                彎頭廠(chǎng)舉例說(shuō)明:以齊心巨細頭為例,設年夜頭半徑為R1,小頭半徑為R2,高為H,碳鋼彎頭這三個(gè)數據在鈑金圖紙上是已知的。為便利盤(pán)算,設年夜頭圓弧的半徑為RD,睜開(kāi)的角度為α

                彎頭廠(chǎng)舉例說(shuō)明:以齊心巨細頭為例,設年夜頭半徑為R1,小頭半徑為R2,高為H,碳鋼彎頭這三個(gè)數據在鈑金圖紙上是已知的。為便利盤(pán)算,設年夜頭圓弧的半徑為RD,睜開(kāi)的角度為α,平焊法蘭小頭圓弧的半徑為RX,(R1—R2)=(ΔR),L為巨細頭側面投影的長(cháng)度。
                有(RD—RX)=L=[(H)^2+(ΔR)^2]^(0.5)
                RD=(R1×L)÷(ΔR),
                RX=(R2×L)÷(ΔR),
                睜開(kāi)的角度為α=[180×(ΔR)]÷(L×π), 單元是度。
                異心巨細頭要根據鈑金圖紙睜開(kāi)。
