Description

Technical Field

[0001] This utility model relates to the technical field of blast furnace mud gun equipment for ironmaking, and in particular to a device for manufacturing carbonized fiber gun caps. Background Technology

[0002] In the field of blast furnace mud gun equipment, the gun cap, as a key component for plugging the taphole in the mud gun, often needs to withstand conditions such as erosion from molten iron, high temperatures, and impacts. Ordinary gun cap manufacturing methods struggle to produce caps capable of withstanding these conditions, especially carbonized fiber caps. To improve their high-temperature resistance, current technology uses carbide ceramic materials to make the gun cap and employs a high-energy laser beam to break down the surface, forming a carbonized fiber structural layer. This type of gun cap is typically cylindrical.

[0003] Ceramic is applied to the surface of the gun cap base, and then the ceramic is made into carbonized fibers using a carbonized fiber manufacturing device. The carbonized fibers have both toughness and high temperature resistance.

[0004] The curved structure of the cylindrical cannon cap means that the laser can only break it from a single plane. In order to complete the full coverage of the outer surface of the cannon cap, the rotation angle of the cannon cap must be adjusted manually or semi-automatically repeatedly. This process requires interrupting the processing and repositioning to achieve full coverage. The operation is cumbersome and time-consuming, resulting in low overall processing efficiency and difficulty in meeting the needs of large-scale production. Utility Model Content

[0005] Given that the curved surface structure of the existing cylindrical gun cap means that the laser can only break it from a single plane, and that multiple positioning operations are required to complete the full coverage of the outer surface of the gun cap, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a device for manufacturing carbon fiber cannon caps, the purpose of which is to perform comprehensive processing of the cannon caps in one molding process.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a carbon fiber cannon cap manufacturing device, including a processing chamber, an ultraviolet laser isolation door panel is slidably installed at the access port of the processing chamber, an angle adjustment component is installed at the bottom inside the processing chamber, a cannon cap body is detachably installed at the fixed end of the angle adjustment component, and L-shaped cavities are opened on both sides of the peripheral surface of the cannon cap body.

[0008] The angle adjustment component includes a rotary table installed inside the processing chamber. A rotating disk is longitudinally mounted on the rotating end of the rotary table. A servo motor is installed at the center of the top of the rotating disk. The drive end of the servo motor is fixedly connected to a frustum plate.

[0009] A displacement assembly is installed in the upper part of the processing chamber. A laser generator with a carbonization catalyst is fixed to the movable end of the displacement assembly, and a laser head is installed at the working end of the laser generator.

[0010] As an improved technical solution, a rotating seat is fixed to the top of the rotating end of the rotary table, and a dual-axis motor is installed in the middle of the top of the rotating seat. The two drive ends of the dual-axis motor are fixedly connected to rotating blocks, and the rotating blocks are welded to the bottom of the rotary disk.

[0011] As an improved technical solution, positioning blocks adapted to the vertical end of the L-shaped cavity are fixed on both sides of the top of the frustum plate. A second electric telescopic rod is installed on both sides of the top of the frustum plate in a back-to-back state. A pressure block that engages with the transverse end of the L-shaped cavity is installed on the movable end of the second electric telescopic rod.

[0012] As an improved technical solution, the displacement component includes a suspended bracket fixed inside the processing chamber, an L-shaped plate slidably mounted on the top of the suspended bracket, a fixed sleeve slidably mounted on the top of the suspended bracket, and an movable cavity for the laser generator to pass through the top of the lateral end of the L-shaped plate.

[0013] As an improved technical solution, the top of the two support legs of the suspended bracket is fixed with a first guide rail, and the front and rear ends of the bottom of the L-shaped plate are equipped with a first slider that slides on the first guide rail. A first electric telescopic rod for pushing the L-shaped plate to move horizontally is installed on one side of the top of the suspended bracket.

[0014] As an improved technical solution, a second guide rail is installed on one side of the top of the horizontal end of the L-shaped plate, and a second slider that slides on the side of the fixed sleeve near the second guide rail is installed thereon. A linear motor that drives the fixed sleeve to move back and forth is installed on the other side of the top of the horizontal end of the L-shaped plate, and the movable end of the linear motor is fixedly connected to the fixed sleeve.

[0015] As an improved technical solution, a negative pressure port is provided on the end face of the processing chamber away from the ultraviolet laser isolation door panel, a vacuum pump is installed on the top of the processing chamber, a negative pressure pipe is fixed to the negative pressure inlet of the vacuum pump, and the end of the negative pressure pipe away from the vacuum pump is fixed at the position of the processing chamber directly opposite the negative pressure port.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the pressure block enters the transverse end of the L-shaped cavity for locking, locking the gun cap body on the top of the truncated disc. This is used to limit the gun cap body from shifting during processing, ensuring the accuracy of the installation position. By locking the pressure block to the transverse end of the L-shaped cavity, the gun cap body cannot fall off the truncated disc when it is in a rotating or tilting state, improving stability and facilitating quick assembly and disassembly of the gun cap body.

[0018] 2. This utility model uses a clamp to lock the cannon cap body, maintaining its processing stability during angle adjustment. At the same time, the laser head can move laterally, backward, left, and right, and with the 360-degree dead-angle adjustment of the cannon cap body's lateral and longitudinal angles, it can flexibly and accurately guide the laser beam to any position on the surface of the cannon cap body. The multi-axis coordinated motion completely eliminates processing dead angles, ensuring that the entire outer surface of the cannon cap can obtain uniform and sufficient laser crushing treatment. At the same time, it eliminates the tedious steps of repeatedly stopping the machine and manually adjusting the cannon cap angle, significantly shortening the processing cycle and greatly improving production efficiency.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0026] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a carbon fiber cannon cap manufacturing device. This carbon fiber cannon cap manufacturing device includes a processing chamber 1. An ultraviolet laser isolation door panel 6 is slidably installed at the access port of the processing chamber 1. An angle adjustment component 2 is installed at the bottom inside the processing chamber 1. The fixed end of the angle adjustment component 2 is detachably installed with a cannon cap body 3. L-shaped cavities 9 are opened on both sides of the periphery of the cannon cap body 3.

[0027] The angle adjustment component 2 includes a rotary table 21 installed inside the processing chamber 1. A rotary disk 29 is longitudinally mounted on the rotating end of the rotary table 21. A servo motor 210 is installed at the center of the top of the rotary disk 29. The drive end of the servo motor 210 is fixedly connected to a frustum 25. The cannon cap body 3 is detachably mounted on the top of the frustum 25.

[0028] A displacement assembly 4 is installed in the upper part of the processing chamber 1. A laser generator 5 with a carbonization catalyst is fixed to the movable end of the displacement assembly 4. A laser head 10 is installed at the working end of the laser generator 5.

[0029] A rotating seat 22 is fixed to the top of the rotating end of the rotary table 21. A dual-axis motor 23 is installed in the middle of the top of the rotating seat 22. The two drive ends of the dual-axis motor 23 are fixedly connected to rotating blocks 24, and the rotating blocks 24 are welded to the bottom of the rotary disk 29. The drive ends of the dual-axis motor 23 are rotatably mounted on the top of the rotating seat 22 through bearings for support.

[0030] Both sides of the top of the frustum 25 are fixed with positioning blocks 26 that are adapted to the vertical end of the L-shaped cavity 9. The positioning blocks 26 and the vertical end of the L-shaped cavity 9 are engaged to limit the angle of the cannon cap body 3 placed on the frustum 25, thereby achieving self-alignment of the pressure block 27 with the horizontal end of the L-shaped cavity 9. This facilitates the accurate insertion of the pressure block 27 into the horizontal end of the L-shaped cavity 9, making it convenient to quickly and accurately install the cannon cap body 3 on the top of the frustum 25. The two sides of the top of the frustum 25 are equipped with second electric telescopic rods 28 in a back-to-back state. The movable end of 28 is equipped with a pressure block 27 that engages with the transverse end of the L-shaped cavity 9. The two second electric telescopic rods 28 extend, allowing the pressure block 27 to enter the transverse end of the L-shaped cavity 9 for engagement, thus securing the gun cap body 3 to the top of the frustum 25. This is used to limit the gun cap body 3 from shifting during processing, ensuring the accuracy of the installation position. Furthermore, the engagement of the pressure block 27 with the transverse end of the L-shaped cavity 9 prevents the gun cap body 3 from falling off the frustum 25 when it is in a rotating or tilting state, improving stability and facilitating quick assembly and disassembly of the gun cap body 3.

[0031] During use, the clamps lock the cannon cap body 3 to maintain processing stability during angle adjustment. At the same time, the laser head 10 can move laterally, forward, backward, left, and right, and with the 360-degree adjustment of the lateral and longitudinal angles of the cannon cap body 3, it can flexibly and accurately guide the laser beam to any position on the surface of the cannon cap body 3. The multi-axis coordinated motion completely eliminates processing dead angles, ensuring that the entire outer surface of the cannon cap can obtain uniform and sufficient laser crushing treatment. At the same time, there is no need for the tedious steps of repeatedly stopping the machine and manually adjusting the angle of the cannon cap, which significantly shortens the processing cycle and greatly improves production efficiency. Example 2

[0032] Reference Figures 1-2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the displacement component 4 includes a suspended bracket 41 fixed inside the processing chamber 1. An L-shaped plate 42 is slidably installed on the top of the suspended bracket 41. A fixed sleeve 45 is slidably installed on the top of the suspended bracket 41, and the laser generator 5 is fixed inside the fixed sleeve 45. An active cavity 43 is opened at the top of the lateral end of the L-shaped plate 42 for the laser generator 5 to pass through.

[0033] The top of the two legs of the suspended bracket 41 is fixed with a first guide rail. The front and rear ends of the bottom of the L-shaped plate 42 are equipped with first sliders that slide on the first guide rail. A first electric telescopic rod 44 for pushing the L-shaped plate 42 to move is installed on one side of the top of the suspended bracket 41, and the movable end of the first electric telescopic rod 44 is connected to the vertical end of the L-shaped plate 42.

[0034] A second guide rail is installed on one side of the top of the horizontal end of the L-shaped plate 42. A second slider that slides on the side of the fixed sleeve 45 near the second guide rail is installed on the other side of the top of the horizontal end of the L-shaped plate 42. A linear motor 46 that drives the fixed sleeve 45 to move back and forth is installed on the other side of the top of the horizontal end of the L-shaped plate 42, and the movable end of the linear motor 46 is fixedly connected to the fixed sleeve 45.

[0035] A negative pressure port is provided on one end of the processing chamber 1 away from the ultraviolet laser isolation door panel 6. A vacuum pump 7 is installed on the top of the processing chamber 1. A negative pressure pipe 8 is fixed to the negative pressure inlet of the vacuum pump 7, and the end of the negative pressure pipe 8 away from the vacuum pump 7 is fixed at the position of the processing chamber 1 directly opposite the negative pressure port. When the vacuum pump 7 is turned on, the interior of the processing chamber 1 is evacuated through the negative pressure pipe 8. The vacuum environment isolates oxygen, ensuring that the laser energy is used entirely for the directional generation of the carbonized fiber structure of the material, avoiding performance degradation caused by high-temperature oxidation, and improving the carbonization quality.

[0036] During use, the extension and retraction of the first electric telescopic rod 44 can push the L-shaped plate 42 to move laterally, adjusting the position of the laser head 10 laterally left and right. The linear motor 46 drives the fixed sleeve 45 to move laterally back and forth, thereby driving the laser head 10 to adjust laterally back and forth. In other words, the laser head 10 can be finely adjusted laterally left, right and forward. The position of the laser head 10 can be adjusted so that it can break the outer wall of the cannon cap body 3 linearly, further increasing the contact area with the cannon cap body 3 and improving the comprehensiveness and uniformity of the strike.

[0037] The remaining structure is the same as that in Example 1.

[0038] Based on embodiments 1-2, the working principle of this utility model is as follows: The protruding end of the frustum plate 25 is adapted to the inner cavity of the cannon cap body 3. When the cannon cap body 3 is positioned on the frustum plate 25, the two L-shaped cavities 9 on both sides are aligned with the two positioning blocks 26 on both sides. Then, the cannon cap body 3 is placed on the top of the frustum plate 25. The two second electric telescopic rods 28 extend, so that the pressure block 27 enters the transverse end of the L-shaped cavity 9 for locking, thus locking the cannon cap body 3 on the top of the frustum plate 25.

[0039] After the cannon cap body 3 is installed on the truncated disc 25, the ultraviolet laser isolation door 6 is closed, and the vacuum pump 7 is turned on to evacuate the interior of the processing chamber 1 through the negative pressure pipe 8.

[0040] The laser generator 5 strikes the outer wall of the cannon cap body 3 through the laser head 10, breaking the surface of the cannon cap body 3 to form a carbonized fiber layer. The rotary table 21 drives the cannon cap body 3 to rotate, and the adjustment of the lateral angle of the cannon cap body 3 is used to adjust the different contact points between the cannon cap body 3 and the laser head 10.

[0041] Furthermore, the dual-axis motor 23 drives the rotating block 24 to rotate longitudinally, which adjusts the longitudinal angle of the cannon cap body 3 and laser-breaks the peripheral surface of the cannon cap body 3. Subsequently, the servo motor 210 drives the cannon cap body 3, which is placed at a longitudinal angle, to rotate, further expanding the contact area between the laser head 10 and the cannon cap body 3.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
