Abstract
The utility model is related to a kind of mould, more particularly to a kind of to prepare the mould that footpath is orientated small column neodymium iron boron magnetic body.Feature is：Including：Seaming chuck, push-down head, it is characterised in that the lower surface of seaming chuck is evenly equipped with arc lower groove, push-down head have been evenly distributed in the upper surface arc lower groove corresponding with arc groove on seaming chuck.It is particularly suitable for the production that diameter is less than 3mm neodymium iron boron cylinders, the stability of small column can be effectively improved by directly changing performance structure in forming process, substantially increase the high remanent magnetism of material, high-coercive force, high energy product and reduce postorder processing cost, bring considerable economic benefit.
Description
Technical field
The utility model is related to a kind of mould, more particularly to a kind of to prepare the mould that footpath is orientated small column neodymium iron boron magnetic body
Tool.
Background technology
In traditional neodymium iron boron production technology, radial direction cylinder (is particularly below D3, radial direction cylinder needed for preparing：Magnetic force
The magnet cylinder that money is moved towards along radial direction) mould that uses, seaming chuck and push-down head opposite face be plane, mainly first will
Neodymium iron boron magnetic body is pressed into square, sintering, is cut into small side's bar according to magnet magnetizing direction with inside diameter slicer again after timeliness, then
It is rolled into small column with spheronizator again, but so not only time-consuming but also waste of materials again, it directly affects subsequent operation and add
Production cost.
Utility model content
The utility model purpose is to provide a kind of one kind for improving production efficiency to prepare footpath orientation small column neodymium-iron-boron
The mould of body.
Technical scheme is as follows：
The utility model includes：Including：Seaming chuck, push-down head, it is characterised in that the lower surface of seaming chuck is evenly equipped with lower arc
Connected in star, push-down head has been evenly distributed in the upper surface arc lower groove corresponding with arc groove on seaming chuck.
Further：The seaming chuck is radially at least provided with a upper arc groove, and push-down head is radially provided with recessed with upper arc
The dividing plate with arc convex is provided with the corresponding cell body of groove, cell body, the arc convex of dividing plate is corresponding with upper arc groove, upper arc
Groove releases magnetic.
Compared with prior art, the technology of the present invention effect includes：
Seaming chuck and push-down head opposite face are respectively equipped with corresponding arc groove, one-time formed pressure by the utility model
Neodymium iron boron small column is made, process has been simplified, cost has been saved, production efficiency is substantially increased.
The utility model realizes the multigroup neodymium iron boron small column of one-shot forming by increasing dividing plate, and production efficiency is doubled and redoubled.
Brief description of the drawings
Fig. 1 is pressure head combining structure schematic diagram above and below utility model；
Fig. 2 is the structural representation of utility model embodiment 2.

6, the arc convex on dividing plate 6 is corresponding with upper arc groove, and upper arc groove releases magnetic.
The course of work：Push-down head 2 (dividing plate has been fixed in the cell body of push-down head), magnetic conductive board 3, magnetic isolation plate 4 are assembled,
The NdFeB magnetic powder weighed up is poured into wherein, the seaming chuck 1 for having been provided with arc groove is put, is integrally placed to carry out on press
It is compressing, after the completion of shaping, magnetic conductive board 3 and magnetic isolation plate 4 are peeled off, seaming chuck 1 is removed, two row's neodymium iron boron magnetic body small columns is taken
Go out.
The utility model changes neodymium iron boron small column performance structure, is particularly suitable for diameter less than 3mm neodymium iron boron cylinders
The production of body.Suppressed for traditional square mould will be cancelled in radial direction small column forming process, be changed to radial oriented (take
To：The magnetizing direction of postorder) roundlet post mold suppressed, effectively improves the stability of small column, substantially increase material
The high remanent magnetism of material, high-coercive force, high energy product and postorder processing cost is reduced, bring considerable economic benefit.
Comparative example
Time：On April 25th, 2016
Batch：ST20160425
Customer demand roundlet column dimension：Φ 3*4 (magnet diameters：3mm magnet lengths：4mm)
Need weight：1.15kg
Pressing magnetic body square is carried out with traditional square mould, again by the magnetizing direction side of being cut into bar after having sintered, then
Again side round as a ball, peripheral milling.
Size after compressing sintering：68.5*41.7*53.7 (53.7 directions orientation)
Powder density：7.5g/cm3
Throw powder amount：1.15kg
Butt rule number：20*12*12=2880 bars
Classical prescription is round as a ball, peripheral milling obtains radial direction small column：2850 (have been lost：30)
Process is cumbersome and uniformity of properties of product are substantially reduced, and production efficiency is extremely low.
