UN Series Flash Butt Welding Machine UN系列閃光對(duì)焊機(jī) 整機(jī)特性： 將對(duì)接的工件，自動(dòng)夾緊，再通過(guò)氣液控制，先通電緩慢推動(dòng)將工件焊接處表面的氧化和凸起不平處閃光去掉后讓焊接的工件端面熱塑化，焊接區(qū)域變得越來(lái)越熱，對(duì)焊的速度也隨著加速，閃光和飛濺使兩個(gè)接觸面完全焊接在一起，.最后再迅速加壓頂鍛使焊接兩端面熔接，切斷電流，焊接完成。這種焊接強(qiáng)度高，致密性好，無(wú)假焊，無(wú)夾渣，無(wú)氣孔. 主要應(yīng)用領(lǐng)域： 1.各種餐具，的焊接; 2.自行車，摩托車，汽車車圈，及其他金屬環(huán)的對(duì)焊; 3.各種金屬帶，鐵棒，建筑用鋼筋，圓管，方管對(duì)焊； Main Features: Clamp the welding parts by welding elerode firstly without touch, then driving the welding elerode slowly together with a preheat current to flash clean the oxidation.uneven surface to make welding area as hot plasticizing. The temperature of welding area turn to more.more heat.the welding current density increasing together, flash.splash make two touch surface has melted together. Finally perform a fast upsetting force on welding joint to finish welding.breaking current. This type welding joint has high strength without false welding.pores. Main Applications: 1.All kinds of dinnerware,knives ; 2.Bicycle rim,motorbike rim,car rim,or similar strip rings; 3.Various steel strip,steel rod, construion rebar,round tube.square tube ; 主要技術(shù)參數(shù)： Main Technical Parameters: 參數(shù) Parameter 額度功率Rated Power 額定電壓Rated Voltage 額定頻率Rated Frequency 最大短路電流Max Short Current 負(fù)載持續(xù)率Rated Duty Cycle 最大加緊力Max Clamping Force 最大頂鍛力 Max Upsetting Force 冷卻水流量Cooling Water Required 平均重量Average Weight 外形尺寸Over Dimensions L*W*H 型號(hào) Model No. UN-50 50KVA 380V 50/60Hz 19000A 50% 4000N 2000N 150L/H 350Kg 100*90*150CM UN-75 75KVA 380V 50/60Hz 24000A 50% 6500N 3000N 150L/H 450Kg 100*90*150CM UN-100 100KVA 380V 50/60Hz 28000A 50% 6500N 3000N 150L/H 550Kg 100*90*150CM UN-150 150KVA 380V 50/60Hz 32000A 50% 8500N 4000N 300L/H 1200Kg 140*100*170CM UN-200 200KVA 380V 50/60Hz 37000A 50% 8500N 4000N 300L/H 1400Kg 140*100*170CM UN-250 250KVA 380V 50/60Hz 45000A 50% 12000N 6000N 600L/H 1600Kg 180*120*190CM UN-300 300KVA 380V 50/60Hz 52000A 50% 12000N 6000N 600L/H 1800Kg 180*120*190CM
