Koj puas feem ntau ntsib cov ntsiab lus xws li "forging," "stamping," thiab "casting"? Lawv txhua tus zoo li muaj feem xyuam rau "kev tsim hlau," tab sis qhov txawv ntawm lawv yog dab tsi? Koj puas muaj kev ntxhov siab me ntsis? Tsis txhob txhawj! Niaj hnub no, peb yuav pab koj nkag siab txog peb cov txheej txheem no kom meej, tso cai rau koj yooj yim nkag siab txog kev tsim khoom lag luam tom qab lawv!
01
Qhov sib txawv ntawm Forging thiab Casting
(1) Kev xav txawv
Casting: Qhov no suav nrog kev nchuav cov hlau ua kua rau hauv cov pwm ua ntej -, tso cai rau nws kom txias thiab khov kho kom tau txais cov casting nrog ib qho tshwj xeeb thiab cov khoom. Tag nrho cov txheej txheem tuaj yeem raug suav hais tias yog: khoom → kua → khoom. Zoo ib yam li melting wax rau hauv cov kua thiab ncuav nws mus rau hauv pwm, cia nws txias thiab tsim cov duab uas xav tau.
Forging: Forging suav nrog kev siv lub zog sab nraud (kev cuam tshuam lossis siab) rau cov hlau hauv lub xeev ruaj khov kom ua rau cov yas deformation, yog li tau txais ib qho forging nrog cov duab tshwj xeeb, qhov loj me, thiab cov khoom. Nws tuaj yeem raug suav hais tias yog: khoom → khoom. Zoo ib yam li kneading mov paj, siv sab nraud quab yuam los hloov cov duab ntawm cov khoom hauv pwm.
· Casting tsom rau kev tswj lub melting thiab pouring txheej txheem ntawm hlau.
Forging yog ib qho khoom siv- lub xeev cov txheej txheem yas, uas tuaj yeem muab faib ua kub forging thiab txias forging, suav nrog cov txheej txheem tshwj xeeb xws li extrusion, kos duab, chim siab, thiab xuas nrig ntaus.
(2) Kev tsim cov txheej txheem thiab microstructure
Casting yog ib qho - lub sijhawm tsim cov txheej txheem, haum rau cov khoom uas muaj cov duab nyuaj lossis cov kab noj hniav hauv, tab sis yuav ua rau muaj qhov tsis xws luag xws li porosity thiab shrinkage vim txias shrinkage.
Forging yog ib qho kev sib sau ua ntu zus, feem ntau xav tau ntau yam deformations, uas tuaj yeem ua kom zoo hlau nplej thiab ua kom cov microstructure, yog li txhim kho lub zog thiab tawv ntawm qhov chaw.

Qhov sib txawv ntawm Free Forging thiab Tuag Forging
Dawb forging yuav muab tso rau ib tug rhuab billet ntawm sab sauv thiab qis forging blocks thiab deforming nws los ntawm kev cuam tshuam los yog siab kom maj mam tau cov yam xav tau. Nws yog qhov tsim nyog rau kev tsim cov duab yooj yim, cov khoom me me, lossis loj loj forgings.
* Kev Taw Qhia Free Forging: Kev siv zog ua haujlwm siab thiab ua haujlwm qis, feem ntau yog siv los kho lossis me me.
* Tshuab Free Forging: Txoj kev tseem ceeb ntawm kev tsim khoom niaj hnub, tshwj xeeb tshaj yog tseem ceeb hauv kev tsim cov tshuab hnyav. Tuag forging yuav muab tso rau ib tug rhuab billet rau hauv pwm kab noj hniav tsau rau forging khoom los tsim cov khoom kawg.
Cov cuab yeej siv feem ntau suav nrog chav - huab cua rauj (hom tonnage 0.5 ~ 30t) thiab kub tuag forging presses (hom tonnage 25000 ~ 63000KN).
Cov qauv tuag tuaj yeem yog ib qho -kab noj hniav lossis ntau- kab noj hniav. Lawv feem ntau ua ke nrog kev npaj billet thiab cov txheej txheem forging zaum kawg, nrog rau qhov kawg flash tshem tawm kom tau txais lub forging.

Qhov sib txawv ntawm casting, forging, stamping, thiab tuag casting
[Duab]
Tsis tas li ntawd, cov txheej txheem plaub no muaj cov ntsiab lus meej thiab kev faib ua haujlwm hauv kev siv tswv yim: Casting excels ntawm kev daws cov teeb meem ntawm complex configurations, tshwj xeeb tshaj yog tsim nyog rau tsim qhov chaw nrog complex sab hauv kab noj hniav, nkhaus nto, los yog irregular structures. Cov khoom no feem ntau yog qhov loj me thiab tsis siv ncaj qha los ua lub ntsiab thauj khoom -cov qauv kabmob.
Tus nqi tseem ceeb ntawm forging yog nyob rau hauv kev txhim kho cov khoom siv. Los ntawm cov yas deformation, nws refines nplej thiab densifies lub microstructure, ho txhim kho lub zog, toughness, thiab qaug zog lub neej ntawm qhov chaw. Yog li ntawd, nws yog cov txheej txheem nyiam rau siab - load structural Cheebtsam xws li bearings, gears, thiab txuas rods. Stamping yog txheej txheem sawv cev rau kev tsim cov ntawv nyias nyias. Nrog nws cov kev ua haujlwm siab heev thiab zoo sib xws ntawm qhov sib xws, nws tshwj xeeb hauv qhov loj - nplai tsim ntawm ntau yam yooj yim nyias- cov plhaub plhaub thiab cov khoom siv.
Tuag casting, ntawm qhov tod tes, tuaj yeem pom tias yog kev sib xyaw ua ke ntawm precision thiab efficiency. Thaum khaws cov txheej txheem tsim cov peev txheej ntawm casting, nws qhia siab - siab, siab - nrawm filling, ua kom cov khoom nyias nyias - cov phab ntsa nrog cov npoo du thiab qhov ntev ntawm ib qho dhau los. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov khoom loj ntawm precision qhov chaw ua los ntawm cov hlau tsis yog -ferrous xws li aluminium alloys thiab zinc alloys.
