【摘要】：通過(guò)對(duì)半球形殼體類零件旋壓成形過(guò)程進(jìn)行分析,提出了半球形殼體兩模法旋壓工藝路線,通過(guò)制作模具,最終旋壓獲得了滿足尺寸要求的半球形殼體。對(duì)鋼、鈦、紫銅、純銀等材料半球形殼體進(jìn)行旋壓驗(yàn)證并獲得成功。結(jié)果表明:兩模法用于半球形、偏心半球、橢球形等薄壁殼體類零件的旋壓,能減少殼體口部金屬旋壓變形次數(shù),減小加工硬化,有利于提高殼體最終尺寸精度。采用預(yù)制沖壓板坯結(jié)合尾頂?shù)暮侠硎褂?當(dāng)芯模轉(zhuǎn)速為150~250 r·min-1,旋輪進(jìn)給比為1~3 mm·r-1時(shí)能獲得較好的旋壓件表面質(zhì)量。
[Abstract]:By analyzing the spinning forming process of hemispherical shell parts, the two-die spinning process of hemispherical shell is put forward. By making die, the hemispherical shell can be obtained by spinning finally. The hemispherical shell of steel, titanium, copper and pure silver was tested successfully. The results show that the twin-mode method can reduce the number of metal spinning deformation at the shell mouth, reduce the work hardening, and improve the precision of the shell's final dimension by applying the twisting method to the hemispherical, eccentric hemisphere, ellipsoid and other thin-walled shell parts. When the core die speed is 150 ~ 250r / min ~ (-1) and the feed ratio of the rotary wheel is 1 ~ 3 mm / r ~ (-1), the surface quality of the spinning part can be obtained by using the precast stamping slab and the tail-top reasonably.
