Abstract
The invention discloses a kind of method for improving the up-to-standard rate of Double face grinding rare-earth permanent magnet ferrite ring magnet periphery, before ring magnet enters double-ended grinding machine grinding both ends of the surface, first with nylon ribbon lock ring on the periphery of ring magnet, the width of nylon ribbon is less than the thickness of ring magnet；Then enter grinding area together on track blade in company with ring magnet, do not allow the periphery of ring magnet directly to contact track blade so that being made periphery fall side or cutting spot by grinding force during advance；Finally use the both ends of the surface of diamond wheel grinding ring magnet.Beneficial effects of the present invention are：It is simple and easy, periphery quality can be effectively improved, improves product quality more than 30%.
Description
Technical field
It is mainly a kind of to improve Double face grinding rare-earth permanent magnet ferrite annular magnet the invention belongs to permanent magnetic ferrite field
The method of the up-to-standard rate of external disc.
Background technology
When magnet is fed, it is scrolled into from steel blade frame when being ground a kind of magnet both ends of the surface of circle with double-ended grinding machine
Enter；In motion process, contacted because grinding produces the external periphery of excitation with blade depths, magnet periphery of easily damaging, such as
Chip off-falling, spot, tooth print etc., magnet is scrapped because outward appearance is bad.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of raising Double face grinding rare earth forever
The method of the up-to-standard rate of magnetic ferrites ring magnet periphery.
The purpose of the present invention is completed by following technical solution.This raising Double face grinding rare-earth permanent magnet oxygen
The method of the up-to-standard rate of body ring magnet periphery, before ring magnet enters double-ended grinding machine grinding both ends of the surface, first use Buddhist nun
For imperial ribbon lock ring on the periphery of ring magnet, the width of nylon ribbon is less than the thickness of ring magnet；Then in company with annulus
Magnet enters grinding area together on track blade, does not allow the periphery of ring magnet directly to contact track blade so that advancing
During by grinding force make periphery fall side or cutting spot；Finally use the both ends of diamond wheel grinding ring magnet
Face.
Further, the nylon ribbon is knitted into band using nylon wire mechanism, and nylon fabric tape width is less than annular magnet
The thickness 4mm of body, nylon ribbon is taken to the length smaller 1-2mm than the circumference size of ring magnet, lock ring exists after suture connection
On ring magnet outer circumference surface.
Further, after the both ends of the surface of grinding ring magnet, nylon ribbon removes reuse.
Beneficial effects of the present invention are：It is simple and easy, can effectively improve periphery quality, improve product quality 30% with
On.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of the ring magnet of the present invention.
Description of reference numerals：Ring magnet 1, skive 2, track blade 3, nylon ribbon 4, grinding carriage axle 5, emery wheel
Frame 6.
Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：
As illustrated, this side for improving the up-to-standard rate of Double face grinding rare-earth permanent magnet ferrite ring magnet periphery
Method, rare-earth permanent magnet ferrite ring magnet both ends of the surface, including ring magnet 1, track blade 3, nylon are ground with double-ended grinding machine
Ribbon 4, double-ended grinding machine mainly include skive 2, grinding carriage axle 5 and grinding carriage 6.Enter Double End in ring magnet 1
Before grinding machine both ends of the surface, first with the lock ring of nylon ribbon 4 on the periphery of ring magnet 1, the width of nylon ribbon 4 is less than circle
The thickness of ring magnet 1；Then enter grinding area together on track blade 3 in company with ring magnet 1, do not allow ring magnet 1 outside
Disc directly contacts track blade so that being made periphery fall side or cutting spot by grinding force during advance；Finally use
Skive 2 is ground the both ends of the surface of ring magnet 1, and after the both ends of the surface of grinding ring magnet 1, nylon ribbon 4 removes repetition
Use.The nylon ribbon 4 is knitted into band using nylon wire mechanism, and the width of nylon ribbon 4 is less than the thickness 4mm of ring magnet 1
(wide or emery wheel can be contacted when being ground more than thickness, too small annulus precession is unstable).
Embodiment：1 diameter of ring magnet × internal diameter × thickness Ф 168 × Ф, 85 × 21mm, the width of nylon ribbon 4 are
17 mm.When ring magnet 1, which enters double-ended grinding machine, to be ground, nylon ribbon 4 contacts track blade 3, and will not damage ring magnet
1 outer circumference surface.The job step of the present invention is as follows：It is determined that the size of ring magnet 1 of end face need to be ground with double-ended grinding machine, if
Meter and customized nylon ribbon 4, nylon ribbon 4 is taken to the length smaller 1-2mm than the circumference size of ring magnet 1, suture connection
Lock ring is ground on the outer circumference surface of ring magnet 1 into double-ended grinding machine afterwards, and another use is removed after mill.
It is understood that it will be understood by those skilled in the art that technical scheme and inventive concept are subject to
The protection domain of appended claims of the invention should all be belonged to replacement or change.
