顯然機械零部件不都是相對規(guī)則簡單的立體，但這是個有意思的問題。首先界定下問題，題目中的“機械零部件”都指什么呢？首先機械讓人想到的應(yīng)該是運動機構(gòu)，人類想要實現(xiàn)的運動多數(shù)只有直線運動和圓周運動，自然零件就要是柱體和旋轉(zhuǎn)掃略體。而就算想要實現(xiàn)曲線運動，實際上簡單的四連桿機構(gòu)就能在精度滿足要求的情況下擬合絕大多數(shù)的平面閉合曲線了。而且再加上電控器件越來越便宜，我們也沒必要設(shè)計太復(fù)雜的機構(gòu)，三坐標機器人又好又便宜。齒輪、鍵這這些首先都是零件，而不是部件，這樣解構(gòu)的話，復(fù)雜的零部件總能拆成簡單形狀。當然齒輪的漸開線線型已經(jīng)很復(fù)雜了。但另外一個重要原因，這些零件都是通用零件，保證通用就會變得簡單。太復(fù)雜的看都看不懂也就沒人用了不是。除去上面的原因，其實**零件也會變得簡單。這里成本導(dǎo)致的工藝選擇占了很大原因。比如小批量產(chǎn)品能用激光切割鈑金折彎，就絕不會機加工實現(xiàn)，變成一堆直棱直角帶著好多洞的鐵片。機加工的話，能用3軸床絕不用5軸，能做水平的不要做斜的，浪費空間不說，還不方便測量呢。再比如題主提到的鍵，鍵槽用端銑刀劃一下就出來了，別的形狀就不行了。而且絕大多數(shù)零件遠沒到追求性能極限的時候。五金金屬機械性能——延伸率；</p><div

冷加工則一般是在常溫下加工，這種加工方式不會引起工件任何的化學或是物相變化。在對精密機械進行加工作業(yè)之前，工作人員需先根據(jù)加工對象而制定好加工所應(yīng)用的工藝。 </p> <p> 公司秉承“誠信鑄造品質(zhì)，創(chuàng)新未來”的經(jīng)營理念，致力于為客戶提供質(zhì)的服務(wù)。青浦區(qū)管道零部件類別</p><p
