一、冷焊機的原理是什么
冷(leng)焊(han)(han)(han)機是(shi)一種焊(han)(han)(han)接設備,因(yin)為焊(han)(han)(han)接后工(gong)(gong)件(jian)表面(mian)溫度較低,因(yin)此(ci)稱(cheng)為冷(leng)焊(han)(han)(han)機,它(ta)的(de)工(gong)(gong)作原理是(shi):利用充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)容(rong),以(yi)(yi)10-3~10–1秒的(de)周期,10-6~10-5秒的(de)超短時間放(fang)電(dian)(dian)(dian)(dian)(dian),微電(dian)(dian)(dian)(dian)(dian)瞬(shun)間放(fang)電(dian)(dian)(dian)(dian)(dian)產生(sheng)的(de)高(gao)熱能,電(dian)(dian)(dian)(dian)(dian)極材(cai)料與(yu)(yu)工(gong)(gong)件(jian)接觸(chu)部位瞬(shun)間會(hui)被(bei)加熱到8000°C~10000°C,等離子化狀態的(de)熔融金屬以(yi)(yi)冶金的(de)方(fang)式過渡到工(gong)(gong)件(jian)的(de)表層,與(yu)(yu)原有(you)(you)基材(cai)牢固熔接,從而達(da)到焊(han)(han)(han)接效果。冷(leng)焊(han)(han)(han)機之(zhi)所以(yi)(yi)能實現冷(leng)焊(han)(han)(han),是(shi)因(yin)為它(ta)的(de)放(fang)電(dian)(dian)(dian)(dian)(dian)時間與(yu)(yu)下一次放(fang)電(dian)(dian)(dian)(dian)(dian)間隔時間相比極短,機器有(you)(you)足夠的(de)相對停止時間,熱量會(hui)通過工(gong)(gong)件(jian)基體擴散到外界,工(gong)(gong)件(jian)的(de)被(bei)加工(gong)(gong)部位不會(hui)有(you)(you)熱量的(de)聚(ju)集。
二、冷焊機優缺點及用途
1、冷(leng)焊(han)(han)(han)(han)(han)機(ji)(ji)(ji)的優點(dian):(1)焊(han)(han)(han)(han)(han)接牢固度(du)等(deng)(deng)(deng)同氬弧(hu)焊(han)(han)(han)(han)(han)機(ji)(ji)(ji),為完全冶金熔(rong)接,焊(han)(han)(han)(han)(han)材(cai)硬(ying)度(du)可(ke)(ke)選(xuan),焊(han)(han)(han)(han)(han)后不(bu)會改(gai)變(bian)焊(han)(han)(han)(han)(han)材(cai)及母材(cai)的各項性(xing)能。(2)修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)精(jing)度(du)高,可(ke)(ke)使(shi)用(yong)直徑(jing)0.3mm至1.6mm圓絲、補(bu)(bu)材(cai)進行修(xiu)(xiu)(xiu)(xiu)補(bu)(bu),不(bu)會失(shi)去原(yuan)基(ji)準面,多余焊(han)(han)(han)(han)(han)料(liao)少,后期整(zheng)形容(rong)易。(3)修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)速度(du)快,最快修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)量(liang)可(ke)(ke)達100mm3/min。(4)基(ji)材(cai)損(sun)傷小,發熱點(dian)小,修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)后焊(han)(han)(han)(han)(han)點(dian)手指可(ke)(ke)觸(chu)摸,不(bu)會造成(cheng)基(ji)材(cai)退火變(bian)形。(5)電(dian)壓適應(ying)(ying)范圍(wei)大,使(shi)用(yong)開關(guan)電(dian)源(yuan),當電(dian)壓變(bian)化在(zai)±20%的范圍(wei)內波動時,機(ji)(ji)(ji)器(qi)仍(reng)能保證正(zheng)常工作,并維持穩定(ding)(ding)的輸出(chu)功率(lv)。(6)攜(xie)帶(dai)方(fang)便(bian),整(zheng)機(ji)(ji)(ji)體積(ji)小,重量(liang)輕(qing),耗(hao)電(dian)省。2、冷(leng)焊(han)(han)(han)(han)(han)機(ji)(ji)(ji)的缺(que)點(dian):(1)冷(leng)焊(han)(han)(han)(han)(han)修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)后,焊(han)(han)(han)(han)(han)材(cai)與母體有一定(ding)(ding)的色差。(2)因為焊(han)(han)(han)(han)(han)材(cai)材(cai)質原(yuan)因,焊(han)(han)(han)(han)(han)補(bu)(bu)處有漏氣現象,所以不(bu)能應(ying)(ying)用(yong)于(yu)(yu)水泵、閥門(men)等(deng)(deng)(deng)貫穿性(xing)的孔(kong)洞(dong)修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)。(3)無法處理鋅、錫(xi)等(deng)(deng)(deng)熔(rong)點(dian)很低的材(cai)料(liao)和硬(ying)質合(he)(he)金,高反(fan)射(she)性(xing)及高導熱性(xing)材(cai)料(liao)如鋁(lv)、銅及其(qi)合(he)(he)金,焊(han)(han)(han)(han)(han)接性(xing)會受(shou)激光所改(gai)變(bian)。3、冷(leng)焊(han)(han)(han)(han)(han)機(ji)(ji)(ji)的用(yong)途:(1)模(mo)(mo)具(ju)制造行業(ye):塑料(liao)模(mo)(mo)表(biao)面的打毛、頭盔塑料(liao)模(mo)(mo)具(ju)分型面堆焊(han)(han)(han)(han)(han)修(xiu)(xiu)(xiu)(xiu)復(fu)、鋁(lv)合(he)(he)金壓鑄(zhu)模(mo)(mo)具(ju)分流(liu)錐表(biao)面強化等(deng)(deng)(deng)。(2)塑料(liao)橡(xiang)膠(jiao)工業(ye):橡(xiang)塑機(ji)(ji)(ji)械零部件(jian)修(xiu)(xiu)(xiu)(xiu)復(fu),橡(xiang)膠(jiao)、塑料(liao)件(jian)用(yong)的模(mo)(mo)具(ju)超差、磨(mo)損(sun)與修(xiu)(xiu)(xiu)(xiu)補(bu)(bu)。(3)汽(qi)車與機(ji)(ji)(ji)車的制造與維修(xiu)(xiu)(xiu)(xiu)行業(ye):用(yong)于(yu)(yu)凸輪、曲軸、活塞、汽(qi)缸、離合(he)(he)器(qi)、摩擦片、排氣閥等(deng)(deng)(deng)補(bu)(bu)差和修(xiu)(xiu)(xiu)(xiu)復(fu)。(4)鑄(zhu)造工業(ye)鐵(tie)、銅、鋁(lv)鑄(zhu)件(jian)砂眼氣孔(kong)等(deng)(deng)(deng)缺(que)陷的修(xiu)(xiu)(xiu)(xiu)補(bu)(bu),鋁(lv)模(mo)(mo)型磨(mo)損(sun)修(xiu)(xiu)(xiu)(xiu)復(fu)。
三、冷焊機的使用方法
1、將工(gong)件表面油污或者銹跡(ji)等清理干凈。2、開(kai)(kai)啟(qi)主機(ji)后面板(ban)的(de)(de)電(dian)(dian)源總開(kai)(kai)關,按下啟(qi)動鍵。3、根據實際工(gong)況,選擇焊(han)(han)(han)(han)接模式(shi)、脈(mo)沖(chong)電(dian)(dian)流和脈(mo)沖(chong)時(shi)間。4、打開(kai)(kai)氬氣瓶閥(fa)門(men)(men),調節氬氣節流閥(fa)。5、將焊(han)(han)(han)(han)槍(qiang)放(fang)(fang)于合適位置,踩(cai)腳(jiao)踏開(kai)(kai)關,即可(ke)(ke)產(chan)生(sheng)一(yi)個(ge)焊(han)(han)(han)(han)點。連續(xu)(xu)重復(fu)該動作可(ke)(ke)產(chan)生(sheng)一(yi)條具有(you)一(yi)定(ding)高度和寬(kuan)度的(de)(de)焊(han)(han)(han)(han)線。如果您操作很熟練,可(ke)(ke)將面板(ban)上的(de)(de)“連續(xu)(xu)/單點”按鍵選擇在“連續(xu)(xu)”狀態,踩(cai)住腳(jiao)踏開(kai)(kai)關不放(fang)(fang),此時(shi)設備連續(xu)(xu)輸出脈(mo)沖(chong),產(chan)生(sheng)連續(xu)(xu)的(de)(de)焊(han)(han)(han)(han)點。6、停止(zhi)工(gong)作時(shi)需關閉(bi)焊(han)(han)(han)(han)機(ji)電(dian)(dian)源,關閉(bi)氬氣瓶閥(fa)門(men)(men)。(焊(han)(han)(han)(han)機(ji)關閉(bi)后,設備面板(ban)上的(de)(de)顯示仍然會持(chi)續(xu)(xu)一(yi)段(duan)時(shi)間,直至余電(dian)(dian)放(fang)(fang)完。這是正常現象(xiang))
四、冷焊機價格多少錢一臺
冷焊機的型號有很多種的,而不同的型號焊出來的效果也不同,價格也不同,市面上的不銹鋼冷焊機,其價格大致可分為四個區間:1、1000-4000元區間(保證冷焊效果前提下,熔深0.3-0.8mm)。2、4000-10000元區間(保證冷焊效果前提下,熔深0.2-1.2mm)。3、10000-20000元區間(保證冷焊效果前提下,熔深0.08-1.6mm)。4、20000-50000元區間(保證冷焊效果前提下,熔深0.2-3.5mm),選擇的時候主要是根據焊接需求和實際應用情況選擇合適價位的產品,并注意考慮冷焊機品牌、焊補效率、電(dian)源、控(kong)制方(fang)式、抗干擾能力等方(fang)面(mian)。
選購冷焊機時千萬(wan)不(bu)要(yao)(yao)因為價(jia)格便宜(yi),而(er)盲目跟(gen)從購買,選擇(ze)比較有(you)(you)知名(ming)(ming)度的(de)(de)品(pin)(pin)牌(pai)(pai),不(bu)僅品(pin)(pin)質(zhi)有(you)(you)保證,售后服(fu)務也有(you)(you)保障。當然追求品(pin)(pin)牌(pai)(pai)的(de)(de)東西不(bu)一定(ding)就是追求價(jia)格的(de)(de)昂貴,不(bu)同(tong)的(de)(de)經濟水平我們可(ke)以選擇(ze)不(bu)同(tong)價(jia)位的(de)(de)名(ming)(ming)牌(pai)(pai)產(chan)品(pin)(pin)。選擇(ze)網購商品(pin)(pin)的(de)(de)朋友(you)要(yao)(yao)認(ren)準(zhun)品(pin)(pin)牌(pai)(pai)的(de)(de)旗艦(jian)店鋪,這樣子才能做到(dao)萬(wan)無一失(shi)。
