I. Yam ntxwv ntawm Ultra-Thin Parts Stamping Microforming Process

Ultra{0}}thin ntu stamping belongs rau cov txheej txheem microforming. Nws cov yam ntxwv tshwj xeeb hauv kev tsim khoom tiag tiag yog raws li hauv qab no:

1. High- tswj qhov tseeb: Lub thickness ntawm ultra- cov ntaub ntawv nyias yog tswj ntawm 20-200μm, thiab qhov sib txawv ntawm qhov yuav tsum tau tswj nyob rau hauv ± 1μm. Qhov tseeb ntawm qhov chaw ntawm cov khoom siv stamping yuav tsum tsawg dua lossis sib npaug li ± 0.5μm, thiab qhov hloov pauv ntawm cov txheej txheem tsis sib xws (stamping ceev, siab) yuav tsum tsis pub tshaj ± 3%, kom ntseeg tau tias ruaj khov cov txiaj ntsig.

2. Tsawg txoj kev quab yuam thiab yooj yim deformation tswj: Lub forming quab yuam yuav tsum tau rau ultra-thin seem stamping yog 5-20kN, uas yog ntau tshaj 60% qis dua ib txwm stamping. Qhov no txo ​​cov khoom siv zog thiab hnav, thaum tswj cov khoom deformation nyob rau hauv 5% -10%, zam cov khoom tawg thiab tsis tswj deformation.

3. Cov Khoom Siv Tseem Ceeb: Lub microstructure ntawm ultra- cov ntaub ntawv nyias (xws li ultra- nyias stainless hlau thiab aluminium alloy ntawv ci) muaj qhov cuam tshuam loj rau kev tsim. Nws yog ib qho tsim nyog los ntsuas cov ntaub ntawv elastic- cov khoom yas ua ntej, simulate cov txheej txheem tsim los ntawm kev txheeb xyuas cov ntsiab lus finite, thiab txhim kho cov txheej txheem tsis zoo kom haum rau cov khoom siv.

4. High Repeatability thiab Stability: Microforming txheej txheem yuav tsum pwm repeatability tsawg dua los yog sib npaug rau ± 0.3μm thiab cov khoom repeatability raug tsawg dua los yog sib npaug rau ± 0.5μm kom ntseeg tau tias nyob rau hauv loj ntau lawm, qhov seem sib txawv ntawm txhua qhov ultra- nyias ib feem yog tsawg dua los yog sib npaug rau ± 1μm, thiab kev ua tau zoo.

II. Microstructure Mould Design Adaptation Technology

Raws li qhov yuav tsum tau ua ntawm cov txheej txheem microforming, microstructure pwm tsim yuav tsum tau ua raws li cov txheej txheem. Cov ntsiab lus tshwj xeeb yog cov hauv qab no:

1. Miniaturization ntawm Cov Qauv Dimensions: Raws li lub microscopic geometric yam ntxwv ntawm ultra- nyias qhov chaw, tsim cov punch, tuag, thiab muab tso rau hauv. Qhov tseeb qhov tseeb ntawm cov punch thiab tuag txiav npoo yuav tsum tswj tsis pub dhau ± 0.3μm, thiab cov cuab yeej muab tso rau qhov tseeb Tsawg dua los yog sib npaug rau ± 0.5μm kom ntseeg tau tias kev sib cuag ntawm cov pwm thiab cov khoom ua haujlwm, tsis txhob muaj kev ntxhov siab thiab cov khoom siv ntau dhau deformation.

2. Micro-machining thev naus laus zis rau pwm nto: Laser micro-machining thiab electrochemical machining technologies yog siv los ua cov txheej txheem pwm zoo, ua tiav qhov roughness Ra tsawg dua lossis sib npaug li 0.2μm. Ib nano-TiN txheej yog siv nrog lub thickness ntawm 0.003-0.008mm, txo cov coefficient ntawm kev sib txhuam kom qis dua 0.08, txo tensile tsis kam, txhim kho qhov zoo ntawm qhov chaw stamped, thiab txuas cov pwm kev pab cuam lub neej mus rau ntau tshaj 500,000 cycles.

3. Pwm rigidity thiab elasticity ua ke tsim: Finite element tsom xam yog siv los ua kom zoo dua cov khoom pwm thiab cov txheej txheem layout. Cov pwm siv ultra-zoo grain pwm hlau, nqus tsev-quenched kom ua tau ib tug hardness ntawm HRC62-65, xyuas kom pwm rigidity. Ib qho elastic buffer qauv yog ntxiv rau tus Tsov tus tw ntawm lub punch, nrog ib tug tsis mob stroke ntawm 0.5-1 hli, buffering kev ntxhov siab peaks thaum lub sij hawm stamping txheej txheem, txo cov kev ntxhov siab nyob rau hauv lub zos los ntawm 20% -30%, thiab txo qhov chaw nyob rau hauv cracking thiab deformation ntawm ultra-nyias qhov chaw.

4. Multifunctional composite pwm tsim: Tus tsim tsim integrates positioning, kho thiab ua hauj lwm rau hauv ib tug composite micro- qauv pwm nrog 4-6 micro-chaw nres tsheb. Ntau cov txheej txheem tuaj yeem ua tiav hauv ib qho kev stamping, txo qhov superposition ntawm kev ua yuam kev ntawm cov txheej txheem, paub qhov nruam stamping, thiab ua tiav lub voj voog ntau lawm ntawm 20-30 zaug / feeb. Qhov ntev ntev ntawm cov khoom stamped yog ruaj khov nyob rau hauv ± 1μm.
