Kev tsim qauv ntawm cov khoom lag luam suav nrog ntau cov kauj ruam, thiab sib dhos yog ib ntawm lawv, thiab kev sib dhos feem ntau nce tus nqi. Tam sim no, cov txheej txheem kev lag luam ntau dua suav nrog ob cov txuj ci: 1. Txo cov khoom sib dhos thiab yooj yim los ntawm kev tsim; 2. Xaiv cov txheej txheem sib txuas uas zoo tshaj plaws haum cov khoom thiab qhov zoo tshaj plaws geometric daim foos. Cov hauv qab no yuav qhia tshwj xeeb cov txheej txheem sib txuas uas nquag siv: kev sib txuas, kho tshuab kho, vuam

Ii. Neeg kho tshuab txhim kho
1. Riveting thiab ntsia hlau
Riveting yog kev siv cov rivetts los txuas ob lossis ntau dua workpieces. Piv txwv li, lub qhov rau cov khau raj yog ua los ntawm cov rivete hollow.
Cov yam ntxwv ntawm riveting thiab ntsia thawv:
Kev Txuas Qhov Loj: Unlimitedlaximtly Thickness (hli): {{} Qhov tuab ntawm cov khoom sib txawv: muaj
Kev faib tawm:
1. Nquag riveting. Cov khoom sib xyaw ua ke tuaj yeem tig nrog txhua lwm yam. Nws tsis yog kev sib txuas nruj. 2. Tsau Riveting. Cov khoom sib xyaw ua ke tsis tuaj yeem txav mus nrog txhua lwm yam. Nov yog kev sib txuas nruj. 3. Kaw riveting. Lub rivet seam yog nruj thiab tsis xau roj lossis kua. Nov yog kev sib txuas nruj.
Nqi:
Cov ntaub ntawv rau riveting thiab ntsia hlau yog pheej yig hauv cov khoom me me, nrawm thiab nyiaj txiag thiab kev ua haujlwm tsawg, thiab cov txheej txheem tuaj yeem siv tshuaj.
Cov Khoom Uas Raug:
Ntsia taw nrog: Ntawv, tawv, khaub ncaws, fiberboard. Riveting tau txuas ntxiv mus rau cov dav hlau, tsheb, thiab khoom siv navigation, thiab muaj peev xwm dav.
2. Threaded kho xov paj yog qhov dav dav siv tshem tawm cov qauv sib txuas nrog cov qauv yooj yim, txhim khu kev sib koom zoo, thiab kev sib dhos yooj yim thiab disassembly.
Cov yam ntxwv dav:
Kev Txuas Qhov Loj: Unlimited Qhov Kawg Thickness (hli): Unlimited Txuas Thickness Nws txawv: Yog Cov Khoom Sib Txuas Sib Txuas: Yog
Nqi:
Threaded kho yog pheej yig heev, thiab tag nrho cov txheej txheem ntxig yog phau ntawv. Qhov tsis zoo yog tias nws yog qhov nyuaj rau kev siv tshuab ntau lawm zoo li lwm txoj kev txuas sib txuas (xws li vuam, riveting, Tsevneeg).
Cov Khoom Uas Raug:
Threaded kho tau dav siv hauv engineering tsim, tab sis nws feem ntau yog txwv rau cov khoom uas tau tsim nyog tau txais. Qhov no yog vim tias lwm txoj kev sib txuas tau yooj yim dua thiab tsis txhob xoob cov yaj me me, uas yooj yim rau kev siv tshuab.
3. Lub caij nplooj ntoos hlav txhim kho
Caij nplooj ntoos hlav kho yog qhov yooj yim thiab kev sib txuas ceev. Nws tsis tas yuav cua sov thiab tuaj yeem txuas cov khoom sib txawv. Nws yog ceev thiab pheej yig.

Cov Khoom Uas Raug:
Kev siv lub caij nplooj ntoos hlav kho tau dhau los ua ntau dua thiab cov ntaub ntawv siv tau dav thiab cov duab, tshwj xeeb yog rau kev sib txuas me me lossis cov thawv hlau lossis daim hlau. Pej xeem nyiaj "Neeg Sau Khoom Mechanical engineering", chav nres tsheb roj rau cov engineers!
3. VUAM
Tau qhov twg los: Galveston College
Vuam yog hais txog cov txheej txheem txheej txheem uas siv cua sov lossis siab, lossis ob qho tib si; nrog lossis tsis muaj cov ntaub ntawv muab tub; Yuav kom ua tiav atomic kev sib hais ntawm ob qho sib cais hlau los ua ib qho kev txuas mus tas li.
Cov txheej txheem qhia ntxaws ntxaws qhia yog qhia hauv qab no.
Cov cua kub vuam tseem hu ua cov vuam kub cua kub. Compressed huab cua lossis cov roj hauv plab (feem ntau nitrogen) yog rhuab rau qhov yuav tsum tau kub, thiab tom qab ntawd ob lub vuam txaij, yog li ob lub suab nrov thiab sib xyaw ua ke hauv qab. Cov yas uas muaj kev nkag siab txog cov pa (xws li polyphhatalamide, thiab lwm yam) yuav tsum siv cov roj cua sov, thiab lwm yam plastics feem ntau yuav siv cov huab cua lim. Cov qauv no feem ntau siv rau kev siv cov plastics xws li polyvinyl chloride, polypropene, polyoxymethylene, polystyrene, thiab carbonate.
Kub-nias vuam yog siv cua sov thiab siab mus nias lub hlau hlau thiab cov hlau vuam ua ke. Lub hauv paus ntsiab lus yog siv cua sov thiab siab ua rau cov hlau ua kom zoo nkauj, yog li cov khoom sib tw ua kom puas ntawm cov atoms thiab cov khoom sib tsoo ntawm atoms thiab ua tiav lub hom phiaj ntawm kev ua dab neeg.
Kub phaj vuam adops cov qauv phaj, thiab cua sov ntawm lub tshuab cua sov pauv mus rau qhov chaw cua sov sab sauv thiab qis dua los ntawm cov hluav taws xob cua sov. Qhov saum npoo yog melted, thiab tom qab ntawd lub tshuab cua sov tshuab yog nrawm dua. Tom qab cov khoom siv hluav taws xob sab saud thiab qis dua yog cov cua sov, lub chaw molten yog fused, solidified, thiab ua ke rau hauv ib qho. Tag nrho lub tshuab yog nyob rau hauv daim ntawv ntawm ib daim ntawv, muaj ntawm peb daim hlau: lub sauv sab sauv, thiab yog nruab
Ultrasonic hlau vuam siv siab ntau zaus kev co vuag ntawm vuag los kis rau ob qhov chaw hlau kom muab welfaces kom welded. Nyob rau hauv siab, ob qhov chaw hlau rub tawm tsam ib leeg los ua cov fusion ntawm cov txheej txheem molecular. Nws cov txiaj ntsig tau nrawm, lub zog txuag, muaj zog fusion, kev ua tau zoo, tsis muaj txim taws, thiab ze rau kev ua haujlwm txias; Qhov tsis zoo yog cov welded hlau feem tsis tau tuab heev (feem ntau tsawg dua lossis sib npaug los yog sib npaug ntawm 5 hli), qhov kev xav tau loj dhau, thiab lub siab yuav tsum muaj.
Laser Vuam yog ib txoj kev vuam zoo thiab meej dua uas siv lub siab-lub zog-ntom nthe teeb. Nws yog ib qho ntawm cov tseem ceeb ntawm daim ntawv thov laser kev siv tshuab. Feem ntau, ib lub nqaj txuas ntxiv yog siv los ua kom tiav cov ntaub ntawv sib txuas. Nws cov txheej txheem xim hlau yog zoo heev rau hluav taws xob ci ci, uas yog, lub zog hloov dua siab tshiab tau ua tiav los ntawm "tus qauv" qauv. Qhov kev sib npaug kub hauv qhov kab noj hniav mus txog 2500 0 c. Tshav kub yog pauv los ntawm phab ntsa sab nraud ntawm qhov siab-kub cov kab noj hniav, melting cov hlau nyob ib puag ncig kab noj hniav. Lub qhov me me yog muaj cov chav kub uas tau tsim los ntawm kev txuas mus ntxiv ntawm cov ntaub ntawv phab ntsa hauv qab ntawm cov chaw ruaj khov ntawm lub teeb lub teeb. Lub teeb ci tsis tu ncua nkag mus rau hauv lub qhov me me, thiab cov khoom nyob sab nraum lub qhov me me ntws tsis txuas ntxiv. Raws li lub teeb nqaj tsiv, lub qhov me me yog ib txwm nyob hauv lub xeev ruaj khov ntawm ntws. Lub Molten hlau ua cov kab sib txawv tom qab lub qhov me me tau muab tshem tawm thiab hws, thiab weld yog tsim.
Brazing yog qhov vuam txoj kev vuam uas ua kom cov khoom siv ua kom zoo dua li ntawm qhov chaw ua haujlwm kom ntev dua li ntawm ob qho chaw ua haujlwm), thiab tos kom nws muaj txiaj ntsig zoo ua ntej koom nrog ob qho ua ke. Kev lig kev cai hauv Tebchaws Meskas, qhov kub siab tshaj 800 Degree F (427 Degree C) yog hu ua brazing (nyuaj brazing), thiab vice versa.
Kev tuav ntaub ntawv vuam yog ib txoj kev vuam yog ib txoj kev vuam ua haujlwm los ntawm kev tuav lub teeb, vuam phom lossis sib dhos.
Kev tawm tsam vuam yog ib txoj kev tsim khoom lag luam thiab thev naus laus zis rau kev koom nrog cov hlau lossis lwm cov ntaub ntawv thermoplastic xws li cov cua sov. Nws yog ib txoj kev vuam los ntawm kev thov nias los ntawm cov electrodes tom qab lub workpihab generated los ntawm kev sib chwv ntawm kev sib cuag ntawm cov sib koom tes thiab thaj chaw ib sab.
Kev sib txhuam vuam yog ib qho khoom siv-theem vuam txoj kev uas siv cov tshuab hluav taws xob ua lub zog. Cov cua sov tsim los ntawm kev sib txhuam ntawm qhov kawg ntsej muag ntawm cov workpieces yog siv los ua kom lawv mus txog lub xeev yas, thiab tom qab ntawd lub vuam ua tiav los ntawm kev chim siab.
Electroslag vuam siv cov tsis kam ua kom sov los ntawm kev sib tw ua ke kom yaj, thiab tom qab solidification ntawm cov hlau atoms yog tsim. Thaum pib ntawm vuam hlau yog luv-ciructited nrog lub zeem muag vuam kom pib lub arc, thiab ib qho me me ntawm cov khoom flux txuas ntxiv. Cov cua sov ntawm arc yog siv los yaj nws los ua kua slag. Thaum lub ntsej muag tiv thaiv ib qho tob, kev pub mis ceev ntawm lub vuam hlau yog nce, thiab lub arc yog extinguish, yog li nkag mus rau hauv cov txheej txheem elctercag. Electroslag vuam tsuas yog suav nrog nozzle Electroslag vuam, vuam hluav taws xob vuam, thiab cov pob txha ceev Qub thiab tempered tom qab vuam.
High-furnency vuam (ntau zaus vuam) siv cov khoom ua kom sov li lub zog. Thaum lub sij hawm vuam, cov tsis kam kub los ntawm kev nquag tam sim no nyob rau hauv lub chaw ua haujlwm rau ntawm lub xeev wortpiece yog siv los ua kom muaj kev lom zem, thiab tom qab ntawd kev foob
Riveting hais txog txoj kev ntawm txuas ob daim hlau lossis cov khoom ua ke los ntawm kev kaw qhov hauv lawv cov chaw, tom qab ntawd tso cov rivetts rau hauv, thiab riveting cov rivets nrog rab phom rivet
Kub Melt yog txoj kev sib txuas tom qab muab cua sov rau (cov kua) melting point.
