The cutter wheel can be rotated between the cutter wheel frame and the lower bracket, and is used for cutting arc-shaped fabrics in a cutting machine. Due to the effect of resistance, the cutter wheel rotates between the bearing inside the lower bracket and the cutter wheel frame, and the edge of the cutter disc is always in contact with the fabric, which can easily cut the arc. The cutter disc is slightly larger than the outer diameter of the outer wheels on both sides. However, during the cutting process, the excess material cut off has the defect of sticking to the ultrasonic cutter, affecting the cutting function of the ultrasonic cutter, requiring timely cleaning, and reducing production efficiency.

DETAILED DESCRIPTION

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] In this disclosure, terms such as "first," "second," "upper," and "lower" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features designated as "first," "second," "upper," and "lower" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions of various embodiments may be combined, but this must be achievable by persons of ordinary skill in the art. If the technical solutions of various embodiments can be combined, they are within the scope of protection claimed by this disclosure.

[0050] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0051] like Figures 1 to 3 As shown, an ultrasonic cutter wheel with automatic material removal includes a cutter body 100, a cutter head 200, and a chip removal channel 300. The cutter body 100 is disc-shaped. The cutter head 200 is disposed on the outer circumference of the cutter body 100, with the outer end of the cutter head 200 forming a cutting edge. The chip removal channel 300 has one end connected to the cutting edge and the other end connected to the exterior of the cutter body 100.

[0052] The blade body 100, serving as the base of the blade wheel, is disc-shaped. A mounting hole 110 is provided at the center of the blade body 100, and multiple fixing holes 120 are evenly distributed around the mounting hole 110. The blade wheel is mounted on the ultrasonic cutting device via the mounting hole 110. The fixing holes 120 further secure the blade wheel and restrict its rotation relative to the mounting axis, achieving synchronized rotation between the blade wheel and the mounting axis of the ultrasonic device. In a first embodiment, the blade head 200 is mounted on the outer circumference of the blade body 100 and can be annularly sleeved around the outer circumference to form a 360° integral blade head 200. In a second embodiment, a small blade head 200 can also be provided, fixed to the outer circumference of the blade body 100. There can be one or more small blade heads 200, with the multiple blade heads 200 evenly distributed around the outer circumference of the blade body 100. Regardless of the embodiment of the blade head 200, the outer circumference of the blade head 200 forms a cutting edge surface, used for cutting fabric. In this embodiment, the second embodiment is preferred. By setting a chip removal channel 300 on the cutter wheel, one end of the chip removal channel 300 is connected to the blade surface, and the other end is connected to the outside of the cutter body 100. During the cutting process, the cut material is promptly removed through the chip removal channel 300, avoiding the excess cut material from sticking to the ultrasonic cutter, improving the cutting function of the ultrasonic cutter, eliminating the need for timely cleaning, and improving production efficiency.

[0053] Furthermore, the chip discharge channel 300 includes a chip entry portion 310 and a chip exit portion 320 . The chip entry portion 310 extends from the blade toward the tool body 100 . The chip exit portion 320 is disposed on the tool body 100 . The chip entry portion 310 and the chip exit portion 320 are in communication.

[0054] When cutting, the blade cuts the cloth, and the cut material enters the chip discharge channel 300 through the chip input portion 310 at the same time. As the cut material increases, it moves along the chip discharge channel 300 toward the cutter body 100 and is discharged to the outside of the pulley through the chip discharge portion 320.

[0055] The chip removal channel 300 can be arranged on the side of the cutter wheel, and the whole is groove-shaped, and can be arranged on one side of the cutter wheel, or on both sides of the cutter wheel. The chip removal channel 300 can also be arranged inside the cutter wheel, and the whole is hole-shaped.

[0056] Preferably, the chip entry portion 310 is a straight hole extending from the blade surface toward the interior of the cutter body 100 , and the chip exit portion 320 is a straight hole with at least one end extending to the side surface of the cutter body 100 .

[0057] In this embodiment, the second embodiment is preferably adopted, that is, the chip removal channel 300 is disposed inside the cutter wheel. Specifically, the straight hole of the chip entry portion 310 extends from the cutting edge toward the interior of the cutter body 100, and the straight hole of the chip exit portion 320 is disposed in the cutter body 100. The straight holes of the two portions can be at any angle. Preferably, the axis of the chip entry portion 310 is perpendicular to the axis of the mounting hole 110, and the axis of the chip exit portion 320 is parallel to the axis of the mounting hole 110. The chip exit portion 320 can be a blind hole connected to one side of the cutter body 100, or a through hole extending to both sides of the cutter body 100 and connected to the outside.

[0058] Preferably, the chip discharge portion 320 is communicated with two opposite side surfaces of the cutter body 100 .

[0059] Preferably, the chip discharge portion 320 is a through hole extending to both sides, which is more conducive to the discharge of the cut materials.

[0060] Furthermore, the connection position between the chip input portion 310 and the chip output portion 320 is rounded or chamfered.

[0061] Chamfering or rounding the connection position between the chip inlet portion 310 and the chip outlet portion 320 is beneficial to the discharge of the material, and avoids the connection position from cutting off the material and blocking the chip discharge channel 300.

[0062] Furthermore, the axis of the chip input portion 310 is perpendicular to the axis of the cutter body 100 , and the axis of the chip output portion 320 is parallel to the axis of the cutter body 100 .

[0063] The arrangement of the chip input portion 310 and the chip discharge portion 320 of this embodiment is conducive to the discharge of materials.

[0064] Furthermore, the cutter head 200 is in a truncated cone shape, and the outer diameter of the cutter head 200 gradually decreases along the extension direction from the connection between the cutter head 200 and the cutter body 100 to the end face of the cutter head 200. The blade surface is a curved surface, a conical surface, a flat surface or an irregular surface.

[0065] The blade head 200 can be of any shape, but a truncated cone is preferred. The blade surface is provided with a chip entry hole, and the blade needs to be sharp enough, which necessitates a thinner wall thickness at the end of the chip entry hole at the blade surface. While a cylindrical blade head 200 would increase sharpness, it would also reduce its strength, making it difficult to apply force during cutting. A truncated cone shape enhances its strength.

[0066] The blade surface can be configured in various shapes, specifically depending on the cutting effect, cutting process requirements, and processing pattern requirements. For example, if a specially designed hollow pattern is required, the blade surface shape can be customized accordingly. However, the blade surface must be completely enclosed, without openings or breaks. The blade surfaces of each cutter head 200 must be located on a circumferential surface with the same diameter around the center axis of the cutter wheel.

[0067] The cutter head 200 and the cutter body 100 can be integrally formed, but this is not easy to manufacture. Preferably, the cutter head 200 is fixed to the cutter body 100 by welding or other methods.

[0068] Further, such as Figure 4 As shown, the inner diameter of the chip entry portion 310 is d, d≥2.5mm. The distance between the port edge of the chip entry portion 310 and the outer edge of the blade surface is the blade, and the blade width is t, 0.05mm≤t≤0.4mm.

[0069] With the above parameter settings, an aperture of 2.5mm or more ensures smooth discharge of materials, and the width of the blade can ensure the sharpness of the blade.

[0070] Furthermore, the height of the cutter head 200 is E, 2mm≤E≤8mm. The depth of the chip entry portion 310 is H, and the thickness between the hole wall of the chip exit portion 320 and the outer periphery of the cutter body 100 is M, H=E+M, 2mm≤M≤10mm.

[0071] By setting the parameters within the above range, the height of the cutter head 200 can ensure the strength and cutting effect of the cutter head 200. The thickness M can ensure the strength of the chip discharge portion 320.

[0072] Furthermore, the inner diameter of the chip discharge portion 320 is D, D=d+f, f is a compensation value, 2mm≤f≤8mm.

[0073] The compensation value establishes a dimensional relationship between the aperture of the chip entry portion 310 and the aperture of the chip exit portion 320 , so that the chip removal achieves the best effect.

[0074] In relation to the above relationship, the thickness of the blade body 100 is preferably 4-50 mm.

[0075] The processing method of the ultrasonic cutter wheel includes:

[0076] S100, selecting a disc-shaped blank for a cutter body and a cylindrical blank for a cutter head, and heat treating the disc-shaped blank and the cylindrical blank;

[0077] S200, machining two side surfaces of the disc-shaped blank on a milling machine, machining mounting holes, fixing holes, and a chip discharge portion on a drilling machine, machining at least one plane corresponding to the cutter head on the outer circumference of the disc-shaped blank, and machining a pre-drilled hole d' extending from the chip feed portion in the cutter body on the plane to a depth sufficient to connect with the chip discharge portion;

[0078] S300, processing the outer peripheral surface of the cylindrical blank into a truncated cone shape, pre-drilling a central through hole on the end surface of the cutter head, wherein the diameter of the pre-drilled central through hole is d"=d';

[0079] S400, welding the cutter head to the plane of the outer peripheral surface of the cutter wheel, ensuring that the coaxiality of the pre-drilled center through hole and the extended pre-drilled hole is within a preset threshold range;

[0080] S500, clamping the welded cutter wheel with a clamping device, and fixing it vertically on the platform of the drilling machine so that the axis of the chip feeding part of one cutter head is perpendicular to the platform, and machining the chip feeding part aperture to the designed size;

[0081] S600, rotating the cutter wheel until the axis of the chip feeding part of the adjacent cutter head is perpendicular to the platform, and repeating step S500 until all chip feeding parts are processed;

[0082] S700, remove burrs and clean the cutter wheel.

[0083] When machining a straight hole in the chip entry portion, the cutter wheel needs to be fixed vertically on the platform of the drilling machine. In order to facilitate machining of the chip entry portion, a special clamping device is required to clamp the cutter wheel for machining. The clamping device 400 can be designed according to actual conditions. Figure 5 and Figure 6As shown, in this embodiment, a clamping device 400 is preferably provided, comprising: a clamping assembly and a clamping shaft 430. The clamping assembly is provided with a central mounting hole, which cooperates with the mounting hole of the cutter wheel, and a plurality of limiting holes 422 are evenly distributed around the central mounting hole, which cooperate with the fixing holes of the cutter wheel. The clamping assembly comprises: a clamping bracket 410 and a clamping disk 420. The clamping bracket 410 is provided with a bracket central mounting hole, and a plurality of positioning holes are provided around the bracket central mounting hole, and the plurality of positioning holes are evenly distributed on a circumference of the same diameter centered on the center of the bracket central mounting hole. The clamping disk 420 is provided with a clamping disk central mounting hole 421, and the clamping disk central mounting hole 421 and the bracket central mounting hole combine to form the central mounting hole. Pins 423 are provided around the clamping disk central mounting hole 421, and the pins 423 cooperate with the positioning holes. A plurality of limiting holes 422 are provided around the central mounting hole 421 of the clamping plate. These limiting holes 422 mate with the fixing holes of the cutter wheel. Bolts passing through at least three of these limiting holes 422 and the fixing holes secure the cutter wheel to the clamping plate 420. A clamping shaft 430 mates with the central mounting hole. The cutter wheel is clamped relative to each other by two clamping assemblies. The clamping shaft 430 passes through the central mounting hole and the cutter wheel's mounting hole, with nuts at both ends screwed into the clamping shaft 430 for clamping.

[0084] During processing, the cutter wheel is fixed to the clamping plate 420 by means of bolts passing through the fixing holes and the limiting holes 422 of the two clamping plates 420. The cutter head to be processed is facing upwards, and the pin 423 is passed through a positioning hole of the clamping bracket 410 to ensure that the axis of the chip feed portion of the cutter head to be processed is perpendicular to the drilling platform. After the cutter wheel is fixed by the clamping shaft 430, it is fixed on the drilling machine and the chip feed portion of the cutter head is processed. After processing one chip feed portion, the clamping device 400 is released, and the two clamping plates 420 are rotated so that the axis of the chip feed portion of the adjacent cutter head is perpendicular to the drilling platform. The cutter wheel is re-clamped and the next chip feed portion is processed according to the above steps. The chip feed portions of all cutter heads are processed in this way.
