Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, and more specifically, to a three-edged U-shaped groove aluminum coated milling cutter. Background Art

[0002] Three-edge milling cutter usually refers to three-edge milling cutter, which is a milling cutter with three cutting edges. These cutting edges are distributed on the circumference and two end faces of the milling cutter, thereby improving cutting conditions, increasing cutting efficiency and reducing surface roughness. It is mainly used for milling the step surface and groove surface of metal materials with medium hardness and strength. Three-edge milling cutter is used for milling the step surface and groove surface of difficult-to-cut materials. It is mainly used for milling grooves of fixed size, and can also mill general grooves and step surfaces.

[0003] In actual use, three-edge milling cutters are usually used to process U-shaped aluminum grooves on the market due to the special structure of the three-edge milling cutter. When using a milling cutter to process a workpiece, the toughness of the milling cutter must be considered first. Generally speaking, the number of chip grooves determines the toughness of the milling cutter. The larger the chip groove, the lower the toughness of the milling cutter. The function of the chip groove is to smoothly discharge the chips generated during the milling process. Therefore, although a chip groove that is too small can increase the toughness, its chip removal function will be greatly reduced.

[0004] However, the three-edge milling cutters on the market have the problem of chips stacking in the chip grooves and not curling normally, which leads to uneven chip removal and affects the milling cutter processing effect. How to reasonably control the toughness of the milling cutter and the number of chip grooves is an important part of the milling cutter design process. In order to ensure both toughness and chip removal, the depth and shape of the chip grooves can be controlled without increasing the number of chip grooves. By using chip grooves of appropriate size and shape, the chips accumulated in the chip grooves will not stack up and can be discharged naturally, thereby improving the milling cutter processing effect. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a three-edge U-groove coated milling cutter for aluminum with a reasonably set chip groove shape, thereby ensuring the toughness of the three-edge milling cutter without affecting the chip removal effect, thereby further improving the processing effect of the three-edge milling cutter.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A three-edged U-groove coated milling cutter for aluminum comprises a cutter head assembly, one end of the cutter head assembly is provided with a cutter neck assembly, and the end of the cutter neck assembly away from the cutter head assembly is provided with a cutter handle assembly; the cutter head assembly comprises a cutter head core arranged in a horizontal direction; the cutter neck assembly comprises a cutter neck body connected to the cutter handle assembly and adapted to the shape of the cutter handle assembly.

[0008] The utility model is further configured as follows: the cutter head assembly is arranged in a horizontal direction, the length of the cutter head assembly is set to a, the value of a is set to 18±0.15mm, the width of the cutter head assembly is set to e, the value of e is 6±0.2mm; the cutter head core is arranged in a cylindrical shape, and three groups of cutter head blades are arranged on the outside of the cutter head core, and the three groups of cutter head blades are arranged in a circular array along the outer side wall of the cutter head core, and a group of chip removal grooves are arranged on the recessed side of each group of cutter head blades.

[0009] The utility model is further configured as follows: the blade of the cutter head is provided with a blade angle along the axial surface, the blade angle is set as an acute angle, a bottom blade is provided at the bottom of the blade angle, the bottom blade is arranged along the vertical direction, and a bottom blade groove is provided at one end of the bottom blade away from the blade angle.

[0010] By adopting the above technical solution, the blade of the cutter head is provided with a blade angle along the axial surface, and the blade angle is set to an acute angle, which is the angle between the cutting edge and the base surface. Increasing the angle of the blade angle can make the cutting edge sharper, reduce cutting force and cutting heat, and improve the quality of the machined surface. However, an excessively large blade angle may reduce the strength of the blade. Therefore, by setting the blade angle reasonably, the blade strength can be ensured while fine processing is performed on the workpiece surface. A bottom blade is provided at the bottom of the blade angle, and the bottom blade is arranged in the vertical direction. In the actual production process, the bottom blade is arranged parallel to the workpiece surface, ensuring that the bottom blade can perform precise cutting on the workpiece surface.

The tool return neck can serve as an auxiliary chip discharge channel to help chips be discharged from the cutting area to prevent chip blockage and accumulation, and, during the milling process, the tool return neck helps to reduce vibration because they can reduce the rigidity of the contact between the milling cutter and the workpiece.

[0015] The utility model is further configured as follows: the length of the handle assembly is set to b, the value of b is 50±0.3 mm, the diameter of the handle assembly is set to c, the value of c is 6±0.006 mm;

[0018] 1. The blade of the cutter head is provided with a knife angle along the axial surface. The knife angle is set to an acute angle. The knife angle is the angle between the cutting edge and the base surface. Increasing the angle of the knife angle can make the cutting edge sharper, reduce cutting force and cutting heat, and improve the quality of the machined surface. However, an excessively large knife angle may reduce the strength of the blade. Therefore, a reasonably set knife angle can ensure the strength of the blade while performing fine processing on the workpiece surface. A bottom blade is provided at the bottom of the knife angle. The bottom blade is set in the vertical direction. In the actual production process, the bottom blade is set parallel to the workpiece surface, ensuring that the bottom blade can perform precise cutting on the workpiece surface.
