Abstract
An electroacoustic ring permanent magnet molding die comprises a base plate, lateral plates, a cover plate, a fixed arch pressure head, a movable arch pressure head, a cylinder core and a ring arch pressure head, wherein both the lateral plates and the fixed arch pressure head are fixedly connected with the base plate; the movable arch pressure head or the ring arch pressure head is placed in an extruding groove formed by the base plate and the lateral plates; the cover plate is placed on the upper surface of the lateral plates, the fixed arch pressure head, the movable arch pressure head or the ring arch pressure head; an end surfaces at one end of the fixed arch pressure head and the movable arch pressure head are semi-circular arc grooves; and the middle part at one end of the ring arch pressure head is a semi-circle lug. During the manufacturing process of permanent magnets, with adoption of a manner of twice powder weighing and twice compressions, the electroacoustic ring permanent magnet molding die can reduce fashioned powder by 20-50%, save production cost, effectively reduce labor intensity, and at the same time solves the problem about sintering difficulty caused by over-heavy large-specification cylinder permanent magnets in the prior art.
Description
Technical field
The utility model relates to a kind of electroacoustic circular ring-shaped permanent-magnet forming die.
Background technology
Electroacoustic circular ring-shaped permanent-magnet body, the conventional mode of production is that direct pressing becomes cylinder, then adopts the mode of drawing the hole to be processed into annulus, the product of this mode to some large specifications brings certain difficulty to sintering, simultaneously also waste a big chunk material, production cost is high, and labour intensity is large.
Summary of the invention
It is low that the purpose of this utility model just is to provide a kind of production cost, can reduce the electroacoustic circular ring-shaped permanent-magnet forming die of labour intensity.
electroacoustic of the present utility model circular ring-shaped permanent-magnet forming die, comprise base plate, side plate, cover plate, fixing arc pressure head, the adjustable arc pressure head, cylindrical core and annulus arc pressure head, side plate, fixedly the arc pressure head all is fixedly connected with base plate, adjustable arc pressure head or annulus arc pressure head are placed in the squeezing groove that base plate and side plate surround, cover plate is placed on side plate, fixing arc pressure head, the upper surface of adjustable arc pressure head or annulus arc pressure head, fixedly an end end face of arc pressure head and adjustable arc pressure head is the semicircular arc groove, be the semicircle projection in the middle part of one end of annulus arc pressure head.
Electroacoustic of the present utility model circular ring-shaped permanent-magnet forming die, during use, first annulus arc pressure head is placed in the squeezing groove that base plate and side plate surround, place the permanent magnet powder between the semicircle projection of the semicircular arc groove of fixing arc pressure head and annulus arc pressure head, cover cover plate, push annulus arc pressure head by forcing press, form the semicircular ring permanent magnet; Withdraw from afterwards annulus arc pressure head, put into cylindrical core in formed semicircular ring permanent magnet, the adjustable arc pressure head is placed in squeezing groove, and add the permanent magnet powder between the semicircular arc groove of cylindrical core and adjustable arc pressure head, with forcing press Compressive activities arc pressure head, after completing extruding, withdraw from adjustable arc pressure head and cylindrical core, namely form the circular ring-shaped permanent-magnet body.In circular ring-shaped permanent-magnet body extrusion process, carry out under certain magnetic field condition.
Electroacoustic of the present utility model circular ring-shaped permanent-magnet forming die, in carrying out circular ring-shaped permanent-magnet body production process, claim powder by twice, the mode of twice compacting, can reduce the moulding powder and drop into 20-50%, save production cost low, and can effectively reduce labour intensity, solved simultaneously the sintering difficult problem that in the prior art, large specification cylinder permanent magnet preponderance causes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
a kind of electroacoustic circular ring-shaped permanent-magnet forming die, comprise base plate 1, side plate 5, cover plate 3, fixedly the arc pressure head 2, adjustable arc pressure head 7, cylindrical core 4 and annulus arc pressure head 6, side plate 5, fixedly arc pressure head 2 all is fixedly connected with base plate 1, adjustable arc pressure head 7 or annulus arc pressure head 6 are placed in the squeezing groove that base plate 1 and side plate 5 surround, cover plate 3 is placed on side plate 5, fixedly the arc pressure head 2, the upper surface of adjustable arc pressure head 7 or annulus arc pressure head 6, fixedly an end end face of arc pressure head 2 and adjustable arc pressure head 7 is the semicircular arc groove, be semicircle projection 8 in the middle part of one end of annulus arc pressure head 6.
