style="text-indent:25px">球形封頭的放樣方法：定義如下：D0=1000，徐州罐式運(yùn)輸車(chē)封頭廠家，δm=2，h=0（為了便于演示，h定義為零），H=250步驟如下：1、畫(huà)出構(gòu)件的主視圖及其構(gòu)件的斷面圖。2、將斷面圖分成若干等份。這里取24份。3、將主視圖一根素線(xiàn)分成若干等份。這里取6份。由等分點(diǎn)向斷面圖引若干垂線(xiàn)，交斷面圖水平線(xiàn)段若干點(diǎn)。并以斷面圖圓心為圓心，以圓心到垂足的距離為半徑作若干圓。4、以所選的素線(xiàn)的長(zhǎng)度畫(huà)一條豎直的線(xiàn)段。并分成和素線(xiàn)相等的份數(shù)。素線(xiàn)長(zhǎng)為605.501這里是6份。5、在所作的若干圓上截取相應(yīng)的同心圓弧的長(zhǎng)度，為了下料方便，把弧長(zhǎng)轉(zhuǎn)化成線(xiàn)段的長(zhǎng)度，徐州罐式運(yùn)輸車(chē)封頭廠家，按順序分別添加到素線(xiàn)的等分點(diǎn)上。6、對(duì)用弧長(zhǎng)的和用線(xiàn)段的進(jìn)行比較，如圖3得之，用弧長(zhǎng)的稍比用線(xiàn)段的長(zhǎng)一些。如圖4較大差值*為0.2mm，徐州罐式運(yùn)輸車(chē)封頭廠家。因此為了下料方便我們可以取，用線(xiàn)段表示的方法畫(huà)近似瓜瓣。7、在這里，大家都可以理解，素線(xiàn)的等分點(diǎn)越多，那么放樣得到的就越接近實(shí)際尺寸。無(wú)限等分后的結(jié)果就是實(shí)際瓜瓣。但是我們做不到，只能根據(jù)實(shí)際情況，按照客戶(hù)或其他原因，選取n的等分點(diǎn)進(jìn)行放樣。封頭的安裝步驟要遵守規(guī)范，避免不能正常使用。徐州罐式運(yùn)輸車(chē)封頭廠家</p><div
