Iyo ba injeniyeri bagaragaje silicon mold casting uruganda serivisi kubintu byubunyangamugayo buhanitse, ntabwo zitumiza ibice gusa-birinda umutekano muke munsi ya 300 MPa hydraulic imizigo, microstructure ikomeza nyuma yo kuvura ubushyuhe, hamwe nubusugire bwubutaka bukomeza kubaho nabi muri pompe zamavuta. Uku nukuri kubikorwa byihishe inyuma yumunsi - ntabwo kwihanganira theoretique ku gishushanyo, ahubwo ni imikorere igaragara muri serivisi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora kimwe mubikoresho bike byabyara umusaruro mubushinwa aho silicon ibumba (uburyo bwihariye bwo gushora imari hifashishijwe ibishishwa bya ceramic bishingiye kuri silika) ikoreshwa muburyo bukoreshwa mubutaka bwa cobalt-nikel nka AMS 5387 na T800. Twashyizeho imibiri irenga 12,000 yumuriro wa hydraulic yo kugenzura amazi yo mu nyanja kuva 2021-buri kimwe gisaba ± 0,05 mm zingana na bore yibanze, zero imbere muri zeru kuri ASTM E192, hamwe nubushakashatsi bwuzuye kuva kumyanda mvaruganda kugeza kuri raporo ya CMM yanyuma. Urwo rwego rwo guhuzagurika ntirubaho kubwamahirwe. Bibaho mugihe casting idatandukanijwe no gutunganya, kuvura ubushyuhe, cyangwa kwemeza GD&T - kandi mugihe buri cyiciro gitangiranye nibikoresho byemewe, ntabwo byiringiro byabatanga.
Ibyemezo bitatu bya tekiniki bitandukanya silicon ikora ikora hamwe na casting yemewe - kandi ibi bisobanura ibyo abakiriya bapima mubyukuri mubigeragezo:
- Igikonoshwa cyo kugenzura: Bisanzwe silika sol binders isatura hejuru ya 1,100 ° C mugihe cobalt alloy isuka. QINGDAO QIANGSENYUAN ikoresha silika yahinduwe ya siloidal + ya sisitemu ya silika igizwe na 1,280 ° C - igenzurwa hifashishijwe isesengura rya gravimetricique kuri buri giceri. Ibi bikuraho microfissures nyuma igaragara nkubusa butangiza umunaniro wububiko bwa pompe ya silinderi.
- Gucunga neza icyerekezo. X-ray tomografiya yemeza ko ingano yerekana ingano ihuye ningingo zihangayikishije-ingenzi kubice AMS 5387 ikora kuri 450 ° C.
- Gufunga ibahasha yanyuma. Ikipe yacu yubaka mm 0.3-0.5 mm mububiko bukomeye bwo gufunga, hanyuma igenzura kugoreka nyuma yimashini hamwe na laser tracker ihuza ibice byashizwemo. Abakiriya bavuga ko 40% ari bike-ingingo ya mbere yanze kuri winch center shaft rollers kubera iyi.
Bamwe bashobora kuvuga ko imashini ya CNC yonyine itanga ukuri neza kuruta gukina. Ariko ibyo birabura ibya fiziki: gutunganya kg 120 ya T800 ivanze mumashanyarazi ya kg 22 isesagura 82% yikiguzi cyibikoresho - kandi bizana imihangayiko isigaye ibangamira ubuzima bwumunaniro mukuremerera cycle. Silicon mold casting itangira hafi ya net. Noneho ibigo byacu 5-axis byo gusya bikuraho gusa ibikenewe-kubungabunga imiterere yintete, gukuraho intambwe zo kugabanya imbaraga zo guhagarika umutima, no kugabanya igihe cyo kuyobora ibyumweru 3.7 hamwe nubundi buryo bwakozwe neza. OEM imwe yo muri Amerika y'Amajyaruguru yahinduye umurongo wa cobalt alloy nozzle kuriyi nzira ya Hybrid kandi igabanya igiciro cya 29% mugihe yongereye igihe cya serivisi kuva 8,200 kugeza 14,600.
Icyo abakiriya bahora bibaza - nicyo dusubiza mbere yo gusubiramo - nuburyo twakwirinda uburyo butatu bukunze kunanirwa muburyo bukomeye bwa silikoni ya silicon:
- Microshrinkage mumasangano: Byakemuwe nubushyuhe bwubushyuhe bwa sisitemu yo kwinjiza no kugenzura ubushyuhe bwigihe (± 1.5 ° C) mugihe cyo gusuka - ntakundi.
- Ubuso butagaragara.
- Ibipimo bigenda byiyongera mubice: Byabujijwe kubungabunga igishushanyo mbonera cya Invar igikoresho gihamye no kwemeza buri gishishwa cyimbere cya geometrie hamwe na optique profilometrie mbere yo guterana.
Ntabwo dufata gukina nkibikorwa byihariye. Buri kazi ka silicon molding akazi gakorerwa isuzuma ryubwubatsi: Ese igice cya geometrie cyateguwe neza kugirango gikomere? Ese AMS 5387 isobanura uburyo bwo kuvura ubushyuhe ihuye nubunini bwa casting? Ese Ra 0.4 isabwa kurangiza irashobora kugerwaho nta gusya kwa kabiri bishobora guteza ibyangiritse? Ibi ntabwo ari ibintu byerekana urutonde. Nibiganiro-byanditse, itariki, kandi byometse kumurongo wakazi.
Urebye imbere, icyuho nyacyo ntabwo ari ubushobozi-ni ubujyakuzimu bwemeza. Umwaka utaha, QINGDAO QIANGSENYUAN yaguye ISO 13485 kugirango igere ku rwego rw’ubuvuzi cobalt-chromium orthopedic yo mu rwego rwo kwa muganga, kandi itangira kwemeza-igice cya gatatu kwemeza uburyo bwa silicon yakozwe na NADCAP AC7118 Rev. D kugirango baterwe mu kirere. Kubera iki? Kuberako abakoresha amaherezo batagishoboye kwemera "cyakoze ubushize." Barasaba ibyasubiwemo - kubikoresho, geometrike, hamwe nibikorwa. Iyo ibyawe silicon mold casting uruganda Irashobora gutanga ibice bya pompe AMS 5387 hamwe nubushakashatsi bwuzuye bwa metallurgjique, ibimenyetso byingenzi byemejwe na CMM, na raporo zeru zidahuye mumezi 18 yikurikiranya, ureka kuba umucuruzi. Uhinduka shingiro.
