Vim lawv cov qauv tsim tshwj xeeb thiab kev ua haujlwm zoo, cov txheej txheem tsim khoom rau cov khoom tsis yog - cov khoom siv kho vajtse yuav tsum sib npaug qhov tseeb thiab yooj yim los xyuas kom muaj kev hloov pauv tau zoo thiab txhim khu kev qha los ntawm kev thov mus rau cov khoom tiav. Piv nrog rau kev sib dhos kab ua haujlwm ntawm cov qauv tsim, cov txheej txheem tsis yog- cov txheej txheem txheej txheem qhia txog theem kev tshuaj xyuas thiab kev hloov kho kom zoo los tiv thaiv kev ua haujlwm sib txawv thiab cov yam ntxwv geometric nyuaj.
Cov txheej txheem pib nrog kev xav tau tsom xam thiab kev npaj ua haujlwm. Thaum tau txais txoj haujlwm, hauv -Kev sib txuas lus tob nrog tus neeg siv yog qhov tsim nyog los qhia meej txog qhov chaw siv, thauj khoom, txwv tsis pub siv, thiab qhov yuav tsum tau ua kom raug, thiab hloov cov ntaub ntawv no mus rau qhov ntsuas tsim muaj peev xwm. Cov kauj ruam tom ntej yog kev tsim qauv, siv 3D qauv software los ua kom tiav cov duab, thaum ua qhov kev tshawb fawb ua ntej los txheeb xyuas cov teeb meem xws li cov kab noj hniav sib sib zog nqus, oblique qhov, thiab cov phab ntsa nyias, muab lub hauv paus rau cov txheej txheem tom ntej.
Cov txheej txheem npaj theem tsom mus rau kev tsim cov txheej txheem machining raws li cov khoom siv thiab cov yam ntxwv ntawm cov qauv. Feem ntau, daim ntawv dawb paug (piv txwv li, bar Tshuag, ntawv hlau, lossis forgings) yog txiav txim siab ua ntej, ua raws li roughing, semi- tiav, thiab ua tiav cov txheej txheem. Rau qhov tsis xwm yeem contours thiab complex nta, ntau -axis CNC khoom thiab tshwj xeeb fixtures yog feem ntau yuav tsum tau los txo tus naj npawb ntawm clamping hauj lwm thiab cumulative yuam kev. Cov ntaub ntawv txheej txheem yuav tsum qhia meej meej hom cuab yeej, txiav tsis, cov txheej txheem txias, thiab cov ntsiab lus tshuaj xyuas. Kev kuaj simulation yuav tsum tau ua thaum tsim nyog los kwv yees machining deformation thiab kev nyuaj siab concentration txaus ntshai.
Kev siv ntau lawm ua raws li lub hauv paus ntsiab lus ntawm "los ntawm kev ntxhib los ua kom tiav, kauj ruam-los ntawm- kauj ruam tswj." Rough machining tshem tawm feem ntau ntawm cov khoom siv ntau dhau, tso cov duab yooj yim ntawm qhov; semi-finishing kho lub datum thiab reserves tiav nyiaj pub dawb; Kev ua tiav nruj me ntsis ua raws li kev kos duab kam rau ua, tsom rau qhov tseem ceeb mating nto thiab geometrical raug. Thaum lub sij hawm machining, thawj -txheej tshuaj ntsuam thiab soj ntsuam xyuas yuav tsum tau muab coj los siv kom sai li sai tau txheeb xyuas thiab kho cov teeb meem xws li cov cuab yeej hnav thiab cov cuab yeej cuab tam hloov pauv.
Kev kho deg thiab kev soj ntsuam zaum kawg yog cov kauj ruam tseem ceeb hauv txoj kev kaw. Nyob ntawm qhov chaw pabcuam, cov txheej txheem xws li oxidation, electroplating, txau, lossis passivation raug xaiv los txhim kho corrosion, hnav tsis kam, lossis kev ua haujlwm zoo. Kev tshuaj xyuas zaum kawg suav nrog kev tshuaj xyuas tag nrho, kev ntsuas qhov ntsuas geometrical kam rau ua, thiab cov kev sim ua haujlwm tsim nyog (xws li kev sib khi thiab ntsuas kev thauj khoom), nrog rau cov ntaub ntawv tshawb xyuas tau khaws cia. Cov khoom tsim nyog raug xa mus tom qab kev tiv thaiv ntim kom ntseeg tau tias lawv tsis raug puas tsuaj thaum thauj.
Zuag qhia tag nrho, cov txheej txheem tsis yog{0}} cov txheej txheem tsim khoom kho vajtse yog raws li kev hloov pauv ntawm qhov xav tau, hauv paus hauv cov txheej txheem kev npaj, thiab nyob rau hauv theem ua tiav thiab tag nrho - txheej txheem tswj kom zoo. Los ntawm kev sib cuam tshuam kev tswj hwm thiab kev siv tshuab, nws ua tiav siab - xa khoom zoo ntawm cov khoom siv kho kom haum, muab kev txhawb nqa zoo rau kev tsim khoom siab - kawg.
