對(duì)本實(shí)用新型作進(jìn)一步說(shuō)明：結(jié)合圖1—圖4所示，一種防腐罐用焊條自動(dòng)生產(chǎn)設(shè)備，由塑料擠出機(jī)a、水冷循環(huán)系統(tǒng)b、自動(dòng)切斷機(jī)構(gòu)c、焊條接斗d組成，四者從前到后依次布置。水冷循環(huán)系統(tǒng)b，主要由機(jī)架1、水槽2、焊條導(dǎo)向桿3、水龍頭4、水管5和水泵組成。機(jī)架1上方設(shè)置有長(zhǎng)條形的水槽2，水槽2由水平隔板分割成上層槽2a和下層槽，上層槽2a呈敞開(kāi)狀態(tài)，下層槽為封閉狀態(tài)。在水槽2的兩端設(shè)置有連通槽2c。上層槽2a的前壁、后壁上對(duì)應(yīng)開(kāi)設(shè)有焊條過(guò)孔2b，焊條過(guò)孔的直徑為等邊三角形焊條19邊長(zhǎng)的兩倍到三倍之間，供從塑料擠出機(jī)出來(lái)的焊條通過(guò)，同時(shí)還能確保上層槽2a的冷卻水由焊條過(guò)孔2b流入連通槽2c。限定焊條過(guò)孔的直徑與等邊三角形焊條邊長(zhǎng)之間的關(guān)系，既能確保對(duì)焊條位置的限定，又能確保水流量。在上層槽2a內(nèi)前后間隔安裝有兩根水平設(shè)置的焊條導(dǎo)向桿3，但不限于兩根，對(duì)通過(guò)的焊條進(jìn)行導(dǎo)向。焊條過(guò)孔2b、焊條導(dǎo)向桿3在高度上齊平，確保焊條在水冷過(guò)程中水平地順暢通過(guò)，防止焊條彎曲變形。上層槽2a的冷卻水能經(jīng)焊條過(guò)孔2b流入連通槽2c，并**終流進(jìn)下層槽，再由水泵將下層槽的水泵入與水龍頭4相連的水管5。水龍頭4位于上層槽2a的前壁上方并正對(duì)焊條過(guò)孔2b。</p><p> 控制層間溫度對(duì)避免產(chǎn)生晶問(wèn)腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時(shí)應(yīng)盡量選用小線能量快速焊。層間溫度應(yīng)控制在50~60℃。焊接工藝參數(shù)焊接前將坡口內(nèi)外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數(shù)的選擇，見(jiàn)表4所示。2、焊縫外觀檢驗(yàn)及性能試驗(yàn)焊縫外觀成形良好，尤其是焊縫背面成形美觀，無(wú)焊瘤、未熔合、未焊透等缺點(diǎn)。射線檢測(cè)按照J(rèn)B/T4730《承壓設(shè)備無(wú)損檢測(cè)》標(biāo)準(zhǔn)進(jìn)行，II級(jí)及以上為合格，經(jīng)評(píng)定為合格。力學(xué)性能試驗(yàn)按GB/T228和GB/T2653規(guī)定的試驗(yàn)方法，對(duì)焊接接頭試樣進(jìn)行了拉伸試驗(yàn)和彎曲試驗(yàn)，拉伸實(shí)驗(yàn)結(jié)果如表5所示，彎曲試驗(yàn)結(jié)果如表6所示。實(shí)驗(yàn)結(jié)果為合格。3、焊接操作要領(lǐng)不銹鋼藥芯焊絲是利用焊絲中間的藥粉熔化后，在熔敷金屬背面和正面形成熔渣進(jìn)行保護(hù)，所以根部焊接時(shí)與實(shí)芯焊絲焊接的操作方法、電弧擺動(dòng)頻率、填絲量有較大區(qū)別。（1）在焊接過(guò)程中，焊要做圓弧形擺動(dòng),其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時(shí)也可增加母材坡口兩側(cè)的熱輸入量，防止出現(xiàn)單邊未熔合。在填充焊絲時(shí)，應(yīng)將焊絲送到熔池根部并向下輕壓一下，以保證根部熔透及根部?jī)?nèi)成形。。?焊絲焊補(bǔ)時(shí)熱影響區(qū)非常小，不會(huì)產(chǎn)生內(nèi)應(yīng)力。</p><div
