Description

Technical Field

[0001] This invention relates to the field of cutting tool technology, and more specifically, to a high-frequency ultrasonic cutting tool that is easy to puncture and cut. Background Technology

[0002] In the textile and footwear processing industries, it is usually necessary to process the finished fabrics in various ways, and cutting equipment is needed to cut the fabrics into the required specifications.

[0003] Traditional cutting equipment (publication number: CN116926940A) uses an external drive device to make the cutting head perform high-frequency point punching, and the point punches are connected to form a line for cutting. This method is very easy to generate burrs during cutting and cannot seal the edges, so further processing is required after cutting, which increases production costs. Alternatively, cutting equipment (publication number: CN115070072A) can be used to reduce and avoid material breakage and burrs at the cut. However, the angle between the blade and the material being cut is difficult to adjust precisely during cutting, resulting in a low yield rate. After long-term cutting, the blade is prone to deviate and is not easy to adjust flexibly, which reduces production efficiency.

[0004] Publication No.: CN116926940A, a cutting mold for cutting flexible materials is disclosed, including a worktable and a fixed frame installed on the top of the worktable, and further including: a cylinder, disposed on the top of the fixed frame, the output end of the cylinder passing through the fixed frame and fixedly connected to a fixed plate; a cutting assembly, disposed directly below the fixed plate, for cutting the flexible material; the present invention enables the fixing of the flexible material while performing ironing, preventing wrinkles in some parts of the flexible material from affecting the subsequent cutting dimensions, further improving the cutting efficiency and quality, and enabling the change of the wrinkle direction of the flexible material, further improving the efficiency of wrinkle removal, and enabling timely treatment of moisture adhering to the surface of the flexible material, further reducing unnecessary workload in the later stages.

[0005] Publication No. CN115070072A discloses an ultrasonic vibration cutting tool for surface processing. An ultrasonic generator and an ultrasonic transducer are electrically connected. The ultrasonic transducer converts the electrical energy of the ultrasonic generator into axial mechanical vibration of the same frequency. An amplitude modulator adjusts the vibration amplitude and transmits the vibration energy to the cutting head, causing the cutting edge to generate a cutting motion of the same frequency. The direction of the cutting edge movement is tangential to the cutting tip. The cutting head extends outside the housing and can be used to cut burrs. An elastic clamping mechanism provides lateral elasticity to the housing, causing the cutting head to tilt and press against the workpiece surface. For uneven workpiece surfaces, the cutting head is dragged away from the cutting edge during feeding. During this process, the cutting edge does not directly face the workpiece surface, avoiding cutting damage. This tool has low requirements for the surface shape of the part. The elastic clamping mechanism presses the cutting head against the workpiece surface, maintaining constant contact with the workpiece surface, exhibiting strong adaptability and the ability to remove burrs and flash according to the shape.

[0006] How to further improve the cutting tools to make them more efficient and precise in adjusting the angle and improving the cutting yield has become a problem that needs to be solved. Summary of the Invention

[0007] To address the challenge of efficiently and precisely adjusting the angle of ultrasonic cutting tools to improve cutting yield, this invention proposes a high-frequency ultrasonic cutting tool that facilitates piercing and cutting. The tool comprises a first housing 1, a second housing 2, an electric slip ring 3, an ultrasonic transducer assembly 4, a cutting head 5, and an auxiliary positioning mechanism 6.

It also assists in connecting the positioning mechanism 6 to the external cutting machine mounting port, improving adjustment and installation efficiency. A limiting chamber 45 and parallel edges 46 are provided for mounting the ultrasonic transducer assembly 4, ensuring stable assembly and reducing the failure rate. The flat sword-shaped cutting head facilitates cutting, and a drag-reducing surface 534 reduces resistance, significantly lowering the risk of tool breakage. A pre-compression assembly 9 pre-compresses the material to facilitate cutting by the cutting head 5, improving the cutting yield. A flexible ring 8 is provided to assist in stress relief and prevent damage to the first and second housings when the first and second housings 2 are compressed.

The end of the ultrasonic transducer assembly 4 away from the first housing 1 is connected to the handle 51. The handle 51, neck 52, and working part 53 are interconnected. The handle 51, neck 52, and working part 53 are integrally formed or the handle 51, neck 52, and working part 53 are separate structures. It is more preferred that the handle 51, neck 52, and working part 53 are integrally formed structures.

[0013] Furthermore, when the handle 51, neck 52 and working part 53 are separate structures, the handle 51 and neck 52 are integrally formed and connected, and the working part 53 is provided on the side of the neck 52 away from the end of the handle 51. The working part 53 and the neck 52 are detachably connected by screws.

[0014] Furthermore, two working parts 53 are provided below the neck 52. The working parts 53 are flat sword-shaped. Adjacent working parts 53 are horizontally symmetrically arranged and form cutting blades. Each working part 53 includes a first cutting surface 531, a second cutting surface 532, a third cutting surface 533, and a drag-reducing surface 534. The first cutting surface 531 and the second cutting surface 532 are symmetrically arranged. Adjacent first cutting surfaces 531 form first cutting blades 535, and adjacent second cutting surfaces 532 form second cutting blades 536. A drag-reducing surface 534 is provided between the first cutting surface 531 and the second cutting surface 532. A third cutting surface 533 is provided below both the first cutting surface 531 and the second cutting surface 532. Adjacent third cutting surfaces 533 are symmetrically arranged. Adjacent third cutting surfaces 533 form third cutting blades near the first cutting blades 535 and the second cutting blades 536.

[0015] Furthermore, the blades formed by the first cutting edge 535 and the second cutting edge 536 are acute angles.

[0016] Furthermore, during cutting, one of the following can be selected: the first cutting blade 535 for single-blade cutting, the second cutting blade 536 for single-blade cutting, or the first cutting blade 535 and the second cutting blade 536 for double-blade cutting. It is more preferred to use the first cutting blade 535 and the second cutting blade 536 for double-blade cutting.

[0017] Furthermore, the angles formed by the first cutting surface 531, the second cutting surface 532, and the drag-reducing surface 534 are obtuse angles, and the angles formed by the third cutting surface 533 and the drag-reducing surface 534 are also obtuse angles.

[0018] Furthermore, the downward angle formed by the drag-reducing surface 534 with the first cutting surface 531 and the second cutting surface 532 is 25°-30°, preferably 28°, to reduce the resistance encountered during cutting.

[0019] In some embodiments, the hollow structure in the middle of the slip ring 3 is connected to a gas supply mechanism, which is used to supply air downwards to dissipate heat from the ultrasonic transducer assembly 4 and the blade head 5.

[0020] In some embodiments, the ultrasonic transducer assembly 4 includes an ultrasonic transducer body 41 and a connecting flange 42. The ultrasonic transducer body 41 has a connecting flange 42 on its side. The inner wall of the first housing 1 away from the slip ring 3 has a limiting block 43. The first housing 1 away from the cutter head 5 has a step 44. The bottom surface of the limiting block 43 corresponds to the top surface of the step 44 and forms a limiting chamber 45 between them. The connecting flange 42 abuts against the limiting chamber 45. The ultrasonic transducer body 41 remains relatively stationary with the first housing 1 and the second housing 2 through the connecting flange 42.

[0021] Furthermore, the connecting flange edge 42 is provided with a plurality of first ventilation holes 421 at intervals, which are used to dissipate the heat generated by the ultrasonic transducer assembly 4 and the cutting head 5 from the inside to the outside during processing.

[0022] Furthermore, the limiting block 43 is arc-shaped or semi-arc-shaped, with a semi-arc shape being more preferred. When the limiting block 43 is arc-shaped, an arc-shaped limiting block 43 is provided on the inner wall of the first housing 1 away from the electric slip ring 3. When the limiting block 43 is semi-arc-shaped, multiple limiting blocks 43 are evenly spaced on the side of the inner wall of the first housing 1 away from the electric slip ring 3. More preferably, two semi-arc-shaped limiting blocks 43 are provided, with two adjacent semi-arc-shaped limiting blocks 43 arranged symmetrically.

[0023] Furthermore, the side of the connecting flange 42 away from the semi-circular limiting block 43 is also a parallel side 46, the cross-section of which is rectangular, and the parallel side 46 is used to restrict the horizontal rotation of the ultrasonic transducer body 41.

[0024] Furthermore, the second housing 2 has multiple second ventilation holes 21 spaced apart near the cutter head 5 on its side wall, which are used to dissipate heat generated by the ultrasonic transducer assembly 4 and the cutter head 5 from the inside to the outside during processing.

[0025] In some embodiments, a flexible ring 8 is provided between the first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are subjected to pressure, the flexible ring 8 is used to assist in unloading the force, prevent damage to the first housing 1 and the second housing 2, and prevent overload during installation when the threaded connection is connected.

[0026] In some embodiments, the end of the second housing 2 away from the ultrasonic transducer assembly 4 is also connected to a pre-compression assembly 9. The pre-compression assembly 9 is used to protect the cutting head 5 and to pre-press the material to be cut during cutting, so that the cutting head 5 can cut. The pre-compression assembly 9 includes a pressure plate 91 and an elastic assembly 92. The outer wall of the end of the second housing 2 away from the ultrasonic transducer assembly 4 is sleeved with or integrally formed with the inner wall of the pressure plate 91. An elastic assembly 92 is provided between the second housing 2 and the pressure plate 91, preferably a spring. When the ultrasonic transducer assembly 4 drives the cutting head 5 to move downward, the pressure plate 91 drives the spring to move upward to press against the material to be cut, and the cutting head 5 cuts. After cutting is completed, the pressure plate 91 returns to its original position as the spring moves downward.

[0027] Furthermore, the outer wall of the second housing 2 away from the ultrasonic transducer assembly 4 is also provided with a second guide groove 22. The pressure plate 91 is connected to the second guide groove 22 through the sliding column 23. When the ultrasonic transducer assembly 4 drives the cutter head 5 to move downward, the pressure plate 91 moves upward along the direction of the second guide groove 22 with the sliding column 23 to press against the material to be cut. The cutter head 5 performs cutting. After the cutting is completed, the pressure plate 91 moves downward along the second guide groove 22 with the sliding column 23 to reset.

[0028] Furthermore, the top diameter of the pressure plate 91 is smaller than the bottom diameter, which increases the contact area between the pressure plate 91 and the fabric to be cut, making cutting easier.

[0029] In some embodiments, the first housing 1 is threadedly connected to the second housing 2, and the ultrasonic transducer assembly 4 is threadedly connected to the cutter head 5.

[0030] The beneficial effects of this invention are as follows: This invention proposes a high-frequency ultrasonic cutting tool that is easy to pierce and cut, including a first housing 1, a second housing 2, an electric slip ring 3, an ultrasonic transducer assembly 4, a cutting head 5, and an auxiliary positioning mechanism 6. The auxiliary positioning mechanism 6 is detachably connected to the outer wall of the first housing 1 to assist the cutting head 5 in adjusting the cutting edge. It also assists the positioning mechanism 6 in correspondingly connecting with the external cutting machine mounting port, improving adjustment and installation efficiency. The ultrasonic transducer assembly 4 is installed in a limiting chamber 45 and a parallel edge 46, which makes its assembly stable and reduces the failure rate. The flat sword-shaped cutting head is easy to cut, and the drag-reducing surface 534 reduces resistance, greatly reducing the risk of blade breakage. The pre-compression assembly 9 is set to pre-compress the cutting material to facilitate cutting by the cutting head 5, improving the cutting yield. The flexible ring 8 is set to assist in unloading force and prevent damage to the first housing 1 and the second housing 2 when the first housing 1 and the second housing 2 are squeezed. At the same time, it prevents overload during installation when the threaded connection is made, allows for position adjustment, and improves service life. Attached Figure Description

The tool is characterized in that: an electric slip ring 3 is provided at one end of the first housing 1, the middle of which is hollow; a second housing 2 is provided at the other end of the first housing 1; an ultrasonic transducer assembly 4 is provided within the cavity formed by the first housing 1 and the second housing 2; a power line passes through the hollow structure of the electric slip ring 3 and is electrically connected to the ultrasonic transducer assembly 4; a cutting head 5 is connected to the end of the ultrasonic transducer assembly 4 away from the electric slip ring 3; and an auxiliary positioning mechanism 6 is detachably connected to the outer wall of the first housing 1 to assist the cutting head 5 in adjusting its cutting edge. The auxiliary positioning mechanism 6 is also connected to the mounting port of an external cutting machine.

[0069] The first housing 1 has at least one adjustment groove 7 on the side wall away from the second housing 2. Each adjustment groove 7 is provided with an auxiliary positioning mechanism 6. The auxiliary positioning mechanism 6 includes a fixing component 61 and a positioning block 62. Each adjustment groove 7 is provided with a positioning block 62. The fixing component 61 is provided above the side of the positioning block 62. The positioning block 62 is connected to the first housing 1 through the fixing component 61.

[0070] The fixing component 61 includes a fixing strip 63 and screws. The inner side of the fixing strip 63 is provided with a first guide groove 64. The rear part of the positioning block 62 is connected to the adjustment groove 7, and the front part of the positioning block 62 is connected to the first guide groove 64. The positioning block 62 can be adjusted along the adjustment groove 7 and the first guide groove 64. A positioning point is provided at the center line of the front part of the positioning block 62. When the cutter head 5 is parallel or perpendicular to the positioning point, the cutter head 5 is installed correctly.

[0071] The positioning block 62 includes a protruding snap-fit ​​part 621 and a sliding abutment part 622. The rear part of the sliding abutment part 622 is correspondingly connected to the first guide groove 64. The front part of the sliding abutment part 622 is provided with a protruding snap-fit ​​part 621, and the upper end of the front part of the protruding snap-fit ​​part 621 is correspondingly connected to the first guide groove 64.

[0072] The cutter head 5 includes a handle 51, a neck 52, and a working part 53. The end of the ultrasonic transducer assembly 4 away from the first housing 1 is connected to the handle 51. The handle 51, neck 52, and working part 53 are connected to each other. The handle 51, neck 52, and working part 53 are integrally formed structures.

[0073] Two working parts 53 are provided below the neck 52. The working parts 53 are flat sword-shaped. Adjacent working parts 53 are horizontally symmetrically arranged and form cutting blades. Each working part 53 includes a first cutting surface 531, a second cutting surface 532, a third cutting surface 533, and a drag-reducing surface 534. The first cutting surface 531 and the second cutting surface 532 are symmetrically arranged. Adjacent first cutting surfaces 531 form first cutting blades 535, and adjacent second cutting surfaces 532 form second cutting blades 536. A drag-reducing surface 534 is provided between the first cutting surface 531 and the second cutting surface 532. A third cutting surface 533 is provided below both the first cutting surface 531 and the second cutting surface 532. Adjacent third cutting surfaces 533 are symmetrically arranged. Adjacent third cutting surfaces 533 form third cutting blades near the first cutting blades 535 and the second cutting blades 536.

[0074] The blades formed by the first cutting edge 535 and the second cutting edge 536 are acute angles.

[0075] When cutting, select the first cutting blade 535 to perform double-blade cutting with the first cutting blade 535 and the second cutting blade 536.

[0076] The angle formed by the first cutting surface 531, the second cutting surface 532 and the drag-reducing surface 534 is an obtuse angle, and the angle formed by the third cutting surface 533 and the drag-reducing surface 534 is an obtuse angle.

[0077] The downward angle formed by the drag-reducing surface 534, the first cutting surface 531, and the second cutting surface 532 is 28°, which is used to reduce the resistance encountered during cutting.

[0078] The hollow structure in the middle of the slip ring 3 is connected to a gas supply mechanism, which is used to supply air downwards to dissipate heat from the ultrasonic transducer assembly 4 and the cutter head 5.

[0079] The ultrasonic transducer assembly 4 includes an ultrasonic transducer body 41 and a connecting flange 42. The ultrasonic transducer body 41 has a connecting flange 42 on its side. The inner wall of the first housing 1 away from the slip ring 3 has a limiting block 43. The first housing 1 away from the cutter head 5 has a step 44. The bottom surface of the limiting block 43 corresponds to the top surface of the step 44 and forms a limiting chamber 45 between them. The connecting flange 42 abuts against the limiting chamber 45. The ultrasonic transducer body 41 maintains a relatively stationary state with the first housing 1 and the second housing 2 through the connecting flange 42.

[0080] The limiting block 43 is arc-shaped or semi-arc-shaped, with a semi-arc shape being more preferred. When the limiting block 43 is arc-shaped, an arc-shaped limiting block 43 is provided on the inner wall of the first housing 1 away from the electric slip ring 3. When the limiting block 43 is semi-arc-shaped, multiple limiting blocks 43 are evenly spaced on the side of the inner wall of the first housing 1 away from the electric slip ring 3. It is more preferred to provide two semi-arc-shaped limiting blocks 43, with two adjacent semi-arc-shaped limiting blocks 43 arranged symmetrically.

[0081] The connecting flange edge 42 is provided with a plurality of first ventilation holes 421 at intervals, which are used to dissipate the heat generated by the ultrasonic transducer assembly 4 and the cutting head 5 from the inside to the outside during processing.

[0082] The side of the connecting flange 42 away from the semi-circular limiting block 43 is also a parallel side 46. The cross-section of the parallel side 46 is rectangular, and the parallel side 46 is used to limit the horizontal rotation of the ultrasonic transducer body 41.

[0083] The second housing 2 has multiple second ventilation holes 21 spaced apart on its side wall near the cutter head 5, which are used to dissipate heat generated by the ultrasonic transducer assembly 4 and the cutter head 5 from the inside to the outside during processing.

[0084] A flexible ring 8 is also provided between the first housing 1 and the second housing 2. When the first housing 1 and the second housing 2 are subjected to pressure, the flexible ring 8 is used to assist in unloading the force, prevent damage to the first housing 1 and the second housing 2, and prevent overload during installation when the threaded connection is made.

[0085] The second housing 2, away from the ultrasonic transducer assembly 4, is also connected to a pre-pressing assembly 9. The pre-pressing assembly is used to protect the cutting head 5 and to pre-press the material to be cut during cutting, so that the cutting head 5 can cut. The pre-pressing assembly 9 includes a pressure plate 91 and an elastic assembly 92. The outer wall of the second housing 2 away from the ultrasonic transducer assembly 4 is sleeved with or integrally formed with the inner wall of the pressure plate 91. An elastic assembly 92 is provided between the second housing 2 and the pressure plate 91, preferably a spring. When the ultrasonic transducer assembly 4 drives the cutting head 5 to move downward, the pressure plate 91 drives the spring to move upward to press against the material to be cut, and the cutting head 5 cuts. After cutting is completed, the pressure plate 91 returns to its original position as the spring moves downward.

[0086] The outer wall of the second housing 2 away from the end of the ultrasonic transducer assembly 4 is also provided with a second guide groove 22. The pressure plate 91 is connected to the second guide groove 22 through the sliding column 23. When the ultrasonic transducer assembly 4 drives the cutter head 5 to move downward, the pressure plate 91 moves upward along the direction of the second guide groove 22 with the sliding column 23 to press against the material to be cut. The cutter head 5 cuts. After the cutting is completed, the pressure plate 91 moves downward along the second guide groove 22 with the sliding column 23 to reset.

[0087] The top diameter of the pressure plate 91 is smaller than the bottom diameter, which increases the contact area between the pressure plate 91 and the fabric to be cut, making cutting easier.

[0088] The first housing 1 and the second housing 2 are threadedly connected, and the ultrasonic transducer assembly 4 and the cutter head 5 are threadedly connected.

[0089] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
