Dab tsi yog cov qauv kev ua haujlwm rau pwm 3D luam ntawv?

Siv rau kev txhaj tshuaj molding, tshuab molding, extrusion, tuag casting los yog forging, melting, stamping, stretching, thiab lwm yam pwm thiab cov cuab yeej. Nyob rau hauv luv luv, pwm yog cov cuab yeej tsim cov khoom. Cov cuab yeej muaj ntau qhov sib txawv, thiab cov pwm sib txawv muaj qhov sib txawv. Nws tsuas yog ua cov duab ntawm cov khoom los ntawm kev hloov lub cev lub cev ntawm cov khoom molding. Peb feem ntau siv pwm los ua ib co tes boards.
1, Abrasion tsis kam
Thaum lub steel billet undergoes yas deformation nyob rau hauv pwm kab noj hniav, lub steel billet ntws thiab swb raws cov pwm kab noj hniav nto, ua rau muaj kev sib txhuam loj ntawm cov pwm kab noj hniav nto thiab steel billet, ua rau pwm tsis ua hauj lwm vim hnav. Yog li ntawd, hnav tsis kam ntawm cov ntaub ntawv yog ib qho ntawm cov pwm tseem ceeb ntawm cov khoom. Hardness yog lub ntsiab tseem ceeb cuam tshuam rau hnav tsis kam.
2, Muaj zog toughness
Kev ua haujlwm ntawm 3D luam ntawv qauv feem ntau tsis zoo, thiab qee qhov feem ntau dais qhov cuam tshuam loj, ua rau tawg tawg. Txhawm rau tiv thaiv kev tawg sai sai ntawm cov pwm pwm, pwm yuav tsum muaj lub zog siab thiab toughness. Lub toughness ntawm pwm mas nyob ntawm cov ntsiab lus carbon, grain loj, thiab microstructure ntawm cov khoom.
3, qaug zog tawg ua haujlwm
Thaum lub sij hawm 3D luam ntawv ntawm pwm, qaug zog tawg feem ntau tshwm sim nyob rau hauv lub sij hawm ntev cyclic kev nyuaj siab. Nws cov ntaub ntawv muaj xws li tsis tshua muaj zog ntau cuam tshuam qaug zog pob txha, tensile fatigue fracture, hu rau qaug zog tawg, thiab khoov qaug zog tawg.
4, Kev ua haujlwm siab kub
Thaum cov pwm ua hauj lwm kub siab, qhov hardness thiab lub zog txo, ua rau thaum ntxov hnav los yog yas deformation thiab tsis ua hauj lwm ntawm pwm. Yog li ntawd, cov khoom siv pwm yuav tsum muaj lub siab tempering tsis kam ua kom ntseeg tau tias cov pwm muaj lub siab tawv thiab lub zog ntawm kev ua haujlwm kub.
