Mīhini huri: ngā whakaritenga hangarau

Mata huaina mihini motuhake e whakamahia mō te horoi i te mata o ngā tuhinga o ngā papa faufaa. Nuinga o ngā wā, kei te whakamahia tenei momo o taputapu mo te maimoatanga o reni rakau. Heoi, mata huri mīhini mō te whakarewa - te reira ano hoki te momo tino noa o ngā waeine. E whakamahia ratou mo machining o maitai, te konumohe, parahi, me te rite. D.

He hītori iti

Mata mīhini huri whakaaro i roto i 1874 i roto i Amerika. I te tīmatanga, ka rite ki te taputapu mahi e whakamahia ana ki reira porowhita tapahia i mongamonga mārō o rerekē momo o toka auaha. No te mea i ratou ki te whakaputaia ketia pinepine, e kore te ngā horapa taua wae i te wa i riro. Heoi, kua i roto i te 1893, i muri i te tenenga o abrasives horihori, kua meinga mata huri mīhini rawa rongonui, me te rongonui.

He aha te whakamahi

Kei te whakamahia ngā taputapu o tenei momo mo:

• murua faaineineraa;

• tapahi me wāhanga;

• pū machining o papa o nga wahi;

• horoi niho wira;

• mutunga o te miro, me pera i runga i. d.

Ko te āhuatanga matua o enei mihini ko e he tika hoki ratou oti wāhanga ki te mata papatahi. Hoki i oti āhua mahi kore ratou e whakamahia.

parau tumu o te mahi

hāngai ana te mahi o tenei momo o te taputapu kei i runga i te parau tumu tino māmā. hua tahuri preform e hurihuri i te wira auaha tere tiketike. whakaratohia te kaupapa whakamutunga e te pūkaha hiko. I roto i tenei tukatuka kia whakamana rite te mata porohita me tona mutunga. I teie mahana, i runga i te hoko i reira tae atu mihini o tenei momo ki e rua porowhita he kaha rawa nui.

Mahi i roto i te nuinga o te wā, puea huri mīhini e whai ake:

• Ko te pūkaha tītaka te papu taputapu, akina hinu ki te takere o te pūnaha waipēhi.

• Aita i maoro a'e, patu he pouaka pana, e tika ana ki te tap timata.

• A, no te tahuri koe ki runga ki te hinu tap rere ki te wahi puoto supply me neke te kōkeke, me i te wa ano herea ia ki a ia te tepu.

• I te mutunga o to koutou tepu tahuri tahuri te piha whakakā i te kawenga mō te aronga o te hinu i roto i te tākai i te tahi atu puoto kai ranei.

• Kei te hoki whakamuri te hinu aronga o nāianei i te wa ano, ka tīmata te tepu ki te neke i muri ia ia.

Āhuatanga hoahoa

mihini huri o tenei momo e te nuinga o te āhuatanga e kaha tiketike no te mea ko nga tūemi tukatuka i roto i te nuinga o te wā i te taimaha nui. Mōrahi preform papatipu whakaaetia ko 600 kg, me te tiketike - 280 mm.

taputapu mīhini tīwae-momo eke e te i runga i te turanga, whakarewa i roto i te kotahi wahi ki te turanga. I roto i te waenganui o ona wahi kua reira he hikinga i runga i ngā taha e rua o nei i reira he kaiarahi. E ai ki nga nekehanga hariata whakamutunga. whakaritea ia huapae whakapae, whakaritea i raro i te headstock.

eke te workpiece i roto i taua mīhini te rānei tika i runga i te tepu te whakamahi i hononga autō motuhake ranei. I te tahi taime whakatika wahi, a tono pūrere aunoa.

Ka taea e mata Ripanga huri mīhini kia a tawhio tapawhā ranei. Tei runga i te tikanga i whiriwhiri o tuku tūemi: roa porohita ranei. I ētahi wā kei te whakamahia i tēnei momo o te taputapu mō te te machining rohe rawa nui. I roto i tenei take, he tikanga whāngai hake. Ko te mīhini mata tepu huri rawa ki te paninga PTFE motuhake. whakarato ana tēnei kaupapa maeneene me tona ātete ki te kakahu.

Ka taea te tūnga mīhini muka mata huri i roto i ngā huarahi rerekē. I runga i tenei kaupapa kua wehea te taputapu ki poutū me te whakapae. Ia o enei rōpū kua ona painga e rua me ngā huakore.

Ka rite ki tetahi atu mata tikanga e denoted mīhini huri tau rangatū. Tāutuhia e taua tapanga kore e taea e taputapu mahi. Ki te mahi i tenei, tirohia te mihini uruwhenua Mata huri.

Huri wāhanga mutunga

He maha ngā momo o taua wāhanga tukatuka:

• Multipass. I roto i tenei take, eke te workpiece i runga i te mata mahi, me te neke i te tere o e pā ana ki 45 m / s. oho te workpiece te i raro i te porohita e rave rahi taime, ka whangai i te muri e ki te hohonu māmālie tae noa tae noa apa whakarewa nekehia atu rakau e hiahiatia ana matotoru ranei.

• Single-haere. whakamahia ana tēnei tikanga i runga i ngā mīhini ki te tepu a tawhio. I roto i tenei take, whangai te taputapu e ki hohonu tonu i roto i te kotahi haere poutū.

• Double-taha. tukatuka wā kotahi taua taputapu i kotahi pito e rua o te preform.

huri taha

Kei te whakamahia i tēnei tikanga mō te machining o ngā wāhanga i hanga o ngā rauemi pakeke e kore rawa. huri piringa ko:

• Hohonu. I roto i tenei take, mo ia huringa tukatuka nekehia atu te kahu rawa nui o rauemi.

• Ki te infeed. Kei te whakamahia i tēnei tikanga mo te maimoatanga o te hunga workpieces tona roa ko nui atu te whanui.

• Ki te kai taratahi. Tenei hangarau ka taea huri paraoa kounga mōrahi noa workpieces rawa nui.

Porowhita huri mīhini

Ka taea te hangaia ēnei taputapu i roto i te puka o te mōria te rango ranei. ngā ratou o ngā momo o purapura o rauemi auaha o rigidity tiketike, hono ki tetahi ki tetahi ki uku, bakelite nape vulcanite ranei. Huri wira kia whai rahi rerekē, me te kōtaha. E tīpakohia ratou i runga i te hanga o te mīhini me te momo o te wahi tukatuka runga reira rānei.

taputapu kōwhiringa

Tino maha hono mīhini huri taputapu pērā i te wae meangiti. He mea tika ki te whakaiti i te pāmahana o te wahi mahi o te mīhini i roto i te kōrero tukatuka. hanga tenei taea reira ki tino whakawhānui ratou ora mahi.

i roto i te mihini o tenei momo taea te whakamahi hoki he kōwhiringa, rite te tūmau me te takai kaiwhiwhi, inverters tere, ngā wae purenga mo te coolant, a na i runga i. D.

āhuatanga hangarau

Mihini o tenei momo e taea rerekē i roto i te mana, mahi me te taumahinga. E faahoho'ahia Scheme mō te mata mihini huri i runga i tenei whārangi. Whakatakotoranga i roto i tenei momo o te taputapu e taea e rerekē. Next, kia kite a he aha ngā kōwhiringa e ki te whai i taua mihini i runga i te tauira o te tauira tino hira 3G71. Kei te anake te tikanga tenei kōwae mō te huri piringa o workpieces. Kei tōna hoahoa o anga, tīwae, me te kuia, he tēpu mahi, me te pūnaha waipēhi.

Ka taea te kitea i roto i te ripanga i raro, e kua te ngā mīhini huri.

Ahakoa te meka e te mata whakawhanakehia huri mīhini 3G71 i tonu i roto i te Soviet Union, Kei te whakamahia tonu te reira i roto i te whakangao me te whakaaro rawa pai, me te pono. I tona turanga e hangaia atu mātanga me mīhini utu 3G71M.
