Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, and more specifically to a six-blade milling cutter for cutting aluminum alloy materials. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. During operation, each tooth cuts off the excess of the workpiece in turn and intermittently. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. During the processing, the milling cutter generates greater resistance with the cutting piece and thus generates higher temperatures. High temperatures can easily damage the cutting surface and reduce the service life of the milling cutter.

[0003] The existing publication number is CN210755422U, and the patent name is a patent document of a six-blade milling cutter for cutting aluminum alloy materials. It discloses a cooling method that uses the centrifugal force of rotation to throw the coolant entering the cooling tank out from the liquid guide hole to take away the heat of the milling cutter;

[0004] However, during use, because the coolant is thrown out horizontally, it cannot directly contact the blade below. The heat at the blade position can only be transferred to the cooling groove position by utilizing the thermal conductivity of the metal, resulting in poor heat dissipation effect. In view of this, we propose a six-blade milling cutter for cutting aluminum alloy materials. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Example

[0031] This embodiment provides a six-blade milling cutter for cutting aluminum alloy materials. Figure 1 , including a tool holder 3, the tool holder 3 is used as a main body to provide an installation space, a through hole 4 is opened at the edge of the tool holder 3 along the height direction, and the through hole 4 is set at the edge of the tool holder 3 along the height direction, so that the coolant above the tool holder 3 flows down through the through hole 4, and a blade 6 is installed at the mounting seat 5 near the through hole 4. The water outlet pipe of the machine tool is used to directly spray the coolant to the tool holder 3 and the blade 6, so that the coolant can directly contact the blade 6, thereby improving the heat dissipation effect of the blade 6. A fin 2 is installed on the circumferential side wall of the tool holder 3 near the through hole 4. When the tool holder 3 rotates, the fin 2 can collect and guide the coolant centrifugally thrown to the surroundings. The fin 2 allows more coolant to flow to the blade 6 through the through hole 4, further improving the heat dissipation effect.

[0032] In a further embodiment, referring to Figure 1 A tool shaft 1 is installed at one end of the tool holder 3. The tool shaft 1 is perpendicular to the tool holder 3 and is located on the top of the tool holder 3. It is used to connect with the rotating fixture of the machine tool for rotary milling. A mounting seat 5 is installed at the other end of the tool holder 3 located at the tool shaft 1. The mounting seat 5 is used to install a blade 6. The blade 6 can be installed on the side of the tool holder 3 away from the tool shaft 1 to reduce obstruction and facilitate milling processing.

[0033] In a further embodiment, referring to Figure 3 The tool holder 3 includes a main body 31, which adopts a frustum structure, which is narrow at the top and wide at the bottom. The coolant that rushes on the upper part of the main body 31 can be guided downward so that the coolant can flow down smoothly. Among them, the main body 31 is provided with a guide groove 32 at the through hole 4. The guide groove 32 is connected with the through hole 4, which can increase the aperture coverage range of the top of the through hole 4, so that more coolant can flow into the through hole 4, and then more coolant from the top can flow to the blade 6 position, thereby improving the utilization rate of the coolant and achieving better heat dissipation effect.

[0034] In a further embodiment, referring to Figure 2 When the blade seat 3 rotates, the water outlet angle of the coolant is fixed, so the fin 2 will have a water-facing surface and a water-repelling surface. At this time, the rotating fin 2 will block the coolant on the water-facing surface and guide it downward. Among them, the through hole 4 is located on the water-facing surface of the fin 2, so more coolant will enter the through hole 4. Similarly, the blade 6 is located on the water-facing surface of the mounting seat 5, and the blade 6 can be exposed to more coolant, resulting in a better heat dissipation effect.

[0035] In a further embodiment, referring to Figure 2 A groove 21 is provided on one side of the fin 2 close to the through hole 4. The design of the groove 21 can be used to gather more coolant, and the bottom surface of the groove 21 is flush with the opening of the through hole 4, so that the coolant can flow down more smoothly to enter the through hole 4, achieving a better guiding effect.

[0036] In a further embodiment, referring to Figure 2 One side of the fin 2 is fixedly connected to the main body 31, and the integrated connection is more firmly fixed, which improves the connection stability. A convex edge 22 is installed on the side of the fin 2 away from the main body 31, and the convex edge 22 is bent toward the water-facing surface of the fin 2 to wrap around the fin 2 to prevent the coolant collected by the fin 2 from being thrown out horizontally due to centrifugal force, thereby ensuring a better collection and guiding effect of the coolant.

[0037] In a further embodiment, referring to Figure 3 and Figure 4 The mounting seat 5 includes a middle seat 51, which is fixedly connected to the main body 31 to provide a mounting platform, and a bolt hole is provided at the edge of the middle seat 51, so that the blade 6 can be disassembled and assembled more quickly. A convex strip 52 is provided on the water-facing surface of the middle seat 51 near the blade 6. The convex strip 52 is horizontally arranged at the bottom outlet position of the through hole 4, which separates the coolant up and down and evenly guides it to the surface of the blade 6, so that the blade 6 can be cooled in a covering manner to improve the cooling effect.

[0038] In a further embodiment, multiple through holes 4 can be provided, and the fins 2 will also have the same number. The coolant collected by the fins 2 can be directed downward in multiple times to prevent excessive coolant at the position of a single through hole 4, thereby ensuring that the collected coolant can be fully directed downward to improve utilization.

[0039] The machine tools and fixtures involved in the embodiments are existing products produced by Shanghai Yongce Machinery Equipment Co., Ltd., and their supporting control systems, solenoid valves, control switches and circuit pipelines can also be provided by the manufacturer. In addition, the power supply modules, circuits, electronic components and control modules involved in the utility model are all existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and methods.
