【電工刀(dao)】電工刀(dao)使用(yong)注意事項 電工刀(dao)的用(yong)途有哪些(xie)
電工刀是電(dian)工常(chang)用的(de)一(yi)(yi)種切削工具。普(pu)通的(de)電(dian)工刀(dao)(dao)(dao)由刀(dao)(dao)(dao)片(pian)(pian)、刀(dao)(dao)(dao)刃(ren)、刀(dao)(dao)(dao)把(ba)、刀(dao)(dao)(dao)掛(gua)等構(gou)成。不用時,把(ba)刀(dao)(dao)(dao)片(pian)(pian)收縮(suo)到(dao)刀(dao)(dao)(dao)把(ba)內。刀(dao)(dao)(dao)片(pian)(pian)根部(bu)與刀(dao)(dao)(dao)柄(bing)相(xiang)鉸接,其(qi)上帶有刻度(du)線(xian)及刻度(du)標識,前端(duan)(duan)形成有螺絲刀(dao)(dao)(dao)刀(dao)(dao)(dao)頭,兩面加工有銼(cuo)刀(dao)(dao)(dao)面區域,刀(dao)(dao)(dao)刃(ren)上具有一(yi)(yi)段內凹形彎(wan)刀(dao)(dao)(dao)口(kou)(kou),彎(wan)刀(dao)(dao)(dao)口(kou)(kou)末端(duan)(duan)形成刀(dao)(dao)(dao)口(kou)(kou)尖,刀(dao)(dao)(dao)柄(bing)上設有防止刀(dao)(dao)(dao)片(pian)(pian)退彈(dan)的(de)保護(hu)鈕(niu)。電(dian)工刀(dao)(dao)(dao)的(de)刀(dao)(dao)(dao)片(pian)(pian)匯集有多(duo)項功能,使(shi)用時只需一(yi)(yi)把(ba)電(dian)工刀(dao)(dao)(dao)便(bian)可完成連接導線(xian)的(de)各項操作,無需攜帶其(qi)它工具,具有結構(gou)簡單、使(shi)用方便(bian)、功能多(duo)樣(yang)等有益(yi)效果。
電工刀使用注意事項
電工刀在電(dian)工安裝(zhuang)維修中用(yong)于切削導線(xian)的絕緣(yuan)層、電(dian)纜(lan)絕緣(yuan)、木槽板(ban)等(deng),規格有大號(hao)、小(xiao)(xiao)號(hao)之(zhi)分(fen)。六(liu)號(hao)刀片(pian)長112毫(hao)米(mi);小(xiao)(xiao)號(hao)刀片(pian)長88毫(hao)米(mi)。有的電(dian)工刀上帶(dai)(dai)有鋸(ju)片(pian)和(he)錐子,可用(yong)來(lai)鋸(ju)小(xiao)(xiao)木片(pian)和(he)錐孔。電(dian)工刀沒有絕緣(yuan)保護,禁止帶(dai)(dai)電(dian)作業。使用(yong)電(dian)工刀,應避免切割堅硬的材料,以保護刀口。刀口用(yong)鈍后,可用(yong)油石磨。如果刀刃(ren)部分(fen)損壞較重,可用(yong)砂輪磨,但須(xu)防止退火。
電工刀的用途有哪些
1、多(duo)功能電(dian)工刀的鋸(ju)片,可(ke)用(yong)來鋸(ju)割木條(tiao)、竹(zhu)條(tiao),制(zhi)作(zuo)木榫、竹(zhu)榫。多(duo)功能電(dian)工刀除(chu)了刀片外,還有鋸(ju)片、錐(zhui)子(zi)、擴孔(kong)錐(zhui)等。
2、在硬雜木上(shang)擰螺絲很(hen)費勁時,可先用多功能電(dian)工(gong)刀上(shang)的錐子錐個洞,這時擰螺絲便(bian)省(sheng)力多了。
3、圓木上需要鉆(zhan)穿線孔(kong),可先用(yong)錐子鉆(zhan)出(chu)小孔(kong),然后(hou)用(yong)擴(kuo)孔(kong)錐將小孔(kong)擴(kuo)大,以利較粗(cu)的電線穿過,這是又(you)一種多(duo)功能電工刀。
4、多功能電工刀除了刀片以(yi)外,有(you)的還帶有(you)尺子、鋸(ju)子、剪子和(he)開(kai)(kai)啤酒瓶蓋(gai)的開(kai)(kai)瓶扳手等工具。
5、電線、電纜的(de)接頭處常(chang)使用(yong)(yong)塑料或橡皮帶等作加強絕緣(yuan),這種絕緣(yuan)材(cai)料可用(yong)(yong)多功(gong)能(neng)電工刀的(de)剪(jian)子將其剪(jian)斷。
6、電工刀上的鋼尺,可用來檢(jian)測電器(qi)尺寸。
7、用電(dian)工(gong)刀(dao)(dao)剖削(xue)(xue)(xue)電(dian)線(xian)(xian)(xian)(xian)絕(jue)(jue)緣(yuan)層時,可把刀(dao)(dao)略微翹(qiao)起一些,用刀(dao)(dao)刃(ren)的圓角抵(di)住線(xian)(xian)(xian)(xian)芯。切(qie)忌把刀(dao)(dao)刃(ren)垂直對著導(dao)線(xian)(xian)(xian)(xian)切(qie)割絕(jue)(jue)緣(yuan)層,因為這樣容易割傷電(dian)線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)芯。導(dao)線(xian)(xian)(xian)(xian)接頭之前應把導(dao)線(xian)(xian)(xian)(xian)上的絕(jue)(jue)緣(yuan)剝(bo)(bo)除。用電(dian)工(gong)刀(dao)(dao)切(qie)剝(bo)(bo)時,刀(dao)(dao)口千(qian)萬別傷著芯線(xian)(xian)(xian)(xian)。常用的剝(bo)(bo)削(xue)(xue)(xue)方(fang)法有(you)級段(duan)剝(bo)(bo)落和斜削(xue)(xue)(xue)法剝(bo)(bo)削(xue)(xue)(xue),電(dian)工(gong)刀(dao)(dao)的刀(dao)(dao)刃(ren)部分要磨(mo)得鋒利才好剝(bo)(bo)削(xue)(xue)(xue)電(dian)線(xian)(xian)(xian)(xian)。但不可太(tai)鋒利,太(tai)鋒利容易削(xue)(xue)(xue)傷線(xian)(xian)(xian)(xian)芯,磨(mo)得太(tai)鈍,則無法剝(bo)(bo)削(xue)(xue)(xue)絕(jue)(jue)緣(yuan)層。
8、圓木(mu)與木(mu)槽板或塑料槽板的吻接(jie)凹槽,就可(ke)采用電工刀在施工現(xian)場(chang)切削。通常用左手(shou)托(tuo)住圓木(mu),右手(shou)持刀切削。
9、利用電工刀同時(shi)還可以削(xue)制木(mu)榫、竹(zhu)榫等。
