【電工(gong)刀(dao)】電工(gong)刀(dao)使用注意(yi)事項 電工(gong)刀(dao)的用途有哪些(xie)
電工刀是電(dian)工(gong)(gong)(gong)常用的一種(zhong)切(qie)削工(gong)(gong)(gong)具。普通的電(dian)工(gong)(gong)(gong)刀(dao)(dao)(dao)由刀(dao)(dao)(dao)片(pian)(pian)(pian)、刀(dao)(dao)(dao)刃(ren)、刀(dao)(dao)(dao)把、刀(dao)(dao)(dao)掛等構(gou)成(cheng)。不用時(shi),把刀(dao)(dao)(dao)片(pian)(pian)(pian)收縮到(dao)刀(dao)(dao)(dao)把內(nei)。刀(dao)(dao)(dao)片(pian)(pian)(pian)根部與刀(dao)(dao)(dao)柄相(xiang)鉸接,其(qi)上帶有(you)刻度(du)線(xian)及刻度(du)標(biao)識,前端(duan)形(xing)成(cheng)有(you)螺絲刀(dao)(dao)(dao)刀(dao)(dao)(dao)頭,兩面加(jia)工(gong)(gong)(gong)有(you)銼刀(dao)(dao)(dao)面區域(yu),刀(dao)(dao)(dao)刃(ren)上具有(you)一段(duan)內(nei)凹形(xing)彎刀(dao)(dao)(dao)口(kou)(kou),彎刀(dao)(dao)(dao)口(kou)(kou)末(mo)端(duan)形(xing)成(cheng)刀(dao)(dao)(dao)口(kou)(kou)尖,刀(dao)(dao)(dao)柄上設(she)有(you)防止刀(dao)(dao)(dao)片(pian)(pian)(pian)退彈(dan)的保(bao)護鈕。電(dian)工(gong)(gong)(gong)刀(dao)(dao)(dao)的刀(dao)(dao)(dao)片(pian)(pian)(pian)匯集有(you)多(duo)項功(gong)能,使用時(shi)只需(xu)一把電(dian)工(gong)(gong)(gong)刀(dao)(dao)(dao)便可完成(cheng)連(lian)接導(dao)線(xian)的各項操作,無需(xu)攜(xie)帶其(qi)它工(gong)(gong)(gong)具,具有(you)結構(gou)簡單、使用方(fang)便、功(gong)能多(duo)樣等有(you)益效果。
電工刀使用注意事項
電工刀在電工(gong)安裝(zhuang)維修中(zhong)用(yong)(yong)于切(qie)削導線的絕(jue)緣層、電纜絕(jue)緣、木(mu)槽板等,規格有(you)大號、小(xiao)號之分(fen)(fen)。六號刀(dao)片長112毫(hao)米;小(xiao)號刀(dao)片長88毫(hao)米。有(you)的電工(gong)刀(dao)上帶有(you)鋸片和(he)錐(zhui)子,可(ke)(ke)用(yong)(yong)來(lai)鋸小(xiao)木(mu)片和(he)錐(zhui)孔。電工(gong)刀(dao)沒有(you)絕(jue)緣保(bao)護(hu),禁止帶電作業(ye)。使(shi)用(yong)(yong)電工(gong)刀(dao),應避(bi)免切(qie)割堅硬的材料,以保(bao)護(hu)刀(dao)口。刀(dao)口用(yong)(yong)鈍后,可(ke)(ke)用(yong)(yong)油石磨(mo)。如果刀(dao)刃部分(fen)(fen)損壞較重,可(ke)(ke)用(yong)(yong)砂輪磨(mo),但須(xu)防(fang)止退火。
電工刀的用途有哪些
1、多功能電工刀(dao)的(de)鋸(ju)片,可用來鋸(ju)割(ge)木條(tiao)、竹條(tiao),制作木榫、竹榫。多功能電工刀(dao)除了(le)刀(dao)片外,還有鋸(ju)片、錐子、擴孔錐等。
2、在硬雜木上擰螺絲很(hen)費勁時,可先(xian)用(yong)多功能(neng)電工(gong)刀上的錐子錐個洞,這時擰螺絲便省力多了。
3、圓木上需要鉆穿線(xian)孔,可先用錐(zhui)(zhui)子鉆出小孔,然后用擴孔錐(zhui)(zhui)將小孔擴大,以利較粗的電(dian)線(xian)穿過,這是又一(yi)種多功(gong)能(neng)電(dian)工刀。
4、多功能電工(gong)刀(dao)除了(le)刀(dao)片(pian)以外,有(you)的(de)(de)還(huan)帶有(you)尺子、鋸子、剪子和開(kai)啤酒瓶蓋的(de)(de)開(kai)瓶扳手等工(gong)具。
5、電(dian)(dian)線、電(dian)(dian)纜的接頭處(chu)常使用(yong)塑料(liao)或(huo)橡皮帶等作加(jia)強絕緣(yuan),這(zhe)種絕緣(yuan)材料(liao)可用(yong)多功能電(dian)(dian)工(gong)刀的剪子將其剪斷。
6、電工刀上的鋼尺,可用(yong)來(lai)檢測電器尺寸。
7、用(yong)電工(gong)刀剖(pou)削(xue)電線絕(jue)緣(yuan)(yuan)層(ceng)時(shi),可把(ba)(ba)刀略微(wei)翹起一些,用(yong)刀刃(ren)的(de)圓角抵(di)住線芯(xin)。切忌(ji)把(ba)(ba)刀刃(ren)垂(chui)直(zhi)對著(zhu)導(dao)線切割絕(jue)緣(yuan)(yuan)層(ceng),因為這樣容易(yi)割傷(shang)(shang)電線線芯(xin)。導(dao)線接頭之前(qian)應把(ba)(ba)導(dao)線上的(de)絕(jue)緣(yuan)(yuan)剝(bo)(bo)除。用(yong)電工(gong)刀切剝(bo)(bo)時(shi),刀口千萬別傷(shang)(shang)著(zhu)芯(xin)線。常用(yong)的(de)剝(bo)(bo)削(xue)方法(fa)有級段剝(bo)(bo)落和斜(xie)削(xue)法(fa)剝(bo)(bo)削(xue),電工(gong)刀的(de)刀刃(ren)部分要磨得鋒利(li)才好剝(bo)(bo)削(xue)電線。但不可太鋒利(li),太鋒利(li)容易(yi)削(xue)傷(shang)(shang)線芯(xin),磨得太鈍,則(ze)無法(fa)剝(bo)(bo)削(xue)絕(jue)緣(yuan)(yuan)層(ceng)。
8、圓(yuan)木與木槽(cao)板(ban)或(huo)塑料槽(cao)板(ban)的吻接凹槽(cao),就可采用電工刀在施工現場(chang)切(qie)削(xue)。通常用左手托住圓(yuan)木,右手持刀切(qie)削(xue)。
9、利用電工刀同時還可(ke)以削制木(mu)榫、竹榫等(deng)。
