Description
Technical field
The present invention relates to magnetic core technical field of manufacturing process, and in particular to a kind of manufacture craft of laminated magnetic core.
Background technique
Magnetic core: magnetic core refers to a kind of sintering magnetic metal oxide being made of various iron oxide mixtures.For example, manganese-
Zn ferrite and nickel-zinc ferrite are typical magnetic core array materials.Manganese-zinc ferrite has high magnetic permeability and high magnetic flux density
Feature, and there is more low-loss characteristic.Nickel-zinc ferrite has high unit area impedance, less than spies such as several hundred low magnetic permeabilities
Property.FERRITE CORE is in the coil and transformer of various electronic equipments.
American physicist Wang An nineteen fifty proposes the thought using magnetic material manufacture memory.Bill Forrester then will
This thought becomes reality.In order to realize that magnetic core stores, Bill Forrester needs a kind of substance, and this substance should have one
Explicitly magnetize very much threshold value.He finds the German Lao Tao in a company of New Jersey's production television set ferrite converter
Porcelain expert obtains specific magnetic property using fusing iron ore and oxide.
It is the key that design to clear threshold value is magnetized with.The grid and fuse of this electric wire are woven in wire mesh, by person
It is stored for fuse, its related patent is very crucial to computer is developed.This scheme is reliable and stablizes.Magnetization is comparatively
It is permanent, so the data of storage still maintain after the power supply of system is closed.Since magnetic field energy is come with the speed of electronics
It reads, this has interactive calculating may.Further, because being electric wire grid, any part of storage array can be visited
It asks, that is to say, that different data can store the different location in wire mesh, and read a branch of bit of position just
It can immediate access.This is known as random-access memory (ram), it is the interactive innovation concept calculated.Bill Forrester is these
Patent transfers the Massachusetts Institute of Technology, and institute leans on these patents to receive 15,000,000~20,000,000 dollars every year.
That obtain these patent licenses at first is IBM, and IBM is finally obtained in the installation " rotation of North America defence military base
The commercial contract of wind ".Importantly, all large-scale and medium-size computers also use this since the 1950s
System.Magnetic core storage is from the 1950s, the sixties, until at the beginning of the seventies, be always the standard mode of computer hosting.
Previous similar products technique is coiling, the iron core completed with wrapping machine according to circle number setting, the disadvantage is that magnetic conduction
Rate is not linear, height loss, without good frequency characteristic and temperature stability.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of manufacture craft of laminated magnetic core,
It solves magnetic core magnetic permeability linear problem, has the problem of good frequency characteristic and low-loss and temperature stability, change
The molding mode of material changes into lamination process from the initial winding method of production, changes the various property of product significantly
Energy index, changes manufacture craft, expands the application field of material.
To achieve the above object, the present invention is using following technical scheme: a kind of manufacture craft of laminated magnetic core, feature
It is, it is comprised the steps of:
Step 1: selection；Select amorphous 1k101 material, alloy material of the thickness in 15um to 30um；

After take out punching fast cooling to room temperature；
Step 6: secondary crystallization；It drops to after room temperature and puts into the amorphous annealing furnace punching is secondary, 450 DEG C keep the temperature 120 points
Clock makes punching complete crystallization, closes amorphous annealing furnace, takes out punching；
Step 7: setting temperature；Oven is opened, 180 DEG C of preset temperature；
Step 8: baking-curing；The good punching of crystallization is adjusted elasticity and height on special core model, tightens screw,
The punching put on is put into impregnate in curing agent and takes out and dries after twenty minutes, the punching after the solidification is put into oven
Carry out 180 DEG C of heat preservations, 200 minutes baking-curings；
Step 9: quality inspection finished product；After magnetic core is removed from core model, measure the magnetic permeability linearity of magnetic core, loss, frequency characteristic and
Temperature stability is to get a kind of laminated magnetic core.
Curing agent in the step 8 includes epoxy resin A glue 100-105g, epoxy resin B glue 130-135g, dilution
Agent 1kg.
Fast cooling in the step 5 uses fan or air-cooler fast cooling.
Special core model is stainless steel core die in the step 4.
Special core model includes pedestal, screw hole, screw rod in the step 4, has been provided with screw among the pedestal
Hole, the both ends of the core model have screw rod, and on pedestal, the other end is screwed down across cover board and put described core model one end lemon
Into in amorphous furnace.
The screw hole is the screw hole of M8.
After adopting the above technical scheme, having very well the invention has the following beneficial effects: solving magnetic core magnetic permeability linear problem
Frequency characteristic and low-loss and the problem of temperature stability, change the molding mode of material, from production it is initial around
Mode processed changes into lamination process, changes the various performance indicators of product significantly, changes manufacture craft, expand material
Application field.
