Stamping txheej txheem Classification

Stamping feem ntau yog cais raws li txheej txheem thiab tuaj yeem muab faib ua ob pawg: txheej txheem sib cais thiab txheej txheem tsim. Txoj kev sib cais tseem hu ua blanking. Nws lub hom phiaj yog cais cov stamping qhov chaw los ntawm daim ntawv raws li ib tug tej yam contour kab thaum xyuas kom meej qhov zoo yuav tsum tau ntawm lub cais seem. Lub hom phiaj ntawm kev tsim cov txheej txheem yog kom plastically deform cov ntaub ntawv yam tsis tau tawg qhov khoob thiab ua ib qho workpiece ntawm qhov xav tau cov duab thiab qhov loj me. Hauv kev tsim khoom tiag tiag, ntau cov txheej txheem feem ntau siv rau ib qho chaw ua haujlwm. Blanking, dabtsi yog khoov, shearing, kos duab, bulging, spinning thiab kho yog lub ntsiab stamping txheej txheem.
Kev sib cais
(Blanking)
Nws yog ib qho yooj yim stamping txheej txheem uas siv pwm los cais cov ntaub ntawv. Nws tuaj yeem ua ncaj qha rau hauv qhov chaw tiaj tus lossis npaj qhov khoob rau lwm cov txheej txheem stamping xws li khoov, kos duab, sib sau, thiab lwm yam. Nws tuaj yeem ua incisions, trimming, thiab lwm yam. . Blanking yog dav siv nyob rau hauv industrial sectors xws li tsheb, khoom siv hauv tsev, electronics, instrumentation, machinery, railways, kev sib txuas lus, tshuaj, lub teeb kev lag luam, textiles, thiab aerospace. Blanking ua nyiaj rau li 50% mus rau 60% ntawm tag nrho cov txheej txheem stamping.
Txoj kev tsim
Khoov: Ib txoj hauv kev tsim cov yas uas khoov cov ntawv hlau, cov kav dej thiab cov profiles rau hauv qee cov ces kaum, curvatures thiab cov duab. Khoov yog ib qho ntawm cov txheej txheem tseem ceeb uas tau siv dav hauv kev tsim cov khoom stamping. Kev khoov ntawm cov ntaub ntawv hlau yog qhov tseem ceeb ntawm cov txheej txheem elastic-yas deformation. Tom qab unloading, lub workpiece yuav tsim cov kev taw qhia elastic rov qab deformation, uas yog hu ua springback. Springback cuam tshuam rau qhov tseeb ntawm cov khoom ua haujlwm thiab yog qhov teeb meem tseem ceeb uas yuav tsum tau xav txog hauv cov txheej txheem khoov.
Daim duab sib sib zog nqus: sib sib zog nqus nqus, tseem hu ua kev kos duab lossis calendering, yog txoj kev ua haujlwm stamping uas siv cov pwm tig lub tiaj tiaj uas tau txais tom qab xuas nrig ntaus rau hauv qhov qhib qhov khoob. Cov txheej txheem sib sib zog nqus yuav siv tau los ua cylindrical, stepped, conical, kheej kheej, lub thawv-zoo li tus thiab lwm yam irregular-shaped nyias-walled qhov chaw. Yog tias ua ke nrog lwm cov txheej txheem stamping, cov khoom uas muaj cov duab tsis tshua muaj siab tuaj yeem tsim tau. Nyob rau hauv stamping ntau lawm, muaj ntau hom sib sib zog nqus kos qhov chaw. Vim lawv cov yam ntxwv geometric sib txawv, muaj ntau qhov sib txawv lossis tseem ceeb sib txawv hauv qhov chaw ntawm qhov chaw deformation, qhov xwm txheej ntawm deformation, kev faib tawm ntawm deformation, thiab lub xeev kev ntxhov siab thiab kev faib tawm ntawm txhua qhov ntawm qhov khoob. Yog li ntawd, txoj kev txiav txim siab ntawm cov txheej txheem tsis, tus naj npawb thiab cov txheej txheem ntawm cov txheej txheem, thiab cov qauv tsim pwm thiab cov txheej txheem sib txawv. Raws li cov yam ntxwv ntawm deformation mechanics, ntau qhov sib sib zog nqus tau muab faib ua plaub hom: ncaj-walled teb lub cev (cylindrical qhov chaw), ncaj-walled tsis-rotating lub cev (lub thawv-zoo li lub cev), nkhaus nto rotary lub cev (curved. deg duab qhov chaw) thiab nkhaus nto tsis-rotating lub cev. hom.
Kev kos duab yog siv lub zog tensile rau daim ntawv los ntawm kev kos duab tuag, uas ua rau tsis muaj zog tensile thiab tensile strain hauv daim ntawv. Tom qab ntawd qhov sib koom ua ke ntawm daim ntawv thiab cov duab kos tuag maj mam nthuav mus txog rau thaum nws tag nrho haum rau daim duab qauv nto. Cov khoom siv ntawm kev kos duab yog tsim los tsim cov tawv nqaij hyperbolic uas nws cov ntaub ntawv muaj qee yam yas, thaj chaw loj, hloov maj mam thiab du curvature, thiab cov kev xav tau zoo (qhov tseeb tsos, du streamlines, thiab ruaj khov zoo). Vim tias cov txheej txheem cov cuab yeej siv thiab cov cuab yeej siv hauv kev kos duab yog qhov yooj yim, tus nqi qis thiab qhov yooj yim yog siab; Txawm li cas los xij, qhov kev siv cov khoom siv thiab cov khoom tsim tau tsawg.
Spinning yog txheej txheem kev sib hloov hlau. Thaum lub sij hawm ua, cov dawb paug rotates nrog lub spinning tuag los yog lub taub hau spinning nquag rotates nyob ib ncig ntawm lub dawb paug thiab lub spinning tuag. Lub taub hau spinning ua rau pub mov txav mus rau mandrel thiab qhov khoob, ua rau tsis tu ncua hauv zos deformation ntawm qhov khoob kom tau txais qhov xav tau kev sib hloov hollow. lub cev qhov chaw.
Shaping yog siv cov cuab yeej sib tsoo tsim los ua kom rov zoo li qub ntawm cov khoom. Feem ntau pom nyob rau hauv qhov chaw nias, elastic taw, thiab lwm yam. Rau qee cov ntaub ntawv uas elastic thiab tsis tuaj yeem lav qhov zoo ntawm ib zaug molding, reprocessing yog siv.
Bulging yog ib txoj kev ua haujlwm uas siv cov pwm kom ncab thiab nyias daim ntawv kom nce qhov chaw hauv cheeb tsam kom tau txais qhov chaw. Cov khoom siv feem ntau muaj xws li nyem txoj kev, bulging ntawm cylindrical (los yog tubular) blanks thiab nro ntawm lub tiaj tiaj. Bulging tuaj yeem ua tiav los ntawm ntau txoj kev, xws li txhav tuag bulging, roj hmab bulging thiab hydraulic bulging.
Flanging yog ib txoj kev ua yas uas khoov ntug ntawm lub phaj nyias nyias los yog cov khoom siv nyob rau hauv qhov chaw nqaim ntawm ntug ntawm lub qhov ua ntej ua ntej ntawm qhov khoob rau hauv ib txoj kab ntsug raws kab nkhaus lossis kab ncaj. Flanging feem ntau yog siv los ntxiv dag zog rau cov npoo ntawm qhov chaw, tshem tawm cov npoo npoo, thiab tsim cov khoom sib dhos thiab txuas nrog lwm qhov chaw lossis peb-seem qhov chaw nrog cov duab thiab cov duab tshwj xeeb thiab qhov chaw tsim nyog, thiab tib lub sijhawm txhim kho qhov tawv nqaij ntu. Nws kuj tseem siv tau los ua ib txoj hauv kev los tswj cov kab nrib pleb lossis wrinkles thaum tsim cov ntawv loj. Yog li ntawd, nws yog dav siv nyob rau hauv industrial sectors xws li tsheb, aviation, aerospace, electronics thiab khoom siv hauv tsev.
Kev txo qis yog ib txoj kev stamping uas txo qhov txoj kab uas hla ntawm qhov qhib kawg ntawm ib tug stretched flangeless hollow daim los yog raj dawb paug. Txoj kab uas hla ntawm qhov kawg ntawm lub workpiece ua ntej thiab tom qab shrinkage yuav tsum tsis txhob loj heev, txwv tsis pub cov khoom kawg yuav wrinkle vim yog compression deformation loj heev. Yog li ntawd, shrinking lub caj dab qhib los ntawm ib tug loj txoj kab uas hla mus rau ib tug me me txoj kab uas hla feem ntau yuav tsum tau ntau lub caj dab qhib.
