[0001] The utility model relates to the technical field of NdFeB magnet production equipment, in particular to a layered stacking bracket used for NdFeB magnet production. Background Art
[0002] In the production process of NdFeB magnets, the magnet materials need to go through many complex process steps, including melting, casting, heat treatment, cutting and magnetization. In these steps, especially in the melting and heat treatment stages, the magnet materials need to withstand high temperature treatment and must maintain the stability of their shape and structure. Therefore, it is particularly important to design an effective support and fixing structure.
[0003] In the traditional magnetic steel production method, the size of the magnetic steel material does change to a certain extent after being subjected to high temperature treatment due to the principle of thermal expansion and contraction. When these high-temperature treated magnetic steel materials are stacked on the bracket and then cooled, due to the difference in thermal expansion coefficients between the magnetic steel and the bracket materials, their respective contraction degrees will also be different. This may lead to a gap between the magnetic steel material and the bracket after cooling.
[0004] The presence of this gap may cause a series of problems. First, the gap will affect the stability and integrity of the magnet stack. If the gap is too large, the magnet may shift or fall during subsequent handling or transportation, thus affecting production efficiency and product quality. Utility Model Content

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0026] like Figures 1 to 5 As shown, the utility model describes a layered stacking bracket for the production of NdFeB magnetic steel, comprising a fixed bracket 1 and a placement bracket 2, wherein the placement bracket 2 is arranged on the fixed bracket 1, and the placement bracket 2 is used to hold the NdFeB magnetic steel workpiece 4, and also includes a limit compensation mechanism 3, a plurality of the limit compensation mechanisms 3 are arranged in a matrix on the top of the placement bracket 2, and the limit compensation mechanism 3 is used to limit the displacement of the NdFeB magnetic steel workpiece 4 held in the placement bracket 2; when the NdFeB magnetic steel workpiece 4 is placed on the placement bracket 2, the limit compensation mechanism 3 fixes and limits the NdFeB magnetic steel workpiece 4.
[0027] Specifically, firstly, the combination of the fixed support 1 and the placement bracket 2 provides a stable foundation for the magnetic steel. The arrangement of the placement bracket 2 enables the magnetic steel to be placed neatly and orderly, which is convenient for subsequent operation and processing. Secondly, the NdFeB magnetic steel workpiece 4 placed in the placement bracket 2 is fixed and limited by the limit compensation mechanism 3, so as to avoid the NdFeB magnetic steel workpiece 4 after high-temperature treatment from changing in size due to thermal expansion and contraction, thereby causing the stacked NdFeB magnetic steel workpiece 4 to be displaced or tipped over.
[0028] Further, refer to Figure 2 As shown, the limit compensation mechanism 3 includes a fixing seat 3a and a limit plate 3b, and a plurality of the fixing seats 3a are relatively arranged around the placement bracket 2, and a limit plate 3b is provided on each of the fixing seats 3a. Specifically, when the NdFeB magnetic steel workpiece 4 after high temperature treatment is placed on the placement bracket 2, the limit plate 3b is in close contact with the NdFeB magnetic steel workpiece 4, thereby effectively ensuring that the NdFeB magnetic steel workpiece 4 can be neatly stacked together.
[0029] Further, refer to Figure 3 As shown, the limit compensation mechanism 3 also includes an elastic member 3c, and the elastic member 3c is arranged between the fixed seat 3a and the limit plate 3b. When the size of the NdFeB magnetic steel workpiece 4 placed on the bracket 2 changes after cooling, the elastic member 3c can provide a certain expansion space so that the limit plate 3b can move with the size change of the magnetic steel. In this way, even if the size of the magnetic steel changes, the limit plate 3b can always maintain close contact with the NdFeB magnetic steel workpiece 4 under the action of the elastic member 3c, thereby ensuring the continuity and stability of the limit effect. In addition, the introduction of the elastic member 3c can also absorb the impact force generated by the magnetic steel during transportation or vibration to a certain extent, reducing damage to the bracket and the magnetic steel itself. This makes the entire layered stacking bracket more flexible and adaptable when dealing with various production environments.
[0030] Further, refer to Figure 5 As shown, the limit compensation mechanism 3 also includes an adjustment plate 3d, and the adjustment plate 3d is arranged between the fixed seat 3a and the elastic member 3c. Specifically, by adjusting the position of the adjustment plate 3d, the compression degree of the elastic member 3c can be indirectly changed, thereby realizing accurate control of the position of the limit plate 3b. When it is necessary to increase the clamping force of the limit plate 3b on the NdFeB magnetic steel workpiece 4, the distance between the adjustment plate 3d and the fixed seat 3a can be appropriately increased to make the elastic member 3c more compressed; conversely, when it is necessary to reduce the clamping force, the distance can be reduced. This adjustment method is simple, intuitive, and easy to operate.
[0031] Further, refer to Figure 4 and Figure 5As shown, the limit compensation mechanism 3 also includes an adjustment rod 3f, the outer side of the adjustment rod 3f is provided with an external thread, the fixing seat 3a is provided with an adjustment hole 3a1, the inner wall of the adjustment hole 3a1 is provided with an internal thread that matches the external thread, and one end of the adjustment rod 3f passes through the adjustment hole 3a1 and touches the adjustment plate 3d. Specifically, through the threaded cooperation between the external thread of the adjustment rod 3f and the internal thread of the adjustment hole 3a1, it is ensured that the adjustment rod 3f can stably move in the adjustment hole 3a1 when rotating without shaking or falling off. By passing one end of the adjustment rod 3f through the adjustment hole 3a1 and touching the adjustment plate 3d, when the position of the limit plate 3b needs to be adjusted, it is only necessary to rotate the adjustment rod 3f. Rotating the adjustment rod 3f will cause it to move up and down in the adjustment hole 3a1, thereby pushing or pulling the adjustment plate 3d to adjust the compression degree of the elastic member 3c. This adjustment method is intuitive and easy to operate, and even non-professionals can easily get started. In addition, by rotating the adjusting rod 3f for fine adjustment, the position of the limit plate 3b can be precisely controlled. Whether it is necessary to slightly increase the clamping force or reduce the clamping force, it can be achieved by fine-tuning the adjusting rod 3f. This accuracy ensures the stability of the NdFeB magnetic steel workpiece 4 on the placement bracket 2 and avoids production problems caused by displacement. In addition, it also makes the entire bracket more adaptable.
[0032] Further, refer to Figure 4 and Figure 5 As shown, the limit compensation mechanism 3 also includes a limit rod 3g, a limit hole 3a2 is provided on the fixed seat 3a, the limit rod 3g is movably arranged in the limit hole 3a2, and one end of the limit rod 3g passes through the limit hole 3a2 and is fixedly connected to the limit plate 3b. Specifically, through the cooperation of the limit rod 3g and the limit hole 3a2, the moving direction of the limit rod 3g in the limit hole 3a2 is limited, so that the limit rod 3g can stably slide in the limit hole 3a2 when subjected to external force, without shaking or deflection. At the same time, because one end of the limit rod 3g passes through the limit hole 3a2 and is fixedly connected to the limit plate 3b. This connection method enables the limit plate 3b to transmit the force to the fixed seat 3a through the limit rod 3g when subjected to external force, thereby realizing the restriction of the moving direction of the limit plate 3b. Through this structure, the movement of the limit plate 3b on the placement bracket 2 is strictly controlled within a predetermined direction, avoiding the displacement of the NdFeB magnetic steel workpiece 4 in an uncontrolled direction. In addition, the cooperation between the limit rod 3g and the limit hole 3a2 also enhances the stability and durability of the entire limit compensation mechanism 3. Since the movement of the limit rod 3g in the limit hole 3a2 is limited, the limit plate 3b will not easily fall off or be damaged even under the action of external force. Thereby improving the safety and reliability of the bracket, providing a strong guarantee for the stacking of NdFeB magnetic steel.
[0033] Further, refer to Figure 5 As shown, the limit compensation mechanism 3 also includes a limit stopper 3h, which is arranged at one end of the limit rod 3g away from the limit plate 3b. Specifically, the main function of the limit stopper 3h is to limit the movement range of the limit rod 3g to prevent it from excessively sliding out of the limit hole 3a2. When the limit rod 3g moves in the limit hole 3a2, the limit stopper 3h will contact the fixed seat 3a, thereby playing a blocking role. This ensures that the limit rod 3g will not accidentally fall out of the limit hole 3a2 when subjected to external force, thereby ensuring the stability and reliability of the entire limit compensation mechanism 3.
[0034] Further, refer to Figure 3 and Figure 5 As shown, the elastic member 3c is a spring, which is wound on the outside of the limit rod 3g. As a common elastic element, the spring has excellent elasticity and recovery performance. In the limit compensation mechanism 3, the spring is wound on the outside of the limit rod 3g. When the NdFeB magnetic steel workpiece 4 changes in size or is subjected to external force on the placement bracket 2, the spring can be telescopically deformed according to the actual situation, thereby realizing the precise adjustment of the limit plate 3b. This design enables the limit plate 3b to always maintain close contact with the NdFeB magnetic steel workpiece 4, effectively preventing the displacement of the magnetic steel. At the same time, the way the spring is wound on the outside of the limit rod 3g also simplifies the structure of the mechanism, making the entire limit compensation mechanism 3 more compact and stable. This design not only improves the space utilization of the bracket, but also reduces the manufacturing cost and maintenance difficulty. In addition, the material and performance of the spring can also be selected and optimized according to specific needs. For example, a spring material with a higher elastic modulus and better fatigue resistance can be selected to ensure that the spring can maintain stable performance during long-term use.
