[0017] The following further elaborates on the present utility model in detail with reference to the drawings and specific embodiments.
[0018] As Figures 1-3 shown, a shaping jig for a rectangular magnetic core based on nanocrystalline material of the present utility model includes a limiting frame 1. A fixing frame 2 is connected to the middle of the limiting frame 1. The fixing frame 2 divides the limiting frame 1 into several shaping grooves. A shaping plate 3 is arranged in the shaping grooves, and a shaping block 4 is arranged in the middle of the shaping grooves. The circular magnetic core is placed in the shaping groove formed by the fixing frame 2 and the shaping plate 3, and then the middle of the magnetic core is shaped by the shaping block 4 to obtain a rectangular magnetic core. By increasing the number and size of the shaping grooves, the problems of producing a small number and small-sized magnetic cores by the traditional shaping jig are solved, thereby improving the production efficiency, reducing the labor cost, being convenient, efficient and practical.
[0019] Further, the shape of the fixing frame 2 is "丰" (Chinese character for abundance). The fixing frame 2 in the shape of "丰" can reduce the grooving process and has good practicability.
[0020] Further, the shaping grooves are evenly distributed. The evenly distributed shaping grooves have good stability and can be shaped in batches.
[0021] [[ID=id=38]]Further, the shaping grooves are of a hollow structure. The hollow-structured shaping grooves are convenient for taking and placing.
[0022] Furthermore, in this invention, the shaping block 4 includes two sub-shaping blocks 8, the longitudinal cross-section of which is trapezoidal and centrally symmetrical. The two centrally symmetrical sub-shaping blocks 8 with trapezoidal longitudinal cross-sections can be combined to form a rectangular column. During shaping, the sub-shaping blocks 8 can be placed sequentially in the center of the magnetic core for shaping the center of the magnetic core. Moreover, the rounded edges ensure uniform core stress when the circular magnetic core is made into a rectangular magnetic core, preventing uneven core stress during heat treatment.
[0023] Furthermore, in this invention, both ends of the limiting frame 1 are connected to the handle 5 via second screws 7, and the middle of each handle 5 is connected to the limiting frame 1 via a first screw 6. The limiting frame 1 is connected to the fixing frame 2 via the first screw 6. The limiting frame, fixing frame 2, and handle 5 are connected and fixed using the first screw 6, and the second screws 7 on both ends of the handle 5 are tightened to facilitate the handling of the fixture.
[0024] The working principle of this utility model is as follows:
[0025] Before production, the circular magnetic core is placed into each shaping slot in sequence. Then, two sub-shaping blocks 8 (i.e., shaping blocks that form a rectangular block) are placed in the middle of the circular magnetic core. The fixing bracket 2 is then placed into the corresponding slot and pushed into the magnetic core. It is then fixed by the first screw 6 and the second screw 7. After that, the entire fixture is placed in an oven for high-temperature baking and shaping. After shaping, the two sub-shaping blocks 8 are removed from the middle of the magnetic core in sequence, and then the rectangular magnetic core is removed to complete the process. It is convenient, efficient and practical.
