본 발명은, 차축의 베어링을 수용하는 축 상자에 지지된 상태에서 차량의 길이방향으로 연장됨으로써 크로스 빔을 탄성적으로 지지하는 판 스프링을 제조하기 위한 철도 차량 대차용 판 스프링의 제조 방법으로서, 주면의 법선 방향에서 볼 때, 일 방향으로 배열된 연속 섬유의 층을 가지는 섬유 강화 수지의 메인 플레이트를 성형하는 성형공정, 상기 메인 플레이트를 일 방향을 따라 절단하기 위하여 평행한 복수의 절단선의 위치를 결정하는 절단위치결정공정 및 상기 복수의 절단선을 따라 상기 메인 플레이트를 절단함으로써 섬유 강화 수지로 이루어지는 복수의 판 스프링을 추출하는 절단공정을 포함하는 판 스프링의 제조 방법에 관한 것이다.

    A method of producing plate springs for a railcar bogie, the plate springs each extending in a car longitudinal direction and elastically supporting a cross beam while being supported by an axle box in the railcar bogie, the axle box accommodating a bearing for an axle, the method includes: a molding step of molding a mother plate made of fiber-reinforced resin, the mother plate including a layer made of continuous fibers oriented in a first direction when viewed from a normal direction of a main surface of the mother plate; a cut position determining step of determining positions of a plurality of parallel cut lines for cutting the mother plate along the first direction; and a cutting step of cutting the mother plate along the plurality of cut lines to take out the plate springs made of the fiber-reinforced resin.
