Description
Technical field
This utility model relates to a kind of permanent magnet and manufactures field, particularly relates to the heat pressing and molding mold of a kind of rare earth permanent magnet radiation ring.
Background technology
Rare earth permanent magnet radiation ring, particularly Re-Fe-B base rare earth permanent magnet material, the technique of its radiation ring forms typically via powder metallurgic method compacting, forms radially oriented annulus when compacting by producing the magnetic field of radiation, then again through vacuum-sintering molding.Owing to when powder is suppressed, being subject to the dual function of powder body and radiation field, molding is very difficult, and sintering qualification rate is low.
In recent years by studying discovery, the orientation of the crystal grain of Re-Fe-B rare earth permanent magnet can be produced impact by pressure, and the easy differently-oriented directivity of Re-Fe-B crystal grain is vertical with pressure direction.This utility patent devises a kind of mould for making Re-Fe-B base permanent magnet radiation ring under high temperature.
Utility model content
For solving the problem that background technology is mentioned, the utility model proposes following technical scheme:
The heat pressing and molding mold of a kind of rare earth permanent magnet radiation ring, including a columnar pressure cylinder, it is characterised in that: it is additionally provided with seaming chuck, push-down head and auxiliary pressure head in described pressure cylinder；
Described seaming chuck is cylindrical, and center is provided with a funnelform through hole, and seaming chuck external diameter mates with pressure cylinder internal diameter；
Described push-down head is cylindrical, and end diameter is less than the diameter of its body, and there is conical transition zone end to body diameter；The diameter that the end diameter of described push-down head catches up with pressure head through hole is suitable, and push-down head body diameter is less than pressure cylinder internal diameter so that form a die cavity between push-down head body and pressure cylinder inwall；
The axis of described seaming chuck, push-down head and auxiliary pressure head overlaps with pressure cylinder axis, and seaming chuck is arranged on pressure cylinder upper end, and the through hole of seaming chuck is inserted in the end of push-down head.
Described auxiliary pressure head is located at push-down head body surface, and its external diameter is equal to pressure cylinder internal diameter, and its internal diameter is equal to push-down head external diameter.
During use, pre-for the annular of high temperature preheating briquetting being enclosed within push-down head end, is filled in by push-down head in pressure cylinder, promote push-down head gradually, the end of seaming chuck packs in the through hole of seaming chuck；The pre-briquetting of high temperature seaming chuck, push-down head pressure under produce deformation, and move to body surface along push-down head conical transition zone.When push-down head end fully enters in seaming chuck through hole, the pre-briquetting of high temperature is subject to molded in the die cavity that pressure cylinder, push-down head, auxiliary pressure head three are formed.Upwardly assisting pressure head, the product of molding is assisted pressure head to release, and completes whole process.
This utility model simple in construction, can utilize the extruding of each pressure head cleverly, produces magnetic force to annular permanent magnets radially.
Accompanying drawing illustrates:
Fig. 1 is each structure disassembly diagram of the present utility model；
Fig. 2 is this utility model assembling figure.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below the utility model is described in further detail:
As shown in Figure 1-2, the heat pressing and molding mold of a kind of rare earth permanent magnet radiation ring, including a columnar pressure cylinder 1, in described pressure cylinder 1, it is additionally provided with seaming chuck 2, push-down head 3 and auxiliary pressure head 4；
Described seaming chuck 2 is cylindrical, and center is provided with a funnelform through hole, and seaming chuck 2 external diameter mates with pressure cylinder 1 internal diameter；
Described push-down head 3 is cylindrical, and end diameter is less than the diameter of its body, and there is conical transition zone end to body diameter；The diameter that the end diameter of described push-down head 3 catches up with pressure head 2 through hole is suitable, and push-down head 3 body diameter is less than pressure cylinder 1 internal diameter；
Described auxiliary pressure head 4 is located at push-down head 3 body surface, and its external diameter is equal to pressure cylinder 1 internal diameter, and its internal diameter is equal to push-down head 3 external diameter.
The axis of described seaming chuck 2, push-down head 3 and auxiliary pressure head 4 overlaps with pressure cylinder 1 axis, and seaming chuck 2 is arranged on pressure cylinder 1 upper end, and the through hole of seaming chuck 2 is inserted in the end of push-down head 3.
During use, pre-for the annular of high temperature preheating briquetting being enclosed within push-down head 3 end, is filled in by push-down head 3 in pressure cylinder 1, promote push-down head 3 gradually, the end of push-down head 3 packs in the through hole of seaming chuck 2；The pre-briquetting of high temperature seaming chuck 2, push-down head 3 pressure under produce deformation, and move to body surface along push-down head 3 conical transition zone.When push-down head 3 end fully enters in seaming chuck 2 through hole, the pre-briquetting of high temperature is subject to molded in the die cavity 5 that pressure cylinder 1, push-down head 3, auxiliary pressure head 4 three are formed.Upwardly auxiliary pressure head 4, the product of molding is assisted pressure head 4 to release, and completes whole process.
Below only some one exemplary embodiment of the present utility model is described by the mode of explanation, undoubtedly, for those of ordinary skill in the art, when not necessarily departing from spirit and scope of the present utility model, it is possible to by various different modes, described embodiment is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as the restriction to this utility model claims.
