Te whakakikorua i te taiaho: he tikanga whakahou matomato e werohia ana te "pūeru pakari" ki roto i ngā miihini waro

I raro i te hohonutanga o ngā maina waro, ka oho ngā pou tautoko waipēhi i roto i ngā pūnaha maina kua oti te miihini i raro i te pēhanga 10,000-tana, ka huri ngā awa kawe waru ki te hononga waro, i te mea ka uaua ngā rango waipēhi ki te mahi i roto i ngā taiao makuku me te waikura. Ko ēnei wāhanga nui te "anga maitai" o ngā mahi maina waro, e mau tonu ana te kakahu, te waikura, me te pānga mō ngā wā roa. Ko ngā tikanga tiaki tuku iho pēnei i te whakarewanga paparua, te whakakikorua chromium, te whakakapinga katoa rānei, ehara i te mea he utu nui me te roa, engari kāore hoki e tutuki i ngā hiahia o te maina waro hou mō ngā mahi whai hua, iti-waro, me te whai hua. Ko te putanga mai o te hangarau whakakikorua laser kei te arahi inaianei i tētahi "hurihanga whakaora maitai" marino mō te umanga mīhini waro.

I. Te whakakikoruatanga taiaho: "pokanga tika" o te hanga anō i ngā mīhini waro

Ehara te whakakikoruatanga reera i te "kiriata" mata noa, engari he hangarau hou e hanga ana i te puna rewa iti ki runga i te mata o te wāhanga me te hihi reera kaha teitei, ā, i te wā kotahi ka rehuhia te paura koranu motuhake hei whakatutuki i te hononga whakarewa i waenga i te paparanga whakakikoruatanga me te turanga. Ko tōna uara matua ko:

Te whakatikatika tika i te ūnga: Ka taea te whakanoho tika i te hihi taiaho ki ngā awaawa me ngā poka waikura, kia kore ai e pakaru te papa hauora, he mea tino pai mō te whakatika i ngā hapa ā-rohe pērā i ngā karawarawa i runga i ngā pou waipēhi me ngā karawarawa i te pakitara o roto o ngā rango.

He hononga pakari, he hononga pakari hoki te whakarewa: Ka hangaia e te paparanga whakakikorua me te matihiko te hanumitanga horapa ngota, ko te kaha herenga tae atu ki te 400MPa, ka whakakorea rawatia te tūponotanga o te tihorenga whakakikorua chromium.

Mahi whakarite: Mā te whiriwhiri i te koranu ātete-kakahu e ahu mai ana i te cobalt (pērā i te Stellite 6), te koranu ātete-waikura e ahu mai ana i te nickel, te mea whakahiato rānei kua whakapakarihia ki te tungsten carbide, ka taea te whakapai ake i te kaha o ngā wāhanga ki te ora i roto i ngā āhuatanga mahi uaua pērā i te pānga o te gangue waro me te waikura kohu wai waikawa.

II. Te whakamahinga whai hua: Mai i te "wāwāhi i te taha" ki te "mahi nui rawa atu"

1. Tautoko waipēhi "huringa whakaroa ora"

I muri i te tihorea o te paparanga whakakikorua chromium i runga i te mata o te pou waipēhi, ka ngāwari te waikura o te pou, ka pakaru hoki i raro i te pēhanga teitei. Ka taea e te hangarau whakakikorua laser te:

I muri i te tango i te paninga tawhito, ka whakatakotoria tika ki te mata o te papa te paparanga koranu konupora matotoru 0.8-1.5mm;

Ka whakanuia te pakeke ki te HRC 55-60 (ko te paparanga whakakikorua chromium taketake he HRC 40-45 anake), ā, ka piki ake te ātete kakahu neke atu i te 3 ngā wā;

Kua tino whakarei ake te ātete ki te waikura. Ka tae te roa o te ora o te pou whakatika maina i roto i te wai maina waikawa ki te 18 marama, he nui atu i te mea hou taketake (6-8 marama).

2. Kua "whakahoutia" te awaawa o waenganui o te mīhini waru

Ka eke te pakaru ā-tau o te pereti o raro o te poka waenga ki te 15mm, ā, neke atu i te 20,000 yuan te utu mō te whakakapinga tuku iho mō ia waeine. Ka whakamahia e te otinga whakakikorua laser he rauemi rino whakakaha-pūmua tungsten carbide ki ngā wāhi pakaru o ngā pakitara poka waenga. Mā te whakatutuki i te pakeke o te mata e neke atu ana i te HRC 62, ka whakanui ake tēnei auaha i te ātete pakaru mā te 5-8 ngā wā. Ko ngā tono mara i roto i ngā wāhi keri e whakaatu ana ka roa ake te roa o te mahi a te poka waenga kua whakahokia mai i te 6 marama ki te 24 marama, ā, ka heke iho ngā utu tiaki mō ia tana waro mā te 40%.

3. "Te hanga anō" o te pakitara o roto o te rango waipēhi

Hei whakatika i te rahunga hiri i puta mai i ngā karawarawa o te pakitara rango: Ka whakamahia e te pūnaha te whāngai paura coaxial me te pūwero laser motuhake mō ngā kōhao o roto, ka taea ai te whakarewa tika i roto i ngā wāhi kuiti. Ko te taratara o te mata i muri i te whakatikatika (Ra ≤ 0.8μm) e hipa ana i ngā paerewa miihini wāhanga hou. Ko ngā whakamātautau mara i tētahi wheketere mīhini waro e whakaatu ana ka tutuki i ngā rango kua whakatikatikaina te 100% o te tutuki i te mahi hiri, engari ko te utu he 30% noa iho o te hanga rango hou.

III. Huringa Toru: Ōhanga, Whai Hua me te Huringa Kakariki

IV. Mai i te whakatikatika ki te whakapai ake: te heke mai o te hanga anō atamai o ngā miihini waro

Mā te whakaurunga o ngā hangarau atamai, kei te eke te whakakikorua laser ki ngā taumata hou i roto i ngā tono mīhini waro: 1) Ka taea e ngā teihana mahi karetao aunoa te whakatika i ngā wāhanga pēnei i ngā pou me ngā rango, ka whakanui ake i te pai o te mahi mā te 50%; 2) Ka aroturukihia e te tiaki matapae mahanga mamati te pakaru o ngā taputapu mā roto i ngā pūoko hei mahi wawe i ngā whakatika whakakikorua i mua i te puta o ngā hapa; 3) Ka whakawhanakehia e ngā rauemi mahi rōnaki ngā paparanga whakakikorua hiato me ngā mata o waho tino mārō hei ātete i te pakaru me ngā paparanga o roto kaha e ātete ana ki ngā kapiti, e aro pai ana ki ngā āhuatanga mahi e hono ana ki te pakaru me te pānga.
