Abstract

The invention discloses a manufacturing method of an electromagnet. The manufacturing method comprises the following steps of: (1) preparing 6-10 E-shaped electrical pure iron sheets, wherein DT4E is adopted for the E-shaped electrical pure iron sheets; (2) stamping a lug boss and a groove at the same position of the middle sheet column of each E-shaped electrical pure iron sheet; (3) performing heat treatment on each E-shaped electrical pure sheet; (4) stacking the E-shaped electrical pure iron sheets and putting the stacked E-shaped electrical pure iron sheets into a framework to obtain an electromagnet self-finished product; (5) performing a blackening treatment; and (6) rinsing the electromagnet self-finished product with hot soap water after the blackening treatment, then fully stirring and flushing with cold water and drying to obtain the electromagnet finished product. The manufacturing method of the electromagnet has the beneficial effects that: as the 6-10 DT4E electrical pure iron sheets are stacked together, deviation generated in the stamping process is reduced, deviation generated in an assembling process is removed, a suction force of the electromagnet is increased, a residual magnetic force is reduced, and the requirement that the suction force of not less than 30 N and the residual magnetic force of not greater than 0.6 is realized.

Description

technical field [0001] The invention relates to a manufacturing method of an electromagnet, which belongs to the technical field of electronic magnetic components. Background technique [0002] The electromagnet is wound on the skeleton according to the technical requirements and then loaded into the iron core. After the DC voltage is applied, the electromagnet will have a suction force according to the law of electromagnetic induction. Finally, the circuit is disconnected, the suction force of the electromagnet disappears, and the armature returns to its original position. [0003] At present, after the wire is wound on the skeleton, multiple pieces of silicon steel sheet iron core with a thickness of 0.5 or 0.35mm are loaded in the industry. The silicon steel sheet should be inserted tightly and the suction surface should be flat. The unevenness of the suction surface is caused by the deviation of the silicon steel sheet during the punching process and the deviation durin...
