Abstract
The utility model discloses a torsion type energy converting system. The system comprises a transducer; an amplitude changing rod is mounted on the output end of the transducer; a rod-shaped sound pole is mounted on the front end of the amplitude changing rod; the system also comprises a plurality of through grooves; an included angle is formed between the through grooves and a horizontal installing surface; and the through grooves are uniformly arranged on the circumference of a rod body of the sound pole in a row, or are uniformly arranged on the circumference of a rod body of the amplitude changing rod in a row. Via the through grooves, after the system is mounted on an ultrasonic welding machine, when the transducer is working, ultrasonic waves generated by the transducer are non-continuously transmitted in the shape of a vortex along the amplitude changing rod to a working end of the sound pole, and contact faces of two to-be-welded objects vibrate much violently, so the objects can be closely and tightly combined together, and welding firmness between the objects is improved. The system is suitable for ultrasonic welding.
Description
Technical field
The utility model relates to a kind of welding equipment in ultrasonic bonding field, especially relates to a kind of torsional mode energy converting system.
Background technology
Ultrasonic bonding is to utilize ultrasonic dither ripple along rigid metal material part, to be delivered to the tight object according to pasting of two need welding, the in the situation that of pressurization, making the function ultrasonic wave on two object to be welded top layers vibrate and make the mutual friction of two articles phase cause between molecular layer along a fixed-direction sees through and joins mutually, two articles top layer molecular grating enters the other side's recombination and integration each other, thereby can be combined as a whole tightly closely.Ultrasonic wave metal welding advantage: 1), not melting of welding material thereby be not oxidized, not crisp and maintain the former mechanical force of metal and conductive characteristic; 2), can maintain the conductance of virgin metal after welding, thereby conduct electricity very well, resistance coefficient is extremely humble, and resistance weakens ignores; 3) even if, there is electrodeposited coating on weld metal surface and also all can carries out effective welding; 4), weld interval is short, do not need the auxiliary heatings such as any scaling powder, gas or scolder; 5), welding no-spark or arc phenomenon, Environmental Safety and power consumption are few.
Existing energy converting system is generally on the output of transducer and is connected with ultrasonic transformer, is connected with applicator on ultrasonic transformer, and ultrasonic wave transducer being produced by ultrasonic transformer is passed to applicator regularly along a fixed-direction, by vibration, two objects is pressed together.
For ultrasonic wave, realizing torsional mode transmission does not also have relevant research, now needs a kind of energy converting system that can realize the transmission of ultrasonic torsional formula.
Utility model content
The purpose of this utility model, is to provide a kind of torsional mode energy converting system.
The solution that the utility model solves its technical problem is: a kind of torsional mode energy converting system, it comprises transducer, on the output of described transducer, ultrasonic transformer is installed, the front end of described ultrasonic transformer is provided with shaft-like applicator, also comprise several grooves, described groove becomes angle with horizontal mounting surface, and groove is equably on the circumference of the shaft that is arranged on applicator in a row or groove equably on the circumference of the shaft that is arranged on ultrasonic transformer in a row.
As the further improvement of technique scheme, the angle between described groove and horizontal mounting surface is 30 ° ~ 60 °.
As the further improvement of technique scheme, the width of described groove is n λ/2, and n is positive odd number, and λ is hyperacoustic wavelength that transducer produces.
As the further improvement of technique scheme, the quantity of described groove is 3.
As the further improvement of technique scheme, the shaft that is provided with the applicator of groove is also provided with protective cover outward.
As the further improvement of technique scheme, the shaft that is provided with the ultrasonic transformer of groove is also provided with protective cover outward.
As the further improvement of technique scheme, between described applicator and ultrasonic transformer, be also furnished with ultrasonic transformer stationary magazine creel.
The beneficial effects of the utility model are: the utility model becomes the groove of angle by a row is set on applicator or ultrasonic transformer with horizontal mounting surface, after so the utility model being installed on ultrasonic welding machine, during work, the ultrasonic wave that transducer produces is passed on applicator along ultrasonic transformer, because the partition of groove the whirlpool that produces ripple make use, making hyperacoustic transmission is not to shake to propelling along traditional coherent straight line conduction, but generation noncontinuity, but be intensive torsional wave continuous shaking of following extremely, it becomes vortex shape to be passed to the working end of applicator, the contact-making surface vibration that makes to be welded between two articles is more violent, and phase mutual friction causes seeing through and joining mutually between molecular layer, two articles top layer molecular grating enters the other side's recombination and integration, thereby can be combined as a whole tightly closely, improve firm welding between the two.
The utility model is applicable to ultrasonic bonding.
Accompanying drawing explanation
