Description

Technical Field

[0001] This utility model relates to the field of nozzle devices, and in particular to a nozzle structure for an amorphous nanocrystalline ribbon. Background Technology

[0002] Amorphous nanocrystalline ribbons are a type of high-performance metallic material widely used in electronics, power, aerospace and other fields. Through special preparation processes, the metallic material exhibits amorphous or nanocrystalline properties in its microstructure, thereby endowing the material with excellent physical and mechanical properties. In the production process of amorphous nanocrystalline ribbons, the nozzle structure is one of the key components, and its performance directly affects the spraying effect of the molten metal and the quality of the final product.

[0003] During operation, the nozzle is generally placed at an angle, and a cooling roller is installed at the output end of the nozzle. This layout is mainly to ensure that the molten metal can quickly contact the surface of the cooling roller after spraying and form a strip, so as to achieve rapid cooling and solidification. Therefore, when installing the nozzle, one end of the nozzle opening needs to be close to the cooling roller to ensure that the molten metal can contact the cooling roller immediately after spraying.

[0004] Currently, traditional nozzle structures require manual alignment or centering during installation, followed by the use of high-temperature adhesive for fixation. Inadequate adhesion can lead to nozzle detachment and damage. Furthermore, the nozzle orifice may be installed backwards during the bonding process, affecting the spraying of molten metal.

[0005] Therefore, it is necessary to propose a nozzle structure for amorphous nanocrystalline ribbons to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a nozzle structure for amorphous and nanocrystalline ribbons to solve the problems mentioned in the background art, such as nozzle detachment and nozzle inversion during bonding due to imperfect high-temperature adhesive fixation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a nozzle structure for an amorphous nanocrystalline ribbon, comprising a nozzle cup and a nozzle component;

[0008] The nozzle component engages with the nozzle cup;

[0009] The nozzle cup has a hollow interior, and limiters are fixedly installed on both the front and rear surfaces of the nozzle cup.

[0010] A mating groove is provided on the front surface of the nozzle cup and below the limiting member, and the mating groove penetrates the nozzle cup.

[0011] A first groove is formed on the bottom surface of the nozzle cup near one side, and a second groove is formed on the bottom surface of the nozzle cup near the other side.

[0012] Preferably, a mating strip is fixedly installed on both sides of the nozzle component and near the top, and the mating strip corresponds to the mating groove.

[0013] Preferably, a first retaining strip is fixedly installed on one side surface of the nozzle component and below the mating strip, and a second retaining strip is fixedly installed on the other side surface of the nozzle component and below the mating strip;

[0014] The first card is C-shaped, and the second card is T-shaped.

[0015] Preferably, the first groove corresponds to the first card strip, and the second groove corresponds to the second card strip.

[0016] Preferably, the nozzle component has a hollow interior, and a groove is formed on the upper surface of the nozzle component near one side, the groove being connected to the interior of the nozzle component.

[0017] Preferably, the nozzle has a nozzle opening at its bottom and directly below the trough.

[0018] Preferably, the limiting member has a limiting hole, a telescopic plate is movably installed inside the limiting member, and a fastening bolt is spirally installed on the telescopic plate.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. The limiting component and connecting strip in this utility model adopt a snap-fit ​​fixing method instead of high-temperature adhesive bonding, which can quickly position and install without complicated manual alignment or centering operations, greatly improving installation efficiency. The stable nozzle structure can withstand the impact and vibration generated during molten metal spraying, ensuring the reliability of the nozzle in long-term use. The mechanical fixing method facilitates the disassembly and maintenance of the nozzle, reduces equipment downtime and maintenance costs, and avoids the problem of nozzle falling off due to unsatisfactory high-temperature adhesive bonding effect.

[0021] 2. The first and second locking strips in this utility model, through their unique locking strip and groove structure, ensure that the nozzle component and the nozzle cup can only be installed in the correct way, avoiding the phenomenon of the nozzle opening being installed backwards. This design not only improves the accuracy of installation, but also reduces production accidents and equipment damage caused by installation errors. At the same time, by optimizing the nozzle structure, the turbulence phenomenon of molten metal in the nozzle is reduced, further improving the quality and consistency of the strip production.

[0027] This invention provides a nozzle structure for amorphous nanocrystalline ribbons. Please refer to the attached document. Figure 1 As shown.

[0028] The nozzle includes a nozzle cup 1 and a nozzle component 2, which engage with the nozzle cup 1. The nozzle cup 1 and nozzle component 2 are the core components of this nozzle structure. They are tightly connected together by engaging, forming a whole, which ensures the stability and reliability of the nozzle structure and provides a solid foundation for the spraying of molten metal.

[0029] Specifically, the nozzle cup 1 has a hollow interior design. Limiting components 3 are fixedly installed on both the front and rear surfaces of the nozzle cup 1. Limiting holes 301 are provided on the limiting components 3. A telescopic plate 302 is movably installed inside the limiting components 3. Fastening bolts 303 are screwed onto the telescopic plate 302. The setting of the limiting components 3, limiting holes 301, telescopic plate 302 and fastening bolts 303 can precisely control the position and attitude of the nozzle cup 1, ensuring the positional accuracy of the nozzle cup 1 during installation and use, thereby ensuring the uniform spraying of molten metal and improving product quality.

[0030] Please see the appendix Figure 2 As shown.

[0031] A docking groove 103 is provided on the front surface of the nozzle cup 1 and below the limiting member 3. The docking groove 103 penetrates the nozzle cup 1 and provides a connection channel for the docking of the nozzle component 2, so that the nozzle component 2 can accurately dock with the nozzle cup 1, ensuring the stability and reliability of the nozzle structure and avoiding problems such as metal liquid leakage or uneven spraying caused by inaccurate docking.

[0032] Specifically, a first groove 101 is provided on the bottom surface of the nozzle cup 1 near one side, and a second groove 102 is provided on the bottom surface of the nozzle cup 1 near the other side. The first groove 101 and the second groove 102 provide positioning and installation space for the nozzle component 2, so that the nozzle component 2 can be accurately engaged with the nozzle cup 1, further enhancing the stability and reliability of the nozzle structure, and also facilitating the installation and disassembly of the nozzle component 2, reducing equipment downtime.

[0033] Specifically, a mating strip 203 is fixedly installed on both sides of the nozzle component 2 near the top, and the mating strip 203 corresponds to the mating groove 103.

[0034] Specifically, a first retaining strip 201 is fixedly installed on one side surface of the nozzle component 2 and below the mating strip 203, and a second retaining strip 202 is fixedly installed on the other side surface of the nozzle component 2 and below the mating strip 203. This enhances the stability and reliability of the nozzle structure and avoids problems such as nozzle loosening or falling off due to insecure engagement.

[0035] Please see the appendix Figure 2 - Appendix Figure 3 As shown.

[0036] The nozzle component 2 has a hollow interior. A groove 204 is provided on the upper surface of the nozzle component 2 near one side. The groove 204 is connected to the interior of the nozzle component 2. The hollow design of the nozzle component 2 provides space for the flow of molten metal inside, while the groove 204 provides a channel for the spraying of molten metal, so that the molten metal can be smoothly sprayed out from the interior of the nozzle component 2, ensuring the normal operation of the nozzle and the uniform spraying of molten metal.

[0037] Specifically, a nozzle orifice 205 is provided at the bottom of the nozzle component 2 and directly below the trough 204. The nozzle orifice 205 is the final outlet for the molten metal injection.

[0038] Specifically, the first locking strip 201 is C-shaped and the second locking strip 202 is T-shaped. The different shapes of the first locking strip 201 and the second locking strip 202 enable the nozzle component 2 to quickly and accurately engage with the nozzle cup 1, improving installation efficiency and stability. If the installation is incorrect, the engagement will fail, ensuring the accuracy of the installation process. At the same time, it can quickly align the trough 204 and the nozzle orifice 205 on the same vertical plane, thereby ensuring the smooth flow of molten metal in the nozzle and avoiding turbulence caused by incorrect installation, thus improving product quality and production stability.

[0039] Specifically, the first groove 101 corresponds to the first locking strip 201, and the second groove 102 corresponds to the second locking strip 202.

[0040] Please see the appendix Figure 4 As shown.

[0041] The groove 204 and the nozzle 205 are located on the same vertical plane. This design ensures that the molten metal flows smoothly from the groove 204 into the nozzle 205 and is sprayed out in a uniform and stable manner, thereby ensuring the quality and efficiency of the strip making process and improving the quality and performance of the product.

[0042] In use, the mating strip 203 of the nozzle component 2 is aligned with the mating groove 103 on the front surface of the nozzle cup 1 and inserted to allow the nozzle component 2 and the nozzle cup 1 to initially align. At the same time, the first locking strip 201 and the second locking strip 202 of the nozzle component 2 are aligned with the first groove 101 and the second groove 102 on the bottom surface of the nozzle cup 1 and engaged, completing the tight connection between the nozzle component 2 and the nozzle cup 1, forming an integral nozzle structure. The different shapes of the first locking strip 201 and the second locking strip 202 enable the nozzle component 2 to engage quickly and accurately with the nozzle cup 1 without errors during installation. The trough 204 and the nozzle orifice 205 are always kept on the same vertical plane, allowing the molten metal to be sprayed out evenly and stably from the nozzle orifice 205. The sprayed molten metal is rapidly cooled and solidified under the action of the subsequent cooling roller to form an amorphous nanocrystalline ribbon, completing the manufacturing process.
