Abstract

본 발명은 로터 폴의 샤프트 홀에 샤프트를 압입시키는 공정에서 냉간단조 공정에 의해 샤프트의 경도보다 높아진 샤프트 홀의 경도를 낮추기 위해 행하는 열처리 공정을 제거함으로써 제작공정수와 제작비용을 줄일 수 있는 교류발전기의 로터 제조방법을 제공하는데 있고, 소재(100)를 성형품의 중량에 맞게 소정의 크기로 절단하는 제1공정과, 절단된 소재(100)를 750-850℃로 가열하는 제2공정과, 가열된 소재를 금형내에 넣고 가압하여 1차 성형품(101)을 성형함과 동시에 샤프트(104)가 압입되어지는 샤프트 홀(102)을 성형하는 제3공정과, 상기 1차 성형품에 냉간단조를 위한 윤활 처리하는 제4 공정과, 윤활 처리된 1차 성형품을 금형내에 넣고 상온에서 냉간단조를 행하여 로터 폴(103)을 완성하는 제5공정과, 상기 완성된 로터 폴 2개를 서로 맞대어 겹친 후 샤프트 홀에 샤프트를 압입시키는 제6공정으로 이루어진다.The present invention is to remove the heat treatment process to reduce the hardness of the shaft hole higher than the hardness of the shaft by the cold forging process in the process of pressing the shaft into the shaft hole of the rotor pole of the alternator that can reduce the number of manufacturing process and manufacturing cost In providing a method for manufacturing a rotor, the first step of cutting the material 100 to a predetermined size according to the weight of the molded article, the second process of heating the cut material 100 to 750-850 ℃, and A third step of forming the shaft hole 102 into which the shaft 104 is pressed while forming a primary molded product 101 by pressing a raw material into a mold; and lubricating treatment for cold forging to the primary molded product. A fourth step of placing the lubricated primary molded product in a mold and performing cold forging at room temperature to complete the rotor pole 103, and the two completed rotor poles overlapped with each other. It comprises a sixth step of press-fitting the shaft into the shaft hole.
