style="text-indent:25px">卷簧是利用扁形材料進(jìn)行卷制成形的簡稱。卷簧是彈簧制造的第-道工序，也是重要的工序，卷制的精度對整個制造過程起著極為重要的作用，它基本上決定了彈簧的幾何尺寸和特性以及材料的利用率。彈簧的卷制設(shè)備-般分有心軸卷制彈簧機(jī)與無心軸卷制彈簧機(jī)，卷制方式有單個卷制和多個連續(xù)卷制。單個卷制一般用于條料制造的彈簧以及油封彈簧等;多個連續(xù)卷制是一次卷成一串螺旋彈簧,然后按尺寸分別切斷成單個彈簧。為了在冷成形后得到所要求的尺寸精度,在彈簧設(shè)計、彈簧工藝裝置設(shè)計和編制工藝規(guī)程時，必須準(zhǔn)確地掌握不同材料的各類彈簧在成形時的回彈量。</p><p style="text-indent:25px">不銹鋼彈簧同彈簧一樣是機(jī)械和電子行業(yè)中普遍使用的一種彈性元件，彈簧在受載時能產(chǎn)生較大的彈性變形，把機(jī)械功或動能轉(zhuǎn)化為變形能，而卸載后彈簧的變形消失并回復(fù)原狀，將變形能轉(zhuǎn)化為機(jī)械功或動能。適用在要求防腐，耐溫，無磁等范圍。按受力性質(zhì)，不銹鋼彈簧可分為拉伸彈簧、壓縮彈簧、扭轉(zhuǎn)彈簧和彎曲彈簧，按形狀可分為碟形彈簧、環(huán)形彈簧、板彈簧、螺旋彈簧、截錐渦卷彈簧以及扭桿彈簧等。普通圓柱彈簧由于制造簡單，且可根據(jù)受載情況制成各種型式，結(jié)構(gòu)簡單，故應(yīng)用較廣。彈簧的一般來說應(yīng)具有高的彈性極限、疲勞極限、沖擊韌性及良好的耐熱耐腐蝕性能等，常用彈簧絲直徑20毫米以下的用冷卷法，有些彈簧在制成后還要進(jìn)行強(qiáng)壓或噴丸處理，可提高彈簧的承載能力。彈簧秤又叫彈簧測力計，是一種利用彈簧在被測物重力作用下的變形來測定該物質(zhì)量的衡器。</p><div

style="text-indent:25px">彈簧卷制方式有單個卷制和多個連續(xù)卷制。單個卷制一般用于條料制造的彈簧以及油封彈簧等；多個連續(xù)卷制是一次卷成一串螺旋彈簧，然后按尺寸分別切斷成單個彈簧。為了在冷成形后得到所要求的尺寸精度，在彈簧設(shè)計、彈簧工藝裝置設(shè)計和編制工藝規(guī)程時，必須準(zhǔn)確地掌握不同材料的各類彈簧在成形時的回彈量。影響回彈量的因素很多，主要有材料的力學(xué)性能、彈簧的旋繞比和工藝裝置等?；貜椓颗c材料的抗拉強(qiáng)度fb成正比，與彈性模量E成反比，σ／E愈大，則回彈量愈大。材料的力學(xué)性能不穩(wěn)定時，回彈量也不穩(wěn)定。氣彈簧是一種可以起支撐、緩沖、制動、高度調(diào)節(jié)及角度調(diào)節(jié)等功能的工業(yè)配件?；窗簿硎綇椈?/p><p style="text-indent:25px">彈簧的卷制設(shè)備一般分有心軸卷制彈簧機(jī)與無心軸卷制彈簧機(jī)?；⌒螐椈?/p><p style="text-indent:25px">卷簧一般是在不用電能的情況下，作為微小型機(jī)械的動力來使用，比如機(jī)械鐘表的走時動力和報時系統(tǒng)的動力；機(jī)械留聲機(jī)唱片轉(zhuǎn)動的動力；機(jī)械式八音盒；自動演奏鋼琴；上弦類玩具的動力等等。這類卷簧作動力的機(jī)械有共同點就是傳動鏈?zhǔn)巧贆C(jī)構(gòu)，而不是機(jī)械中常用的減速器，另外，由卷簧在上緊時輸出的力矩大，而接近全放松時，輸出的力矩會減小很多，為了減小發(fā)條的這種不均勻的輸出力矩，這類裝置都有一個穩(wěn)速機(jī)構(gòu)，利用它來穩(wěn)定機(jī)構(gòu)的轉(zhuǎn)速。在機(jī)械手表中為了減小這個力矩差，特意將發(fā)條做成自由狀態(tài)時呈S形，而不是平面等距螺旋線形，使卷簧的輸出力矩相對平衡一些?；⌒螐椈?/p></p><br
