Description

Technical Field

[0001] This utility model relates to the field of material manufacturing equipment technology, and in particular to an adjustable nozzle for the production of nanocrystalline ribbon. Background Technology

[0002] Amorphous and nanocrystalline alloy strips have been widely used in electronics, power, aerospace, and other fields due to their excellent soft magnetic properties, high strength, high hardness, and good corrosion resistance. The mainstream manufacturing method is the single-roll rapid quenching method. The core of this method is to spray molten alloy liquid through a precision nozzle at extremely high speed onto the surface of a high-speed rotating cooling roller, causing it to solidify rapidly in a very short time. In this process, the nozzle, as a key component that directly contacts the high-temperature alloy liquid and uniformly sprays it into shape, directly affects the forming quality and production efficiency of the strip due to its rational structural design.

[0003] In current production practices, nozzles are typically made of high-temperature resistant and corrosion-resistant ceramic or alloy materials. Their structure generally includes a nozzle cup to hold the molten alloy and a nozzle assembly with a narrow, elongated nozzle orifice. However, during prolonged production, impurities or incompletely melted particles in the high-temperature molten alloy can easily accumulate and clog the narrow nozzle orifice, leading to defects such as discontinuous or uneven thickness of the ejected strip, and in severe cases, even production interruptions. Therefore, regular disassembly and cleaning of the nozzles are necessary. Currently, most nozzle assemblies use bolted flange connections or high-temperature sintering for integral molding. The former involves cumbersome disassembly and assembly, requiring specialized tools and is time-consuming and labor-intensive; the latter cannot be disassembled and cleaned, and once clogged or worn, the entire assembly must be scrapped, resulting in significant cost waste and reduced overall production line efficiency.

[0004] Furthermore, to meet market demand for alloy strips of varying widths, traditional processes typically require the preparation of multiple nozzle components with different nozzle widths. When changing product types, the entire nozzle component must be replaced after a production shutdown. This not only increases spare parts inventory costs and management complexity but also results in a lengthy replacement process, leading to excessively long adjustment times for production lines when switching specifications. Consequently, production flexibility is poor, making it difficult to adapt to modern production models that require small-batch, multi-specification production.

[0005] Therefore, this utility model proposes an ultra-thin spray nozzle to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an adjustable nozzle for the production of nanocrystalline ribbons, aiming to improve the problems of complex connection structure, inconvenient disassembly, cleaning and maintenance, fixed nozzle width and poor production flexibility of existing ultra-thin ribbon spraying nozzles.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An ultra-thin ribbon spray nozzle includes: a nozzle cup, a nozzle element; and a connecting assembly for fixing the nozzle element to the nozzle cup.

[0008] The connecting assembly includes a threaded sleeve that is threadedly connected to the nozzle cup and a clamping block disposed between the threaded sleeve and the nozzle component. The threaded sleeve has a tapered inner wall, the clamping block has stripes, and the outer side of the nozzle component has an annular groove that engages with the stripes.

[0009] Furthermore, the threaded sleeve presses the clamping block through its conical inner wall, causing the stripes on the clamping block to engage with the annular groove of the nozzle component, thereby securely mounting the nozzle component onto the nozzle cup.

[0010] Preferably, the ultra-thin strip spray nozzle further includes an adjustment component disposed on the nozzle component, the adjustment component including a stop block slidably disposed on the nozzle component to block part of the spray nozzle opening.

[0011] Preferably, the nozzle component is provided with a groove for the stop block to slide.

[0012] Preferably, the nozzle component has a threaded hole, the stop block has a threaded groove for the fastening screw to pass through, and the adjusting assembly further includes a fastening screw that passes through the threaded groove and is threadedly connected to the threaded hole.

[0013] Preferably, the end of the fastening screw is provided with a knob.

[0014] Preferably, the threaded groove is a through groove that extends along the sliding direction of the slide groove.

[0015] Preferably, the end of the nozzle component that is inserted into the nozzle cup has a protrusion, and the inner wall of the nozzle cup has a snap-fit ​​structure that cooperates with the protrusion to prevent the nozzle component from rotating relative to the nozzle cup.

[0016] Preferably, the clamping block is a radially retractable structure along the nozzle component.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a connecting component consisting of a threaded sleeve, a clamping block, stripes, and annular grooves, the conical inner wall of the threaded sleeve squeezes the clamping block when tightened, so that the clamping block firmly engages and holds the nozzle component. This solves the problems of complex nozzle connection structure, reliance on tools, and difficulty in disassembly, assembly, cleaning, and maintenance in the prior art. It achieves the technical effect of a stable and reliable connection, and enables quick, tool-free disassembly and assembly, which greatly facilitates the daily maintenance of the equipment.

[0018] 2. In this utility model, by setting a groove on the nozzle component and installing a slidable stop block in the groove, and then using a fastening screw with a knob to pass through the threaded groove on the stop block for locking and fixing, the problem of fixed nozzle outlet width and inability to flexibly adapt to the production needs of different specifications of strip material in the prior art is solved. The technical effect of being able to conveniently and accurately adjust the effective width of the spray nozzle is achieved, thereby flexibly controlling the width of the finished strip material.

[0019] 3. In this utility model, by integrating the tool-free disassembly and assembly connecting component with the sliding adjustable adjustment component into an integrated design, the problems of single function and complex operation and maintenance of the nozzle structure in the prior art are solved. This achieves a comprehensive technical effect of compact structure, high integration, convenient operation, and multi-purpose use, which significantly improves production flexibility and equipment maintenance efficiency.

[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 refer to Figures 1 to 6 This utility model provides an ultra-thin strip spray nozzle, which aims to solve the problems of inconvenient disassembly and assembly, difficult cleaning and maintenance, and inflexible production width adjustment in the prior art.

[0024] like Figures 1 to 3 As shown, the ultra-thin strip spray nozzle includes a nozzle cup 1 and a nozzle component 2. The main body of the nozzle cup 1 is a hollow structure for containing the alloy liquid, and a slit 4 is provided inside one end of it. The nozzle component 2 is provided with a spray nozzle 5 that communicates with the slit 4. The nozzle component 2 is detachably installed inside the nozzle cup 1.

[0025] In this embodiment, one end of the nozzle component 2 is installed inside the nozzle cup 1 by plugging it in. To ensure that the leak slit 4 and the spray nozzle 5 can be accurately aligned after installation, a protrusion is fixedly connected to the outer wall of the end of the nozzle component 2 that is inserted into the nozzle cup 1. The inner wall of the nozzle cup 1 is provided with a corresponding snap-fit ​​structure that cooperates with the protrusion. Through the cooperation between the protrusion and the snap-fit ​​structure, the nozzle component 2 is circumferentially limited to prevent the nozzle component 2 from rotating relative to the nozzle cup 1.

[0026] In this embodiment, the nozzle cup 1 and the nozzle component 2 are connected by a connecting component 3 to achieve a stable and quick-disassembly connection. At the same time, the nozzle component 2 is also provided with an adjustment component 6 for changing the effective width of the spray nozzle 5.

[0027] The structure and connection relationship of connecting component 3 and adjusting component 6 are described in detail below: like Figures 2 to 6 As shown, the connecting assembly 3 includes a threaded sleeve 301 and a clamping block 302. The threaded sleeve 301 is fitted on the outside of the nozzle component 2 and is threadedly connected to the external thread at the end of the nozzle cup 1 through its internal thread. The end of the threaded sleeve 301 away from the nozzle cup 1 has an inwardly tapered inner wall. The clamping block 302 is disposed between the tapered inner wall of the threaded sleeve 301 and the outer wall of the nozzle component 2. The clamping block 302 is a radially retractable structure along the nozzle component 2. Several circumferentially distributed stripes 303 are fixedly connected to its inner wall. Correspondingly, annular grooves 304 are provided on the outer wall of the nozzle component 2 to engage with the stripes 303. When the threaded sleeve 301 is tightened onto the nozzle cup 1, its tapered inner wall will squeeze the clamping block 302 to cause radial contraction, thereby tightly clamping the nozzle component 2. At the same time, the stripes 303 on the clamping block 302 will also be firmly engaged in the annular grooves 304. In this way, the nozzle component 2 is fixed axially and circumferentially on the nozzle cup 1.

[0028] like Figure 5 and Figure 6As shown, the adjusting component 6 is used to adjust the width of the nanocrystalline ribbon. It includes a stop 601, a fastening screw 604, and a knob 603. A groove 602 for the stop 601 to slide on the end face of the nozzle component 2 is provided. The stop 601 is slidably installed in the groove 602. A through groove extending along the sliding direction of the groove 602 is provided on the stop 601 as a threaded groove 606. The nozzle component 2 is provided with a threaded hole 605 that mates with the threaded groove 606. The nail 604 passes through the threaded groove 606 and is threaded into the threaded hole 605. It is used to fix the stop 601 at any position in the slide 602. The head of the fastening screw 604 is fixedly connected to the knob 603 for easy manual rotation. By loosening the fastening screw 604, the stop 601 can be moved along the slide 602, so that the front end of the stop 601 blocks part of the spray nozzle 5, thereby changing the spray width of the spray nozzle 5. After adjusting to the appropriate position, tighten the fastening screw 604 to complete the fixation.

[0029] As a preferred embodiment, in order to ensure the alignment accuracy of the slit 4 and the spray nozzle 5 during the installation process, a protrusion is fixedly connected to the outer wall of the end of the nozzle component 2 that is inserted into the nozzle cup 1, and a corresponding snap-fit ​​structure is provided on the inner wall of the nozzle cup 1 to cooperate with the protrusion. Through the cooperation between the protrusion and the snap-fit ​​structure, the nozzle component 2 is circumferentially limited to prevent the nozzle component 2 from rotating relative to the nozzle cup 1.

[0030] Furthermore, to achieve a reliable clamping effect, the clamping block 302 is a radially retractable elastic structure along the nozzle 2, such as an open ring composed of one or more arc-shaped blocks. When subjected to radial pressure from the conical inner wall of the threaded sleeve 301, the clamping block 302 can retract inward and uniformly clamp the outer wall of the nozzle 2.

[0031] As a further optimization of the adjustment component 6, the threaded groove 606 on the stop 601 is a through groove extending along the sliding direction of the slide groove 602. The length of the threaded groove 606 is greater than the diameter of the fastening screw 604, thereby providing the necessary travel space for the sliding adjustment of the stop 601 in the slide groove 602.

[0032] To facilitate tool-free operation, a knob 603 is fixedly connected to the head of the fastening screw 604. The operator can tighten or loosen the fastening screw 604 by directly turning the knob 603, thereby achieving quick fixing or unlocking of the stop 601 and improving adjustment efficiency.

[0033] Working principle: During assembly, first insert the left end of the nozzle component 2 into the right end of the nozzle cup 1. The protrusion on the left end of the nozzle component 2 will cooperate with the snap-fit ​​structure inside the nozzle cup 1 to prevent the nozzle component 2 from rotating inside the nozzle cup 1, so that the spray nozzle 5 on the nozzle component 2 can be accurately aligned with the gap 4 on the nozzle cup 1. Then, tighten the threaded sleeve 301 on the outside of the nozzle cup 1 from right to left. While tightening the threaded sleeve 301, the conical inner wall on its right side will press the clamping block 302 inward, so that the clamping block 302 tightly clamps the outside of the nozzle component 2. At the same time, the stripe 303 on the clamping block 302 will also be firmly inserted into the annular groove 304 of the nozzle component 2, thus firmly installing the nozzle component 2 on the nozzle cup 1. Disassembly can be performed by reversing the operation. The whole process does not require tools and is convenient and quick.

[0034] When producing nanocrystalline ribbon, the molten alloy is first injected into the nozzle cup 1. The molten alloy is then sprayed onto the cooling roller or substrate through the aligned slots 4 and the spray nozzles 5, thereby quickly solidifying to form nanocrystalline ribbon. When the width of the ribbon needs to be adjusted, the fastening screw 604 is first loosened from the threaded hole 605 by rotating the knob 603. At this time, the stop block 601 can slide freely in the groove 602. Sliding the stop block 601 along the groove 602 will block part of the spray nozzle 5, thereby changing the effective width of the ribbon sprayed out. After adjusting the stop block 601 to the appropriate position, the knob 603 is rotated again to tighten the fastening screw 604 along the threaded groove 606 through which it passes into the threaded hole 605. This will securely position the stop block 601 and complete the adjustment of the width of the nanocrystalline ribbon.

[0035] 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.
