Qhov sib txawv ntawm Die Castings thiab Tuag Forgings:
1. Qhov tseem ceeb ntawm qhov txawv ntawm Die Castings thiab Tuag Forgings (Liquid Forgings):
⑴ Qee lub koom haum nruab nrab hauv Suav teb, suav nrog cov khoom lag luam thiab ua tiav cov khoom lag luam, ua tiav cov xaj xaj thiab tom qab ntawd nrhiav cov tuam txhab tsim khoom hauv tsev los tsim lawv. Vim tias cov txheej txheem tsim khoom rau ob hom kev khoob no txawv, lawv cov nqi lag luam tam sim no kuj txawv; tus nqi tom kawg yog feem ntau siab dua tus qub. Yog tias ob hom kev khoob no tsis tuaj yeem paub qhov txawv, hais txog tus nqi qis ntawm kev tuag castings thaum txais kev lag luam yuav ua rau kev lag luam yuam kev, cuam tshuam cov txiaj ntsig lossis txawm tias poob.
⑵ Kev tshaj lij casting thiab forging manufacturers. Lawv tuaj yeem lees txais kev lag luam xav tias tom kawg yog kev tuag casting thiab tuaj yeem tsim tau siv cov txheej txheem tuag casting. Tom qab qhov tuag casting pwm raug qhib, cov blanks uas tsim los ntawm cov txheej txheem tuag casting feem ntau muaj cov kab noj hniav, qhov porosity, los yog defects, uas ua rau tsis tsim nyog blanks thiab thaum kawg tsis tsim nyog poob.
2. Kev sib raug zoo ntawm Die Casting & Forging, Liquid Forging, thiab Nruam Casting & Forging txheej txheem:
Lub ntsiab tseem ceeb ntawm kev nruam casting & forging yog ua kom tiav casting thiab forging nyob rau hauv tib txheej pwm ntawm ib lub tshuab. Nruam casting & forging tsis yog txheej txheem tshiab; nws cov ntsiab cai muaj keeb kwm ntev. Qhov feem ntau raug thiab yooj yim tshaj nruam nruam casting & forging txheej txheem yog cov paub ua kua forging txheej txheem. Tuag casting & forging, figuratively hais lus, yog ib tug txheej txheem uas siv heev automated tshwj xeeb cov cuab yeej los tsim kua forgings nrog cov qauv complex raws li zoo tib yam tuag castings. Vim li no, tuag castings thiab zoo tib yam tuag castings tsis yooj yim distinguishable nyob rau hauv tsos. Cov txheej txheem uas zoo sib xws rau cov blanks uas tsim los ntawm nruam casting & forging yog cov txheej txheem "cast-ces-forge" txheej txheem. Kev cam khwb cia-ces- txheej txheem forge yog ntau heev: cov khoom siv dawb paug yuav tsum muaj ob pawg pwm, ib qho rau kev tuav cov hlau zoo tib yam pwm casting, thiab lwm yam rau precision forging siv kev sib txhuam los yog hydraulic xovxwm.
3. Kev Taw Qhia Txog Kev Tuag Casting thiab Forging Txheej Txheem:
Kev tuag casting thiab forging yog txheej txheem ua tiav ntawm lub tshuab tshwj xeeb tuag casting thiab forging tshuab. Nws cov txheej txheem tseem ceeb suav nrog cov hlau molten raug cam khwb cia thiab ntim rau hauv pwm kab noj hniav ntawm qhov qis lossis siab ceev. Cov pwm muaj cov kab noj hniav uas txav tau, thiab lub siab yog siv raws li cov hlau molten txias, forging qhov khoob. Cov txheej txheem no tshem tawm cov kab noj hniav shrinkage thiab porosity defects nyob rau hauv qhov khoob thiab ua tiav ib qho forged, fragmented grain qauv. Lub zuag qhia tag nrho cov cuab yeej cuab tam ntawm qhov khoob yog qhov zoo tuaj. Tsis tas li ntawd, cov blanks uas tsim los ntawm cov txheej txheem no ua tiav qhov chaw tiav ntawm qib 7 (Ra1.6), zoo ib yam li cov chaw tsim los ntawm kev ua kom txias txias lossis tshuab ua haujlwm, ua kom pom cov xim hlau. Yog li ntawd, peb hu ua tuag casting thiab forging "txheej txheem txheej txheem," ib qho kev nce qib ntxiv dhau "tsis muaj-txiav, qis- cov txheej txheem sib sau." Lwm qhov kom zoo dua ntawm kev tuag casting thiab forging yog tias, ntxiv rau kev tsim cov khoom siv tsoos, nws tseem tuaj yeem siv wrought alloys thiab forging alloys los tsim cov khoom nrog cov qauv nyuaj heev. Cov qib alloy no suav nrog: tawv aluminium alloys, super- hard aluminium alloys, thiab forged aluminium alloys, xws li LY11, LY12, 6061, 6063, LYC, LD, thiab lwm yam. Lub zog tensile ntawm cov ntaub ntawv no yog ze li ntawm ob npaug ntawm cov hlau cam khwb cia zoo tib yam, uas yog qhov tseem ceeb dua rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntau dua li cov khoom siv hluav taws xob. tsis kam.
4. Cov txheej txheem kom paub qhov txawv ntawm ob hom kev khoob no:
Los ntawm cov tsos ib leeg, nws yog ib qho nyuaj rau kev paub qhov txawv ntawm qhov khoob uas tsim los ntawm ob txheej txheem no. Yog tias peb pom ib feem tiav lawm, nws tseem nyuaj rau qhov txawv. Yog li ntawd, peb tsuas tuaj yeem txheeb xyuas thiab txiav txim los ntawm qhov kev xav tsis sib xws: Ua ntej, tuag- ntu ntu feem ntau yog "cov qauv tsim," thaum tuag- nrum forgings yog "cov haujlwm ua haujlwm." "Structural parts" thiab "functional parts" yog cov lus txheeb ze. Cov yav tas feem ntau yog hais txog cov khoom uas yuav tsum tau tiv thaiv kev cuam tshuam, kub siab, siab, lub zog (lub zog), thiab yuav tsum tau kho deg (xws li anodizing) thiab kev kho cua sov (kev daws teeb meem). Cov khoom lag luam muaj xws li cov cav cav, log hubs, pistons, txuas rods, nres khau, thiab pneumatic lossis hydraulic valve lub cev (xws li peb hom - txoj hauj lwm tsib- txoj kev li qub). Cov qub suav nrog cov khoom xws li lub tsheb qhov rooj, cov cuab yeej ntsuas, thiab lub cav npog. Qhov thib ob, nws tuaj yeem txiav txim siab los ntawm cov khoom muaj pes tsawg leeg. Tuag castings feem ntau yog ua los ntawm cam khwb cia hlau; Lwm cov qib alloy feem ntau yog tsim los ntawm kev tuag casting thiab forging txheej txheem. Thib peb, nws tuaj yeem txiav txim siab los ntawm kev kho deg qhov yuav tsum tau ua ntawm qhov khoob. Piv txwv li, txhuas tuag castings muaj silicon, thiab cov blanks uas ua los ntawm cov txheej txheem tuag casting muaj micropores ntawm lawv sab nrauv. Tom qab anodizing, cov khoom no yuav muaj "dub me ntsis" ntawm qhov chaw. Yog li ntawd, yog tias qhov khoob yuav tsum tau anodizing, nws yuav tsis raug tsim los siv cov txheej txheem tuag casting zoo tib yam. Plaub, nws tuaj yeem txiav txim siab los ntawm cov qauv metallographic. Tuag castings thiab tuag casting forgings yog yooj yim distinguishable nyob rau hauv metallography. Lub qub muaj ib tug dendritic li - nrum qauv, thaum lub tom kawg muaj ib tug uniform, fragmented nplej raws li - nrum qauv.
5. Tshem tawm qee qhov kev xav tsis zoo:
(1) Peb tsis tuaj yeem ntseeg tias lub tshuab nqus tsev infiltration tom qab tuag casting tuaj yeem daws cov kab mob shrinkage thiab porosity defects hauv tuag castings, peb tsis tuaj yeem ntseeg tias lub tshuab nqus tsev tuag casting tuaj yeem siv los tsim cov khoom ua haujlwm uas yuav tsum tau ua haujlwm nruam thiab forging. Thaum kev lag luam thev naus laus zis nce qib, peb yuav tsum tau txais tus cwj pwm kev tshawb fawb uas ua kom nrawm nrog lub sijhawm hauv peb lub tswv yim thiab kev xav.
(2) Ob lub tshuab nqus tsev tuag castings thiab zoo tib yam tuag castings raug kev txom nyem los ntawm shrinkage kab noj hniav thiab porosity tsis xws luag. Lub tshuab nqus tsev tuag casting tsuas yog ua lub luag haujlwm me me hauv kev pabcuam venting piv rau cov tuag casting zoo tib yam; Nws yog kiag li tsis muaj txiaj ntsig tiv thaiv qhov shrinkage kab noj hniav thiab porosity tshwm sim los ntawm qhov shrinkage ntawm cov hlau molten thaum lub sij hawm hloov pauv (qhov twg sab hauv yog lub tshuab nqus tsev, tsis muaj roj). Thib peb, ib qho yuam kev ua los ntawm cov kws tshaj lij yog tias txawm hais tias lawv paub qhov khoob tsis tuaj yeem tsim los ntawm kev tuag casting zoo tib yam, lawv xaiv cov txheej txheem hu ua "rov qab punch indirect thiab ib nrab extrusion." Lawv yuam kev ntseeg tias cov txheej txheem no ua tiav tib yam li cov kua forging, uas yog qhov tsis ncaj ncees lawm. Lub ntsiab ntawm "rov qab punch extrusion" tseem yog txheej txheem tuag casting! Tsuas yog "forging nrog rau pem hauv ntej punch npog tag nrho qhov projected cheeb tsam" yog qhov tseeb ua kua forging txheej txheem.
6. Xaus:
Qhov sib txawv ntawm qhov zoo tib yam tuag castings thiab tuag- nrum forgings tseem yog ib txoj hauj lwm tseem ceeb heev. Txawm hais tias cov txheej txheem tsis yooj yim rau tus tswv, feem ntau ntawm nws cuam tshuam txog kev xav thiab kev txawj ntse.
