Abstract
The invention discloses a split joint method of amorphous C type magnetic cores, which comprises the process steps of coiling, forming annealing, and lacquer dipping and curing forming. The invention is characterized in that the split joint method concretely comprises the following steps: (1) coiling narrow-band magnetic cores: selecting two or more than two amorphous C type magnetic cores with the width sum equal to the required width according to the amorphous C type magnetic cores with the required width; (2) carrying out forming annealing, wherein each magnetic core carries out annealing singly; (3) carrying out lacquer dipping and curing forming on two or more than two narrow-band magnetic cores; (4) gluing and overlapping two or more than two narrow-band magnetic cores, wherein the two or more than two narrow-band magnetic cores are mutually aligned during the gluing; (5) carrying out integral cutting; and (6) carrying out baking tidying, finished product detection and package. The technical method of the invention has the advantages of simplicity and convenient operation., effectively solves the problem of difficult split joint of the super-wide amorphous C type magnetic cores, and has better magnetic core performance, in addition, the narrow-band magnetic cores can be easily dipped during lacquer dipping, the lacquer dipping is more sufficient, and the noise is lower.
Description
Technical field
The present invention relates to the magnetic core manufacture craft of amorphous material, specifically relate to the joining method of the amorphous ribbon C type magnetic core of the above width of 60mm.
Background technology
The splicing of the amorphous C type magnetic core of prior art generally is directly to batch with the broadband shear because the amorphous ribbon of the above width of 60mm is difficult, and consistent evenly difficult control of the form forming magnetic core after annealing temperature of broader bandwidth, demoulding difficulty, dipping lacquer also difficulty soak into.Cause the core loss height, the high harm of noise.As Chinese patent application number be 89106983, the applying date is that September 3, denomination of invention in 1989 are making method of cutting amorphous inductive magnetic core, Granted publication day to be the application for a patent for invention on March 31st, 1993; the magnetic core method for making of this amorphous soft magnetic material; be to use the mother metal of vacuum metling; make the amorphous band of Rack with single-roller method; coiled annular or rectangle magnetic core; under the protection of nitrogen or argon gas, carry out annealing in process then; adopt epoxy resin envelope magnetic core afterwards; through the cured moulding, carry out the air gap cutting at last.Said method is directly to batch with the broadband equally, equally also has the situation of difficult shearing for the amorphous ribbon as the above width of 60mm of broad.
Summary of the invention
Purpose of the present invention is exactly in order to solve the deficiency of prior art, and a kind of method of can be effectively splicing at the amorphous ribbon C type magnetic core of super width more than the 60mm that provides, the magnetic core performance that this method is spliced is more excellent.
The present invention adopts following technical solution to realize above-mentioned purpose: this joining method comprises the steps:
(1), rolls narrow-band magnetic cores:, choose the amorphous C type magnetic core that two or more width additions equal required width according to the amorphous C type magnetic core of required width;
(2) adopt prior art to carry out moulding annealing, and the single annealing of each magnetic core;
(3) with two or more narrow-band magnetic cores dipping lacquer solidifying and setting;
(4) two or more narrow-band magnetic cores bondings are superimposed, and two or more magnetic cores align when bonding;
(5) integral cutting;
(6) dry finishing, finished product detection, packing.
The beneficial effect that the invention process such scheme can reach is:
1. the broadband is divided into the independent coiling in the approaching arrowband of two or more width in the time of will reeling, and it is more convenient to reel; And single annealing, paint-dipping drying.Because single magnetic core is gently little, annealing temperature is easier to be reached evenly, and the magnetic core performance is more excellent, and the easier infiltration dipping lacquer of narrow bandwidth dipping lacquer is more abundant, and noise is lower.
2. the two or more magnetic cores that dipping lacquer is baked align, and strong with bonding force between two or more core layer, the epoxy adhesive that stress is low is bonded into integral body.
3. the magnetic core one piece that bonding folded assembly is formed cuts into the U type.
Splicing process method of the present invention is simple, easy to operate, has solved the problem that super wide amorphous ribbon C type magnetic core is difficult to splice effectively.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Embodiment
As shown in Figure 1, as the amorphous ribbon C type magnetic core of need splicing 65mm width, the broadband is divided into two independent coilings in arrowband that width is approaching in the time of at first will reeling, as: 65mm=35mm+30mm, roll up respectively 35mm high with the C type magnetic core that 30mm is high, and and single annealing, paint-dipping drying.Because single magnetic core is gently little, annealing temperature is easier to be reached evenly, and the magnetic core performance is more excellent, and the easier infiltration dipping lacquer of narrow bandwidth dipping lacquer is more abundant, and noise is lower.
Then, two magnetic cores that dipping lacquer is baked align, and strong with bonding force between two core layer, the epoxy adhesive that stress is low is bonded into integral body.
At last, the magnetic core one piece that bonding folded assembly is formed cuts into the U type, and carries out dry finishing, finished product detection, packing and get final product.
Such scheme only is preferred embodiment, and the technology of the present invention is not limited to the foregoing description, and any those skilled in the art all can do numerous modifications and variations, is not breaking away under the spirit of the present invention, all in the claimed scope of the present invention.
