Izinkundla zokushisela akuwona nje amatafula ensimbi—ziyisisekelo sokunemba kobukhulu, ukuphindaphindeka, kanye nokuphuma kwezinto ekwenziweni kwensimbi okunembayo kweshidi. Sibone izitolo eziningi zijaha isivinini ngenkathi zidela ubukhulu, kuphela zalahla u-12% wemihlangano eqhutshwa okokuqala ngesikhathi sokufaneleka kokugcina. A iqiniso isiteji sokushisela lenza izinto ezintathu okungekho ibhentshi lomsebenzi elijwayelekile elingakwazi: ukukhiya ingxenye yejiyomethri ngaphansi kwengcindezi eshisayo, igcina flatness engu-±0.15 mm phakathi kwezingu-2,000 mm, futhi ihlanganisa ngaphandle komthungo nokugoba kwe-CNC kanye nokuqoshwa kwerobhothi—ngaphandle kokusebenza kabusha.
E-Botou Haijun Metal Products Co., Ltd., sakha izinkundla zokushisela hhayi njengezinto ezizimelayo—kodwa njengezixhumanisi eziklanyelwe phakathi kwenhloso yomklamo kanye neqiniso lesitezi sesitolo. Yonke inkundla iqala ngombuzo amakhasimende awubuzayo ngaphambi kokucaphuna: “Ingabe lokhu kuzobekezelela lapho sishisela ama-flange amane ku-180°C?” Impendulo yethu ayilona ithiyori. Iqinisekiswa kuwo wonke amarun okukhiqiza angu-378—kusuka kubakaki bezinto zezolimo eziwugqinsi ongu-12 mm kuya kuzindlu zezinzwa zensimbi engagqwali emigqeni ezenzakalelayo eqinisekisiwe ye-EU. Sisebenzisa amapuleti esisekelo ensimbi enziwe abandayo e-Q345B, anciphisa ingcindezi ku-620°C amahora angu-4, bese aphansi aze afike ku-0.08 mm/m flatness. Ayikho insimbi. Ayikho i-laminate eboshiwe. Ukuzinza kwe-monolithic nje.
Ukwehluleka okuningi kubuyela emuva ekubhekeni okukodwa: ukuziba ukuphathwa kwendlela yokushisa. Ukushisela akuhlanganisi insimbi kuphela—kuyayihlanekezela. Iplathifomu eqinile engaqinile ivumela ukushisa kuthuthele kusisekelo, ezindaweni ezisontekile zedatum phakathi kwamasekhondi angu-90. Simelana nalokhu ngomklamo wezendlalelo ezimbili: ipuleti eliyisisekelo elingu-40-mm-thick lokuqina, kanye nepuleti legridi lesibili elingu-12-mm elinamashaneli okupholisa angama-25-mm-diameter agaywe ngokuqondile ngaphansi kwezindawo zokushisela. Ukugeleza komoya akuyona inketho—kuyabalwa. Ngokuhlanganisa i-aluminium, sishiya isikhala sesiteshi sibe ngu-18 mm futhi sengeze izikhonkwane zendawo ezinekhopha ezichitha ukushisa okungu-3.2× ngokushesha kunensimbi evamile. Amakhasimende asebenzisa ozimele bezimoto abanomjikelezo omkhulu abika ngo-41% ukulungiswa okumbalwa kwangemva kokushisela lapho eshintsha esuka kumathebula ajwayelekile aye ezinkundleni zethu eziphethwe ngokushisa.
Ukuhlanganisa kubaluleke ngaphezu kokuzihlukanisa. Iplathifomu yokushisela kufanele ikhulume ulimi olufanayo nebhuleki lakho lokucindezela kanye ne-laser cutter. Lokho kusho ukuthi amasistimu wokuxhumanisa athobela i-ISO 841 afakwe ngomshini ngqo phezulu—hhayi amapuleti amathuluzi angeziwe. Sigaya imigodi ye-datum engu-0.5-mm-deep ngezikhawu ze-X/Y ezifanayo nezindawo ezivamile zomsuka we-CAD (isb., amagridi angu-100 × 100 mm), bese sishumeka okufakwayo kwensimbi eqinile njalo ngo-500 mm ukuze kufakwe izinto eziphindaphindwayo. Akukho ukuqagela. Awekho ama-shims. Lapho umphakeli we-Tier-1 e-Michigan edinga ukuvumelanisa i-fiber laser yakhe entsha namaseli e-MIG erobhothi akhona, basebenzisa izimbobo zereferensi ezakhelwe ngaphakathi zenkundla yethu ukuze bafinyelele ukuvumelanisa okungu-0.03 mm emishinini emithathu yonkana—oqinisekiswe ngokuskena kwe-CMM, hhayi ukuqondanisa okubonakalayo.
Imikhawulo yomhlaba wangempela ibumba izixazululo zangempela. Sithumele izinkundla kumakhasimende azidingayo ukuthi zisebenze ezinsukwini eziyi-11—hhayi amaviki ayi-11. Lokho kudinga ukuhlanganiswa okuqondile: ukugxiviza uhlaka oluyisisekelo endlini, ukwenza imishini kuzikhungo zethu ze-CNC ze-axis engu-5, ukushisela ngezinqubo eziqinisekisiwe ze-GMAW, nokuqeda nge-zinc-nickel plating—konke ngaphansi kophahla olulodwa. Akukho ukubambezeleka okuvela eceleni. Awekho ama-handoffs wekhwalithi. Sihlola inkundla ngayinye ngomthwalo ongu-200-kg osakazwa emagumbini amane, bese sikala ukuchezuka endaweni emaphakathi. Kuyamukeleka? ≤0.12 mm. Ukwehluleka? Ngaphansi kuka-0.7% kukho konke ukuthunyelwa kuka-2023–2024. Futhi ngenxa yokuthi siphatha i-prototyping phansi kuya kumayunithi angawodwa, onjiniyela abawalindi ama-MOQ. I-OEM eyodwa yezolimo yaseJalimane yasebenzisa ukuphindaphinda kwedizayini okuthathu ohlelweni lwethu lwengxenyekazi eyimodulayo—ngalinye linokulungiselelwa okuhlukile kokubopha—ngaphambi kokukhiya ijiyomethri yokugcina. Isikhathi esidlulile siphelele: izinsuku eziyi-19.
A isiteji sokushisela izuza inani layo hhayi emibhalweni emile, kodwa ngendlela eqeda ngayo ukusebenza kabusha, icindezela isikhathi somjikelezo, futhi yenza ukubekezelelana okuqinile kuphindaphindeke—hhayi okukhethekile. E-Botou Haijun, siphatha yonke inkundla njengento eyenza inqubo, hhayi ifenisha. I-flatness ihlala izinzile ngemva kwemijikelezo yokushisela eyi-12,000. Ukuhlanekezela okushisayo kuhlala ngaphansi kuka-0.05 mm imitha ngalinye ngisho nangesikhathi sokushintshwa kwamahora angu-8. Futhi lapho iphrojekthi yakho elandelayo idinga kokubili ukunemba kanye nesivinini, inkundla ngeke ibe ibhodlela—kuyoba isizathu sokuthi ufinyelele usuku lokuqalisa.
