28mm 30khz Ultrasonic welding transducer for longitudinal-torsional vibration

Parameter

Introduction

In many cases , the transducer is followed by a metallic booster whichensures a displacement amplification, due to its special shape (conical .exponential or catenoidal). Then, a simple metallic cylinder, the length ofwhich is an integer number of half wavelengths, transfers the acoustic? energy to the workpiece. Sometimes, coupling devices with special shapesare used, for example to modify the vibration direction , to sumup the acoustic power from several transducers or to transferthe acoustic power from one transducer to several tools . Thefixing of the transducer or any acoustic components to the machine body isensured by different types of bearings, which are placed in nodal zones, sothat no disturbance is created.

The design of such transducers has generally been carried out usingequivalent electrical circuitsand this method has allowed aclass1cal analysis of power problems . However, thisapproach does not take account of the distributed nature of inertia andstiffness and, in most cases, it provides accurate results only if it isused as an empirical method, the values of the lumped electrical componentsbeing deduced from measurements. To overcome this problem and to describecorrectly the acoustic wave propagation in these structures, the transfermatrix approach has been used for a long time and is generallysufficient for quantitative analyses and forecasts .Nevertheless it is restricted to plane wave propagation and must be given up when more complex s truc ture geometries or displacement fields areconcerned . This is the case for actually three di mensional s truc tures(special coupling devices... for structures wi th lateral dimensions equalto or larger than one quarter of a wavelength, for structures with rapidvariations of their crosS section, or when complex motions (flexural orradial motions) occur . Then, only the finite element method is able toprovide an efficient help to the designer.

sale the right products instead of the expensive one

Rps-sonic, consisted with a couple of young people who love ultrasonic very much.The founding members of RPS-SONIC have an average degree of Bachelor's degree or above. They have been in the ultrasonic industry for more than 5 years and have rich experience in ultrasound. The company's business philosophy is: Do not blindly promote any product, find the right product for the customer. So before each order, we will confirm all the details, including application details, equipment conditions, equipment specific information.

And we have the Professional import and export company， HangZhou LanBen Trade Co., Ltd, can export to any country wordwide.

Before year 2012, we only sale second branson / dukane / rinco / herrman/telsonic welding equipment , during these twenty year develop, we find, more and more people have problem with the core part of ultrasonic welding equipment -generator and transducer, so we decided to start our business of transducer and generator of our own transducer and generator. Many of the end user meet the transducer problem, they don’t know why transducer broken, and changing the expensive transducer one by one. Actually, one branson /dukane /rinco transducer can use 10~30 year, even the cheapest transducer can use about 5 years. So there must some reasons if your transducer broken in one year. That’s why we want build Rps-sonic, we need to help more end user to know more about transducer , to use ultrasonic equipment better, to save cost when meet problem.

The same to generator, Unreasonable operation may shorter the use-life of ultrasonic generator. So we have to make technical inquiry before operate ultrasonic welding machine. The key point of ultrasonic machine is resonance, only keep every part in resonance can make the system in best work environment.

Till now , we still have a lot of Branson /dukane/ rinco/ herrman telsonic welding machine, so that we can confirm every transducer/generator we made can matching to the original machine.

Of course we can make the transducer/generator replace for Branson /dukane/ rinco/ herrman telsonic welding machine, we can also make transducer/generator for any application of your ultrasonic equipment. We supply OEM service for oversea customers, we already have OEM customer in USA and German.

If you have any problem in ultrasonic area, welcome contact Rps-sonic.
