Kudula liwiro pa mphero, kutembenuka, ndi zina Machining

Mawerengedwe a zinthu kudula - ichi ndi chinthu chofunika kwambiri kupanga mbali iliyonse. Nkofunika kuti anali zomveka. Ichi ndi chifukwa ntchito iliyonse makina zofunika payekha kukatenga kudula liwiro, liwiro spindle, mlingo chakudya, ndi makulidwe a khungu wosanjikiza. Zomveka mode - ndi zimenezi, imene ndalama yopanga adzakhala kochepa, ndipo khalidwe la mankhwala - monga yeniyeni ngati nkotheka.

Zoyamba za kuthetsa

Kuti apange katunduyo ndi kukula chofunika ndi olondola kalasi, makamaka ntchito zojambula zake ndi kupaka luso wam'mbuyomu. Komanso, n'kofunika kusankha akusowekapo zolondola (kulipira, mitundu, pakubwezeretsa) ndi chuma anakhumba imene mankhwala adzakhala umatulutsa. Kusankha kudula zipangizo - ndi ndithu yofunika kwambiri. Pakuti aliyense ntchito anasankha zofunika chida (wodula, wodula, kubowola, countersink).

Komanso, wachina chilichonse, zinalembedwa luso yolozera, njira zosiyana ikuchitika, ngakhale ntchito pamwamba yomweyo ntchito. Mwachitsanzo, m'pofunika kuti dzenje D = 80 mamilimita mkati ndi kuwaza chinkafunika ulusi ndi phula P = 2 mm. Pakuti aliyense wa ntchito zofunika kwa padera kukatenga zinthu zofunika monga akuya odulidwa, kudula liwiro, liwiro, ndi kuwonjezera, kukatenga kudula chida.

Adakhumba khalidwe pamwamba

Nkofunika kuganizira komanso mtundu wa processing (kuwamaliza, wosemera ndi) chifukwa kusankha koefishienti mu mawerengedwe chimadalira pa magawo awa. Monga ulamuliro, pa wosemera kudula liwiro ndi apamwamba kuposa pamene akutha. Zimenezi zalongosoledwa motere: bwino khalidwe la pamwamba anamuchitira ang'onoang'ono ayenera kukhala liwiro lake. N'zochititsa chidwi kuti pa kusandutsa titaniyamu kasakaniza wazitsulo roughness mtengo ukuwonjezeka pa ziwawa, monga woyendera nthambi processing pali kusinthasintha amphamvu, koma pa magawo Ra ndi Rz iwo ali mwamtheradi zopanda phindu.

Zinthu zokhudza kudula liwiro mu mphero ndi ntchito zina

nambala yaikulu kuganizira zinthu kusankha Pamudzi. Iwo onse zosiyana kwa wina malingana ndi mtundu wa workpiece. Mwachitsanzo, chifukwa mabowo pobowola akhoza anasankha pa kawiri kuposa pobowola. Ndiponso, izi chizindikiro pa processing popanda kuchepetsa zinthu anasankha pazipita chovomerezeka mphamvu monga chida ntchito. _. Pamene planing ndi kudula mipata mu zofunika chilinganizo kudula boma anawonjezera chimene chimachititsa kuti amadza katundu - K _v.

Pamene threading Nkofunika kulabadira kusankha kudula zipangizo komanso ntchito chida kuti akwaniritse amafuna Buku kuchotsa, motero mlingo ayenera kukhala kochepa.

Kudula liwiro pa mphero zimadalira chida awiri (D) ndipo m'lifupi padziko (B). Komanso, processing wa pamalo zitsulo endmill akusowekapo kwenikweni pabwino asymmetrically wachibale kudula chida. Ngati sitisamala lamulo limeneli, kukana yake kwambiri yafupika.

Izi ndi chinthu chofunika kwambiri, zimene zimakhudza mawerengedwe a kudula liwiro. Amatanthauza nthawi ya kudula chida patsogolo ndi yosamveka. Nthawi ya kukana kumawonjezera pamene mnogoinstrumentalnoy processing.

chilinganizo zoyambirira

Kudula liwiro pa ntchito iliyonse makamaka zimadalira kudula chida ku workpiece chuma, kuya ndi mwa kundipatsako kuchuluka. Pa njira yake chilinganizo amakhudza Machining. Kudula liwiro angathe tabular njira ndi mwa mawerengedwe. Choncho, wotopetsa komanso akunja, yopingasa ndi kotenga kutembenuza ntchito chilinganizo anasonyeza pansipa.

Kodi mawerengedwe ili ndi losiyana ndi enawo? Pamene akatembenukira woboola pakati, kudula ndi kudula akuya kudula si n'komwe. Koma nthawi zina, akhoza kutenga mtengo uwu kachigawo kagawo lapansi. Naprmer, ndi processing m'lifupi kutsinde la tidzakambirana monga awiri ake, ndi pa vytachivanii poyambira - kuya kwake. Chifukwa chakuti pamene kudula kuchita kuchotsa wodula ndi m'malo ovuta, salinso anasankha chakudya 0.2 mamilimita / Mbusa ndi kudula liwiro - 10-30 mamilimita / min. Mukhozanso kuchita kuwerengetsera pa chilinganizo osiyana.

Pamene tikubooleza, reaming, wotopetsa ndipo analamula Nkofunika kudziwa kudula liwiro ndi chakudya. Ndi mfundo yaikulu kwambiri ya kudula chida akhoza "kuwotcha" kapena kusiya. Pakuti kuwerengetsera ntchito mu pobowola chilinganizo pansipa.

Kudula liwiro pa mphero wodula zimadalira awiri, chiwerengero cha mano ndipo m'lifupi pamwamba machined. mozama Selectable chifukwa cha chinthu chimodzimodzi ndi mphamvu za makina, komanso ankamvetsa pambali. Mtengo wa kulimbikira wodula amadalira awiri ake. Choncho, ngati D = 40-50 mm, ndiye T = 120 min. Pamene D ndi mu osiyanasiyana 55-125 mm, mlingo wa T liri mphindi 180. Kudula liwiro pamene mphero ali chilinganizo tikuonera chithunzi.

Bakuman:

C _ndime - koyefishienti, potsata pa katundu makina a padziko ankachitira.

T - moyo kudula chida.

S - chakudya wambiri.

T - akuya odulidwa.

B - m'lifupi mphero

z - chiwerengero cha mano a wodula lapansi.

D - awiri a dzenje machined (mu zina kudula chida monga kubowola a)

m, ×, Y - exponents (osankhidwa matebulo) amene anatsimikiza zinthu zenizeni kudula ndipo amakonda kukhala ndi makhalidwe a mamita = 0,2; × = 0,1; Y = 0.4.

K _ndime - kudzudzulidwa china. M'pofunika, monga anapezazo ndi akutsatiridwa ndi thandizo la koefishienti otengedwa magome. ntchito zake zimathandiza kupeza phindu lenileni la kudula liwiro, kutenga zinthu chifukwa mfundo yeniyeni tatchulazi.

Table ndi njira mapologalamu

Popeza kuchita kuwerengetsera - ndi nthawi wonyeketsa ndondomeko, pali matebulo wapadera mabuku apadera ndi pamanambala zosiyanasiyana Internet, amene kale mwachindunji magawo chofunika. Komanso, pali mapulogalamu amachita ndi mawerengedwe zinthu kudula. Kwa mtundu uwu anakhumba amusankha ndipo inputted magawo Machining monga workpiece zakuthupi ndi kudula chida, miyeso zofunika, kuya, Qualitet molondola. Pulogalamu yokha linaŵerengera kudula liwiro kukubwezani, phula ndi rotational liwiro.
