Description

Technical Field

[0001] This utility model relates to the field of milling technology, specifically to an unequal pitch end mill for machining aluminum alloy products. Background Technology

[0002] Aluminum alloy product processing is a process based on the properties of aluminum alloy materials, which transforms them into products with specific shapes, properties and functions through a series of processes. Milling is required when processing aluminum alloy products. Milling is a machining method that uses a rotating milling cutter to cut the desired shape and size into a workpiece. Through the rotation of the milling cutter and the movement of the workpiece, the cutting edge of the milling cutter removes the workpiece material one by one, forming geometric features such as planes, grooves, and curved surfaces. When milling aluminum alloys, existing end mills generate a lot of heat due to high-speed cutting. The end mills lack efficient heat dissipation structures, making it difficult to dissipate the heat quickly. This leads to a sharp rise in tool temperature. Excessive temperature not only accelerates tool wear, significantly shortens tool life, and increases production costs, but also causes tool thermal deformation, resulting in a decrease in machining accuracy and failing to meet the machining requirements of aluminum alloy products. Therefore, an unequal pitch end mill for machining aluminum alloy products is proposed. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an unequal pitch end mill for machining aluminum alloy products. It solves the problem that due to the large amount of heat generated during high-speed cutting, the end mill lacks an efficient heat dissipation structure, making it difficult to dissipate heat quickly, which leads to a sharp increase in tool temperature. Excessive temperature not only accelerates tool wear, significantly shortens tool life, and increases production costs, but also causes tool thermal deformation, resulting in a decrease in machining accuracy and failure to meet the machining requirements of aluminum alloy products.

[0004] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: including a tool holder and an end mill head with unequal tooth pitch provided on the outer wall of the tool holder, wherein a heat dissipation mechanism is provided on the inner side of the tool holder and a milling mechanism is provided on the outer wall of the tool holder; The heat dissipation mechanism includes a cooling section and a heat-conducting section; The cooling section includes cooling pipes, and the heat-conducting section includes heat-conducting plates; Cooling grooves are provided on the inner side of both the tool holder and the end mill head with unequal tooth pitch. The cooling pipe is located inside the cooling grooves. Multiple heat conduction grooves are provided on the inner side of the end mill head with unequal tooth pitch. The inner walls of the multiple heat conduction grooves are fixedly connected to the outer walls of multiple heat conduction plates. The multiple heat conduction plates extend to the inner wall of the cooling grooves.

[0005] Preferably, the milling mechanism includes multiple unequal pitch bottom milling edges, all of which are located at the end of the unequal pitch end mill head away from the tool holder. The unequal pitch design can effectively reduce the vibration generated during milling and improve the surface quality of the machined part.

[0006] Preferably, the ends of the plurality of heat-conducting plates away from the cooling tank are respectively close to the plurality of unequal pitch bottom milling edges. An mounting plate is fixedly provided on the outer wall of the cooling pipe. The outer wall of the mounting plate is fixedly connected to the inner wall of the cooling tank. The heat-conducting plates are close to the unequal pitch bottom milling edges, which can quickly absorb the heat generated during the milling process and transfer the heat to the cooling tank by themselves.

[0007] Preferably, multiple heat-conducting fins are fixedly provided on the outer wall of the inner side of the cooling groove, and multiple sets of heat dissipation holes are opened through the outer wall of the unequal pitch end mill head. The heat-conducting fins increase the heat conduction area, improve the heat conduction efficiency, and enable heat to be transferred to the cooling groove more quickly.

[0008] Preferably, the outer wall of the unequal pitch end mill head is provided with multiple spiral chip removal grooves, and the outer wall of the unequal pitch end mill head is provided with multiple peripheral milling edges, which are used for milling the side of aluminum alloy products.

[0009] Preferably, multiple crescent grooves are formed between the various unequal pitch bottom milling cutters. The presence of crescent grooves helps to curl and remove chips, further optimizing the milling effect.

[0010] (III) Beneficial Effects This utility model provides an unequal pitch end mill for machining aluminum alloy products. It has the following advantages: (I) The unequal pitch end mill for machining aluminum alloy products has a heat-conducting fin in its heat dissipation mechanism that is close to the bottom milling edge of the unequal pitch end mill. This heat-conducting fin can capture a large amount of heat generated during milling and quickly transfer the heat to the cooling tank. Cooling pipes can be filled with coolant, and through the circulation of the coolant, the heat in the cooling tank can be carried away in time, achieving effective cooling of the tool holder and the end mill head. At the same time, the heat-conducting fins located on the outer wall of the inner side of the cooling tank increase the heat conduction area and improve the heat transfer efficiency, allowing the heat to dissipate more quickly. In addition, multiple sets of heat dissipation holes are opened through the outer wall of the unequal pitch end mill head to further assist in heat dissipation, reduce the tool temperature in all directions, effectively avoid the problem of decreased machining accuracy and shortened tool life caused by tool overheating, and improve the reliability, stability and service life of the tool during the machining process.

[0011] (II) This unequal pitch end mill for machining aluminum alloy products features a spiral chip removal groove in its milling mechanism. This groove allows for rapid and smooth chip removal during milling, effectively preventing chip accumulation in the machining area and avoiding chip scratches on the machined surface. It also reduces friction between the chips and the tool / workpiece, minimizing tool wear. The peripheral milling edge enables efficient milling of the sides of aluminum alloy products, while the unequal pitch bottom milling edge, with its unique unequal pitch design, effectively reduces vibration during milling, improving the flatness and smoothness of the machined surface. The crescent grooves between the unequal pitch bottom milling edges facilitate chip curling and removal, further optimizing the milling effect. These components work together to improve machining efficiency, reduce surface vibration marks and other defects, and meet the requirements for high-precision machining of aluminum alloy products.

[0016] In use, the multiple spiral chip removal grooves 31, peripheral milling edges 32, unequal pitch bottom milling edges 34, and crescent grooves 33 on the unequal pitch end mill head 4 work together to complete the milling of aluminum alloy products. The spiral chip removal grooves 31 can quickly discharge chips during the milling process, preventing chip accumulation from affecting machining accuracy and efficiency; the peripheral milling edges 32 are used to mill the sides of aluminum alloy products, while the unequal pitch bottom milling edges 34 are used to process the bottom.

Cooling pipe 22 located in the cooling groove 23 can be filled with coolant. The coolant flow carries away the heat in the cooling groove 23, thereby cooling the tool holder 1 and the unequal pitch end mill head 4. At the same time, the heat-conducting fins 25 set on the outer wall of the heat-conducting plate 26 on the inner side of the cooling groove 23 increase the heat conduction area and improve the heat conduction efficiency, so that the heat can be transferred to the cooling groove 23 more quickly. Multiple sets of heat dissipation holes 24 through the outer wall of the unequal pitch end mill head 4 can help dissipate heat and further enhance the heat dissipation effect, avoiding the impact on machining accuracy and service life due to excessive end mill temperature.
