Ahakoa te āhua māmā noa iho o ngā wāhanga tapawhā me ngā tapawhā whāiti, he maha ngā āhuatanga hangarau e pā ana ki tō rātou kaha me te mahi. Ko tētahi o ngā āhuatanga tino warewarehia engari he mea nui ko teKoki R, e mōhiotia ana ko te pūtoro kokonga. He mahi nui tāna ki te hanga kounga, te whanonga whakarewa, te mahi kawenga, te piri o te paninga, me te āhua tirohanga.
E whakamārama ana tēnei tuhinga he aha te koki R, me pēhea te tautuhi a ngā paerewa matua i tōna koki, me pēhea te ine, me ngā mea me aro atu e ngā kaihoko ina whiriwhiri ana i ngā ngongo.
He aha te koki R?
Ko te koki R e pā ana ki tete pūtoro o te pewa kokonga o wahoo te maitai tapawhā, tapawhā rāneipaipa.
Engari i te taha koi 90-tohu, ka hangaia te kokonga hei piko porowhita i te wā e whakairohia ana, e tāwhanahia ana rānei.
Ka pā ki:
Te mahi hanganga
Āheitanga whakarewa
Ataahua
Te tohatoha matotoru o te paninga
Te whakaurunga hononga me te mana whakahaere manawanui
Ahakoa te āhua iti, ka pā tika te whānui o te kokonga ki ngā hua hangarau.
Ngā Whakaritenga Koki R i raro i ngā Paerewa Ahumahi Noa
He rerekē te tautuhi a ngā rohe me ngā paerewa i te manawanui ki te koki R.
Anei tētahi tohutoro māmā ake:
◎ Paerewa Hainamana (GB/T 3094, GB/T 6728)
Ko te whānui o te kokonga kei waenganui i te1.5 × te matotoru o te pakitara ki te 3 × te matotoru o te pakitara
Ka taea e ētahi tonoiti rawa R ≥ 2mm
◎ Paerewa Pākehā EN10210 (Hanga Wera)
Te ātete matotoru pakitara teitei ake me te radius nui ake
Koki R noa ≈2 × matotoru o te pakitara, engari ka tae pea ki2.5 ×, 3 × rāneimō ngā wāhanga nui
◎ EN10219 (Whakaahua Matao)
He iti ake te radius e pā ana ki te EN10210
R noa ≥1.5 × te matotoru o te pakitara
◎ Paerewa Piritana BS EN10219 / BS 4360
E tino rite ana ki ngā whakaritenga EN10219
He aro nui ake ki te ōritetanga o te āhua kokonga me ngā rohe peka ke
◎ Paerewa Hapanihi JIS G3466
Te tautuhi i te koki R hei huri noa1.2 × ki te 2.0 × te matotoru o te pakitara
E mōhiotia ana mō te whakahaere i ngā āhuatanga tino pakari
✔ In ngā tono tūturu, kāore te pūtoro kokonga i te pumau; he rerekēe hangai anaon tehangarau hanga, taputapungā āhuatanga, ā, i whakaarohiawhakamahi.
✔ Te Hangangā manawanui i ngā wā maharerekē i waenga i ngā momo rerekēkaiwhakaratos.
Tohutoro Tātai me te Tikanga Ine
Tātai Whakatau Tatau Koki R (Ture Ahumahi):
R ≈ 1.5–3.0 × matotoru o te pakitara (t)
Tauira:
Mena ko te matotoru o te pakitara he 5mm → koki R ≈ 7.5mm–15mm
Tikanga Ine Papa
Ka taea te tirotiro i te koki R mā te:
✔ Ngā taputapu ine ine radius
✔ Ngā tauira porowhita ine
✔ Mīhini ine taunga kōtaha
Ngā Hipanga:
Whakatakotoria he ine, he tauira rānei ki te kokonga o te ngongo
Tauritehia te pewa taunga
Pānuihia te uara, tuhia rānei te manawanui taunga
Whakatauritea ki te paerewa, ki te whakaritenga tono rānei
I ētahi wā, ka whakamahia te matawai 3D, te CMM rānei i roto i ngā kaupapa nunui hei whakarite i te tika o ngā whakaahua.
He aha te hiranga o te koki R?
Ka pā te pūtoro kokonga ki:
✔ Kaha — ka whakaiti i te kukū o te ahotea
✔ Paninga — kia kapi ai ngā taha i te whakapūmau
✔ Whakarewa — whakapai ake i te kounga hanumi
✔ Ataahua — āhua maeneene ake
✔ Huinga — ka pā ki te urunga o te mokowā me te rahi o te hononga
Mō ngā ngongo tapawhā matotoru-paki, mō ngā tono hanganga rānei,ka taea e te koki R hē tehua akengā āputa, ngā raruraru whakarewa, ngā mōrearea ngenge huna rānei.
Ngā Mea hei Tirotiro ina Hoko Ana i te Rino me ngā Whakaritenga Koki R
Me aromatawai ngā kaihoko:
① Whakaū i te Whakatutukitanga Paerewa
Pātai atu ki te kaiwhakarato ko tēhea tukanga hanga me te paerewa e whaihia ana e rātou
(He rerekē ngā āhua kokonga o ngā EN10210, EN10219, GB, JIS, BS).
② Me whakarite kia tutuki i te Radius ngā hiahia o te tono
R nui → paninga maeneene, kaha ake, māmā ake
R iti → ngā taha koi ake, te piripono o te hononga
③ Tirohia te Matotoru o te Pakitara me te Taurite o te R
He rite te whānui o te kokonga ki te matotoru o te pakitara—ki te iti rawa te whānui mō ngā ngongo matotoru, he tohu tēnei i te hanganga hē.
④ Manatokohia te Ine Tuturu
Tono:
Ngā raraunga whakamātautau ine radius
Ngā whakaahua tapahi-mutunga
Pepa tirotiro ine
⑤ Kia Aro ki te Tukatuka-Mua
Ko te whakawaiwai, te wero, te miihini rānei i te mea wera me whai whānui kokonga e tika ana mō te rere o te paninga me te pumau o te hanganga.
Whakamutunga
Ehara te koki R i te mea whakapaipai noa iho.
Ka pā ki te kounga hanga, te mahi kawenga,te roa o te ratonga, me te tika o te tāutanga.
Mā te mārama ki te tautuhi a ngā paerewa rerekē i te pūtoro kokonga—me te mōhio hoki ki te ine me te aromatawai—ka āwhina i te whiriwhiri rauemi tika me te whakarite i ngā hua hangarau pono.
