Iyo ba injeniyeri bagaragaje 304 ibyuma kubibaya bya hydraulic, amazu ya pompe, cyangwa ibice bya winch byo hanze, ntabwo bahisemo ibikoresho gusa - biyemeje kurwanya ruswa, guhagarara neza, no kwizerwa igihe kirekire mukibazo. Ariko gushakisha ibyo bikoresho ntabwo bihagije. Icyangombwa nuburyo byahinduwe: ubunyangamugayo bwa casting, CNC itomoye, uburyo bwo kuvura ubushyuhe, gukurikiranwa na buri cyiciro gishonga. Aho niho hari ukuri 304 uruganda rukora ibyuma yitandukanya - ntabwo ari nimero ya catalog, ahubwo ni disipuline.
Kuki "Uruganda" rusobanura ibirenze imirongo yumusaruro
A 304 uruganda rukora ibyuma igomba kugenzura urunigi rwuzuye: fagitire zemewe zemewe hamwe na raporo yikizamini (ASTM A240, EN 10088-2), ikirere cyagenzuwe gushonga kubisigazwa bya sulfure nkeya na ogisijeni, hamwe no gutandukanya byimazeyo mugihe cyo gukora kugirango birinde kwanduzanya na karubone cyangwa ibyuma. Twabonye ibice byinshi byananiranye muri serivisi - ntabwo biva muri chimie mbi ya chimie, ariko biturutse kuri passivasi idahuye nyuma yo gusya-axis nyinshi, cyangwa gucamo micro kuri radiyo yimbere imbere kubera inzira yibikoresho byibasiye.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata 304 idafite umwanda ntabwo ari ibicuruzwa, ahubwo ni sisitemu ikora. Ubufindo bwose bukorerwa spark spectrometry verisiyo yo kwakirwa. Imashini ikoresha imisarani yo mu bwoko bw’Ubusuwisi hamwe n’urusyo 5-axis hamwe na coolant-binyuze mu bikoresho - ni ingenzi cyane mu kwimura chip mu byobo byimbitse nko mu nzu ya silindari ya piston. Nta bigufi. Nta buso "bwiza buhagije" burangira. Niba igishushanyo cyawe guhamagarira Ra 0.4 µm mumaso yikidodo, turapima - ntabwo tubigereranya-hamwe na profilometero ya tactile yahinduwe kuri NIST.
Aho Standard 304 Ihurira Inshingano-Ingirakamaro
Bisanzwe 304 ikora kubigega byo murwego rwo kurya. Ntabwo ihita ikora kuri AMS 5387 cobalt-alloy pompe ikora kuri 450 ° C na 350 bar. Nyamara abakiriya benshi badusaba gukora imashini 304 * kuruhande * T800 superalloys kubikoresho bisangiwe. Niyo mpamvu ikigo cyacu gishyira mu bikorwa uturere twinshi: selile yihariye ya CNC idafite ingese, sitasiyo zitandukanye zo gusya, hamwe nibikoresho byerekana amabara. Twabyize inzira igoye-mugihe cyo kugenzura 2022, karbide imwe idasimbuwe yinjizamo ibisigazwa byicyuma cyibumoso ku ntebe ya 304. Igice cyatsinze igenzura-ariko cyananiwe kugerageza umunyu-spray kumasaha 96. Isomo ryashyizwemo: ubuziranenge bwa metallurgical butangira mbere yo gukata bwa mbere.
Ibyifuzo byacu 304 bikunze kwerekana ingingo zifatika-zisi: imibiri ya valve umubiri usaba kwibanda cyane (<0,015 mm) hagati yicyambu gisohoka; urufatiro rwa pompe rukeneye uburinganire muri mm 0,05 hejuru ya mm 600; na winch center shaft umuzingo ukorerwa imitwaro ya cyclic torsional. Ibi ntabwo ari ibintu byimigabane. Nibo GD & T-biremereye, hamwe no kwihanganira imyanya yerekanwe kumiterere ya datum ikozwe muburyo bumwe - ntabwo ari bitatu. Ibyo bisaba gahunda yo guteranya-gutunganya imashini, ntabwo ari intoki zikurikirana.
Niki "Gukora Customer Manufacturing" Mubyukuri bitanga
"Kwizerwa" bivuze ko prototype yawe igera muminsi 18 - ntabwo "mubyumweru 3-4." Bivuze ko ubona raporo ya CMM yerekana na nominal nyirizina kubipimo byose bikomeye - ntabwo ari kashe kurutonde. Bishatse kuvuga ko mugihe injeniyeri wawe yerekana ibishobora kwivanga mugushushanya inteko, dukoresha kwigana ibyuma bya digitale * mbere yo * guca ibyuma - hanyuma tugasaba ko hahindurwa radiyo 0,03 mm ikiza amadolari 12,000 yo gutunganya umurima.
Ntabwo dusohora casting, kuvura ubushyuhe, cyangwa ubugenzuzi bwa nyuma. Ikigo cyacu cyujuje ISO gikora ishoramari ryamazu 304 yoroheje, guta umucanga kubishingwe binini bigera kuri 800, hamwe nigisubizo cyakorewe nyuma yo gutanura mu ziko rishobora gukoreshwa hamwe na ± 3 ° C. Buri casting ibona RT cyangwa UT igenzura kuri ASTM E94 / E165. Igice cyose cyakorewe imashini kiboneka, kigaragara, kandi cyemewe-harimo gupima umuvuduko kugeza 1.5 pressure umuvuduko wakazi kumibiri ya valve.
Uku kwishyira hamwe guhagaritse gukemura ikibazo kinini cyububabare twumva mumakipe atanga amasoko: gutunga urutoki hagati yimishinga, iduka ryimashini, hamwe na coater mugihe igice cyatsinzwe. Hamwe numufatanyabikorwa ubazwa, gusesengura imizi-bifata amasaha-ntabwo ari amezi.
Guhitamo Kurenga Urupapuro
Baza umuguzi w'inararibonye: itandukaniro riri hagati yinganda ebyiri 304 zidafite ingese akenshi ziri mubiti byananiranye - ntabwo ari udutabo twabo. Kuri QINGDAO QIANGSENYUAN, data base yimbere idakora neza ikurikirana uko gutandukana: 72% bifitanye isano no kugoreka ibintu biterwa no kugoreka ibintu ku buryo bworoshye; 18% bituruka kubushyuhe budahagije mbere yo gusudira gusana imyanda; 10% birimo gusobanura nabi GD&T guhamagarwa kumurage. Turasangiye ubu bushishozi - ntabwo ari kwamamaza, ahubwo ni tekinoroji ya tekinoroji.
Niba gahunda yawe itaha ikubiyemo ibyuma 304 bidafite ibyuma bya sisitemu ya hydraulic, amavuta ya gaze na skide, cyangwa ibinyabiziga bya injeniyeri, saba ibirenze amagambo. Baza kuri: urusyo rufite numero yubushyuhe, dosiye ya porogaramu ya CMM yo kugenzura ingingo ya mbere, hamwe nibimenyetso byerekana buri mwaka wa kalibibasi ya buri mwaka kubikoresho byose bya metrologiya. Noneho gereranya - ntabwo ari igiciro gusa, ahubwo ni nyirubwite.
A 304 uruganda rukora ibyuma igenzura imyitwarire ya alloy mukibazo, igenzura buri gihinduka kuva gushonga kugera kubipimo, kandi ifata igishushanyo cyawe nkamasezerano-ntabwo ari igitekerezo-cyinjiza inshuro nyinshi. Ntabwo binyuze mu masezerano. Binyuze mubikorwa byemejwe, byanditse, bisubirwamo.
