Loj-scale machining nyob rau hauv tus txheej txheem ntawm kev ua hauj lwm nyob rau hauv thiaj li yuav ua tau raws li cov kev cai ntawm nws cov neeg muas zaub workpiece, nyob rau hauv kev siv ntawm lub workpiece yuav tsum tau zoo positioned nyob rau hauv ib tug taag txoj hauj lwm ntawm lub tshuab cuab tam, thiaj li yuav zam lub workpiece nyob rau hauv lub machining txheej txheem. los ntawm kev txiav quab yuam, lub ntiajteb txawj nqus thiab lwm yam sab nraud quab yuam thiab hloov chaw, nws yog ib qho tsim nyog yuav tsum tau siv ib qho kev sib txuas rau clamp lub workpiece, kom nws txoj hauj lwm ruaj khov tsis hloov. Dab tsi yog qhov zoo ntawm kev siv cov khoom sib txawv rau kev ua haujlwm loj?
Qhov zoo ntawm kev siv Q235A (A3 steel) rau machining loj
Lub ntsiab kom zoo dua ntawm machining loj nyob rau hauv lub lag luam ntawm ib tug tej yam kev kawm ntawm plasticity, toughness thiab vuam kev ua tau zoo, tag nrho cov khoom muaj ib tug tej yam stamping kev kawm thiab txias dabtsi yog khoov kev ua tau zoo, nyob rau hauv kev siv ntawm txhua yam qhov chaw thiab vuam qauv yog tsuas yog siv nyob rau hauv cov kev cai ntawm qhov tsawg dua qhov xav tau, xws li nws txoj hlua khi, txuas rods, pins, shafts, screws, ceev, brackets, bases, thiab lwm yam.
Qhov zoo ntawm kev siv 40Cr rau machining loj
Loj-scale machining nyob rau hauv ib tug tej yam degree tom qab lub tempering txheej txheem yuav muaj zoo heev tag nrho cov neeg kho tshuab zog thiab tsis tshua muaj kub cuam tshuam toughness thiab tsis tshua muaj notch rhiab heev, zoo hardenability. Cov roj txias tuaj yeem tau txais thaum lub zog siab dua, cov dej txias txias yog qhov ua rau tawg. Zoo machinability tom qab tempering los yog quenching, tab sis tsis zoo weldability thiab yooj yim los tsim cov kab nrib pleb.
Nyob rau hauv kev siv cov qauv mas tom qab tempering kev kho mob rau nws manufacturing txheej txheem ntawm nws ceev txav ntawm cov neeg kho tshuab qhov chaw, xws li nws cov cuab yeej cuab tam lub zog, shafts, worm gears, thiab lwm yam.. nrog lub siab tawv thiab hnav tsis kam, xws li lub zog, ncej, spindles, crankshafts, mandrels, tes tsho, pins, txuas rods, thiab lwm yam.
Tom qab quenching thiab nruab nrab-kub tempering rau kev tsim khoom ntawm hnyav-duty, nruab nrab-ceev mechanical qhov chaw, xws li roj twj tso kua mis rotors, sliders, zog, spindles, thiab lwm yam. Tom qab quenching thiab low-temperature tempering rau kev tsim cov khoom hnyav, Tsis tshua muaj kev cuam tshuam, hnav-resistant mechanical Cheebtsam, xws li worm gears, spindles, shafts, thiab lwm yam. Carbonitriding txheej txheem uas yog tom qab kev tsim cov loj loj, tsis tshua muaj kub cuam tshuam toughness ntawm kis tau tus mob qhov chaw, xws li shafts, gears, thiab lwm yam.
Qhov zoo ntawm kev siv 45 # rau kev ua cov tshuab loj
45 # yog cov khoom siv zoo carbon steel, yog tam sim no feem ntau siv nruab nrab carbon tempered steel.
Nyob rau hauv tus txheej txheem ntawm kev khiav hauj lwm yuav muaj zoo heev tag nrho cov neeg kho tshuab zog, nyob rau hauv kev siv ntawm nws tsis tshua muaj hardenability, dej quenching yog ib qho yooj yim los tsim cov kab nrib pleb, welded qhov chaw yuav tsum tau preheated ua ntej welding, tom qab welding yuav tsum tau annealed.
Feem ntau yog siv rau: kev tsim khoom ntawm cov khoom siv hluav taws xob muaj zog, xws li impellers, pistons, shafts, gears, racks, worm gears, thiab lwm yam.
