一般圆锥筒形零件，可在普通卷板机上采用阻力成形法［1］或辅助套筒成形法[2]直接卷制。当圆锥筒形零件的锥度和壁厚尺寸较大时，普通卷板机则无能为力了。此时，可采用图二所示的锻模直接成形。将圆环状毛坯放入固定的通用支座上的圆锥孔下模中，然后用锥形冲头压人毛坯。冲 General cone-shaped cylindrical parts, can be used in ordinary rolling machine resistance forming method [1] or auxiliary sleeve forming method [2] direct rolling. When the taper cone-shaped parts and wall thickness larger size, ordinary coiler is powerless. In this case, the forging die as shown in Fig. 2 can be directly formed. Place the ring blank into the conical hole lower die on the fixed universal support and press the blank with a conical punch. Rush
