  • Publication number: 20220275779
    Abstract: An object of the present invention is to provide a working method of an orifice, which has excellent working accuracy and high productivity in order to work an inclination portion (tapered portion) on the entire circumference of an inner wall of an orifice. Therefore, a working method of an orifice includes a first step of forming an orifice hole 54d in an orifice forming member, a second step of pressing a downstream end surface of the orifice forming member in which the orifice hole 54d opens, in a direction toward an upstream side of the orifice hole 54d by a punch 46 having a cutting blade portion 46a larger than a cross section of the orifice hole 54d. The second step causes a material of the orifice forming member to flow from an entire circumference at the downstream end portion of the orifice hole 54d to an inside of the orifice hole 54d to form a cross-sectional area reduction portion 54s in which a cross-sectional area of the orifice hole 54d is reduced from an upstream side to a downstream side.
