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。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，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，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。模具焊絲銷售廠線材表面亦需光滑平順且清潔否則將影響送絲的順暢及焊接電流的傳迅。</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。</p><p>

電弧周圍形成多種有害氣體，其中主要有臭氧、氮氧化物、一氧化碳和氟化氫等。臭氧是一種刺激性氣體，呈淡藍(lán)色。濃度較高時(shí)，發(fā)出腥臭味；高濃度臭氧還略帶酸味。臭氧對人體的主要危害是對呼吸道及肺有強(qiáng)烈刺激作用。往往引起咳嗽、胸悶、食欲不振、疲勞無力、頭暈、全身疼痛等，嚴(yán)重時(shí)還會(huì)引起***和肺水腫等。氮氧化物是刺激性氣體。二氧化氮呈紅褐色，具有特殊臭味。氮氧化物對人體的危害主要是對肺組.織的刺激作用。其被吸人呼吸道后，在肺泡內(nèi)逐漸與水作用形成硝酸和亞硝酸，對肺組.織產(chǎn)生強(qiáng)烈刺激和腐蝕作用，引起中毒。慢性中毒的主要癥狀是神經(jīng)衰弱，如***、***、食欲不振、體重下降。濃度高的氮氧化物能引起急性中毒，其中毒輕者，*發(fā)生急性***；重度中毒時(shí)，引發(fā)咳嗽激烈、呼吸困難、虛脫、全身軟弱無力等癥狀。氮氧化物對人體的作用也是可逆的，隨著脫離作業(yè)時(shí)間的增長，其不良影響逐漸減少或消除。在鎢極氬弧焊時(shí)，如果不采取通風(fēng)措施，其濃度往往超過衛(wèi)生標(biāo)準(zhǔn)十幾倍，甚至幾十倍。我國規(guī)定的氮氧化物(換算成二氧化氮)的衛(wèi)生標(biāo)準(zhǔn)為5mg／m3。在焊接過程中，通常臭氧和氮氧化物同時(shí)存在，因此它們的毒性更大。一般情況下。鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強(qiáng)度、延性、硬度及韌性等。安徽特種焊絲</p><p
