Muaj cov cuab yeej siv hluav taws xob kub-melt fastening nyob rau hauv kev lag luam fastener, uas tsis tas yuav tsum tau qhib lub qhov, thiab tuaj yeem ncaj qha tapping nyob rau hauv lub kaw profile kom paub qhov kev sib txuas. Hauv kev lag luam tsheb xws li BMW, Mercedes-Benz thiab Audi tau siv cov thev naus laus zis no, thiab ntau thiab ntau daim ntawv thov. Yog li cas qhov no yog technology? Dab tsi yog qhov zoo thiab nta?
Ua ntej ntawm tag nrho cov, kuv xav qhia ib lub tswv yim rau koj, cov txheej txheem "flow drilling screw" (lwm lub npe: kub-melt self-tapping / kub-melt fastening system). Hauv lus Askiv, qee qhov tau muab txhais ua Flow drill Screws (FDS), thiab qee qhov raug txhais ua Flow Form Screws (FFS), thaum "flow laum ntswj" yog hais txog cov txheej txheem kev sib txuas ntawm kev sib hloov ceev, nws tus kheej tapping thiab zaum kawg nruj. Cov txheej txheem no tuaj yeem paub txog kev sib txuas ntawm kev sib txuas nrog tsawg dua deformation, thiab nws yog txoj hauv kev detachable fastening.
Lub tshuab kub-melt fastening tshuab yog cov txheej txheem txias txias uas ua rau kev sib hloov ceev ntawm lub cev muaj zog los ntawm kev sib tw ceev hauv nruab nrab ntawm cov khoom siv rau cov yas deformation ntawm daim hlau kom txuas nrog vim kev sib txhuam thiab kub, thiab tom qab ntawd nws tus kheej. -tapping thiab screwing.
Thaum pib ntawm cov txheej txheem nruj, cov ntsia hlau kub yaj yog muab tso rau ntawm qhov chaw ntawm txhuas lossis cov ntawv hlau tsis muaj qhov ua ntej, thiab cov kev kub ceev tig cov ntsia hlau ua rau muaj kev poob siab rau ntawm qhov chaw ua haujlwm thaum ua kom muaj kev sib txhuam siab heev, melting cov hlau. Lub hau ntawm cov ntsia hlau ces nkag mus rau hauv cov khoom, tsim ib qho perforation, thiab maj mam kais cov xov. Thaum cov xov raug tsim, lub hau ntswj yog nruj rau lub preset torque.
Kub yaj fastening txheej txheem cov kauj ruam thiab cov txheej txheem piav qhia, suav nrog rau theem: kev sib hloov (cua sov) → nkag mus → los ntawm qhov → tapping → threading → fastening.
Nyob rau hauv thawj theem, lub high-speed rotating lub cev muaj zog tsav lub ntsia hlau mus rau lub nto ntawm lub workpiece, thiab exerts downward axial siab (lub axial quab yuam mus txog rau 1.5kN, thiab kev sib hloov ceev mus txog 8000r / min) , lub taub hau ntsia hlau thiab cov ntawv hlau qhov saum npoo rub thiab ua kom muaj qhov kub thiab txias, qhov kub yog 600 degree ~ 900 degree, cov hlau nyob rau hauv cheeb tsam ze ntawm cov ntsia hlau softens sai, thiab cov khoom siv rhuab txuas ntxiv mus rau taper ntawm lub laum. me ntsis.
Thaum FDS ntsia hlau nkag mus rau hauv cov khoom, feem ntau ntawm cov ntaub ntawv kub-melt hlau cov ntaub ntawv yuav ntws mus rau hauv qab ntawm lub qhov drilled los ua ib tug hlau bushing thickness ntawm 1 ~ 3 zaug. Tighten. Tag nrho cov txheej txheem tsuas yog siv sijhawm 1 ~ 6s los ua kom tiav cov txiaj ntsig txuas txuas, thiab lub zog tuaj yeem ncav cuag 15N·m.
Nyob rau tib lub sijhawm, tom qab FDS ntsia thawv fastened nyob rau hauv qhov chaw, nws yuav nyob twj ywm rau ib lub sij hawm. Nyob rau hauv qhov kev txiav txim ntawm lub rotating torque, ib tug pre-tightening quab yuam yuav raug tsim, uas yuav txhim khu kev ntseeg tau ntawm threaded kev twb kev txuas, muaj peev xwm los tiv thaiv loosening thiab qaug zog lub zog ntawm cov xov, thiab txhim khu lub nruj ntawm kev sib txuas. thiab nruj.
Cov lus nug yog, tam sim no muaj ntau yam kev sib txuas thev naus laus zis hauv kev lag luam tsheb, vim li cas siv txoj kev sib txuas no?
Tam sim no ntau thiab ntau lub tuam txhab tsheb pib siv steel-aluminium hybrid lub cev thav duab qauv, siv engineering plastics thiab cov ntaub ntawv sib xyaw xws li txhuas profiles, aluminium stampings, aluminium castings, thiab carbon fibers, ua ke nrog ntau yam ultra-high-strength steel daim hlau. los hloov cov tsoos steel phaj Cheebtsam los yog cov khoom kom ua tiav lub teeb yuag thiab siab zog lub cev ncej qauv.
Hauv kev lag luam automotive, txoj hauv kev tseem ceeb ntawm kev koom nrog txhuas yog cov tsoos kho tshuab fastening SPR (self-piercing riveting technology) thiab qhov chaw vuam RSW. SPR yog cov txheej txheem muaj zog thiab hloov tau, tab sis vim yog qhov xav tau ntawm ntau hom rivet-rivet ua ke, cov khoom siv kim heev; Txawm hais tias qhov chaw vuam yog ib qho kev paub tab thiab kev lag luam siab, nws raug txwv los ntawm qhov tsis muaj peev xwm txuas cov hlau sib txawv. Ob qho txheej txheem yuav tsum tau nkag mus rau ob sab, uas txwv tsis pub tsim kev tsim.
Yog li ntawd, technology ntawm kub-melt fasteners tau los ua. Daim duab hauv qab no yog cov lus piav qhia ntawm qhov zoo ntawm cov tshuab kub yaj fastening.
Tsis muaj qhov yuav tsum tau ua ntej punching qhov, ib qho kev sib txuas ib leeg, thiab kev sib txuas ntawm kev sib txuas ntawm txhuas qhov chaw thiab txhuas qhov chaw, txhuas qhov chaw thiab steel qhov chaw tuaj yeem ua tiav.
Ntau lub tuam txhab tsheb nyob sab Europe tau pib siv cov tshuab kub-kua nplaum, xws li Jaguar XK thiab X150, Audi R8, A8, TT Coupe, A6, thiab lwm yam; European tsheb hom xws li Nissan, Land Rover, Porsche, BMW, thiab lwm yam kuj tau qhia txog qhov kev sib txuas Craftsmanship: Tus qauv Cadillac CT6 nyuam qhuav pib los ntawm SAIC-GM tau ua tiav thawj qhov chaw ntawm steel-aluminium lub cev-hauv-dawb, sib txuas 11. cov ntaub ntawv sib txawv thiab feem ntau siv cov cuab yeej txuas no.
FDS rau tes yog ua los ntawm cov khoom siv tawv tawv nrog cov mis tshwj xeeb. Kev yuav khoom ntawm hom screws yog tsuas yog los ntawm txawv teb chaws. Txawm hais tias muaj ntau lub tuam txhab tsheb txawv teb chaws tau siv cov cuab yeej fastening no tau ntau xyoo, cov tuam txhab lag luam tsheb uas lawv tus kheej tsis tshua siv. .
