Mfundo Zofunika Kwambiri

• Kudula pogwiritsa ntchito kulemera kumakhudza zomwe kudula pogwiritsa ntchito kutalika sikungathe kuchita: kuchulukana kwa zinthu ndi makulidwe a pepala zimasiyana, kotero kutalika kofanana sikubweretsa kulemera kofanana.
• Makina odulira kulemera a XCJ-A 600 odzipangira okha amaphatikiza sensa yolemera ya LASCAUX yokhala ndi Delta PLC control, kudula molingana ndi momwe wogwiritsa ntchito amalolera ndikusankha chidutswa chilichonse chokha.
• Kudula ma preforms mpaka pawindo lolemera kwambiri (monga ± 0.3 g) kumachepetsa zinyalala zolemera kwambiri komanso zinyalala zomangira zinthu zosalemera kwambiri nthawi imodzi.
• Ikani zidutswa zomwe mukufuna pa nkhungu iliyonse (6 kapena 10) pazenera logwira ndipo makinawo amawonjezera kuwerengera kolondola, kuchotsa kuwerengera pamanja ndi kugwira kawiri.

Mphete za O ndi zinthu zomangira zomwe zimapangidwa kwambiri mumakampani opanga mphira, ndipo mphete iliyonse ya O-ring yopangidwa imakhala ndi kuwala pamzere wake wolekanitsa. Kusankha makina ochotsera mpweya kumakhudza osati mawonekedwe okongola a mphete ya O-ring yokha komanso magwiridwe ake otsekera, kusinthasintha kwa mawonekedwe ake, komanso mtengo wopangira. Bukuli limapereka njira yowerengera yogwirizanitsira zida zochotsera mpweya ndi magawo opanga mphete ya O-ring.

Zofunikira pa O-Ring Deflashing: Chomwe Chimawasiyanitsa ndi Zigawo Zina za Rubber

Mphete za O-ring zimakhala ndi zovuta zingapo zochotsera mpweya zomwe sizipezeka muzinthu zina za rabara. Chifukwa nkhungu imodzi ya O-ring imapanga mabowo ambirimbiri kapena mazana ambiri, kuwala kwa mzere wolekanitsa kumadutsa m'mimba mwake wamkati ndi kunja kwa mphete iliyonse. Gawo lopyapyala - magawo opingasa a O-ring wamba amakhala kuyambira 1.5 mm mpaka 8.4 mm paISO 3601-1— zikutanthauza kuti kuwalako kuli pafupi ndi malo otsekera omwe amagwira ntchito. Kuchotsa madzi ambiri m'malo olumikizira kuwalako kumapanga njira yotayikira madzi yomwe singathe kuzindikirika ndi kuyang'ana maso kokha.

Kuphatikiza apo, mphete za O zimagawidwa m'magulu aASTM D1414pa njira zoyesera zokhazikika, zomwe zimatchula njira zotsimikizira kuti kuyeretsa sikuyenera kusokoneza.ISO 3302-1, kulekerera kwa miyeso ya mphete za O zolondola kumayambira pa ±0.08 mm pa zigawo zopingasa zosakwana 2.5 mm mpaka ±0.22 mm pa zigawo zopingasa zopitirira 10 mm. Njira yochotsera kuwala iyenera kuchotsa kuwalako popanda kusintha miyeso yofunikayi.

Chinthu chosadziwika bwino koma chofunikira kwambiri ndi malo a flash. Ma O-ring mold nthawi zambiri amakhala ndi mzere wolekanitsa pakati pa mold, zomwe zikutanthauza kuti flash imakhala mwachindunji pa dayamita ya seal. Deflashing yomwe imasiya yotsalira kuposa 0.1 mm pa ID kapena OD imapanga vuto lotseka lomwe limayambitsa kutuluka kwa mpweya pamlingo wovomerezeka. Choletsa ichi chimapangitsa kusankha njira yochotsera mpweya kukhala kofunikira kwambiri pa O-rings kuposa pazigawo za rabara zosawoneka bwino komwe flash siili pamalo ogwirira ntchito.

Zinthu Zisanu Zosankha Posankha Makina Ochotsera Mphira a O-Rings

Chinthu 1: Kukula kwa O-Ring ndi Gawo Lopingasa

Miyeso yeniyeni ya mphete zanu za O imakhazikitsa malire oyamba a zida. Makina ochotsera ng'oma amakina amagwira ntchito mkati mwa mulingo wodziwika bwino.Makina ochotsera ng'oma a XCJ-G600, yokhala ndi m'mimba mwake wa ng'oma ya 600 mm ndi mphamvu ya batch ya 15 kg, imapanga mphete za O kuyambira 3 mm mpaka 100 mm m'mimba mwake wakunja. Mphete za O zochepera 3 mm nthawi zambiri zimadutsa m'mabowo a ng'oma kapena chisa m'magulu, zomwe zimachepetsa mphamvu yotulutsa mpweya. Mphete za O zopitirira 100 mm OD zimafuna ng'oma yayikulu kapena njira ina yogwiritsira ntchito.

Magawo opingasa nawonso ndi ofunika. Mphete zopyapyala za O zomwe zili ndi magawo opingasa pansi pa 2 mm zimakhala zosavuta kugwedezeka komanso kuwonongeka pamwamba pa makina akagubuduzika. Pa izi, kukonza cryogenic ndiye chisankho chotetezeka chifukwa rabara yozizira imakhala ngati chinthu cholimba ikagubuduzika. Lamulo lothandiza lomwe timagwiritsa ntchito mufakitale yathu:Mphete za O-rings zokhala ndi gawo lopingasa ≥2.5 mm ndi OD pakati pa 8 mm ndi 80 mm ndi zoyenera kwambiri pochotsa ng'oma yamakina, pomwe mphete za O-rings zomwe zili kunja kwa mtunda uwu ziyenera kuyesedwa kuti zigwiritsidwe ntchito ngati cryogenic.

Chinthu Chachiwiri: Mbiri ya Flash ndi Mtundu wa Zinthu

Kukhuthala kwa Flash ndiye chinthu chofunikira kwambiri pa njira. Kuchotsa mpweya m'thupi pogwiritsa ntchito makina kumagwira ntchito bwino pamene chiŵerengero cha makulidwe a flash-to-part ndi 0.1 kapena kupitirira apo — zomwe zikutanthauza kuti mphete ya O-section ya 3.5 mm yokhala ndi flash ya 0.35 mm ikhoza kuchotsedwa m'thupi pogwiritsa ntchito makina, pomwe mphete ya 1.8 mm yokhala ndi flash ya 0.15 mm siyingachotsedwe m'thupi pogwiritsa ntchito makina, pomwe mphete za O-ring zomwe zimapangidwa ndi zida zapamwamba kwambiri zomwe flash nthawi zambiri zimakhala 0.1-0.3 mm, zinthuzo zimatsimikiza ngati kuchotsa mpweya m'thupi pogwiritsa ntchito makina kapena cryogenic ndikoyenera.

Kukhuthala kwa kuwala komwe kumayesedwa pamalo okhuthala kwambiri a mzere wolekanitsa nkhungu. Mitengo yeniyeni ingasiyane malinga ndi kapangidwe kake ndi momwe nkhungu ilili.

Chinthu Chachitatu: Kuchuluka kwa Kupanga ndi Kukula kwa Gulu

XCJ-G600 imakonza gulu la 15 kg la mphete za O mu masekondi 20-40 pa nthawi iliyonse. Pa kulemera kwapakati kwa mphete za O-ring za 2-10 magalamu kutengera kukula, gulu limodzi lili ndi mphete za O-ring za 1,500-7,500. Pa masekondi 40 pa gulu lililonse lodzaza ndi katundu ndi kutsitsa katundu, mphamvu yogwira ntchito ndi pafupifupi magulu 60-80 pa nthawi iliyonse ya maola 8, kapena mphete za O-ring za 90,000-600,000 pa nthawi iliyonse kutengera kukula kwake.

Kupanga kwakukulu kopitilira 500,000 O-rings patsiku kungathandize kuti mzere wodziyimira pawokha wa cryogenic ukhale wosiyana ndi kukula kwake ndi mzere wodziyimira pawokha wa makina, koma kwa opanga ambiri apakatikati, makina amodzi ogwiritsira ntchito ng'oma amagwira 80-90% ya ndalama zonse za O-ring.Zotsala 10-20% — nthawi zambiri zimakhala silicone kapena sub-6 mm ID O-rings — zitha kugulitsidwa kunja kapena kugwiritsidwa ntchito pamakina ang'onoang'ono a cryogenic batch.

Chinthu 4: Gulu la Kulekerera ndi Zofunikira pa Ubwino

ISO 3302-1 imagawa zololera za zinthu za rabara m'magulu anayi. Kalasi A (yolondola) imafuna ±0.08 mm pa magawo opingasa osakwana 2.5 mm. Kalasi B (yochepa) imafuna ±0.10 mm. Kalasi C (yapakatikati) imafuna ±0.14 mm. Njira yochotsera kuwala iyenera kukhala yokhoza kuchotsa kuwala mkati mwa gulu lololera popanda kuchepetsa gawo lopingasa pansi pa gawo locheperako lololedwa. Kuchotsa kuwala kwa makina pogwiritsa ntchito njira yoyenera yolumikizirana kumakwaniritsa kulolerana kwa Kalasi B ndi C nthawi zonse. Kuchotsa kuwala kwa cryogenic, komwe kumayendetsedwa bwino ndi kuchotsa zinthu, kumakwaniritsa kulolerana kwa Kalasi A ndi B kwa mphete za O zokhala ndi magawo opingasa opyapyala.Ngati mfundo zanu za O-ring zikufuna kuti mukhale ndi ma tolerance a Class A pa cross-sections osakwana 3 mm, cryogenic deflashing ikulangizidwa kwambiri.

Chinthu 5: Mtengo Wonse wa Ntchito (TCO)

Zinthu ziwiri zomwe zimawononga nthawi zambiri zimachepetsedwa posankha makina ochotsera mpweya: kugwiritsa ntchito zinthu zosungira mpweya ndi zinthu zosungira madzi ndi nayitrogeni. Kuchotsa mpweya pogwiritsa ntchito makina kumafuna zinthu zosungira mpweya (pulasitiki kapena walnut shell pellets) zomwe zimafunika kusinthidwa nthawi ndi nthawi. Kuchotsa mpweya pogwiritsa ntchito cryogenic kumafuna nayitrogeni wamadzimadzi pa 0.5-2.5 kg pa kg iliyonse ya rabara yokonzedwa, kutengera kulemera kwake ndi kuchuluka kwake.

Mitengo yochokera ku ziyerekezo za 2026 kotala lachiwiri la zida zomwe zikugwira ntchito ku China. Mitengo ya LN2 imasiyana m'madera osiyanasiyana; kutumiza zinthu zambiri kumachepetsa mtengo ndi 15-25%.

Ndondomeko Yosankha: Ndi Makina Otani Ochotsera Mphira a O-Rings Oyenera Kupanga Kwanu?

Opanga ambiri amagwiritsa ntchito njira zosiyanasiyana: makina ochotsera ng'oma a XCJ-G600 amayendetsa kupanga koyamba kwa NBR ndi EPDM, pomwe makina ang'onoang'ono a cryogenic amayendetsa ma silicone ndi ma FKM O-rings omwe amaimira 10-20% ya kusakaniza kwa mankhwala. Dongosololi limakulitsa kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito kwambiri komanso kusunga mtundu wa mankhwala apadera.

Pomaliza: Gwirizanitsani Makina Ochotsera Madzi ndi O-Ring Portfolio Yanu

Palibe makina abwino kwambiri ochotsera mphira a mphira a mphete za O. Kusankha kolondola kumadalira kukula kwa mphete za O, mtundu wa zinthu, momwe zimakhalira, kuchuluka kwa kupanga, ndi zofunikira pakulekerera. Kuchotsera mphira wa ng'oma pogwiritsa ntchito XCJ-G600 ndiye njira yotsika mtengo kwambiri ya mphete za NBR ndi EPDM O zomwe zili mu OD ya 6-90 mm, zomwe zimapereka nthawi ya masekondi 20-40 pa 15 kg pa batch iliyonse. Kuchotsera mphira wa cryogenic kumakhala kofunikira pa mphete za silicone ndi FKM O, ma ID ang'onoang'ono osakwana 6 mm, ndi ntchito zolondola za Class A. Pa malo opangira zinthu zosiyanasiyana, kugwiritsa ntchito njira zonse ziwiri nthawi imodzi kumawonjezera kusinthasintha popanda kuwononga ndalama zambiri pazinthu zodziwika bwino.
