【電工刀(dao)】電工刀(dao)使用注意事項 電工刀(dao)的用途有哪些

電工刀是電(dian)工(gong)常用(yong)的一種切削工(gong)具(ju)。普通(tong)的電(dian)工(gong)刀(dao)(dao)(dao)(dao)(dao)由刀(dao)(dao)(dao)(dao)(dao)片、刀(dao)(dao)(dao)(dao)(dao)刃、刀(dao)(dao)(dao)(dao)(dao)把(ba)(ba)、刀(dao)(dao)(dao)(dao)(dao)掛等構成。不用(yong)時，把(ba)(ba)刀(dao)(dao)(dao)(dao)(dao)片收縮到刀(dao)(dao)(dao)(dao)(dao)把(ba)(ba)內。刀(dao)(dao)(dao)(dao)(dao)片根部與刀(dao)(dao)(dao)(dao)(dao)柄相鉸接，其上(shang)帶有(you)(you)刻度線及刻度標識，前(qian)端(duan)形成有(you)(you)螺(luo)絲刀(dao)(dao)(dao)(dao)(dao)刀(dao)(dao)(dao)(dao)(dao)頭，兩面加工(gong)有(you)(you)銼刀(dao)(dao)(dao)(dao)(dao)面區域(yu)，刀(dao)(dao)(dao)(dao)(dao)刃上(shang)具(ju)有(you)(you)一段內凹(ao)形彎刀(dao)(dao)(dao)(dao)(dao)口(kou)，彎刀(dao)(dao)(dao)(dao)(dao)口(kou)末(mo)端(duan)形成刀(dao)(dao)(dao)(dao)(dao)口(kou)尖，刀(dao)(dao)(dao)(dao)(dao)柄上(shang)設有(you)(you)防(fang)止刀(dao)(dao)(dao)(dao)(dao)片退彈(dan)的保護(hu)鈕。電(dian)工(gong)刀(dao)(dao)(dao)(dao)(dao)的刀(dao)(dao)(dao)(dao)(dao)片匯(hui)集有(you)(you)多項(xiang)功能，使用(yong)時只需(xu)(xu)一把(ba)(ba)電(dian)工(gong)刀(dao)(dao)(dao)(dao)(dao)便可完成連接導線的各(ge)項(xiang)操作，無需(xu)(xu)攜(xie)帶其它工(gong)具(ju)，具(ju)有(you)(you)結構簡單(dan)、使用(yong)方便、功能多樣等有(you)(you)益效(xiao)果。

電工刀使用注意事項

電工刀在電(dian)(dian)工安(an)裝維修中(zhong)用(yong)(yong)(yong)于切(qie)削(xue)導線的絕緣(yuan)層、電(dian)(dian)纜絕緣(yuan)、木(mu)槽板(ban)等，規格有大號、小(xiao)號之(zhi)分。六號刀片(pian)長(chang)112毫米；小(xiao)號刀片(pian)長(chang)88毫米。有的電(dian)(dian)工刀上(shang)帶(dai)有鋸片(pian)和(he)錐(zhui)子，可(ke)用(yong)(yong)(yong)來鋸小(xiao)木(mu)片(pian)和(he)錐(zhui)孔(kong)。電(dian)(dian)工刀沒有絕緣(yuan)保(bao)護(hu)，禁止(zhi)帶(dai)電(dian)(dian)作業。使用(yong)(yong)(yong)電(dian)(dian)工刀，應避(bi)免切(qie)割堅硬的材料(liao)，以保(bao)護(hu)刀口。刀口用(yong)(yong)(yong)鈍(dun)后(hou)，可(ke)用(yong)(yong)(yong)油石磨(mo)。如果刀刃(ren)部分損壞較重，可(ke)用(yong)(yong)(yong)砂(sha)輪磨(mo)，但須防(fang)止(zhi)退火(huo)。

電工刀的用途有哪些

1、多功能電工(gong)刀(dao)的(de)鋸(ju)片(pian),可用(yong)來鋸(ju)割(ge)木條、竹條,制作木榫、竹榫。多功能電工(gong)刀(dao)除了刀(dao)片(pian)外(wai)，還(huan)有鋸(ju)片(pian)、錐子、擴孔(kong)錐等(deng)。

2、在硬雜木(mu)上擰(ning)螺(luo)絲很費勁(jing)時，可先(xian)用多功能電(dian)工刀上的錐(zhui)子錐(zhui)個洞(dong)，這時擰(ning)螺(luo)絲便省力多了(le)。

3、圓木上需要鉆(zhan)(zhan)穿(chuan)線孔，可先用(yong)錐子鉆(zhan)(zhan)出小孔，然后用(yong)擴孔錐將小孔擴大(da)，以利(li)較粗(cu)的電(dian)(dian)線穿(chuan)過，這是又(you)一種(zhong)多(duo)功能電(dian)(dian)工(gong)刀(dao)。

4、多功(gong)能電工刀除(chu)了刀片以外(wai)，有(you)的還(huan)帶有(you)尺(chi)子(zi)、鋸子(zi)、剪(jian)子(zi)和(he)開(kai)(kai)啤酒瓶蓋的開(kai)(kai)瓶扳手等工具。

5、電線(xian)、電纜的接頭處常使用塑(su)料或橡皮(pi)帶等作加強(qiang)絕緣(yuan)，這種絕緣(yuan)材料可用多功能電工刀的剪子將(jiang)其剪斷。

6、電工刀上(shang)的鋼尺，可用來檢測電器尺寸(cun)。

7、用電(dian)(dian)工(gong)刀(dao)(dao)剖削(xue)(xue)電(dian)(dian)線(xian)絕(jue)緣(yuan)層時,可把刀(dao)(dao)略微翹起一些(xie),用刀(dao)(dao)刃的(de)(de)圓角(jiao)抵(di)住(zhu)線(xian)芯(xin)。切(qie)忌把刀(dao)(dao)刃垂直對著(zhu)導線(xian)切(qie)割絕(jue)緣(yuan)層,因為這樣容(rong)易割傷(shang)電(dian)(dian)線(xian)線(xian)芯(xin)。導線(xian)接(jie)頭之(zhi)前應把導線(xian)上的(de)(de)絕(jue)緣(yuan)剝(bo)(bo)除。用電(dian)(dian)工(gong)刀(dao)(dao)切(qie)剝(bo)(bo)時,刀(dao)(dao)口千萬別(bie)傷(shang)著(zhu)芯(xin)線(xian)。常用的(de)(de)剝(bo)(bo)削(xue)(xue)方(fang)法(fa)有級段(duan)剝(bo)(bo)落和斜削(xue)(xue)法(fa)剝(bo)(bo)削(xue)(xue)，電(dian)(dian)工(gong)刀(dao)(dao)的(de)(de)刀(dao)(dao)刃部分要(yao)磨(mo)得(de)(de)鋒利才好剝(bo)(bo)削(xue)(xue)電(dian)(dian)線(xian)。但不(bu)可太鋒利，太鋒利容(rong)易削(xue)(xue)傷(shang)線(xian)芯(xin)，磨(mo)得(de)(de)太鈍，則無法(fa)剝(bo)(bo)削(xue)(xue)絕(jue)緣(yuan)層。

8、圓木與木槽板或塑料槽板的吻接凹槽,就(jiu)可采用(yong)電(dian)工(gong)刀在施工(gong)現(xian)場切削。通常用(yong)左手托(tuo)住圓木,右手持(chi)刀切削。

9、利用電工刀同時還可(ke)以削(xue)制木榫、竹榫等。
