style="text-indent:25px">彈簧是一種利用彈性來(lái)工作的機(jī)械零件。用彈性材料制成的零件在外力作用下發(fā)生形變，除去外力后又恢復(fù)原狀。亦作“ 彈簧 ”。一般用彈簧鋼制成。彈簧的種類復(fù)雜多樣，按形狀分，主要有螺旋彈簧、渦卷彈簧、板彈簧、異型彈簧等。彈簧歷史：像大多數(shù)其他的基本機(jī)制，金屬?gòu)椈纱嬖谝丫玫那嚆~時(shí)代。即使是金屬，木材被用作一個(gè)靈活的弓箭和彈射器的結(jié)構(gòu)構(gòu)件。在文藝復(fù)興時(shí)期的，精確的鐘表，使得精密彈簧第1次成為必然。十四世紀(jì)看到了發(fā)展的**性天文導(dǎo)航的精確的時(shí)鐘。世界的探索和征服歐洲殖民大國(guó)繼續(xù)提供動(dòng)力的鐘表匠“科學(xué)與藝術(shù)?；鹌鞯牧硪粋€(gè)領(lǐng)域，推動(dòng)彈簧開(kāi)發(fā)。十八世紀(jì)的工業(yè)**來(lái)臨之際，提出了要大，準(zhǔn)確，廉價(jià)的彈簧。鑒于鐘表匠'彈簧往往手工制造，彈簧大規(guī)模生產(chǎn)材質(zhì)為琴鋼線或者類似的材料。</p><p style="text-indent:25px">冷卷彈簧和熱卷彈簧有什么區(qū)別？主要是生產(chǎn)工藝不同，以壓縮彈簧為例：熱卷彈簧典型工藝：落料---端頭加工（軋扁或鍛扁）---加熱---卷簧---淬火---回火---磨端面---壓縮---（負(fù)荷測(cè)試）---噴丸（清理）---涂裝。冷卷彈簧使用不需要熱處理的材料卷制，點(diǎn)行工藝：卷制→去應(yīng)力退火→兩端面磨削→（拋丸）、（校整）、（去應(yīng)力退火）→立定或強(qiáng)壓處理→檢驗(yàn)→表面防腐處理。熱卷彈簧主要用于大型彈簧的卷制，加熱后容易扭曲成形，回彈性較小，成型后需淬火后回火處理。冷卷彈簧直接用彈簧鋼絲卷繞，回彈性較大，卷繞工具需考慮回彈補(bǔ)償量，卷成后直接回火處理。彈簧鋼指的是制造各類彈簧及其他彈性元件的指定合金鋼。</p><div

style="text-indent:25px">彈簧鋼指的是制造各類彈簧及其他彈性元件的指定合金鋼。按性能要求、使用條件可分為普通合金彈簧鋼和特殊合金彈簧鋼。彈簧鋼具有優(yōu)良的綜合性能，彈簧鋼具有優(yōu)良的冶金質(zhì)量（高的純潔度和均勻性）、良好的表面質(zhì)量（嚴(yán)格控制表面缺陷和脫碳）、精確的外形和尺寸。根據(jù)GB/T 13304《鋼分類》標(biāo)準(zhǔn)，按照基本性能及使用特性一，彈簧鋼屬于機(jī)械結(jié)構(gòu)用鋼；按照質(zhì)量等級(jí)，屬于特殊質(zhì)量鋼，即在生產(chǎn)過(guò)程中需要特別嚴(yán)格控制質(zhì)量和性能的鋼。按照中國(guó)習(xí)慣，彈簧鋼屬于特殊鋼，制作彈簧鋼的時(shí)候技術(shù)要求比較高，過(guò)硬的技術(shù)直接決定品質(zhì)的高低。由于單片碟形彈簧的變形量和負(fù)荷值往往不能滿足使用要求，這時(shí)可以成組使用，組成碟簧組合件（柱）。泰州卷簧</p><p

E愈大，則回彈量愈大。材料的力學(xué)性能不穩(wěn)定時(shí),回彈量也不穩(wěn)彈簧旋繞比和節(jié)距越大，塑性變形就越小，內(nèi)應(yīng)力就越不穩(wěn)定，彈簧直徑和節(jié)距的精確度就越難控制。因此,在卷制旋繞比和節(jié)距大的彈簧時(shí)，各工序的操作應(yīng)特別注意。例如，倒車時(shí)速度要慢，搬運(yùn)卷好的彈簧毛坯時(shí)要輕，在去應(yīng)力退火前盡量少移動(dòng)等。對(duì)于旋繞比大的彈簧毛坯，較好在卷制完畢后固定，隨心軸同時(shí)進(jìn)行去應(yīng)力退火后，再?gòu)男妮S上取下。泰州卷簧</p></p><br
