Cov hauv paus ntsiab lus thiab qhov ua tau ntawm qhov tensile
Kev kos duab sib sib zog nqus yog cov txheej txheem uas tuaj yeem deform steel daim hlau lossis lwm yam khoom tsis-ferrous. Nrog nws, cov txheej txheem ntawm elongation thiab compression deformation tuaj yeem muab rau tib lub sijhawm, feem ntau yog siv kom tau txais qhov hollow, cylindrical, thawv, zoo li tus lossis khob zoo li cov khoom.
Qhov sib sib zog nqus ntawm cov ntawv hlau yog ua los ntawm kev nce qib lossis hloov pauv tuag, thiab tso cai rau kev tsim ntau yam khoom nrog cov kab noj hniav sib sib zog nqus, xws li: nws pib lub cev, cov khoom siv hauv tsev, rooj tog zaum thiab cov khoom siv hluav taws xob cov ntsiab lus, ntau lub ntim xws li cov kaus poom, cov kaus poom, thiab yog li ntawd. Feem ntau, qhov kev ua haujlwm tshwj xeeb no tso cai rau cov khoom pwm tuaj yeem ua rau hauv ib daim ntawv tsis muaj kev sib koom ua ke.
Sib sib zog nqus nqus qhov chaw yuav muaj qhov zoo dua lwm yam txheej txheem uas lawv tuaj yeem tau txais ferrous lossis non-ferrous cov khoom siv nrog cov duab elongated, tsis muaj wrinkles, thiab siab deformation, yog li tuav cov khoom zoo.
Daim duab sib sib zog nqus / sib sib zog nqus qhov chaw VS casting
Kev kos duab yog txheej txheem ua haujlwm txias, thaum casting yog txheej txheem ua haujlwm kub. Los ntawm fusion, cov khoom yog rhuab mus rau hauv lub xeev ua kua, uas yog ces poured rau hauv tshwj xeeb pwm qhov twg nws kho thiab yuav siv sij hawm nyob rau hauv lub xav tau geometry. Castings yog cov khoom tau los ntawm cov txheej txheem no.
Cov txheej txheem Casting tsis haum rau txhua hom ntaub ntawv thiab nws yog ib txwm tsim nyog los xyuas qhov fusion thiab castability ntawm cov hlau yuav cam khwb cia. Feem ntau, nws yog siv los tsim cov khoom thiab cov khoom siv rau faucets, tes, kas fes txiag, carburetor, li qub, thiab lwm yam.
Tsim cov khoom ua haujlwm tau los ntawm cov duab sib sib zog nqus feem ntau txo cov nqi tsev, txhim kho cov khoom tsim tau thiab zoo, thiab feem ntau txo cov nqi tsim khoom. Tsis yog qhov xav tsis thoob, ntau qhov chaw uas siv los ntawm kev tsim cov casting tau hloov dua siab tshiab rau hauv cov duab sib sib zog nqus.
Cov khoom ntws thiab tswj
Cov lus tseem ceeb ntawm tensile qhov chaw yog cov khoom ntws thiab tswj.
Qhov peb txhais tau li cas los ntawm kev ntws yog li cas cov khoom yuav tsum deform thiaj li yuav rov ua dua rau hauv qhov xav tau. Xav txog kev siv lub siab los tso cov khoom siv roj hmab loj hauv qhov xav tau. Cov duab no muab lub tswv yim ntawm yuav ua li cas tuag thiab punch ua lub luag haujlwm hauv deforming daim ntawv.
Qhov kev tswj ntawm ntws, los yog qhov twg cov khoom yuav tsum mus thiab qhov twg nws tsis mus, yog lwm yam tseem ceeb nam thiab yog guaranteed los ntawm kev siv ib tug welt xovxwm.
Deep stretch pieces: Dab tsi yog qhov deal?
Thaum qhov tob ntawm qhov workpiece yuav tsum tau ntau dua nws qhov dav, cov txheej txheem hu ua qhov sib sib zog nqus nqus. Kev vam meej nyob ntawm ntau yam, suav nrog:
Geometry ntawm cov ntsiab lus;
Khoom hom, thickness, thiab mechanical zog: qhov tob ntawm daim duab, qhov zoo dua ntawm cov khoom, thiab ntau dua qhov deformation tso cai ua ntej tawg;
Xovxwm ceev: Nws yuav tsum tso cai rau cov khoom ntws;
Daim duab vojvoog;
Kev kos duab piv: yog ib qho ntawm cov hauv paus ntsiab lus txiav txim siab seb tus lej ntawm cov txheej txheem yuav tsum tau ua los ntawm pwm;
Punch thiab tuag nto kho;
Lubricants: Ua ke nrog qhov chaw tiav, txo cov coefficient ntawm kev sib txhuam thiab ua kom cov khoom swb zoo dua;
Lub siab ntawm lub tshuab nias;
Qhov sib txawv ntawm lub punch thiab tuag.
Tag nrho cov xwm txheej no, ua ke nrog kev paub dhau los hauv kev ua haujlwm, tau ua rau muaj kev vam meej ntawm kev sib sib zog nqus nqus pwm.
Sib sib zog nqus nqus tuag: Kev ruaj ntseg zoo
Stretchings yog cov txheej txheem kev tshaj lij uas pom nws cov lus qhia zoo tshaj plaws hauv cov khoom lag luam uas xav tau cov khoom lag luam nrog cov txiaj ntsig siab, qhov zoo ntawm qhov chaw, thiab cov duab peb sab, thiab feem ntau nyuaj heev. Thaum ua tiav, cov duab tuaj yeem pom tau tias muaj kev khoov ntxiv thiab kev ua haujlwm shearing kom tau txais cov khoom tiav.
