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)。絲光直輥纖維溶脹后,大分子間的氫鍵被拆散。</p><div style="width:100%;text-align:

style="text-indent:25px">矯直處理目前只針對(duì)盤(pán)條鋼筋，由于盤(pán)條在鋼廠的軋制、收卷、熱處理、運(yùn)輸、堆放等過(guò)程中容易產(chǎn)生殘余應(yīng)力。而直條鋼筋相對(duì)盤(pán)條鋼筋情況大不相同，一般可直接投入生產(chǎn)。在工廠化的鋼筋加工中，鋼筋平直性尤為重要，其涉及后續(xù)的配送、彎曲、焊接等各項(xiàng)生產(chǎn)要素。目前的鋼筋矯直都是采用矯直機(jī)進(jìn)行矯直。蟬蛹的矯直機(jī)構(gòu)有兩種：輥式矯直機(jī)構(gòu)和旋轉(zhuǎn)式矯直機(jī)構(gòu)。輥式矯直機(jī)構(gòu)結(jié)構(gòu)較為簡(jiǎn)單，成本低，但矯直效果較差，對(duì)鋼筋內(nèi)部殘余應(yīng)力的去掉不夠徹底。旋轉(zhuǎn)矯直機(jī)構(gòu)結(jié)構(gòu)較為復(fù)雜，成本高，還需配備旋轉(zhuǎn)動(dòng)力能耗較高，但矯直效果好，對(duì)鋼筋的環(huán)向應(yīng)力去掉的較為徹底。這兩種矯直機(jī)構(gòu)在鋼筋加工設(shè)備上得到大量的應(yīng)用。絲光直輥的輥型是根據(jù)輥與管接觸的空間幾何關(guān)系確定的。上海絲光直輥廠商</p><p
