天圓地方不鏽鋼鈑金放樣下料方法

1.先實(shí)際尺寸畫出側(cè)視圖和俯視圖,然後把俯視圖上的1/4圓弧等分成3份。再把分出的各點(diǎn)(1234)用直線(abcd)F點(diǎn)相連。(步驟相對應(yīng)1-1圖與1-2圖)

2.再畫一條直線,取一點(diǎn)I,量取高度尺寸以I點(diǎn)為起點(diǎn)在直線上標(biāo)注一點(diǎn)J。然後過I點(diǎn)畫一條與其垂直相交線,量取直線a的長度以I點(diǎn)為起點(diǎn)在線上標(biāo)注一點(diǎn)K,再量取直線b長度以I點(diǎn)為起點(diǎn)在直線標(biāo)注一點(diǎn)L 。用直線eK J兩點(diǎn)相連,再用直線fL J兩點(diǎn)相連 。(步驟相對應(yīng)1-3圖)

3.① 以方頭一邊的長度畫出一條P Q直線,找出P Q直線中心點(diǎn)O畫一條與其垂直相交線。

② 以點(diǎn)Q為圓心,直線e為半徑(以下稱Qe圓弧)在垂直相交線上畫圓弧相交於點(diǎn)7,用直線把7 Q兩點(diǎn)相連。

③ 以點(diǎn)Q為圓心,直線f為半徑畫圓弧(以下稱Qf圓弧)。再量取俯視圖中的點(diǎn)1與點(diǎn)2之間的弦長(以下稱12弦長)為半徑,點(diǎn)7為圓心畫圓弧相交於點(diǎn)6,用直線把6 Q兩點(diǎn)相連。

④ 以點(diǎn)6為圓心,12弦長為半徑畫圓弧與Qf圓弧相交於點(diǎn)5,用直線把5 Q兩點(diǎn)相連。

⑤ 以點(diǎn)5為圓心,12弦長為半徑畫圓弧與Qe圓弧相交於點(diǎn)4,用直線把4 Q兩點(diǎn)相連。

⑥ 以點(diǎn)Q為圓心,線段PQ為半徑畫圓弧,再以點(diǎn)4為圓心,線段7Q為半徑畫圓弧相交於點(diǎn)S,用直線把Q S兩點(diǎn)相連。再用直線把點(diǎn)4與點(diǎn)S相連。

⑦ 以點(diǎn)S為圓心,線段Q4為半徑畫圓弧(以下稱S4圓弧),再以點(diǎn)S為圓心,直線f半徑,畫圓弧(以下稱Sf圓弧)。

⑧ 以點(diǎn)4為圓心,12弦長為半徑畫圓弧與Sf圓弧相交於點(diǎn)3,用直線把3 S兩點(diǎn)相連。

⑨ 以點(diǎn)3為圓心,12弦長為半徑畫圓弧與Sf圓弧相交於點(diǎn)2,用直線把2 S兩點(diǎn)相連。

⑩ 以點(diǎn)2為圓心,12弦長為半徑畫圓弧與S4圓弧相交於點(diǎn)1,用直線把1 S兩點(diǎn)相連。

4.以點(diǎn)4為圓心,點(diǎn)O4之間的距離為半徑畫圓弧(以下稱O4圓弧),再以點(diǎn)S為圓心,O Q兩點(diǎn)的長度為半徑(即是1/2邊長)畫圓弧與O4圓弧相交於點(diǎn)T,用直線把S T兩點(diǎn)相連,再用直線把點(diǎn)1與點(diǎn)T相連。(步驟相對應(yīng)1-4

5.用線段把1 2 3 4 5 6 7依次連接,即得1/2展開圖。(步驟相對應(yīng)1-4
