Abstract
An apparatus for manufacturing a blade is provided. The apparatus for manufacturing a blade includes: an arm module including a pressing unit pivoting around a first shaft; a molding module including a molding die pressed by the pressing unit and molding bulk metallic glass (BMG) to a blade; and a drawing module pulling an end portion of the BMG exposed to the outside of the molding die to form an edge of the blade, wherein the drawing module includes a pair of drawing tools pulling one end portion of the BMG in two directions.
Claims11
An apparatus for manufacturing a blade, the apparatus comprising:
- an arm module including a pressing unit pivoting around a first shaft;
- a molding module including a molding die, wherein the molding die is pressed by the pressing unit and a bulk metallic glass (BMG) is pressed to be molded to a blade in the molding die;
- and
- a drawing module pulling an end portion of the BMG exposed to the outside of the molding die to form an edge of the blade,
- wherein the drawing module includes a pair of drawing tools pulling one end portion of the BMG in two directions so as to generate a necking due to a plastic deformation of the BMG, and
- wherein the pair of drawing tools pull the one end portion of the BMG in the two directions positioned to be coplanar with a direction in which the blade extends and forming a predetermined angle with respect to the direction in which the blade extends.
