The pressing and forming mould for the neodymium-iron-boron cylinder comprises a lower forming end head, an upper pressing head and four side plates, wherein the lower end face of the upper pressing head and the upper end face of the lower forming end head are respectively manufactured into a single or a plurality of symmetrical semicircular concave faces, and a single or a plurality of cylindrical die cavities are formed when the upper pressing head and the lower forming end head are pressed. The mould disclosed by the utility model is simple to manufacture, is small and exquisite, is convenient for operating personnel to operate and has high working efficiency; more than 10 crude blanks can be pressed at each time; powder after being loaded can be evenly shaken by manpower, so that the powder in the die cavities is uniform; blanks after being sintered form a cylindrical shape by designing the shapes of the die cavities; and when a magnetic field is oriented, the orientation of the powder cannot be influenced by the upper pressing head clamped at the side plates.
Description
Technical field
The utility model belongs to the technical field of powder compacting compacting tool set, particularly relates to the cylindrical press-moulding die of a kind of neodymium iron boron.
Technical background
Neodymium iron boron permanent magnet, particularly sintered NdFeB permanent magnet have the excellent magnetism ability, as in performances such as remanent magnetism, coercivity, magnetic energy products very high performance being arranged all, are widely used in medical treatment, communication, electric equipment, instrument, motor, mechanical aspects.Making sintered Nd-Fe-B permanent magnet many now is main with PM technique, and manufacture process comprises batching, melting, hydrogenation treatment, powder process, compression moulding, sintering, timeliness.The purpose of wherein suppressing; Utilize the compacting of press exactly; Make Magnaglo have certain shape, size, pressed density and intensity, carry out the processing of subsequent processing then, the flow process of suppression process generally comprises steps such as claiming powder, charging, orientation, matched moulds compacting, the demoulding.The compacting quality influence the blank dimension of follow-up sintering, the magnetic property to magnet also has certain influence simultaneously.Mostly neodymium iron boron compacting at present is square or the cylinder that volume is bigger, because the uniformity coefficient of powder is little to the green compact influence that is pressed in the big die cavity of volume, but few for filling amount; The uniformity coefficient of powder is bigger to the size impact of final products in the product that body diameter is little, die cavity, and the fragile compacting when the demoulding of some compacting tool sets; Influence product percent of pass; The manufacturing of mould is complicated, is unfavorable for that the operator operates, and has also influenced the efficient of producing.
The utility model content
To the technical problem of above-mentioned existence, the utility model provides a kind of neodymium iron boron cylindrical press-moulding die.
To achieve these goals, the technical scheme of the utility model is:
The utility model is made up of compacted under termination, seaming chuck, long side plate and short side plate; The upper surface of the lower surface of said seaming chuck and compacted under termination is processed single or a plurality of semicircle concave surfaces of symmetry respectively, has formed single or a plurality of cylindrical mold cavities when seaming chuck and the pressing of compacted under termination.
Two end face centers of said seaming chuck are equipped with the steel ball pearl that has the spring extruding, and the ball pearl is given prominence to end face, has the semi-circular groove that cooperates with the ball pearl on two short side plates, finish the back in compacting and block seaming chuck through the ball pearl.
The cross section of the cylindrical mold cavities behind the said matched moulds is oval, and major axis compares at 1: 1.2 with minor axis length.
The beneficial effect of the utility model is:
The manufacturing of the utility model mould is simple, small and exquisite, and operating personnel are convenient to operation, and high efficiency can be suppressed the green compact more than 10 at every turn, can shake up through manual work behind the dress powder, makes the interior powder of die cavity even; Through the shape of design die cavity, make the blank behind the sintering become cylindrical; During magnetic field orientating, the seaming chuck that is stuck in side plate can not influence the orientation of powder.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the preceding schematic cross-section of compacting.
Fig. 3 is for suppressing the schematic cross-section after finishing.
Among the figure: 1. die cavity, 2. short side plate, 3. long side plate, 4. seaming chuck, 5. semicircle groove, 6. compacted under termination, 7. ball pearl, 8. spring.
The specific embodiment
According to accompanying drawing and embodiment the utility model is elaborated below.
Embodiment: as shown in Figure 1; The utility model is formed shaping mold cavity 1 by compacted under termination 6, seaming chuck 4 and two long side plates 3 with short side plate 2; Compacted under pressure head 6 places die cavity 1 bottom; The upper surface of the lower surface of seaming chuck 4 and compacted under termination 6 is processed single or a plurality of semicircle concave surfaces of symmetry respectively, has formed single or a plurality of cylindrical mold cavities 1 when seaming chuck 4 and 6 pressings of compacted under termination.The seaming chuck 4 of the pressure head compacting tool set of press is pressed into when becoming a plane with each side plate, and compacting is accomplished.
As shown in Figures 2 and 3; The steel ball pearl 7 that has spring 8 extruding is installed at 4 two end face centers of said seaming chuck; Ball pearl 7 prominent end planes have the semi-circular groove 5 that cooperates with ball pearl 7 on two short side plates 2, finish the back in compacting and block seaming chuck 4 through ball pearl 7.The cross section of the cylindrical mold cavities 1 behind the said matched moulds is oval, and major axis compares at 1: 1.2 with minor axis length.
The course of work of the utility model:
In four side plates and compacted under termination 6 formed cavitys, put into the powder of wanting moulding, after seaming chuck 4 is put in die cavity 1 top, through the outstanding ball pearl 7 of spring 8 extruding; Be stuck in two short side plates, 2 tops, as shown in Figure 2, the mould that assembles is placed between press two cartridges; Two cartridges extruding, the two long side plates 3 that have coil, and logical magnetic field is orientated powder, in the orientation process; The pressure head of Magnetic field press compacting seaming chuck 4,, as shown in Figure 3 up to seaming chuck 4 upper surfaces with till the end face of each side plate becomes a plane; After compacting finished, the pressure of decorporating took out mould; Manually split four side plates and seaming chuck 4, the green compact cross section after the compacting is oval, and green compact become regular cylinder behind sintering.
Seaming chuck 4 described in the utility model is processed with the compacted under termination low alloy of 6 usefulness permeabilities, and four side plates are combined into shaping female mold through draw-in groove, and the magnetic field cartridge through the pressing under magnetic field press during compacting mobile reaches the purpose that compresses side plate.The short side plate 2 usefulness permeabilities low alloy parallel with magnetic direction processed; The long side plate 3 usefulness permeabilities high alloy vertical with magnetic direction processed; Mainly be the pressure head compacting tool set seaming chuck 4 movably through press during compacting, come the powder in the compression moulding die cavity 1.Before the compacting, seaming chuck 4 is stuck on the short side plate 2 through steel ball pearl 7, directly is not pressed on the powder, helps abundant orientation.
