36氪獲悉，智能焊絲層繞設(shè)備制造商長(zhǎng)沙衡開(kāi)智能科技有限公司（以下簡(jiǎn)稱(chēng)：“衡開(kāi)智能”）近日完成由千乘資本領(lǐng)投的3000萬(wàn)元Pre-A輪融資，此輪融資資金將用于產(chǎn)品研發(fā)和團(tuán)隊(duì)拓展。焊絲從制造完成到出廠銷(xiāo)售，還必須經(jīng)歷精密層繞成盤(pán)這一步驟，即將原本一根根分散的焊絲通過(guò)機(jī)器繞成固定規(guī)格的焊絲線盤(pán)，然后再出廠售賣(mài)到客戶(hù)手上。焊絲層繞是焊絲生產(chǎn)必不可少的環(huán)節(jié)，其技術(shù)難點(diǎn)在于首絲和尾絲進(jìn)入、打結(jié)，以及盤(pán)繞時(shí)的張力度控制，張力過(guò)大可能會(huì)引起的焊絲盤(pán)變形和炸盤(pán)現(xiàn)象，過(guò)小則會(huì)使得盤(pán)繞速度過(guò)慢和松盤(pán)問(wèn)題。衡開(kāi)智能董事長(zhǎng)鄒湘衡告訴36氪，目前在焊絲層繞作業(yè)當(dāng)中，主要是兩個(gè)工人搭配一臺(tái)半自動(dòng)層繞設(shè)備進(jìn)行繞線工作，以一個(gè)中20公斤的，整個(gè)成盤(pán)周期在，在這簡(jiǎn)短的時(shí)間里，工人要完成20公斤材料的上小料工作，還需要手動(dòng)矯正機(jī)器盤(pán)絲時(shí)的排列問(wèn)題，以及手工完成首絲和尾絲的切斷和固定。這項(xiàng)工作枯燥而勞累，已經(jīng)出現(xiàn)了年輕工人斷層的情況。而成立于2017年7月的衡開(kāi)智能正是針對(duì)半自動(dòng)化層繞機(jī)的缺點(diǎn)，研發(fā)了全自動(dòng)的復(fù)繞機(jī)器人。這個(gè)機(jī)器人可以全自動(dòng)一體化完成金屬焊絲線材的上盤(pán)、穿絲、精密層繞、停機(jī)、剪斷、折彎、固定、下盤(pán)的工作。河南焊條焊絲廠家藥芯焊絲是很有發(fā)展前途的新型焊接材料，國(guó)產(chǎn)藥芯焊絲的品種和用量與日俱增。</p><div

鑄造是機(jī)械制造的基礎(chǔ)工藝技術(shù)，由于種種原因在生產(chǎn)過(guò)程中會(huì)存在缺點(diǎn)，廢品率較高。另外，在各種機(jī)械裝備中的鑄鐵件在使用過(guò)程中極易損壞。由于鑄鐵的焊接性差，焊后常有氣孔，易變形，易斷裂，易產(chǎn)生白口化和焊接裂紋，從而給鑄件的修復(fù)產(chǎn)生相當(dāng)?shù)碾y度。到目前為止，國(guó)際國(guó)內(nèi)對(duì)此尚沒(méi)有解決的理論及方法。C808鑄鐵常溫焊接焊絲，經(jīng)實(shí)踐證明能有效地解決了鑄鐵件在焊接過(guò)程中產(chǎn)生的上述問(wèn)題，得到了用戶(hù)的一致好評(píng)。C808鑄鐵常溫焊接焊絲可從理論及工藝上解決以下幾個(gè)方面的問(wèn)題：（1）白口問(wèn)題C808鑄鐵常溫焊接焊絲，采用CO2保護(hù)半自動(dòng)焊接技術(shù)，電流密度大，焊后冷卻速度快，母材與焊絲熔合區(qū)硬化層從金相分析看，白口層分析是斷續(xù)的，厚度均〈。（按照國(guó)際慣例，白口層厚度如果〈1mm，對(duì)鑄件加工切削刀具無(wú)影響，基本可以忽略不計(jì)）。（2）焊接產(chǎn)生熱裂紋的問(wèn)題∶通常對(duì)鑄鐵件的焊補(bǔ)，一般都要對(duì)所焊鑄鐵件進(jìn)行局部快速加熱，加熱過(guò)程中溫度不均是必然的，當(dāng)熱應(yīng)力大于被焊件鑄鐵抗拉強(qiáng)度時(shí)，就必然產(chǎn)生熱裂紋。在設(shè)計(jì)C808鑄鐵常溫焊接焊絲化學(xué)成分時(shí)，使用屈服極限比較低可<200MPa，比較高可達(dá)400-500MPa，對(duì)在焊接過(guò)程中產(chǎn)生應(yīng)力并超過(guò)200MPA時(shí)。</p><p> 通過(guò)外力很快就形成小部份短路移動(dòng)工件上去，由于熔化得少，工件與之相比大很多。溫度很快就散發(fā)掉了。焊絲溫度不會(huì)持續(xù)上升至其整段發(fā)紅，抗紅能力超.強(qiáng)。與普通焊絲相比，如果持續(xù)時(shí)間過(guò)長(zhǎng)，就會(huì)出現(xiàn)焊絲嚴(yán)重發(fā)紅，焊點(diǎn)發(fā)黑現(xiàn)象。就算能焊，焊補(bǔ)的時(shí)候，容易出現(xiàn)氧化，掉渣，焊不高等現(xiàn)象.，并且影響其后續(xù)加工。焊絲CO2焊編輯二氧化碳?xì)怏w保護(hù)電弧焊（簡(jiǎn)稱(chēng)CO2焊）的保護(hù)氣體是二氧化碳（有時(shí)采用CO2+O2的混合氣體）。由于二氧化碳?xì)怏w的0熱物理性能的特殊影響，使用常規(guī)焊接電源時(shí)，焊絲端頭熔化金屬不可能形成平衡的軸向自由過(guò)渡，通常需要采用短路和熔滴縮頸爆斷、因此，與MIG焊自由過(guò)渡相比，飛濺較多。但如采用優(yōu)質(zhì)焊機(jī)，參數(shù)選擇合適，可以得到很穩(wěn)定的焊接過(guò)程，使飛濺降低到最小的程度。由于所用保護(hù)氣體價(jià)格低廉，采用短路過(guò)渡時(shí)焊縫成形良好，加上使用含脫氧劑的焊絲即可獲得無(wú)內(nèi)部缺點(diǎn)的高質(zhì)量焊接接頭。因此這種焊接方法目前已成為黑色金屬材料最重要焊接方法之一。CO2立焊雙面成形焊絲型號(hào)編輯常用的焊絲型號(hào)：常見(jiàn)的氣體保護(hù)藥芯焊絲有：LQ122、LQ172、LQ212、LQ337、LQ423、LQ439、LQ451、LQ537、LQ582、LQ585、LQ605、LQ621、LQ666、LQ707等。實(shí)芯焊絲的分類(lèi)及特點(diǎn)

能使焊縫產(chǎn)生變形并使應(yīng)力下降，從而最有效地防止熱裂紋的出現(xiàn)。（3）熔合性問(wèn)題∶有些鑄鐵，由于“石墨”粗大，在高溫或者油環(huán)境中工作，在焊補(bǔ)過(guò)程中會(huì)有一定程度影響熔合性，嚴(yán)重時(shí)出現(xiàn)打滾而無(wú)法焊接。本焊絲焊補(bǔ)過(guò)程中能促使“石墨”燃燒，燃燒產(chǎn)生的CO可促使熔池沸騰而使熔合性大.大改變，焊接后焊縫組.織能跟基體組.織完全融合或部分熔合，結(jié)合緊密。（4）焊前不予熱，焊后不需熱處理消除應(yīng)力或退火降低加工區(qū)硬度問(wèn)題。由于C808鑄鐵常溫焊接焊絲及焊接工藝上的改進(jìn)，采取在焊縫兩端覆蓋退火焊道，消除了基材中的熱應(yīng)力集中點(diǎn)，焊接后不需進(jìn)行消除應(yīng)力或退火降低加工區(qū)硬度熱處理。C808常溫鑄鐵焊接焊絲對(duì)鑄鐵件加工面缺點(diǎn)進(jìn)行修復(fù)的方法在待焊部位開(kāi)出坡口，坡口表面加工,使表面光澤，便于使焊接電弧燒到坡口面的任何地方，對(duì)焊后凡要加工的地方，均用退火焊道覆蓋，焊接規(guī)范的選用原則為在確保熔合的前提下，采用本焊絲和小電流(40-60A)的CO2氣體保護(hù)常溫焊接，焊接工作按鑄鐵常溫焊接要領(lǐng)進(jìn)行。采用C808常溫鑄鐵焊接焊絲對(duì)鑄鐵件加工面缺點(diǎn)進(jìn)行修復(fù)獨(dú)到之處焊前不預(yù)熱，焊后也不需熱處理，焊后可直接上機(jī)械加工線進(jìn)行切削加工，包括能在焊區(qū)鉆小孔和攻絲。?焊絲溫度不會(huì)持續(xù)上升至其整段發(fā)紅，抗紅能力超.強(qiáng)。江蘇卡斯特林焊條焊絲生產(chǎn)廠</p><p
