Claims

[Claims for Utility Model Registration] (1) A pair of upper and lower rotating shafts 11, 1 that are rotationally driven.
2 are arranged in parallel, and each rotating shaft 11, 12 is provided with a parting tool 15, 16 that protrudes outward in the radial direction, and these cutting tools 15, 16 approach each other, In the case where the tip of the running wire material 5 is cut as the tip crop material 5a, when the tip of the running wire material 5 is cut, the upper parting tool 15 is moved forward in the rotational direction than the lower cutting tool 16. It is made to take the lead, and the lower parting tool 16
A flying shear device characterized in that the cutting edge of the upper parting bit 15 is sharper than the cutting edge of the upper parting bit 15. (2) The upper parting bit 15 is placed on the tip side rake face 3
1 and a base-side rake face 32, and the rake angle 34 of the base-side rake face 32 is larger than the rake angle 33 of the tip-side rake face 31. Flying shear device as described in section.
