Abstract

The invention discloses the manufacture method of a kind of EP type magnetic ferrite magnetic core, the process that grinds of EP type magnetic ferrite magnetic core uses belt through-type grinding machine equipment, the limit foot opening direction of EP type magnetic ferrite magnetic core is consistent with passing through type grinder equipment upper conveyor belt direction of advance and utilizes the air gap emery wheel being arranged on passing through type grinder that the center pillar of EP type magnetic ferrite magnetic core is carried out grinding, and the polishing width of the air gap emery wheel being arranged on passing through type grinder is slightly larger than the diameter of the center pillar of EP type magnetic ferrite magnetic core.Use the center pillar of this method grinding EP type magnetic ferrite magnetic core, the center pillar end face of EP type magnetic ferrite magnetic core can be made all to be ground to man-hour adding, grinding process can be identical with processing common magnetic core (EE, EC, EFD, RM), without other techniques of otherwise designed, this method is greatly improved process velocity, without manual operation, do not interfere with other performances of EP magnetic core simultaneously.

Description

A kind of manufacture method of EP type magnetic ferrite magnetic core
Technical field
The present invention relates to a kind of EP type magnetic ferrite magnetic core, be specifically related to the manufacture of a kind of EP type magnetic ferrite magnetic core Method.
Background technology
Existing FERRITE CORE product is widely used in high frequency electronic switch transformator, energy-saving lamp electronic commutator, LED Lighting electronic constant current source field；In order to overcome the easy magnetically saturated inherent shortcoming of FERRITE CORE, typically use at magnetic core center pillar Grind the air gap of 0.10-2.0mm, to increase the magnetic resistance of magnetic circuit, it is to avoid the magnetic flux under big electric current and direct current biasing environment is saturated Phenomenon；Universal magnetic core such as EE, EC, EFD, RM can use high efficiency belt through-type air gap grinder to grind continuously, but It is that EP type magnetic core limit foot three bread encloses center pillar, grinds center pillar and can only put mill center pillar one by one by batch (-type), need manual operation bistrique, effect Rate is the lowest, and significantly improves the production cost of EP type magnetic core.
Summary of the invention
This patent is for problems of the prior art, it is provided that the manufacture method of a kind of EP type magnetic ferrite magnetic core, The center pillar end face of EP type magnetic ferrite magnetic core can be made all to be ground to man-hour adding, grinding process can with process common magnetic Core (EE, EC, EFD, RM) is identical, it is not necessary to other techniques of otherwise designed, and this method is greatly improved process velocity, it is not necessary to manually grasp Make, do not interfere with other performances of EP magnetic core simultaneously.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: a kind of EP type magnetic ferrite magnetic core Manufacture method, the process that grinds of EP type magnetic ferrite magnetic core uses belt through-type grinding machine equipment, EP type soft magnetic ferrite The limit foot opening direction of magnetic core is consistent with passing through type grinder equipment upper conveyor belt direction of advance and utilization is arranged on passing through type grinder On air gap emery wheel the center pillar of EP type magnetic ferrite magnetic core is carried out grinding, be arranged on the air gap emery wheel of passing through type grinder Polishing width slightly larger than the diameter of center pillar of EP type magnetic ferrite magnetic core.
The invention has the beneficial effects as follows: use the center pillar of this method grinding EP type magnetic ferrite magnetic core, EP type can be made The center pillar end face of magnetic ferrite magnetic core is all ground to adding man-hour, grinding process can with processing common magnetic core (EE, EC, EFD, RM) identical, it is not necessary to and other techniques of otherwise designed, this method is greatly improved process velocity, it is not necessary to manual operation, the most not Influence whether other performances of EP magnetic core.
Detailed description of the invention
Below in conjunction with embodiment, the detailed description of the invention of the present invention is further described.
The manufacture method of a kind of EP type magnetic ferrite magnetic core, the process that grinds of EP type magnetic ferrite magnetic core uses skin Before band passing through type grinder equipment, the limit foot opening direction of EP type magnetic ferrite magnetic core and passing through type grinder equipment upper conveyor belt Entering direction unanimously and utilizes the air gap emery wheel being arranged on passing through type grinder to grind the center pillar of EP type magnetic ferrite magnetic core Cutting processing, the polishing width of the air gap emery wheel being arranged on passing through type grinder is slightly larger than the straight of the center pillar of EP type magnetic ferrite magnetic core Footpath.
When using said method to manufacture EP type magnetic ferrite magnetic core, the middle styletable of EP type magnetic ferrite magnetic core can be made Face is all ground to adding man-hour, and grinding process can be identical with processing common magnetic core (EE, EC, EFD, RM), it is not necessary to sets separately Counting other technique, this method is greatly improved process velocity.EP magnetic core after processing can leave one and sand on the foot of limit simultaneously The groove that wheel width is identical, decreases the magnetic flux cross section of limit foot, owing to the foot cross section, limit of EP type magnetic core is wanted than center pillar magnetic flux cross section Greatly, as long as therefore foot magnetic flux cross section in limit would not have influence on other performances of EP magnetic core not less than center pillar magnetic flux cross section.
For a person skilled in the art, still the technical scheme described in foregoing embodiments can be repaiied Change, or wherein portion of techniques feature carried out equivalent, all within the spirit and principles in the present invention, that is made any repaiies Change, equivalent, improvement etc., should be included within the scope of the present invention.
