Problems solved by technology

[0005] However, especially under high-feed cutting conditions where the feed rate per tooth is about 0.8 to 1.0mm / tooth, larger iron filings will be formed. The thicker the iron filings, the greater the cutting resistance the tool must bear. The larger the cutting resistance is, the main cutting resistance acts on the main cutting edge, and a large amount of cutting heat is generated. There is a high probability that the cutting edge of the blade will experience abnormal wear, and even chipping, which will affect the service life of the blade. In high-efficiency machining with high quality requirements, it is particularly important to reduce the cutting resistance impact of the main cutting edge, especially the wiper edge. Generally, in high-speed feed processing, the cutting allowance of the blade is large, and the cutting resistance and cutting heat It will completely act around the main cutting edge, resulting in faster damage to the main cutting edge, and the surface quality of the part cannot be guaranteed

Embodiment 1

[0041] like figure 1 Shown is a high-efficiency cutting blade described in this embodiment, including a blade body 100 surrounded by an upper bottom surface 1, a lower bottom surface 2, and a side surface 3 connecting the upper bottom surface 1 and the lower bottom surface 2, the blade The cutting unit 4 is distributed on the main body 100, and the cutting unit 4 includes at least one main cutting edge 5. Under the cutting condition of a certain amount of feed, the main cutting edge 5 makes relative movement between the blade body 100 and the parts, so that the blade body 100 cuts into the inside of the part, forms curled chips on the rake face, and removes excess material; the main cutting edge 5 is composed of a wiper edge 501, a first cutting edge 502 and a second cutting edge 503, and the wiper edge 501 is in a straight line state, the wiper edge 501, the first cutting edge 502 and the second cutting edge 503 protrude toward the outside of the insert body 100 and form a sp...

Embodiment 2

[0061] like Figure 12 As shown, the difference between this embodiment and Embodiment 1 lies in the assembly method of the blade body 100. Specifically, the blade body 100 can be rotated counterclockwise around the rotation center 28 for cutting processing, which widens the blade body 100. range of use, so that all parts of the blade body 100 can play a role. The blade main body 100 is also installed on the cutter body at a negative axial angle for cutting processing, and the cutting relief angle is reserved. The rotation plane of the first secondary cutting edge of the blade main body 100 is kept coincident with the cutting plane 26, so as to The smoothing effect on the surface of the part, the second auxiliary cutting edge undertakes the main work of removing the material of the part, and at the same time, the auxiliary cutting edge and its auxiliary space-avoiding edge will also participate in the actual cutting task in the case of large depth of cut. At the same time, the...

Abstract

The invention discloses an efficient cutting blade which comprises a blade body defined by an upper bottom face, a lower bottom face and a side surface connected with the upper bottom face and the lower bottom face, cutting units are distributed on the blade body, each cutting unit comprises at least one main cutting edge, each main cutting edge is composed of a sleeking edge, a first cutting edge and a second cutting edge, wherein the sleeking edge is in a linear state, and the sleeking edge and the first cutting edge are in smooth connection through a first bridging curve, and the first cutting edge and the second cutting edge are in smooth connection through a first bridging curve. According to the efficient cutting blade, the cutting resistance can be decomposed, the impact of the cutting resistance on the sleeking edges is reduced, the damage probability of the sleeking edges is reduced, and a high-quality surface is continuously and stably machined while efficient cutting machining is guaranteed.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a high-efficiency cutting blade. Background technique [0002] In metal cutting, milling is the most common processing method. Usually, the required processing parts are fixed on the machine tool table, and the high-speed rotating milling tool is used to move the tool on the surface of the part at a certain feed rate, and the desired machining results are obtained. The shape and characteristics of the required parts, among which, the feed rate of the tool determines the cutting efficiency of the tool. If the feed rate per tooth (or per revolution) of the tool is greater, the volume of iron filings removed will be larger, which means that the total mass of iron filings processed per unit time will be greater. It can be understood that the tool’s The higher the metal removal rate, the higher the cutting efficiency of the insert. In order to improve the metal removal rate an...
