the furnace cavity is opened for loading and unloading during use, the aforementioned components can push the protective plates to unfold on both sides of the annealing furnace body, protecting the loading and unloading process and preventing external objects from extending into the furnace cavity from both sides of the annealing furnace body during loading and unloading, thus avoiding safety hazards.

[0015] By setting up a conveyor table, chute, and slider, the annealing furnace body facilitates the conveying of materials during loading and unloading. By setting up components such as a second threaded rod, connecting block, and limiting block on both sides of the top of the conveyor table, the high magnetic permeability oriented silicon steel coil can be limited, so that it can be stably loaded and unloaded, making loading and unloading more convenient.

[0016] By installing components such as a servo motor, a first threaded rod, and a slide rod at the top of the annealing furnace body, the furnace door needs to be moved open to open the furnace cavity inside the furnace body during use. Due to the installation of the above components, the annealing device can automatically pull the furnace door to open the furnace cavity, which greatly increases the convenience of opening the annealing device and makes it more convenient to use.

[0022] 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.

[0023] Please see Figure 1-4This utility model provides an embodiment: an annealing device for high-permeability magnetic oriented silicon steel coils with a protective mechanism, including an annealing furnace body 1, a support frame 9 installed at the bottom of the annealing furnace body 1, a furnace cavity 11 inside the annealing furnace body 1, a furnace door 2 at the front end of the furnace cavity 11, a feeding platform 10 installed at the bottom inside the furnace cavity 11, mounting grooves 15 on both sides inside the annealing furnace body 1, and a receiving groove 7 at the front end of each mounting groove 15, a telescopic cylinder 14 installed at one end of each mounting groove 15 via a mounting base 16, a protective plate 8 installed at the front end of each telescopic cylinder 14, the cross-section of the protective plate 8 being smaller than the cross-section of the receiving groove 7, the protective plate 8 and the receiving groove 7 forming a locking structure, so that the protective plate 8 can be stored inside the receiving groove 7 when protection is not needed, and a plurality of telescopic cylinders 14 are provided, the plurality of telescopic cylinders 14 being symmetrically distributed about the central axis of the protective plate 8, pushing the protective plate 8 to move back and forth stably;

[0024] Specifically, such as Figure 1 and Figure 2 As shown, when the annealing furnace body 1 is loading and unloading high-permeability magnetic oriented silicon steel coils, the telescopic cylinder 14 is activated to push the protective plate 8 at the front end to move out from the inside of the receiving groove 7 and unfold on both sides of the annealing furnace body 1 to protect the loading and unloading of high-permeability magnetic oriented silicon steel coils.

[0025] The top of the feeding platform 10 is provided with two sides of the sliding groove 22. The sliding groove 22 is installed with a guide rod 25. The outer side wall of the guide rod 25 is movably provided with a slider 23. The slider 23 is provided with a guide groove 24. The top of the slider 23 is provided with a conveying platform 13. The front end of the conveying platform 13 is provided with a pulling block 12. The top of the conveying platform 13 is fixed with two sides of the top of the conveying platform 13. The connecting block 19 is movably provided with a second threaded rod 18 inside the connecting block 19. A rotating block 21 is installed on one side of the second threaded rod 18. A limit block 20 is installed on the other side of the second threaded rod 18. There are four sets of limit blocks 20. The four sets of limit blocks 20 are symmetrically distributed about the central axis of the conveying platform 13. The symmetrically distributed limit blocks 20 provide more stable limiting for the high magnetic permeability oriented silicon steel coil. The cross section of the slider 23 is larger than the cross section of the guide rod 25. The slider 23 and the guide rod 25 form a sliding structure, which makes the conveying platform 13 move back and forth stably for loading and unloading.

[0026] Specifically, such as Figure 1 and Figure 3As shown, the conveyor table 13 is then pulled by the pull block 12 and the slide block 23 moves the conveyor table 13 out of the furnace cavity 11 by sliding on the outer wall of the guide rod 25. The high magnetic permeability oriented silicon steel coil to be annealed is then placed on the conveyor table 13. Next, the rotating block 21 is held in sequence to rotate the second threaded rod 18. The rotation of the second threaded rod 18 pushes the limiting block 20 on one side to fit against both sides of the high magnetic permeability oriented silicon steel coil placed on the conveyor table 13, so that the high magnetic permeability oriented silicon steel coil is stably placed inside the conveyor table 13. Then the conveyor table 13 is pushed back into the furnace cavity 11 to complete the feeding.

[0027] Both sides of the top of the annealing furnace body 1 are equipped with a frame 5. The first threaded rod 3 is movably installed inside the left frame 5 at the top of the annealing furnace body 1, and a servo motor 4 is installed at the top of the first threaded rod 3. The slide rod 6 is installed inside the right frame 5 at the top of the annealing furnace body 1. The outer walls of the first threaded rod 3 and the slide rod 6 are movably equipped with a movable frame 17, and the front end of the movable frame 17 is fixed to the surface of the furnace door 2. The movable frame 17 and the slide rod 6 form a sliding structure, and the movable frame 17 and the first threaded rod 3 form a threaded connection. The design of the threaded connection and the sliding structure drives the furnace door 2 to move up and down stably.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, when the furnace cavity 11 of the annealing furnace body 1 is opened, the servo motor 4 is started to drive the first threaded rod 3 to rotate, and then the furnace door 2 is pulled upward through the guide of the slide rod 6 to open the furnace cavity 11 for corresponding loading and unloading operations. After the operation is completed, the servo motor 4 is started again to drive the first threaded rod 3 to rotate in the opposite direction, and then the furnace door 2 is pushed downward through the guide of the slide rod 6 to return to the front end of the furnace cavity 11 to protect the furnace cavity 11.

[0029] Working principle: When using this utility model, the servo motor 4 is started, driving the first threaded rod 3 to rotate. The guide rod 6 then pulls the furnace door 2 upwards, opening the furnace chamber 11. Next, the pulling block 12 pulls the conveyor table 13, and the slider 23 slides along the outer wall of the guide rod 25, moving the conveyor table 13 out of the furnace chamber 11. Then, the high-permeability magnetic oriented silicon steel coil to be annealed is placed above the conveyor table 13. Next, the rotating block 21 is grasped in sequence, pushing the limiting block 20 on one side to fit against the high-permeability magnetic oriented silicon steel coil placed above the conveyor table 13. The oriented silicon steel coil is clamped, and then the conveyor table 13 is pushed back into the furnace cavity 11. The servo motor 4 drives the first threaded rod 3 to rotate in the opposite direction, causing the furnace door 2 to descend and seal the furnace cavity 11. Then, the annealing furnace body 1 is opened to anneal the high magnetic permeability oriented silicon steel coil. After the work is completed, the high magnetic permeability oriented silicon steel coil can be taken out. During the loading and unloading process of the high magnetic permeability oriented silicon steel coil, the telescopic cylinder 14 is activated to push the front protective plate 8 out from the inside of the storage slot 7 and unfold on both sides of the annealing furnace body 1 to protect the loading and unloading of the high magnetic permeability oriented silicon steel coil.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
