本實(shí)用新型涉及一種用于制造防腐罐焊條的自動(dòng)生產(chǎn)線。背景技術(shù)：防腐罐本體為pph聚丙烯材質(zhì)，采用pph聚丙烯的焊條焊接成型，焊條橫截面為等邊三角形。防腐罐焊條通過塑料擠出機(jī)制作，焊條經(jīng)塑料擠出機(jī)成型后再人工剪切成條。但是塑料擠出機(jī)出來的焊條溫度較高，人工剪切不便于握持，且對尚未降溫的焊條進(jìn)行剪切易造成焊條變形；但若不及時(shí)進(jìn)行剪切，源源不斷出來的焊條又無處放置，SM2R焊絲生產(chǎn)廠。技術(shù)實(shí)現(xiàn)要素：本實(shí)用新型旨在提供一種防腐罐焊條的自動(dòng)生產(chǎn)線，能對塑料擠出機(jī)出來的pph聚丙烯焊條進(jìn)行及時(shí)冷卻及自動(dòng)剪切成條，并確保焊條質(zhì)量。為此，本實(shí)用新型所采用的技術(shù)方案為：一種防腐罐用焊條自動(dòng)生產(chǎn)設(shè)備，包括塑料擠出機(jī)，還包括水冷循環(huán)系統(tǒng)和自動(dòng)切斷機(jī)構(gòu)，三者從前到后依次布置；所述水冷循環(huán)系統(tǒng)包括機(jī)架，所述機(jī)架上方設(shè)置有長條形的水槽，SM2R焊絲生產(chǎn)廠，所述水槽由水平隔板分割成敞開的上層槽和封閉的下層槽，在水槽的兩端設(shè)置有連通槽，所述上層槽的前壁、后壁上對應(yīng)開設(shè)有焊條過孔，SM2R焊絲生產(chǎn)廠，且焊條過孔的直徑為等邊三角形焊條邊長的兩倍到三倍之間，在上層槽內(nèi)前后間隔安裝有至少兩根水平設(shè)置的焊條導(dǎo)向桿，且焊條過孔、焊條導(dǎo)向桿在高度上齊平，所述上層槽的冷卻水能經(jīng)焊條過孔流入連通槽。藥芯焊絲是很有發(fā)展前途的新型焊接材料，國產(chǎn)藥芯焊絲的品種和用量與日俱增。SM2R焊絲生產(chǎn)廠</p><div

1、焊接方法板狀仰焊的焊接有2種方法：連弧法及熄弧法。連弧法是通過連續(xù)而有規(guī)則地?cái)[動(dòng)焊條進(jìn)行短弧施焊的操作方法；熄弧法是在封底焊時(shí)采用電弧燃燒一定時(shí)即行熄滅，然后再引燃、再熄滅，從而使熔池金屬迭加成形的方法。這2種方法各有所長。熄弧法可以保證封底焊縫有良好的成形，能有效地控制焊縫下垂、頂面內(nèi)凹，缺點(diǎn)是由于焊接過程處于間斷狀態(tài)，容易出現(xiàn)氣孔、夾渣等缺點(diǎn)。連弧法可以使焊接過程連續(xù)化，能夠有效地保證焊接質(zhì)量，但操作方法不當(dāng)將會(huì)造成焊縫下垂，表面內(nèi)凹。比較2種焊接方法，連弧焊更值得推廣。在一些工業(yè)發(fā)達(dá)國家，如德國、美國、日本等，生產(chǎn)中都要求采用這種焊接方法。2試板及工藝要求試板要求試板材質(zhì)為Q235B，規(guī)格為100mm×12mm×300mm。采用E5015（J507）焊條，焊接位置為仰焊，要求單面焊雙面成形。坡口形式如圖1所示。焊接工藝參數(shù)焊接工藝參數(shù)見表1。表1焊接工藝參數(shù)焊條角度施焊過程中焊條與焊接方向的夾角如圖2所示。3、焊接操作要點(diǎn)封底層的焊接對整個(gè)試板而言，封底層的焊接是關(guān)鍵，在焊接過程中，焊接熔池金屬的自身重力在電弧作用力和液態(tài)金屬的表面張力作用下處于平衡狀態(tài)。具體操作是地。江蘇鈷基焊絲銷售廠絕大部分的藥芯焊絲均由一扁平金屬薄片長條逐段經(jīng)過滾卷成U型斷面。</p><div

焊條電弧焊從焊接電弧的基礎(chǔ)講起，按“有認(rèn)知、易學(xué)會(huì)、好掌握、能操作”的原則，由淺入深、循序漸進(jìn)地講解了焊條電弧焊的工藝?yán)碚摵蛯?shí)操技能。本書主要內(nèi)容包括：焊接技術(shù)基礎(chǔ)知識(shí)、焊條電弧焊設(shè)備、焊條的組成和分類、焊條的型號(hào)與牌號(hào)、常用焊條焊接工藝性能及選用原則、焊條的正確保管與貯存、焊條電弧焊基本工藝知識(shí)、焊接冶金基本知識(shí)、焊接接頭的組.織與性能、焊條電弧焊常見焊接缺點(diǎn)及其防止、典型管類和管板類焊接技術(shù)、碳弧氣刨。一、焊條電弧焊的操作焊條電弧焊**基本的操作是引弧、運(yùn)條和收尾(一)引弧引弧即產(chǎn)生電弧。焊條電弧焊是采用低電壓、大電流放電產(chǎn)生電弧，依靠電焊條瞬時(shí)接觸工件實(shí)現(xiàn)。引弧時(shí)必須將焊條末端與焊件表面接觸形成短路，然后迅速將焊條向上提起2～4mm的距離，此時(shí)電弧即引燃。引弧的方法有兩種：碰擊法和擦劃法，詳見圖3—14引弧方法(1)碰擊法。也稱點(diǎn)接觸法或稱敲擊法。碰擊法是將焊條與工件保持一定距離，然后垂直落下，使之輕輕敲擊工件，發(fā)生短路，再迅速將焊條提起，產(chǎn)生電弧的引弧方法。此種方法適用于各種位置的焊接。(2)擦劃法。也稱線接觸法或稱摩擦法。擦劃法是將電焊條在坡口上滑動(dòng)，成一條線，當(dāng)端部接觸時(shí)，發(fā)生短路。</p><p> 焊條介紹及1、焊芯及藥皮涂有藥皮的供手弧焊用的熔化電極，叫做焊條。焊條由藥皮和焊芯兩大部分所組成。焊條端部有一段沒有藥皮的夾持端，被焊鉗夾住后可以傳導(dǎo)電流（藥皮不導(dǎo)電），焊條末端的藥皮磨成錐形，便于焊接時(shí)引弧。焊條上端藥皮處印有該焊條的型號(hào)或牌號(hào)，以便焊工使用時(shí)識(shí)別。（1）焊芯碳素結(jié)構(gòu)鋼和低合金結(jié)構(gòu)鋼焊接用的焊條，其焊芯材料為低碳鋼。常用牌號(hào)為H08A，含義如下：H08A焊芯的化學(xué)成分，見表3-1。碳在焊接過程中會(huì)引起飛濺，并使焊縫產(chǎn)生氣孔和裂紋，所以必須限制焊芯中碳的含量。焊芯的長度與焊芯的直徑（即焊條的直徑）有關(guān)，見表3-2。焊芯直徑越細(xì)，電阻越大，焊接時(shí)由于電流通過焊芯所產(chǎn)生的電阻熱也越大，使藥皮發(fā)紅變質(zhì)，所以其長度就越短。生產(chǎn)中常用的焊芯直徑是，，。（2）藥皮在焊接過程中藥皮的作用是：1）使電弧穩(wěn)定燃燒。2）產(chǎn)生熔渣和氣體，防止空氣中的氧、氮侵入焊縫金屬，以提高焊縫質(zhì)量。3）產(chǎn)生的熔渣覆蓋在焊縫上，使焊縫表面成形良好。4）通過熔渣與熔化金屬之間的化學(xué)反應(yīng)，能增加焊縫金屬中合金元素的含量，改善和提高焊縫金屬的力學(xué)性能。二氧化碳?xì)怏w保護(hù)電弧焊（簡稱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）。</p><div

電感線圈的感抗電壓降使電焊機(jī)獲得較低的工作電壓，這是電焊機(jī)具有陡降外特性的原因。引弧時(shí)，電焊機(jī)能供給較高的電壓和較小的電流，當(dāng)電弧穩(wěn)定燃燒時(shí)，電流增大，而電壓急劇降低；當(dāng)焊條與工件短路時(shí)，也限制了短路電流。焊接電流調(diào)節(jié)分為粗調(diào)、細(xì)調(diào)兩檔。電流的細(xì)調(diào)靠移動(dòng)鐵芯4改變變壓器的漏磁來實(shí)現(xiàn)。向外移動(dòng)鐵芯，磁阻增大，漏磁減小，則電流增大，反之，則電流減少。電流的粗調(diào)靠改變次級(jí)繞組的匝數(shù)來實(shí)現(xiàn)。該電弧焊機(jī)的工作條件為應(yīng)在海拔不超過1000m，周圍空氣溫度不超過+40℃、空氣相對濕度不超過85％等條件下使用，不應(yīng)在有害工業(yè)氣體、水蒸汽、易燃、多灰塵的場合下工作。二、直流弧焊機(jī)(一)結(jié)構(gòu)由于整流或直流弧焊機(jī)與直流弧焊發(fā)電機(jī)比較，因沒有機(jī)械旋轉(zhuǎn)部分，具有噪音小，空載損耗小、效率高、成本低和制造維護(hù)簡單等優(yōu)點(diǎn)。因此，有取代直流弧焊發(fā)電機(jī)的趨勢，在這里只介紹整流式直流弧焊機(jī)。整流式直流弧焊機(jī)常用型號(hào)如ZXG—300、ZXG—400等。硅整流電弧焊機(jī)是利用硅半導(dǎo)體整流元件(二極管)將交流電變?yōu)橹绷麟娮鳛楹附与娫?。圖3—10為硅整流電弧焊機(jī)的結(jié)構(gòu)示意圖。按照“先進(jìn)先出”的原則發(fā)放焊絲，盡量減少產(chǎn)品庫存時(shí)間。江蘇鈷基焊絲銷售廠</p><p

焊條烘干的目的焊條在儲(chǔ)存、運(yùn)輸期間藥皮會(huì)吸潮，使藥皮中的水分增加。焊條使用前進(jìn)行烘干的作用就是降低藥此中的含水量，其目的是：1）減少焊接過程中的飛濺，使焊接電弧能夠穩(wěn)定地燃燒。2）防止在焊縫中產(chǎn)生氣孔。3）防止產(chǎn)生在焊接某些低合金鋼時(shí)由氫引起的延遲裂紋。根據(jù)JB3223—83《焊條質(zhì)量管理規(guī)程》的規(guī)定，酸性焊條烘干的溫度為75～150℃時(shí)間為1～2h。酸性焊條由于對水分產(chǎn)生氣孔的敏感性不大，所以烘干溫度相對要低一些。堿性焊條的烘干溫度350--400℃，時(shí)間1--2小時(shí)，烘干后放在100--150℃的保溫箱內(nèi)，隨用隨取。JB4709中有推薦保溫時(shí)間和溫度(非強(qiáng)制性標(biāo)準(zhǔn)),不過實(shí)際使用時(shí)比較好參考焊條質(zhì)保書中的溫度及時(shí)間要求！堿性焊條過高的烘干溫度也是不合適的：一是浪費(fèi)能源；其次是當(dāng)烘干溫度超過500℃時(shí)，藥皮中的某些成分（如CaCO3）就要發(fā)生分解，起不到應(yīng)有的保護(hù)作用。焊條烘干時(shí)的注意事項(xiàng)焊條烘干時(shí)應(yīng)注意如下事項(xiàng)：1）低氫型焊條在常溫下超過4h時(shí)，應(yīng)重新烘干。重復(fù)烘干次數(shù)不宜超過3次。2）烘干焊條時(shí)，禁止將焊條突然放進(jìn)高溫爐內(nèi)，或從高溫爐中突然取出冷卻，防止焊條因驟冷驟熱而發(fā)生的藥皮開裂現(xiàn)象。3）焊條烘干時(shí)應(yīng)作記錄。SM2R焊絲生產(chǎn)廠</p><p
