Specific embodiment
Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As shown in Figure 1-3, a kind of magnetic ball blank forms whole set of die, including big side plate 2, material is 12 molybdenum vanadium mold of chromium
Steel, the big side plate 2 be spaced it is opposite disposed there are two, be fitted and fixed in the middle part of the medial surface of each big side plate 2 by caulking groove 6
There is former side plate 3, the medial surface of two former side plates 3 is equipped with semiellipse column chamber 301, two semiellipse column chambers
301 closures form cylindroid chamber, and the cylindroid is intracavitary to be placed with seaming chuck 4 and push-down head 5, and the both ends of the big side plate 2 are equal
The retention bead 201 that the oriented inner vertical of integrated setting extends, between the retention bead 201 and the end of former side plate 3
Clamping fixed has small side plate 1, and small side plate 1 is 70 manganese steel.
The ratio between the long axis of the cylindroid chamber and short axle are 6:5.
The cylindroid cavity wall is shiny surface, and seaming chuck 4 and push-down head 5 and cylindroid chamber shape are coincide, it is described on
The sum of 5 height of pressure head 4 and push-down head is identical as the height of cylindroid chamber, is conducive to seaming chuck 4 along cylindroid chamber and moves down compression
Powder.
The height of the seaming chuck 4 is twice of 5 height of push-down head, and cylindroid is intracavitary, and there are abundant spaces to fill Nd-Fe-B powder
Material, and half elliptic groove, two half elliptic groove closeds are equipped on the end face that is in contact with push-down head 5 of seaming chuck 4
At shaping mold cavity 7, so that powder is pressed into chondritic blank.
Meanwhile also disclosing a kind of production method of magnetic ball blank molding whole set of die, including following operating procedure:
S1: assembly mold will be fixed with the opposed two sides for being placed on push-down head 5 of two big side plate 2 of former side plate 3, under
Half elliptic groove on pressure head 5 is upward, and two big side plate 2 is promoted inwardly and is drawn close, is fixed later using small side plate card gold
Between 3 end of retention bead 201 and former side plate of big side plate 2, two big side plate 2 is fixed, so that former side plate 3
The closure of semiellipse column chamber 301 of inside forms cylindroid chamber, and upper and lower size is identical；
S2: the powder for weighing up weight is imported the intracavitary portion of cylindroid by filler；
S3: compacting, the half elliptic groove that seaming chuck 4 is put into the intracavitary portion of cylindroid and seaming chuck 4 is downward, confirms errorless
Unitary mould is transferred in press afterwards, starts press, seaming chuck 4 is completely forced into cylindroid is intracavitary, the pressure of press is
150T, press binder speed are 1cm/s, then take out mold to powder oriented moulding by magnetic field；
S4: demoulding first splits two big side plate 2 to both sides, then small side plate 1 is removed to both ends, gently takes away
Pressure head 4 takes out the magnetic ball blank in shaping mold cavity 7, is sent into sintering in sintering machine, because of the contraction of magnetic ball different directions after coming out of the stove
