Kufotokozera zaukadaulo wa ng’anjo ya tungsten-molybdenum yapakatikati ya sintering

1. SCR intermediate frequency power supply: Mbali zake zazikulu ziyenera kukwaniritsa zofunikira izi:

Dongosolo loyang’anira ndi digito, palibe kuwongolera

Dongosolo lowongolera limagwiritsa ntchito ISP programmable logic array template integrated control.

1.2 Kusanthula kwapadera koyambira ndi 100% kupambana koyambira

Kudalirika kwakukulu ndi kukhazikika kwakukulu

1.4 mphamvu zotulutsa mphamvu nthawi zonse, zimatsimikizira mphamvu yayikulu

1.5 chitetezo changwiro komanso chodalirika

Dongosolo lowongolera lidzaperekedwa ndi njira zosiyanasiyana zodzitetezera monga kuchulukirachulukira, kuchulukitsa kwapakati pafupipafupi, kutayika kwa gawo, kuperewera kwa bolodi lowongolera, kutsika kwamadzi ozizira, komanso kutentha kwamadzi ozizira kwambiri, komanso ma alarm omwe amamveka ndi kuwala amaperekedwa.

Kudzizindikiritsa kotsatizana kotsogola

Dongosolo lowongolera lili ndi gawo lodzizindikiritsa la magawo, ndipo magetsi omwe akubwera magawo atatu amatha kulumikizidwa mosasamala.

1.7 Kutentha kotseka mawonekedwe owongolera:

Mphamvu yamagetsi imaperekedwa ndi mawonekedwe owongolera kutentha kwakunja, kuphatikiza ndi PLC yakunja, thermometer ya infrared kapena thermocouple ndi chida chowongolera kutentha kwa PID, chomwe chimatha kuzindikira bwino kutentha ndi mphamvu yotseka-loop control system, kuti kutentha kutentha kwa workpiece ndi basi kusinthidwa kwa zida zoikamo. Mtengo wowerengeredwa.

1.8 yodalirika komanso yotetezeka yonse yoyika mawonekedwe a silicon

1.9 gwiritsani ntchito nduna ya GGD

GGD-mtundu mpanda ndi osakaniza ozizira anapanga unit nduna, onse a conductive kukhudzana pamalo a mkati pafupipafupi magetsi olumikizidwa kwa malata owala yokutidwa mkuwa utali wonse wa 10-15 μ m.

1. 10 Ntchito iliyonse yozindikira kutentha kwa madzi imayima yokha ikalephera.

1. 11 Iwo ali kunja shutdown mawonekedwe ndipo amasiya pamene mawonekedwe chatsekedwa.

2. Sensor koyilo

2.1 Kuti muchepetse tanki yamakono ndikuchepetsa kutayika kwa inductor, coil induction idapangidwa kuti ikulitsidwe.

2.2 Injini yotulutsa ndi ziwiri zokha.

2.3 Kholo la koyilo limatsekeredwa ndi botolo ladothi pakati pa ndime yachitsulo chosapanga dzimbiri ndi koyilo.

2.4 Pamwamba pa koyiloyo amapoperapo ndi utomoni woyabwa kuti aletse kuyika kwa fumbi lachitsulo ndikuwonjezera mphamvu yotchinjiriza.

2.6 Pambuyo popiringa mayeso a hydrostatic 0.6MPa / 30min, kuwonetsetsa kuti koyilo yamadzi.

3. Dongosolo lowongolera ndi kabati yogwira ntchito

Opaleshoni gulu makamaka ntchito magetsi ndi kulamulira ng’anjo sintering, kutentha kulamulira kujambula.

3.1 Kabati ya opareshoni imatengera mawonekedwe osunthika, ndipo kabati yogwirira ntchito ndi njira yakutsogolo komanso yakumbuyo kwa chitseko. Kumangirira kabowo kakang’ono, kotero kuti zingwe za infuraredi, thermocouple ndi ma siginecha mumayendedwe okhudzana ndi magetsi amatsogolera.

3.2 Kabati ili ndi block terminal (kuphatikiza spare terminal), switch ya air, switching power supply ndi zina. Magetsi owongolera osinthira ndi ± 12VDC, omwe amagwiritsidwa ntchito popereka mphamvu ku thermometer ya infrared. Ndipo pali soketi yamagetsi ya magawo awiri kuti ogwira ntchito yosamalira agwire ntchito.

3.3 Mesa ili ndi matebulo anayi apakatikati owonetsa ma frequency apakati, voteji ya DC, DC yapano komanso mphamvu yapakatikati.

3.4 Kuyeza kwa kutentha kumayesedwa ndikuyendetsedwa ndi thermocouple ndi infrared:

3.4.1. Infrared mita:

Chojambulira cha infrared chimayikidwa pamagulu atatu osinthika osinthika, gawo lopangira ma siginecha limayikidwa pafupi ndi chivundikiro cha ng’anjo, ndipo gawo lazizindikiro ndi cholumikizira cholumikizira zimalumikizidwa ndi chingwe chotetezedwa.

3.5. Chojambuliracho chimatenga chojambulira chaposachedwa kwambiri chojambulira opanda mapepala. 3.6. Sinthani ndi chizindikiro: Kusinthana ndi chizindikiro pa chiwonetsero cha console ndikuchita zolakwika motsatana, zodziwikiratu / pamanja

Mphamvu, thermocouple / infrared, switch switch, sing’anga yoyambira ndi kuyimitsa pafupipafupi, kusintha mphamvu ndi ntchito zina.

Chida chowongolera kutentha kwa 3.7 PID: Makinawa amasankha mitundu iwiri ya zida zowongolera kutentha kwa PID zomwe zili ndi ntchito yomweyo. Ndi mtundu wa FP21 wa SHIMADEN CO., LTD. Mmodzi wa iwo ntchito thermocouple kutentha kulamulira, ndi winayo. Amagwiritsidwa ntchito powongolera kutentha kwa infrared.

4 , ng’anjo yotentha thupi

Ng’anjo yamoto: zigawo ziwiri mkati ndi kunja, wosanjikiza wakunja ndi welded ndi 10mm wandiweyani 16Mn kuwotcherera zakuthupi. 8mm wandiweyani wosanjikiza wamkati ndi welded 1Cr18Ni9Ti, kuchuluka kulimbikitsa mipiringidzo, kupewa mochulukira madzi kuthamanga ng’anjo liner opunduka zigawo zamkati ndi zakunja, pakati ndi pansi.Internally welded ndi pindani pedals: anakonza mu zigawo ziwiri za misalignment , amene angagwiritsidwe ntchito ndi antchito potsegula. ndi kutsitsa. Chifukwa cha squat yapamwamba, ma pedals amakonzedwa m’magulu awiri, okhala ndi mapazi atatu pamtunda uliwonse ndi pansi kuti ogwira ntchito atenge pamwamba. Zomwe zimagwiritsidwa ntchito, ndipo gawo lapansi limagwiritsidwa ntchito ndi wogwira ntchito kuti atenge gawo lapansi. Mukamaliza kugwiritsa ntchito, pindani phazi la phazi kuti lisatenthedwe ndi sensa.

5, ntchito benchi:

Gantry ntchito pamwamba kutalika kuchokera pansi 1. 8 M, kuchokera kutalika kwa ng’anjo kutsegula 0.6M, 2.9M wonse kutalika. Kunja kuli mpanda, pakati seti Buti, Buti worktop pamwamba ndi matread plate ndi opangidwa osaterera. Bokosi lowongolera la haidrojeni ndi nayitrogeni limakonzedwa kumbali ya makwerero, ndipo mita yothamanga ya rotor ndi valavu yosinthira gasi imakonzedwa mkati kuti isinthe gasi ndikuwongolera kuthamanga. Gantryyo imapangidwa kuti iwonongeke ndikulekanitsidwa mozungulira ng’anjo ya ng’anjo, ndipo thupi la ng’anjo limayikidwa. Mukayika, tsekani choyimira ndikumangitsani ndi mabawuti.

6, kutentha thupi

Chotenthetsera cha tungsten crucible chimagwiritsidwa ntchito kutenthetsa chitsulo cha tungsten potenthetsera induction, kenako zinthu zomwe ziyenera kutenthedwa zimatenthedwa.

Zida izi zili ndi tungsten crucible kukula kwa φ 560 × 1200. Makulidwe a khoma:

7 , zipangizo refractory

Zinthu zokanira pakati pa inductor ndi tungsten crucible zimakhala ndi aluminium oxide ndi zirconium oxide.
