Dab tsi yog Cov Piercing Techniques ntawm Laser Tej Tshuab?

Tam sim no, feem ntau siv thermal txiav txoj hauv CNC txiav daim ntawv thov hauv kev ua lag luam yog nplaim txiav thiab plasma txiav. Txawm li cas los xij, los ntawm kev xav ntawm kev txiav zoo thiab txiav cov nyhuv, laser txiav tshuab yuav tsum tau txhim kho ntau yam piv rau yav dhau los. Xav txog tias lub hauv paus ntsiab lus ntawm kev txiav laser yog ntau dua li cov nplaim taws thiab cov ntshav txiav, Kuv ntseeg tias ntau lub lag luam thiab cov neeg siv tsis muaj kev nkag siab ntau. Hauv qab no yog ib qho kev ntsuam xyuas los ntawm Yiqiang editor rau koj:
1. Txiav thiab perforation tshuab
Txhua qhov kev siv thev naus laus zis thev naus laus zis, tshwj tsis yog qee qhov xwm txheej uas nws tuaj yeem pib ntawm ntug ntawm lub rooj tsavxwm, feem ntau yuav tsum muaj lub qhov me me rau ntawm lub rooj tsavxwm. Yav dhau los, ntawm laser stamping composite machines, ib lub punch tau siv los xuas lub qhov ua ntej, thiab tom qab ntawd siv lub laser pib txiav los ntawm lub qhov me me. Muaj ob txoj hauv kev rau tho laser txiav tshuab yam tsis muaj cov khoom siv stamping:
Blasting perforation - Cov khoom yog irradiated los ntawm ib tug nruam laser los tsim ib lub qhov nyob rau hauv nruab nrab, thiab ces cov khoom molten yog sai sai tshem tawm los ntawm ib tug oxygen flow coaxial nrog lub laser beam los tsim ib lub qhov. Qhov loj ntawm lub qhov feem ntau cuam tshuam nrog lub thickness ntawm lub phaj, thiab qhov nruab nrab txoj kab uas hla ntawm lub blasting qhov yog ib nrab ntawm lub phaj thickness. Yog li ntawd, rau cov phaj tuab, lub qhov blasting txoj kab uas hla yog loj dua thiab tsis ncig, thiab yuav tsum tsis txhob siv rau ntawm qhov chaw uas yuav tsum tau ua kom raug. Nws tsuas yog siv tau rau ntawm cov khoom pov tseg xwb. Tsis tas li ntawd, vim tib lub zog oxygen siv thaum lub sij hawm perforation thaum lub sij hawm txiav, muaj qhov tseem ceeb splashing.
Pulse perforation - Siv lub ncov fais fab mem tes laser kom yaj lossis vaporize ib qho me me ntawm cov khoom siv, huab cua lossis nitrogen feem ntau yog siv los ua cov pa roj kom txo tau qhov nthuav dav ntawm lub qhov vim exothermic oxidation, thiab cov pa roj siab qis dua cov pa oxygen. siab thaum txiav. Txhua pulse ntawm laser tsuas yog tsim me me particle dav hlau uas maj nkag mus, yog li lub sij hawm perforation rau tuab daim hlau yuav siv sij hawm ob peb feeb. Thaum lub perforation tiav lawm, tam sim ntawd hloov cov auxiliary gas nrog oxygen rau txiav. Ua li no, txoj kab uas hla ntawm lub perforation yog me me, thiab qhov zoo ntawm lub perforation yog zoo dua li ntawm blasting perforation. Lub laser siv rau lub hom phiaj no yuav tsum tsis tsuas yog muaj lub zog tso zis ntau; Qhov tseem ceeb tshaj plaws, cov yam ntxwv ntawm lub cev thiab qhov chaw ntawm lub nqaj ua rau nws nyuaj rau kev hloov pauv dav dav CO2 lasers kom tau raws li qhov yuav tsum tau ua ntawm laser txiav. Tsis tas li ntawd, pulse perforation kuj yuav tsum muaj qhov ua tau zoo ntawm kev tswj cov pa roj kom ua tiav hom roj, hloov roj siab, thiab tswj lub sijhawm perforation.
Nyob rau hauv cov ntaub ntawv ntawm kev siv pulse piercing, thiaj li yuav tau txais high-zoo txiav, kev hloov technology los ntawm pulse piercing thaum lub workpiece nyob ruaj ruaj mus rau qhov ceev ceev nruam txiav ntawm workpiece yuav tsum tau ua tiag tiag. Hauv txoj kev xav, feem ntau nws tuaj yeem hloov pauv qhov kev txiav ntawm ntu nrawm, xws li focal length, nozzle txoj haujlwm, roj siab, thiab lwm yam, tab sis qhov tseeb, nws tsis zoo li yuav hloov cov xwm txheej no vim lub sijhawm luv luv. Txoj kev tseem ceeb uas siv hauv kev tsim khoom lag luam yog hloov pauv lub zog nruab nrab ntawm laser, uas yog qhov ua tau zoo dua. Txoj kev tshwj xeeb yog hloov lub mem tes dav; Hloov cov mem tes zaus; Ib txhij hloov cov mem tes dav thiab zaus.
2. Kev soj ntsuam ntawm deformation ntawm qhov me me (nrog me me txoj kab uas hla thiab phaj thickness) thaum txiav thiab ua
Qhov no yog vim hais tias cov cuab yeej siv tshuab (tsuas yog rau lub tshuab hluav taws xob laser txiav) tsis siv cov khoom tawg thaum ua cov qhov me me, tab sis siv cov mem tes perforation (mos puncture). Qhov no ua rau lub zog laser ua kom muaj zog heev hauv thaj chaw me me, scorching cov chaw tsis ua haujlwm, ua rau deformation ntawm lub qhov thiab cuam tshuam rau kev ua haujlwm zoo. Nyob rau ntawm no, peb yuav tsum hloov lub pulse perforation (mos puncture) txoj kev mus rau lub blasting perforation (zoo tib yam puncture) txoj kev nyob rau hauv qhov kev pab cuam los daws nws. Rau lub zog me me laser txiav tshuab, qhov rov qab yog qhov tseeb. Thaum lub qhov me me ua, mem tes perforation yuav tsum tau siv kom ua tiav qhov zoo dua.
