本発明は、超音波加工に用いられる横長板状の
工具ホーンに係り、特に板厚方向側面を加工面と
して使用する超音波加工用工具ホーンに関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a tool horn in the shape of an oblong plate used for ultrasonic machining, and particularly to a tool horn for ultrasonic machining that uses the side surface in the thickness direction as a machining surface. Regarding.
［従来の技術］

被溶着材に接触させ、被溶着材に振動エネルギを
供給して溶着を行なう構造になつている。[Prior Art] Generally, a tool horn used for ultrasonic plastic welding has a structure in which the radiation surface opposite to the input surface is brought into contact with the material to be welded, and vibration energy is supplied to the material to be welded to perform welding. ing.

射面の変位が均一にならないという問題がある。 By the way, in this type of tool horn, it is important that the radiation surface vibrates longitudinally with almost uniform vibration changes in the same phase, but if the width of the horn exceeds 1/4 wavelength of the used vibration frequency. However, there is a problem in that the displacement of the radiation surface is not uniform.

ている。 Therefore, conventionally, as shown in Japanese Patent Application Laid-open No. 60-68926, multiple slots were formed in the plate surface between the input surface and the emission surface at intervals of 1/4 wavelength or less in the width direction. The aim is to equalize the displacement of the radiation surface.

期待できないという問題がある。[Problems to be Solved by the Invention] The conventional ultrasonic machining tool horn has no particular problem when used as a welding tool by bringing the radiation surface into contact with a material to be welded. Alternatively, if one side is used for transporting objects or for heating up heat due to the stress effect on the radiation surface, there is a problem that a sufficient effect cannot be expected due to the presence of the slot.

面においては、応力効果による温度上昇に伴なう
流動性の改善が実現できるものと予想される。 That is, in the ultrasonic machining tool horn, the vertical displacement is in opposite directions on the input surface side and the radiation surface side, with the center position in the vertical width direction (1/4 wavelength position) as a border. Therefore, by taking advantage of this property and using only the 1/4 wavelength plane on the radiation surface side to transport the object, a sufficient transport effect can be obtained, and furthermore, the radiation surface at the tip can reduce the stress effect. It is expected that the fluidity will be improved as the temperature increases.

ため、充分な搬送効果等が得られないという問題
がある。 However, in conventional ultrasonic machining tool horns, as mentioned above, multiple slots are provided on the plate surface between the input surface and the radiation surface, and these slots are not used to apply vibrations. Not only is this impossible, but the fluid also accumulates in that area, making it impossible to obtain a sufficient conveying effect.

In the horizontally long plate-shaped ultrasonic machining tool horn, a groove cut from the input surface toward the radiation surface is formed in the region on the input surface side excluding the region of 1/4 wavelength from the radiation surface in the width direction. It is characterized in that a plurality of lines are provided at intervals of four wavelengths or less.

効果が得られる。[Function] In the ultrasonic machining tool horn according to the present invention, no slot is provided in the 1/4 wavelength region on the radiation surface side. Therefore, even if objects are conveyed using both sides in the plate thickness direction, one side, or even the radial surface of this area, the conveyance of the object is not obstructed by the slot, and a sufficient conveyance effect can be achieved. is obtained.

が期待できなくなる。 By the way, in the case of a horn whose width dimension exceeds 1/4 wavelength with respect to the vibration frequency used, it is impossible to achieve in-phase and uniform displacement on the radiation surface as described above unless a slot is provided. If the displacement of the radiation surface is non-uniform, the displacement on both sides in the thickness direction will also be non-uniform in the width direction of the board, reducing the uniform object conveyance effect and preventing the expected effect. become unable.

能となる。 However, in the present invention, 1/4 from the radiation surface
In the region on the input surface side excluding the wavelength region, cut a groove from the input surface to the radiation surface by 1/4 in the width direction.
Since a plurality of them are provided at intervals of less than the wavelength, it is possible to equalize the displacement of the radiation surface without providing a slot in the 1/4 wavelength region on the radiation surface side.

なつている。 1 to 3 show an example of a tool horn for ultrasonic machining according to the present invention. This tool horn 1 is made of a metal such as titanium alloy, duralumin, monel, or phosphor bronze. It is formed into a plate shape, and the vertical width L between the input surface 2, on which the ultrasonic vibration F is applied at one point in the center, and the radiation surface 3 opposing this is approximately half the frequency λ of the ultrasonic vibration F. It is set to approximately λ/2 of the length, and is designed to resonate at a half wavelength.

５／２４λが最もよい。 Further, the width W of the tool horn 1 is set to approximately 3/4λ with respect to the frequency λ of the ultrasonic vibration F, as shown in FIG.
Two grooves 5 having a width W 1 of λ/24 or less are provided at positions where the groove is divided into thirds in the width direction. and,
Each width dimension W 2 between adjacent grooves 5 and between the groove 5 and the end face in the width direction of the tool horn 1 is set to be λ/4 or less. This width dimension W 2 changes depending on the width W of the tool horn 1, but ideally it is best set to 5/24λ.

A cut is made in the side area from the input surface 2 toward the radiation surface 3, and the dimension L1 between the end of each groove 5 and the radiation surface 3 is half the vertical width L of the tool horn 1. The length is set to be L/2.

It is formed to have a slightly shorter dimension than the center portion 1a between adjacent grooves 5, and the end surface on the input surface 2 side is cut into a chevron shape. As a result, the displacement of the radiation surface 3 can be made more uniform than in the case where the grooves 5 are simply provided.
次に、本実施例の作用について説明する。 Next, the operation of this embodiment will be explained.

缶、箱等に所定量ずつ詰め込まれる。 When conveying an object using the tool horn 1, as shown in FIGS. A tool horn 1 is installed, and an ultrasonic vibration F having a resonant frequency of the tool horn 1 is applied to one point in the center of the input surface 2. Then, the tool horn 1 is displaced in the vertical direction with the input surface 2 side and the radiation surface 3 side being in opposite phases with the center position in the vertical width direction as a boundary.
Therefore, if an object 7 such as a liquid object with poor fluidity, a highly viscous object, or a granular object is thrown into the shooter 6, the longitudinal displacement of both sides 4, 4 of the tool horn 1 will cause the The object 7 is conveyed towards the radiation surface 3. The object 7 conveyed to the radiation surface 3 is heated due to the stress effect caused by the displacement of the radiation surface 3, and its fluidity is improved. This object 7 is conveyed in the longitudinal direction along the bottom of the shooter 6, and is led to the next process or packed in a predetermined amount into cans, boxes, etc. as a product.

物体７を良好に搬送することができるとともに、
流動性を改善することができる。 By the way, when ultrasonic vibration F is applied to one point in the center of the input surface 2 of the tool horn 1, the center part 1 shown in FIG.
Most of the displacement a is in the vertical direction, but the end portions 1b on both sides are also displaced in the vertical direction, but they also cause bending vibrations that vibrate in the left-right direction in FIG. By processing the end portion 1b into a chevron shape that is slightly shorter than the central portion 1a, both side surfaces 4, 4 and the radiation surface 3 vibrate uniformly and in phase, and their displacements are made uniform. Therefore, λ/4 on the radiation surface 3 side
Coupled with the fact that there are no slots in the area of
The object 7 can be transported well, and
Fluidity can be improved.
第５図および第６図は、本発明の第２実施例を

領域の構造を変更したものである。 5 and 6 show a second embodiment of the present invention, in which the structure of the λ/4 region on the input surface 2 side of the tool horn 1 is changed.

is larger than the width W 4 of the ends 1b on both sides,
Moreover, the dimension L1 between the end of each groove 5 and the radiation surface 3 is set to be less than λ/4, and the dimension L1 between the end of each groove 5 and the radiation surface 3 is smaller than the length L/2, which is half the vertical width L of the tool horn 1. The dimensions are also set to be slightly longer. Further, each end portion 1b
is formed to be considerably shorter than the central portion 1a,
The end face on the input surface 2 side has a shape in which the outer end in the width direction is cut obliquely.
なお、その他の点については、前記第１実施例
と同一構成になつており、作用も同一である。 In other respects, the structure is the same as that of the first embodiment, and the operation is also the same.

By simply providing a groove that cuts from the input surface toward the emission surface in the area on the input surface side excluding the wavelength region, it is possible to equalize the displacement on the emission surface side. When conveying an object using both sides or one side in the thickness direction of the area, a sufficient conveying effect can be obtained, and at the radial surface of the tip, the fluidity of the object is improved due to the temperature increase caused by the stress effect. It is particularly effective for use in transporting objects with poor fluidity.

However, in the case of the present invention, the displacement on the radiation surface side can be easily made uniform by simply adjusting the shape of the end on the input surface side. It is particularly effective for ultrasonic plastic welding.
