Raws li lub hauv paus tseem ceeb ntawm kev tswj cov kua dej, kev ua haujlwm ntawm hydraulic solenoid li qub cuam tshuam ncaj qha rau kev ntseeg tau thiab kev ua haujlwm ntawm cov khoom siv. Cov txheej txheem molding yog qhov tseem ceeb hauv kev txiav txim siab solenoid valve zoo, nrog rau kev siv dav hauv kev xaiv cov khoom siv, kev tsim qauv, thiab kev tsim khoom siv tshuab. Kab lus no yuav piav qhia txog cov ntsiab lus tseem ceeb ntawm hydraulic solenoid valve molding txheej txheem los ntawm kev xav ntawm pwm tsim, cov khoom molding, thiab tom qab- ua.
I. Pwm Tsim thiab tsim khoom
Hydraulic solenoid li qub feem ntau yog molded siv precision txhaj molding los yog tuag-casting. Cov pwm qhov raug ncaj qha cuam tshuam qhov kev ruaj ntseg ntawm lub cev valve. Pwm tsim tsom rau ntawm qhov sib npaug ntawm qhov sib npaug thiab cov txheej txheem txias txias: lub ntsiab channel txoj kab uas hla yuav tsum sib phim cov yas yaj lub flowability, thiab ceg raws yuav tsum muaj qhov sib npaug -section kom txo qhov poob siab. Cov kav dej txias yuav tsum muab sib npaug sib npaug ntawm cov kab noj hniav, kom ntseeg tau tias qhov kub thiab txias sib txawv hauv ± 2℃los tiv thaiv cov tub ntxhais ntawm lub valve vim qhov tsis sib xws. Rau cov hlau valve lub cev ua haujlwm nyob rau hauv siab - siab, tuag- casting pwm yuav tsum tau ua los ntawm H13 kub- ua haujlwm tuag steel thiab nitrided kom nce qhov tawv tawv (Ntau dua lossis sib npaug rau HV900) kom tiv taus cov khoom hnyav dua.
II. Cov txheej txheem molding
1. Yas Valve Lub Cev Moulding
Engineering yas xws li PA66+GF30 (muaj 30% iav fiber ntau) feem ntau xaiv rau lawv cov roj tsis kam thiab lub zog. Kev txhaj tshuaj molding tsis tas yuav tsum muaj kev tswj xyuas nruj: qhov kub ntawm qhov kub ntawm 260-280 degree, txhaj tshuaj siab 80-120 MPa, thiab tuav lub sij hawm kho raws li phab ntsa thickness (feem ntau 1-3 vib nas this / hli). Txhawm rau tshem tawm cov kev ntxhov siab sab hauv, annealing ntawm 80℃yog xav tau tom qab demolding, ua raws li 2-teev tuav kom ruaj khov qhov ntev.
2. Hlau Valve Lub Cev Moulding
Rau siab - kev siv siab, aluminium alloy (xws li ADC12) lossis tooj dag tuag- feem ntau siv casting. Tuag- casting txheej txheem tsis yog: alloy kub 650-700 degree, pwm kub 180-220 degree, thiab boost siab 50-80 MPa. Qhov tseem ceeb sealing nto tau ua tiav tom qab CNC tiav kom ntseeg tau tias flatness Tsawg dua lossis sib npaug li 0.01 hli. Lub tshuab nqus tsev impregnation yog siv los sau cov microporous tsis xws luag, ua kom lub siab ntsuas siab tshaj 35 MPa.
III. Electromagnetic Assembly Integration Txheej txheem
Lub tshuab electromagnetic yog qhov txhab siv lub tshuab tsis siv neeg winding. Enameled hlau nrog ib txoj kab uas hla ntawm 0.3-0.5mm yog densely raug mob nyob rau hauv ntau txheej, nrog polyimide zaj duab xis rwb thaiv tsev ntawm cov txheej. Cov khoom siv tseem ceeb yog DT4 hluav taws xob ntshiab hlau, annealed kom txo cov coercivity (tsawg dua los yog sib npaug li 80A / m), thiab txuas nrog lub valve qia ntawm nyiaj-raws li brazing kom paub meej lub sij hawm teb tsawg dua 10ms. Lub coil thiab valve lub cev yog encapsulated nrog epoxy resin, nrog ib tug rwb thaiv tsev tsis kam ntawm ntau tshaj los yog sib npaug rau 100MΩ tom qab kho.
IV. Ncej -Kev Ua Haujlwm thiab Kev Tswj Xyuas Zoo
Lub tshuab moulded solenoid valve tau dhau los ua peb lub tshuab ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov tseem ceeb (xws li lub rooj zaum ntawm lub rooj zaum aperture ntawm ± 0.005mm) thiab dhau qhov kev ntsuas airtightness (helium leak test precision ntawm 1 × 10⁻⁹ Pa·m³ / s). Rau lub cev valve lub cev, qhov siab - ntsuas kub ntawm -40℃mus rau 120℃kuj tau ua los xyuas kom meej cov khoom nkag mus.
Xaus
Cov txheej txheem molding rau hydraulic solenoid li qub sawv cev rau kev sib tshuam ntawm cov ntaub ntawv science, precision manufacturing, thiab kua dynamics. Los ntawm optimizing pwm tsim, precisely tswj molding tsis, thiab txhim kho ncej- cov txheej txheem, cov khoom sib xws thiab durability tuaj yeem txhim kho tau zoo. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm additive manufacturing thiab composite cov ntaub ntawv technology, solenoid valve molding yuav ntxiv evolve rau lightweighting thiab ntse manufacturing.
