I. Te Hiranga o te Kōwhiri i ngā Mekameka me ngā Herehere Tika
I roto i ngā wheketere sima, he mea tino nui ngā ararewa peere mō te kawe poutū i ngā rauemi taumaha, koi pērā i te clinker, te pākeho kōhatu, me te sima.Ngā mekameka me ngā here porowhitaka pāngia e te ahotea miihini nui, ā, he mea nui te whakahaere kounga o ā rātou hoahoa me te whakaputa mō te angitu o te mahi. Anei te take he mea nui te whiriwhiri i ngā wāhanga tika me te huarahi e aro atu ai a SCIC ki tēnei:
1. Te Kaha Whakamau Utaina:Ngā mekameka me ngā hereme tu atu ki ngā kawenga kume teitei me ngā pānga ru mai i te nekehanga tonu o te peere. Ka tūpono ngā wāhanga iti iho i te paerewa ki te pakaru ohorere, ka arahi ki te wā kore mahi, ngā tūponotanga haumaru, me ngā whakatikatika utu nui. Mā te piripono o SCIC ki ngā paerewa DIN ka whakarite kia tutuki i ā mātou hua ngā whakaritenga kaha e tika ana, pērā i te kaha pakaru kua tohua o te 280–300 N/mm².
2. Ātete ki te Pakaru: Ko te āhua whakakoi o ngā rauemi sima ka tere ake te pakaru o ngā wāhanga ararewa. Ko ngā mekameka whakapakeke-kiri (tae atu ki te 800 HV) me ngā here (tae atu ki te 600 HV) ka whakarato i tētahi mata pakari hei ātete i te pakaru, me te pupuri tonu i te pakari o te matua hei ārai i te pakaru. Mā te tukanga whakakoi tika a SCIC ka tutuki te matotoru whakakoi 10% e hiahiatia ana me te hohonutanga pakari whai hua 5–6%, kia roa ai te mahi.
3. Te Whakatutuki i ngā Paerewa: Mā te whakatutukitanga i ngā paerewa DIN 764, DIN 766, DIN 745, me te DIN 5699 ka whakamanahiamekameka me ngā heretutuki i ngā paearu ahumahi mō ngā ine, ngā āhuatanga rauemi, me te pono. Mā te tohungatanga o SCIC ki te tutuki i ēnei paerewa ka whakarite kia rite te kounga ki ngā tono taumaha.
4. Te Mana Whakahaere Kounga Whakaputa: Mā te mana whakahaere kounga pakari a SCIC—mai i te kōwhiringa rauemi ki te tirotiro whakamutunga—ka whakaitihia ngā hapa, ā, ka whakarite i te tika o ngā āhuatanga, te pakeke, me te kaha. Mā tēnei āheinga ka whakaitihia te tūponotanga o ngā rahunga i raro i ngā āhuatanga uaua o ngā wheketere sima.
Te whiriwhiri i te tikamekameka me ngā hereHe mea nui tēnei mō te whai huatanga me te haumaru o ō ararewa peere. I SCIC, kua hoahoatia, kua hangaia hoki ā mātou hua kia tutuki ai ngā paerewa DIN pakari, kia taea ai e rātou te tu atu ki ngā kawenga taumaha me ngā rauemi whakakoi e kitea ana i roto i ngā wheketere sima. Mā ā mātou mana whakahaere kounga pakari, ka taea e koe te whakawhirinaki ka whakarato ā mātou mekameka me ngā here i te mahi pono, ka whakaiti i te tūponotanga o ngā pakaru ohorere me ngā utu tiaki.
II. Te Whakataurite i te Pakari me te Kaha i te Wā Hanga
Hei whakatutuki i te pakeketanga o te mata kua tohua e te kiritaki (800 HV mō ngā mekameka, 600 HV mō ngā here), te matotoru o te whakapūkara (10% o te diameter o te hononga), te hohonutanga o te pakeketanga whai hua (550 HV i te 5–6% o te diameter), me te kaha whati (280–300 N/mm²) me whai taurite tupato i waenga i te pakeketanga me te kaha. Anei te huarahi e tutuki ai tēnei e SCIC mā te whiriwhiri rauemi, te maimoatanga wera, me te whakapūkara:
Ngā Tukanga Hanga Matua
1. Kōwhiringa Rauemi:Ka whiriwhiria ngā maitai waro-tiketike, ngā maitai koranu rānei nā te mea ka taea te aro ki te whakakākahu me te tinei, ka puta ai te mārō o te mata me te pakari o te matua.
2. Te whakakākahu:Mā te whakakāpūnga ka horahia te waro ki roto i te mata maitai hei whakanui ake i te pakeketanga. Mō te hononga mekameka he 20 mm te whānui;Te Hōhonutanga o te Whakapūngao: 10% o te 20 mm = 2 mm;Te Hōhonutanga o te Mārō Whai Hua: 5–6% o te 20 mm = 1–1.2 mm i te 550 HV;Ka hangaia he mata mārō, ātete ki te kakahu, me te pupuri tonu i te matua ngāwari hei ngongo i ngā kawenga hihiri.
3. Te Maimoatanga Wera:Te tinei: Whai muri i te whakakāpura, ka tineihia ngā wāhanga hei pupuri i te pakeke o te mata (800 HV mō ngā mekameka, 600 HV mō ngā here);Te Whakamahana: Mā te whakamahana whakahaere (hei tauira, i te 200–250°C) ka whakatikatika i ngā āhuatanga o te matua, kia pakari ai, kia rite hoki ki te kaha pakaru e hiahiatia ana o te 280–300 N/mm². Ka whakaitihia te pakeke e te whakamahana nui, engari ka pāngia e te pakarukaru e te whakamahana iti.
4. Ture Whakataurite: Pakeke: Ka ātete te pakari o te mata i te pakaru mai i ngā rauemi whakakoi;Kaha: Mā te pakari o te pūtake ka ārai i ngā pakarukaru i raro i ngā kawenga kume.Mā te SCIC e whakahaere te hohonutanga o te whakapūkara me ngā tawhā whakamahana hei karo i te pakarukaru nui, me te whakatutuki hoki i ngā whakaritenga a te kiritaki.
(ngā hononga mekameka me te pakeke teitei o te mata kua whakakākahuria)
(ngā hononga mekameka me te pakeke o te mata kua whakakākahuria, whai muri i te whakamātautau kaha pakaru)
Ka tino whakahaerehia tā mātou tukanga hanga kia tutuki ai te taurite tino pai i waenga i te pakeketanga me te kaha. Mā te whakakāpū me te whakamahana tika, ka whakarite mātou kiamekameka me ngā herehe mata mārō, ātete ki te pakaru, me te pupuri tonu i te matua pakari hei whakahaere i ngā kawenga hihiri i roto i āu mahi. He mea nui tēnei taurite hei whakanui ake i te roa o te ora me te pono o ngā taputapu.
III. Te Whakapūmau i te Roa o te Ora mā te Whakahaere me te Tiaki
Ahakoa mengā mekameka me ngā here kounga teitei, he mea nui te whakahaere tika me te tiaki kia roa ai te ora o ngā ararewa peere o te wheketere sima. Ka whakaratohia e SCIC ngā aratohu e whai ake nei ki ngā kiritaki:
Ngā Aratohu Tiaki
1. Ngā Tirotiro Auau:Tirohiamekameka me ngā heremō ngā tohu pakaru, pērā i te roanga (hei tauira, >2–3% o te roa taketake), te whakarerekētanga āhua, ngā pakaru mata rānei. Mā te kitenga wawe ka ārai i ngā rahunga.
2. Whakahinuhinu:Tāpirihia he hinu whakahinuhinu pāmahana teitei, taumaha hoki hei whakaiti i te waku me te pakaru. Whakahinuhinuhia ia 100–200 hāora mahi, i runga i ngā āhuatanga.
3. Te Aroturuki i te Taumahatanga:Kia mau tonu te kukū pai o te mekameka kia kore ai e ngenge rawa (e pā ai te oho) e tino kukū rānei (e piki ake ai te pakaru). Whakarerekētia kia rite ki ngā whakaritenga a te SCIC.
4. Whakakapinga i te Wā:Whakakapia tonutia ngā wāhanga kua tawhito, kua pakaru rānei, kia kore ai e pakaru haere. Hei tauira, me whakawhiti tonu i tētahi here kua pakaru.
5. Ngā Tikanga Pai mō te Whakahaere:Whakahaerehia i roto i ngā rohe hoahoa (hei tauira, karohia te taumaha rawa atu i te kaha pakaru 280–300 N/mm²) hei whakaiti i te ahotea.
Hei whakanui ake i te roa o te ora o ō mekameka me ō here, whai i ēnei tikanga: tirohia tonutia mēnā he pakaru, kia tika te whakahinuhinu, aroturukihia te taumahatanga o te mekameka, ā, whakakapia wawetia ngā wāhanga kua pakaru. Mā te piri ki ēnei aratohu me te whakahaere i roto i ngā rohe hoahoa, ka taea e koe te whakawhānui ake i te pono me te whai huatanga o ō ararewa peere.
Akoranga Take: Pānga o te Ao Tūturu
Horopaki:
I pāngia tētahi wheketere sima e te maha o ngā pakaru o ngā miro mekameka hono porowhita, ā, 10 hāora te wā e kore ai e mahi ia marama nā te mea he 600 HV noa iho te pakeke o ngā mekameka, he papaku hoki te hōhonutanga o te whakapūkara. Nā tēnei i nui ai ngā utu whakatika, ā, i ngaro ai te mahi whakaputa.
Otinga:
I tangohia e te wheketere ngā mekameka hononga porowhita whakapakeke a SCIC:
- Ngā tawhā: te whānui 30mm, te pakeke o te mata 800 HV, te hōhonutanga o te whakapūkara 3mm, te pakeke whai hua 1.8mm i te 550 HV, te kaha pakaru 290 N/mm².
- Tiaki: Arotakenga ia rua wiki, whakahinuhinu i ia 150 hāora, me ngā whakatikatika kume.
(ngā hononga mekameka me te hohonutanga whakapūkara kua whakapaitia ki te 10% te whānui o te hononga)
IV. Ngā Hua
1. Wā Whakamutu: Kua whakaitihia mā te 80% (ki te 2 hāora/marama).
2. Te Roanga Ora: Tekau mā waru marama te roa o ngā mekameka (ki tā te 6 marama o mua).
3. Te Penapena Utu: Kua heke ngā utu tiaki mā te 50% ia tau.
E whakaatu ana tēnei i te hua o ngā painga tūturu mai i ngā wāhanga kounga teitei a SCIC me ngā aratohu tiaki.
V. Whakamutunga
1. Te Kōwhiri i ngā Wāhanga Tika:Ngā mekameka me ngā here a te SCIC e tutuki ana i ngā whakaritenga DIN, e tautokona ana e te hoahoa tino pai me te mana whakahaere kounga, e whakarite ana i te haumaru me te whai huatanga i roto i ngā ararewa peere o te wheketere sima.
2. Te Whakataurite i te Pakari me te Kaha: Ka tutuki ā mātou tukanga hanga tika i ngā whakaritenga a te kiritaki, ka puta he ātete ki te kakahu me te kaha ki te pikau kawenga.
3. Te Whakanui i te Roa o te Ora: Mā ngā aratohu tiaki whai hua ka pono te mahi mō te wā roa.
Mā te mahi tahi me SCIC, ka whiwhi ngā kiritaki i te urunga atu ki ngā mekameka me ngā here i hangaia e te tohunga, i whakaritea kia rite ki ō rātou hiahia, ā, e tautokona ana e ngā rautaki kua whakamātauhia hei whakarei ake i te mahi me te whakaiti i ngā utu.
