Stamping txheej txheem ntawm plaub txheej txheem loj hauv kev tsim tsheb
Lub tsheb yog hu ua "lub tshuab hloov lub ntiaj teb". Vim tias kev lag luam tsheb muaj kev sib raug zoo ntawm kev lag luam, nws tau suav tias yog lub cim tseem ceeb ntawm lub teb chaws txoj kev loj hlob theem. Muaj plaub txheej txheem loj hauv tsheb, thiab cov txheej txheem stamping yog qhov tseem ceeb tshaj plaws ntawm plaub txheej txheem loj.
1. Lub tswv yim ntawm stamping
Stamping yog ib txoj kev tsim uas tso siab rau cov xovxwm thiab tuag los siv rau sab nraud rau cov phaj, strips, cov kav dej thiab cov profiles kom ua rau cov yas deformation los yog sib cais, yog li tau txais cov khoom ua haujlwm (stamping qhov chaw) ntawm cov duab thiab qhov loj me. Stamping thiab forging yog cov txheej txheem yas (lossis kev ua haujlwm siab), suav nrog hu ua forging. Cov blanks rau stamping feem ntau yog kub-kuav los tiag thiab txias-kuav los tiag steel daim hlau thiab steel strips. Ntawm cov khoom siv hlau hauv ntiaj teb, 60-70% yog daim hlau, feem ntau yog stamped rau hauv cov khoom tiav.
Lub cev, chassis, roj tank, radiator fins ntawm lub tsheb, lub nruas ntawm boilers, lub plhaub ntawm cov thawv, cov hlau tub ntxhais silicon steel nplooj ntawv ntawm lub cev muaj zog thiab cov khoom siv hluav taws xob, thiab lwm yam yog tag nrho cov stamped. Kuj tseem muaj ntau qhov chaw stamping hauv cov khoom xws li cov twj paj nruag, cov khoom siv hauv tsev, tsheb kauj vab, cov tshuab ua haujlwm, thiab cov khoom siv niaj hnub.
2. Cov yam ntxwv ntawm cov txheej txheem stamping
A. Stamping yog ib txoj kev ua haujlwm nrog kev ua haujlwm siab thiab siv cov khoom siv tsawg. Cov txheej txheem stamping yog tsim rau zus tau tej cov loj batch ntawm qhov chaw thiab cov khoom, uas yog ib qho yooj yim kom paub mechanization thiab automation, thiab muaj ntau lawm efficiency. Nyob rau tib lub sijhawm, stamping ntau lawm tuaj yeem siv tsis tau tsuas yog kom ua tiav cov khoom pov tseg tsawg dua thiab tsis muaj pov tseg, tab sis kuj siv tag nrho cov khoom seem hauv qee kis.
B. Cov txheej txheem ua haujlwm yooj yim thiab tsis tas yuav tsum muaj tus neeg teb xov tooj kom muaj kev txawj ntse.
C. Cov khoom stamped feem ntau tsis tas yuav rov ua dua thiab muaj qhov raug siab.
D. Stamping qhov chaw muaj kev sib hloov zoo. Cov txheej txheem stamping muaj kev ruaj ntseg zoo, thiab tib batch ntawm stamping qhov chaw tuaj yeem siv sib hloov tsis cuam tshuam rau kev sib dhos thiab kev ua haujlwm ntawm cov khoom.
E. Txij li thaum stamping qhov chaw siv cov ntaub ntawv, lawv qhov zoo ntawm qhov chaw yog qhov zoo, uas muab cov kev mob yooj yim rau cov txheej txheem tom ntej ntawm kev kho deg (xws li electroplating thiab pleev xim).
F. Stamping tuaj yeem tsim cov khoom muaj zog, siab rigidity thiab lub teeb yuag.
G. Stamping qhov chaw loj-tsim nrog pwm yog pheej yig.
H. Stamping tuaj yeem tsim cov khoom nrog cov duab nyuaj uas nyuaj rau tsim nrog lwm txoj kev ua hlau.
3. Taw qhia txog txheej txheem stamping
Mechanical steering system siv tus neeg tsav tsheb lub cev lub zog ua lub hauv paus ntawm lub zog tsav, thiab tag nrho cov txheej txheem kev sib kis ntawm cov khoom siv tshuab yog cov tshuab. Lub tshuab hluav taws xob tswj lub tshuab muaj peb qhov tseem ceeb: kev tswj lub kauj, lub kauj iav thiab lub kauj tsav tsheb.
A. Kev sib cais
Cov ntawv hlau yog sib cais raws li ib qho contour kab nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam kom tau cov khoom tiav thiab cov khoom tiav ib nrab nrog cov duab, qhov loj me thiab txiav qhov zoo. Kev sib cais: qhov kev ntxhov siab nyob rau hauv cov khoom deformed tshaj lub zog txwv σb.
ib. Ncua tseg
Siv lub punch rau punch raws qhov nkhaus kaw, thiab qhov punched yog ib feem. Siv los tsim qhov chaw tiaj tus ntawm ntau yam duab.
b. xuas nrig ntaus
Siv cov xuas nrig ntaus rau ntawm qhov nkhaus kaw, thiab qhov punched yog pov tseg. Muaj ntau hom ntawv xws li xuas nrig ntaus zoo, sab xuas nrig ntaus, thiab dai xuas nrig ntaus.
c. Txiav
Txiav cov npoo ntawm qhov tsim kom zoo zoo los yog txiav rau hauv ib qho zoo.
d. Kev sib cais
Siv cov xuas nrig ntaus rau ntawm ib qho nkhaus uas tsis tau kaw los tsim kev sib cais.
Thaum sab laug thiab sab xis yog tsim ua ke, txoj kev sib cais yog siv ntau zaus.
B. txheej txheem tsim
Cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Cov txheej txheem tsim: tawm lub zog σS < cov khoom siv hauv kev ntxhov siab < lub zog txwv σb.
ib. Kev kos duab
Ua daim ntawv dawb paug rau hauv ntau qhov qhib hollow.
b. Flanging
Tsim cov npoo ntawm daim ntawv lossis cov khoom tiav ib nrab ntawm ib qho kev nkhaus nrog qee qhov curvature los ua ib txoj kab ntsug.
c. Kev tsim
Ib txoj kev tsim siv los txhim kho qhov tseeb qhov tseeb ntawm qhov tsim los yog kom tau txais lub vojvoog me me.
d. Flanging
Ua cov npoo ntsug ntawm cov ntawv ua ntej punched los yog cov khoom ua tiav los yog cov ntawv tsis muaj punched.
e. Khoov
Khoov daim ntawv rau hauv ntau yam duab raws txoj kab ncaj nraim, thiab cov khoom uas muaj cov duab tsis tshua muaj heev tuaj yeem ua tiav.
