Gusudira kuri platifomu bisaba ibirenze ubushyuhe nicyuma cyuzuza. Niho ubunyangamugayo bwubaka buhura ninzira nyayo yisi-aho imitwaro idahuye ishobora gushora mubikorwa bihenze, gutinda gutangira imirimo, cyangwa bibi, kunanirwa kumurima mukibazo cya cycle. Muri Botou Haijun Metal Products Co., Ltd., twasohoye urutonde rusaga 12,000 rwo gusudira murwego rwa chassis yubuhinzi, ibikoresho byubwubatsi, hamwe nubufasha bwifashishwa bwa convoyeur. Ibyo twize ntabwo ari theoretical: byanditswe muri raporo zacu DFM, gutwika ibiti, no gupima kugoreka nyuma ya weld.
Imyiteguro yabanjirije gusudira ntabwo iganirwaho-Ntabwo ari ngombwa
Ibikoresho byinshi byo gusudira kunanirwa bitangira mbere yuko arc ikubita. Turabibona inshuro nyinshi: amatsinda asimbuka guhuza igenzura, gufata ibintu neza, cyangwa kwirengagiza impinduka zingana ninganda zicyuma. Ku kigo cyacu cya Botou, inteko yose iterana itangirana na cheque eshatu zidashobora kuganirwaho:
Kwihanganira icyuho ≤ 0.5 mm hejuru yuburebure bwuzuye-bupimirwa hamwe na galeri yipima * mbere * gufatana, ntabwo nyuma Ubushyuhe bw'icyuma ≥ 10 ° C. ahantu hakonje; munsi yibyo, shyushya kuri 50 ° C kubyuma bya karubone, 100 ° C kuri 304 bitagira umwanda - byagenzuwe hamwe na trometero ya infragre kuri point eshatu kuri metero Isuku yo hejuru yemejwe na solvent wipe + ikizamini cyimyenda yera: nta bisigara bigaragara, nta mavuta yo gutunga urutoki, nta mukungugu usya wafatiwe mu mwobo Twigeze gusiba inteko 17 zifatanije kubera ko icyiciro kimwe cyicyuma kizunguruka gikonje cyageze hamwe nubunini bwurusyo rudahuye. Igice cya oxyde cyavunitse kimwe mugihe cya GMAW, gitera micro-porosity mumizi. Noneho, ibiceri byose byinjira bikorerwa isesengura ryerekana uburinganire bwa oxyde-kandi duhindura gazi ikingira (kuva 18 L / min kugeza 22 L / min) mugihe itandukaniro ryibipimo rirenga ± 0.3 µm.
Guhitamo Inzira byerekana imikorere yuburyo
Guhitamo hagati ya FCAW, GMAW, na SAW ntabwo bijyanye n'umuvuduko-ni uguhuza ibyinjira mubushuhe kuri geometrie, ubunini bwibintu, hamwe no gupakira serivisi. Kububiko bwa platifomu ifite mm6 mm yuburebure bwurukuta hamwe no gukomeza kuzuza kwuzuza, dusanzwe kuri flux-cored arc gusudira dukoresheje insinga ya E71T-1. Kubera iki? Sisitemu ya slag yihanganira itandukaniro rito ryiza kuruta insinga zikomeye, kandi igipimo cyayo kinini cyo kugabanuka kigabanya ubuso bwibasiwe nubushyuhe (HAZ) ubugari bwa 22% na GMAW kuri amperage imwe.
Ariko kuri platifike yoroheje-nkibikoresho bya aluminiyumu ya sisitemu yo kwishyiriraho izuba - duhindukira kuri GMAW ya pulsed hamwe na 1.2 mm ER5356 insinga. Umuvuduko wa pulse uguma kuri Hz 120; umuyoboro wimpinga ufunze kuri 145 A. Ibi birinda gutwikwa kumpapuro ya mm 2,5 mugihe ukomeza ubujyakuzimu bwa mm1.8. Bamwe bashobora kuvuga ko MIG "yoroshye" kuri aluminium. Ariko, tutiriwe tugenzura impiswi, twapimye 37% byikigereranyo cyo kugoreka no 4 × kurenza urugero mubihe bitose - byagenzuwe hakoreshejwe ibizamini bya radiografiya kuri 120 weld.
Ingamba zo gufata ingamba zigena ihame ryimiterere
Clamps ntabwo ifata ibice-bikemura ibibazo bisigaye. Ibyago byacu byintambara byabaye kuri metero 3.2 yubuhinzi: C-clamps esheshatu zingana zingana zashizeho uburyo bwo kwifata, bigatuma kugoreka hanze hagati. Ubu dukoresha clamping ikurikiranye: banza ukosore impande za datum, hanyuma ushyireho clamps zireremba kuri 300-mm intera iringaniye na flanges ya datum, turekura buri clamp * nyuma * ikonje yegeranye ikonje kugeza kuri 60 ° C. Kamera yubushyuhe yemeza ko ibyo bigabanya kugoreka inguni 65% na clamping static.
Twashyizemo kandi ibibanza byorohereza-0,8 mm z'ubugari, gukata na laser - hafi yinzibacyuho ihindagurika. Izi zikora nkinzira zagabanijwe zo kugabanya ibibazo mugihe cyo gukonja. Mubikoresho bimwe byubwubatsi, wongeyeho ibibanza bitatu bya mm 12 byagabanije gutandukana nyuma ya weld kuva kuri 2,1 mm / m kugeza kuri 0.4 mm / m - utabanje gukora imashini.
Ubugenzuzi bugomba kurenga cheque igaragara
Igenzura ryerekanwa rifata 41% gusa yinenge zikomeye zo gusudira, nkuko amakuru ya NDT yimbere muri 2022–2023 abitangaza. Tugomba kugenzura ibyiciro bitatu:
Gukurikirana igihe nyacyo: Imashini zose zo gusudira za robotic log voltage, ikigezweho, umuvuduko wurugendo, nigipimo cyo kugaburira insinga kumurongo wa mm 50. Gutandukana> ± 3% bitera guhagarara byikora Iyemezwa rya post-weld. Ikizamini cyimikorere: Bisanzwe 5% yumusaruro wihanganira 1.5 × umutwaro wagenwe kumasegonda 120. Dupima gutandukana kumunani - ntabwo ari byinshi gusa, ariko buhoro buhoro kurwego Iyi disipuline yafashe ikibazo cyagarutsweho cyane mu gusudira kwimbitse: gushobora kwemerwa kugaragara kugaragara nko kubura guhuza hamwe na radiyo ishushanyije. Igeragezwa rya Ultrasonic ryerekanye 92% by'ibyo gusudira byari bifite ubutaka bwo munsi. Twongeye gushushanya geometrike ihuriweho - twongeraho 0,5 mm yumuzi mumaso no kugabanya harimo inguni kuva 75 ° kugeza 65 ° - hanyuma dukuraho inenge.
Gusudira kuri platifomu ni sisitemu - ntabwo ari intambwe
Gusudira kuri platifike bigenda neza mugihe igishushanyo, guhitamo ibikoresho, gukora ibikoresho, kugenzura ibikorwa, no kugenzura bikora nka sisitemu imwe. Kuri Botou Haijun, dufata urubuga rwose nkibinyabuzima bitwara imitwaro - ntabwo ari icyegeranyo cyibice byasuditswe. Ibikorwa byacu byujuje ISO bikubiyemo ibitekerezo bya DFM * mbere yo * gusubiramo, impamyabumenyi yo gusudira * mbere yo gusohora ibikoresho, hamwe nibikoresho byerekana * hamwe nibyoherejwe *. Ntabwo tugurisha gusudira. Dutanga ibyemezo byuburyo bukomeza.
Kuri ba injeniyeri bagaragaza gusudira kuri platifomu, tangira hano: sobanura inzira yumutwaro ubanza, hanyuma uhitemo geometrie ihuriweho, hanyuma uhuze inzira na metallurgie - ntabwo ihinduka. Ihinduranya ryonyine rigabanya imirimo ya 38%, hashingiwe ku makuru 2023 avuye mu mishinga 47 y'abakiriya. Gusudira kuri platifomu ntabwo ari uguhuza ibyuma. Nibijyanye no kwemeza imbaraga zohereza-mubihe, ibihe, imyaka mirongo.
