I roto i te hanga mekameka roera, he tukanga nui te whakarewa hei hono i ngā hononga me te whakarite i te kaha o te mekameka. Heoi, ko te whakarerekētanga wera i te wā whakarewa ka noho hei raruraru pumau, ka pā ki te tika me te mahi o te hua.mekameka roeraka puta pea ngā raruraru pēnei i te piko o te hononga, te koretake o te papatahi, me te koretake o te kukū o te mekameka. Ehara i te mea ka whakaiti noa i te pai o te tuku engari ka whakanui ake i te kakahu, ka whakapoto i te roa o te mahi, ā, ka raru pea ngā taputapu. Hei taputapu matua mō te whakahaere i te whakarerekētanga, ko te hoahoa o ngā taputapu whakarewa te mea e whakatau tika ana i te kounga o te whakarewa mekameka roera. Ka tirohia e tēnei tuhinga ngā pūtake o te whakarerekētanga o te whakarewa mekameka roera, ā, ka whakamāramahia hoki me pēhea te whakatutuki i te whakahaere whakarerekētanga mā te hoahoa taputapu pūtaiao, me te whakarato i ngā otinga hangarau whai hua mō ngā kaimahi hanga.
Tuatahi, kia mārama: He aha te pūtake o te whakarerekētanga o te mekameka roera?
I mua i te hoahoa i tētahi taputapu, me mārama tuatahi tātou ki te take matua o te whakarerekētanga o te mekameka roera—te tukunga ahotea i puta mai i te whakaurunga wera koretake me te kore e taea te pupuri. Ko ngā hononga mekameka roera he mea hanga i ngā pereti o waho me o roto, ngā pine, me ngā pū. I te wā e whakarewa ana, ka whakamahia te whakamahana ā-rohe ki te hononga i waenga i ngā pereti, ngā pine, me ngā pū. Ko ngā take matua o te whakarerekētanga i roto i tēnei tukanga ka taea te whakarāpopoto penei:
Te tohatoha taumahatanga wera kore taurite: Ko te pāmahana teitei e puta mai ana i te pewa whakarewa ka tere te horapa o te konganuku i te rohe, ko ngā wāhi kāore i werahia e karapoti ana, nā te iti o te pāmahana me te pakari ake, ka mahi hei aukati, ka aukati i te konganuku wera kia kore e horapa noa, ka puta he taumahatanga pēhi. I te wā whakamatao, ka whakawhāiti te konganuku wera, ka āraihia e ngā wāhi e karapoti ana, ka hua ake he taumahatanga kume. Ina nui ake te taumahatanga i te pūwāhi tuku o te rauemi, ka puta he whakarerekētanga tuturu, pērā i ngā hononga piko me ngā pine kāore i te tika te tūnga.
Te koretake o te tika o te tūnga o ngā wāhanga: Ko te piko o te mekameka roera me te whakarara o te hononga he tohu matua mō te tika. Mena kāore i te mārama te tohutoro tūnga o ngā wāhanga i roto i te taputapu i mua i te whakarewatanga, ā, he koretake te kaha o te piri, ka ngāwari ngā wāhanga ki te hē o te taha, te roa rānei i raro i te mahi a te ahotea wera i te wā whakarewatanga, ka puta he rerekētanga o te piko me te hē o te hononga. Te kore hototahi i waenga i te raupapa whakarewatanga me te taputapu: Ka taea e te raupapa whakarewatanga hē te whakaemi wera i roto i te mea mahi, ka nui ake te rerekētanga ā-rohe. Mena ka kore te taputapu e whakarato i ngā here hihiri i runga i te raupapa whakarewatanga, ka nui ake te rerekētanga.
Tuarua, ko ngā mātāpono matua o te hoahoa o ngā taputapu whakarewa: te tūnga tika, te piri pumau, me te ngawari o te marara wera.
I runga i ngā āhuatanga hanganga o ngā mekameka roera (ngā wāhanga maha me ngā pereti mekameka angiangi, ngāwari te whakapōturi) me ngā whakaritenga whakarewa, me piri te hoahoa o te taputapu ki ngā mātāpono matua e toru hei whakahaere i te whakapōturi i te pūtake:
1. Te Mātāpono Raraunga Kotahi: Te Whakamahi i ngā Tohu Tika Matua hei Raraunga Tūnga
Ko te tino tika o ngā mekameka roera ko te tika o te piko me te whakarara o te pereti mekameka, nō reira me aro te hoahoa tūnga o ngā taura ki ēnei tohu e rua. E taunakihia ana te tikanga tūnga "kotahi-papa, rua-pine" matarohia: ko te mata papatahi o te pereti mekameka te mata tūnga tuatahi (e whakawhāiti ana i ngā nekehanga herekore e toru), ā, mā ngā pine tūnga e rua, e hono ana ki ngā kōhao pine (e whakawhāiti ana i ngā nekehanga herekore e rua me te kotahi), ka tutuki te tūnga katoa. Me hanga ngā pine tūnga ki te maitai koranu ātete-kakahu (pērā i te Cr12MoV) me te tinei (pakeke ≥ HRC58) kia mau tonu ai te tika o te tūnga ahakoa te whakamahinga roa. Me pupuri te tawhiti i waenga i ngā pine tūnga me ngā kōhao pine pereti mekameka i waenga i te 0.02-0.05mm hei whakahaere i te whakapiri me te ārai i te nekehanga o ngā wāhanga i te wā whakarewa.
2. Te Mātāpono Whakarerekētanga o te Kaha Whakapūmau: "He Rawaka, ā, Kore e Kino"
He mea nui te hoahoa o te kaha piri hei whakataurite i te aukati i te whakarerekētanga me te aukati i te kino. Ka taea e te kaha piri nui te whakarerekētanga kirihou o te pereti mekameka, engari ka taea e te iti rawa te aukati i te ahotea whakarewa. Me tutuki ēnei whakaaro hoahoa:
Me whakanoho tika te pūwāhi whakapiri: tata ki te wāhi whakarewa (≤20mm mai i te whakarewa) me te whakanoho ki tētahi wāhi pakari o te pereti mekameka (pērā i te taha o te kōhao titi) kia kore ai e piko nā te kaha whakapiri e mahi ana i waenganui o te pereti mekameka. Kaha Piri Whakarerekē: Kōwhiria te tikanga whakapiri tika i runga i te matotoru o te mekameka (te nuinga o te 3-8mm) me te rauemi (te nuinga he maitai hanganga koranu pērā i te 20Mn me te 40MnB). Kei roto i ēnei tikanga ko te whakapiri hau (he pai mō te hanga papatipu, me te kaha whakapiri ka taea te whakarerekē mā te kaiwhakahaere pēhanga, mai i te 5-15N) te whakapiri tīwiri rānei (he pai mō te whakaritenga iti-rōpū, me te kaha whakapiri pumau).
Te Pa Whakapiri Ngāwari: Ka tāpirihia he gasket polyurethane (2-3mm te matotoru) ki te wāhi pa i waenga i te poraka whakapiri me te mekameka. Ka whakanui ake tēnei i te waku, ā, ka ārai i te poraka whakapiri kei kōkuhu, kei rakuraku rānei i te mata o te mekameka.
3. Te Kaupapa Whakakotahitanga o te Wera: Te Whakataurite Wera i waenganui i te Rawhi me te Tukanga Whakarewa
Ko te āhua o te whakarerekētanga o te whakarewa he mea nui nā te tohatoha wera kore taurite. Nō reira, me whakarato te rawhi i te tohatoha wera āwhina, me te whakaiti i te ahotea wera mā te huarahi rua o te "tohatoha wera kaha me te kawe wera kore." Mō te kawe wera kore, me hanga te tinana o te taputapu ki tētahi rauemi he kawe wera teitei, pērā i te koranu konumohe (kawe wera 202W/(m・K)) te koranu parahi rānei (kawe wera 380W/(m・K)), hei whakakapi i te rino maka tuku iho (kawe wera 45W/(m・K)). Mā tēnei ka tere ake te kawe wera i roto i te wāhi whakarewa. Mō te tohatoha wera kaha, ka taea te hoahoa i ngā awa wai whakamatao tata ki te whakarewa o te taputapu, ā, ka taea te whakauru i te wai whakamatao e rere ana (te pāmahana wai e whakahaeretia ana i te 20-25°C) hei tango i te wera ā-rohe mā te whakawhiti wera, kia ōrite ake ai te whakamatao o te wāhanga mahi.
Tuatoru, Ngā Rautaki Matua me ngā Taipitopito i roto i te Hoahoa Rawhi hei Whakaiti i te Hurihanga o te Mekameka Roera
I runga i ngā mātāpono o runga ake nei, me arotahi tā tātou hoahoa ki ngā hanganga me ngā mahi motuhake. Ka taea te whakamahi tika i ngā rautaki e whā e whai ake nei i roto i te mahi whakaputa tūturu:
1. Hanganga Tūnga Āhuahira: Ka taea te whakarerekē ki ngā Whakatakotoranga Mekameka Roera Maha, kia rite ai te Tūnga
He maha ngā whakaritenga o ngā mekameka roera (hei tauira, 08A, 10A, 12A, me ētahi atu, me ngā koki mai i te 12.7mm ki te 19.05mm). Mā te hoahoa i tētahi taputapu motuhake mō ia whakaritenga ka piki ake ngā utu me te wā whakawhiti. Ka tūtohu mātou kia whakamahia ngā wāhanga whakanoho taupū: Kua hangaia ngā pine me ngā poraka whakanoho kia taea te whakakapi me te hono atu ki te turanga taputapu mā roto i ngā pūtu. Ina huri ana i ngā whakaritenga, tangohia noa te wāhanga whakanoho tawhito ka tāuta i tētahi mea hou me te koki e rite ana, ka whakaitihia te wā whakawhiti ki raro iho i te 5 meneti.

2. Hoahoa Here Ā-taurite: Te Whakakore i te "Taunekeneke" o te Taumahatanga Whakarewa
He maha ngā hanganga ōrite i roto i te whakarewa mekameka roera (hei tauira, te whakarewa i te pine ki te pereti mekameka takirua i te wā kotahi). Nō reira, me whakamahi te taputapu i tētahi hoahoa here ōrite hei whakaiti i te rerekētanga mā te whakakore i ngā ahotea. Hei tauira, i te wā o te tukanga whakarewa o te pereti mekameka takirua me te pine, me whakanoho te taputapu kia ōrite ki ngā poraka whakanoho me ngā taputapu whakapiri i ngā taha e rua o te mekameka hei whakarite i te urunga wera whakarewa me te kaha aukati. Hei tāpiri, ka taea te whakanoho i tētahi poraka tautoko āwhina ki waenganui o te mekameka, kia ōrite ki te papa o ngā pereti mekameka, hei whakaiti i te ahotea piko i waenganui i te wā whakarewa. E whakaatu ana ngā raraunga mahi ka taea e te hoahoa here ōrite te whakaiti i te rerekētanga o te pitch i roto i ngā mekameka roera mā te 30%-40%.
3. Te Whakapiripiri Whai-ake Hihiri: Te Urutau ki te Hurihanga Wera i te Wā Whakarewa
I te wā e whakarewa ana, ka nekehia te mea mahi kia iti rawa ngā nekehanga nā te whānui me te whakahekenga o te wera. Mā te tikanga whakapiri pumau ka hua ake he kukū ahotea. Nō reira, ka taea te hoahoa i te taputapu me tētahi tikanga whakapiri hihiri: ka aroturukihia e tētahi pūoko nekehanga (pērā i te pūoko nekehanga taiaho me te tika o te 0.001mm) te whakarerekētanga o te pereti mekameka i te wā tūturu, ka tukuna te tohu ki te pūnaha whakahaere PLC. Kātahi ka peia e te motuka servo te poraka whakapiri mō ngā whakatikatika moroiti (me te whānuitanga whakarerekētanga o te 0-0.5mm) kia mau tonu ai te kaha whakapiri tika. He tino pai tēnei hoahoa mō te whakarewa i ngā mekameka roera pereti matotoru (matotoru ≥ 6mm), ka ārai pai i te pakaru o te mekameka i puta mai i te whakarerekētanga wera.
4. Te Ārai i te Whakarewa me te Hoahoa Arataki: Ka Whakarite i te Ara Whakarewa Tika, ka Whakaiti i te Rohe e Pāngia ana e te Wera
I te wā e whakarewa ana, ka pā tika te tika o te ara nekehanga o te pū whakarewa ki te kounga whakarewa me te urunga wera. Me whai awaawa ārai hononga whakarewa me te arataki pū whakarewa te taputapu.

Hei tāpiri, me tāuta he arataki arataki ki runga ake i te taputapu hei whakarite i te nekehanga ōrite o te pū whakarewa i te ara kua whakaritea (e taunakihia ana kia 80-120mm/min te tere whakarewa), kia tika ai te whakarewa me te urunga wera ōrite. Ka taea hoki te whakanoho i te rauemi whakamarumaru uku ki roto i te awaawa ārai hei ārai i te pakaru o te taputapu mai i te tauhiuhi whakarewa.
Tuawhā, Te Arotau me te Manatoko i ngā Tauira: Te Mana Whakahaere Porowhita-Katia mai i te Hoahoa ki te Whakatinanatanga
Me arotake me te manatoko te hoahoa pai i mua i te whakatinanatanga pono. Mā ngā mahi e toru e whai ake nei ka taea te whakarite i te whai huatanga me te pono o te taputapu:
1. Tātaritanga Whakatakotoranga Huānga Mutunga Kore: Te Matapae i te Hurihanga me te Arotau i te Hanganga
I mua i te hanganga o te taputapu, ka whakahaerehia ngā whakatauira hononga wera-hanganga mā te whakamahi i ngā pūmanawa huānga mutunga kore pēnei i a ANSYS me ABAQUS. Mā te whakauru i ngā tawhā rauemi mekameka roera (pēnei i te tauwehenga whānui wera me te modulus elastic) me ngā tawhā tukanga whakarewa (pēnei i te ia whakarewa o te 180-220A me te ngaohiko o te 22-26V) ka whakatauira i te tohatoha pāmahana me te ahotea i roto i te taputapu me te wāhanga mahi i te wā whakarewa, ka matapae i ngā wāhi whakarerekētanga pea. Hei tauira, mēnā ka whakaatuhia e te whakatauira he nui rawa te whakarerekētanga piko i waenganui o te pereti mekameka, ka taea te tāpiri tautoko atu ki te wāhi e rite ana i roto i te taputapu. Mēnā ka puta te kukū ahotea ki te pine tauwāhi, ka taea te arotau i te radius o te pine (e taunakihia ana a R2-R3). Ka taea e te arotautanga whakatauira te whakaiti i ngā utu whakamātautau-me-te-hapa o te taputapu me te whakapoto i te huringa whanaketanga.
2. Manatoko Whakamātautau Whakarewa: Whakamātautau Puranga-Iti me ngā Whakatikatika Auau
Kia oti te hanga o te taputapu, whakahaerehia he whakamātautau iti mō te manatoko i te whakarewa (e taunakitia ana: 50-100 ngā wahi). Arotahi ki ngā tohu e whai ake nei:
Te Tika: Whakamahia he karuārai whānui hei ine i te pekapeka o te tohu (me ≤0.1mm) me te whakarara o te pereti mekameka (me ≤0.05mm);
Te Hurihanga: Whakamahia he mīhini ine taunga hei matawai i te papatahi o te pereti mekameka, ka whakatairite i te huringa i mua me muri i te whakarewanga;
