1、開(kāi)車(chē)前檢查機(jī)器緊固螺釘有無(wú)松動(dòng)，操縱機(jī)構(gòu)、停止裝置、離合器是否正常，機(jī)床在工作前應(yīng)作空運(yùn)轉(zhuǎn)2-3分鐘，檢查手腳閘等控制裝置的靈活性，確認(rèn)正常后方可使用，不得帶病運(yùn)轉(zhuǎn)。 2、滑動(dòng)及轉(zhuǎn)動(dòng)部位必須加注潤(rùn)滑油，檢查各部件的潤(rùn)滑情況，查看主要潤(rùn)滑系統(tǒng)有無(wú)堵塞或缺油，并使各潤(rùn)滑點(diǎn)得到充分的潤(rùn)滑。 3、正確使用設(shè)備上的安全保護(hù)和控制裝置，暴露于機(jī)器表面的傳動(dòng)部件，必須安裝防護(hù)罩，不得任意拆動(dòng)。開(kāi)機(jī)前檢查沖床防護(hù)裝置是否齊全，禁止在卸下防護(hù)罩的情況下開(kāi)車(chē)或試車(chē)。 4、定時(shí)檢查模具安裝情況，如有松動(dòng)或滑移應(yīng)及時(shí)調(diào)整。安裝模具時(shí)必須將滑塊開(kāi)到下死點(diǎn)，采用手動(dòng)或點(diǎn)動(dòng)的方法調(diào)整閉合高度，防止對(duì)模較深心軸轉(zhuǎn)不過(guò)來(lái)發(fā)生事故；上下沖模必須對(duì)正，保證位置正確，避免偏心安裝；夾持必須牢固、正確，沖壓模副應(yīng)先緊固上模后，操作1次后，無(wú)異常時(shí)再緊固下模。確定模具安裝好之后用手搬轉(zhuǎn)。北京沖床型號(hào)</p><div

style="text-indent:25px">沖床由于潤(rùn)滑不好，工作臺(tái)移動(dòng)時(shí)摩擦阻力增大。當(dāng)電機(jī)驅(qū)動(dòng)時(shí)，工作臺(tái)不向前運(yùn)動(dòng)，使?jié)L珠絲杠產(chǎn)生彈性變形，把電機(jī)的能量貯存在變形上。電動(dòng)機(jī)繼續(xù)驅(qū)動(dòng)，貯存的能量所產(chǎn)的彈性力大于靜摩擦力時(shí)，沖床工作臺(tái)向前蠕動(dòng)，周而復(fù)始地這樣運(yùn)動(dòng)，而產(chǎn)生了爬行的現(xiàn)象。然而事實(shí)并非如此，仔細(xì)看一下導(dǎo)軌面潤(rùn)滑的情況，就可以斷定不是這個(gè)問(wèn)題。沖床爬行和振動(dòng)問(wèn)題是屬于速度的問(wèn)題。既然是速度的問(wèn)題就要去找速度環(huán)，沖床的速度的整個(gè)調(diào)節(jié)過(guò)程是由速度調(diào)節(jié)器來(lái)完成的。</p><p style="text-indent:25px">沖床的設(shè)計(jì)原理是將圓周運(yùn)動(dòng)轉(zhuǎn)換為直線運(yùn)動(dòng)，由主電動(dòng)機(jī)出力，帶動(dòng)飛輪，經(jīng)離合器帶動(dòng)齒輪、曲軸（或偏心齒輪）、連桿等運(yùn)轉(zhuǎn)，來(lái)達(dá)成滑塊的直線運(yùn)動(dòng)，從主電動(dòng)機(jī)到連桿的運(yùn)動(dòng)為圓周運(yùn)動(dòng)。連桿和滑塊之間需有圓周運(yùn)動(dòng)和直線運(yùn)動(dòng)的轉(zhuǎn)接點(diǎn)，其設(shè)計(jì)上大致有兩種機(jī)構(gòu)，一種為球型，一種為銷型（圓柱型），經(jīng)由這個(gè)機(jī)構(gòu)將圓周運(yùn)動(dòng)轉(zhuǎn)換成滑塊的直線運(yùn)動(dòng)。沖床對(duì)材料施以壓力，使其塑性變形，而得到所要求的形狀與精度，因此必須配合一組模具（分上模與下模），將材料置于其間，由機(jī)器施加壓力，使其變形，加工時(shí)施加于材料之力所造成之反作用力，由沖床機(jī)械本體所吸收。

style="text-indent:25px">沖床種類多，而且使用范圍廣，在使用時(shí)除了要按照正確的操作方法操作外，更應(yīng)該注意使用安全，所以掌握安全操作規(guī)程十分重要。 1、沖床工必須經(jīng)過(guò)學(xué)習(xí)，掌握設(shè)備的結(jié)構(gòu)、性能，熟悉操作規(guī)程并取得操作許可方可**操作。 2、正確使用沖床上安全保護(hù)和控制裝置，不得任意拆動(dòng)。 3、檢查機(jī)床各傳動(dòng)、連接、潤(rùn)滑等部位及防護(hù)保險(xiǎn)裝置是否正常，裝模具螺釘必須牢固，不得移動(dòng)。 4、機(jī)床在工作前應(yīng)作空運(yùn)轉(zhuǎn)2-3分鐘，檢查腳閘等控制裝置的靈活性，確認(rèn)正常后方可使用，不得帶病運(yùn)轉(zhuǎn)。 5、模具時(shí)要緊牢固，上、下模對(duì)正，保證位置正確，用手搬轉(zhuǎn)機(jī)床試沖（空車(chē)），確保在模具處于良好情況下工作。 6、沖床開(kāi)車(chē)前要注意潤(rùn)滑，取下床面上的一切浮放物品。 7、沖床取動(dòng)時(shí)或運(yùn)轉(zhuǎn)沖制中，操作者站立要恰當(dāng)，手和頭部應(yīng)與沖床保持一定的距離，并時(shí)刻注意沖頭動(dòng)作，嚴(yán)禁與他人閑談。 8、工作結(jié)束時(shí)及時(shí)停車(chē)，切斷電源，擦拭機(jī)床，整理環(huán)境。北京沖床型號(hào)</p><p style="text-indent:25px">山西40噸沖床</p><p
