Description

Technical Field

[0001] The utility model relates to the technical field of machining cutters, and more specifically, to a honeycomb aluminum plate cutting cutter. Background Art

[0002] Aluminum honeycomb panels are the application of aviation and aerospace materials in the field of civil construction. The core material of aluminum honeycomb panels is aluminum hexagonal honeycombs with low density, which can greatly reduce the building load and cost. The honeycomb structure also has excellent properties of high pressure resistance, shock absorption, sound insulation, heat preservation, flame retardancy and high specific strength. For the modern home furnishing industry with strict environmental protection requirements, using aluminum honeycomb panels as furniture processing materials is a good material choice. Its completely non-toxic green quality allows furniture manufacturers to reduce unnecessary environmental protection procedures when processing furniture. In addition, the panels of aluminum honeycomb panels are more diversified, making them widely used in the furniture industry, and the demand for aluminum honeycomb panel processing has increased. However, due to the low density of aluminum honeycomb panels, a lot of light waste chips will be generated when cutting the materials, so the tool needs to have excellent chip removal and cutting performance to prevent the waste chips from sticking to the tool and the tool from heating up.

[0003] Existing milling cutters, such as patent number: CN220050182U, disclose a three-blade milling cutter for cutting aluminum honeycomb panels. The milling cutter includes a cutter body and a cutter head. The cutter head is provided with three chip grooves arranged in a spiral along its axial direction. The cutter head on one side of each chip groove is formed with spirally arranged cutting circumferential teeth. The inner wall surface of the chip groove includes a first inclined surface, a first curved surface, a second inclined surface and a second curved surface connected in sequence. The inclination of the first inclined surface is greater than the inclination of the second inclined surface, and the radius of the first curved surface is smaller than the radius of the second curved surface. The cutting circumferential teeth are located on the cutter head on the side of the first inclined surface away from the first curved surface. The three-blade milling cutter of the utility model can discharge waste chips well, prevent waste chips from sticking in the spiral groove, and improve the stability and life of the tool.

[0004] The above-mentioned existing milling cutter is a three-blade milling cutter with three chip grooves and three cutting edges. With such a structure, the volume of the chip groove between two adjacent cutting edges will become smaller, which may easily lead to the problem of uneven chip removal, especially for the processing of honeycomb aluminum plates, which has a greater impact on the chip removal effect; and the structure composed of multiple connected surfaces of the chip groove is also difficult to process and the cost is relatively high.

[0005] Therefore, a novel honeycomb aluminum plate cutting knife is proposed to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a honeycomb aluminum plate cutting tool for the above-mentioned deficiencies in the prior art, which can improve the chip removal effect of the tool, reduce the tool processing difficulty, and thus reduce the tool cost.

[0007] The technical solution of the utility model is as follows: a honeycomb aluminum plate cutting tool comprises a tool body and a tool head, the tool head is provided with a chip groove arranged spirally along its axial direction, a spirally arranged cutting circumferential teeth are formed on the tool head on one side of the chip groove, and at least two shovel backs are provided on the tool head on the side of the cutting circumferential teeth away from the chip groove, the volume of the chip groove is 1 / 4 to 1 / 2 of the volume of the tool head, and the inner wall cross-section of the chip groove is an arc surface.

[0008] As a further improvement, the cross-sectional width of each shovel back is the same.

[0009] Furthermore, the volume of the chip groove is 1 / 3 of the volume of the cutter head.

[0010] Furthermore, a cutting end tooth is provided at an end portion of the cutter head away from the cutter body, and the cutting end tooth is located at an end edge of the chip removal groove.

[0011] Furthermore, a first end tooth clearance angle is provided on the rear side of the cutting end tooth, and a second end tooth clearance angle is provided on the cutter head on the rear side of the first end tooth clearance angle.

[0012] Furthermore, the first end tooth back angle and the second end tooth back angle are the same, and are both greater than 0° and less than or equal to 50°.

[0013] Furthermore, the front angle α and the back angle β of the cutting peripheral teeth are both greater than 0° and less than or equal to 50°.

[0014] Furthermore, the helix angle μ of the chip removal groove is greater than 0° and less than or equal to 80°.

[0015] Furthermore, the blade body and the blade head are an integrated structure, and the blade body and the blade head are coaxially arranged.

[0016] Furthermore, the diameter of the blade body is greater than the diameter of the blade head, and the diameter of the blade head is 4 mm to 16 mm.

[0017] Beneficial Effects

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The honeycomb aluminum plate cutting tool of the utility model can maximize the volume of the chip groove by designing the cutting tool as a structure of a cutting edge and a chip groove, so that the waste chips generated by cutting can have a larger space to be accommodated and discharged, and the chip removal effect of the tool can be improved while meeting the tool stiffness requirements.

At least two shovel backs 5 are provided on the tool head 2 on the side of the cutting circumferential tooth 4 away from the chip groove 3. Multiple shovel backs 5 cover the tool head between the two sides of the chip groove 3 for avoiding the honeycomb aluminum plate to prevent the tool head 2 from touching the honeycomb aluminum plate for the second time. At the same time, it can also play a certain chip removal role. The volume of the chip groove 3 is 1 / 4 to 1 / 2 of the volume of the tool head 2. While ensuring the structural strength of the tool, the volume of the chip groove 3 is increased as much as possible. The inner wall cross-section of the chip groove 3 is an arc surface, which can be milled at one time, and the processing is more convenient.

[0032] Preferably, a first end tooth back angle 7 is provided on the rear side of the cutting end tooth 6, and a second end tooth back angle 8 is also provided on the cutter head 2 on the rear side of the first end tooth back angle 7. The structure of the two end tooth back angles makes it more convenient to cut the cutting end tooth 6 and is more conducive to the discharge of waste chips. Furthermore, the first end tooth back angle 7 and the second end tooth back angle 8 are the same, and are both greater than 0° and less than or equal to 50°. The angles of the two end tooth back angles are reasonably optimized, which facilitates processing while ensuring the structural strength of the tool.
