Preparation method of inductor

The invention relates to the technical field of inductors, in particular to a preparation method of an inductor, I-Core and O-Core are respectively prepared from a composite material, in the preparation process, a cold press is adopted for cold press molding, and the pressure during cold press is 1.5-2 Ton; a copper wire is wound into a coil through a winding machine, then the two ends of the coil are bent into pins, U-Core is prepared from a composite material, a cold press is adopted for cold press forming in the preparation process, the pressure during cold press is 5.5-6 Ton, the coil, I-Core and O-Core are sequentially put into the U-Core to form a blank, and finally the blank is conveyed to a hot press for hot press forming. 本发明涉及电感器的技术领域，它涉及一种电感器的制备方法，通过复合材料分别制备I-Core和O-Core，该制备过程中采用冷压机冷压成型，冷压时的压力为1.5-2Ton；通过绕线机将铜线绕至成线圈后对线圈的两端弯折成引脚，通过复合材料制备U-Core，该制备过程中采用冷压机冷压成型，冷压时的压力为5.5-6Ton，将线圈、I-Core和O-Core依次放入U-Core内，形成胚料，最后将胚料送至热压机进行热压成型。
