Sechinhu chakakosha chemagetsi ekudzora masisitimu, kuita kwehydraulic solenoid mavharuvhu kunokanganisa zvakananga kuvimbika uye kugona kwemidziyo. Maitiro ekuumba chinhu chakakosha pakuona solenoid valve mhando, inosanganisira yakazara mashandisirwo ekusarudza zvinhu, dhizaini yekugadzira, uye tekinoroji yekugadzira. Ichi chinyorwa chichatsanangura zvine hungwaru mapoinzi akakosha eiyo hydraulic solenoid valve molding process kubva pamaonero ekugadzira mold, material molding, uye post{2}}processing.
I. Mold Design uye Manufacturing
Mavharuvhu eHydraulic solenoid anowanzo kuumbwa achishandisa majekiseni chaiwo kana kufa-kukanda. Kurongeka kweiyo mold kunokanganisa zvakananga kugadzikana kwedimensional yemuviri wevharuvhu. Magadzirirwo eMould anotarisisa kuyerera kwechaneru chiyero uye kutonhodza sisitimu marongero: dhayamita huru yechiteshi inofanira kuenderana nekuyerera kwepurasitiki yekunyunguduka, uye machanera emapazi anofanirwa kuve nechikamu chedenderedzwa-chikamu kuti kuderedze kurasika. Nzira dzemvura inotonhorera dzinofanirwa kugovaniswa zvakaenzana kutenderedza mold, kuve nechokwadi chekusiyana kwekushisa mukati me ± 2 dhigirii kudzivirira musimboti wevharuvhu kunamatira nekuda kwekusaenzana shrinkage. Pamavharuvhu esimbi anoshanda pasi pepamusoro-mamiriro epressure, anofa-molds yekukanda inofanirwa kugadzirwa neH13 inopisa{10}}working die die steel and nitrided kuti iwedzere kuomarara kwepasi (Kupfuura kana kuenzana neHV900) kuti isamirire mitoro inodzokororwa.
II. Material Molding Process
1. Plastic Valve Body Molding
Mapurasitiki einjiniya akaita sePA66+GF30 (ane 30% yegirazi faibha) anowanzo kusarudzwa nekuda kwekuramba kwemafuta uye simba. Majekiseni ekuumba maparamendi anoda kudzora kwakasimba: tembiricha yebhari yakaiswa pa260-280 dhigirii, jekiseni kudzvanywa 80-120 MPa, uye kubata nguva inogadziriswa zvinoenderana nemadziro ukobvu (kazhinji 1-3 masekonzi/mm). Kuti ubvise kushushikana kwemukati, annealing pa80℃inodiwa mushure mekudhirowa, ichiteverwa neawa 2-kubata kudzikamisa zviyero.
2. Metal Valve Body Molding
Pakushandisa{{0}pressure applications, aruminiyamu alloy (seADC12) kana brass die-kukanda kunowanzo shandiswa. Die{{4}maparamendi ekukandira ndeaya: alloy tembiricha 650-700℃, mold tembiricha 180-220℃, uye boost pressure 50-80 MPa. Nzvimbo dzakakosha dzekuisa chisimbiso dzinotevera kupedzisa CNC kuti ive nechokwadi chekudzika Pazasi kana kuenzana ne0.01 mm. Vacuum impregnation inoshandiswa kuzadza microporous defects, kuwedzera chiyero chekumanikidza kusvika pamusoro pe35 MPa.
III. Electromagnetic Assembly Integration process
Iyo electromagnetic coil inokuvadzwa uchishandisa otomatiki mamhepo muchina. Waya ine enameled ine dhayamita ye0.3-0.5mm ine ronda rakasimba muzvikamu zvakawanda, ine polyimide film insulation pakati pema layer. Iyo yakakosha zvinhu ndeye DT4 yemagetsi yakachena simbi, yakanyungudutswa kuderedza kumanikidza (Zvishoma pane kana kuenzana ne80A/m), uye yakabatana nevharuvhu hunde kuburikidza nesilver-based brazing kuti ive nechokwadi chekupindura isingasviki 10ms. Iyo coil nevharuvhu muviri wakavharirwa ne epoxy resin, ine inodzivirira yekudzivirira yeKukura kupfuura kana kuenzana ne100MΩ mushure mekurapa.
IV. Post-Kugadzirisa uye Kudzora Hunhu
The molded solenoid valve inopinda katatu-dimensional coordinate measuring machine kuti iongorore makuriro akakosha (sevharuvhu aperture aperture tolerance ye ± 0.005mm) uye opfuura bvunzo yekusapinda mhepo (helium leak test yechokwadi ye1×10⁻⁹ Pa·m³/s). Pamiviri yemavharuvhu epurasitiki, bvunzo dzepamusoro-kutenderera kutenderera kubva -40 dhigirii kusvika 120 dhigirii inoitwa zvakare kuratidza kusamira kwechinhu.
Mhedziso
Iyo yekuumba maitiro e hydraulic solenoid mavharuvhu inomiririra mharadzano yesainzi yemidziyo, kunyatsogadzira kugadzira, uye fluid simba. Nekukwenenzvera kugadzira mold, kunyatso kudzora maparamita ekuumba, uye kunatsiridza magadzirirwo-magadzirirwo, kuenderana kwechigadzirwa uye kusimba kunogona kuvandudzwa zvakanyanya. Mune ramangwana, nekufambira mberi kwekuwedzera kwekugadzira uye composite zvinhu tekinoroji, solenoid valve molding inoenderera mberi ichishanduka ichienda kune kureruka uye nehungwaru kugadzira.
