He Taipitopito Taipitopito O Te Hangarau Miihini Porohita

Hei whakautu ki nga whakaritenga o runga ake nei, he tauira e whai ake nei. He miro carburizing (whakaahua i runga ake nei), 40 nga wahi mo ia puranga, rauemi 20Cr, engari mo nga miro o roto me waho S0.9 ~ C59. He uaua ake te mahi waro, a me tuhi he huahua o te tukanga mo te tukanga taratara (whakaahua).

Ko te hanganga o nga whakaritenga whakaritenga i roto i nga waahanga o te tokotoko e pa ana ki te kounga o te waahanga mahi, te hua o nga kaimahi me nga painga ohaoha.

Ka taea e tetahi waahanga te maha o nga tikanga tukatuka, engari ko tetahi anake te mea tika ake. I roto i te whakatakotoranga o te te mahi miihini whakaritenga, me tuhi nga mea e whai ake nei.

• 1.I roto i te tukanga tātaritanga o nga waahanga tuhi, he mea tika kia mohio ki nga whakaritenga hangarau o nga ahuatanga o te hanganga, te tika, te rauemi, te maimoatanga wera, me etahi atu, me te ako i te tuhi huinga hua, te tuhi huinga huinga me nga paearu whakaaetanga.
• 2.Ko te tikanga te huarahi tukatuka o nga wahanga carburizing: tapahi → whakatipu → whakarite → taratara → āhua-oti → carburizing → tango waro tukatuka (mo te wahi e kore e hiahia ki te whakapai ake i te pakeke) → tinei → miro, keri, mira ranei Groove → huri taratara → iti pāmahana hoholo → āhua-whakaoti → iti te pakeke o te pāmahana → whakaoti.
• 3.Kōwhiringa tohutoro taratara: Mena he mata kore-miihini, me whiriwhiri te mata kore-miihini hei tohutoro taratara. Mo nga toki maka e tika ana kia miihini ki runga i nga mata katoa, ka whakatikahia te mata iti kia rite ki te utu miihini. A ka whiriwhiri i te mata maeneene, kia te kuwaha. Tīpakohia he mata totoka me te pono hei tohutoro taratara, i te mea kaore e taea te whakamahi ano te tohutoro taratara.
• 4.He pai te kowhiringa tohu tohu: ki te whakatutuki i te maataapono o te tuuponotanga o te turanga, i te mea ka taea ki te kowhiri i te kaupapa hoahoa, i te huinga huinga ranei hei tohu tohu tuunga. I runga i te kaupapa o te tohu tohu. Whakamahia te tohutoro tuunga rite i te nuinga o nga mahi. I te mea e taea ana, ka rite te tohutoro tuunga ki te tohutoro ine. Ko te kowhiringa o te tino tika, te mata pumau me te pono he tohu pai.

Ko etahi tohu mo te mahi miihini o te rakau:

• 1.Ko nga rua pokapū e whakamahia ana hei tohutoro tuunga, e rite ana ki te maapono kua kiia ake nei mo te tupono tohutoro me te tohu tohu.
• 2.Ko te waahanga tuatahi ka whakamahi i te porowhita o waho hei tohutoro taratara, te mata mutunga o te motuka me te kohao pokapū o te drill, katahi ka tuuhia te porowhita o waho o te motuka taratara me nga rua pokapū hei tohutoro tuunga, a ka tukatukahia te kohao taper me te porowhita o waho o te motuka taratara hei tohutoro tuunga, koinei te kaupapa o te korero tahi. Ko te mahi miihini he tohu tuunga he tika ake i te kotahi. Nama 3 He tino tiketike nga whakaritenga tika o te koo Mohs. No reira, ka hiahiatia te ahua-V ki te whakatutuki i te whakaritenga whakaahuru ahuahanga me te porowhita o waho o te 2-ф30js5 hei tohutoro tuunga. I te wa e noho ana te koeko ki roto i te motuka, ka rawhi tetahi pito ki te maikuku, ka noho tetahi pito ki te anga o waenganui, ka whakamahia ano te porowhita o waho hei tohutoro pai.
• 3.I te wa e whakaoti ana me te whakaoti i te porowhita o waho, ka whakamahia he mono cone, ka whakamahia te poka waenganui o te koeko hei tohutoro tuunga mo te whakaoti i te mata porohita o waho o te rakau.

Mo nga whakaritenga mo te mono koekoe:

• 1.Cone plug he tino tika, me te whakarite ko te mata taper o te plug cone he tohu teitei o te concentricity me tona kohao matamata.
• 2.Kaua e whakakapihia te mono cone i muri i te whakaurunga ki te whakaiti i te hapa o te whakaurunga na te whakaurunga tonu.
• 3.Ko te diameter o waho o te diameter o waho o te mono cone me hanga tata ki te pito o te rakau hei whakahaere i te tango me te tango i te koo.
• 4.Ko te matua pou miihini ka warohia, ka whakapakeketia ki te 20Cr iti-carbon koranu maitai, a kaore e hiahiatia kia whakapakeketia te mea mahi (M30×1.5-6g maui, M30×1.5-6g, M12-6H, M6-6H), ka waiho te 2.5-3mm te tango waro paparanga i runga i te mata. .
• 5.I muri i te tineia o te miro, kaore e taea te tukatuka i runga i te miihini. Mena ka wirihia te miro i te tuatahi ka tineia, ka hee te miro. Na reira, karekau te miro e tuku kia whakapakeke, no reira me waiho te paparanga waro ki te diameter me te roa o te wahanga miro i roto i te taputapu mahi. Mo nga miro o roto, me waiho ano he paparanga decarburization 3 mm ki te orifice.
• 6.I roto i te tikanga ki te whakarite i te tika o te poka pokapū, te poka pokapū o te workpiece e kore hoki e whakaaetia kia whakapakeketia. Mo konei, ko te tapeke roa o te papaa he 6 mm.
• 7. Hei whakarite i te tika o te hurihanga o te porowhita o waho o te mahi, me whakarite te tukanga o te hurihanga o te poka o waenganui i muri i te maimoatanga wera, me te pai o te mata o te mata. I te wa e pa ana te porowhita o waho, ko te porowhita e pa ana ki te mea mahi na te noho tahi o nga rua o runga me te hapa porowhita o te kohao o runga.
• 8.I roto i te tikanga ki te whakakore i te ahotea huri, he tukanga hoholo pāmahana iti (te tunu) kua whakaritea i muri i te huri taratara.
• 9.Ki te whiwhi i te porowhita o waho tino tika, me wehewehe te huri ki te huri taratara, te tapahanga, me te huri pai. Ka whakaritea te huri miro pai ki runga i te miihini hurihuri tino tika.
