Abstract
The invention discloses a production method of a NdFeB (Neodymium Iron Boron) radiation ring. The NdFeB radiation ring is produced by a radiation ring forming device. The production method comprises the steps of spreading magnetic powder in a gap between a female die outer sleeve and a mandrel, driving a transmission main shaft, a female die inner sleeve and the female die outer sleeve to rotate by a chain wheel mechanism to magnetize, pressing the mandrel through an upper pressing head after the completion of the magnetizing of the magnetic powder, moving the mandrel along a slot downwards, forming a magnetic ring, and then stopping rotating, taking out the upper pressing head to leave away from a cavity, and finally taking out the magnetic ring in the cavity under an ejection function of a hydraulic lifting cylinder. According to the production method of the NdFeB radiation ring provided by the invention, the magnetic energy product, the product consistency and square degree requirement of the radiation rings of different specifications can be ensured, the product percent of pass of the radiation rings can be greatly improved as well; meanwhile, the production efficiency can be greatly improved.
Description
Technical field
The present invention relates to a kind of neodymium iron boron radiation ring production method.
Background technology
In current neodymium iron boron industry radiation ring produce adopt be following several scheme:
1) D.C. magnetic field is equipped with special magnetic conductive loop
Namely, time shaping, under magnetic is in the effect in magnetic field always, aligns in pressing process and be not destroyed.
2) pulsed magnetic field magnetizing coil docking calculation
Namely, time shaping, the magnetic line of force that two coils are produced repels each other arrangement, utilizes coil to cross the magnetic field generation radiation field of edge part.
3) employing pulls moulding press molding mode
Namely the cartridge up and down pulling moulding press is utilized not only to suppress but also magnetize.
The objective shortcoming of prior art: first kind of way not easily produces comparatively large radiation field, and the degree of orientation is not high, radiation field and the magnet ring size of generation have comparatively Important Relations.Although second way radiation field is comparatively large, be conducive to improving the degree of orientation, magnetic is not always under magnetic fields, align during compacting and destroy to some extent, cause characteristic curve squareness bad, the dismounting of magnet ring is inconvenient in addition, production efficiency is low, and conforming product rate is low.The third mode is the same with the first, and generation radiation field and magnet ring size have comparatively Important Relations, and the product magnetic energy product that size is large does not reach requirement.
Summary of the invention
The object of the present invention is to provide a kind of conforming product rate of radiation ring high, the neodymium iron boron radiation ring production method of simultaneously also enhancing productivity.
Technical solution of the present invention is:
A kind of neodymium iron boron radiation ring production method, is characterized in that: adopt radiation ring forming device to produce; Described radiation ring forming device comprises the chain-wheel mechanism of driven by servomotor, chain-wheel mechanism is connected with transmission main shaft, transmission main shaft top is connected with former inner sleeve, be fixedly mounted with outside former inner sleeve and former overcoat, and the bottom of former overcoat is sleeved on outside former inner sleeve, the top of former overcoat is positioned at the top of former inner sleeve, and the lower diameter of former overcoat is greater than the upper diameter of former overcoat; In the top that plug is inserted into former overcoat and former inner sleeve, plug lower end is stretched in the groove on transmission main shaft top, in the form that can move up and down in groove; Arrange magnetic conduction pole in the upper outside of former overcoat, magnetic conduction pole overcoat dress solenoid, magnetic conduction pole and solenoid are packed on main frame floating beam; The seaming chuck be contained on main frame upper beam is set above former overcoat; Below chain-wheel mechanism, hydraulic lift(ing) cylinder is set;
During production, magnetic is sprinkling upon in the gap between former overcoat and plug, drive transmission main shaft, former inner sleeve, former overcoat to rotate by chain-wheel mechanism, magnetize, after magnetic magnetizes, core presses down by seaming chuck, core moves down along groove, and magnet ring is shaping, then rotates stopping, seaming chuck is deviate to leave die cavity, and magnet ring is deviate under hydraulic lift(ing) cylinder ejects effect in die cavity.
The present invention had both ensured the magnetic energy product of different size radiation ring, the consistency of product and squareness requirement, made again the conforming product rate of radiation ring significantly improve, and also significantly improved the efficiency of production simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
