Xa iinjineli zichaza a rollformers inxalenye umzi-mveliso, abakhangeli nje ukugoba kwesinyithi-bafuna ukuqinisekiswa kwe-dimensional phantsi komthwalo, ukunyaniseka kwe-microstructural emva kokuhamba ngebhayisikile yobushushu, kunye nokunyamezela kwe-zero kwi-drift kwi-high-pressure hydraulic manifolds. Yiyo loo nto ukuchaneka ingeloxesha lokuthengisa apha-yimfuno esisiseko ebhakwe kuyo yonke i-cobalt alloy nozzle, yonke indlu yepiston pump cylinder, kunye ne-winch centre shaft roller esiye sayenza kule minyaka ili-12 idlulileyo.
Kutheni i-"Rollformers Part Factory" iligama elilahlekisayo lokukhangela-kwaye yintoni kanye oyidingayo
Uninzi lwabathengi bachwetheza "i-rollformers part factory" belindele ukubunjwa okubandayo kwekhoyili. Kodwa ekusebenzeni, i-83% yamacandelo afuna ukungqinelana kwe-roller-grade yokwenyani-i-GD&T eqinile, ubukhulu bodonga obuphinda-phindayo, utshintsho olungenamthungo phakathi kweendawo ezenziweyo kunye noomatshini-azenziwe kwii-rollingers kwaphela. Ziveliswa ngeenkqubo ezixubeneyo: utyalo-mali oluntsonkothileyo kubume obunetha, emva koko umatshini we-CNC we-multi-axis ukubamba ± 0.005 mm kwindawo yokutywina ebalulekileyo. Siye sabona oku xa i-OEM yaseMntla Melika impompo isuka kwimizimba yevalve enesitampu kunye ne-welded ukuya kumatshini we-AMS 5387 wezindlu-kwaye wasika ukusilela kwintsimi ngama-67%.
Ingxaki yokwenyani ayizozixhobo. Lulawulo lwesinyithi. I-cobalt-nickel alloys efana ne-T800 ayiphenduli kwiindlela eziqhelekileyo okanye izicwangciso zokupholisa. Izinga lokuqina komsebenzi wabo linyuka emva kwe-0.3 mm yobunzulu bokusika. Umyinge wesondlo ogwetywe gwenxa uqhekeza umaleko ongaphantsi komhlaba. Ukucima okulibazisekayo kuphazamisa isakhiwo sengqolowa. Yiyo loo nto uphendlo lwe "rollformers part factory" luhlala lukhokelela kwisiphelo esifileyo: uninzi lweevenkile ezithengisayo azinaludibaniso lonyango lobushushu, ukulandeleka kweCMM, okanye inkqubo yokuqinisekiswa kwealloyi efunekayo kwiindawo ezibalulekileyo zobuthunywa.
Izakhono ezine ezahlula amahlakani esinyithi echanekileyo ukusuka kubaboneleli ngokubanzi
Silandele ngaphezulu kwe-210 yovavanyo lwababoneleli kuwo wonke amacandelo e-hydraulic, ioyile kunye negesi, kunye namacandelo ezithuthi ezinzima. Abadlali abaphezulu bahlala bebonisa ezi zinto zine zingaxoxiswana:
- Umnombo wezinto eziphathekayo kunye nokulandeleka kwinqanaba lebhetshi-hayi nje iicerts zokugaya, kodwa imephu yobushushu obugcweleyo ukusuka kwingot eluhlaza ukuya kwinxalenye egqityiweyo, eqinisekisiwe ngokuchasene ne-ASTM A992 kunye ne-AMS 2269
- Inkqubo-itshixiwe iiparamitha zomatshini kwizantya zokuphotha ezibhalwe kwi-superalloys, izixhobo zejometri, kunye noxinzelelo lokupholisa oluqinisekisiweyo ngokwebakala lezinto eziphathekayo (umzekelo, i-T800 ifuna i-42% ephantsi ye-RPM kune-Inconel 718 kwi-DOC elinganayo)
- Ukuqhubela phambili komda phakathi kokuphosa-ku-machining handoffs-akukho kulungisa kwakhona izinto ezothusayo. Sisebenzisa iimodeli zokuphosa ezenziwe ngelaser ukuze sibuyekeze kwangaphambili ukushwabana ngaphambi kokusikwa kokuqala
- Ukuhlola okusebenzayo-kungekhona nje ukudlula / ukusilela ukulinganisa-Izindlu zovavanyo loxinzelelo lwe-1.5 × ukusebenza, ukuqinisekiswa kokugqiba umphezulu ngeprofilometry kumhlaba wokutywina, kunye nemephu ye-microhardness kuzo zonke iindawo ezichatshazelwe bubushushu.
Oku akuyothiyori. Xa i-Southeast Asian offshore rig operator efuna imilomo yokutshintshwa kwiimpompo ze-injection subsea, umthengisi wabo wangaphambili wahambisa iiyunithi ezili-12-i-3 ayiphumelelanga uvavanyo lokuqhuma kwi-1,200 psi. Iqela lethu liye laphonononga umzobo walo wokupakishwa kwe-GD&T, laqaphela utshintsho olungalawulwayo lwedatha phakathi kwemigca yokubumba kunye nomatshini wokugqibela wokubhoboza, laza layila ngokutsha ujongano olulungisiweyo. Zonke iiyunithi ezilandelayo ze-24 zaphumelela ukuqinisekiswa kwe-psi eyi-1,800.
Iindleko ezifihlakeleyo zokuVelisa "Okulungileyo okwaneleyo".
Abanye abaxumi bayabuza: "Ngaba unokuthelekisa ixabiso lomthengisi wethu wangoku?" Sihlala siphendula ngedatha yokwenyani. Kwisiseko sempompo yensimbi efuna ukunyamezela kwe-ISO 2768-mK kunye ne-Zn-Ni plating: ibhidi yexabiso eliphantsi yayiyi-$ 89 / iyunithi. Isicatshulwa sethu: $ 132. Ngoba? Ngenxa yokuba inkqubo yabo isebenzise ukugaywa kwesanti yodwa-okukhokelela kwi-11% ye-scrap evela kwi-porosity kwi-lugs ephezulu yoxinzelelo. Izethu zisebenzisa i-centrifugal-assisted sand casting + stress-relieving + post-machining ultrasonic inspection. I-scrap yehle ukuya kwi-0.7%. Iindleko zolondolozo lwexesha lonke zehle nge-40% ngenxa yokususwa kwe-bolt-hole ekuhlanganiseni ibala.
Loo mahluko we-$43 uhlawula emva kweenyanga ezi-3.2. Umngcipheko wokwenene awuyiyo indleko-yi-cascade esezantsi: i-0.012 mm ngaphandle kwe-roundness kwi-winch center shaft roller ibangela ukuthwala ukuhluka kwangaphambili, ukukhawuleza ukuphuka kwe-cage. Silinganise oku kumboniso wokungcangcazela kwiinqwelo ezintathu zeemoto zobunjineli. Ukulungiswa kwakungeyonto ingqongqo-yayilawula ukuphosa umkhombandlela wokuqina ngaphambi kokuba nayiphi na intsimbi ibethe i-lathe.
Yintoni elandelayo kwi-High-alloy Precision Manufacturing
Ukujonga phambili, umda olandelayo awungoomatshini abakhawulezayo-zizandla ezikrelekrele eziphathekayo. Ngoku sifaka iithegi zembali eshushu kwi-T800 castings: indawo nganye iphethe igophe layo lokupholisa ngqo, lisivumela ukuba siqikelele indlela yokuziphatha exhomekeke kwi-microstructure ngaphambi kokuba isixhobo sokuqala sibandakanyeke. Oku kuhambisa umgangatho ukusuka ekubhaqweni ukuya kuyilo. Kubathengi abakhangela "i-rolling part factory", impendulo iyavela: ukuchaneka kwesinyithi ukubumba ngoku kuthetha ukuphosa ubukrelekrele, ukuqeqeshwa komatshini, kunye noxanduva lokuphendula nge-metallurgical-hayi nje iikhoyili eziqengqelekayo.
Ukuba isicelo sakho sifuna ukuphinda-phinda apho ukusilela kungeyondlela yokukhetha, qala ngokulandeleka kwezinto, qinisekisa ukutolika kwe-GD&T-hayi nje umzobo-kwaye unyanzelise kwiingxelo zovavanyo olusebenzayo, hayi nje uluhlu lokuhlola. Yiloo ndlela osuka ngayo kwiindawo zokukhangela ukuya ekuqinisekiseni ukusebenza.
