Solving the performance parameters of welding horn

Parameter:

ultrasonic weldind horn

The ultrasonic welding horn is the contact interface between the ultrasonic welding machine and the material. Its main function is to uniformly and effectively transmit the longitudinal mechanical vibration output from the horn to the material. The materials used are usually high-quality aluminum alloys or even titanium alloys. Because the design of plastic materials changes a lot, and the appearance varies widely, the horn also changes accordingly. The shape of the working surface must be well matched with the material, so that the plastic is not damaged during vibration; at the same time, the first-order longitudinal vibration must be coordinated with the output frequency of the welding machine, otherwise the vibration energy will be consumed internally. When the horn vibrates, stress concentration will occur locally. How to optimize these local structures is also a problem to be considered during design.
The forms were compiled and programmed using Microsoft Excel spread sheet software. The basic information that needs to be input when solving includes the working frequency, material, density, Young's modulus, wave velocity, Poisson's ratio, wide-end diameter and narrow-end diameter of the welding horn. Spreadsheets simultaneously solve and feedback exponential, catenary, conical and stepped welding horn with commonly used description parameters such as magnification factor, resonance length, displacement nodes, and locations of stress maxima. The difference between the calculation results of the four types of welding horns with the same initial conditions can be visually identified through the table. More ideal calculation results can be obtained by continuously adjusting the initial conditions (mainly by adjusting the external dimensions and examining the theoretical amplification factor of the horn).
Parameterized drawing of ultrsonic welding horn

In order to meet the needs of further drawing or designing of ultrasonic welding horn, Excel spreadsheets calculate the overall dimensions and key point coordinates of various welding horn, combined with the language rules of Au-toLISP and ANSYS APDL parametric secondary development design software, and automatically compile parameters Modeling program. Enter the modeling program into the command window of AutoCAD and ANSYS engineering design software to complete the plan drawing and 3D modeling of the welding horn, and provide horn drawing or finite element analysis.
The design uses hard aluminum as the horn material, and enters the wide-end diameter D1 and narrow-end diameter D2 for trial and error. Obviously, with the same cross-section dimensions at both ends, the stepped horn is easier to obtain high gain. Determine the horn magnification factor and resonance length for both end face diameters after leaving margin for end face avoidance

Comparison of finite element analysis

Using the ANSYS APDL parametric modeling program obtained in the example, the modal analysis is performed in the AN-SYS environment. The model was meshed with SOLID95 elements, and a total of 9,670 elements and 14,786 nodes were generated, which were solved using Lanczos algorithm. The first-order longitudinal vibration frequency of the horn is f = 20044Hz.

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.
