Maupangiri Akatswiri Oyendetsa Bolt Thread, Werengani Nkhaniyi Ndikwanira!

Ulusi umagawika kwambiri mu ulusi wolumikiza ndi ulusi woyendetsa.

Pofuna kulumikiza ulusi, njira zazikuluzikulu ndikugwiritsira ntchito ulusi, kuluka, kutembenukira, kugubuduza, kupukuta, ndi zina zambiri. Pa ulusi wotumizira, njira zazikuluzikulu ndizopindika ndikusintha bwino - kugaya, kugaya kwa mphepo yamkuntho - kutembenuka koyipa ndi kutembenuka kwabwino, ndi zina zambiri.

Njira zotsatirazi ndizokonzanso:

1. Kudula ulusi

Nthawi zambiri, imagwiritsa ntchito njira yolumikizira ulusi pa chopangira chogwiritsira ntchito chopangira chopangira kapena chida chokhwimitsa, makamaka kuphatikiza, kugaya, kugogoda, kuluka, kugaya, ndi kudula mphepo yamkuntho, ndi zina zotero. Chida chamakina chimatsimikizira kuti chida chosinthira, chodulira mphero, kapena gudumu loyenda limatha kuyendetsa chitsogozo chimodzi molondola komanso wogawana panjira yolumikizira ya workpiece. Pakugwedeza kapena kulumikiza, chida (chojambula kapena chofa) chimazungulira poyerekeza ndi chogwirira ntchito, ndipo chida (kapena chopangira) chimasunthira mozungulira motsogozedwa ndi poyambira chopangira ulusi.

Ulusi wotsegulira lathe ukhoza kuchitika ndi chida chosinthira mawonekedwe kapena chida chachisa ulusi (onani chida chosakira ulusi). Kutembenuza ulusi ndi chida chosinthira mawonekedwe ndi njira yodziwika yopangira chidutswa chimodzi komanso kupanga batch yaying'ono chifukwa chosavuta; ulusi wosanja ndi wodula ulusi uli ndi kupanga kokwanira kwambiri, koma kapangidwe kake ndi kovuta, kotero ndi koyenera kokha pakupanga kwapakatikati ndi kwakukulu kwa chopangira ulusi chaching'ono ndi ulusi wawung'ono. Ambiri, molondola phula la kutembenukira trapezoidal ulusi ndi lathe wamba kokha kufika 8-9 kalasi (JB2886-81, yemweyo pansipa); zokolola kapena zolondola zitha kusinthidwa bwino mukamapanga ulusi pazolumikizira zapadera.

2. Ulusi wopera

Mphero imachitika pamakina opangira ulusi wokhala ndi chodulira kapena chodulira chisa. Chodulira chimbale cha disk chimagwiritsidwa ntchito popera ulusi wakunja wa trapezoidal pa ndodo ya wononga, nyongolotsi, ndi magwiridwe antchito ena. Chodulira chisa chimagwiritsidwa ntchito popera ulusi wamkati ndi wakunja wamba ndi ulusi wopota. Chifukwa chimagayidwa ndi chodulira chocheperapo komanso kutalika kwa gawo logwirira ntchito ndikokulirapo kuposa ulusi womwe ungakonzedwe, chogwirira ntchito chitha kukonzedwa ndi 1.25 ~ 1.5 kasinthasintha kokha, ndipo zokolola zake ndizokwera kwambiri. Kulondola kwa phula la mphero kumatha kufika 8-9 kalasi, ndipo mawonekedwe ake ndi R 5-0.63 μm. Njirayi ndioyenera kupanga ulusi wopangira ulusi mwatsatanetsatane kapena makina okhwima asanapere.

3. Ulusi wopera

Amagwiritsidwa ntchito popangira ulusi wolimbikira wa chopukusira ulusi. Malinga ndi mawonekedwe osiyanasiyana opingasa a gudumu, amatha kugawidwa kukhala gudumu limodzi lopera komanso magudumu angapo opera. Zotsatira zake zikuwonetsa kuti kulondola kwa phula la gudumu limodzi lokhala ndi magalasi 5-6, ndipo kukhathamira kwake ndi R 1.25-0.08 μm, Ndikosavuta kugaya magudumu. Njirayi ndioyenera kupukutira zomangira zotsogola, ulusi wopota, nyongolotsi, gulu laling'ono la cholumikizira, ndi kupukusa mwatsatanetsatane hob. Mipikisano mzere akupera gudumu akupera lagawidwa kotenga njira umapezeka ndi kudula mu njira umapezeka. M'lifupi gudumu akupera mu kotenga nthawi umapezeka njira n'chochepa kuposa kutalika kwa ulusi kukhala pansi, ndi ulusi akhoza pansi mpaka kukula komaliza mwa kusuntha gudumu kotenga nthawi kamodzi kapena kangapo. Kutalika kwa magudumu a kudula mu njira yopera ndikokulirapo kuposa kutalika kwa ulusi woti ugwere. Gudumu lopera limadula pamwamba pa chopangira mwaluso kwambiri, chombocho chimatha kumaliza pambuyo pa kusintha kwa 1.25. Zokolola ndi apamwamba, koma mwatsatanetsatane ndi pang'ono m'munsi, ndi mavalidwe a gudumu akupera ndi kovuta. Kudulidwa kwa njira yopera ndikoyenera kuthetsera matepi opera ndi batch yayikulu ndikupera ulusi wina wolimbitsa.
4. Ulusi wopera

Mtundu wa nati kapena ulusi wazida zopangira ulusi wopangidwa ndi zinthu zofewa monga chitsulo chomwe chimagwiritsidwa ntchito pogaya ziwalo za ulusi wopangika ndi cholakwika chakutsogolo kutsogolo ndikusinthira kasinthasintha kuti muwonetsetse kulondola kwa phula. Kusintha kwa ulusi wamkati wolimba nthawi zambiri kumachotsedwa ndikupera kuti musinthe molondola.
5. Kujambula ndi jacking

Kugogoda ndikugwiritsa ntchito kupindika kwakanthawi kuti uwononge mpopiyo mu dzenje loyeserera lantchitoyo kuti mugwiritse ulusi wamkati. Manjawo amagwiritsa ntchito kufa kudula ulusi wakunja pa ndodo (kapena chitoliro) chogwirira ntchito. Kutsimikizika kwamakina pogogoda kapena malaya kumatengera kulondola kwa matepi kapena kufa. Ngakhale pali njira zambiri zosinthira ulusi wamkati ndi wakunja, ulusi wamkati mwake wazing'onoting'ono ungodalira kukonzedwa kwapampopi. Kujambula ndikulumikiza kumatha kuchitika pamanja, monganso ma lathes, makina obowola, kulumikiza, ndi kulumikiza makina.

Kusankha mfundo kudula magawo kwa ulusi lathe

Chifukwa chojambulacho chimafotokozera ulusi (kapena lead) wa ulusi, chinsinsi chosankha magawo ochezera ndikuzindikira liwiro la spindle "n" ndikuchepetsa kuya "ap".

1) Kusankha liwiro spindle

Malinga ndi makina omwe spindle imazungulira, kutembenukira kumodzi ndipo chida chimadyetsa kutsogolera kumodzi potembenuza ulusi, liwiro la spindle lomwe lasankhidwa limatsimikizira kuthamanga kwa CNC lathe. Kutsogolera ulusi (phula ngati ulusi umodzi) mu gawo la pulogalamu yolumikizira ulusi ndikofanana ndi liwiro la chakudya "vf" lofotokozedwa ndi kuchuluka kwa chakudya "f (mm / r)".
vf = nf (1)

Titha kuwona kuchokera pamalingaliro kuti liwiro la chakudya "vf" ndilofanana molingana ndi kuchuluka kwa chakudya "f". Ngati liwiro la spindle la chida chamakina limasankhidwa kuti likhale lokwera kwambiri, liwiro la chakudya lotembenuzidwa liyenera kukhala lokwera kwambiri kuposa liwiro la zida zamakina. Chifukwa chake, magawo azakudya ndi kasinthidwe ka magetsi pazida zamakina ziyenera kuganiziridwa posankha liwiro la spindle potembenuza ulusi, kuti tipewe kupezeka kwa "ulusi wosokonezeka" kapena phula pafupi ndi poyambira / kumapeto komwe sikukumana zofunikira.

Kuphatikiza apo, ziyenera kuzindikirika kuti ulusi ukangoyamba kumene, mtengo wothamanga sungasinthidwe kawirikawiri, ndipo kuthamanga kwa spindle kuphatikiza kumaliza kumatha kugwiritsa ntchito mtengo womwe wasankhidwa pakudya koyamba. Kupanda kutero, makina a CNC amachititsa "ulusi wosokonekera" chifukwa cha "overshoot" ya chizindikiro chazomwe zimayambira pakulimba kwa pulse.

2) Kusankha kwa kudula kozama

Chifukwa cha mphamvu yazida zopanda mphamvu, chakudya chodulira chachikulu, ndi chakudya chocheka chocheperako kuchokera ku ulusi womwe umasandulika kukhala mawonekedwe otembenukira, zimafunikira kuti muchite makina osankhika ochepa ndikusankha kuzama kololera molingana ndi momwe zikuchepa. Tebulo 1 limatchulapo zofunikira za nthawi yazakudya komanso kuzama kwakanthawi kocheka ulusi wamba.
