mm，可分三次走刀，進(jìn)刀量分別可為0.4 mm、0.3 mm、0.3 mm，這樣有利于降低膠輥表面溫度。由于粗磨對(duì)膠輥表面粗糙度無(wú)嚴(yán)格要求，主要是保證膠輥表面圓柱度。粗磨后不應(yīng)立即進(jìn)行精磨，要將并條膠輥放置48 h，使其經(jīng)時(shí)效處理后進(jìn)行。精磨膠輥時(shí)可選用粒度為60、70、80號(hào)，寬度為30 mm的大氣孔砂輪，磨削總量一般為0.5 mm，棉紡企業(yè)一般*需進(jìn)行復(fù)磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進(jìn)行，進(jìn)刀量分別可為0.2 mm、0.1 mm、0.1 mm，采用小負(fù)荷磨削可使膠輥表面熱量受到控制，磨削粉塵也較少，更有利于砂輪的清潔與鋒利。在砂輪安全線速度的前提下，為保證磨礪質(zhì)量，一般砂輪主軸轉(zhuǎn)速為1800 r/min，相應(yīng)車頭轉(zhuǎn)速約為200 r/min。磨削前需要調(diào)整好磨床尾座，保證磨削后膠輥兩端錐度不大于0.03 mm，磨削行程要設(shè)置為自動(dòng)走刀以保證磨削速度均勻，之后一次走刀速度要慢，以3 m/min～4 m/min為宜。精磨后膠輥膠層應(yīng)細(xì)膩、光滑，目測(cè)其表面無(wú)螺旋線，無(wú)機(jī)械波紋，表面粗糙度Ra值達(dá)到0.4 μm～0.6 μm為好。上海絲光直輥加工廠絲光直輥槽只是替代了軋堿槽和繃布輥的作用而已。</p><div

直輥使用中出現(xiàn)的問(wèn)題在對(duì)并條牽伸通道的日常檢查中，經(jīng)常發(fā)現(xiàn)直輥軸頭跳動(dòng)較大，很多直輥還有軸向游動(dòng)的問(wèn)題，大游動(dòng)量達(dá)到約 4

style="text-indent:25px">絲光直輥是重要的牽伸器材，其中并條直輥和羅拉鉗口對(duì)纖維層的控制作用遠(yuǎn)遠(yuǎn)大于粗紗、細(xì)紗工序，直輥出現(xiàn)問(wèn)題或者直輥與軸承配合不良，都會(huì)導(dǎo)致羅拉和直輥配置不當(dāng)，從而引起紗線條干和重量的變化，這在后道工序無(wú)法改善；在絡(luò)筒工序雖可設(shè)定參數(shù)來(lái)調(diào)整，但對(duì)絡(luò)筒工序的生產(chǎn)效率和產(chǎn)量影響較大。因此，加強(qiáng)對(duì)并條直輥的管理，正確使用、維護(hù)直輥，對(duì)提高成紗質(zhì)量具有重要的意義。1 直輥的作用直輥是現(xiàn)代高速并條機(jī)上的關(guān)鍵器材之一，直輥的傳動(dòng)方式為摩擦傳動(dòng)，在一定壓力下與羅拉形成握持鉗口，從而有效控制纖維的運(yùn)動(dòng)，保證持續(xù)的牽伸運(yùn)動(dòng)。絲光直輥曲面是由絲光直輥與管材接觸時(shí)所形成的空間曲線所確定的。上海絲光直輥公司有哪些</p><p

style="text-indent:25px">磨床對(duì)膠輥的磨礪是通過(guò)砂輪與膠輥精確穩(wěn)定的相對(duì)運(yùn)動(dòng)，由砂輪的微粒鋒刃對(duì)膠輥表面進(jìn)行磨削，磨床和砂輪的質(zhì)量與其穩(wěn)定性直接影響膠輥表面的磨礪質(zhì)量。通常選用粒度為(40～80)號(hào)大氣孔綠碳化硅或碳化硅砂輪，且要選用中低硬度的砂輪，太硬的磨粒變鈍后不能順利脫落，磨削力和熱量增加影響磨礪后膠輥表面質(zhì)量。砂輪使用前必須調(diào)平衡并且修整，砂輪兩棱應(yīng)用舊砂輪或油石倒角。目前，棉紡企業(yè)復(fù)磨并條膠輥使用的大多數(shù)磨床仍為FLJ804型等設(shè)備，其使用年限較長(zhǎng)，磨礪膠輥前應(yīng)確保具有良好的機(jī)械性能，特別是砂輪主軸、車頭主軸的跳動(dòng)應(yīng)不大于0.0l
