- a shaving tool that gradually decreases toward the surface
- significant work efficiency is achieved. This is because when such a shaving tool is used, not only the smoothness of the surface of the steel wire can be secured, but the surface of the steel wire can be obtained only by passing the steel wire through the shaving tool once at a high feed rate. This is because it is possible to secure a predetermined amount of scraping from the layer.
- FIG. 1 is a schematic diagram for explaining a state in which a steel wire is shaved with a shaving die provided in the shaving tool of the present invention.
- 1 is a steel wire rod (hereinafter referred to as “steel wire rod”)
- 2 is a shaving die provided in a shaving tool.
- a predetermined amount of the surface layer of the steel wire 1 can be scraped off while generating chips from the surface layer of the steel wire 1. become.
- FIG. 2 is a schematic diagram for explaining the configuration of each part of the blade edge 2a of the shaving die 2 shown in FIG.
- ⁇ S is a rake angle
- ⁇ N is a clearance angle.
- the definitions of the positive (plus) direction and the negative (minus) direction of each of the rake angle ⁇ S and the relief angle ⁇ N are as shown in FIG. D is the inner diameter of the cutting edge 2a of the shaving die 2.
- the present invention secures a predetermined amount of scraping from the surface layer of the steel wire rod 1 and also ensures the smoothness of the surface of the steel wire rod 1 and suppresses chipping and wear of the cutting edge 2a and has a long life.
- a shaving tool with 2 is provided.
- any of cemented carbide, high-speed tool steel and ceramics is suitable as the material of the cutting edge 2a of the shaving die 2.
- the surface roughness (arithmetic mean roughness) Ra after scraping off the surface layer of the steel wire 1 with respect to the surface layer of the steel wire 1 having an outer diameter of ⁇ 8 mm and a Vickers hardness Hv 230 is an allowable value (about 0 .4 ⁇ m) was examined.

- the cutting component force during shaving that is, the force directed in the direction perpendicular to the feed direction of the steel wire 1 (normal direction)
- the shaving die. 2 acts toward the axial direction. Since this acts as a kind of aligning action on the steel wire 1, the deflection of the steel wire 1 during shaving is suppressed, and the unevenness of the steel wire 1 after shaving is reduced. It is thought that the suppression effect was improved.
- the small unevenness is also advantageous from the viewpoint of ensuring the smoothness of the surface of the steel wire 1 after shaving. Further, as described above, since the amount of scraping that satisfies both the above conditions is in a wide range, the work efficiency for achieving a predetermined large amount of scraping is improved.
