Xa iinjineli zichaza a intsimbi yokuphosa inxalenye, abayaleli nje ukumila-bazibophelele ekuzinzeni kwe-dimensional phantsi kwe-300 bar, ukunyaniseka kwe-microstructure emva kokuhamba ngebhayisikile eshushu, kunye nokugqiba umphezulu ochasene ne-galling kwi-abrasive hydraulic flow. Siye sabona iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype ngenxa yokuba ukunyamezela ukuphosa kwakungalungelelanisi kunye nezibonelelo zokugqibela zomatshini-okanye okubi ngakumbi, ngenxa yokuba ukuqinisekiswa kwezinto eziphathekayo akuzange kuhambelane nemeko yokuphathwa kobushushu efunekayo ukuxhathisa ukukhathala.
Kutheni “uKuphoswa nje” Akwanelanga kwiMishini yezicelo eziBalulekileyo
Ukuphosa iindawo zentsimbi kwiivalvu zehydraulic, izindlu zempompo zepiston, okanye i-winch center shafts zifuna ngaphezulu kwesakhono sesiseko. Ifuna ukuqonda ukuba i-solidification shrinkage idibana njani nokususwa kwesitokhwe se-CNC, indlela i-cobalt-nickel alloys esabela ngayo kutyalo-mali ngokuchasene nokuphosa isanti, kwaye kutheni i-AMS 5387 cobalt alloy 6 iziphatha ngokwahlukileyo kwimilomo yodonga olubhityileyo ngokuchasene neeplagi zecandelo elishinyeneyo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha ukuphosa nganye njengesiganeko se-metallurgical-kungekhona ukudluliselwa kwejometri. Oko kuthetha ukuqinisekiswa kolwakhiwo lweenkozo ngokusebenzisa i-macroetch kubo bonke ubushushu, ukuqinisekisa isithuba phakathi kwe-interdendritic ngaphambi kokuba kuqale ukusebenza, kunye nokwenza imaphu yoxinzelelo olushiyekileyo kwiiflange zezindlu zesilinda kusetyenziswa uluhlu lwe-strain-gauge.
Siye sabukela abathengi betshintsha ababoneleli emva kokufumanisa ubulukhuni obungahambelaniyo kwi-T800 cobalt-based castings-kuphela ukufumana unobangela oyintloko yayingeyiyo isiseko, kodwa ukufudumeza okungalawulekiyo ngexesha le-welding yezinto ezenziwe ngoomatshini. Inkqubo yethu edibeneyo isusa eso sikhewu: ukuphosa, unyango lobushushu, kunye nokugqitywa kwe-multi-axis kwenzeka phantsi kophahla olunye, kunye nokulandelwa okupheleleyo ukusuka kwisatifikethi se-billet eluhlaza ukuya kwingxelo yokugqibela ye-CMM. Akukho handoffs. Akukho kwahlulwa kwebhetshi. Imbali nje enye elawulwayo yobushushu kunye neyomatshini kwicandelo ngalinye.
Iindidi ezine zokuCasa—Ngalunye Lwenzelwe Ukusebenza, Hayi Imo
Ayizizo zonke ii-castings ezisebenzela injongo enye. Ipotfoliyo yethu ibonisa iindlela zokungaphumeleli zehlabathi lokwenyani- kunye nendlela yokuzikhusela:
- Ukuphoswa kwentsimbi: Isetyenziselwa iziseko zempompo apho ivibration idambise ibaluleke ngaphezu kokuqina kwe-tensile-ngoko sikhulisa ukubala kwamaqhuqhuva egraphite kunye nepearlite/ferrite ratio, hayi nje ubulukhuni beBrinell
- Iintsimbi zentsimbi kunye neentsimbi ezingenasici: Kwimizimba yevalve yoxinzelelo evezwe kwi-chloride-rich oilfield fluids-siqinisekisa i-pitting resistance resistance (PREN) amaxabiso nge-ASTM A959, kungekhona nje iingxelo zekhemistri.
- Amacandelo e-cobalt-nickel alloy: Kubandakanya i-AMS 5387 i-cobalt alloy 6 iipompo zepompo, apho ukuhanjiswa kwe-carbide kuyalela ubomi bokugqoka-senza imephu ye-SEM-EDS kumacandelo anqamlezayo, hayi nje i-microscope ebonakalayo
- Ukwenziwa kwe-alloy ye-T800 engekho semgangathweni: Apho ijiyometri iphikisana neendlela eziqhelekileyo zesixhobo-sidibanisa utyalo-mali kunye ne-5-axis mill-turn ukubamba ± 0.015 mm GD&T kwi-coaxial bores kunye ne-radial runout phantsi kwe-0.02 mm
Oku akuyothiyori. Enye iOEM yaseYurophu yaphinda yayila kwakhona indlu yempompo yempompo engaselunxwemeni emva kokungaphumeleli kwamabala amathathu. Umthengisi wabo wokuqala ubambe unyamezelo oluqinileyo-kodwa baphose imfuno yezithuba zengalo zedendrite yesibini. Siyiphucule kwakhona inkqubo yokungena, songeza ulawulo lokuqinisa umkhombandlela, kwaye sahambisa iicastings nge-SDAS eqinisekisiweyo ≤ 45 µm. Ubomi basentsimini bandile ukusuka kwiinyanga ezisi-8 ukuya ngaphezulu kwezingama-26.
Apho uninzi lwaBaboneleli baSika iikona-Kwaye Sivale Njani uMsantsa
Abanye abavelisi baphatha iiodolo zenxalenye yentsimbi njengentengiselwano. Bamkela imizobo, ukucaphula ixesha lokukhokela, kunye nenqanawa. Siqala ngaphambili-kunye neqela lakho lobunjineli.
Ngexesha lokuqinisekiswa komzobo, senza iflegi imingcipheko engahoywanga kakhulu: ukuguquguquka kokuqina kodonga olumema ukukrazula okushushu kwi-cobalt alloys; idrafti yee-engile zingekho nzulu kakhulu ekususweni kweqokobhe leceramic kulwakhiwo lotyalo-mali; okanye i-GD&T callouts ezingqubana noburhabaxa obunokufezekiseka bomphezulu (Ra > 6.3 µm kwisanti, iRa > 3.2 µm kutyalo-mali). Asithi nje "kunzima ukwenza." Sicebisa ezinye iindlela-ezifana nokufudusa isici sedatum kwindawo engoomatshini, okanye ukucacisa ukubanda kwendawo ukulawula ukucutheka kumphathi obalulekileyo.
Sikwavavanya into ecingwa ngabanye: izatifikethi zezinto ezingenayo ziqinisekiswa ngokuchasene nohlalutyo lokwenene lobushushu nge-OES spectroscopy. Yonke iqashiso lenziwa uvavanyo lwe-ultrasonic lwe-porosity engaphantsi komhlaba ngaphambi kokuba kuqale ukusebenza. Kwaye ukuhlolwa kokugqibela kubandakanya uvavanyo olusebenzayo-imizimba ye-valve yoxinzelelo kwi-1.5 × uxinzelelo lokusebenza, emva koko ukhangele ukuvuza kwi-0.05 cc / min threshold.
Ukukhetha iqabane elilungileyo kuthetha ukubuza imibuzo echanekileyo
Ngaphambi kokuba ugqibezele umthengisi wenxalenye elandelayo yentsimbi, buza:
- Ngaba ungandibonisa iingxelo ezintathu zokugqibela zeCMM zejometri efanayo-kwaye uqaqambise indlela oye walungisa ngayo iimpawu zokunyamezelana phakathi kwamaqashiso?
- Loluphi uhambo lwakho olude oluqhubekayo lwe-AMS 5387 ngaphandle kokukhatywa? Yayiyintoni unobangela wokungaphumeleli kokuqala—kwaye wayilungisa njani?
- Ngaba ulawula zombini ukuphosa kunye noomatshini bokugqibela? Ukuba akunjalo, ngubani oqinisekisa ujongano phakathi kwe-as-cast kunye ne-machined datums?
- Ukusingatha njani ukulandeleka kumacandelo abalulekileyo? Ngaba iqashiso-kwinqanaba-okanye inqanaba lobushushu, kunye neelog zembali ezigcweleyo zobushushu?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iimpendulo ewe kuzo zone. Asihambisani nje neecastings. Sihambisa ukuzithemba-kukuphindwa kwe-dimensional, ukungaguquguquki kwezinto, kunye nokuthembeka komsebenzi. Kuba kwiinkqubo zehydraulic, izithuthi zobunjineli, kunye neoyile kunye nezixhobo zegesi, akukho mda "wokuvala ngokwaneleyo."
Ukuba olandelayo intsimbi yokuphosa inxalenye kufuneka enze phantsi koxinzelelo, ukunxiba, kunye noxinzelelo lwe-thermal-qala nge-metallurgy, kungekhona ukuthengisa. Qala ngolawulo lwenkqubo eqinisekisiweyo, hayi amaphepha esithembiso. Qala apho ukuchaneka kuqala khona: kubumba, ukunyibilika, kunye nomlinganiselo.
