Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of detailed description of the invention.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As depicted in figs. 1 and 2, comprise according to the concrete structure of the manufacturing installation of the neodymium iron boron spheroid of the utility model detailed description of the invention: form magnetic conductive board 1 and the pasting board 2 of die cavity, and can relative sliding be arranged on upper punch 3, the bottom punch 4 in this die cavity.Wherein, the opposite face of upper punch 3 and bottom punch 4 offers respectively the shaping groove of semielliptical shape, relative sliding is to pressing in die cavity for upper punch 3 and bottom punch 4, and the neodymium iron boron powder that makes to pour in die cavity forms spheroid pressed compact, completes the shaping work of neodymium iron boron spheroid.
Wherein, magnetic conductive board 1 is for mutually detaining two that establish, the opposite face of two magnetic conductive boards 1 has respectively the multiple semi-cylindrical die face being arranged side by side, the both sides of this die face offer respectively pasting board groove, pasting board 2 is two, two magnetic conductive boards 1 are detained while establishing (two magnetic conductive boards 1 do not contact) mutually, and two pasting boards 2 are laid in respectively in the pasting board groove of two magnetic conductive boards 1.Now, the semi-cylindrical die face of two magnetic conductive boards 1 and the medial surface of pasting board 2 form multiple columniform die cavitys that are arranged side by side of the manufacturing installation of this neodymium iron boron spheroid jointly, and pass two magnetic conductive boards 1 and pasting board 2 is fixed by bolt.Cavity depth is greater than the vertical height of spheroid neodymium-iron-boron.
