Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0012] Such as figure 1 As shown, the chip-breaking grooving knife includes a cutter body 3 and a cutter head 5 arranged at the end of the cutter body. The cutter head 5 is provided with a cutting edge 4; 1. The winding blocking block 1 is inlaid on the opposite end of the cutting edge 4 .

[0013] The blocking block 1 is L-shaped, and an arc transition is provided at one end close to the cutting edge 4. The arc size of the blocking block 1 is R2-R3, and the position of the blocking block 1 is at the cutting edge. The upper end is 3-5mm in the direction of the cutter body. The winding blocking block 1 is made of a metal material whose hardness is greater than that of aluminum alloy. The winding blocking block 1 is provided with a screw hole 2 .

[0014] Such as figure 2 As shown, the cutter body 3 is provided with fastening holes 6 corresponding to the scre...

Abstract

The invention relates to a chip-breakable groove cutter and belongs to the technical field of cutting tools. The chip-breakable groove cutter comprises a cutter head and a stop block. The cutter head is arranged on the end portion of a cutter body, and a cutting blade is reserved on the cutter head; the stop block is embedded at the upper end of the cutting head, is embedded at the end opposite to the cutting blade and is L-shaped; a transitional circular arc is arranged at the end, close to the cutting blade, of the stop block, the size of the circular arc is R2-R3, a screw hole is reserved on the stop block and a fastening hole corresponding to the screw hole on the stop block is reserved on the cutter body. The chip-breakable groove cutter is simple, ingenious and reasonable in structure and can effectively prevent aluminum rods produced in processing from twisting on the cutter body, so that bright, clean and attractive appearance of the surface of the processed aluminum alloy can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cutting tools, in particular to a grooving knife. Background technique [0002] In the prior art, the grooving knife for processing the inner hole groove of aluminum alloy material has no setting for chip breaking. The direct consequence of the above situation is that the aluminum strip produced during the processing of aluminum alloy material is easy to wrap around the cutter body, causing scratches. Damage the processed aluminum alloy material, resulting in a high scrap rate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a chip-breaking grooving knife with a simple, ingenious and reasonable structure, which can effectively avoid the aluminum strip winding around the knife body to the problem. [0004] According to the technical solution provided by the present invention: a grooving cutter capable of breaking chips...
