Qhov tseeb qhov tseeb ntawmblanking qhov chawyog hais txog qhov sib txawv ntawm qhov loj me ntawm qhov khoob khoob thiab qhov loj me ntawm daim duab.Qhov sib txawv me me, qhov tseeb dua.Qhov sib txawv no suav nrog ob qhov sib txawv: ib qho yog qhov sib txawv ntawm qhov khoob ntawm qhov punch lossis tuag loj, thiab lwm qhov yog qhov sib txawv ntawm qhov tuag nws tus kheej.
Kev cuam tshuam ntawm blanking clearance raulub zog blanking, unloading force, thawb lub zog thiab jacking force
Nrog rau qhov nce ntawm kev tshem tawm, lub tensile kev nyuaj siab ntawm cov khoom thaum lub sij hawm blanking yuav nce, cov khoom yog ib qho yooj yim rau tawg thiab cais, thiab lub blanking quab yuam yuav raug txo mus rau ib qho twg.Txawm li cas los xij, nyob rau hauv ib txwm muaj xwm txheej, kev tshem tawm tsis cuam tshuam rau lub zog txiav.
Qhov kev tshem tawm muaj qhov cuam tshuam loj rau kev tshem tawm lub zog thiab thawb lub zog.Lub unloading quab yuam thiab thawb lub zog yuav txo nrog qhov nce ntawm clearance.Feem ntau, thaum qhov kev tshem tawm ib leeg nce mus rau 15% ~ 25% ntawm cov khoom tuab, lub zog thauj khoom yuav luag poob rau xoom.Txawm li cas los xij, thaum qhov sib txawv tseem nce ntxiv, qhov burr yuav nce, thiab lub zog tshem tawm thiab ejector quab yuam yuav nce sai.
Kev cuam tshuam ntawm Blanking Clearance ntawm Tuag Lub Neej
Cov ntaub ntawv tsis ua haujlwm ntawm stamping tuag feem ntau suav nrog hnav, chipping, deformation, expansion thiab tawg.
Lub blanking quab yuam yog tsuas yog concentrated nyob rau hauv txiav ntug ntawm punch thiab tuag.Lub ntug deformation thiab qhov kawg lub ntsej muag hnav yog nruj, txawm tias ntug tawg.
Yog li ntawd, txhawm rau txo qhov hnav ntawm cov txiv neej thiab poj niam tuag thiab ua rau lub neej ntev ntawm kev tuag, nws yog ib qho tsim nyog yuav tsum tau txais kev pom zoo kom muaj txiaj ntsig loj dua ntawm qhov chaw ua haujlwm kom ntseeg tau qhov zoo ntawm cov khoom seem.Yog tias kev tshem tawm me me, nws yog qhov tsim nyog los txhim kho lub hardness thiab hnav tsis kam ntawm qhov tuag, txhim kho qhov raug ntawm qhov tuag, thiab siv lubrication zoo thaum lub sij hawm blanking kom txo tau hnav.
Kev txiav txim siab ntawm tus nqi clearance tsim nyog
Yog li ntawd, nyob rau hauv qhov tseeb zus tau tej cov stamping, ib tug ntau yam tus nqi yog teev rau lub clearance mas raws li cov kev xav tau ntawm peb yam tseem ceeb ntawm seem zoo, seem raug thiab tuag lub neej ntawm blanking qhov chaw.Qhov kev tshem tawm no yog hu ua kev tshem tawm tsim nyog.Qhov tsawg kawg nkaus tus nqi ntawm qhov no yog hu ua yam tsawg kawg nkaus tsim nyog clearance (Zmin), thiab tus nqi siab tshaj yog hu ua qhov siab tshaj plaws tsim nyog clearance (Zmax).Xav tias qhov hnav hauv cov txheej txheem tsim khoom ua rau kev tshem tawm loj dua, qhov tsawg kawg nkaus tsim nyog clearance (Zmin) yuav tsum tau txais kev pom zoo thaum tsim thiab tsim pwm tshiab.
