<span style="font-size:36px;"><a href="http://www.caoepaperfe.cn">芯棒</a>的用處和介紹</span></h3> </div> <div> <span style="font-size:22px;">新型彎頭芯棒模具主要是用于推制彎頭不厚不會(huì)減薄，使用等壁厚重量的鋼管進(jìn)行等壁厚的彎管推制就可以了。大大降低材料生產(chǎn)成本。</span></div> <div> <span style="font-size:22px;">新型彎頭蜜桔推制的彎頭不需要用壓力機(jī)進(jìn)行二次整形，其角度直接就是標(biāo)準(zhǔn)的。新型芯棒推制彎頭時(shí)間短，提高生產(chǎn)效率，新型芯棒具有傳統(tǒng)模具生產(chǎn)成本降低了30%左右，生產(chǎn)效率提高了一到二被倍。</span></div> <div> <span style="font-size:22px;">芯棒的材質(zhì)一般有K18，2520 18-8 ，304等等，高溫強(qiáng)度及耐磨性逐漸升高。價(jià)格也是相應(yīng)升高，推制彎頭芯棒頭按曲率半徑分為單曲率，雙曲率和多曲率三種。單曲率，雙曲率，多曲率芯棒，推力逐漸減小，制作成本逐漸升高、本次檢驗(yàn)選雙曲率芯棒。按截面形狀分為圓截面兩種。圓截面制作簡(jiǎn)單，成本低。但推制彎頭的橢圓度及減薄率過大，橢圓截面制作復(fù)雜，成本高，但同對(duì)焊彎頭有所不同，推制彎頭的橢圓度及減薄流程小。本次選橢圓截面芯棒，按是否有整形段分為有整形段芯棒和無(wú)整形段芯棒兩種。有整形段芯棒制作復(fù)雜，成本高，使用時(shí)間長(zhǎng)，無(wú)整形芯棒制作簡(jiǎn)單成本低。我們公司又專業(yè)人員調(diào)試出成品彎頭。我們的產(chǎn)品很受客戶的信賴和好評(píng)，成為很多客戶的合作伙伴。</span></div> <div> <span style="font-size:22px;">本公司主要生產(chǎn)彎頭機(jī)，彎管機(jī)，三通機(jī),擴(kuò)管機(jī),坡口機(jī),壓力機(jī)等以上管件設(shè)備的模具.擁有完整的科學(xué)質(zhì)量和管理，獲得認(rèn)可很多客戶的認(rèn)可。我們公司可以根據(jù)客戶的需要直接定做各種型號(hào)的彎頭芯棒。</span></div> <div> <span style="font-size:22px;">我們公司生產(chǎn)的彎頭芯棒的型號(hào)是60-610，彎頭芯棒的材質(zhì)一般是K18,2520 .18-8.304 等。本公司生產(chǎn)的模具提高生產(chǎn)效率，使用時(shí)間長(zhǎng)。<a
