CNC kutembenuza ndondomeko Yowonetsedwa Chithunzi

Njira yosinthira CNC

Kufotokozera Kwachidule:

Kutembenuza kwa CNC ndi njira yopangira makina momwe chida chodulira, chomwe sichimazungulira, chimafotokozera njira ya helix poyenda mozungulira mozungulira pomwe chogwiriracho chikuzungulira.

Kusintha kwa CNC

Kutembenuza kwa CNC ndi njira yopangira makina momwe chida chodulira, chomwe sichimazungulira, chimafotokozera njira ya helix poyenda mozungulira mozungulira pomwe chogwiriracho chikuzungulira.

Nthawi zambiri mawu oti "kutembenuka" amasungidwa m'badwo wa mawonekedwe akunja ndi kudula uku, pomwe njira yodulira yofananayi ikagwiritsidwa ntchito kumalo amkati (mabowo, amtundu wina) amatchedwa "wotopetsa".Choncho mawu akuti "kutembenuka ndi wotopetsa" amaika gulu lalikulu la njira zotchedwa lathing.Kudulidwa kwa nkhope pa chogwirira ntchito, kaya ndi chida chotembenuza kapena chotopetsa, chimatchedwa "kuyang'ana", ndipo chikhoza kuphatikizidwa mumagulu onse monga gawo laling'ono.

Kutembenuza kungathe kuchitidwa pamanja, mwachizoloŵezi cha lathe, chomwe nthawi zambiri chimafuna kuyang'aniridwa mosalekeza ndi wogwiritsa ntchito, kapena pogwiritsa ntchito lathe lodzichitira lomwe silitero.Masiku ano mtundu wodziwika kwambiri wa makina oterowo ndiwowongolera manambala apakompyuta, omwe amadziwika kuti CNC.(CNC imagwiritsidwanso ntchito ndi mitundu ina yambiri yamakina kuphatikiza kutembenuka.)

Potembenuza, chogwiriracho (chidutswa cha zinthu zolimba monga matabwa, chitsulo, pulasitiki, kapena mwala) chimazunguliridwa ndipo chida chodulira chimadutsa ndi nkhwangwa 1, 2, kapena 3 zoyenda kuti zipangitse mainchesi ndi kuya kwake.Kutembenuza kumatha kukhala kunja kwa silinda kapena mkati (yomwe imadziwikanso kuti yotopetsa) kuti ipange zigawo za tubular kumitundu yosiyanasiyana.Ngakhale kuti tsopano ndi osowa, lathe oyambirira angagwiritsidwe ntchito kupanga ziwerengero zovuta za geometric, ngakhale zolimba za platonic;ngakhale kuyambira kukhazikitsidwa kwa CNC zakhala zachilendo kugwiritsa ntchito njira zowongolera zopanda makompyuta pazolinga izi.

Njira zokhotakhota nthawi zambiri zimachitika pa lathe, lomwe limatengedwa kuti ndi zida zakale kwambiri zamakina, ndipo zimatha kukhala zamitundu yosiyanasiyana monga kutembenuka mowongoka, kutembenuza taper, mbiri kapena grooving yakunja.Njira zokhotakhotazi zimatha kupanga zinthu zosiyanasiyana monga zowongoka, zopindika, zopindika, kapena zopindika.Nthawi zambiri, kutembenuza kumagwiritsa ntchito zida zosavuta zodulira mfundo imodzi.Gulu lililonse la zida zogwirira ntchito lili ndi zida zabwino kwambiri zomwe zapangidwa zaka zambiri.

Zidutswa zazitsulo zotayidwa kuchokera ku ntchito zotembenuza zimadziwika kuti tchipisi (North America), kapena swarf (Britain).M'madera ena amatha kutchedwa kutembenuka.

Nkhwangwa zachidazo zimatha kukhala zowongoka, kapena zimatha kukhala zokhotakhota kapena ngodya zina, koma zimakhala zozungulira (mopanda masamu).

Chigawo chomwe chikuyenera kusinthidwa chitha kutchedwa "Turned Part" kapena "Machined Component".Kutembenuza kumachitika pamakina a lathe omwe amatha kugwira ntchito pamanja kapena CNC.

Kutembenuza kwa CNC kutembenuza njira kumaphatikizapo

Kutembenuka
Njira yowonongeka imaphatikizapo kusinthasintha gawo pamene chida chodulira chimodzi chimasunthidwa mofanana ndi mzere wozungulira.Zomwe zimayambira nthawi zambiri zimakhala chogwirira ntchito chomwe chimapangidwa ndi njira zina monga kuponyera, kupanga, kutulutsa, kapena kujambula.

Kutembenuka kwamatepi
Kutembenuka kwa tapered kumapanga mawonekedwe a cylindrical omwe amachepa pang'onopang'ono m'mimba mwake kuchokera kumapeto mpaka kumapeto.Izi zitha kutheka a) kuchokera pagulu lopanda b) kuchokera ku taper kutembenuza chophatikizira c) kugwiritsa ntchito cholumikizira cha hydraulic d) kugwiritsa ntchito CNC lathe e) pogwiritsa ntchito chida cha mawonekedwe f) pochotsa tailstock - njira iyi ndi yoyenera kwambiri pakuzama. zokopa.

Mbadwo wozungulira
Mbadwo wozungulira umapanga malo ozungulira ozungulira potembenuza mawonekedwe ozungulira.Njira zikuphatikizapo a) kugwiritsa ntchito hydraulic copy attachment b) CNC (computerised numberally controlled) lathe c) pogwiritsa ntchito chida cha mawonekedwe (njira yovuta komanso yokonzeka) d) pogwiritsa ntchito bedi jig (mufunika kujambula kuti mufotokoze).

Kutembenuka mwamphamvu
Kutembenuza molimba ndi mtundu wa kutembenuza kochitidwa pazida zolimba za Rockwell C zokulirapo kuposa 45. Nthawi zambiri zimachitika chogwirira ntchito chikatenthedwa.
Ndondomekoyi ikufuna kusintha kapena kuchepetsa ntchito zachikhalidwe zogaya.Kutembenuza mwamphamvu, kukagwiritsidwa ntchito pofuna kuchotsa katundu, kumapikisana bwino ndi kugaya movutikira.Komabe, ikagwiritsidwa ntchito pomaliza pomwe mawonekedwe ndi kukula kwake ndizofunikira, kugaya ndikopambana.Kupera kumapanga kulondola kwapamwamba kwambiri kwa kuzungulira ndi cylindricity.Kuphatikiza apo, malo opukutidwa a Rz=0.3-0.8z sangathe kukwaniritsidwa ndi kutembenuka kolimba kokha.Kutembenuza mwamphamvu ndi koyenera pazigawo zomwe zimafuna kulondola kozungulira kwa 0.5-12 ma micrometres, ndi/kapena kukhaula pamwamba kwa Rz 0.8–7.0 micrometres.Imagwiritsidwa ntchito pamagiya, zida zapampu za jakisoni, ndi zida za hydraulic, pakati pazinthu zina.

Kuyang'ana
Kuyang'ana pa nkhani yotembenuza ntchito kumaphatikizapo kusuntha chida chodulira pamakona olondola kumtunda wa kuzungulira kwa workpiece yozungulira.Izi zitha kuchitika pogwiritsa ntchito mtandawo, ngati wayikidwa, wosiyana ndi chakudya chautali (kutembenuka).Kaŵirikaŵiri ndi ntchito yoyamba imene imachitidwa popanga chogwiritsiridwa ntchito, ndipo nthaŵi zambiri chomalizira—chotero mawu akuti “kumaliza”.

Kulekanitsa
Njirayi, yomwe imatchedwanso kulekanitsa kapena kudulidwa, imagwiritsidwa ntchito popanga ma grooves ozama omwe amachotsa gawo lomaliza kapena gawo lathunthu kuchokera m'makolo ake.

Grooving
Grooving ili ngati kulekanitsa, kupatula kuti grooves amadulidwa mozama kwambiri m'malo modula gawo lomaliza / gawo lathunthu kuchokera ku katundu.Grooving akhoza kuchitidwa pa malo mkati ndi kunja, komanso pa nkhope ya gawo (nkhope grooving kapena trepanning).

Zochita zosakhazikika zimaphatikizapo:
Zotopetsa
Kukulitsa kapena kusalaza dzenje lomwe lilipo lopangidwa ndi kubowola, kuumba, etc. mwachitsanzo, kupanga ma cylindrical mkati (kupanga) a) pokweza chogwirira ntchito ku spindle kudzera pa chuck kapena faceplate b) pokweza chogwirira ntchito pamtanda ndikuyika chida chodulira mkati. chuck.Ntchitoyi ndi yoyenera kwa ma castings omwe ndi ovuta kuyika pa mbale ya nkhope.Pa bedi lalitali lathes lalikulu workpiece akhoza bolts kwa fixture pa bedi ndi kutsinde kudutsa pakati pa zipilala ziwiri pa workpiece ndi lugs akhoza wotopetsa kukula.Ntchito yocheperako koma yomwe imapezeka kwa wotembenuza / wamakina waluso.

Kubowola
Amagwiritsidwa ntchito kuchotsa zinthu mkati mwa workpiece.Njirayi imagwiritsa ntchito zida zobowola zomwe zimayikidwa mokhazikika mumchira kapena turret ya zida za lathe.Njirayi ikhoza kuchitidwa ndi makina obowola omwe alipo padera.

Knurling
Kudula kwa mawonekedwe a serrated pamwamba pa gawo kuti agwiritse ntchito ngati chogwira pamanja kapena ngati chowonjezera chowonekera pogwiritsa ntchito chida chapadera chogogoda.

Kukonzanso
Ntchito yoyesa yomwe imachotsa chitsulo pang'ono pabowo lomwe labowoledwa kale.Zimapangidwa popanga mabowo amkati a diameter yolondola kwambiri.Mwachitsanzo, dzenje la 6mm limapangidwa pobowola ndi 5.98 mm kubowola pang'ono ndikusinthidwanso ku miyeso yolondola.

Ulusi
Ulusi wa screw wamba komanso wosakhazikika ukhoza kuyatsidwa pa lathe pogwiritsa ntchito chida choyenera chodulira.(Nthawi zambiri amakhala ndi ngodya ya mphuno ya 60, kapena 55 °) Kaya kunja, kapena mkati mwa bore(Kugunda ndi njira yopanga ulusi wamkati kapena wakunja mu chidutswa chogwirira ntchito. Nthawi zambiri amatchedwa ulusi wa mfundo imodzi.

Kumenya mtedza ndi mabowo a ulusi a) kugwiritsa ntchito matepi a m'manja ndi tailstock center b) kugwiritsa ntchito chipangizo chopopera chokhala ndi zomangira kuti muchepetse chiopsezo cha kusweka kwa mpopi.

Ntchito zopangira ulusi zikuphatikiza a)mitundu yonse yamitundu yakunja ndi yamkati yogwiritsa ntchito chida chimodzi chokha komanso ulusi wopota, ulusi woyambira pawiri, ulusi woyambira wambiri, nyongolotsi monga momwe amagwiritsidwira ntchito m'mabokosi ochepetsera mphutsi, otsogolera okhala ndi ulusi umodzi kapena wambiri.b) Pogwiritsa ntchito mabokosi opangira ulusi okhala ndi zida za 4, ulusi mpaka 2" m'mimba mwake koma ndizotheka kupeza mabokosi akulu kuposa awa.

Kutembenuka kwa polygonal
Momwe mawonekedwe osakhala ozungulira amapangidwa popanda kusokoneza kusinthasintha kwa zopangira.
