ULTRASONIC WELDING PRESS Russian patent published in 2005 - IPC

FIELD: equipment for welding components made out of thermoplastics.

SUBSTANCE: the invention is pertaining to the field of ultrasonic welding equipment, in particular to ultrasonic welding press used for welding components made out of thermoplastics and may to be used in different branches of industry, where connections of plastic components or assemblies to each other are used. The ultrasonic welding press contains a unit of ultrasonic converter with a waveguide, a support unit, a drive gear of welding pressure and a cradle. The supporting unit is mounted on the same shaft with the waveguide and has a capability to change space interval between them. The welding pressure drive contains a pneumatic power cylinder with a coupling rod mounted with a capability to transfer a pneumatic effort to the unit of the hypersonic converter. Two poles of the cradle are placed in parallel to the waveguide axis and in symmetry to its shaft. Three other bearing bars of the cradle are located in the plains perpendicular to the poles. At that the upper bearing bar is a support for the pneumatic power cylinder and the middle bearing bar is mounted with a capability of relocation on the poles. On its symmetry axis oppositely to the coupling rod of the pneumatic power cylinder there is a boss. The waveguide passes through an aperture located in middle of the middle bearing bar, which is rigidly connected with the unit of the ultrasonic converter in the plane of location of zero oscillations of the waveguide. The invention ensures decrease of losses of ultrasonic power.

EFFECT: the invention ensures decrease of losses of ultrasonic power.
