Chopandacho chikhoza kupezedwa mwa kupanga. Chopanda sichikusowa kuumba chisanakhumudwitse, kuchepetsa m'mimba mwake ndi kukanikiza. Pambuyo podulidwa, imatumizidwa ku malo okhumudwitsa ogwirira ntchito. Siteshoniyi ikhoza kupititsa patsogolo ubwino wa zopanda kanthu, kuchepetsa kupanga mphamvu, 15ld moyo wotsatira, ndi kuwonjezera mphamvu ya 15ld 7 kulondola komwe kumatheka ndi kuzizira kwa mutu kumapanganso kumakhudzana ndi kusankha kwa kupanga njira ndi njira yogwiritsira ntchito.Kuonjezera apo, zimadaliranso makhalidwe apangidwe a zipangizo zomwe zimagwiritsidwa ntchito, makhalidwe a ndondomeko ndi chikhalidwe chawo, chida cholondola, moyo ndi kuvala degree.For mkulu aloyi zitsulo ntchito kuzizira mutu ndi extrusion, ntchito pamwamba roughness ya aloyi molimba kufa sikuyenera kukhala Ra = 0.2 roughness pamwamba pa ntchito, pamene ntchito pamwamba kufika pa tsi Ra = 0.025-0.050um, ili ndi moyo wapamwamba.
Ulusi wa bawuti nthawi zambiri umakonzedwa ndi kuzizira, kotero kuti wononga zopanda kanthu mkati mwa m'mimba mwake zimakulungidwa kudzera mu mbale ya ulusi (kufa), ndipo ulusiwo umapangidwa ndi kukakamiza kwa mbale ya ulusi (kufa). Amagwiritsidwa ntchito kwambiri chifukwa ulusi wa pulasitiki wa ulusi sunadulidwe, mphamvu imachulukitsidwa, kulondola ndipamwamba komanso khalidweli ndi yunifolomu. kaya zinthu ❖ kuyanika ndi zinthu zina.Kugudubuzika (kugudubuzika) kukanikiza ulusi ndi njira kupanga ulusi mano ndi pulasitiki deformation.It ndi ulusi ndi phula yemweyo ndi mawonekedwe conical wa kugubuduza (kugudubuza waya mbale) kufa, mbali imodzi kuti extrude cylindrical chipolopolo, mbali ina kupanga kasinthasintha chipolopolo, yomaliza kugubuduza kufa pa conical, mawonekedwe a ulusi, kotero kuti ulusi kuthamanga ndi kusamutsidwa kwa ulusi wamba. kuti chiwerengero cha kugubuduza chisinthiko si kwambiri, ngati kwambiri, dzuwa ndi otsika, pamwamba pa ulusi mano mosavuta kubala kulekana kapena osokonezeka buckle chodabwitsa. M'malo mwake, ngati chiwerengero cha zosintha ndi laling'ono kwambiri, ulusi m'mimba mwake n'zosavuta kutaya bwalo, kugubuduza kuthamanga zachilendo kuwonjezeka siteji oyambirira, chifukwa cha kufupikitsidwa ulusi moyo. buckle;Ulusi wachoka mozungulira.Ngati zolakwikazi zikuchitika mu Ziwerengero zazikulu, zidzapezeka mu gawo lokonzekera.Ngati chiwerengero chochepa cha zolakwikazi chikuchitika, ndondomeko yopangira sidzazindikira zolakwika izi zidzayenda kwa wogwiritsa ntchito, zomwe zimayambitsa mavuto.Choncho, nkhani zazikuluzikulu zogwirira ntchito ziyenera kufotokozedwa mwachidule kuti athe kulamulira zinthu zofunikazi pakupanga.
Zomangira zamphamvu kwambiri ziyenera kutenthedwa ndi kutenthedwa molingana ndi zofunikira zaukadaulo.Cholinga cha chithandizo cha kutentha ndi kutenthetsa ndikuwongolera makina omangira kuti akwaniritse mtengo wake wamphamvu komanso kupindika kwamphamvu. Choncho, kuti apange zomangira zapamwamba zamphamvu kwambiri, m'pofunika kukhala ndi zipangizo zamakono zopangira kutentha kwapamwamba. Chifukwa cha mphamvu zazikulu zopangira ndi mtengo wotsika wa ma bolts amphamvu kwambiri, komanso mawonekedwe abwino komanso olondola a ulusi wa wononga, zipangizo zochizira kutentha zimayenera kukhala ndi mphamvu zazikulu zopangira, digiri yapamwamba ya automation ndi khalidwe labwino la kutentha kwa kutentha. udindo waukulu.
