Specific embodiment
Technical solution of the present invention will be clearly and completely described below.
A kind of side set molding bloom angle cutting tool, as shown in Figure 1, including knife handle, cutter head；
The knife handle 1 and cutter head are integrally formed, and the cutter head includes the first blade, the second blade, third blade, the 4th knife
Sword, first blade, the second blade, third blade, the 4th blade are successively opened in the end of the knife handle clockwise；
First blade, the second blade, third blade, the inclination of the 4th edegewise, and compatible front-end face 8, such as Fig. 1 institute
Show, front end face 8 is a flat surface, and the first blade and the central spindle of third blade, the second blade and the 4th blade about the knife handle
Before the point diameter D2 of endpoint central symmetry, first blade and third blade is greater than second blade and the 4th blade
Diameter D3 is held, and the difference of point diameter D2 and point diameter D3 is not less than 0.6 ± 0.006；First blade and third knife
The angle α of sword is less than the angle β of the second blade and the 4th blade, and the difference of angle α and angle β are not less than 25 °.Namely
It says, in four blades of the invention, end face diameter and the angle difference of two pairs of blades form two pairs of staggered side set structures, benefit
Can be using one knife with side set structure, a process processes the two adjacent fillet surfaces of liquid metal.
Further, the angle α of first blade and third blade be 46 ° ± 0.3 °, the second blade and the 4th blade
Angle β is 72 ° ± 0.3 °.
