UN Series Flash Butt Welding Machine UN系列闪光对焊机 闪光对焊的主要焊接工艺及原理: 1.焊接电极加紧工件,在工件尚未完全接触时,开始闪光。 2.接下来,焊接电极夹紧的工件缓慢接近,随着电流密度的增加,工件间接触处开始熔化,同时有部分金属熔液溢出,形成初始的对焊节点。 3.焊接区域变得越来越热,对焊的速度也随着加速。 4.闪光和飞溅使两个接触面完全焊接在一起。 5.最后再利用高压进行**锻,切断电流,焊接完成。 The Main Principle of Flash Butt Welding: 1.The flash butt process starts when the two workpieces to be welded which are clamped by welding jams still not meet each other. 2.During the subsequence,move the welding jaws together slowly,the welding current density will increase,then the metal material in the gap between the jaws becomes molten,at the same time a shower of sparks also being emitted. 3.As the cross-sectional area in the welding becomes extremely hot,the motion is accelerated. 4.The flashing also makes the surfaces to welded together totally. 5.Finally the upset occurs at high pressure,the welding current is cut off. 主要应用领域: 1.各种餐具,厨房和餐具刀具的焊接; 2.自行车,摩托车,汽车车圈,及其他金属环的对焊; 3.各种金属丝,金属带,铁棒,建筑用钢筋对焊; 4.各种圆管,方管的“L”形与“T”形焊接; 5.窗框与门框的对角焊接。 Typical Applications: 1.All kinds of dinnerware,cooking knives and table knives; 2.Bicycle rim,motorbike rim,car rim,or similar strip rings; 3.Various metal wire and steel strip,construction steel bar and rebar; 4.Round,Square and Rectangular tubes welding into “L” or “T” shape; 5.Mitre welding of door and window frames. 主要技术参数: Main Technical Parameter: 参数 Parameter 额度功率Rated Power 额度电压Rated Voltage 额定频率Rated Frequency 较大短路电流Max Short Current 负载持续率Rated Duty Cycle 较大加紧力Max Clamping Force 较大**锻力 Max Upsetting Force 冷却水流量Cooling Water Required 平均重量Average Weight 外形尺寸Over Dimensions L*W*H 型号 Model No. UN-50 50KVA 380V/420V 50/60Hz 19000A 50% 4000N 2000N 150L/H 350Kg 100*90*150CM UN-75 75KVA 380V/420V 50/60Hz 24000A 50% 6500N 3000N 150L/H 450Kg 100*90*150CM UN-100 100KVA 380V/420V 50/60Hz 28000A 50% 6500N 3000N 150L/H 550Kg 100*90*150CM UN-150 150KVA 380V/420V 50/60Hz 32000A 50% 8500N 4000N 300L/H 1200Kg 140*100*170CM UN-200 200KVA 380V/420V 50/60Hz 37000A 50% 8500N 4000N 300L/H 1400Kg 140*100*170CM UN-250 250KVA 380V/420V 50/60Hz 45000A 50% 12000N 6000N 600L/H 1600Kg 180*120*190CM UN-300 300KVA 380V/420V 50/60Hz 52000A 50% 12000N 6000N 600L/H 1800Kd 180*120*190CM
