65Mn成分簡(jiǎn)單，淬透性和綜合力學(xué)性能、脫碳等工藝性能均比碳鋼好，但對(duì)過(guò)熱比較敏感，有回火脆性，淬火易出裂紋價(jià)格較低，用量很大。制造各種小截面扁簧、圓簧、發(fā)條等，亦可制氣門(mén)彈簧、彈簧環(huán)，減振器和離合器簧片、剎車(chē)簧等。</p><p style="text-indent:25px">熱軋彈簧鋼材有圓鋼、方鋼、扁鋼等。鋼材表面質(zhì)量要求較高，可以熱軋態(tài)交貨或者經(jīng)熱處理后交貨，以保證硬度不超過(guò)規(guī)定值，便于制簧。熱軋材可以冷態(tài)制成螺旋彈簧，對(duì)于截面尺寸較大者需加熱后制成彈簧。彈簧成型后再經(jīng)淬火、中溫回火，回火溫度約為350～550℃，以獲得較高屈強(qiáng)比和良好的綜合力學(xué)性能。因熱軋材截面尺寸較大，故應(yīng)采用淬透性足夠高的牌號(hào)，保證心部淬透。若心部出現(xiàn)非馬氏體轉(zhuǎn)變產(chǎn)物，如鐵素體、貝氏體等，則回火后的性能降低，特別是疲勞性能。冷拉（軋）彈簧鋼材包括鋼絲、鋼帶。這類(lèi)鋼材的表面質(zhì)量和尺寸精度要求格外嚴(yán)格。鋼絲的生產(chǎn)工藝有油淬火和冷拉兩種。普通碟形彈簧分為有支撐面和無(wú)支撐面兩類(lèi)。</p><div

彈簧指數(shù)減小會(huì)導(dǎo)致局部應(yīng)力過(guò)大。另外，彈簧指數(shù)較大或較小時(shí)，加工性也成問(wèn)題。因此，熱軋成形時(shí)，彈簧指數(shù)可在4～15的范圍內(nèi)選擇。冷軋成形時(shí)，彈簧指數(shù)可在4～22的范圍內(nèi)選擇。（2）縱橫比為了確保有效圈數(shù)，壓縮彈簧的縱橫比(自由高度與螺旋平均直徑之比)可設(shè)定為0.8以上，另外，在考慮到端部磨平圈的情況下，一般可在0.8～4的范圍內(nèi)選擇。（3）有效圈數(shù) 如果有效圈數(shù)為3以下，彈簧特性則會(huì)變得不穩(wěn)定，因此應(yīng)將彈簧指數(shù)設(shè)定為3以上。（4）節(jié)距節(jié)距超過(guò)0.5D時(shí)，由于螺旋直徑通常會(huì)隨著撓曲量(負(fù)載)的增加而發(fā)生變化，需要對(duì)利用基本公式求出的撓曲量與扭轉(zhuǎn)應(yīng)力進(jìn)行修正，因此應(yīng)將節(jié)距設(shè)定為0.5D以下。一般說(shuō)來(lái)，節(jié)距利用下述簡(jiǎn)算式進(jìn)行推算。碳素彈簧鋼:碳素彈簧鋼的碳含量（質(zhì)量分?jǐn)?shù)）一般在0.62%~0.90%。s形彈簧型號(hào)</p><p
