Description
Technical field
The utility model designs a kind of supersonic mould, more particularly to a kind of 20KHz prevents the supersonic mould of cry.
Background technology
In different application scenarios, due to welding object difference, it is necessary to use corresponding weld mold.For larger portion
Part ensures product quality, it is a long and narrow bar shaped to need large-sized supersonic mould, radiating surface to improve productivity
Face or the one long and comparable large scale rectangular surfaces of width.In actual operation, it is desirable that the resonant frequency of tool must wait
In excitation energy converter and the resonant frequency of wire bonding, transducer efficiency decline otherwise will be generated, the vibration mode of tool is sent out
Many problems such as changing.For that purpose it is necessary to theoretically accurately determine the resonant frequency of tool.Lateral dimension is much smaller than
The vibratory tool of longitudinal size (such as lateral dimension is more than 1/4 longitudinal wave wavelength), influence of the oscillation crosswise to extensional vibration is little,
It can be ignored.The result met can be obtained and tested at this time with one-dimensional Theory of Vibration.But large scale is vibrated
System, since the lateral dimension of tool is close or larger than the longitudinal wave wavelength corresponding to vibrational system working frequency, tool produces
Serious oscillation crosswise.Also, oscillation crosswise influences each other with extensional vibration, at this point, one-dimensional Theory of Vibration will generate it is larger
Error, it is necessary to develop new theory and needs are designed with the clear such large scale system of foot, effectively inhibit the transverse direction of supersonic mould
Vibration and the uniformity coefficient for improving mold swept area Displacements Distribution.
Spread speed of the ultrasonic wave of 20KHz in aluminium is about 5000m/s in the prior art, is easy when ultrasonic wave heats
Lateral displacement is generated, influences to heat effect, and easy to produce cry.
Therefore, there is an urgent need for the supersonic moulds that a kind of 20KHz prevents cry.
Utility model content
In view of this, the utility model proposes the supersonic moulds that a kind of 20KHz prevents cry.
The technical solution adopted in the utility model is：
A kind of 20KHz prevents the supersonic mould of cry, including：Main body：Main body is cuboid aluminium block, and main body is transversely square
To length be 130mm, main body offers the slotted hole of trepanning in transverse direction, the center of slotted hole and the center weight of main body
It closes, the trepanning of slotted hole, main body is equipped with elongated slot along the longitudinal direction, and elongated slot intersects with slotted hole；The vibration ultrasonic wavelength of main body
For 250mm, the width of slotted hole in transverse direction is 10mm~25mm, and the plummet distance to bottom part body at elongated slot both ends is not
It is equal.
It is the 1/25~1/10 of ultrasonic wavelength by opening up length, can preferably inhibits oscillation crosswise, avoid ultrasonic wave
During hot melt, supersonic mould generates lateral displacement, influences to heat effect.
Preferably, elongated slot inner wall is arc.
Elongated slot inner wall is arc, can gradually amplify amplitude.
Preferably, the width of slotted hole along the longitudinal direction is 14.5mm.
The width of slotted hole is 14.5mm, best to the lateral displacement eradicating efficacy of the generation of shear wave.
Preferably, the length of slotted hole in transverse direction is 65cm.
When oval hole length too in short-term, since the oscillation crosswise of supersonic mould is distributed across on the entire side of mold,
It is thus impossible to effectively eliminate oscillation crosswise, while the Displacements Distribution of mold vibration radiating surface can not be effectively improved.But
It is, it is too close due to opening mutually high mold radiating surface when oval hole length is too long, make occur displacement point in the acoustic irradiation face of tool
Cloth non-uniform phenomenon influences mold radiation efficiency and product quality, can effectively eliminate cry.
Preferably, the wherein side of elongated slot in transverse direction to the both sides of main body in transverse direction be 65mm.
The beneficial effects of the utility model：
1, it is the 1/25~1/10 of ultrasonic wavelength by opening up length, can preferably inhibits oscillation crosswise, avoid ultrasound
During wave heats, supersonic mould generates lateral displacement, influences to heat effect.
2, elongated slot inner wall is arc, can gradually amplify amplitude.
3, when oval hole length too in short-term, since the oscillation crosswise of supersonic mould is distributed across on the entire side of mold
, it is thus impossible to effectively eliminate oscillation crosswise, while the Displacements Distribution of mold vibration radiating surface can not be effectively improved.
It is too close due to opening mutually high mold radiating surface but when oval hole length is too long, make occur position in the acoustic irradiation face of tool
Shifting is unevenly distributed phenomenon, influences mold radiation efficiency and product quality.The width of slotted hole is 14.5mm, and slotted hole is transversely
The length in direction is that 65cm is best to the eradicating efficacy of shear wave, prevents from calling.
