Abstract
The utility model discloses an efficient rotating press mold, which comprises three coaxial turntables including an upper turntable, a middle turntable and a lower turntable, wherein stations in one-to-one correspondence are arranged on the upper turntable, the middle turntable and the lower turntable, an upper stamping mold is arranged on the upper turntable of the rotating press mold, a lower tamping mold is arranged on the lower turntable, a female mold is arranged on the middle turntable, mold cavities are uniformly distributed on the female mold, the mold cavity number on the female mold is N, and the N is a nature number greater than 2. The mold in each station consists of the upper stamping mold, the lower stamping mold, the female mold and a core rod. The forming rate of magnetic materials pressed by a rotating press is high, and the consistency of magnetic core products is greatly improved.
Description
Technical field
The utility model belongs to the special equipment of magnetic core forming method, relates in particular to a kind of efficient rotary press mould.
Background technology
Along with communication industry develops rapidly, the magnetic ferrite magnetic core demand that EP, EPO, RM type etc. are used for communication class significantly rises, and quality requirements such as homogeneity of product, high accuracy are also increasingly high.At present, FERRITE CORE generally adopts the dry powder forming method, uses RP rotary press equipment.Rotary press is on three coaxial turntables in upper, middle and lower, and 8 stations are arranged, the mould of each station by Shang Chong, Xia Chong, die, and core bar form.Rotate a circle every mold of press is accomplished a pressing cycle, and every mold of same time is in filling out in the processes such as powder, precompressed, pressurization, the demoulding of press compaction curve respectively.Disk rotates a circle, and adopts mould of a mould, can suppress 8 casting dies.To the present situation of market, be badly in need of a kind of former of FERRITE CORE efficiently to the sharp increase of communication class magnetic ferrite magnetic core demand.
Summary of the invention
To above-mentioned technological deficiency, the technical problem that the present invention need solve is to solve the low problem of FERRITE CORE ratio of briquetting.
The technical problem that the present invention need solve realizes through following technical scheme: a kind of efficient rotary press mould comprises three rotating disks in upper, middle and lower of concentric on three rotating disks in upper, middle and lower, being provided with station one to one; On top rotary table, be provided with upper trimming die; Lower rotary table is provided with down punch die, and turntable is provided with die, is laid with die cavity on the die; Die cavity number on the said die is N, and N is the natural number greater than 2.The mould of each station is made up of upper trimming die, following punch die, die and core bar.
Further: on above-mentioned efficient rotary press, described station number is more than or equal to 8, and the die cavity number on the said die is 2～10.The trueness error of said cavity depth is ± 0.02mm.Described upper trimming die, following punch die and die all are the axial symmetry designs.
Compared with prior art, above-mentioned this efficient rotary press mould comprises three rotating disks in upper, middle and lower of concentric, on three rotating disks in upper, middle and lower, is provided with station one to one; The rotary press mould is provided with upper trimming die on top rotary table, lower rotary table is provided with down punch die, and turntable is provided with die; Be laid with die cavity on the die; Described station number is N, and N is the natural number greater than 2, and the die cavity number on the die is corresponding one by one with the station number.This high-efficiency molding press can improve 2～10 times of shaping efficiencies, and this method one-mold multiple-member compacting has improved consistency of product.Promptly the ratio of briquetting of this rotary press compacting magnetic material is high, and the magnetic core product uniformity significantly improves.
Description of drawings
Fig. 1 is the utility model die structure diagram.
Specific embodiments
With reference to the accompanying drawing and the specific embodiment the utility model is described.
Like accompanying drawing 1, a kind of efficient rotary press mould comprises three rotating disks in upper, middle and lower of concentric; On three rotating disks in upper, middle and lower, be provided with station one to one, the rotary press mould is provided with upper trimming die on top rotary table, and lower rotary table is provided with down punch die; Turntable is provided with die 1; Be laid with die cavity 2 on the die 1, the die cavity on the said die several 2 is N, and N is the natural number greater than 2.Described station number is more than or equal to 8, and the die cavity on the said die several 2 is 2～10.The trueness error of said cavity depth is ± 0.02mm.Described upper trimming die, following punch die and die all are the axial symmetry designs.
Circulation output of the rotary press of the utility model >=8 station >=8 set products is behind the one mould N spare (like N=2 ~ 10), like 16 ~ 80 products of circulation output of 8 stations, 2 ~ 10 times of improved efficiencies.Among Fig. 1, N is 32 products of circulation output of 4,8 stations.This rotary press one-mold multiple-member forming technique has at first reduced equipment inputs such as press on the formed product cost, secondly reduce artificial the input, also reduces electric energy.The forming method of one-mold multiple-member is controlled better than the isotype precision that manys a product, isotype compacted products uniformity is significantly improved.
The above is a preferred embodiment of the utility model, is not breaking away under the design situation of the present invention, carries out any conspicuous distortion and replacement, all belongs to the protection domain of the utility model.
