[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Figures 1-5 This application provides a manufacturing process for a heat-dissipating cutter head 100. The manufacturing process of the heat-dissipating cutter head 100 is applied to the heat-dissipating cutter head 100. The heat-dissipating cutter head 100 is used to reduce the heat of the cutter head body 10. The heat-dissipating cutter head 100 includes a cutter head body 10 and an insert 20. The insert 20 is disposed on the inner side of the cutter head body 10.

[0026] In the first embodiment, the cutter head body 10 serves as a support component of the heat-dissipating cutter head 100. The cutter head body 10 supports the insert 20, which is embedded in the cutter head body 10 and close to the cutter head end of the cutter head body 10, so that the insert 20 can be fixed to the cutter head body 10. The cutter head end of the cutter head body 10 is arranged in a serrated shape. The insert 20 is made of a high thermal conductivity material and exchanges heat with the cutter head body 10 to conduct heat to the external environment, so that the heat of the cutter head body 10 can be conducted to the external environment through the insert 20, thereby facilitating heat dissipation of the cutter head body 10, avoiding excessive temperature of the cutter head body 10, and improving the heat dissipation effect of the heat-dissipating cutter head 100.

[0027] The cutter head body 10 is provided with an embedding groove 10a, which is recessed from top to bottom by the cutter head body 10. The embedding groove 10a is formed based on the slot of the cutter head body 10. An insert 20 is embedded in the embedding groove 10a. The outer contour of the insert 20 is adapted to the inner contour of the embedding groove 10a. The insert 20 and the cutter head body 10 exchange heat so that the insert 20 can be embedded into the cutter head body 10 through the embedding groove 10a. This facilitates the heat of the cutter head body 10 to be conducted to the external environment through the insert 20, thereby facilitating the heat dissipation of the cutter head body 10 and avoiding excessive temperature of the cutter head body 10. This improves the heat dissipation effect of the heat-dissipating cutter head 100.

[0028] The thermal grease is located between the cutter head body 10 and the insert 20, and contacts both the cutter head body 10 and the insert 20, so that the cutter head body 10 and the insert 20 conduct heat through the thermal grease. At this time, the lower surface of the thermal grease contacts the cutter head body 10, and the upper surface of the thermal grease contacts the insert 20, so that the heat of the cutter head body 10 can be conducted to the insert 20 through the thermal grease, thereby achieving heat dissipation of the cutter head body 10.

[0029] The embedding groove 10a includes multiple sub-embedded grooves 10b, which are connected along the length of the insert 20. The insert 20 is inserted into the embedding groove 10a in the front-back direction and fills the multiple sub-embedded grooves 10b. By arranging multiple sub-embedded grooves 10b, the embedding effect between the insert 20 and the embedding groove 10a is increased, thereby facilitating the improvement of the connection stability between the insert 20 and the cutter head body 10.

[0030] The surface of the cutter head body 10 is flush with the surface of the insert 20, which improves the aesthetics between the cutter head body 10 and the insert 20.

[0031] The cutter head body 10 is provided with a first connecting hole 10c, and the insert 20 is provided with a second connecting hole 20a. The first connecting hole 10c and the second connecting hole 20a are arranged opposite to each other. The first connecting hole 10c and the second connecting hole 20a are used to connect the electric pusher body of the power supply induction generator.

[0032] In the second embodiment, the manufacturing process of the heat-dissipating cutter head 100 includes: Step S111: Use a machining center to slot the cutter head body 10; Step S112: Heat treat the slotted cutter head body 10, and cut the insert 20 using wire cutting. Step S113: The insert 20 is leveled and ground. Step S114: Press the insert 20 into the slotted cutter head body 10 and fill it with thermal grease; Step S115: Perform cutting edge treatment on the grooved cutter head body 10.

[0033] Optionally, the cutter head body 10 may be slotted using a machining center, including: A punch press is used to punch and blank 1-15mm stainless steel sheets to form flat plates; The blanking plate is leveled using a double-end surface grinder to output the cutter head body 10; the accuracy is guaranteed to be 2-20uM to ensure the stability of subsequent inlay and the yield of grinding. After leveling on a double-end grinding machine, the cutter head body 10 is grooved using a machining center.

[0034] Optionally, grooving the cutter head body 10 using a machining center also includes: First, rough-cut the 1-15mm cutter head body with a coarse cutting edge. Then, use a tool with a cutting edge of at least 16 to perform a second fine milling to ensure that the surface Ra is less than or equal to 0.8. Finally, use a ceramic brush to perform mirror grinding to further increase the contact surface area.

[0035] Optionally, the slotted cutter head body 10 is heat-treated, and the insert 20 is cut using wire EDM, including: The slotted cutter body 10 is hardened by quenching to remove internal stress, so as to ensure that the HRC hardness of the cutter is greater than or equal to 50. The insert 20 is cut using wire cutting to ensure that the positive and negative tolerance of the contour is no more than 50um, so as to meet the requirements for further embedding on the substrate surface.

[0036] Optionally, the insert 20 may be leveled and ground, including: The insert 20 is leveled to ensure a good fit with the bottom of the cutter head body 10; the workpiece height is ground to 3.12mm using a double-end face grinder, and then a single-sided grinder is used to ensure that the surface Ra is not higher than 1.6 and the end face error is not higher than 0.01mm.

[0037] Optionally, the insert 20 is pressed into the slotted blade body 10 and filled with thermal grease, including: The insert 20 is pressed into the slotted cutter body 10 and filled with thermal grease to increase heat transfer efficiency.

[0038] Optionally, the grooved cutter head body 10 may undergo edge treatment, including: The end of the slotted cutter head body 10 is treated with a cutting edge; The cutting edge is ground, and at the same time, the insert 20 is surface ground to make the surface of the heat dissipation type cutter head 100 flat and the edge sharpened. The heat-dissipating blade 100 is ultrasonically cleaned.

[0039] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a manufacturing process for a heat-dissipating cutter head 100. The heat-dissipating cutter head 100 includes a cutter head body 10 and an insert 20. The insert 20 is embedded in the cutter head body 10 and close to the cutter head end of the cutter head body 10.
