yuav ua li cas xaiv pwm kom zoo thiab cov ntaub ntawv ntawm kev tuag

Pwm xaiv
Kev xaiv cov khoom siv tuag yog qhov txuas tseem ceeb hauv tag nrho cov txheej txheem tuag. Kev xaiv cov khoom tuag yuav tsum ua kom tau raws li peb lub hauv paus ntsiab lus, tuag kom tau raws li qhov hnav tsis kam, lub zog thiab toughness thiab lwm yam yuav tsum tau ua haujlwm, tuag kom tau raws li cov txheej txheem, thiab tuag yuav tsum tau raws li kev siv nyiaj txiag. Lub folding mob yuav tsum tau
1. Hnav tsis kam. Thaum lub blanks yog plastically denatured nyob rau hauv lub tuag kab noj hniav, nws ntws thiab swb raws qhov chaw ntawm qhov tuag kab noj hniav, ua rau muaj kev sib txhuam loj ntawm cov kab noj hniav tuag thiab qhov khoob, uas ua rau tsis ua hauj lwm ntawm kev tuag 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 khoom tuag. Hardness yog lub ntsiab tseem ceeb cuam tshuam rau hnav tsis kam. Feem ntau, qhov siab dua qhov hardness ntawm cov khoom seem, qhov tsawg dua qhov hnav, qhov zoo dua qhov hnav tsis kam. Ntxiv thiab, hnav tsis kam kuj muaj feem xyuam rau hom, tus nqi, lub cev, qhov loj thiab kev faib tawm ntawm carbide hauv cov khoom.
2. Muaj zog toughness, tuag ua hauj lwm tej yam kev mob feem ntau phem heev, qee qhov feem ntau dais qhov cuam tshuam loj dua, ua rau brittle puas. Txhawm rau tiv thaiv qhov tuag qhov chaw hauv kev ua haujlwm ntawm kev tawg sai sai, tuag yuav tsum muaj zog thiab toughness. Lub toughness ntawm cov tuag tsuas yog nyob ntawm cov ntsiab lus carbon, grain loj thiab microstructure ntawm cov khoom.
3. Kev qaug zog tawg ua haujlwm, tuag ua hauj lwm nyob rau hauv lub sij hawm ntev ntawm cyclic kev nyuaj siab, feem ntau ua rau qaug zog tawg. Nws cov ntaub ntawv suav nrog qis-zog rov ua rau qaug zog tawg, tensile qaug zog tawg, hu rau qaug zog tawg thiab khoov qaug zog tawg. Kev qaug zog thiab pob txha muaj zog ntawm cov tuag 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, yuav txo qhov hardness thiab lub zog, ua rau pwm thaum ntxov hnav lossis yas deformation thiab tsis ua haujlwm. Yog li ntawd, cov khoom siv pwm yuav tsum muaj kev tiv thaiv tempering siab, nyob rau hauv thiaj li yuav xyuas kom meej tias cov pwm nyob rau hauv lub kub ua hauj lwm, nrog rau siab dua hardness thiab lub zog.
5. Tiv thaiv kom txias thiab kub qaug zog. Qee qhov tuag tau rhuab thiab txias dua hauv cov txheej txheem ua haujlwm, uas ua rau saum npoo ntawm

Cov kab noj hniav tuag yuav raug nro thiab siab strain stress, ua rau nto tawg thiab spalling, nce kev sib txhuam, thiab inhibits yas deformation, txo Dimensional raug, ua rau pwm tsis ua hauj lwm. Mob khaub thuas thiab kub qaug zog yog ib qho ntawm cov tsis ua haujlwm tseem ceeb ntawm kev ua haujlwm kub tuag, thiab zoo li no tuag yuav tsum muaj siab txias thiab kub qaug zog tiv thaiv. 6. Corrosion kuj, qee cov pwm xws li yas pwm hauv kev ua haujlwm, vim muaj cov tshuaj chlorine, fluorine thiab lwm yam khoom hauv yas, Thaum tshav kub kub tom qab decomposition tawm HCI, HF thiab lwm yam muaj zog corrosive gas, erosion pwm kab noj hniav nto, ua kom nws nto roughness, nce hnav tsis ua hauj lwm.
1) Cov khoom ntawm cov khoom tseem ceeb ntawm cov pwm yog xaiv tsis raug. Cov khoom muaj kev ua haujlwm tsis zoo thiab tsis hnav-resistant; cov hlau tuag tsis tau ua kom zoo dua qub thiab muaj ntau qhov tsis xws luag; convex thiab concave pwm, forging blanks thiab txheej txheem forging tsis zoo tag nrho, thiab muaj zais qhov phom sij ntawm kev kho cua sov.

2) Tuag qauv tsim teeb meem, tus qauv tuag yog tsis tsim nyog. Lub slender punch tsis yog tsim los nrog cov cuab yeej txhawb nqa, qhov chaw nres nkoj tawm yog tsis du thiab piles, thiab lub zog tawm yog loj heev, thiab cov xuas nrig ntaus yog raug rau qhov sib ntxiv load.

3) Cov pwm ua txheej txheem yog imperfect, uas yog mas manifested nyob rau hauv lub tsis zoo sab hauv zoo ntawm lub convex thiab concave tuag forging blanks, thiab cov cuab yeej kho cua sov thiab cov txheej txheem muaj teeb meem, ua rau lub convex thiab concave pwm tsis tiav quenched, soft me ntsis thiab uneven hardness. Qee zaum microcracks lossis txawm tias tawg, kev sib tsoo thiab polishing tsis nyob hauv qhov chaw, thiab tus nqi nto roughness yog loj heev.

4) Tsis muaj lubrication lossis lubrication tab sis tsis zoo
