Description

Technical Field

[0001] This invention relates to the field of cutting tool technology, and more specifically, to a high-frequency ultrasonic cutting tool without overload compensation. 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 pricking, and the pricking points are connected to form a line for cutting. This method is prone to producing burrs during cutting and cannot seal the edges, so further processing is required after cutting, which increases production costs. Alternatively, an improved cutting device (publication number: CN115070072A) can be used to reduce and avoid material breakage and burrs at the cut. However, the blade of this device is a beveled blade, which requires excessive downward movement to complete the cutting of thick fabrics, and still cannot achieve efficient cutting.

[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] In view of this, the present invention proposes a cutting method that is simple in structure and highly efficient, without overload compensation.

[0007] A high-frequency ultrasonic cutting tool without overload compensation. Summary of the Invention

[0008] To address the problems of low cutting efficiency and the need for overload cutting in existing technologies, this invention proposes a high-frequency ultrasonic cutting tool without overload compensation. The tool includes a first housing 1, a second housing 2, an electric slip ring 3, an ultrasonic transducer assembly 4, a vertical cutting head 5, and a gas supply mechanism. The first housing 1 has an electric slip ring 3 at one end, with a hollow structure in the middle. The second housing 2 is located at the other end of the first housing 1. The ultrasonic transducer assembly 4 is housed 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. The hollow structure in the middle of the electric slip ring 3 is connected to a gas supply mechanism, which supplies air downwards to dissipate heat from the ultrasonic transducer assembly 4 and the vertical cutting head 5. The vertical cutting head 5 is connected to the end of the ultrasonic transducer assembly 4 furthest from the electric slip ring 3. The ultrasonic transducer assembly 4 and the vertical cutting head 5 work together to replace traditional piercing techniques. Furthermore, the downward movement of the vertical cutting head 5 corresponds to the fabric thickness, eliminating the need for excessive cutting, thus improving production efficiency. The gas supply mechanism further enhances heat dissipation efficiency and reduces the tool failure rate.

[0009] A high-frequency ultrasonic cutting tool without overload compensation includes a first housing 1, a second housing 2, an electric slip ring 3, an ultrasonic transducer assembly 4, a vertical cutting head 5, and a gas supply mechanism.

Each first cutting surface 531 and each second cutting surface 532 forms a first cutting edge 533. Each first cutting surface 531, each second cutting surface 532, and the third cutting surface form a second cutting edge 534.

[0012] 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 second housing 2 away from the vertical 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.

[0013] 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 vertical cutter head 5 from the inside to the outside during processing.

[0014] In some embodiments, the second housing 2 has a plurality of second ventilation holes 21 spaced apart near the vertical cutter head 5 on its side wall, for dissipating heat generated by the ultrasonic transducer assembly 4 and the vertical cutter head 5 from the inside to the outside during processing.

[0015] In some embodiments, an auxiliary positioning mechanism 6 is detachably connected to the outer wall of the first housing 1 to assist the vertical cutter head 5 in adjusting the cutting edge. The auxiliary positioning mechanism 6 is also connected to the external cutting machine mounting port. The side wall of the first housing 1 away from the second housing 2 is provided with at least one adjustment groove 7. 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 correspondingly 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.

[0016] In some embodiments, the fixing component 61 includes a fixing strip 63 and screws. The fixing strip 63 has a first guide groove on its inner side. 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. The positioning block 62 can be adjusted in position along the adjustment groove 7 and the first guide groove. A positioning point is provided at the center line of the front part of the positioning block 62. When the vertical cutter head 5 is parallel or perpendicular to the positioning point, the vertical cutter head 5 is installed correctly.

[0017] 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 8. The pre-compression assembly 8 is used to protect the vertical cutter head 5 and to pre-press the material to be cut during cutting, so that the vertical cutter head 5 can cut. The pre-compression assembly 8 includes a pressure plate 81, an elastic component 82, and a second guide groove 83. 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 81. An elastic component 82, preferably a spring, is provided between the second housing 2 and the pressure plate 81. The outer wall of the end away from the ultrasonic transducer assembly 4 is provided with a second guide groove 83. The pressure plate 81 is connected to the second guide groove 83 through a sliding column 84. When the ultrasonic transducer assembly 4 drives the vertical cutter head 5 to move downward, the pressure plate 81 moves upward along the direction of the second guide groove 83 along with the sliding column 84 to press the material to be cut. The vertical cutter head 5 cuts. After cutting, the pressure plate 81 moves downward along the second guide groove 83 along with the spring and the sliding column 84 to reset.

[0018] Furthermore, the top diameter of the pressure plate 81 is smaller than the bottom diameter, which increases the contact area between the pressure plate 81 and the fabric to be cut, making cutting easier.

[0019] Furthermore, the first housing 1 and the second housing 2 are threaded together, and the ultrasonic transducer assembly 4 and the vertical cutter head 5 are threaded together.

The first housing 1 has an electric slip ring 3 at one end, with a hollow structure in the middle. The second housing 2 is located at the other end of the first housing 1. The ultrasonic transducer assembly 4 is housed 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 gas supply mechanism is connected to the hollow structure in the middle of the electric slip ring 3. The gas supply mechanism supplies air downwards to dissipate heat from the ultrasonic transducer assembly 4 and the vertical cutting head 5. The vertical cutting head 5 is connected to the end of the ultrasonic transducer assembly 4 furthest from the electric slip ring 3. The ultrasonic transducer assembly 4 and the vertical cutting head 5 work together to replace traditional piercing. Simultaneously, the downward movement of the vertical cutting head 5 is equal to the fabric thickness, eliminating the need for excessive cutting, thus improving production efficiency. Furthermore, the gas supply mechanism further enhances heat dissipation efficiency and reduces the tool failure rate. Attached Figure Description
