Xa kufunwa izixhobo zoomatshini bokwakha umzi-mveliso amaqabane onikezelo lwe-OEM, iinjineli kunye nabaphathi bokuthengwa kwempahla bajongana nomda omxinwa ngempazamo. Indlu yevalve enye ene-0.02 mm dimensional drift inokubangela ukungaphumeleli kwenkqubo ye-hydraulic phantsi koxinzelelo lwe-350-bar. I-winch centre shaft roller eyenziwe kwi-cobalt alloy ye-T800 engahambelani inokudinwa emva kwemijikelo ye-12,000-hayi i-50,000 echaziweyo. Siye sabona ii-OEM ezintathu zaseMntla Melika zilibazisa ukuqaliswa kwemveliso ngenxa yokuba ukuphosa kwe-porosity akuzange kubonwe de kube kuvavanyo lokugqibela lokusebenza. Ayingomcimbi womgangatho-yinkqubo yokubonakala komsantsa.
Ukuchaneka kwehlabathi lokwenyani kuqala ngaphambi kokusikwa kokuqala
Ukuthembeka okwenene kumacandelo oomatshini bokwakha akwakhiwanga ekuhlolweni-kufakwe ngexesha lokukhethwa kwezinto kunye nokuqina kwimbali yokushisa. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke inxalenye yempompo ye-cobalt ye-cobalt ye-AMS 5387 iqala ngokulandelelwa kwe-billet eqinisekisiweyo: inombolo yobushushu, ingxelo yohlalutyo lokunyibilika, kunye neerekhodi zophicotho lomthengisi ezifakwe phambi kokuba izinto ezikrwada zicinywe isango lokugcina impahla. Akukho ngaphandle. Siye savavanya ababoneleli be-cobalt-nickel be-17 kwiminyaka eyi-8-kuphela i-4 edibana ne-microstructure consistency threshold yethu yokusabalalisa ubungakanani beenkozo kunye ne-carbide dispersion. Elo nyathelo lokucoca lilodwa liphelisa i-63% yokuqhekeka okunokubakho kwinkonzo kwimibhobho enxibe kakhulu.
Indawo yabo ethobela i-ISO iqhuba ukuphosa okufanayo kunye nokuhamba komsebenzi ngomatshini-hayi ulandelelwano lwezandla. Isiseko sempompo yentsimbi esantiweyo siphantsi koxinzelelo lonyango oludambisa ubushushu *phambi kokusekwa* kwe-CNC, hayi emva koko. Ngoba? Ngenxa yokuba ukusabalalisa kwakhona uxinzelelo olushiyekileyo ngexesha lomatshini kubangela i-0.05-0.12 mm warpage kwizindlu ezinodonga oluncinci. Amaziko abo omatshini ohamba nge-axis amahlanu abambe ±0.005 mm unyamezelo lwendawo kwi-120-mm-diameter-diameter cylinder bores-eqinisekisiweyo phakathi kwenkqubo kunye ne-Renishaw PH10M probes, kungekhona nje kwitshekhi yokugqibela ye-CMM. Yileyo ndlela iindibano zempompo yepiston zifezekiswa ngayo <1.2 µm Umphezulu we-Ra kwimihlaba yokutywina ebalulekileyo ngaphandle kokutsalwa okwesibini.
Kutheni "idityanisiweyo" ingeyiyo intengiso ye-fluff-yi-inshurensi ye-dimensional
Ezinye iifektri zikhuphela ngaphandle, ezinye zigqibezela ikhontrakthi engaphantsi. I-QINGDAO QIANGSENYUAN ingumnini wekhonkco elipheleleyo: ukufakwa kotyalo-mali kwiiplagi zengxubevange ye-cobalt, ukugalelwa kwesanti kwiifreyimu zentsimbi yesakhiwo, i-CNC ye-multi-axis yemizimba yevalvu yoxinzelelo, kunye nokulawulwa kobushushu bomoya kwi-T800 rollers shaft. Olu lawulo oluthe nkqo luzisa iingenelo ezintathu ezinokulinganiswa:
- Ukunyaniseka kweMicrostructure: Iiparamitha zokunyanga ubushushu zilungelelaniswe kwindawo echanekileyo yokuphosa-hayi iigophe eziqhelekileyo. Ukuhluka kobunzima kwi-400-mm-ubude be-winch shaft kuhlala ngaphakathi kwe-± 2 HRC, kungekhona ± 8 HRC.
- Uzinzo lweDimensional: Ireferensi yokulungiswa kwereferensi yomgangatho wedatha-hayi amanqaku e-CAD. Isiphumo: I-92% yokupasa kuqala ukuthotyelwa kwe-GD&T kwiindibano zempompo ezinzima ezine-14+ ii-callouts eziyinyaniso.
- Ulungelelwaniso lomsebenzi womphezulu: Ubunzulu be-shot peening buhlengahlengiswa ngokuvezwa komphezulu-ubuso obutywiniweyo bufumana iiprofayili zoxinzelelo olulungiselelwe ukuxhathisa ukudinwa; iijenali ezithweleyo zifumana iiprofayili ezilungiselelwe ukugcinwa kweoyile.
Sakhe saphonononga imizobo yesiseko sempompo yokomba ekude nonxweme apho i-GD&T stack-ups yenze i-0.18 mm yomngcipheko wokunyamezelana. Iqela labo lobunjineli liye layichaza kwiiyure ze-48-kungekhona "ingenakwenzeka," kodwa ngesicwangciso esihlaziyiweyo sedatha kunye nolandelelwano lwendawo lomatshini olunciphisa umngcipheko nge-76%. Ayikokubonisana oko. Kubunjineli ngokubambisana.
Apho uninzi lweefektri zisilela khona—kwaye indlela ukuchaneka okusitshintsha ngayo izibalo
Abanye abathengi bacinga ukuba zonke ii-castings ziyalingana ukuba zidibana ne-ASTM A494 okanye i-EN 1559. Ayilunganga. Imilomo ye-cobalt alloy ifuna ukuqiniswa kwe-directional ukuphepha ukuncipha kwe-centerline. Iintsimbi zokuxhoma i-excavator boom mounts zifuna ukuhanjiswa kwegraphite ye-nodular kuqinisekiswe ngokuhlalutya umfanekiso-kungekhona nje iingxelo zamandla okuqina. Umgca wokujula wesanti we-QINGDAO QIANGSENYUAN usebenzisa isampulu ye-metallographic yexesha lokwenyani: yonke i-5th yokugalela ihluzwa ngokukhawuleza, ifakwe, kwaye ifotwe. Iimephu zesakhiwo sokutya okuziinkozo zibuyela kwi-algorithms yobushushu beziko phakathi kwemizuzu engama-90.
Yiyo loo nto ii-T800 zabo ezingekho mgangathweni zinikezela ukuxhathisa ukunxiba okuphindaphindiweyo-nangona abathengi betshintsha ijometri phakathi kokubaleka. Omnye umxhasi we-Asia-mpuma ye-Asia wayila ngokutsha indlu ye-hydraulic motor motor kabini ngexesha lokulinganisa. Uhlaziyo ngalunye luthunyelwe ngeentsuku ze-11, kunye ne-hardness gradients (42-48 HRC) kunye namaqhezu evolumu ye-carbide (18.3-18.7%) kuzo zonke iiloti ezintathu. Akukho mfanelo ifunekayo.
Ukuthembeka onokukuqinisekisa-kungekhona nje ukuthembisa
Yonke into ethunyelwayo ibandakanya ngaphezulu kwesatifikethi sokuthotyelwa. Ithwala:
- Ukulandelwa kwezinto ezigcweleyo ukuya kwinani lobushushu beladle kunye nohlalutyo lwe-spectrographic
- Iingxelo zokuhlola ze-CMM ezinexabiso elithelekiswa nelona xabiso liqhelekileyo kuzo zonke iimpawu ze-GD&T
- Ukuqinisekiswa komphezulu ongaphezulu ngokufundwa kweprofilometer ephathekayo-hayi nje "Ra < 0.8 µm” amabango
- Idatha yovavanyo olusebenzayo apho kufanelekileyo: amazinga okubola koxinzelelo lweevalvu, itorque-ukungaphumeleli kwiindibano zeplagi
Oku akukho ngaphezulu. Ngumahluko phakathi kokubamba impazamo ye-0.03 mm bore taper ngaphambi kokuhlanganisana-okanye ukuyifumana ngexesha lenkonzo yasentsimini kwi-1,200 yexabiso leyure yokuphumla. Inkqubo yabo yokucwangcisa i-lean ilandelela i-WIP ngomyalelo, kungekhona i-batch, ngoko ke ukuveliswa kwevolumu ephakathi kugcina iifestile zokuhanjiswa kweentsuku ezi-±-3-nokuba nomxholo we-geometry we-70%.
Kuba OEMs ukwakha iinkqubo hydraulic, izithuthi zobunjineli, okanye iimpompo oilfield, i izixhobo zoomatshini bokwakha umzi-mveliso ukhetho alukho malunga nesicatshulwa esisezantsi. Kumalunga nokuba ngubani obambe i-metallurgical, ijometri, kunye nemisonto esebenzayo iqinile ngokwaneleyo ukuba imveliso yakho yokugqibela yenze-umjikelezo emva komjikelo, ixesha emva kwexesha. I-QINGDAO QIANGSENYUAN TECHNOLOGY ayinikezeli nje iinxalenye. Babonelela ngokuqikelelwa.
