Chithovu chapampando nthawi zambiri chimatanthawuza thovu la polyurethane, lomwe limapangidwa ndi zinthu ziwiri kuphatikiza zowonjezera ndi zina zazing'ono, zomwe zimapukutidwa ndi nkhungu.Ntchito yonse yopanga imagawidwa m'njira zitatu: siteji yokonzekera, siteji yopangira ndi siteji yomaliza.
1. Gawo lokonzekera - kuyendera komwe kukubwera + kusakaniza
①Kuwunika kwazinthu zomwe zikubwera:
Makamaka fufuzani ngati madzi ndi mamasukidwe akayendedwe a polyether kukwaniritsa zofunika.Chinthuchi ndi chofunika kwambiri m'nyengo yozizira kumpoto.
Kupanga kwa thovu kwaulere kumapangidwanso pazinthu zomwe zikubwera, makamaka zolemera kuti zitsimikizire ngati zikukwaniritsa zofunikira zopanga.
②Kusakaniza:
Kusakaniza kumachitika molingana ndi njira yokhazikitsidwa, ndipo zida zosakaniza zokha zimagwiritsidwa ntchito.Mpando thovu dongosolo FAW-Volkswagen lagawidwa mitundu iwiri: zinthu gulu ndi zinthu kudzikonda kusakaniza.
Zosakaniza :) A + B njira ziwiri zosakanikirana zimasakanizidwa mwachindunji
Kudziphatika: sakanizani POLY, ndiye kuti, polyether + POP + zowonjezera, ndiyeno sakanizani POLY ndi ISO.
2. Gawo lopanga - kupanga lupu
Nthawi zambiri, kupanga malupu kumatengedwa, makamaka kudzera munjira zingapo monga kuthira, kupanga, kugwetsa, ndikuyeretsa nkhungu motere:
Pakati pawo, kuthira ndi kiyi, yomwe imatsirizidwa makamaka ndi makina otsatsira.Njira zosiyanasiyana zothira zimagwiritsidwa ntchito molingana ndi malo osiyanasiyana a thovu la mpando, ndiye kuti, zithovu zimatsanulidwa m'magawo osiyanasiyana, ndipo magawo amasiyanasiyana (kupanikizika, kutentha, chilinganizo, kachulukidwe ka thovu, kuthira njira, cholozera).
3. Pomaliza kukonza - kuphatikizapo kubowola, kudula, kukopera, kukonza, kupopera sera silencer, kukalamba ndi zina.
①Hole - Cholinga chotsegulira ndikuletsa kusinthika kwazinthu ndikuwonjezera kukhazikika.Amagawidwa mu mtundu wa vacuum adsorption ndi mtundu wa roller.
Pambuyo potuluka chithovu mu nkhungu, m'pofunika kutsegula maselo mwamsanga.Kufupikitsa nthawi, bwino, komanso nthawi yayitali sayenera kupitirira 50s.
②M'mphepete yokonza-thovu Chifukwa cha ndondomeko ya utsi wa nkhungu, kung'anima kwa chithovu kumapangidwa m'mphepete mwa chithovu, chomwe chidzakhudza maonekedwe akuphimba mpando ndipo chiyenera kuchotsedwa ndi manja.
③Coding - yomwe imagwiritsidwa ntchito pofufuza tsiku lopangidwa ndi chithovu.
④Kukonza - Foam idzatulutsa zolakwika pang'ono panthawi yopanga kapena kugwetsa.Nthawi zambiri, guluu amagwiritsidwa ntchito kukonza zolakwika.Komabe, FAW-Volkswagen imanena kuti pamwamba A siloledwa kukonzedwa, ndipo pali miyezo yapadera yoletsa kukonzanso..
⑤Utsi phula losamva mawu - ntchitoyo ndikuletsa kukangana pakati pa thovu ndi chimango chapampando kuti pakhale phokoso.
⑥Kukalamba - Chithovu chikapangidwa kuchokera mu nkhungu, zinthu zomwe zimatulutsa thovu nthawi zambiri sizimakhudzidwa, ndipo ma micro-reaction amafunika.Nthawi zambiri, chithovucho chimayimitsidwa mlengalenga ndi catenary kwa maola 6-12 kuti chichiritsidwe.
kutsegula
Kuchepetsa
pambuyo kucha
Ndi ndendende chifukwa cha njira yovuta kotero kuti thovu la mpando wa Volkswagen limakhala ndi chitonthozo chabwino kwambiri komanso chitetezo cha chilengedwe ndi fungo lochepa komanso mpweya wochepa.
