Description

단조품의 제조 방법Manufacturing method of forging

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1도는 본 발명의 일실시에에 있어서의 크랭크축 단조품의 제조공정을 표시한 공정도,1 is a process chart showing the manufacturing process of the crankshaft forging in one embodiment of the present invention,

제 2도는 제품으로서의 크랭크축의 요부단면도,2 is a main cross-sectional view of the crankshaft as a product,

제 3도는 회전밸런스측정기의 개략정면도.3 is a schematic front view of a rotation balance measuring instrument.

Claims (1)

회전부재를 단조공정에 의해서 소정형상으로 성형해서 단조품을 얻은후, 상기 단조품의 전단회전밸런스 측정을 행하고, 이단조품의 밸런스 상태가 밸런스 수정가능 범위내의 양품인지 불량품인지 판정하고, 다음에 양품은 각종가공을 실시한후, 최정적 회전밸런스 측정에 의거하여 밸런스 수정가공을 실시하는 한편, 불량품은 사이징 공정에 보내어 교정하고, 재차 상기 전단회전밸런스 측정을 행하는 것을 특징으로 하는 단조품의 제조방법.After the rotating member is molded into a predetermined shape by a forging process to obtain a forged product, the shear rotation balance measurement of the forged product is carried out. After the processing, the balance correction processing is performed based on the most accurate rotational balance measurement, while the defective product is sent to the sizing step to correct, and the shear rotational balance measurement is performed again. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
