Puas yog lub taub hau txias thiab txias extrusion yog tib yam, thiab qhov txawv ntawm ob yog dab tsi?
Lub taub hau txias thiab txias extrusion yog qhov pib deformation ua nyob rau hauv tib yam kev mob, tab sis lawv txoj kev khiav hauj lwm txawv. Cov blocks txias yog rau forging deformation ntawm cov khoom me me thiab feem ntau siv hauv kev lag luam fastener. Txias extrusion, ntawm qhov tod tes, belongs rau deformation ntawm workpieces loj thiab yog dav siv.
01 Dab tsi yog txias extrusion
Txias extrusion yog ib txoj hauv kev uas muab cov hlau dawb paug rau hauv qhov txias extrusion tuag kab noj hniav thiab siv lub siab rau qhov khoob los ntawm qhov chaw ruaj khov tuag ntawm lub xovxwm ntawm chav tsev kub, ua rau cov yas deformation ntawm cov hlau dawb paug thiab tsim cov khoom. Obviously, txias extrusion txheej txheem cia siab rau cov pwm los tswj cov ndlwg ntawm hlau thiab kev hloov ntawm ib tug loj npaum li cas ntawm cov hlau ntim rau hauv daim ntawv.
Yog tias qhov khoob yog extruded yam tsis muaj cua sov, nws yog hu ua txias extrusion. Txias extrusion yog ib qho ntawm cov txheej txheem ua tiav hauv cov hlau nti yas ua, vim nws yog ib qho ntawm cov txheej txheem rau machining qhov chaw uas tsis muaj los yog ob peb nti. Yog hais tias qhov khoob yog rhuab mus rau qhov kub ntawm qhov kub ntawm recrystallization rau extrusion, nws yog hu ua sov extrusion. Sov extrusion tseem muaj qhov zoo ntawm tsawg dua thiab tsis muaj chips.
Txias extrusion tshuab yog cov txheej txheem ntau lawm technology nrog high precision, efficiency, zoo, thiab tsawg noj, uas yog dav siv nyob rau hauv loj-scale zus tau tej cov me me thiab nruab nrab forgings. Piv nrog cov txheej txheem kub forging thiab sov forging, nws tuaj yeem txuag tau 30% txog 50% ntawm cov ntaub ntawv, txuag 40% mus rau 80% ntawm lub zog, thiab txhim kho qhov zoo ntawm forgings thiab qhov chaw ua haujlwm.
Tam sim no, txias extrusion tshuab tau dav siv nyob rau hauv industrial sectors xws li fasteners, machinery, instruments, electronics, light industry, aerospace, shipbuilding, thiab tub rog kev lag luam, thiab tau los ua ib tug indispensable thiab tseem ceeb ua txoj kev nyob rau hauv cov hlau yas ntim txoj kev technology. . Nrog rau kev nce qib ntawm thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov khoom siv thev naus laus zis hauv kev lag luam xws li tsheb, maus taus, thiab cov khoom siv hauv tsev, txias extrusion ntau lawm tshuab tau maj mam dhau los ua cov kev taw qhia ntawm precision zus tau tej cov me me thiab nruab nrab forgings.
Txias extrusion tseem tuaj yeem muab faib ua rau pem hauv ntej extrusion, thim rov qab extrusion, composite extrusion, radial extrusion, thiab lwm yam.
02 Lub Caij Nplooj Ntoos Zeeg yog dab tsi
Cov txheej txheem txias txias yog ib qho ntawm ob peb yam tshiab uas tsis yog txiav hlau siab ua cov txheej txheem. Nws yog ib txoj kev ua uas siv cov yas deformation ntawm hlau nyob rau hauv sab nraud quab yuam, thiab nrog kev pab los ntawm pwm, redistributes thiab hloov lub ntim ntawm hlau los tsim qhov yuav tsum tau qhov chaw los yog blanks. Cov txheej txheem txias txias yog qhov tsim nyog tshaj plaws rau kev tsim cov txheej txheem fasteners xws li bolts, screws, ceev, rivets, thiab pins. Cov khoom siv feem ntau siv rau kev siv tshuab txias taub hau yog lub tshuab txias taub hau tshwj xeeb. Yog tias qhov ntim ntau lawm tsis loj dhau, lub crank xovxwm lossis kev sib txhuam xovxwm kuj tuaj yeem siv los hloov.
Kev siv tshuab txias txias tau nce dav siv hauv kev tsim khoom, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov txheej txheem fasteners, vim nws cov khoom tsim tau zoo, cov khoom zoo, thiab kev txo qis hauv cov khoom siv, cov nqi tsim khoom, thiab kev ua haujlwm zoo. Ntawm lawv, feem ntau cov neeg sawv cev cov khoom tsim los ntawm ntau lub chaw nres tsheb txias taub hau tshuab yog bolts, screws, thiab ceev.
Puas yog lub taub hau txias thiab txias extrusion yog tib yam?
Txias pier thiab txias extrusion yog qhov pib deformation ua nyob rau hauv tib yam kev mob, tab sis lawv txoj kev khiav hauj lwm txawv. Cov blocks txias yog rau forging deformation ntawm cov khoom me me thiab feem ntau siv hauv kev lag luam fastener. Txias extrusion, ntawm qhov tod tes, belongs rau deformation ntawm workpieces loj thiab yog dav siv; Lub taub hau txias yog sib npaug rau ib ceg ntawm txias extrusion. Cias muab tso, nyob rau hauv tus txheej txheem ntawm kev ua bolts, lub hexagonal lub taub hau txoj kev belongs rau lub taub hau txias, thiab tus pas nrig txoj kab uas hla txo belongs rau txias extrusion (forward extrusion). Tsis txiav hexagonal flange bolts (ntau qhov chaw nres tsheb sib sau) muaj ob lub taub hau txias thiab txias extrusion. Ua ntej tsim cov txiv ntoo hexagonal, tsuas yog lub taub hau txias yog siv rau kev tsim, thaum cov txheej txheem tom ntej ntawm lub qhov extrusion belongs rau txias extrusion (rau pem hauv ntej thiab thim rov qab extrusion).
