Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment technology for amorphous and nanocrystalline magnetic cores, and specifically to a support auxiliary device for heat treatment of amorphous and nanocrystalline magnetic cores. Background Technology
[0002] In the heat treatment process of amorphous and nanocrystalline magnetic cores, the cores shrink during heat treatment. Without a supporting shaft, the cores may deform severely. If a fixed shaft is used, the core will shrink and become tightly bound to the shaft after heat treatment, making demolding impossible. Furthermore, the immense binding force will degrade the core's performance. Therefore, a separate shaft is needed to mitigate the effects of core shrinkage.
[0003] However, existing support devices composed of separate shaft cores have many shortcomings in practical applications. Traditional support structures are mostly rigid designs, which are difficult to adapt to the inner edge shapes of amorphous and nanocrystalline magnetic cores of different sizes, resulting in uneven contact or insufficient support force, thereby affecting heat treatment effect and product quality.
[0004] Furthermore, existing equipment is complex to operate during installation and adjustment, making rapid adaptation impossible and reducing production efficiency. Additionally, during heat treatment, the expansion or contraction of materials due to temperature changes can cause additional stress on amorphous or nanocrystalline magnetic cores due to rigid supports, potentially leading to surface damage or internal structural failure.
[0005] On the other hand, while existing elastic support structures can alleviate the above problems to some extent, their designs often lack precise limiting and guiding functions, which makes the support components prone to displacement or instability when subjected to force, further affecting the support effect.
[0006] In addition, the component connection methods of existing devices are usually relatively simple, which makes it difficult to meet the requirements of high-intensity and high-stability use, and they are prone to loosening or wear during long-term use, increasing maintenance costs and safety hazards.
[0007] Therefore, there is an urgent need for a support auxiliary device that can take into account elastic support, precise positioning and convenient operation, so as to solve the problems of uneven support, poor stability and insufficient adaptability in the existing technology, thereby improving the overall efficiency and quality of the heat treatment process of amorphous and nanocrystalline magnetic cores. Utility Model Content
[0008] This invention addresses the problem of core deformation in amorphous and nanocrystalline magnetic cores during heat treatment due to a lack of effective support in existing technologies. It proposes a support auxiliary device for the heat treatment of amorphous and nanocrystalline magnetic cores. Through the coordinated design of an elastic support structure, an arc-shaped contact plate, and a baffle, the device achieves uniform support and stable positioning of the inner edge surface of the amorphous and nanocrystalline magnetic core, thereby significantly improving the reliability and efficiency of the heat treatment process.
[0009] This invention provides a support auxiliary device for heat treatment of amorphous and nanocrystalline magnetic cores, comprising an elastic support structure, arc-shaped contact plates, and a baffle. Two arc-shaped contact plates are respectively disposed on two symmetrical sides of the elastic support structure, with the outer edge of each arc-shaped contact plate in contact with the inner edge of the amorphous or nanocrystalline magnetic core to be heat-treated. The elastic support structure is located between the two arc-shaped contact plates, ensuring that the outer edge of each arc-shaped contact plate remains in close contact with the inner edge of the amorphous or nanocrystalline magnetic core. Furthermore, the baffle is disposed on the side of the elastic support structure that contacts one of the arc-shaped contact plates, providing auxiliary restraint to the elastic support structure.
[0010] Furthermore, the elastic support structure includes a first support assembly and a second support assembly, which are fixedly connected. Each support assembly includes a fixed component and a support component, wherein there are two support components, symmetrically arranged at both ends of the fixed component. The opposite ends of the two support components contact the inner edge surface of the arc-shaped contact plate to achieve elastic support for the arc-shaped contact plate.
[0011] Specifically, the support component is preferably arc-shaped to ensure good contact with the inner edge of the arc-shaped contact plate, thereby improving the uniformity of support. Furthermore, the baffle plate has a sliding groove, into which the support component is inserted and can slide to accommodate amorphous and nanocrystalline magnetic cores of different sizes. Through the design of the sliding groove, the support component can move within a certain range, thus meeting the support requirements of various magnetic core specifications.
[0012] Furthermore, the fixing components are connected by a fixing part, which is implemented in two ways: The first way is to use a combination of a limiting block, a limiting plate, and a limiting bolt. Specifically, the fixing component has a limiting groove, and the limiting block is U-shaped and can be inserted into two limiting grooves simultaneously. The limiting plate is fixedly connected to the limiting block by the limiting bolt, closing the U-shaped opening of the limiting block. To improve the tightness of the fit, the sidewall of the limiting groove has rounded corners, making the contact between the limiting block and the fixing component tighter.
[0013] The second method uses a combination of fixing screws and nuts. The fixing component has a fixing hole, and the fixing screw is inserted into the fixing hole and threadedly connected to the fixing screw via the nut, thus securing the two fixing components together. Both of these fixing methods achieve a firm connection between the fixing components while facilitating disassembly and maintenance.
[0014] Specifically, a gap exists between the corresponding ends of the two arc-shaped contact plates to avoid interference. Furthermore, the fixing component is an arc tangent to the supporting component, further optimizing the overall structural compactness and stability. Through this design, the elastic support structure not only provides stable support force but also adaptively adjusts to changes in the dimensions of amorphous and nanocrystalline magnetic cores, thereby ensuring consistent support performance.
[0015] Furthermore, the outer edge of the arc-shaped contact plate is precision-machined to achieve a surface roughness of Ra0.8 or less, thereby reducing friction with the inner edge of the amorphous or nanocrystalline magnetic core and preventing surface damage caused by friction. In addition, the arc-shaped contact plate is made of high-temperature resistant alloy steel to withstand the high-temperature environment during heat treatment. The supporting components are also made of alloy materials with high elasticity and high-temperature resistance to ensure that fatigue deformation or performance degradation will not occur during long-term use.
[0016] Furthermore, the inner wall of the sliding groove of the baffle is hardened to improve its wear resistance. The width of the sliding groove is slightly larger than the width of the supporting component to ensure that the supporting component can move freely within the sliding groove, while avoiding wobbling caused by excessive gaps. The thickness of the baffle is designed according to actual usage requirements, typically between 3mm and 10mm, to balance strength and lightweight requirements. The beneficial effects of this utility model are: First, through the design of the elastic support structure, the outer edge of the arc-shaped contact plate is always in close contact with the inner edge of the amorphous or nanocrystalline magnetic core to be heat-treated, thereby achieving uniform support for the magnetic core.
[0017] Secondly, the sliding groove on the baffle allows the support components to move along the sliding groove, which can accommodate amorphous and nanocrystalline magnetic cores of different sizes, significantly improving the applicability of the device.
[0018] Finally, a variety of fixing methods, such as limit blocks and fixing screws, are used to achieve a firm connection between the fixing components, ensuring the stability of the device during use. Attached Figure Description

Detailed Implementation
[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0021] Example 1
[0022] This utility model provides a support auxiliary device for heat treatment of amorphous and nanocrystalline magnetic cores, combined with an attached... Figure 1 To be continued Figure 7 The specific embodiments of this utility model are described in detail below. The device includes an elastic support structure, an arc-shaped contact plate 1, and a baffle 2. The coordinated design of these components achieves uniform support and stable positioning of the inner edge surface of the amorphous or nanocrystalline magnetic core 12. The elastic support structure consists of a first support component and a second support component, which are fixedly connected and work together to ensure that the arc-shaped contact plate 1 maintains close contact with the inner edge surface of the magnetic core 12 to be heat-treated. The baffle 2 is located on one side of the elastic support structure and has a sliding groove 5. The design of the sliding groove 5 allows the support component 4 to move along the groove, thereby accommodating amorphous or nanocrystalline magnetic cores 12 of different sizes.
[0023] The first and second support components of the elastic support structure both include a fixing component 3 and a support component 4, wherein there are two support components 4 symmetrically arranged at both ends of the fixing component 3. The opposite ends of the support components 4 are in contact with the inner edge surface of the arc-shaped contact plate 1. This design allows the support force to be evenly distributed on the arc-shaped contact plate 1 and then transmitted to the inner edge surface of the amorphous or nanocrystalline magnetic core 12.
[0024] The support component 4 is preferably arc-shaped, and its shape fits well with the inner edge of the arc-shaped contact plate 1, ensuring a more uniform and stable support effect. In actual operation, when the amorphous or nanocrystalline magnetic core 12 is fitted into the device, the support component 4 will expand to both sides due to elastic deformation, so that the outer edge of the arc-shaped contact plate 1 always remains in contact with the inner edge of the magnetic core 12. This process is completed through the adaptive adjustment of the elastic support structure, which solves the problem of uneven heating or deformation of the amorphous or nanocrystalline magnetic core 12 due to lack of effective support during heat treatment.
[0025] The sliding groove 5 on the baffle 2 provides space for the support component 4 to move. The width of the sliding groove 5 is slightly larger than the width of the support component 4 to ensure that the support component 4 can slide freely in the groove, while avoiding wobbling due to excessive gap.
[0026] The inner wall of the sliding groove 5 is hardened, which improves its wear resistance and extends the service life of the device. In practical applications, when it is necessary to adjust the position of the support component 4 to accommodate amorphous or nanocrystalline magnetic cores 12 of different sizes, the operator only needs to push the support component 4 along the sliding groove 5. This design not only simplifies the operation steps but also significantly expands the applicability of the device.
[0027] The connection method between the fixing components 3 is one of the important technical features of this utility model. The fixing part adopts two different implementation methods. The first method is shown in the attached figure. Figure 3 As shown, the fixing part includes a limiting block 6, a limiting plate 7, and a limiting bolt 8. A limiting groove 9 is formed on the fixing component 3, and the limiting block 6 is U-shaped and can be simultaneously inserted into two limiting grooves 9. The limiting plate 7 is fixedly connected to the limiting block 6 by the limiting bolt 8, closing the U-shaped opening of the limiting block 6. To improve the tightness of the fit, the sidewalls of the limiting grooves 9 are provided with rounded corners, making the contact between the limiting block 6 and the fixing component 3 more secure.
[0028] Example 2
[0029] The second method is shown in the appendix. Figure 4 As shown, the fixing part includes a fixing screw 10 and a nut assembly 11. A fixing hole is provided on the fixing component 3. The fixing screw 10 is inserted into the fixing hole and threadedly connected to the fixing screw 10 via the nut assembly 11, thus achieving a fixed connection between the two fixing components 3. Both fixing methods ensure a secure connection between the fixing components 3 while facilitating disassembly and maintenance.
[0030] Example 3
[0031] Combined with appendix Figure 6Furthermore, the fixed components 3 can also be connected by welding. The advantages of welding connections are a more compact structure and higher stability, making them suitable for scenarios requiring high overall strength of the device. In actual manufacturing, the appropriate welding process must be selected based on specific needs to ensure that the quality and strength of the weld meet the usage requirements.
[0032] The design of the arc-shaped contact plate 1 also reflects the technical innovation of this utility model. (Combined with the attached...) Figure 7 The two arc-shaped contact plates 1 have a gap at their corresponding ends to avoid interference. The outer edge of the arc-shaped contact plate 1 is precision machined to achieve a surface roughness of Ra0.8 or less, reducing friction with the inner edge of the amorphous or nanocrystalline magnetic core 12 and preventing surface damage caused by friction. The arc-shaped contact plate 1 is made of high-temperature resistant alloy steel, capable of withstanding the high-temperature environment during heat treatment. The fixing component 3 is an arc tangent to the supporting component 4, further optimizing the compactness and stability of the overall structure.
[0033] In practical applications, the operation procedure of this device is as follows: S1 inserts the amorphous or nanocrystalline magnetic core 12 to be heat-treated into the device, so that the inner edge of the magnetic core 12 contacts the outer edge of the arc-shaped contact plate 1.
[0034] S2 adjusts the position of the support component 4 according to the size of the amorphous or nanocrystalline magnetic core 12, and pushes the support component 4 to move along the sliding groove 5 until the outer edge of the arc-shaped contact plate 1 is completely in contact with the inner edge of the magnetic core 12.
[0035] S3 checks whether the connection between the fixed parts 3 is secure, ensuring that the device will not loosen during use.
[0036] S4 starts the heat treatment equipment and begins heat treatment of the amorphous and nanocrystalline magnetic core 12. Throughout the heat treatment process, the elastic support structure maintains close contact between the arc-shaped contact plate 1 and the inner edge surface of the magnetic core 12 through the elastic deformation of the support component 4 and the adjustment function of the sliding groove 5, thereby achieving uniform support and stable positioning.
[0037] The beneficial effects of this device are reflected in several aspects.
[0038] First, the design of the elastic support structure ensures that the outer edge of the arc-shaped contact plate 1 is always in close contact with the inner edge of the amorphous or nanocrystalline magnetic core 12, thus solving the problem of uneven heating or deformation of the magnetic core 12 due to lack of effective support during heat treatment.
[0039] Secondly, the sliding groove 5 on the baffle 2 allows the support component 4 to move along the groove, which can accommodate amorphous and nanocrystalline magnetic cores 12 of different sizes, significantly improving the applicability of the device.
[0040] Furthermore, a robust connection between the fixing components 3 is achieved through multiple fixing methods, ensuring the stability of the device during use.
