Torsional welder

Abstract

The invention provides a torsional welder, which comprises two transducers, an amplitude modulator, a fixing piece and a die head, wherein the amplitude modulator is provided with a section part; thefixing piece is fixedly arranged at one end of each transducer, and is fixedly arranged on the section part of the amplitude modulator in a penetrating way; the die head is arranged at the output endof the amplitude modulator; and the amplitude modulator has an included angle relative to the two transducers. Therefore, by means of high-frequency vibration (with micro displacement) which is generated by the two transducers and is converted from electric energy into mechanical energy, the amplitude modulator changes the amplitude and transmits the vibration to the die head, and the two transducers drive the amplitude modulator to perform high-speed and high-frequency forward and reverse rotation by using two reciprocating vibration thrusts and transmit the forward and reverse rotation to the die head to ensure that the amplitude modulator performs high-frequency and high-speed forward and reverse rotation, so that when the torsional welder is used for processing a workpiece to be processed, the workpiece can be stably welded during welding processing because the forward and reverse rotation (displacement) amplitude of the die head during high-frequency and high-speed forward and reverse rotation processing is quite small.

Description

technical field [0001] The invention relates to a welder, especially a torsion welder. Background technique [0002] The common ultrasonic spot welding machine is a common welding equipment. Its main components include an ultrasonic generator and a transducer, a booster, and a horn (or welding head, The energy conversion welding head mechanism composed of three components such as mold) can be driven by a power mechanism such as a pneumatic cylinder, and move up and down within a certain stroke range to pressurize and weld the workpiece. The working principle of the ultrasonic spot welding machine is that the ultrasonic generator generates high-frequency electric energy of about 15KHz to 40KHz, and then the electric energy is converted into mechanical motion (vibration) of the same frequency by the transducer, and then the amplitude modulator converts the mechanical After the movement changes the amplitude, it is transmitted to the die head. When the die head touches the wor...

Problems solved by technology

[0003] Therefore, in this technical solution, the "spot welding machine structure" and "spot welding machine structure" such as China Taiwan Patent Announcement No. M554387 and M554388 are disclosed, wherein the processing of the workpiece is carried out by driving the welding head up and down Processing and welding, however, due to the vertical and longitudinal lifting processing mode (with gravitational potential energy), the lifting displacement force is relatively large, and the workpiece (such as two pieces of plastic) is easy to process when welding the workpiece. When dust is generated, the generation of dust (if powder remains) will pollute the contents of the bag for finished products such as plastic bags, such as blood storage bags , although the finished product of the bag body with residual powder can be cleaned through the cleaning process, but it also requires an additional processing step, resulting in a more cumbersome process and high manufacturing costs. end) The dust produced during welding is a problem that must be solved for the wire system that does not allow water cleaning
