中频点焊机电容器行业应用

      点(dian)焊(han)机系采用双面双点(dian)过流(liu)(liu)焊(han)接的(de)原理,工(gong)作时(shi)两个电(dian)(dian)极(ji)加压(ya)工(gong)件使两层金(jin)属在两电(dian)(dian)极(ji)的(de)压(ya)力下形成(cheng)一(yi)定的(de)接触(chu)(chu)电(dian)(dian)阻(zu),而焊(han)接电(dian)(dian)流(liu)(liu)从一(yi)电(dian)(dian)极(ji)流(liu)(liu)经另一(yi)电(dian)(dian)极(ji)时(shi)在两接触(chu)(chu)电(dian)(dian)阻(zu)点(dian)形成(cheng)瞬间的(de)热(re)熔接,且焊(han)接电(dian)(dian)流(liu)(liu)瞬间从另一(yi)电(dian)(dian)极(ji)沿两工(gong)件流(liu)(liu)至此电(dian)(dian)极(ji)形成(cheng)回路,并且不会伤(shang)及被(bei)焊(han)工(gong)件的(de)内(nei)部结构。

      使(shi)用方法:

1、焊接时(shi)应先(xian)调节(jie)电极杆的(de)位置(zhi),使(shi)电极刚好压到(dao)焊件时(shi),电极臂(bei)保持互相平(ping)行。

2、电(dian)流调节(jie)开(kai)关级数的(de)选择可按焊件厚度与材质而选定。通电(dian)后电(dian)源指示灯应亮,电(dian)极压(ya)(ya)力(li)大(da)小(xiao)可调整弹(dan)簧压(ya)(ya)力(li)螺母,改变其压(ya)(ya)缩程度而获得。

3、在(zai)完成上述调整后,可先接(jie)(jie)(jie)通冷却水后再(zai)接(jie)(jie)(jie)通电(dian)(dian)(dian)(dian)源(yuan)准备焊接(jie)(jie)(jie)。焊接(jie)(jie)(jie)过程的程序:焊件(jian)置于两(liang)电(dian)(dian)(dian)(dian)极(ji)之间,踩下(xia)脚踏板(ban),并使上电(dian)(dian)(dian)(dian)极(ji)与(yu)焊件(jian)接(jie)(jie)(jie)触(chu)并加压,在(zai)继续压下(xia)脚踏板(ban)时,电(dian)(dian)(dian)(dian)源(yuan)触(chu)头开关接(jie)(jie)(jie)通,于是变压器开始(shi)工作(zuo)次级(ji)回路通电(dian)(dian)(dian)(dian)使焊件(jian)加热(re)。当焊接(jie)(jie)(jie)一定时间后松开脚踏板(ban)时电(dian)(dian)(dian)(dian)极(ji)上升(sheng),借(jie)弹(dan)簧的拉(la)力先切断电(dian)(dian)(dian)(dian)源(yuan)而后恢(hui)复原状,单点焊接(jie)(jie)(jie)过程即告结束(shu)。
