锻挤工艺是用模锻使工件予成形后,在压床上挤压成形的一种新的复合工艺。我厂用这种方法制作铁牛45差速器半轴齿轮,提高了毛坯精度,节约了钢材,提高工效4倍,班产1200件。我厂用5吨锻锤锻打半轴齿轮齿冠一端,柄端用500吨压床扩孔、反挤和冲孔,一火成形,工序流程见图1。 Forging extrusion process is forging the workpiece to the shape, the press on the extrusion forming a new composite process. I plant this method of making 45 steel differential gear semi-axle gear to improve the precision of the blank, saving steel, improve work efficiency 4 times, production of 1200 classes. I plant with 5 tons of forged hammer forged half shaft gear crown end, the handle end with 500 tons of press reaming, anti-extrusion and punching, a fire forming, process flow shown in Figure 1.
