The specific embodiment
Shown in Fig. 1～7, Fig. 1 and Fig. 2 express two kinds of more representative ultrasonic bar forms that shake of single, double oscillator flexural vibrating ultrasound rod.
In Fig. 1, ultrasonic transducer 1 and luffing bar 2 are combined into the transducer assemblies A of a wavelength (1 goes into), and it is perpendicular to expanding the preposition metal of the power rod 3 that shakes, and by the front end face of luffing bar 2, closely kiss is connected to the place, an autocratic plane of 3 nodal point Q position, center; Expand the shake length wavelength (1 goes into) just in time of rod 3 of the preposition metal of power, its excellent central point Q just in time is half-wave (1/2 goes into) node position, say with regard to pole, its diameter is gone into scope in ￠≤1/4, and it is forms such as positive square rod, sq.rd, polygon rod that the rod 3 that the preposition metal of expansion power can be shaken is as required made sectional area; Expanding shake rod 3 of the preposition metal of power is connected with ultrasonic preposition functional bar head 5, a wherein excellent end face is provided with helical hole 6, can be linked to contact-making surface 4 by plug into screw rod and metal rod 3 the front end face that shakes, make the center longitudinal axis of 3,5 rod bars tightly be in one and move towards on the straight line;
In Fig. 2, ultrasonic transducer body assembly and compound mode thereof, dimensional parameters is all with identical shown in Fig. 1, on this basis, add a transducer assemblies A1 again, transducer 1-1 and luffing bar 2-1 are combined into the transducer assemblies A1 of 1 wavelength (1 goes into), its luffing bar 2-1 front end face with expand the preposition metal of power and shake the rear end face tight connecting of rod 3 in 7, and be in together on the excellent bar center longitudinal axis, make A, A1 two transducer assemblies are orthogonal, closely kiss is connected on the preposition metal bar 3 of expansion power simultaneously, and the distance that two places are right after between face Q and 7 is 1/2nd wavelength (1/2 goes into).No matter be among Fig. 1 or Fig. 2 the ultrasonic transducer combination with expand the shake fluid-tight engagement mode of rod 3 of the preposition metal of power, can adopt mechanical force tightly to overlay or adopt the screw rod of plugging into closely to link between the two.
Fig. 3～four schematic diagrames such as Fig. 6 expresses four kinds of ultrasonic bar forms that shake of many oscillators flexural vibrating ultrasound rod.
In Fig. 3, body assembly and compound mode thereof, dimensional parameters are all with above-mentioned shown in Figure 1 identical, on this basis, add transducer assemblies A2 again, this A2 is the transducer assemblies of 1 wavelength (1 goes into) of ultrasonic transducer 1-2 and luffing pavilion 2-2 combination, the front end face of its luffing bar 2-2 with expand the shake center nodal point Q of rod 3 of the preposition metal of power, being in the tight kiss in an autocratic plane connects, make A1, A2 two transducer assemblies exist together on the central axis direction, while closely kisses and meets 3 Q place, and shakes excellent 3 perpendicular to expanding the preposition metal of power simultaneously.
In Fig. 4, body assembly and compound mode thereof, dimensional parameters are all identical with above-mentioned Fig. 2 and comprehensive combination shown in Figure 3.Group constitutes one and has three ultrasound transducer assemblies, i.e. A1, A2, A3, and wherein the luffing bar 2-3 front end face of A3 becomes with rod 3 one end faces that shake spool vertically closely to be connected on the contact-making surface 7, makes A3 and homoaxial transducer assemblies A1, A2 orthogonal.
Fig. 5 and Fig. 6 are respectively to expand the extension that rod 3 and ultrasonic preposition functional bar head 5 center longitudinal axis directions form of shaking of the preposition metal of power, and the direct sight line of seeing with eyes constitutes the schematic diagram of same y direction.Fig. 5, shown in Figure 6ly respectively have simultaneously perpendicular to rod 3 four ultrasound transducer assembly A1, A2, A3, A4, their luffing bar front end face is all closely kissed and is connected on four autocratic planes at excellent 3 Centroid Q places, there is the biconjugate ultrasound transducer assembly to constitute the y direction straight line respectively, constitutes orthogonal relation between mutually other in addition two ultrasound transducer assemblies.The comprehensive function system that also has A5 to have five ultrasound transducer assemblies except that having A1, A2, A3, A4 shown in Figure 6, its body assembly dimensional parameters and group structure mode are all set forth identical with preceding all.
Through to Fig. 1～6 elaboration shown in totally six views, specific and comprehensive group structure and the key parameter feature of having described flexural vibrations type ultrasonic bar of the present invention clearly stated the realization approach of technical solution of the present invention clearly through comprehensive.
Flexural vibrations type ultrasonic bar of the present invention, its ultrasonic rod refers to and expands the shake characteristic that is combined into the rod shape of rod 3 and ultrasonic preposition functional bar head 5 of the preposition metal of power, its rod can be real plug, can be the hollow rod, can be the real core of part and the rod of part hollow, make into which kind of situation, should be to produce actual needs, the needs that have produce longitudinal wave, the needs that have produce lateral wave, vertical and the lateral wave proportioning coexistence of the needs that have, the liquid phase that needs ultrasonication that has flows or the like, can make according to need.Because the needs that make, 3,5 liang of former screw rods of plugging into of rod connect the screw rod of plugging into of end face 4, can make 3,5 liang of rods into and directly concern that by inside and outside screw hole between them connected mode realizes connecting.
In the present invention, the suitable structural parameters shape of Frequency for Ultrasonic Energy Transducer, luffing bar etc. in the adjustment group structure, supersonic frequency can be made into the frequency values at different levels between the 10KHZ to 100KHZ, its power that alone singly props up component system can be made into the performance number between the 10W to 10KW, in order to adapt to the needs of production and scale.
Many oscillators flexural vibrating ultrasound rod of the present invention, the main shear wave (as shown in Figure 3) that can produce obvious great power, if ultrasonic preposition functional bar head 5 is inserted in the liquid phase material system that is applied, according to producing needs, can carry out cavitation effect effects such as homogenizing, dispersion, the extraction of animals and plants effective ingredient, antiscaling, descaling, emulsification and cleaning effectively.
And for example above-mentioned Fig. 1 and shown in Figure 2 be respectively single, double oscillator flexural vibrating ultrasound rod, mainly can produce the obviously shear wave and the compressional wave of great power respectively, if it is installed in the plastic processing of ultrasonic extrusion molding and the extruding conveying production of pipeline slurry fluid, effect is remarkable.In Fig. 7, traditional one-to-two extrusion molding road M is shunted on the position 8 outside wall, the recessed dress of a moderate size position 9 is set; With the preposition metal of expansion power of flexural vibrations type ultrasonic bar of the present invention shake excellent 3 front end faces closely adorn insert 9 places (the extrusion molding pipeline M dividing walls here outer 8, replaced the ultrasonic preposition functional bar head 5 in the original structure), make the preposition metal of expansion power of the ultrasonic system rod 3 that shakes produce the longitudinal waves of launching, act on flowable materials in the pipe forcefully by pipeline shunting place rigid material, can make the slurry flow optimized, freely suitable, drag reduction, acceleration, evenly, polymer become a useful person rub thin, overcome fragility, energy-conservation.
If apply the present invention to welding, will bring into play powerful ultra-sonic welded advantage, thereby expand out a brand-new ultra-sonic welded advanced subject, future is considerable.
