1.Dab tsi yog cov khoom tseem ceeb?
Cov Khoom Siv Ntau Tshaj: Nrog rau kev txhim kho ntawm lub tsheb sib zog, daim ntawv thov ntawm ultra- siab- lub zog steel (xws li thib peb- tiam siab - lub zog steel) tau nce zuj zus. Cov ntaub ntawv no muaj lub zog siab heev, ua rau muaj kev sib txhuam loj heev thiab kev sib cuag ntawm qhov chaw tuag thaum lub sij hawm txias stamping, ua rau muaj kev nrawm nrawm ntawm kev tuag.
Kev huv huv thiab nplaum: Yog tias cov khoom tsis huv, xws li cov hmoov hlau, oxide nplai, lossis cov xuab zeb, ua raws li qhov txias ntawm -rolled coil, cov khoom nyuaj no yuav ua zoo li abrasives thaum lub sij hawm stamping, ua rau hnyav hnyav ntawm qhov tuag thiab cov ntawv hlau, ncaj qha khawb qhov tuag.
Khoom Thickness Deviation: Yog hais tias daim ntawv hlau thickness fluctuates ho (tshwj xeeb tshaj yog tsis zoo sib txawv), qhov tseeb blanking clearance tej zaum yuav tshaj qhov tsim nyog ntau yam, uas ua rau cov burrs loj heev. Cov burrs, nyob rau hauv lem, exacerbate tuag hnav.
2.Dab tsi yog yam muaj feem xyuam rau pwm tsim?
Pwm hardness tsis txaus thiab hnav tsis kam: Yog hais tias qhov hardness ntawm qhov ua hauj lwm ntawm cov pwm yog tsawg heev, nws hnav tsis kam yuav tsis zoo. Piv txwv li, ib rooj plaub tau qhia tias thaum cov txheej txheej hardness qis dua HRC 50, hnav tsis kam txo los ntawm 40%. Xaiv qhov zoo dua - cov khoom pwm zoo (xws li hmoov metallurgy steel ASP-23) lossis ua kom cov tawv tawv ntawm qhov tseem ceeb rau 58-62 HRC tuaj yeem txhim kho qhov no zoo.
3.Dab tsi yog qhov tshwm sim ntawm pwm tsim thiab tshem tawm?
Qhov me me dhau los yog loj dhau qhov kev tshem tawm: Yog tias qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm Qhov me me dhau qhov clearance intensifies extrusion; loj heev clearance yuav tsim ntau burrs, uas nyob rau hauv lem yuav ua puas lub tuag.
Kev ntxhov siab nyob rau hauv kev tsim: Lub kaum ntse ntse los yog kev hloov pauv me me ntau dhau ntawm qhov chaw tuag yuav ua rau muaj kev ntxhov siab hauv cheeb tsam, uas yuav tsis yooj yim ua rau tawg, tab sis kuj ua rau hnav hauv cheeb tsam ntawd.
4.Dab tsi yog qhov tshwm sim ntawm kev kho pwm tsis zoo?
Txawm hais tias cov khoom siv tuag zoo li cas, tsis muaj kev kho kom zoo (xws li nitriding, PVD txheej, TD txheej, thiab lwm yam), nws tsis yooj yim los tiv thaiv kev sib txhuam hnyav thaum lub sij hawm siab - lub zog steel stamping. Piv txwv li, Kobe Steel's HKS-G thev naus laus zis yog kev kho qhov chaw kho qhov chaw tshwj xeeb tsim los daws cov teeb meem ntawm kev tuag hnav hauv siab - lub zog steel stamping. Cov ntaub ntawv Toolox kuj xav tau kev kho kom zoo ntawm nitriding kom ua tau zoo heev hnav.
5.Dab tsi yog cov txheej txheem txheej txheem?
Tsis zoo lubrication: Qhov no yog ib qho ntawm feem ntau ua rau pwm hnav. Lubricant zoo cais cov pwm thiab cov ntawv hlau los ntawm kev sib cuag ncaj qha, nqa tawm kev sib txhuam kub. Yog tias cov roj nplua nyeem raug xaiv tsis raug, thov tsis sib npaug, lossis tsis txaus, qhov sib txhuam coefficient ntawm kev sib txhuam yuav nce siab, ua rau kub siab, ua rau cov pwm saum npoo ntawm cov khoom muag muag thiab ua kom nrawm nrawm. Lub lubrication zoo tuaj yeem ua rau lub neej pwm ntev ob peb zaug lossis ntau tshaj kaum zaug.
Qhov kub thiab txias hauv zos nce thiab adhesion: Nyob rau hauv kev kub siab thiab zawv zawg kev sib txhuam, qhov kub hauv cheeb tsam hauv cheeb tsam nce siab, uas yuav ua rau cov khoom hloov ntawm cov pwm thiab cov ntawv hlau, ua "nplaum nodules." Cov nodules yog ib qho nyuaj heev thiab tuaj yeem khawb tau tom qab hla cov ntawv hlau (piv txwv li, roughening). Lawv kuj sawv cev rau qhov poob ntawm cov khoom pwm, piv txwv li, "thaum hnav."
Cov txheej txheem tsis tsim nyog: Piv txwv li, cov khoom siv khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Kev kub stamping ntau dhau kuj ua rau cov cua sov sib sau ua ke, exacerbating hnav.
