Lub taub hau txias thiab txias extrusion yog qhov pib deformation ua nyob rau hauv tib yam mob, tab sis lawv txawv hauv kev ua haujlwm. Txias pier yog forging deformation ntawm me me workpieces thiab feem ntau siv nyob rau hauv kev lag luam fastener. Txias extrusion belongs rau extrusion deformation ntawm workpieces loj thiab muaj ntau yam kev siv.
01
dab tsi yog txias extrusion
Txias extrusion yog muab cov hlau dawb paug rau hauv qhov txias extrusion tuag kab noj hniav, thiab nyob rau hauv chav tsev kub, siv lub siab mus rau qhov dawb paug los ntawm cov taag punch ntawm cov xovxwm kom cov hlau dawb paug tsim yas deformation thiab ua qhov chaw. Obviously, txias extrusion Xovxwm ua nyob rau hauv cov pwm los tswj cov hlau ntws, thiab cov ntaub ntawv los ntawm kev hloov ib tug loj npaum li cas ntawm hlau ntim.
Yog tias qhov khoob yog extruded yam tsis muaj cua sov, nws yog hu ua txias extrusion. Txias extrusion yog ib qho ntawm cov chip-dawb thiab nti-tsawg cov txheej txheem ua cov txheej txheem, yog li nws yog ib qho txheej txheem siab heev hauv cov hlau chip yas ua. Yog hais tias qhov khoob yog rhuab mus rau qhov kub hauv qab 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 ib qho kev siv technology siab heev nrog kev ua haujlwm siab, kev ua haujlwm siab, kev ua haujlwm siab thiab kev siv tsawg. Nws yog feem ntau siv nyob rau hauv loj-scale zus tau tej cov me me thiab medium-qhov loj qhov me forgings. Piv nrog cov txheej txheem kub forging thiab sov forging, nws tuaj yeem txuag tau 30 feem pua rau 50 feem pua ntawm cov ntaub ntawv thiab 40 feem pua rau 80 feem pua ntawm lub zog, thiab tuaj yeem txhim kho qhov zoo ntawm forgings thiab txhim kho qhov chaw ua haujlwm.
Tam sim no, txias extrusion tshuab tau dav siv nyob rau hauv fasteners, machinery, instruments, hluav taws xob khoom, lub teeb kev lag luam, aerospace, shipbuilding, tub rog thiab lwm yam sectors, thiab tau los ua ib tug indispensable thiab tseem ceeb ua txoj kev nyob rau hauv cov hlau yas ntim txoj kev technology. ib. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov khoom tsim nyog hauv kev lag luam xws li tsheb, maus taus, thiab cov khoom siv hauv tsev, txias extrusion tshuab tau maj mam dhau los ua cov kev taw qhia ntawm kev ua kom zoo ntawm cov khoom me me thiab nruab nrab forgings.
Txias extrusion kuj muab faib ua rau pem hauv ntej extrusion, thim rov qab extrusion, composite extrusion, radial extrusion thiab hais txog.

Dab tsi yog lub taub hau txias
Cov txheej txheem txias taub hau yog ib qho ntawm ob peb txheej txheem tshiab rau kev ua cov hlau tsis-txiav. Nws yog ib txoj kev ua haujlwm uas siv cov yas deformation ntawm cov hlau nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, thiab nrog kev pab los ntawm pwm, redistributes thiab hloov cov hlau ntim los tsim qhov yuav tsum tau cov seem 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 cuab yeej siv feem ntau siv hauv cov txheej txheem txias taub hau yog lub tshuab txias taub hau tshwj xeeb. Yog tias qhov ntim ntau lawm tsis loj heev, nws tuaj yeem hloov tau los ntawm crank xovxwm lossis kev sib txhuam xovxwm.
Cov txheej txheem txias lub taub hau yog ntau thiab siv dav 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 cov khoom siv txo qis, txo cov nqi tsim khoom, thiab txhim kho kev ua haujlwm. Cov khoom sawv cev tshaj plaws uas ua los ntawm ntau lub chaw nres tsheb txias taub hau yog bolts, screws thiab ceev.
03
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 txawv hauv kev ua haujlwm. Txias pier yog forging deformation ntawm me me workpieces thiab feem ntau siv nyob rau hauv kev lag luam fastener. Txias extrusion belongs rau extrusion deformation ntawm workpieces loj, thiab muaj ntau yam kev siv; txias taub hau yog sib npaug rau ib ceg ntawm txias extrusion. Txoj kab uas hla belongs rau txias extrusion (zoo extrusion). Non-cutting hexagonal flange bolts (multi-station forming) muaj ob qho tib si txias taub hau thiab txias extrusion. Lub hauv ntej shaping ntawm hexagonal txiv ntseej tsuas yog lub taub hau txias, thiab cov txheej txheem tom ntej ntawm extrusion yog txias extrusion (zoo thiab thim rov qab extrusion).
