Muab piv nrog castings thiab kev zam txim, stampings yog nyias, teeb hnyav, lub teeb thiab muaj zog. Kev thim nyiaj tuaj yeem tsim cov khoom ua haujlwm nrog cov neeg xiam oob khab, qhaub qhauj, kev ua haujlwm, lossis flanging uas tsis yoojyim siv los tsim lawv cov tsis txaus siab. Vim yog siv cov pwm pluaj, qhov tseeb ntawm cov khoom ua haujlwm tuaj yeem ncav cuag cov micrometers, thiab qhov rov ua dua thiab kev qhia meej yog qhov zoo ib yam. Lub qhov zes thiab cov naiskhu muaj peev xwm muab punched tawm. Cold stampings feem ntau tsis txiav, los yog yuav tsum tau tsuas yog ib qho nyiaj tsawg. Qhov tseeb thiab qhov chaw ntawm qhov chaw kub kub yog qhov qis dua cov khoom ntawm qhov chaw txias, tab sis lawv tseem zoo dua castings thiab kev zam txim, thiab cov nyiaj machining tsawg.
Stamping yog ib txoj kev siv ntau dhau los. Siv cov tshuaj molds, tshwjxeeb ntau ntau paab pwm, nws muaj peevxwm ua kom tiav ntau yam kev ua haujlwm ntawm ib qho xovxwm (ib qho chaw nres tsheb lossis ntau qhov chaw nres tsheb) mus rau kev ua haujlwm thiab kev ncajncees. Tiaj, blanking, automatic qhuav ntawm txoj kev ua thiab xov. Muaj kev ua haujlwm siab, cov haujlwm ua haujlwm zoo thiab cov nqi tsim khoom tsawg, nws tuaj yeem ua tau ntau pua npaug ntawm ib feeb. Piv nrog rau lwm txoj kev ntawm kev ua vaj ua tus ua thiab kev ua cov yas, kev thwj cim muaj ntau qhov tshwj xeeb ntawm kev lag luam thiab kev lag luam. Qhov kev ua tau zoo yog raws li nram no.
(1) Lub thwj cim muaj kev ua haujlwm siab, kev lag luam yooj yim thiab kev ua kom yooj yim ntawm mechanization thiab automation. Qhov no yog vim kev thwj cim yog ua tiav los ntawm txoj kev tuag thiab cov khoom xuas nrig ntaus. Tus cwj pwm ntawm cov xov xwm niaj hnub tuaj yeem ncav cuag ntau zaus ntawm kaum tawm ntawm ib feeb, qhov kev kub ntxhov ceev tuaj yeem ncav cuag pua pua lossis txawm txhiab lub sij hawm hauv ib feeb, thiab txhua tus mob stroke yog koj tuaj yeem tau txais cov punch.
(2) Txij thaum tuag tag rau qhov loj thiab cov ntaub ntawv ntawm qhov chaw stamping thaum lub sij hawm thwj, thiab feem ntau tsis tua qhov zoo ntawm qhov chaw seem stamping, lub neej ntawm kev tuag yog feem ntau ntev, yog li qhov kev cuam tshuam zoo yog ruaj khov, yog qhov zoo, thiab nws muaj "tib yam" Cov Cwj Pwm.
(3) Lub thim dej muaj peev xwm ua tau ntau yam thiab ntau yam, xws li stopwatches me me raws li cov teev, loj li cov kab ntev longitudinal, daim npog, thiab lwm yam, ntxiv rau cov dej deformation uas ua rau cov khoom siv thaum lub thawb, lub zog ntawm stamping thiab lub nruj yog siab.
(4) Cov thwj cim feem ntau tsis tsim khoom, cov khoom siv tsawg dua, thiab tsis muaj lwm yam khoom siv cua sov. Yog li ntawd, nws yog ib qho khoom txuag thiab kev txuag hluav taws xob, thiab qhov nqi ntawm cov khoom seem hauv qis yog tsawg.
Vim yog qhov zoo tshaj plaws ntawm kev thev ua txoj haujlwm, kev thwj rau khoom muaj ntau hom kev siv hauv ntau cov teb ntawm lub tebchaws. Piv txwv, muaj kev sib tw thiab kev ua lag luam hauv kev tsav tsheb, aviation, ua tub rog, machinery, agricultural machinery, electronics, cov ntaub ntawv, kev tsheb nqaj hlau, kev xa xov thiab xa xov, tsheb thauj mus los, tshuaj, khoom siv kho mob, khoom siv hauv tsev thiab lub teeb ci. Tsuas yog nws siv los ntawm kev lag luam tag nrho, tab sis txhua leej txhua tus muaj kev sib cuag nrog cov khoom siv stamping. Muaj ntau ntau yam khoom loj, nruab nrab thiab me me nyob hauv dav hlau, tsheb ciav hlau, tsheb thiab tsheb laij teb. Lub cev tsheb, thav duab thiab kos yog tag nrho cov nyiaj tawm. Raws li cov ntawv tshawb fawb tau tshaj tawm, 80 feem pua ntawm cov tsheb kauj vab, tshuab xaws thiab watches yog cov thwj cim; 90% ntawm cov TV, cov kaw suab thiab cov koob thaij duab yog cov thwj cim; muaj cov tais diav khoom noj, steel refining boilers, enamel bowls thiab stainless steel cutlery. Tag nrho cov khoom siv stamping siv pwm; Txawm tias lub xov tooj ntawm lub computer tsis muaj cov thwj rau khoom.
