Embodiment Construction
[0021] The winding body in the present invention is embedded in magnetic powder and pressed, and the magnetic powder is loaded into the powder molding machine twice, that is, the magnetic powder is first added into the mold cavity of the powder molding machine, then the winding body is put into the winding body, and then the magnetic powder is added again. Powder, the amount of powder added twice is suitable for laying the winding body in the middle of the integrated inductor.
[0022] The present invention will be further described below in conjunction with accompanying drawing
[0023] Concrete manufacture method of the present invention is as follows:
[0024] (1) First lift the die plate 9, and drive the die 8 to rise to a certain height, so that a mold cavity is formed between the die 8 and the lower die punch 12, the core rod 10, the core rod backing plate 11, the rod 14, and the core rod plate 15 and the core rod connecting rod 17 are driven upward by the core rod cyli...

The invention discloses a method for manufacturing an integrated inductor, and relates to a method for manufacturing an electrical element. The integrated inductor is formed by embedding and pressing a winding body into magnetic powder; and the magnetic powder is filled into a powder forming machine twice, namely the magnetic powder is added into a die cavity of the powder forming machine first, then the winding body is put into the powder forming machine, and the magnetic powder is added into the powder forming machine again; and the twice added powder ensures that the winding body is arranged in the middle part of a seat body of the integrated inductor. The integrated inductor adopts twice powder adding technology, ensures that a winding in the middle of the magnetic powder is stressed evenly and vertically and the stresses of stubs of the winding are mutually counteracted to ensure the integrity of the stubs of the winding; and the demoulding adopts a bidirectional demoulding mode to ensure that the lateral surface of a blank does not produce cracks.
Description
technical field [0001] The invention relates to a manufacturing method of an electrical component, in particular to a manufacturing method of an integrated inductor. Background technique [0002] The integrated inductor has higher inductance and smaller leakage inductance, so it has become the main manufacturing method for manufacturing inductors. The traditional domestic method of manufacturing integrated inductors uses one-time powder addition, which is often due to uneven distribution of magnetic powder on the upper and lower windings. , causing the solder joints of the winding pins to break easily, and the products that are released from the mold are easy to crack and the molding rate is low. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing an integrated inductor with simple operation and high molding rate in view of the above defects. [0004] The technical solution of the present invention is: the windi...
