Pamene mainjiniya amatchula a mchenga kuponyera utumiki fakitale pazigawo zachitsulo zofunika kwambiri, sikuti amangoyitanitsa ma castings-akuteteza kukhazikika kwa 300-bar hydraulic load, microstructure integrity pambuyo pa chithandizo cha kutentha, ndi zero kulolerana kwa porosity mu cobalt alloy nozzles. Ndicho chenicheni chomwe timachiwona tsiku ndi tsiku ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-malo omwe kuponya mchenga si njira yobwerera mmbuyo koma njira yolondola yopangira zigawo zomwe zimalephera ngati zipatuka ndi 0.05 mm.
Kuponya Mchenga Komwe Kumakwaniritsa Zofuna Pantchito-Osati Mapangidwe Okha
Ogula ambiri amaganiza kuti kuponya mchenga kumatanthauza ntchito yotsika mtengo, yotsika kwambiri. Koma m'zinyumba zopopera zopopera kwambiri kapena zodzigudubuza zam'mphepete mwa nyanja, kuponyera mchenga nthawi zambiri ndiko njira * yokhayo * yotheka yopita ku geometry yooneka ngati ukonde CNC isanamalize—makamaka pamene makulidwe a khoma adutsa 120 mm kapena zibowo zamkati zimafuna ma cores opanda zolembera. Tawona makasitomala akusintha kuchoka pakupanga ndalama kupita kuponya mchenga pambuyo pakusweka kunachitika panthawi ya chithandizo cha kutentha kwa AMS 5387: kuzizira pang'onopang'ono kwa nkhungu za mchenga wobiriwira kunachepetsa kupsinjika kwa kutentha ndi 40% mu midadada ya T800-based cylinder blocks.
Malo athu ogwirizana ndi ISO amagwiritsa ntchito mchenga wa silica womangika ndi mankhwala okhala ndi chinyezi chowongolera komanso zomangira - osati "mchenga wamba". N’chifukwa chiyani zili zofunika? Chifukwa kusakanikirana kosagwirizana kumabweretsa kusintha kwa nkhungu. Ndipo kusintha kwa nkhungu kumawononga ma callout a GD&T pamapampu a piston. Timatsimikizira nkhungu iliyonse ndi makina owunikira tisanathire, kenaka timatsata makulidwe apakati pogwiritsa ntchito mfundo zoyezera-osati zowona.
Chilangochi chikufotokozera chifukwa chake ma valve athu okakamiza amakhala ndi ma ASME B16.34 Class 600 popanda kukonzanso zowotcherera - komanso chifukwa chomwe ma OEM agalimoto amabwereranso ku ma winch am'badwo wachiwiri okhala ndi zolimba zothamanga kuposa momwe adayambira koyamba.
Kumene Kuponyera Mchenga ndi CNC Machining Zimaphatikizana
Opereka ena amawona kuponya ndi kukonza ngati madipatimenti osiyana. Timawatenga ngati unyolo umodzi wopitilira. Mukatitumizira chojambula cha pulagi ya cobalt-nickel alloy, gulu lathu limawunikiranso kapangidwe ka mageti *ndikuganizira kakulidwe kanu*. Timayika zokwera kuti makhazikitsidwe omaliza a CNC apewe kudula kosokonekera m'malo ocheperako. Timayika zida pamalopo * asanakhale * mpumulo womaliza wa kupsinjika - kuti kupotoza sikulepheretsa lipoti lanu la CMM.
Kuphatikiza uku kumafunika kwambiri pazigawo monga maziko a pampu: zitsulo zolemera kwambiri zomwe zimafuna mphero ya 3-axis pankhope zisanu ndi chimodzi, kuphatikizapo kubowola kwakuya kwa ma bolts. Ngati kutsika kwa kuponyedwa kupitilira 0.8 mm / m2, kukonza makina kumadya ndalama zolipirira masheya - komanso kuopsa kowonetsa porosity yapansi panthaka. Chifukwa chake timawongolera nthawi ya shakeout, kuziziritsa mofanana m'maenje otsekeredwa, ndikutsimikizira kutsika pamagawo atatu: monga-cast, pambuyo pochepetsa kupsinjika, ndi kukonza kale.
Zotsatira zake? 92% yopereka chiphaso choyamba pamadongosolo apakati-palibe malupu obwereza, palibe zodabwitsa zopatuka pakuwunika komaliza.
Kufufuza Kwazinthu Zomwe Mungatsimikizire-Osati Kungonena
"Zinthu zotsimikizika" sizitanthauza pang'ono pokhapokha mutazitsata ku nambala ya kutentha, chipika chosungunula, ndi lipoti la test bar. Timatulutsa ma aloyi onse a cobalt (kuphatikiza AMS 5387 ndi T800 giredi) kuchokera ku mphero zomwe zili ndi certification ya EN 10204 3.1-ndikusunga zolemba zonse pagawo lililonse: kusanthula kwamankhwala, kukula kwambewu pa ASTM E112, ndi ma Charpy amakhudzidwa ndi -40 ° C pazofunsira zakunja.
Sitimangodinda "SS316" pa tag. Timayika manambala a kutentha pamtundu uliwonse, timawalozera panjira yathu ya ERP motsutsana ndi zolemba zomwe zikubwera, ndikuphatikizanso zolemba zonse zopezeka ndi zolemba zotumizidwa. Makasitomala m'modzi wa zida zamafuta aku North America adagwiritsa ntchito izi kuchotsa kafukufuku wa API Q1 pasanathe mphindi 45 - palibe zopempha zotsatila.
Ndipo makasitomala akafunsa kuti, "Kodi mungatengenso gulu la chaka chatha?" - timakoka chipika cha ng'anjo chomwechi, mchenga wosakanikirana womwewo, zomangira zomwezo. Osati "zofanana." Zofanana.
Chifukwa chiyani Mainjiniya Apadziko Lonse Amasankha Fakitale Yopangira Mchenga Iyi
Simufunikanso wogulitsa wina yemwe amalemba mawu mwachangu ndikubweretsa mochedwa. Mukufunika mnzanu amene amalengeza kusamvana kwa GD&T *kusadayambe* kugwiritsa ntchito—monga kufotokoza kuti kulolerana kwa ±0.02 mm pa bore ya 200-mm-diameter kumafuna makina achiwiri, osati kungoponya. Muyenera kumveka bwino pa oyendetsa nthawi yotsogolera: kukonzekera kwa nkhungu yamchenga kumatenga masiku 7; kusinthidwa kwa chitsanzo kumawonjezera 3; Kuchiza kwa AMS 5387 kumawonjezera 10-osati "masabata a 2-4" popanda kuwonongeka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapereka chidziwitso chimenecho. Oyang'anira ma projekiti athu amalankhula uinjiniya bwino-osati mawu ogulira zinthu. Adzakuuzani chifukwa chomwe mphuno ya aloyi ya cobalt imafunikira zosunga zobwezeretsera zipolopolo za ceramic, kapena chifukwa chake zitsulo zosapanga dzimbiri zopitilira 80 kg zimafunikira chithandizo chapakati kuti chimveke bwino. Palibe malonjezo osadziwika bwino. Fiziki yokha, zitsulo, ndi zolembedwa zolembedwa.
Ngati dongosolo lanu lotsatira la kuponya mchenga liyenera kuchitika—osati kungofika—yambani ndi kuunikanso mwaukadaulo, osati pepala lamtengo. Kusiyana kumawonekera m'moyo wakumunda, osati pamapepala.
