Kupu Whakataki
Te Mau o te Pin Boss: Te Aratau Rahunga o te Pūurutau Tino Noa
Ko te tumuaki pine te porotaka porotaka i runga i te urutau e haerehia ana e te pine raka hei pupuri i te niho. I roto i ngā huringa uta i roto i te rua kohatu, ina pā te peere ki te toka i te 0.5 ki te 1.2 mita ia hekona, ka pāngia te tumuaki pine e ngā kawenga kutikuti huringa o te 80 ki te 180 kN ia huringa. I muri i te 1,500 ki te 2,500 hāora o te mahi rua kohatu noa, ka taea e te diameter o te poka tumuaki te whakanui ake mā te 2.5 ki te 4.0 mm mai i te kakahu whakakoi, ka taea ai e te pine te neke i raro i te kawenga.
Kia neke te pine i te 3 mm, neke atu rānei, mai i tōna tūranga nohoanga, ka heke te pupuri niho ki te 40 ōrau o te hoahoa. Kātahi ka taea e te pine te haere atu i raro i te huringa kawenga-teitei e whai ake nei, ka tukuna te niho i waenganui o te keri. I inehia e tā mātou tīma whakarewa te kakahu o te pū whakapū i runga i te 47 o ngā urutau J300 i whakahokia mai, ā, i kitea ko ngā urutau i hangaia mai i te maitai koranu 30CrNiMo8 i tineihia ki te 42-46 HRC he 62 ōrau te iti iho o te kakahu o te pū i ngā urutau mai i te maitai waro 40Cr i te 35-39 HRC. Ko te hanganga koranu chromium-nickel-molybdenum ka ātete atu ki te whakauru matūriki whakakoi he tino whai hua ake i te maitai waro noa.
Te whati o te awaawa mowhiti pupuri
He maha ngā urutau J300 e whakamahi ana i tētahi mowhiti pupuri puna-utaina e piri ana ki roto i tētahi awaawa i te ihu urutau. Ka mahi te awaawa mowhiti hei whakaara ahotea kua mīhinihia ki roto i te āhua urutau. I roto i ngā keri toka pānga nui i te wā e neke atu ana ngā kaha teitei i te 250 kN, ka tīmata ngā kapiti moroiti i te pūtoro pakiaka o te awaawa i roto i te 300 ki te 500 hāora mahi. E whakaatu ana ngā raraunga mara mai i te 12 ngā keri toka mārō o Ahitereiria e 23 ōrau o ngā rahunga urutau J300 katoa i puta mai i te whati awaawa-ki-ihu, me te wehenga katoa o te niho i roto i te iti iho i te 50 hāora mai i te kapiti tuatahi ka kitea.
Ko tā mātou otinga he āhua awaawa kua whakarerekētia me te radius 1.5 mm i te pūtake (ki te radius paerewa 0.5 mm) me te pakeke o te mata 48-52 HRC mā te maimoatanga wera rerekē. Ka roa ake te tīmatanga o te pakaru ki tua atu i te 1,800 hāora i roto i ngā whakamātautau whakahaere. I roto i ngā āhuatanga o te rua keri, ka tūtohu mātou kia 25 hāora ngā wā tirotiro nā te mea ko te tere horapa o te pakaru i roto i te maitai 40Cr he 0.08 ki te 0.15 mm mō ia 100 huringa ina tīmatahia.Te haumaru o te ngeruE taunaki ana ngā tikanga kia tirotirohia te awaawa GET i ia 50 hāora, engari i roto i ngā mahi keri kohatu he poto ake te matapihi tīmatanga o te ngatata, ā, he tika te auau o te tirotiro nā te kaha o te putanga o te rahunga.
Te Pakaru o te Nohoanga Āpitihanga mai i te Pakaru o te Rohe e Pāngia ana e te Wera o te Weld
Ko te nohoanga urutau ko te mata poutū e pā ai te urutau ki te ngutu o te peere. I te wā e whakarewahia ana, ka taea e te rohe e pāngia ana e te wera i roto i te konganuku turanga urutau te eke ki te 725 ki te 850 nekehanga C, ka puta te whakakoi o te witi me te hanganga martensite i roto i ngā maitai waro-waenga. Ko ngā uara pānga Charpy o ēnei rohe HAZ he iti iho i te 8 ki te 12 J i te 20 nekehanga C, ki te whakaritea ki te 27 ki te 35 J mō te konganuku matua. Ina pāngia tēnei rohe pakarukaru e ngā wā piko huringa o te keri rua, ka tīmata he kapiti ngenge i te rohe HAZ ka horapa ki raro mā roto i te matotoru o te urutau.
Kāore e kitea te pakaru mai i waho nā te mea ka tīmata i te taha raro o te mata o te nohoanga. I roto i tētahi take kua tuhia mai i tētahi rua kōhatu o te UK, i kutikutia e tētahi keri 40-tana e mahi ana i te 85 ōrau o te rere waipēhi tētahi urutau J300 mā roto i te HAZ i muri i te 1,100 hāora o te ratonga me te kore he tohu tirohanga i mua. Hei whakakore i te pakaru o te HAZ, ka hangaia e mātou ngā urutau J300 mai i te maitai bainitic waro-iti (0.18-0.22 ōrau C, 0.8-1.2 ōrau Mn) e pupuri ana i ngā uara Charpy i runga ake i te 27 J ahakoa i muri i te whakaata i te 850 deg C. Mā te whakamahana i mua ki te 200-250 deg C i mua i te whakarewa me te whakamamae i te ahotea i muri i te whakarewa i te 300 deg C mō te 30 meneti ka whakaitihia te pakeke o te HAZ i raro iho i te 350 HV.
Te Wetekina o te Tikanga Maukati i raro i te Wiri Hurihuri
Ahakoa kei te mau tonu te hanganga ā-tinana, ka taea e te tikanga raka te wetekina i roto i te wā nā te wiri auau teitei. Ko te tātari wiri o ngā keri J300 i roto i ngā tono keri karāhe e whakaatu ana i ngā auau matua i waenga i te 15 me te 45 Hz i te wā pakaru o te huringa keri, me te kaha whakaterenga e eke ana ki te 5 ki te 8 karamu i te peere. I whakaatuhia e ngā inenga taipana i runga i ngā pūnaha raka momo-tīwiri J300 i heke te taipana tāutanga tuatahi o te 350 Nm ki te 180 Nm i muri i te 120 hāora whakahaere i roto i ngā āhuatanga keri maroke.
