Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a high-strength pressing device for the production of iron-silicon-aluminum soft magnets, including a base 1, a rotating table 2, a pressing mold 3, a hydraulic cylinder 4, and a pressing column 5. The rotating table 2 is rotatably connected to the surface of the base 1, and the pressing mold 3 is fixedly connected to the surface of the rotating table 2. A rotating disk 6 is provided at the connection between the rotating table 2 and the base 1. A gear ring 7 is fixedly connected to the side wall of the rotating disk 6. A stepper motor 8 is fixedly connected to the side wall of the base 1. A drive gear 9 is fixedly connected to the output end of the stepper motor 8. The drive gear 9 meshes with the gear ring 7. The pressing column 5 is provided on the side wall of the base 1. A support seat 10 and a mounting seat 11 are fixedly connected to the side wall of the pressing column 5. The hydraulic cylinder 4 is fixedly connected to the lower surface of the mounting seat 11.

[0021] In a further improvement, the pressing mold 3 includes a lower mold 12 and an upper mold 13. The lower mold 12 is fixedly connected to the surface of the rotating table 2, and the upper mold 13 is fixedly connected to the output end of the hydraulic cylinder 4. By installing the upper mold 13 at the output end of the hydraulic cylinder 4 and connecting it with the lower mold 12 on the surface of the rotating table 2, it is convenient to quickly compact the alloy powder.

[0022] In a further improvement, a pad 14 is fixedly connected to the surface of the support base 10, and an electromagnet 15 is fixedly connected to the lower surface of the pad 14. By fixing the pad 14 with the electromagnet 15 to the surface of the support base 10, it is convenient to adsorb and fix the rotating table 2, thereby improving the stability of the rotating table 2 during the pressing process.

[0023] Further improvements include a fastening bolt 16 at the connection between the mounting base 11 and the pressing column 5, and a plurality of evenly distributed fixing holes 17 on the surface of the mounting base 11. By providing evenly distributed fixing holes 17 on the surface of the mounting base 11, the installation height of the mounting base 11 can be easily adjusted according to production needs, making it easy to adapt to pressing molds 3 of different heights.

[0024] In a further improvement, a positioning groove 18 is provided at the connection between the rotating platform 2 and the lower mold 12, and a pressure plate 19 is provided at the edge of the positioning groove 18. The surface of the pressure plate 19 is provided with fixing bolts 20. By providing a positioning groove 18 on the surface of the rotating platform 2, the installation accuracy between the lower mold 12 and the rotating platform 2 is improved. In conjunction with the pressure plate 19 with fixing bolts 20, the stability of the connection between the lower mold 12 and the rotating platform 2 is improved.

[0025] In use, alloy powder is poured into the lower mold 12. The controller controls the stepper motor 8, which is connected to the gear ring 7, to drive the rotating disk 6 to rotate, so that the lower mold 12 on the surface of the rotating disk 6 can be sent to the lower part of the upper mold 13. The controller controls the electromagnet 15 to be energized to attract and fix the rotating table 2, so as to prevent the rotating table 2 from moving. The controller drives the hydraulic cylinder 4 to extend through the control valve, pressing the upper mold 13 into the lower mold 12, thereby pressing and shaping the alloy powder. At the same time, the support seat 10 bears the pressure of the hydraulic cylinder 4, which increases the compaction density of the alloy powder, thereby enhancing the strength of the iron-silicon-aluminum soft magnet. After pressing, the rotating table 2 drives the lower mold 12 to rotate cyclically, which improves the working efficiency of iron-silicon-aluminum soft magnet production.

[0026] The problem solved by this invention is that the production of iron-silicon-aluminum soft magnetic cores is usually carried out using powder metallurgy. During the pressing process, hydraulic cylinders are required in conjunction with the base to apply pressure, which often places high demands on the structural strength of the overall pressing equipment. Some frame-type pressing equipment does not provide sufficient pressing force for the powder, affecting the structural strength of the iron-silicon-aluminum soft magnetic cores. This invention utilizes a pressing device composed of a base 1, a rotating table 2, a pressing mold 3, a hydraulic cylinder 4, and a pressing column 5. On the one hand, the rotating table 2 drives the pressing mold 3 to rotate, improving the efficiency of iron-silicon-aluminum soft magnetic product production. On the other hand, the pressing column 5 bears the extrusion force of the hydraulic cylinder 4, increasing the pressing density of the iron-silicon-aluminum soft magnetic cores and effectively enhancing their structural strength.
