Jakisoni (woumba) pulasitiki (kapena woumba jakisoni) ndi njira yomwe pulasitiki imasungunuka koyamba mu silini yotenthetsera yamakina a jakisoni, kenako ndikuthamangitsidwa ndi cholumikizira kapena cholumikizira cha nkhungu chotseka. . Sikuti zimangopanga zinthu zambiri, zinthu zapamwamba kwambiri pazinthu zambiri, komanso zimakhala ndi mapulaneti osiyanasiyana komanso ntchito zosiyanasiyana. Chifukwa chake, kuwumba jakisoni ndi chimodzi mwazinthu zofunika zokumbira mu pulasitiki.
Ntchito Zoyambira Makina a Sukisoni Wopanga jakisoni
Kuumba jakisoni kumatheka ndi makina jakisoni.
Ntchito zoyambira zamakina a jakisoni ndi:
1. Kutenthetsa pulasitikiyo m'malo otsuka;
2. Ikani kukakamizidwa kwambiri kuti musungunuke kuti muchotse ndikudzaza khola.
Zolinga / zida za jakisoni
Kuumba jakisoni wa thermoplastics nthawi zambiri kumachitika ndi matenda ndi kudzaza. Zipangizo zomwe zimagwiritsidwa ntchito pophatikiza ndi kuzizira zimapangidwa ndi makina owumba jakisoni, jakisoni Wozimba ndi zida zogulitsa (monga kuwuma kwakuthupi).
Chipangizo cha jakisoni
Chida cha jekeseni chimazindikira kwambiri chisonyezo ndikugwirizanitsa mu makina a jakisoni. Jakisoni ndi kukakamizidwa, kusunga ndi ntchito zina. Chipangizo cha jekeseni cha screwn chimagwiritsidwa ntchito kwambiri, ndipo chimapangidwa ndikugwirizanitsa cholakwika ndi jakisoni mu screw.
Mwakutero, iyenera kutchulidwa kuti ndi chipangizo chophatikizika. Mukamagwira ntchito, pulasitiki mu hopper imagwera mu silinda yotentha ndi kulemera kwake. Pamene screw imazungulira, pulasitiki imasunthira kutsogolo. Pakadali pano, zomwe zimayendetsedwa ndi chithumira chakumanja chakumanja, ndipo mkatimonso amafanso. Kutentha komwe kumapangidwa ndi kudula kumakweranso ndipo matenthedwe amakwera mkhalidwe wosungunula.
Ndi kusungidwa kwa zinthu kumapeto kwa silinda yotentha, mphamvu yamphamvu (kukakamizidwa) kwazinthu izi kumakankhira scress kumbuyo, ndipo kusintha kwa malire kumagwiritsidwa ntchito kuchepetsa malire. Mukamachotsa pamalo ena, mawuwo amasiya kuzungulira, potero kudziwa (kuyeza) kuchuluka kwa jekeseni kamodzi.
Pambuyo pa zomwe nkhuyu imakhazikika, pomwe mankhwalawo akangotulutsidwa, nkhungu imatsekedwa kachiwiri ndipo njira ya jekeseni imayambitsidwa. Pakadali pano, scarilic cylinder (jakisoni wa jakisoni) wa chipangizo cha jakisoni chikugwiritsa ntchito mphamvu, ndipo pansi pa kukakamizidwa kwambiri, ndipo kumapeto kwake kumayamba ndodo yake .
Chipangizo cha jekeseni chimapangidwa ndi chovala, mbiya, mphuno komanso chida choyendetsa. Chotupa cha jakisoni nthawi zambiri chimagawika magawo atatu: kudyetsa, kukakamiza, kuphatikizika, kuchuluka kwa 2 ~ 3, ndi gawo la 16 ~ 18.
Mukasungunuka ndikuchotsedwa pamwambo, gawo la kusungunuka lidzabwerera kumbuyo kudzera mu screw poyambira chifukwa cha mphamvu yoyeserera yomwe imachitika. Popewa izi, valavu yoyang'ana imalumikizidwa kumapeto kwa screw. Kwa chlorinyl molyvinyl chloride, mutu wolumikizira wokhazikika umagwiritsidwa ntchito.
Mbiya ndi gawo la cholembera ndipo chimapangidwa ndi kutentha. Zopangidwa ndi zitsulo zopsinjika kwambiri. Mndandanda wa mizere yamagetsi yothira magetsi amaikidwa pampando wa mbiya kuti kutentha kwa mbiya. Kutentha kumayendetsedwa ndi thermocourourous kuti apatse pulasitiki yoyenera.
Mfuzi ndi kusintha pakati pa mbiya ndi nkhungu, yomwe imayenerera ndi chinsinsi chopatulikitsa chifukwa ndi gawo lofunikira la pulasitiki kusungunuka mwachindunji. Mwambiri, kubuka jakisoni umagwiritsa ntchito zotseguka zotseguka. Pa zotsika zotsika ma polyamines, valavu ya singano imagwiritsidwa ntchito.
Kusintha kwa chipwirikiro chagalimoto kumatha kuchitika ndi galimoto yamagetsi kapena mota hydraulic, ndipo mayendedwe obwezeretsanso amakwaniritsidwa pogwiritsa ntchito kupanikizika kwa Hydraulic.
Magawo a makina a jakisoni amadziwika ndi chipangizo cha jakisoni: kuchuluka kwa jakisoni kumatanthauza kuchuluka kwa makina owumbidwa mu nkhungu nthawi iliyonse, chomwe chingafotokozedwe ndi kuchuluka kwa polystyrene kusungunuka, kapena ndi voliyumu wa jekeseni wosweka;
Kukakamizidwa kwa jakisoni kumanena za zovuta zomwe zimayikidwa pamtanda wa mbiya nthawi ya jakisoni; Kuthamanga kwa jakisoni kumatanthauza kuthamanga kwa screw panthawi ya jakisoni.
Chida chopanga
Kuphatikiza pa kumaliza kutsegulidwa ndi kutseka kwa nkhungu
Kaya ndimakina owombera ndi makina kapena hydraulic kapena hydraulic makina, kutseguka kwa nkhungu ndikutseka kuyenera kusintha, nthawi yopuma, yosanja.
Kuchokera pamalingaliro aukadaulo, nkhungu zotseguka ndi zotsekera ziyenera kukhala ndi zotsatirapo zake. Kuthamanga kwa template kuyenera kukhala pang'onopang'ono ndikuyenda pang'onopang'ono pozungulira nkhungu, ndikuchepetsa ndikuyenda pang'onopang'ono mukamatsegula nkhungu. Pofuna kupewa kuwonongeka kwa nkhungu ndi magawo.
Mphamvu yomwe imagwiritsidwa ntchito ku nkhungu pakupanga nkhungu kuti musunge nkhungu imatchedwa mawola, ndipo kufunikira kwake kuyenera kukhala kwakukulu kuposa kupanikizika kwa gawo ndi malo owombera). Kupanikizika kwapakatikati kumakhala pakati pa 20 ndi 45 MPA.
Popeza mzere wamphamvu umawonetsa kukula kwa makina oumba jakisoni, mphamvu yayikulu yokulunga jakisoni imagwiritsidwa ntchito posonyeza ma makina a jakisoni, koma palinso ubale wapakatiwo pakati pa kuwongolera mphamvu ndi kuchuluka kwa jekeseni.
Komabe, choyimira champhamvu champhamvu sichikuwonetsa mwachindunji cha mankhwala omwe afesedwa, ndipo sizoyenera kugwiritsa ntchito. Opanga ambiri padziko lapansi amagwiritsa ntchito mphamvu yotsatsira / kuchuluka kwa jakisoni kuti awonetsetse makonzedwe a jakisoni, chifukwa voliyo ya jakisoni, yamakina osiyanasiyana. Pali njira yofananira yofananira, volida yama jakisoni ya jakisoni imabwerezedwa mobwerezabwereza 100mpa, ndiye kuti, kuchuluka kwa jakisoni = voretical voliyumu yozungulira: Kuthamanga kwa jakisoni:
Kachitidwe
Njira ya Hydralic ya jakisoni wa makina a jakisoni imagawika mu dongosolo lowongolera la hydraulic la hydraulic, dongosolo lowongolera la servo ndi njira yolamulira molingana.
Chifukwa cha zovuta za hydraulic dongosolo, zofananira zonunkhira bwino zimatengedwa ngati chitsanzo chosonyeza autilaini. Makhalidwe a dongosolo lino ndi: pali kuwongoleredwa ndi kuwopa zinthu zomwe zimachitika mu Dera la magetsi (mawonekedwe a electromagnetic pogawa Valve, valve mogwirizana kwambiri).
Kufalikira kwamphamvu kwa mphamvu zoperekedwa ndi mphamvu ya mphamvu yamagetsi imagwiritsidwa ntchito poyendetsa bwino kwambiri poyambira liwiro, liwiro lolowera, liwiro lotseguka ndi kuthamanga kwa jakisoni. Kukakamizidwa. Screw Torque. Mutu wa jakisoni umaponya mphamvu. Kupanikizika kotentha kwamphamvu ndi kamodzi, siteji kapena yopanda pake.
