精密点焊机线圈行业应用

      点焊(han)机系采用双面双点过流(liu)焊(han)接(jie)的(de)(de)原理,工作时(shi)两(liang)(liang)个电(dian)(dian)极加压(ya)工件使两(liang)(liang)层金属在(zai)两(liang)(liang)电(dian)(dian)极的(de)(de)压(ya)力下形成一定的(de)(de)接(jie)触电(dian)(dian)阻,而(er)焊(han)接(jie)电(dian)(dian)流(liu)从一电(dian)(dian)极流(liu)经(jing)另一电(dian)(dian)极时(shi)在(zai)两(liang)(liang)接(jie)触电(dian)(dian)阻点形成瞬间的(de)(de)热熔接(jie),且焊(han)接(jie)电(dian)(dian)流(liu)瞬间从另一电(dian)(dian)极沿两(liang)(liang)工件流(liu)至(zhi)此电(dian)(dian)极形成回路,并且不(bu)会(hui)伤及(ji)被焊工件(jian)的内部结构。

      使用方法:

1、焊接(jie)时应先调节电极(ji)(ji)杆的位置(zhi),使电极(ji)(ji)刚好压到焊件时,电极(ji)(ji)臂保持互相平行。

2、电流(liu)调节开关级数的选择可按焊件厚度(du)与(yu)材质而(er)选定。通电后电源指示灯应亮,电极压(ya)力大小(xiao)可调整弹簧压(ya)力螺母,改变其压(ya)缩程度(du)而(er)获得。

3、在完(wan)成上述(shu)调整后,可(ke)先(xian)接(jie)(jie)(jie)通冷(leng)却水(shui)后再(zai)接(jie)(jie)(jie)通电(dian)(dian)(dian)源(yuan)准备焊接(jie)(jie)(jie)。焊接(jie)(jie)(jie)过程(cheng)的(de)(de)程(cheng)序:焊件(jian)置于(yu)两电(dian)(dian)(dian)极(ji)之间(jian),踩(cai)下脚踏(ta)板,并使上电(dian)(dian)(dian)极(ji)与(yu)焊件(jian)接(jie)(jie)(jie)触并加压,在继(ji)续压下脚踏(ta)板时(shi)(shi),电(dian)(dian)(dian)源(yuan)触头开(kai)关接(jie)(jie)(jie)通,于(yu)是变压器(qi)开(kai)始(shi)工作次级回路通电(dian)(dian)(dian)使焊件(jian)加热。当焊接(jie)(jie)(jie)一定时(shi)(shi)间(jian)后松开(kai)脚踏(ta)板时(shi)(shi)电(dian)(dian)(dian)极(ji)上升,借(jie)弹簧的(de)(de)拉力(li)先(xian)切断电(dian)(dian)(dian)源(yuan)而后恢复(fu)原状,单点焊接(jie)(jie)(jie)过程(cheng)即告结束(shu)。
