He aha ngā Tikanga e Hōhonu ai i te Tika o te Tāwhai Aluminium?

Te Hoahoa Matatau Kua Whanaketia mō te Tika o te Tāwhai Aluminium

Te Whanaketanga Āhua mā te CAD/FEA hei Whakatōpoto i te Rere o te Mātā me te Tiki i ngā Tolerances

Ko te whiwhi i ngā totohu mātātoko karaka he mea nui rawa te āhua o ngā porowhita e whakamahia ana i te wā o te whakaputa. Ā, i ēnei rā, ko te nuinga o ngā mātai mātai e whakamahi ana i te pūmanawa CAD matatau hei waihanga i ngā tauira mātātoko o ngā āhua herenga me te pono tino pai. I te wā kotahi, ko ngā whakamātau FEA e āwhina ana i te tātai i te ara e pā ai ngā matēria kia pā ki ngā pēhitanga o ngā tikanga totohu. Ka whakaputangia e ngā kaiwhakaputa te wā ki te whakamātau ā-hāpori i ngā roa pae rerekē me ngā tautuhinga wāhi ki te tūhono, kia taea ai te kite i ngā raru e rere ana mua i te whakaputa i ngā tauira pū. Ka iti ake te tāwhai i te whakamātau takotoranga umanga 40%, ka pā ki te wā me te moni. He mea nui ake anō ko te eke ki ngā rahi tōtika i roto i te pae o te 0.1mm. Ko te pono o tēnei rākau he mea tino nui i ngā umanga pērā i te umanga rererangi me te umanga waka, kei hea anō ngā wehenga iti kaua e pā ki ngā whakaritenga ka taea ai te whai raru nui ake i muri ake.

Te Whiriwhiringa Matēria H-13, Te Tōmuri i te Roa Pae, me te Arataki i te Māmātanga Māmā

Kua tū a H13 hot work steel hei kōwhiringa mō ngā pēhi nā te pai ki te whakahaere i te mamae mā te wera, ā, ka mahi tika ki ngā wera e 500 ki te 550 neketa Celsia. Ka rerekē te roa o te pae e hāngai ana ki te herenga o te takotoranga, heoi anō e 2 ki te 8 mirimita. Kātahi ka taea te pupuri i ngā tere putake engari he aha te rerekē o te tino. Ko ngā ara whakakīhikihi i roto i te pēhi e pupuri ana i te wera, e noho ana i roto i te 5 neketa Celsia o te here. Ko tēnei whakahaere wera e pehi ana i te waru mā te 60% i ngā tikanga tawhito. Mō ngā kaihanga e whakahaere ana i ngā tinihanga nui, ko te tikanga he pai ake te tino ōrite o ngā wāhanga mai i te timatanga ki te mutunga.

Te Whakahaere Tukanga Ora-Moemoea i te Tāpiri Karaitina

Te Whakahaere Tāpoi me te Whakahaere Pēhi tru ngā Mātai Tau Tara

Ko ngā kairākau e tohua ana i te tōtika o te pūnaha e arotake ana i ngā wera o ngā ingoa me te toto during extrusion, ka tuku i ā rātou korero ki tētahi pūnaha whakahaere e hāngai ana i te wā. Ina piki ake, heke iho rānei ngā wera i te 5 nekenga Celsius, ina piki ake te toto i te 50 bar, ka whakauru tonu te pūnaha hei whakatika i ngā mea i mua i te putanga o ngā raru. Ka arahina ēnei momo raruraru ki ngā pakaru o te mata, ngā raina horapa e kitea ana, me ērā atu whakararuraru o roto e hiahia ana mātou kia wāwāhi. Ko te āhua o te whakahaere i te katoa i te wā pono e āwhina ana te rere o te paraihe i te pūnaha, ā, e pupuri ana i te tōwātanga o ngā rahi. E ai ki ētahi rangahau a te ahumahi mō te uara o te extrusion, kua kitea e ngā kaihanga i te heke haere o te reiti kapi tata ki te 18% nā ngā pūnaha arotake pēnei.

Ngā Kōtuitanga Whakakaha Āhuatanga mō te Whakamaroke Kotahi me te Tōpūtanga o ngā Rahi

Ko te whakākau i muri i te tāpore e noho ana he roa matua nui ki te whakarite i ngā āhuatanga kaha o te matēria me te pupuri i te āhua e hiahiatia ana. Ko ngā pūnaha whakākau āki-āki anō hou e here ana i te paraire wai me te hau ake pea i te wā e neke ana te ahunga puta noa i te rohe whakākau. Ka utu ēnei pūnaha mō ngā rerekētanga o te tino nekenga o te waewae i runga i te hua. Ina arotake ana ki ngā wāhanga tino, ka pakari ake te whakākau kia pērā rite te uaua o ēnei wāhi ki ngā wāhanga māmaieka e tata ana. Kātahi ka aukati tēnei whakahaere tūmatakura i ngā rerekētanga e kore e hiahiatia ana, ā, ka pupuri i ngā rahi ki roto i ngā wherewherenga tere ±0.1mm. Mō ngā kaihanga e hanga ana i ngā wāhanga tikangia e whakamahia ana ki ngā inihini rererangi, ki ngā tarairanga motokā rānei, e nui ana te take o ngā rerekētanga iti, ko te rāwekenga o te whakahaere tēnei e matua here ana ki te tutuki i ngā paunatanga kounga, ā, ki te aukati i te mahi anō e nui ana te utu.

Te Tiaki Kounga Kotahi mō te Tikanga Tāpore Hiriwa

Tātai Puna Wherewherenga: Ngā Paunatanga AA vs. Te Tikanga E Taea ana i te Ao Tūmatanui

Ka whakaatu te Tiamara Taraiwa mā hea e mea ana kia mahi me ngā whākahuatanga āhuatanga teoritikally, engari ina tata ana ki te hanga pūmahara, ka tere haere ngā mea. Ka taea e te nekeneke o te wera, ngā pāpā kua pāhua, me ngā matērihi e kore e tino rite ana te nui ake i te tohu 0.1mm i ngā huinga hanga nui. Kāore ngā whare hanga mātai ka whakapono anake ki ngā whakaritenga AA engari ka mātai i te mea e pā ana ki te kaipuni. Ka whakauru i aua tau whaimana ki ngā mea e hanga ana tō rātou māhine i ia rā. Ko te whai i ngā paerewa ā-ao pērā i te ISO 2768 me te ASTM B221 ka āwhina ki te pupuri i te tikanga kotahi i waenganui i ngā whare hanga rerekē anō hoki. Ko te mea e mahi pai ana mō te nuinga o ngā toa ko te taurite i waenganui i te mea e taea ana hanga me te mea e hāngai ana ki te āhuatanga ōhanga. Ka pupuri tēnei i ngā mātai e hoahoa ana i ngā wāhanga e hāngai ana, ka iti ake te matērihi kua pau, me te penapena moni mā te whakakaha i te aro nō te wāhi e hiahiatia ana anō hoki ki te hua whakamutunga.

Te Tātai Ā-Rārangi me te Aronga Whakahaere Tauira (SPC) Whakaurunga

Ko ngā punaha tātai i roto, tae atu ki ngā kātata rīwhi me ngā mīhini ine tauwāhi e āki ai ngā inenga o te wā tonu ake pea ka whakaputangia ngā matū. Ka āwhina i ngā kaihanga kia mataara ki ngā āhuatanga nui pērā i ngā rahi o te wera, ngā panonitanga o te toki, me te tere o te ram kei te nekeneke i te matū te whakauru i ēnei ki te Tari Whakahaere Tūmatanui, te SPC rānei. Ko te take katoa he pakaru i ngā raruraru i mua i te putanga ake o ngā ririhau. Ko te mataara tonu e pupuri ana i te aronga kia pai, e iti ake ai ngā hua kino, ā, he iti ake ngā whakatikatika e hiahiatia ana i muri i te timatanga o te whakaputa. Mō ngā toihanga e hāngai ana ki te hanga i ngā wāhanga tik-puta, ka penapena tēnei ara i te wā me te moni i te tini.

Whakapai Pūnga Kiko hei Tautoko i te Tik-puta o te Whakaputanga Karawhiti

He nui te take o te tika o ngā tikanga upstream i te wā e hangaia ana ngā wāhanga tikangia. Ko te whakaritenga i ngā billet, te whakahaere i ngā wāhi mātātoko, me te tautapa i ngā pēhi extrusion he wāhanga matua nui ki te kounga o te hua mutunga. Ka pakaru te tika o te āhua ina kāore ngā billet e ōrite ana te kounga. Nō reira ko te tirotiro i ngā huinga horoi tino pai, me te whakahaere i ngā maimoatanga homogenization tika he mea nui i mua i te extrusion. Mā te pupuri i ngā wāhi ki roto i te paku nei, rite ki te ±5°C i te wā o te whakapiri ka arrengia ngā raru rere e āhua pakaru ai te hua mutunga. Kei te whai ngā taputapu extrusion hou anō i ngā here tino pai ake e hāngai ana i ngā tere ram ki ngā tautuhinga toki, e iti ake ai ngā rerekētanga o te tini o ngā pāpā ki raro i te 0.1 mirimita i te nuinga o te wā. Ka taea e ngā kaihanga te toro ki ngā raraunga extrusion o mua mā ngā taputapu AI hei timata atu ki te rapu i ngā tautuhinga tino pai mō ngā kōrahi hou, e iti ake ai te maha o ngā whakamātautau e hiahia ana kia mahia. Ko te whakauru i te Statistical Process Control (SPC) i te tīmatanga o te whakaputa e iti ake ai ngā hapa downstream umanga 30 ki te 40%. Heoi anō, ka mea ngā tohunga kei te nuinga o ngā raru āhua mai i ngā raruraru i tīmata noa i ēnei mahi upstream.
