Description
Technical field
The utility model relates to civil blast perforation parts and manufactures field, and specifically, the utility model relates to a kind of cavity liner spinning apparatus.
Background technology
Modern perforation is the principle that adopts efficient energy-collecting explosion, and the blast cumulative action of cavity liner is more and more subject to various countries researcher's attention.The Mohaupt effect of cavity liner is due to strong compressed metal after the shock wave arrival Types of Medicine cover of blast generation, one powerful metal jet that cover infinitesimal is formed to axis direction motion rapidly.Cavity liner is the carrier as Mohaupt effect energy with material, and its performance directly affects the quality of jet quality, as jet density, effluxvelocity and solid jet length etc.The patent No. is 201310644292.8 " cavity liner, perforating charge cartridge case and super deep penetrating charge ", discloses a kind of typical structure of cavity liner.
In existing cavity liner manufacture field, mostly adopt spin-on process to manufacture cavity liner, the raw material that spinning is manufactured cavity liner employing is metal dust, and metal dust is stressed compacting in spinning mold, forms the revolving parts with mold shape and size.But be trickle dusty material owing to suppressing raw material in prior art, a lot of tiny powder particle diameters are also less than die clearance, like this in the time of mould dress powder, just must have tiny metal dust in pipetting the whole courses of work such as cavity liner when cavity liner spinning and on die and drop between the mould rotating hole matching at spinning body diameter and body diameter, short so dozens of minutes, long several hours, just there is folder powder phenomenon, press from both sides dead phenomenon.Occur, after these situations, must cleaning out mould, reinstall debugging and make again, affect formed precision and operating efficiency.
utility model content
Technical problem to be solved in the utility model is to provide a kind of preventing and is pressed from both sides dead cavity liner spinning die by tiny metal dust in spinning process.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cavity liner spinning apparatus, comprise fixing inner chamber, rotating cavity die and drift, described rotating cavity die is placed in fixing inner chamber, drift be positioned at rotating cavity die same axis above, the external cylindrical surface of described rotating cavity die is provided with groove.
Described groove is distributed on the outer surface of rotating cavity die.
Described groove is the grooved of straight trough, helicla flute or other shapes.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Cavity liner spinning apparatus of the present utility model utilization is distributed on the groove on die external cylindrical surface, groove is distributed on the outer wall of die body, make the metal dust that enters die clearance in rotary course, constantly focus in the groove on the face of cylinder and fall, drop out mould fit clearance.Solve like this folder powder problem in mould spinning process, avoid the running accuracy of spinning die to be added the interference of powder, improve the concentricity of cavity liner product, the wearing and tearing of powder to mould are reduced, extend the service life of mould, the phenomenon of having avoided frequent cleaning mould holder powder, has improved production efficiency.
Brief description of the drawings
Mark in the each accompanying drawing of this description expressed content and figure is made to brief description below:
Fig. 1 is the structural representation of cavity liner spinning apparatus;
Fig. 2 is the front view of spinning die in Fig. 1;
Fig. 3 be in Fig. 2 A to cutaway view;
Mark in above-mentioned figure is: 1, fixing inner chamber; 2, cavity liner part; 3, rotating cavity die; 4, drift; 5, groove.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail as effect and the operation principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
As shown in Figure 1, when spinning, rotating cavity die 3 is arranged in the rotating hole in the fixing inner chamber 1 of mould, rotary gap between rotating cavity die 3 and fixing inner chamber 1 generally, between 0.006mm-0.035mm, adds metal dust compound in the conical cavity of rotating cavity die 3 before rotation compacting.When spinning, rotating cavity die 3 is by power driven rotary, drift 4 is descending above, the acting in conjunction that the metal dust compound that is arranged in rotating cavity die 3 cone-shaped cavities is subject to the axial compressive force of rotary centrifugal force and drift 4 conical surfaces depresses to the taper revolving parts with mold shape and size--cavity liner part 2, then drift 4 risings are backed out, spinning die rises to work top, the artificial cavity liner part 2 that takes out the powder compaction with certain density and intensity, such part pressing process completes.
As shown in Figure 1, automatic spinning die when work 180-800r/min moving up and down of compacting and depanning that rotatablely move, the raw material of compacting is trickle dusty material, and rotary gap between rotating cavity die 3 and fixing inner chamber 1 is generally between 0.006mm-0.035mm, a lot of tiny powder are also little more a lot of than die clearance, just will inevitably occur like this in gap that the raw material fine-powder in cavity liner part 2 drops between rotating cavity die 3 and fixing inner chamber 1 in the charging of mould, spinning, discharge process.As shown in Figure 2,3, on rotating cavity die 3 cylindrical outer surfaces, be uniformly distributed four straight flute 5, in the time that rotating cavity die 3 rotates, drop and under the effect of the powdered metal particles in gap in frictional force, constantly focus in groove 5 between rotating cavity die 3 and fixing inner chamber 1, then fall and drop out rotation fit clearance.The metallic particles in die clearance that drops so just can not cause folder powder, press from both sides dead phenomenon.Above-mentioned groove 5 is the grooved of straight trough, helicla flute or other shapes, and the setting of groove also helps the heat radiation of rotating cavity die 3.
Below the embodiment of the groove 5 that provides of inventor, so that utility model is further explained to explanation.
Embodiment 1:
Groove 5 on described rotating cavity die 3 and body external cylindrical surface is the grooved of four circumference uniform distributions, and grooved length is 50mm, width 10mm, degree of depth 1.0mm.
Embodiment 2:
The grooved of groove 5 Wei Sange garden Zhou Junbu on described rotating cavity die 3 and body external cylindrical surface, grooved length is 60mm, width 20mm, degree of depth 0.8mm.
Embodiment 3:
Groove 5 on described rotating cavity die 3 and body external cylindrical surface, grooved is the helicla flute of 30 ° of symmetrical double ends, width 20mm, degree of depth 0.6mm.Lift angle is 40 °, and double end dextrorotation is highly 60mm.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
