Description

Technical Field

[0001] This utility model relates to the field of long stator core manufacturing, specifically to an electromagnetic induction curing device for long stator cores. Background Technology

[0002] In maglev trains, the long stator linear motor is a core component. The long stator core is the heart of the long stator linear motor, providing the most robust guarantee for the maglev train's levitation, traction, and braking functions. However, due to its considerable length, the long stator core is prone to problems during the heating and curing process. If the heating time is too short, the core may not adhere properly, or the heating may be uneven, causing it to detach in the middle. This necessitates a long heating time for the long stator core, especially when mass production is required, as the significant time needed for curing the core results in low overall manufacturing efficiency. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background technology and provide an electromagnetic induction curing device for long stator cores.

[0004] The technical solution adopted by this utility model is as follows: a long stator core electromagnetic induction curing device, including a body, an induction heating mechanism, a pushing mechanism and a core tooling connected to the body, wherein the induction heating mechanism is fixedly connected to the pushing mechanism, and the pushing mechanism controls the induction heating mechanism to move closer to or away from the core tooling.

[0005] Furthermore, it also includes a moving mechanism, which is fixed to the machine body, and the core tooling is slidably mounted on the moving mechanism.

[0006] Furthermore, the induction heating mechanism includes an induction coil, which is fixedly connected to the pushing mechanism via a connecting block.

[0007] Furthermore, the propulsion mechanism includes a power assembly and a landing gear. The power assembly is fixed to the fuselage via a mounting bracket. The landing gear is vertically and vertically connected to the mounting bracket via stepped screws under the action of the power assembly. The landing gear is fixedly connected to the induction coil.

[0008] Furthermore, the power assembly includes a hydraulic shaft and a spindle connected together, the hydraulic shaft being fixedly connected to the fixed frame, and the induction coil being uniformly wound around the outer circumference of the spindle.

[0009] Furthermore, the fixing frame is composed of multiple fixing columns, which are fixed together by a first fastening screw.

[0010] Furthermore, the moving mechanism includes a guide rail fixed to the machine body, and the core tooling is slidably mounted on the guide rail.

[0011] Furthermore, the induction coil is fixed to the connecting block by a second fastening screw.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: the induction heating mechanism is brought close to the iron core fixture by the pushing mechanism to perform electromagnetic induction heating, thereby achieving rapid heating and temperature rise, which greatly shortens the curing time of the long stator iron core and improves production efficiency. At the same time, the iron core fixture can be quickly moved into the heating zone of the equipment by the moving mechanism, and can be quickly removed from the heating zone after heating and curing.

[0015] To further understand this utility model, the embodiments and comparative examples will be described in more detail below, but the implementation of this utility model is not limited thereto.

[0016] To make the objectives and technical solutions of this utility model clearer, the following detailed description, in conjunction with examples, further illustrates this utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. The application process of this utility model is described in detail below.

[0017] Please refer to Figure 1 As shown, an electromagnetic induction curing device for a long stator core includes a body 1, an induction heating mechanism 22, a pushing mechanism 33 connected to the body 1, and a core fixture 11. The induction heating mechanism 22 is fixedly connected to the pushing mechanism 33, and the pushing mechanism 33 controls the induction heating mechanism 22 to move closer to or away from the core fixture 11.

[0018] By using the pushing mechanism 33 to bring the induction heating mechanism 22 close to the iron core fixture 11, electromagnetic induction heating is performed, achieving rapid heating and temperature rise, which greatly shortens the curing time of the long stator iron core and increases production efficiency. Using the induction heating mechanism 22 for electromagnetic induction heating reduces the curing time from 2-3 hours compared to conventional oven heating to only about 30 minutes, greatly shortening the curing time and improving production efficiency.

[0019] In a specific embodiment, a moving mechanism 44 is also included. The moving mechanism 44 is fixed on the machine body 1, and the iron core fixture 11 is slidably disposed on the moving mechanism 44.

[0020] The core fixture 11 can be quickly moved into the heating zone of the equipment using the moving mechanism 44, and can be quickly removed from the heating zone after heating and curing, thereby improving the overall working efficiency of the long stator core.

[0021] In a specific embodiment, the induction heating mechanism 22 includes an induction coil 4, which is fixedly connected to the pushing mechanism 33 via a connecting block 9.

[0022] In a specific embodiment, the propulsion mechanism 33 includes a power component and a landing gear 5. The power component 331 is fixed to the body 1 by a fixing frame 55. Under the action of the power component 331, the landing gear 5 is vertically connected to the fixing frame 55 by a step screw 6. The landing gear 5 is fixedly connected to the induction coil 4.

[0023] The stepped screw 6 has a stepped structure. After being inserted into the material being connected, it can provide additional connecting material, which can ensure the smoothness of the landing gear 5 during the lifting process, ensure the positional stability of the induction coil 4 during descent, and improve heating stability.

[0024] In a specific embodiment, the power assembly 331 includes a hydraulic shaft 7 and a spindle 3 connected together. The hydraulic shaft 7 is fixedly connected to the fixed frame 55, and an induction coil 4 is uniformly wound around the outer circumference of the spindle 3.

[0025] In a specific embodiment, the fixing frame 55 is composed of multiple fixing columns 8, which are fixed together by a first fastening screw 12.

[0026] In a specific embodiment, the moving mechanism 44 includes a guide rail 2 fixed to the machine body 1, and the core fixture 11 is slidably mounted on the guide rail 2. The core fixture 11 is fed into or removed from the heating zone via the guide rail 2.

[0027] In a specific embodiment, the induction coil 4 is fixed to the connecting block 9 by the second fastening screw 10.

[0028] The working principle of this utility model is as follows: Multiple fixing columns 8 are installed on the machine body 1 to form a fixing frame 55. The fixing columns 8 are fixed and locked together by the first fastening screw 12. Then, the landing gear 5 is connected and fixed by the step screw 6. The induction coil 4 is fixed to the landing gear 5 by the connecting block 9 and the second fastening screw 10. When the long stator core needs to be heated and cured, the stator laminations are fixed and stacked by the core fixture 11. Then, the core fixture 11 is placed on the machine body 1 and moved into the heating zone of the equipment by the guide rail 2. When the power is on, the landing gear 5 is lowered by the hydraulic shaft 7. Guided by the mandrel 3, the induction coil 4 is lowered above the core fixture 11. As the induction coil 4 heats up, the temperature rises rapidly, completing the heating of the long stator core. After the heating is completed and the core is completely cooled and cured, the core fixture 11 is moved out of the heating zone of the machine body 1 by the guide rail 2. Finally, the core fixture 11 is removed to obtain the long stator core. By using electromagnetic induction heating, the time required for curing in a conventional oven, which used to take 2 to 3 hours, is reduced to only about 30 minutes, greatly shortening the curing time and improving production efficiency.
