Kub yaj drilling
1. Kub yaj drilling txheej txheem
High-temperature chipless forming thiab kev sib txhuam kub-melt drilling tshuab, hu ua kub-melt drilling tshuab, yog ib hom tshiab ntawm nyias phaj drilling txoj kev. Nws siv lub hauv paus ntsiab lus ntawm kev sib txhuam ntawm cov cua sov tsim los laum lub qhov nrog cov thawj coj ntawm cov phaj-zoo li tus lossis tubular hlau workpieces, uas yog tsim nyob rau hauv ib lub sij hawm thiab tsis muaj drilling chips. Cov txheej txheem no tag nrho hloov cov txheej txheem ntawm vuam (riveting) ceev ntawm nyias-walled workpieces.
2. Kev txhim kho keeb kwm ntawm kub yaj drilling tshuab
Thaum ntxov li xyoo 1923, Mr. VALLIERE, ib tug neeg Fab Kis, tau sim tsim ib lub cuab yeej rau kub-melt drilling ntawm cov ntawv hlau siv lub hauv paus ntsiab lus ntawm kev sib txhuam thaum tshav kub kub.
Tom qab xyoo ntawm kev sim, nws tau ua tiav technically, tab sis tsis muaj peev xwm ua tau hauv cov ntawv thov kev lag luam. Yog vim li cas:
ib. High-strength cemented carbide tseem tsis tau tawm;
b. Qhov tseeb geometry ntawm lub laum me ntsis tsis paub;
c. Pob zeb diamond sib tsoo log tseem tsis tau tawm;
d. Tsis muaj cov cuab yeej siv tshuab uas muaj peev xwm tsim cov duab tshwj xeeb.
Nws siv sijhawm 60 xyoo los daws cov teeb meem saum toj no thiab kev ua lag luam ua tiav ntawm kev xyaum kub yaj.
3. Lub hauv paus ntsiab lus ua haujlwm ntawm cov txheej txheem kub yaj drilling
Kub-melt laum yog ib qho cuab yeej ua los ntawm tshwj xeeb hnav-resistant thiab high-temperature resistant tungsten carbide hard alloy (yog li nws tseem hu ua tungsten steel kub-melt laum los yog cemented carbide kub-melt laum).
Thaum lub high-speed rotating laum me ntsis hu rau saum npoo ntawm lub workpiece thiab siv downward axial siab, lub taub hau ntawm cov kub-melt laum ntsis rub tawm ntawm cov hlau thiab generates kub ntawm 650 degree mus rau 750 degree, uas ua rau cov hlau nyob rau hauv. thaj tsam ntawm qhov kub-melt laum me ntsis soften sai.
Thaum lub qhov kub-melt laum yog extruding thiab nkag mus, lub softened hlau ib feem yog stretched mus rau hauv ib tug hlau pem hauv ntej (tus thawj coj) nrog peb mus rau plaub zaug ntawm thawj thickness. Tag nrho cov txheej txheem tsuas yog siv sijhawm 2-6 vib nas this.
Tus thawj coj no tuaj yeem siv rau extrusion tapping, xov sib sau, uas tuaj yeem ntxiv dag zog rau kev sib txuas, thiab tseem tuaj yeem siv rau kev txhawb nqa, kev sib txuas ntawm caj pas bifurcated, thiab lwm yam.
Vim tias tag nrho cov txheej txheem ntawm cov txheej txheem kub yaj yog cov txheej txheem chip-dawb, cov xov ua tiav tuaj yeem tiv taus siab tensile quab yuam thiab torsion quab yuam, uas tuaj yeem hloov tag nrho cov txheej txheem ntawm drilling tom qab vuam los yog txheej txheem ntawm nias rivet ceev.
4. Kub yaj drilling txheej txheem:
Qhov kub yaj laum tsuas yog kov cov khoom siv thiab muab tso rau, ces nias tawm tsam cov khoom siv nrog lub zog axial siab thiab tshaj tawm.
Kev siv siab thiab ceev ua kom muaj kev sib txhuam ntawm qhov kub ntawm txog 600 degree, uas plasticizes thiab shapes cov khoom. Kub yaj drills nkag mus rau cov ntaub ntawv hauv vib nas this.
Qhov kub-melt laum squeezes cov hlau horizontally thiab vertically, uas txav cov ntaub ntawv down, tsim ib tug bushing. Thaum cov kub yaj laum nkag mus rau hauv cov hlau, lub siab pub yog maj mam txo, thiab tus nqi pub yog maj mam nce.
Tam sim no, cov txheej txheem kub yaj drilling tau tsim ib lub bushing. Cov khoom siv nyob rau hauv qhov kev taw qhia ntawm cov khoom noj yog extruded thiab tsim ib lub rooj voj voog uas tuaj yeem siv rau kev sib khi. Lub rooj voj voog no tuaj yeem raug tshem tawm hauv tib txoj haujlwm los ntawm kev siv lub laum tiaj tus nrog lub txiav ntug ntawm txoj haujlwm ntawm txoj siv laum.
Extrusion kais tuaj yeem siv tam sim ntawd rau chip-dawb tapping ntawm qhov tshwm sim bushing. Txias extrusion tapping nce cov khoom hardness.
Cov ntsiab lus: Kub yaj drills muaj peev xwm tiv taus siab loads thiab torsional pob qij txha. Tsis tas yuav tsum tau drilling qhov, thiab tom qab riveting, los yog vuam ceev.
5. Qhov zoo thiab qhov tsis zoo ntawm kub yaj qhov drilling
Qhov zoo ntawm kub yaj xyaum xyaum:
ib. Qhov siab ntawm lub rooj voj voog yog ntau tshaj peb npaug ntawm cov khoom siv tuab, thiab tuaj yeem tiv taus lub zog loj thiab nruj heev;
b. High precision thiab siab zog, lub qhov drilled yog siab precision.
c. Huv si thiab ib puag ncig tus phooj ywg, tsis muaj los yog me me chips yog generated thaum lub sij hawm ua.
d. Ceev thiab ua haujlwm tau zoo, lub sijhawm ua haujlwm tsuas yog 2 ~ 6 vib nas this.
e. Qhov ntau ntawm cov ntaub ntawv siv tau yog qhov dav heev, nws tsim nyog rau hlau, me me hlau, stainless hlau, txhuas, tooj liab, titanium, hlau nplaum, tshwj xeeb alloys thiab feem ntau ntawm cov ntaub ntawv hlau (tshwj tsis yog tin lossis zinc)
f. Yuav hloov cov txheej txheem kim xws li vuam thiab riveting txiv ntoo.
g. Txhim kho koj cov khoom zoo, txuag koj lub sijhawm ua haujlwm thiab txo koj cov nqi.
Disadvantages ntawm kub yaj xyaum xyaum:
ib. Qhov kub yaj laum tsuas yog tsim nyog rau kev ua cov yeeb nkab nyias nyias, thiab cov khoom siv siab tshaj plaws ntawm qhov drilled tsis tuaj yeem tshaj 12.5mm.
b. Yuav tsum muaj qhov chaw rau kev khiav dej num ntawm cov khoom kub yaj yas deformation.
c. Cov khoom ua tiav yuav tsum muaj peev xwm tiv taus qhov kub thiab txias.
d. Cov ntaub ntawv uas tau txau thiab coated tsis haum rau cov txheej txheem kub-melt drilling.
