Gutera ibyuma bitanga ibisobanuro bisubirwamo aho umusenyi utera umusenyi - cyane cyane kubice nkibikoresho byumuvuduko wamazi wa hydraulic, inzu ya pisitori ya pisitori, hamwe na cobalt-alloy nozzles bisaba kwihanganirana cyane, microstructure idahwitse, hamwe na zeru zingana na zeru mubice. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoresheje inzitizi zirenga 12,000 zo guta ibyuma kuva mu mwaka wa 2018 - ntabwo ari imyitozo ngororamubiri, ariko kugira ngo dukemure ibyananiranye nyabyo: kurwanira mu musingi wa pompe ya T800, gushira mu mubiri wa AMS 5387, hamwe no guturika hejuru mu gihe cyo kuvura ubushyuhe bwa shitingi. Buri kunanirwa kwatwigishije ibyo ibitabo bisiba: kugenzura ubushyuhe bwubushyuhe burenze ibintu bisukuye; igishushanyo mbonera cyerekana ubuzima bw'umunaniro kuruta imbaraga zingana; kandi mbere yubushyuhe burigihe birinda 73% byigice cyambere mugice cya nikel.
Impamvu Gukora Ibyuma Byatsinze Iyo Precision Atari Umushyikirano
Gutera umucanga bikora kubice bike, kwihanganira bike. Ariko mugihe ibice byawe bigomba gufata mm 0,05 mm kumurambararo wa mm 320 ya diametre - cyangwa kurokoka 15 000 psi mu guteranya pompe yamavuta - guteramo ibyuma biba inzira yonyine. Ibyuma byayo bikomeye cyangwa ibyuma bikozwe mubyuma birwanya kwaguka kwubushyuhe, gutanga igipimo kimwe cyo gukonjesha, kandi bikuraho impinduka ziranga umusenyi uhujwe. Dupima buri munsi: ibyuma byacu byerekana ko 42% bitagabanije kugabanuka ugereranije nuburinganire bwumusenyi uhwanye, kandi urufatiro rwa pompe rwicyuma rutagira umuyonga rugera kuri Cpk 671.67 kumuhamagaro wa GD&T - nta gutunganya kabiri.
Kwishura ntabwo ari ibipimo gusa. Ibishushanyo byuma bifasha icyerekezo gikomeye. Twerekeje ibishushanyo bihagaritse inzu ya piston, duhatira ibyuma byo kugaburira hejuru uhereye hejuru. Ibi bivanaho umurongo wo hagati mubice byimbitse - ingingo idahwitse yo kunanirwa kumusenyi uhwanye. Kuri cobalt-nikel ivanze nka AMS 5387, iryo hinduka rimwe ryagabanije icyuho cyimbere ku gipimo cya 91% mubigenzuzi bya NDT. Nta gipfundikizo, nta gihuza, nta gukeka - gusa fiziki, igenzurwa.
Aho Bitsinzwe - nuburyo bwo kwirinda imitego
Bamwe bavuga ko guteranya ibyuma bidahinduka cyane kuburyo buke bwo gukora. Bafite ukuri-niba ubifata nko guta umucanga. Ariko guhinduka biva mubishushanyo mbonera, ntabwo ari ibikoresho. Twatanze prototypes ikora muminsi 11 dukoresheje ibikoresho-byihuse byuma bya T800 alloy nozzles. Amayeri? Ibikoresho byujuje ibyangombwa byinjijwe bikozwe mu byuma bya H13, byabanje gukomera kugeza kuri 48 HRC, hamwe n’ibyambu bya termocouple byahujwe no kugenzura igihe nyacyo. Ayo makuru agaburira muburyo bwo kwigana - bityo isuka ya kabiri ihuye niyambere, ndetse no kuri 50.
Umutego wukuri wigiciro ntabwo ukoresha - ni ukwirengagiza imikoranire ya metallurgji. Twigeze kubona igishushanyo cyerekana "ASTM A487 Grade CA6NM ibyuma bitagira umuyonga" kugirango umusingi wa pompe wamazi. Ibisobanuro byari ukuri. Iyicwa ntiryari: gukonjesha ibicuruzwa bitagenzuwe byateje sigma icyiciro cyimvura kumupaka wingano. Umusaruro wagabanutse kugera kuri 38%. Umuti? Twahinduye kuzimya ikirere cyagenzuwe imbere mu cyuho, hanyuma twongeramo 1050 ° C yumuti hamwe no kuzimya amazi. Umusaruro wasimbutse kugera kuri 94%. Isomo: guteramo ibyuma ntibisimbuza disipuline-byongera ingaruka zabyo.
Nigute QINGDAO QIANGSENYUAN Yihuza Gukina hamwe nukuri-kwisi
Ntabwo dutandukanya casting n'imikorere. Ba injeniyeri bacu basubiramo buri kintu cya GD&T - ntabwo ari ugukora wenyine, ahubwo ni inzira yumurimo wa serivisi. Umubiri wumuvuduko wumubiri ntabwo ari imiterere gusa; ni umuyoboro uhangayitse. Twashizeho rero ibipimo byerekana ibipimo byerekana umusaruro ushushanya ikarita yumuriro mugihe cyo gukomera. Ayo makuru aratubwira aho imihangayiko isigaye izibanda-hamwe n’aho twakongeramo imashini itunganya imashini cyangwa nyuma yo kugabanuka-kugabanuka.
- Cobalt-alloy nozzles: Shira mubishushanyo bya H13 byashyutswe kuri 550 ° C, hanyuma ukonjesha ikirere kugirango wirinde gucika intege.
- Imashini ya winch shafts: Ibice byumucanga byinjijwe mubyuma kugirango bigenzurwe na geometrike - igishishwa cyo hanze, igikomangoma cyimbere imbere.
- Inzu ya hydraulic inzu: Imashini itaziguye kuva as-reta ukoresheje munzu 5-axis CNC-nta kongera guhuza, nta datum ihinduka
Uku kwishyira hamwe kugabanya igihe cyo kuyobora 30% hamwe na casting ikurikirana + abatanga imashini. Icy'ingenzi cyane, iremeza ko ikurikiranwa: buri kintu gitwara amateka yuzuye yubushyuhe, isesengura ry’imiti, na raporo y’ubugenzuzi bwa CMM - bifitanye isano n’ibikoresho fatizo biva mu ruganda rwemewe.
Guhitamo Mugenzi wawe - Hanze y'agatabo
Baza uwaguhaye isoko kubijyanye n'ubushobozi bwabo bwo guta. Noneho baza ibibazo bitatu bikurikirana: Nubuhe buryo bukoreshwa cyane kuri AMS 5387? Nigute ushobora kwemeza ubushyuhe bwububiko mbere yo gusuka? Urashobora gusangira raporo ya FAI iheruka kwerekana yerekana-ibipimo byanyuma ku gice hamwe na ≥5 bikomeye bya GD&T?
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibisubizo byacu birapimwa: 8.200 bisuka kumurongo umwe wa T800 nozzle; infrared pyrometer yemewe kumanota 3 kuri cavit, yinjiye byikora; na raporo ya FAI yerekana 0,012 mm igereranije itandukanijwe kumanota 12 ya silindrike yiruka kuri 280 mm ya pompe. Ntabwo tubitangaza nkubucuruzi - ariko kuberako ibyuma byubatswe byatsinze bibaho mumibare, ntabwo byasezeranijwe.
Kubisabwa aho gutsindwa bisobanura igihe, umutekano, cyangwa kutubahiriza amategeko -icyuma ntabwo ari amahitamo. Nibyingenzi. Kandi umufatanyabikorwa mwiza akora itandukaniro hagati yisubiramo risubirwamo no gukora cyane.
