Micron-theem Precision: Tshaj tawm Cov Txheej Txheem Tsim Khoom Ntawm Lub Tswv Yim Ntawm V3 Infusion Koob

Qhov kev ua tau zoo ntawm V3 Infusion Needle (tsim los ntawm Manners Technology) yog cov hauv paus hauv kev tsim cov txheej txheem uas ua ke nrog kev ua haujlwm siab -kev ua haujlwm zoo, kev tuav cov khoom zoo, thiab kev tswj xyuas nruj. Los ntawm ib tug stainless hlau bar rau ib tug txhim khu kev qha thiab meej koob, cov txheej txheem ntau lawm yog ib qho kev tsim khoom ntawm micron nplai.
Txoj kev tsim khoom pib nrog siab - cov ntaub ntawv bar precision. Cov xaiv stainless hlau 304 bar muaj txoj kab uas hla kam rau ua, ncaj thiab grain loj uas yuav tsum tau ua tib zoo xaiv kom muaj kev ruaj ntseg ntawm kev ua haujlwm tom ntej. Ib qho ntawm cov txheej txheem tseem ceeb yog cov zawv zawg headstock tshuab dhos (Sliding Headstock Lathe) ua, uas tshwj xeeb yog siv Japanese Citizen Cincom L12-1M7 qauv. Hom tshuab no tseem hu ua "Swiss-hom tshuab dhos", tshwj xeeb los ntawm qhov tseeb tias lub thawv spindle tuaj yeem xaub qhov ntev (Z-axis txav), thaum lub cuab yeej kho. Nws yog qhov tshwj xeeb tshaj yog tsim rau kev ua cov ncej slender. Thaum ua cov hexagonal puag ntawm V3 tus pin, cov khoom siv bar yog tig ntawm kev kub ceev thiab thawb rau pem hauv ntej. Ntau cov cuab yeej ua haujlwm ib txhij ua haujlwm xws li tig lub voj voog sab nraud, milling lub hexagon, thiab tapping threads nyob rau hauv kev tswj ntawm kev tswj cov lej. Citizen Cincom L12-1M7 tuaj yeem ua tiav qhov tseeb ntawm ± 0.01mm thiab lub kaum sab xis ntawm ± 0.1 degree, nrog rau qhov roughness ntawm Ra <0.4μm. Qhov no theem ntawm smoothness yuav txo tau kev sib txhuam thaum lub sij hawm xov kev koom tes, kom ib tug du installation thiab txhim khu kev qha sealing nrog lub txhaj tshuaj neeg hlau interface.
Lub shaping ntawm koob tip ib feem yog nyob rau hauv lub swaging technology. Swaging yog txheej txheem chipless forming uas siv ob lossis plaub lub pwm los ua qhov siab - zaus, me me - amplitude radial forging ntawm qhov kawg ntawm rotating lossis nyob ruaj khov raj lossis rods, txo lawv txoj kab uas hla thiab hloov lawv cov duab. Ob -pwm teb swaging tshuab siv los ntawm Manners Technology maj mam forges kawg ntawm stainless hlau raj mus rau hauv ib rab koob nrog ib tug tshwj xeeb taper thiab ob - qhov qauv los ntawm reciprocating radial txav ntawm cov pwm. Piv nrog rau cov tsoos machining drilling, swaging yog txheej txheem txias txias uas tso cai rau cov hlau fibers ntws tsis tu ncua raws li cov duab, tsis yog tsuas yog ua kom qhov ntom thiab lub zog ntawm cov khoom, tab sis kuj zam cov burrs thiab micro- tawg uas yuav raug tsim thaum lub sij hawm machining. Los ntawm kev tswj cov forging zaus, pub tus nqi, thiab pwm profile, cov lus qhia zoo ib yam nrog cov qhov hauv lub qhov thiab cov phab ntsa tuab tuab tuaj yeem tsim tau.
Txhawm rau txuas lub siab -precision hexagonal puag nrog lub spun-forged rab koob, yuav tsum muaj cov txheej txheem vuam uas tuaj yeem ua kom muaj zog yam tsis muaj kev puas tsuaj rau cov khoom siv. Laser welding qhia tau hais tias muaj txiaj ntsig zoo hauv qhov no. Lub teeb laser yog tsom mus rau qhov chaw me me (txog li 0.1mm nplai), nrog rau lub zog loj heev. Nws tuaj yeem tam sim ntawd (hauv milliseconds) yaj cov hlau hauv zos thiab tsim lub pas dej molten. Piv nrog rau cov arc vuam tsoos, laser welding muaj cov cua kub tsawg heev thiab ib qho chaw nqaim heev. Qhov no txhais tau hais tias cov cua sov me me tau hloov mus rau hauv lub hauv paus thiab lub koob lub taub hau thaum lub sij hawm vuam, tiv thaiv cov teeb meem xws li kev loj hlob, deformation lossis corrosion txo (sensitization) ntawm stainless hlau vim overheating. Weld seam tsim los ntawm laser welding muaj qhov tob loj - mus rau - dav piv, siab zog, thiab zoo li du, thiab yuav luag tsis muaj kev sib tsoo tom ntej, tswj kev ncaj ncees thiab zoo nkauj ntawm cov khoom.
Tom qab welding, lub koob lub cev nkag mus rau saum npoo tiav. Electro- polishing (Electropolishing) yog qhov kov tiav. Lub workpiece yog muab tso rau hauv lub anode nyob rau hauv ib tug tshwj xeeb electrolyte tov thiab ces electrified. Tom qab ntawd, tam sim no qhov ntom ntom ntawm microscopic protrusions ntawm qhov chaw yog siab dua, thiab cov hlau tawg tau nrawm dua, ua tiav cov nyhuv theem. Electro- polishing ua raws li tus qauv ASTM B912 tuaj yeem tshem tawm kwv yees li 2-3 micrometers ntawm cov khoom siv saum npoo av, tshem tawm tag nrho cov microscopic khawb, burrs, thiab embedded impurities sab laug los ntawm tig los yog spinning forging. Qhov tshwm sim yog daim iav-zoo li lub ntsej muag du nrog lub zog qis heev. Qhov no tsis yog tsuas yog txhim kho corrosion kuj, tab sis qhov tseem ceeb tshaj, lub ultra- du nto txo ​​cov kua residue, uas txhais tau hais tias kev tu kom huv si ntau dua thiab txo cov kev pheej hmoo ntawm kev sib kis rau kev lag luam khoom noj uas yuav tsum tau hloov cov ntaub ntawv txhaj tshuaj.
Hauv qab no ze ze yog tshuaj passivation (Passivation). Lub workpiece yog immersed nyob rau hauv nitric acid los yog citric acid kua, qhov twg los ntawm cov tshuaj tiv thaiv, cov dawb hlau hais tawm nyob rau saum npoo vim mechanical processing yog yaj, tso cai rau ntau ntawm cov chromium - nplua nuj alloy nto yuav raug. Nyob rau hauv cov huab cua, chromium sai sai ua ke nrog oxygen los ua ib tug nyias tab sis tsis tshua muaj ntom thiab ruaj khov chromium oxide passivation zaj duab xis. Cov yeeb yaj kiab no yog qhov tseem ceeb ntawm kev tiv thaiv corrosion ntawm 304 stainless hlau. Tom qab kev kho mob tsis zoo, V3 koob txhaj tshuaj tuaj yeem ua kom ci thiab tshiab txawm tias raug cov kua qaub, ntsev, lossis ntau yam khoom noj ntxiv rau lub sijhawm ntev, tsis muaj xeb.
Thaum kawg, tom qab multi- qhov chaw ultrasonic tu kom tshem tawm tag nrho cov khoom seem ntawm kev ua thiab kev kho tshuaj, txhua rab koob yuav tsum tau ua haujlwm zoo xws li kev tshuaj ntsuam xyuas iav, kev tshuaj xyuas qhov loj me, thiab ntsuas huab cua nruj ua ntej muab tso rau hauv plua plav- pov thawj thiab noo noo{2}} pov thawj ntim. Tag nrho cov txheej txheem tsim khoom, los ntawm CNC code programming mus rau qhov kawg kev soj ntsuam zoo, yog nyob rau hauv lub moj khaum ntawm ISO 13485 kev kho mob cov cuab yeej zoo tswj system, xyuas kom meej lub controllability ntawm cov txheej txheem thiab traceability ntawm cov txiaj ntsig. Nws yog qhov tseeb ntawm kev sib cuam tshuam, nrhiav- ntawm- cov txheej txheem zoo tshaj plaws uas sib koom ua ke tsim kom muaj kev ruaj khov thiab txhim khu kev qha kev ua tau zoo ntawm V3 koob txhaj tshuaj nyob rau hauv qhov xav tau kev lag luam ib puag ncig.
