Ultrasonic impact treatment device

Ultrasonic impact treatment device(Aging Treatment System) Products Major technical performance parameterGenerator size: 380&times220&times200mmGenerator weight: 8kgsPower supply: 220V,50HZ, 5AWorking frequency: 20kHzMax power: 500W; 10%--100% adjustableMain size: length 450mmWeight: 4 KGSImpacted object shape: Impact needle or Impact stick Ultrasonic Impactor illustrationPrinciple of Ultrasonic aging impactors to improve the strength of welding joint: Ultrasonic impactor makes use of high power ultrasonic to force the instrument to impact on the metal surface with frequency of 20,000 times/s or more. Metal surface induces great plastic deformation by impacting of ultrasonic with high frequency, high efficiency, high power and great focus on energy. When the original stress field is affected altered will induce a certain value of compressive stress and the joint of impacted place is made strengthen. Ultrasonic generator connects the transducer inside by cable. Output of transducer is connected with booster. And at end side of booster an impacting needle is installed Ultrasonic generator transforms the commercial electric power to A.C of high frequency with high voltages and transports the current to transducer. The ultrasonic transducer transforms the electric energy to the mechanical energy, which is sound energy of ultrasonic. Its main evidence is the longitudinal reciprocating expansion movement. The expansion frequency is equal to the generator's A.C frequency and expansion amplitude in about 10 microns. One of booster function is enlarge the transducer amplitude exceeding 100 microns. In the other hand, it exerts impact force full on the needle, force it rushes in high speed. The energy transfers to the welding line after the needle impacting on the work piece to achieve the effect of internal stress elimination. Impacting needle rebounds after receiving the work piece's reaction, it excites again when it returns to the high frequency vibrating booster, and it strikes the welding line again. Repeating this cycle many times it accomplishes the work. CharacteristicHigh power, high impact effectHigh reliability, long using lifeLight weight, portable, easy to operateExcellent designation, wide use scopeDistinctly save energy, reduce charge. Efficacy1 .Cause residual stress of pulling in the metal welding line surface layer changed into compressive stress. Significantly increase the fatigue life of metal structure 2. Change the grain layer on metal surface into plastic deformation layer to improve strength and hardness of metal surface layer significantly. 3. Improve the weld toe geometric, reduce the stress focus.
