大型截止阀阀体剪-挤成形技术实验研究

SYUDY ON THE SHEAR-EXTRUSION TECHNOLOGY OF LARGE-SCALE SHUTOFF VALVE BODY

基于杯 杆复合挤提出了剪 挤成形技术 ,认为剪 挤成形工艺最大的力学特点是节能省力。并利用该工艺节能省力的特点 ,在 10 0 0 0kN离合器式螺旋压力机上成功地锻造成形了材料为钢 2 0及 12Cr1MoV公称尺寸为DN10

Based on cup-bar extrusion, this paper presented shear-extrusion technology with advantage of laborsaving. The character of laborsaving in shear-extrusion was utilized to shape up DN100 shutoff valve body of steel 20 and 12Cr1MoV on 10000KN clutch-screw press.
