zinthu

1. Chimango chachikulu:
Thupi la makina a hydraulic a mtundu wa chimango ndi kapangidwe ka chimango chogwirizana, chopangidwa ndi zigawo zomangira zolumikizidwa ndi chitsulo, ndi mawindo am'mbali pakati pa zipilala zakumanzere ndi kumanja, pogwiritsa ntchito kapangidwe kabwino ka Q355B kolumikizira mbale zachitsulo, kulumikiza mpweya wa carbon dioxide; pambuyo polumikiza, imafunika kudutsa mu Annealing treatment imachotsa kwathunthu kusintha kwa kulumikiza ndi kupsinjika, kuonetsetsa kuti zigawo zolumikizidwazo ndizolimba komanso zosasinthika, ndipo kulondola kumasungidwa. Mtanda wotsika, zipilala, ndi m'mwamba zimamangiriridwa kale ndi tie rods (hydraulic pre-tightening) kuti apange chimango chophatikizana; pali block yotsetsereka pakati pa fuselage, ndipo block yotsetsereka imatsogozedwa ndi njanji yotsogolera yamakona anayi ndi octagonal, ndipo mbale yotsogolera ya block yotsetsereka imapangidwa ndi zinthu zophatikizika za A3+CuPb10Sn10 , Njira yotsogolera pa chipilala imagwiritsa ntchito njanji yotsogolera yochotseka.

①Mtanda wapamwamba ndi pansi:Mtanda wapamwamba ndi pansi umalumikizidwa ndi mbale yachitsulo ya Q355B, ndipo kupsinjika kwamkati kumachotsedwa pambuyo polumikiza kuti zitsimikizire kukhazikika kwa kapangidwe ndi kulondola kwa zida zokha. Bowo lalikulu loyika silinda limapangidwa pamtengo wapamwamba. Silinda ya hydraulic cushion ndi hydraulic cushion zimayikidwa mkati mwa mtanda pansi.

② Chipilala: Chipilalacho chimalumikizidwa ndi mbale yachitsulo ya Q355B, pambuyo polumikiza, chithandizo chochepetsa kupsinjika chimachitika. Chipilala chowongolera chosinthika chimayikidwa pa chipilalacho.

③Ndodo yomangira ndi loko: Zipangizo za ndodo yomangira ndi loko ndi chitsulo cha 45#. Ndodo yomangira imafanana ndi ulusi wa loko wachikazi ndipo imamangidwa kale ndi chipangizo chomangira champhamvu kwambiri kuti chitseke thupi.

2. Chotsitsa:
Chotsekeracho ndi chopangidwa ndi mbale yachitsulo cholumikizidwa ngati bokosi, ndipo gulu la pansi la chotsekeracho ndi chidutswa chonse cha mbale yachitsulo kuti zitsimikizire kulimba ndi mphamvu zokwanira. Chotsekera cha chosindikizira cha hydraulic cha mtundu wa chimango cha thupi la galimoto chimagwiritsa ntchito njanji zowongolera zamakona anayi ndi mbali zisanu ndi zitatu. Pali magulu anayi a zowongolera pazipilala zakumanzere ndi kumanja. Mapepala owongolera a chotsekeracho amasuntha molunjika pa njanji zowongolera, ndipo kulondola kwa mayendedwe kumadalira njanji zowongolera zowongolera. Chitsulo chopendekera chimagwiritsidwa ntchito kusintha kuti chitsimikizire kufanana ndi tebulo logwirira ntchito, kusintha kosavuta, kulondola kwakukulu, kusunga kulondola bwino pambuyo pa kusintha, komanso mphamvu yamphamvu yotsutsana ndi eccentric. Mbali imodzi ya awiriawiri a njanji yowongolera imapangidwa ndi zinthu za alloy, ndipo mbali inayo imapangidwa ndi zinthu za alloy zochokera ku mkuwa. Kuphatikiza apo, njanji yowongolera yazimitsidwa, yokhala ndi kuuma pamwamba pa HRC55, kukana bwino kusweka komanso moyo wautali wautumiki. Pamwamba pa njanji yotsetsereka pali dzenje lopaka mafuta kuti mafuta azilowetsedwe kuti azitha kudzola ziwalo zosuntha. Kusintha kwabwino kwa chotsetsereka kumachitika poyang'anira valavu yoyendera yofanana, yomwe imagwiritsidwa ntchito posintha bwino ndi kutseka nkhungu panthawi yoyesa nkhungu, ndipo imatha kusinthidwa mkati mwa 0.5-2mm/s.

3. Benchi logwirira ntchito losamutsira:
Chosindikizira cha hydraulic chopangidwa ngati chimango chopangira zophimba za chipolopolo cha galimoto chili ndi tebulo logwirira ntchito losunthira patsogolo. Tebulo logwirira ntchito losuntha ndi kapangidwe ka welding ya mbale yachitsulo ya Q355B. Pambuyo pa welding, chithandizo chochepetsa kupsinjika chimachitika. Tebulo logwirira ntchito losuntha limakonzedwa ndi mipata ya "T" ndi mabowo a ejector. Miyeso ya groove ya "T" ndi dzenje la ejector pin zimapangidwa motsatira chithunzi cha kapangidwe chomwe chaperekedwa ndi Party A. Siyani 400mm pakati pa groove ya "T" popanda kugaya. Chokhala ndi ndodo yolumikizirana ndi chivundikiro cha fumbi, kuuma kwa ejector treatment ndodo kuli pamwamba pa madigiri a HRC42. Kulondola kobwerezabwereza kwa tebulo logwirira ntchito loyenda ndi ±0.05mm, ndipo njira yoyendetsera imayendetsedwa ndi chochepetsera liwiro, ndipo ndi kapangidwe kodziyendetsa yokha. Ndi chipangizo cholumikizira, pamene kusiyana pakati pa ndege yapansi ya tebulo logwirira ntchito losuntha ndi ndege yapansi ya beam yapansi kuli kokulirapo kuposa 0.3mm, wolandila saloledwa kugwira ntchito. Perekani zophimba zonse za mabowo a mandrel. Pali malo olumikizirana pakati pa tebulo logwirira ntchito, kukula kwake ndi 14mm m'lifupi mpaka 6mm kuya.

4. Silinda yayikulu:
Silinda yayikulu yamafuta imagwiritsa ntchito kapangidwe ka masilinda ambiri komwe kamaphatikiza silinda ya pistoni ndi silinda ya plunger. Ndodo ya pistoni imagwiritsa ntchito zitsulo za kaboni zapamwamba kwambiri, ndipo pamwamba pake zimazimitsidwa kuti ziwonjezere kuuma; thupi la silinda limagwiritsa ntchito zitsulo za kaboni zapamwamba kwambiri kuti zitsimikizire kufanana kwa zinthu. Silinda yamafuta imatsekedwa ndi mphete yotsekera yapamwamba kwambiri yochokera kunja.

5. Silinda ya pilo ya hydraulic:
Chipangizo chosungiramo ma hydraulic cushion chimayikidwa mkati mwa mtanda wapansi wa hydraulic press yofanana ndi chimango kuti chipange chimango cha chivundikiro cha chipolopolo cha galimoto. Hydraulic cushion ili ndi ntchito ziwiri: hydraulic cushion kapena ejector, yomwe ingagwiritsidwe ntchito kupereka mphamvu yopanda kanthu yogwirira ntchito panthawi yotambasula mbale yachitsulo kapena kutulutsa. Chogulitsacho, hydraulic cushion ili ndi kapangidwe ka korona kamodzi, ndipo ili ndi sensa yosunthira yolunjika. Makina osindikizira amatha kuzindikira mosavuta malo a digito osinthira sitiroko a slider ndi hydraulic cushion, ndipo ntchitoyi ndi yosavuta komanso yothandiza.

6. Sunthani tebulo logwirira ntchito kuti mukweze silinda yolumikizira:
Ma silinda anayi okweza ndi omangirira a makina osindikizira a hydraulic amtundu wa chimango opangira chivundikiro cha chipolopolo cha galimoto ndi mapangidwe a piston. Amayikidwa pa mtanda wopingasa wapansi. Tebulo losunthika likhoza kukwezedwa likakwezedwa, ndipo tebulo losunthika likhoza kumangidwa likatsitsidwa. Pamwamba pa mtanda wocheperako.

7. Silinda ya buffer:
Chipangizo choboola chogwirira ntchito chimakonzedwa momwe zimafunikira, chomwe chimapangidwa ndi silinda ya buffer, dongosolo la buffer ndi makina olumikizidwa, ndipo chimayikidwa pamwamba pa mtanda wapansi wa chosindikizira kuti chichepetse m'mphepete, kuboola ndi njira zina zoboola. Silinda ya buffer ndi dongosolo la buffer zimatha kuyamwa kugwedezeka ndikuchotsa kugwedezeka panthawi yoboola.
