Patent number: 11311970Abstract: A shielding gas nozzle for metal forming includes a wire feed line being a path to feed a wire at an inclination angle ?, a first gas ejection hole to jet a shielding gas at an angle equal to or less than the inclination angle ?, and a second gas ejection hole to jet the shielding gas in a direction different from that of the first gas ejection hole. The first gas ejection hole jets the shielding gas toward an intersection along a direction in which the absolute value of the angle to the wire feed direction is less than 90 degrees, and the second gas ejection hole jets the shielding gas toward the intersection along a direction in which the absolute value of the angle to the wire feed direction when viewed in the direction perpendicular to the base material surface is greater than 90 degrees.Type: GrantFiled: April 16, 2019Date of Patent: April 26, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Yoshikazu Nakano, Hidetaka Katogi, Akiyoshi Sawai

Publication number: 20190377326Abstract: An additive manufacturing apparatus includes: an irradiation unit that irradiates a feeding position with a laser beam that melts a build material; a numerical control device that is a control unit that performs control for building a deposit by stacking beads on a substrate; and an arithmetic device that is an arithmetic unit that executes an arithmetic process of computing parameters for the control unit to perform the control unit. The beads, which are two beads stacked on each other, are a first bead and a second bead stacked on the first bead. The first bead is formed earlier than the second bead. The feeding position is a first position in formation of the first bead. The feeding position is a second position in formation of the second bead. On a basis of a width of the first bead and a diameter of the laser beam, the arithmetic unit calculates an interval between the first position and the second position in a set direction that is a direction of the width of the first bead.Type: ApplicationFiled: March 2, 2018Publication date: December 12, 2019Applicant: Mitsubishi Electric CorporationInventors: Hidetaka KATOGI, Yoshikazu NAKANO
