壓接鉗有哪些分類呢
1、分體式壓接鉗
分體式壓接鉗需要配相應的(de)泵浦,一般(ban)適合(he)電(dian)架空線(xian)路和地下電(dian)纜(lan)線(xian)路使(shi)用(yong);也有適合(he)大型電(dian)纜(lan)的(de)分體式壓(ya)(ya)接鉗(qian)。一機多用(yong),可用(yong)于鉗(qian)壓(ya)(ya)管(guan)鉗(qian)壓(ya)(ya),也可以實現六角壓(ya)(ya)模壓(ya)(ya)接。
2、充電(dian)式(shi)壓接鉗(qian)
充(chong)電式壓接(jie)鉗結構緊湊、重(zhong)量輕,進、退操作按鈕安(an)排合理。單手即可操作;采(cai)用低、
高壓兩級柱(zhu)塞泵(beng)驅(qu)動(dong)設計(ji),壓接(jie)快速,系統設有安全溢流閥,標準出力后自動(dong)卸壓,頭部可(ke)作(zuo)350度(du)旋轉,適合不(bu)同角(jiao)度(du)壓接(jie);工具配有背帶,特別適合登(deng)高作(zuo)業(新型鋰電池BP-14LN可(ke)壓接(jie)90次);
配置:主(zhu)機一臺、電(dian)池一塊、充電(dian)器一個、樹脂工具箱一個。
3、手動式壓接鉗
采用(yong)高、低兩(liang)級柱塞泵驅動設(she)計,操作(zuo)快(kuai)速省(sheng)力;系統設(she)有(you)安全溢流閥(fa),標準(zhun)出力后自動卸(xie)壓。
4、導線壓接鉗
導線(xian)(xian)(xian)(xian)壓(ya)(ya)(ya)接(jie)鉗是(shi)一種(zhong)用冷壓(ya)(ya)(ya)的(de)方(fang)法來連接(jie)銅、鋁(lv)導線(xian)(xian)(xian)(xian)的(de)五金工(gong)(gong)具(ju),特別是(shi)在鋁(lv)絞線(xian)(xian)(xian)(xian)和鋼芯鋁(lv)絞線(xian)(xian)(xian)(xian)敷(fu)設施工(gong)(gong)中常要用到它。壓(ya)(ya)(ya)接(jie)鉗大(da)致(zhi)可(ke)分為手壓(ya)(ya)(ya)和油壓(ya)(ya)(ya)兩類。導線(xian)(xian)(xian)(xian)截面為35m㎡及(ji)以(yi)下用手壓(ya)(ya)(ya)鉗,35m㎡以(yi)上用齒輪壓(ya)(ya)(ya)鉗或油壓(ya)(ya)(ya)鉗。隨著機械制造工(gong)(gong)業的(de)發展,電工(gong)(gong)可(ke)采用的(de)機械工(gong)(gong)具(ju)越來越多,使(shi)用這些(xie)工(gong)(gong)具(ju)不僅(jin)能(neng)大(da)大(da)降(jiang)低勞動強度,而(er)且能(neng)成倍(bei)的(de)提高工(gong)(gong)作(zuo)效率(lv),所以(yi)電工(gong)(gong)有必要了解(jie)、掌握這些(xie)工(gong)(gong)具(ju),要善于運用這些(xie)先進(jin)工(gong)(gong)具(ju)。
壓接鉗銜接鋁芯的方法
(1)依(yi)據導線(xian)截面(mian)挑選壓膜和橢圓形鋁套管;
(2)把銜接處的(de)導線(xian)絕緣護套剝除,剝除長(chang)度應為鋁套管長(chang)度通常加上5~10mm(裸鋁線(xian)無此(ci)(ci)此(ci)(ci)項(xiang)),用鋼絲刷(shua)去芯線(xian)外表的(de)氧(yang)化層(ceng)(膜(mo));
(3)用另一(yi)清洗的(de)鋼絲(si)刷蘸一(yi)些凡士林鋅(xin)粉膏均勻地涂改在(zai)芯(xin)線上,以防氧化層(ceng)重生(sheng)。
(4)用圓條(tiao)形(xing)鋼絲(si)刷鏟除鋁套管內壁的氧化層及油垢,最(zui)佳也在(zai)管子內壁涂上凡(fan)士林鋅粉膏。
(5)把(ba)兩(liang)根芯線(xian)(xian)相對地刺進(jin)鋁(lv)套管,使兩(liang)個線(xian)(xian)頭恰好在鋁(lv)套管的(de)正中銜接。
(6)依據(ju)鋁套管的粗(cu)細挑選恰當(dang)的線模(mo)裝在壓(ya)接鉗上,擰緊定位螺絲后(hou),把套有(you)鋁套管的芯(xin)線嵌(qian)入(ru)線模(mo)。
(7)對準鋁套(tao)(tao)管(guan)(guan),用(yong)力捏夾鉗(qian)柄,進行壓(ya)(ya)接:先(xian)壓(ya)(ya)兩(liang)(liang)頭(tou)的兩(liang)(liang)個(ge)坑,再壓(ya)(ya)中(zhong)心的兩(liang)(liang)個(ge)坑,壓(ya)(ya)坑應(ying)在一(yi)向上。接頭(tou)壓(ya)(ya)接結束后要查(cha)看鋁套(tao)(tao)管(guan)(guan)彎曲(qu)度(du)不(bu)該大(da)于(yu)管(guan)(guan)長(chang)的2%,不(bu)然要用(yong)木錘校直;鋁套(tao)(tao)管(guan)(guan)不(bu)該有(you)裂紋(wen);鋁套(tao)(tao)管(guan)(guan)外(wai)面(mian)的導線不(bu)得有(you)“燈(deng)籠”形鼓包或“抽筋”形不(bu)齊等表象(xiang)。
(8)擦去剩余的油膏,在鋁(lv)套管(guan)兩(liang)(liang)頭(tou)及合縫處涂(tu)刷(shua)一(yi)層快干的瀝(li)青漆。然后(hou)再鋁(lv)套管(guan)及暴露(lu)導線有些先包兩(liang)(liang)層黃蠟帶,再包兩(liang)(liang)層黑膠布(bu),一(yi)向抱到絕緣(yuan)層20mm的當地
