壓接鉗有哪些分類呢
1、分體式壓接鉗
分體式壓接鉗需要(yao)配相應(ying)的(de)泵浦,一般適合(he)電(dian)架空線路和地下(xia)電(dian)纜(lan)線路使用(yong)(yong);也有適合(he)大型電(dian)纜(lan)的(de)分體式壓(ya)(ya)接(jie)鉗(qian)。一機多用(yong)(yong),可用(yong)(yong)于鉗(qian)壓(ya)(ya)管鉗(qian)壓(ya)(ya),也可以實(shi)現六角壓(ya)(ya)模壓(ya)(ya)接(jie)。
2、充(chong)電式壓(ya)接鉗(qian)
充電式壓(ya)接鉗(qian)結(jie)構緊湊、重量輕,進、退操作(zuo)按鈕安(an)排合理。單手(shou)即可操作(zuo);采用低、
高壓(ya)(ya)(ya)兩級柱(zhu)塞泵驅動設計,壓(ya)(ya)(ya)接快速,系統設有(you)安全溢流閥(fa),標準(zhun)出力后自(zi)動卸壓(ya)(ya)(ya),頭部(bu)可作(zuo)350度旋轉,適合不同角度壓(ya)(ya)(ya)接;工具配(pei)有(you)背帶(dai),特別適合登高作(zuo)業(新型鋰電池BP-14LN可壓(ya)(ya)(ya)接90次);
配置:主機一(yi)(yi)臺(tai)、電池一(yi)(yi)塊(kuai)、充電器一(yi)(yi)個(ge)、樹脂(zhi)工具箱一(yi)(yi)個(ge)。
3、手動式壓接鉗
采用高(gao)、低兩級(ji)柱塞(sai)泵驅動設(she)計,操作快速省力;系統設(she)有安全溢流閥,標準出力后自動卸壓。
4、導線壓接鉗
導線(xian)(xian)壓(ya)接(jie)鉗(qian)是(shi)一種用(yong)冷壓(ya)的(de)(de)方法來連接(jie)銅、鋁(lv)(lv)導線(xian)(xian)的(de)(de)五金(jin)工(gong)具,特(te)別是(shi)在(zai)鋁(lv)(lv)絞(jiao)線(xian)(xian)和(he)鋼(gang)芯鋁(lv)(lv)絞(jiao)線(xian)(xian)敷(fu)設施工(gong)中(zhong)常要(yao)用(yong)到(dao)它。壓(ya)接(jie)鉗(qian)大(da)致可分為手壓(ya)和(he)油壓(ya)兩類。導線(xian)(xian)截面為35m㎡及(ji)以下用(yong)手壓(ya)鉗(qian),35m㎡以上用(yong)齒輪壓(ya)鉗(qian)或油壓(ya)鉗(qian)。隨著機(ji)械制造工(gong)業的(de)(de)發展,電工(gong)可采用(yong)的(de)(de)機(ji)械工(gong)具越(yue)來越(yue)多,使用(yong)這(zhe)些(xie)工(gong)具不僅(jin)能大(da)大(da)降低(di)勞動強(qiang)度(du),而且能成倍的(de)(de)提(ti)高工(gong)作效率,所以電工(gong)有必要(yao)了解、掌握這(zhe)些(xie)工(gong)具,要(yao)善于運用(yong)這(zhe)些(xie)先進工(gong)具。
壓接鉗銜接鋁芯的方法
(1)依據(ju)導線截面挑選(xuan)壓膜和橢圓形鋁套管;
(2)把銜接(jie)處(chu)的導線絕緣護套(tao)剝除(chu),剝除(chu)長度應為(wei)鋁套(tao)管長度通常加上5~10mm(裸鋁線無此此項),用鋼絲刷(shua)去芯線外表的氧化層(ceng)(膜);
(3)用另一清洗的鋼(gang)絲刷蘸一些凡士林鋅粉膏(gao)均勻(yun)地涂改在芯線上(shang),以防(fang)氧化(hua)層重生(sheng)。
(4)用圓(yuan)條形鋼絲刷鏟(chan)除鋁(lv)套管內(nei)(nei)壁的氧化層及油垢,最佳也在管子內(nei)(nei)壁涂(tu)上凡士林鋅粉膏。
(5)把兩根芯線相對(dui)地(di)刺進鋁(lv)套管,使兩個線頭恰好在鋁(lv)套管的正中(zhong)銜接。
(6)依據鋁套(tao)管(guan)的(de)粗細挑選恰當的(de)線模裝在(zai)壓(ya)接鉗上,擰緊定位螺絲后(hou),把(ba)套(tao)有鋁套(tao)管(guan)的(de)芯線嵌入(ru)線模。
(7)對準鋁(lv)(lv)套管(guan)(guan),用(yong)力捏夾(jia)鉗柄,進行壓(ya)接:先壓(ya)兩頭的(de)(de)兩個(ge)坑,再壓(ya)中(zhong)心的(de)(de)兩個(ge)坑,壓(ya)坑應(ying)在一向上。接頭壓(ya)接結束(shu)后(hou)要(yao)查(cha)看鋁(lv)(lv)套管(guan)(guan)彎曲度(du)不該大于管(guan)(guan)長的(de)(de)2%,不然要(yao)用(yong)木錘校(xiao)直(zhi);鋁(lv)(lv)套管(guan)(guan)不該有裂(lie)紋(wen);鋁(lv)(lv)套管(guan)(guan)外面的(de)(de)導線不得有“燈籠”形鼓(gu)包或“抽筋”形不齊等表象(xiang)。
(8)擦去剩余的油(you)膏,在鋁(lv)套管(guan)兩頭及(ji)合縫處涂(tu)刷一層快干的瀝青(qing)漆(qi)。然后再(zai)(zai)鋁(lv)套管(guan)及(ji)暴(bao)露導線有些先包兩層黃蠟帶,再(zai)(zai)包兩層黑膠布,一向抱(bao)到絕緣層20mm的當地
