Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for iron teeth and iron cores, specifically to a heat treatment device for iron teeth and iron cores. Background Technology

[0002] Iron cores are widely used in the main magnetic circuit of transformers. They are produced by rolling thin plates and then winding them. As the main magnetic circuit in a transformer, the iron core has high requirements for its magnetic properties. In order to eliminate stress and recrystallize to obtain better magnetic properties, heat treatment is required after production.

[0003] In existing technologies, during actual use, because the inner wall of the workpiece is farther from the heat source than the outer wall, the temperature of the inner wall is lower than that of the outer wall during heating. As the hot gas moves from the uppermost inner wall to the lowermost inner wall driven by the circulating fan, the heat of the hot gas is continuously absorbed, resulting in uneven axial heating of the inner walls of workpieces at different heights. This leads to incomplete processing of some workpieces. For iron cores, incomplete processing will prevent them from achieving the specified magnetic induction value, thereby reducing the pass rate and significantly affecting the production efficiency of iron cores. Therefore, it is necessary to improve the iron tooth and iron core heat treatment device to solve the above problems. Utility Model Content

[0027] Example 1:

[0028] Please see Figure 1-5 This utility model provides a technical solution: a heat treatment device for iron teeth and iron cores, including a medium frequency heating box 1, a controller 2 fixedly connected to the right side of the medium frequency heating box 1, a protective door 3 provided on the front of the medium frequency heating box 1, a support leg 4 fixedly connected to the bottom of the medium frequency heating box 1, a movable installation mechanism 5 provided inside the medium frequency heating box 1, and an auxiliary heat treatment mechanism 6 provided inside the medium frequency heating box 1.

[0030] Furthermore, the active component 51 includes a motor 511, which is fixedly connected to the left side of the intermediate frequency heating box 1. The output end of the motor 511 extends through the intermediate frequency heating box 1 and is fixedly connected to a connecting shaft 512. A connecting plate 513 is fixedly connected to the outside of the connecting shaft 512. A support frame 514 is fixedly connected to the outside of the connecting shaft 512. A connecting rod 515 is rotatably connected inside the support frame 514. A gear column 516 is fixedly connected to the outside of the connecting rod 515. A first bevel gear 517 is fixedly connected to the outside of the connecting rod 515. A mounting platform 518 is rotatably connected inside the support frame 514. A second bevel gear 519 is fixedly connected to the end of the mounting platform 518 near the first bevel gear 517. A gear ring frame 5110 is fixedly connected inside the intermediate frequency heating box 1. This facilitates the iron tooth core to rotate on its own axis while following the revolution of the connecting shaft 512, thereby satisfying the requirement of uniform heat treatment of the iron tooth core and increasing the treatment effect.

[0031] Furthermore, the first bevel gear 517 meshes with the second bevel gear 519, and the gear post 516 meshes with the gear ring holder 5110, which facilitates a more stable operation.

[0032] Furthermore, the mounting assembly 52 includes a connecting platform 521, which is fixedly connected inside the mounting platform 518. A threaded rod 522 is rotatably connected inside the connecting platform 521, and a limit rod 525 is fixedly connected inside the connecting platform 521. A movable plate 523 is slidably connected to the outside of the limit rod 525. A core mounting bracket 524 is provided on the inner side of the movable plate 523. A locking block 526 is fixedly connected to one end of the movable plate 523 near the core mounting bracket 524, which facilitates the adjustment of the position of the locking block 526, thereby meeting the limit installation requirements for different models of core mounting brackets 524.

[0033] Furthermore, the iron core mounting bracket 524 has a slot at the corresponding position of the locking block 526, and the locking block 526 is inserted into the slot. The movable plate 523 is threadedly connected to the threaded rod 522, and the movable plate 523 is slidably connected to the connecting table 521, which facilitates a more stable installation process.

[0034] Example 2:

[0035] Based on Example 1, please refer to Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary heat treatment mechanism 6 includes a circulating fan 61, which is fixedly connected to the back of the intermediate frequency heating box 1. A support plate 62 is fixedly connected to the inner side of the bottom of the intermediate frequency heating box 1. An air outlet plate 63 is rotatably connected inside the support plate 62. A limit plate 64 is fixedly connected to the outside of the air outlet plate 63. An electric telescopic rod 65 is fixedly connected to the bottom of the intermediate frequency heating box 1. A limit block 66 is fixedly connected to the top of the electric telescopic rod 65, which facilitates the adjustment of the angle of the air outlet plate 63, thereby increasing the uniformity of heating of the iron teeth and iron core.

[0036] Furthermore, the limiting plate 64 and the limiting block 66 are provided with grooves at corresponding positions, and the limiting block 66 is movably connected inside the groove, which makes the adjustment process more stable.

[0037] In actual operation, when this device is used, the threaded rod is first used as a T-type threaded rod to give it self-locking properties. After the operator places the iron core mounting bracket 524 inside the movable plate 523, they use tools such as a hex wrench to rotate the threaded rod 522. The rotation of the threaded rod 522, in conjunction with the limit rod 525, causes the movable plate 523 to move, thereby moving the locking block 526 until it is inserted and limited with the iron core mounting bracket 524. After installation, the iron tooth core that needs to be heat-treated is placed outside the iron core mounting bracket 524 and installed. After closing the protective door 3, the controller 2 is activated, and the medium frequency heating box 1 begins the heat treatment operation on the iron tooth core. The motor 511 operates, causing the connecting shaft 512 to rotate. This, in conjunction with the connecting plate 513 and the first bevel gear 517, causes the gear column 516 to move. This, in conjunction with the gear ring frame 5110, causes the connecting rod 515 to rotate inside the support frame 514, thereby causing the first bevel gear 517 to rotate. This, in conjunction with the second bevel gear 519, causes the mounting platform 518 to rotate inside the support frame 514. This causes the iron tooth core to rotate on its own axis while following the revolution of the connecting shaft 512. The circulating fan 61 operates, in conjunction with the air outlet plate 63, to circulate the hot air inside the medium frequency heating box 1. The electric telescopic rod 65 operates, causing the limit block 66 to move. This, in conjunction with the limit plate 64, causes the air outlet plate 63 to rotate inside the support plate 62.
