cov khoom twg yog qhov zoo tshaj plaws rau pwm?

Cov pwm ua tau raws li cov kev cai ntawm kev ua haujlwm

1. Hnav tsis kam

Thaum lub blanks yog plastically deformed nyob rau hauv lub pwm kab noj hniav, nws ntws thiab swb raws saum npoo ntawm cov kab noj hniav, ua rau kev sib txhuam ua txhaum nruab nrab ntawm cov kab noj hniav thiab seem, uas ua rau cov pwm kom swb vim hnav. Yog li ntawd, qhov hnav tsis kam ntawm cov khoom siv yog ib qho tseem ceeb tshaj plaws thiab tseem ceeb ntawm cov pwm.

Hardness yog lub ntsiab tseem ceeb cuam tshuam rau hnav tsis kam. Feem ntau, siab dua hardness ntawm pwm qhov chaw, qhov tsawg dua qhov hnav thiab qhov zoo dua qhov hnav tsis kam. Ntxiv thiab, hnav tsis kam kuj muaj feem xyuam rau hom, kom muaj nuj nqis, lub cev, qhov loj thiab kev faib tawm ntawm carbide hauv cov khoom.

2. Lub zog

Kev ua haujlwm ntawm cov pwm feem ntau yog qhov tsis zoo, thiab qee qhov ntawm lawv feem ntau raug cuam tshuam loj heev, uas ua rau brittle puas. Txhawm rau tiv thaiv kev tawg sai sai ntawm pwm qhov chaw thaum ua haujlwm, pwm yuav tsum muaj lub zog siab thiab toughness.

Lub toughness ntawm pwm mas nyob ntawm cov ntsiab lus carbon, grain loj thiab lub koom haum lub xeev ntawm cov khoom.

3. Kev qaug zog tawg ua haujlwm

Hauv cov txheej txheem pwm ua haujlwm, nyob rau hauv lub sij hawm ntev kev txiav txim ntawm cyclic kev nyuaj siab, nkees nkees feem ntau tshwm sim. Nws cov ntaub ntawv suav nrog qis-zog ntau yam cuam tshuam qaug zog tawg, tensile qaug zog tawg, hu rau qaug zog tawg, thiab khoov qaug zog tawg.

Kev qaug zog tawg ntawm pwm feem ntau yog nyob ntawm nws lub zog, tawv, tawv, thiab cov ntsiab lus ntawm kev suav nrog hauv cov khoom siv.

4. Kev kub siab ua haujlwm

Thaum ua hauj lwm kub ntawm pwm yog siab dua, lub hardness thiab lub zog yuav txo, ua rau ntxov hnav ntawm pwm lossis yas deformation thiab tsis ua haujlwm. Vim tias cov khoom siv pwm yuav tsum muaj kev tiv thaiv tempering siab, los xyuas kom meej tias cov pwm muaj lub siab tawv thiab lub zog ntawm kev ua haujlwm kub.

5. Tiv thaiv kom txias thiab kub qaug zog

Qee cov pwm yog nyob rau hauv lub xeev ntawm rov ua cua sov thiab txias thaum lub sijhawm ua haujlwm, uas ua rau lub ntsej muag ntawm cov kab noj hniav yuav tsum tau rub thiab siab los hloov cov kev ntxhov siab, ua rau nto tawg thiab tev, nce kev sib txhuam, inhibiting yas deformation, thiab txo qhov raug qhov tseeb. Pwm tsis ua haujlwm. Thaum tshav kub kub thiab txias qaug zog yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm kev ua tsis tiav ntawm cov pwm ua haujlwm kub, thiab hom pwm no yuav tsum muaj kev tiv thaiv siab rau txias thiab kub qaug zog.

6. Corrosion kuj

Thaum qee cov pwm xws li yas pwm ua haujlwm, vim muaj cov tshuaj chlorine, fluorine thiab lwm yam khoom hauv plastics, muaj zog corrosive gases xws li hci thiab hf yuav daws tau tom qab cua sov, uas yuav erode nto ntawm pwm kab noj hniav, nce nws saum npoo roughness, thiab aggravate hnav tsis ua hauj lwm.

Thib ob、cov pwm ua tau raws li cov txheej txheem kev ua tau zoo

Kev tsim cov pwm feem ntau muaj ntau yam txheej txheem xws li forging, txiav, thiab kev kho cua sov. Txhawm rau kom ntseeg tau qhov zoo ntawm pwm tsim thiab txo cov nqi tsim khoom, cov khoom yuav tsum muaj zoo forgeability, machinability, hardenability, hardenability thiab grindability; nws kuj yuav tsum muaj me me oxidation, decarburization rhiab heev thiab quenching Deformation thiab cracking nyiam.

1. Forgeability

Nws muaj tsawg kub forging deformation kuj, zoo plasticity, dav forging kub ntau yam, tsawg nyiam ntawm forging cracking thiab txias cracking thiab nag lossis daus ntawm network carbides.

2. Annealing txheej txheem

Lub spheroidizing annealing kub ntau yog dav, lub annealing hardness yog tsawg, qhov kev hloov pauv yog me me, thiab spheroidizing tus nqi yog siab.

3. Machineability

Tus nqi txiav yog loj, cov cuab yeej poob qis, thiab machined nto roughness yog tsawg.

4. rhiab heev rau oxidation thiab decarburization

Thaum tshav kub kub, oxidation kuj zoo, lub decarburization ceev yog qeeb, nws tsis rhiab rau qhov nruab nrab cua sov, thiab nyiam pitting yog me me.

5. Hardenability

Tom qab quenching, nws muaj uniform thiab siab hardness.

6. Hardenability

Tom qab quenching, tuaj yeem tau txais ib txheej txheej hardened, uas tuaj yeem hardened los ntawm kev siv ib qho me me quenching nruab nrab.

7. Kev xav ntawm quenching deformation thiab tawg

Pa quenching muaj me me hloov pauv, puab warping, me ntsis distortion, thiab tsis tshua muaj siab ntawm qhov txawv txav. Pa quenching muaj tsawg rhiab heev rau cracking, thiab yog insensitive rau quenching kub thiab workpiece puab.

8. Grindability

Cov txheeb ze hnav ntawm lub log sib tsoo yog me me, thiab qhov kev txwv ntawm kev sib tsoo yam tsis muaj hlawv yog qhov loj. Nws tsis rhiab rau qhov zoo ntawm lub log sib tsoo thiab cua txias, thiab nws tsis yog ib qho yooj yim los ua abrasion thiab sib tsoo tawg.

Peb, cov pwm ua tau raws li kev xav tau ntawm kev lag luam

Thaum xaiv cov ntaub ntawv rau cov pwm, lub hauv paus ntsiab lus ntawm kev lag luam yuav tsum tau txiav txim siab kom txo cov nqi tsim khoom ntau li ntau tau. Yog li ntawd, nyob rau hauv lub premise ntawm satisfying qhov kev ua tau zoo, thawj xaiv tus nqi qis, carbon hlau tuaj yeem siv tsis muaj hlau alloy, thiab cov khoom siv hauv tsev tuaj yeem siv yam tsis muaj cov khoom siv txawv teb chaws. Ntxiv thiab, kev tsim khoom thiab kev xa khoom ntawm lub khw yuav tsum tau txiav txim siab thaum xaiv cov khoom siv. Cov qib steel xaiv yuav tsum yog tsawg thiab muaj zog li sai tau .

Cov txheej txheem txhaj tshuaj molding muaj kev cuam tshuam rau cov tsos thiab cov khoom siv ntawm cov khoom yas. Txhua tus txheej txheem txheej txheem parameter cuam tshuam ib leeg thiab tsis ywj pheej. Qhov tsis xws luag ntawm qee cov khoom yog qhov tshwm sim ntawm kev sib nrig sib cuam tshuam.
