Embodiment Construction

[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0014] like Figure 1~2 As shown, the present invention mainly includes a cutter body 1, a cutter head connecting body 2 is arranged at the end of the cutter body 1, a cutter head 3 is arranged at the end of the cutter head connecting body 2, and the cutter head 3 and the cutter head connecting body 2 are perpendicular to each other.

[0015] The end of the cutter head 3 is provided with a cutting edge 4 , and the cutting edge 4 includes one or more sawtooth-shaped protrusions 5 , and V-shaped portions 6 are arranged on both sides of the protrusions 5 .

[0016] The front part of the traditional cutting edge 4 is flat and straight, and the width of aluminum chips formed by cutting is relatively large, and it is easy to form aluminum strips with large width and size to be wound on the cutter body, and flanging burrs are easily generated on the inner sid...

Abstract

The invention relates to a groove cutter, in particular to a groove cutter capable of preventing chip curling and generation of aluminum rings, and belongs to the technical field of cutting tools. The groove cutter comprises a cutter body. A cutter bit connector is arranged at the end of the cutter body. A cutter bit is arranged at the end of the cutter bit connector, and a cutting edge is arranged at the front end of the cutter bit and comprises a straight part and convex parts arranged on the two sides of the straight part. The groove cutter is simple, compact and reasonable in structure, the situation that flanging burrs are generated in the machining process can be effectively avoided, and then the yield is increased.

Description

technical field [0001] The invention relates to a grooving knife, in particular to a grooving knife capable of automatically breaking chips and removing flanging burrs, and belongs to the technical field of cutting tools. Background technique [0002] In the prior art, the grooving knife for machining the inner hole of the aluminum alloy material does not have the function of chip breaking, and the edges of the machined groove are prone to flanging burrs. The direct consequence of the above situation is that when processing the aluminum alloy material The resulting ring-shaped aluminum strips are easy to wrap around the cutter body and scratch the processed aluminum alloy material, especially when processing the supercharger casing, the circled aluminum strips after processing are easy to stay in the supercharger flow channel , It is difficult to clean it out, resulting in a high scrap rate, and it is difficult to remove the flanging burrs on both sides of the inner side of ...
