Figures 2 to 5 Provide a detailed description.
[0028] This embodiment provides a forming milling cutter for machining liquid-cooled module connectors. The forming milling cutter includes a cutter body 9 and cutting edges and chip removal grooves disposed on the cutter body 9. The cutting edges include a first cutting edge 1, a first bevel cutting edge 2, a second cutting edge 3, a third cutting edge 4, a fourth cutting edge 5, a second bevel cutting edge 6, a fifth cutting edge 7, and a third bevel cutting edge 8 arranged sequentially from the cutter tip. The diameters of the first cutting edge 1, the second cutting edge 3, the fourth cutting edge 5, and the fifth cutting edge 7 gradually increase. The first bevel cutting edge 2, the second bevel cutting edge 6, and the third bevel cutting edge 8 are respectively provided with different included angles with the centerline of the cutter body 9.
[0029] Specifically, the dimensional parameters of each cutting edge and bevel edge are designed as follows: the diameter of the first cutting edge 1 is 2.3mm, and the cutting length of the first cutting edge 1 is 1.03mm; the diameter of the second cutting edge 3 is 5.5mm, and the cutting length of the second cutting edge 3 is 3.7mm; the third cutting edge 4 is set as a C 0.3 cutting edge; the diameter of the fourth cutting edge 5 is 8.25mm, and the cutting length of the fourth cutting edge 5 is 5.64mm; the diameter of the fifth cutting edge 7 is 9.5mm, and the cutting length of the fifth cutting edge 7 is 3.36mm; the angle between the first bevel edge 2 and the center line of the tool body 9 is 30°, the angle between the second bevel edge 6 and the center line of the tool body 9 is 45°, and the angle between the third bevel edge 8 and the center line of the tool body 9 is 25°.
[0030] In one embodiment, the sharp corner of the fourth cutting edge 5 is rounded with an outer radius of R0.2.
[0031] In one embodiment, the forming milling cutter has 2 to 4 teeth and 2 to 4 chip removal grooves.
[0032] In one embodiment, the chip removal groove is clockwise around the cutter body 9, and the helix angle of the chip removal groove is set to 15° to 45°. Preferably, the forming milling cutter has two teeth and two chip removal grooves, wherein the chip removal groove is clockwise around the cutter body 9 with a helix angle of 15°.
[0033] In one embodiment, each of the different cutting edges of the forming milling cutter is provided with a microgroove.
[0034] The forming milling cutter of this invention is made entirely of high-hardness, high-wear-resistant cemented carbide material. The milling cutter mainly consists of a cutter body 9, cutting edges, and a chip removal groove assembly. The cutter shank is connected to the tool holder. The cutter body 9 is equipped with multiple precision-formed cutting edges. The shape and distribution of the cutting edges are designed according to the specific structure of the liquid-cooled module connector, and the outer contour of the cutting edges matches the inner cavity contour of the liquid-cooled module connector, ensuring that complex shapes can be machined in a single pass.
[0035] Cutting edge design: The shape of the cutting edge is precisely calculated and optimized to reduce cutting force, lower cutting temperature, and improve machining accuracy and surface quality.
[0036] Chip removal groove design: The cutting edge and the cutter body are equipped with rationally designed chip removal grooves in 9 parts to effectively remove chips and coolant generated during the cutting process, prevent chip accumulation and blockage, and maintain the cleanliness and cooling effect of the cutting area. The shape and size of the chip removal grooves are optimized according to the layout and parameters of the cutting edge.
[0037] The working principle of the forming milling cutter for machining liquid cooling module connectors in this application is as follows: based on the contour dimensions of the internal cavity structure of a liquid cooling module connector as a standard, a forming milling cutter with matching external contour features is designed and manufactured. Multiple cutting edge structures are integrated into one milling cutter, and all radial dimensions of the milling cutter are about 1mm smaller than the actual contour dimensions. Then, the milling cutter and the tool holder are installed together into the spindle, and the milling cutter is rotated in the forward direction. Helical milling is used for roughing, and finally, finishing is performed.
