Puas yog SPCC daim ntawv haum rau stamping?

Q: Puas yog SPCC daim ntawv haum rau stamping? Nws puas tuaj yeem siv los ua qhov sib sib zog nqus- kos?
A: Nws yog qhov tsim nyog rau "tsim yooj yim" (xws li kos duab ntiav, xuas nrig ntaus, thiab blanking), xws li cov teeb ci thiab cov khoom siv me me. Txawm li cas los xij, nws tsis haum rau kev kos duab sib sib zog nqus (xws li thermos khob plhaub thiab lub tsheb roj tso tsheb hlau luam) vim tias qhov elongation ntawm SPCC (Ntau dua lossis sib npaug li 28%) yog qis dua qhov sib sib zog nqus -kos duab qib SPCE (Ntau dua lossis sib npaug rau 34%), ua rau nws muaj feem rau caj dab thiab tawg thaum sib sib zog nqus nqus.
Q: Puas yog SPCC daim ntawv yuav tsum tau xeb - tshem tawm ua ntej ua haujlwm? Nws raug tshem tawm li cas?
A: Newly muas SPCC daim ntawv (packaged nrog anti- xeb roj) tsis tas yuav xeb tshem tawm. Yog tias xeb tshwm sim vim qhov chaw cia tsis raug (xws li saum npoo), koj tuaj yeem siv: ① Kev tshem tawm cov hlau tsis huv (sandpaper polishing, hlau txhuam); ② Kev tshem tawm cov tshuaj xeb (immersion hauv dilute hydrochloric acid, ua raws li dej ntxuav thiab ziab). Yog hais tias xeb yog tob, nws raug nquahu kom khawb nws kom tsis txhob cuam tshuam kev ua haujlwm raug.
Q: SPCC daim ntawv puas tuaj yeem kho qhov chaw? Cov kev kho mob li cas?
A: Yog. Cov kev kho mob saum npoo muaj xws li: ① Painting / hmoov txheej (txhim kho xeb thiab zoo li qub, siv rau cov khoom vaj tse thiab rooj tog zaum); ② Electroplating (galvanizing thiab chrome plating, tiv thaiv xeb thiab zoo nkauj, siv rau cov khoom siv kho vajtse); ③ Phosphating (txhim kho xim zaj duab xis adhesion, siv ua ntej- kho ua ntej pleev xim); ④ Passivation (chav kub tiv thaiv xeb, siv rau ib nrab-cov khoom tiav nyob rau hauv ib ntus cia).
Q: Dab tsi ua rau SPCC daim ntawv deformation tom qab ua tiav? Yuav daws tau li cas?
A: Feem ntau ua rau: ① Tsis txaus txias rolling kev nyuaj siab nyem (xws li, tsis txaus annealing); ② Kev ua haujlwm tsis raug (xws li, kev khoov ntau dhau, tsis sib xws stamping siab); Cov kev daws teeb meem: ① Ua kom muaj kev ntxhov siab annealing (tuav ntawm 200-300℃rau 1-2 teev) ua ntej ua; ② Kho cov txheej txheem ua haujlwm (txo qis khoov nrawm, sib npaug sib npaug ntawm lub zog stamping).
V. Application Scenarios
Q: Dab tsi yog daim ntawv thov tseem ceeb rau SPCC daim ntawv? Dab tsi yog cov khoom lag luam? A: Cov ntawv thov tseem ceeb yog nyob rau hauv "tsis yog- kos duab sib sib zog nqus, nruab nrab thiab tsis muaj zog" cov xwm txheej: ① Kev lag luam kho vajtse: hinges, brackets, screws thiab washers, toolboxes; ② Kev lag luam khoom siv hauv tsev: lub tshuab ntxhua khaub ncaws, lub tshuab cua txias sab nraum zoov, lub tub yees rov qab panels; ③ Electronics kev lag luam: charger vaj tse, Circuit Court board brackets; ④ Kev tsim kho kev lag luam: lub teeb steel keels, zoo nkauj me me; ⑤ Automotive kev lag luam: yooj yim tsis yog-load- cov kabmob (xws li lub qhov rooj sab hauv vaj huam sib luag).
