Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a cutting milling cutter for anti-peeling composite boards. Background Art

[0002] In the processing and manufacturing industries, cutting tools are indispensable key components. Milling cutters are mainly used for efficient cutting of hard materials and can maintain good performance under extreme working conditions.

[0003] Currently, the composite boards on the market adopt a multi-layer structure design. The hardness of the upper and lower layers of materials is relatively large, while the hardness of the middle layer is relatively small. For example, the structure of "melamine + synthetic wood + melamine" is adopted to achieve the purpose of balancing strength and toughness. However, some problems have emerged in actual use: the composite board is prone to peeling; during the cutting process, due to the large hardness difference between the upper and lower layers and the middle layer, when subjected to a large cutting force, the composite board is prone to peeling, resulting in shortened tool life and reduced machining quality; furthermore, the cutting resistance is large: the existing milling cutters adopt a design of a whole blade, that is, the entire cutting edge is a continuous whole. Such a design increases the contact area with the workpiece, thereby increasing the cutting resistance, especially when cutting hard materials at high speed. The heat generated by the entire cutting edge will also affect the accuracy of the milling cutter and shorten its life.

[0004] Now, in order to solve the above technical problems, the utility model designs a cutting milling cutter for anti-peeling composite boards. Summary of the Utility Model

[0005] The utility model provides a cutting milling cutter for anti-peeling composite boards, aiming to solve the problems that during the processing of composite boards, the composite board peels off, and the existing entire cutting edge generates a large cutting resistance, resulting in shortened tool life and reduced accuracy of the milling cutter. The technical solution is as follows:

[0006] A cutting milling cutter for anti-peeling composite boards: includes a tool body, a first cutting tool and a second cutting tool. The first cutting tool and the second cutting tool are obliquely arranged on the tool body. The first cutting tool and the second cutting tool are both arranged in several rows parallel to each other on the tool body. The first cutting tool and the second cutting tool both include a tool holder, a blade and a chip removal groove. The blade is detachably connected to the tool holder. A chip removal groove is opened on the tool body. The chip removal groove is located on one side of the blade. The first cutting tool and the second cutting tool are arranged closely in sequence from the center to the edge on the tool body.

[0007] Based on the above technical solution, one end of the chip removal groove near the edge of the tool body is open.

[0008] Preferably, the blade is made of diamond material.

[0009] Preferably, the chip removal groove is an arc-shaped groove.

[0010] Beneficial effects

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: on the one hand, the design of multiple segmented cutting tools reduces the contact length between a single cutting edge and the workpiece, thereby reducing the cutting resistance and increasing the tool life. On the other hand, the inclined downward pressure of the first cutting tool and the upward pressure of the second cutting tool on the composite board help to fix the board, reduce the risk of peeling, and improve the processing quality. On yet another hand, the design of the overlapping cutting areas of the cutting tools adapts to the boards with greater edge hardness through multiple machining of the overlapping areas, improving the processing quality and efficiency.

[0018] The following further illustrates the present utility model in conjunction with the drawings and examples:

[0019] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] As Figure 5 shown, the composite board is bonded by an upper board 71, an intermediate board 72, and a lower board 73. The two layers of materials of the upper board 71 and the lower board 73 have a greater hardness, and the hardness of the intermediate board 72 is smaller.

[0023] As Figure 1 and Figure 2 shown, a peeling-resistant composite board cutting milling cutter is characterized in that it includes a cutter body 1, a first cutter 2, and a second cutter 3. The first cutter 2 and the second cutter 3 are obliquely arranged on the cutter body 1. The first cutter 2 and the second cutter 3 are each arranged in several rows in parallel on the cutter body 1, and the first cutter 2 and the second cutter 3 are arranged in sequence from the center to the edge on the cutter body 1 in a close manner.

[0024] As Figure 3 shown, the arrangement trajectory a of the first cutter 2 is arranged obliquely downward, and the arrangement trajectory b of the second cutter 3 is arranged obliquely upward. When the milling cutter works, the cutter body 1 rotates counterclockwise, rotates from left to right as Figure 2 shown. The first cutter 2 generates a downward pressure on the composite board, and the second cutter 3 generates an upward pressure on the composite board. The upper board 71 and the lower board 73 apply pressure to the intermediate board 72, thereby reducing the risk of peeling.

[0025] The design of multiple cutters in a segmented manner can reduce the contact area between each cutting edge and the workpiece. Through sectional cutting, the cutting force borne by a single cutting edge is reduced, and further the total resistance during the cutting process is reduced. By reducing the contact length of a single cutting edge, the pressure and wear on each cutting edge can be alleviated, and the overall service life of the cutter is prolonged.

[0026] The first cutting tool 2 and the second cutting tool 3 are arranged closely in sequence from the center to the edge on the tool body 1. The cutting tools are arranged closely in sequence from the center to the edge, and the cutting areas have a certain overlap. The overlap area is larger at the upper and lower parts and smaller in the middle.

[0027] The upper plate 71 and the lower plate 73 are harder and require more cutting times. Therefore, the cutting overlap area at the edge is larger to adapt to the plate with harder upper and lower parts and softer middle part.

[0028] Such as Figure 4 As shown, both the first cutting tool 2 and the second cutting tool 3 include a tool holder 5, a cutting blade 4 and a chip groove 6. The cutting blade 4 is detachably connected to the tool holder 5. The chip groove 6 is opened on the tool body 1, and the chip groove 6 is located on one side of the cutting blade 4.

[0029] The chip groove 6 helps to guide the chips to be discharged smoothly, avoiding the additional cutting resistance and tool damage caused by chip clogging.

[0030] One end of the chip groove 6 near the edge of the tool body 1 is open. The open end can be used as the outlet of the chips, which helps the chips to be discharged smoothly, avoids chip clogging the tool, and reduces the cutting resistance. The faster the chips are removed, the more the continuity and efficiency of the cutting process can be ensured. The chip groove 6 is an arc-shaped groove for better chip discharge.

[0031] The cutting blade 4 is made of diamond material.

[0032] The above has illustrated the present utility model by way of example, but the present utility model is not limited to the above specific embodiments. Any modification or variation based on the present utility model falls within the scope of protection required by the present utility model.
