Stud welding zinc tshem tawm txheej txheem - laser, drilling thiab milling

Lub hom phiaj tseem ceeb ntawm kev tshem tawm zinc ua ntej lub vuam yog txhawm rau tshem tawm cov zinc txheej hauv qhov chaw vuam, tiv thaiv qhov tsis xws luag xws li qhov pores thiab cov kab nrib pleb tshwm sim los ntawm zinc vapor thaum lub vuam txheej txheem, thiab xyuas kom lub vuam lub zog ntawm cov stud thiab cov khoom siv hauv paus.
Qhov sib txawv tseem ceeb (Cov Ntsiab Cai thiab Kev Sib Raug Zoo) hauv stud vuam scenarios
Laser zinc tshem tawm
Laser zinc tshem tawm yog ib qho uas tsis yog -kev tiv thaiv nto tshuab siv lub siab - zog- laser beam kom irradiate zinc txheej rau ntawm qhov chaw ntawm lub workpiece. Lub zog laser yog absorbed sai sai los ntawm zinc txheej, ua rau nws tam sim ntawd kub mus rau lub melting point los yog boiling point, ua rau vaporization tev los yog thermal shock detachment, yog li ua tiav qhov sib cais ntawm zinc txheej los ntawm substrate.
Lub hauv paus ntsiab lus: Lub teeb tsom teeb laser precisely vaporizes/peel- tawm ntawm zinc txheej ntawm qhov chaw vuam. Nws tsis yog-kev sib cuag, nrog lub tshav kub me me heev- thaj chaw cuam tshuam (< 0.1mm), and does not damage the base material or the positioning accuracy of the stud.
Tau tshaj cov xwm txheej: M3-M10 me me- txoj kab uas hla studs, ntom taw tes, nyias- phab ntsa panels (tsawg dua los yog sib npaug li 1.5mm), precision chassis/cabinets/lub cev lub zog tshiab, thiab lwm yam. Txhawb nqa txoj haujlwm thiab txoj hauv kev, haum rau cov kab ntau lawm.
Cov txiaj ntsig tseem ceeb: Cov ciam teb tshem tawm zinc tuaj yeem tswj tau (± 0.2mm), tsis muaj kev ntxhov siab, tsis muaj deformation tom qab vuam, thiab tsis xav tau kev sib tsoo thib ob.
Lus Cim: Lub hwj chim (500-1500W fiber ntau laser), defocus npaum li cas thiab scanning ceev yuav tsum tau sib phim kom tsis txhob muaj zog ntau dhau thiab kub kub yaig ntawm lub substrate.
Drilling thiab milling rau zinc tshem tawm
Drilling thiab milling rau kev tshem tawm zinc belongs rau kev sib cuag tshuab txiav tshuab. Los ntawm kev sib hloov kev txiav txim ntawm drilling thiab milling cov cuab yeej, zinc txheej ntawm lub workpiece yog ncaj qha milled thiab tshem tawm. Qhov tseem ceeb, nws yog tev tawm cov zinc txheej los ntawm lub cev quab yuam.
Principle: Three-edge carbide milling cutters are selected. The rotary milling cutter cuts the zinc layer in the welding area, and the contact mechanical removal is adopted. It is suitable for thick zinc layers (>50μm) thiab loj - thaj tsam pretreatment.
Nws muaj zinc tshem tawm kev ua haujlwm siab thiab tsim nyog rau batch ua ntawm thaj chaw loj thiab tuab zinc txheej. Cov cuab yeej siv tus nqi kuj qis dua li cov khoom siv laser.
Cov txiaj ntsig tseem ceeb: Kev tshem tawm cov zinc siab (2 mus rau 3 npaug ntawm lub laser), tsuas yog cov milling cutters yuav tsum tau siv raws li cov khoom siv, tsim nyog rau cov xwm txheej uas tsis tshua muaj qhov tseeb thiab cov txheej txheem sib tsoo tom ntej.
Kev ceev faj: Tswj qhov kev sib hloov ceev (3000-6000rpm) thiab pub tus nqi ntawm 0.1mm / r. Qhov tob txiav yuav tsum yog me ntsis tob tshaj qhov tuab ntawm zinc txheej.
Los xaus
Laser zinc tshem tawm yog tsim rau siab -precision, automated thiab nyias-walled/irregular- zoo li qhov chaw. Nws yog haum rau nyias zinc txheej (5-50 μm) thiab yog nyiam rau M3-M10 me-inch studs
Drilling thiab milling rau kev tshem tawm zinc yog tsim rau tuab zinc txheej (50-200μm) thiab qis- nqi batch scenarios, thiab yog nyiam rau loj-inch studs ntawm M12 thiab siab dua
Hauv kev xaus, ob qho tib si laser thiab drilling thiab milling txoj kev rau kev tshem tawm zinc muaj lawv tus kheej zoo thiab yuav tsum tau yoog raws li cov xwm txheej tshwj xeeb.
