方孔鉆頭原理是什么
方(fang)(fang)孔(kong)鉆(zhan)主(zhu)要(yao)(yao)是用于(yu)木工(gong)(gong)(gong)方(fang)(fang)面。其原因(yin)在于(yu)存在一(yi)個沖(chong)擊(ji)體(ti)(ti)(ti),采用這種(zhong)工(gong)(gong)(gong)作原理(li)用于(yu)鉆(zhan)鋼、鐵,材料,對刀具(ju)強度要(yao)(yao)有(you)很高(gao)的要(yao)(yao)求(qiu)。具(ju)體(ti)(ti)(ti)原理(li)如下:方(fang)(fang)孔(kong)鉆(zhan)頭(tou),屬于(yu)一(yi)種(zhong)五(wu)金(jin)工(gong)(gong)(gong)具(ju),主(zhu)要(yao)(yao)由內旋轉沖(chong)擊(ji)體(ti)(ti)(ti)和(he)外沖(chong)擊(ji)體(ti)(ti)(ti)組成(cheng)。現有(you)的各種(zhong)鉆(zhan)頭(tou),只能加(jia)(jia)工(gong)(gong)(gong)圓(yuan)(yuan)形孔(kong),不能加(jia)(jia)工(gong)(gong)(gong)方(fang)(fang)形孔(kong),若要(yao)(yao)加(jia)(jia)工(gong)(gong)(gong)方(fang)(fang)孔(kong),必(bi)須用圓(yuan)(yuan)孔(kong)鉆(zhan)頭(tou)或切割機加(jia)(jia)工(gong)(gong)(gong)出粗孔(kong)后,再(zai)由人工(gong)(gong)(gong)手鑿而(er)成(cheng)。

木工方孔鉆頭的操作方法
木工方孔鉆是(shi)用在方榫機(ji)上的 專用(yong)(yong)開方(fang)孔(kong),鎖孔(kong)鉆(zhan)頭(tou),如果沒(mei)有方(fang)榫機器(qi),在臺鉆(zhan),電鉆(zhan)上先用(yong)(yong)鉆(zhan)芯多開幾個孔(kong),再用(yong)(yong)方(fang)孔(kong)鉆(zhan)的(de)外套敲擊(ji),敲擊(ji)的(de)時候(hou)要慢。
木工方孔鉆在用內旋轉體鉆出圓孔的同時,利用電錘傳遞給外(wai)沖(chong)(chong)擊體的(de)(de)沖(chong)(chong)擊力,破碎(sui)圓孔(kong)與方(fang)(fang)頭壁之(zhi)間的(de)(de)材料,一(yi)次性加工(gong)(gong)成(cheng)方(fang)(fang)孔(kong),且碎(sui)塵能從(cong)出渣管排出。利(li)用(yong)不同規格的(de)(de)方(fang)(fang)孔(kong)鉆頭,選配適(shi)當功(gong)率(lv)的(de)(de)方(fang)(fang)孔(kong)機,就(jiu)可打(da)出符合(he)要求的(de)(de)方(fang)(fang)孔(kong)。可減輕施工(gong)(gong)員的(de)(de)勞(lao)動強度(du),加快施工(gong)(gong)速度(du),降(jiang)低施工(gong)(gong)成(cheng)本,適(shi)合(he)建筑施工(gong)(gong)、安裝、裝修(xiu)、裝飾行業使用(yong)。
