Ukunemba itafula lokwenziwa kwensimbi yeshidi akuyona nje indawo yokusebenza-iyisisekelo esibonakalayo sokulawula ubukhulu, ukuphindaphinda, kanye nokuzethemba komqhubi. Sike sabuka onjiniyela belinganisa kabusha wonke amaseli okukhiqiza ngenxa yokuthi amatafula abo asonteka ngaphansi kokuhamba ngamabhayisikili ashisayo. Sibone o-opharetha abagobayo bemisa isikhashana phakathi nomjikelezo ukuze kukhanye igebe elingu-0.15 mm—ukuthola kuphela imbangela kwakuwukushibilika kwetafula ukukhukhuleka ngaphezu kuka-±0.2 mm ngaphezu kuka-1,200 mm. Emsebenzini wensimbi weshidi lokubekezelela okuphezulu, itafula yilapho i-geometry iqala khona.
I-Botou Haijun Metal Products Co., Ltd. yakha izingxenye zabahlinzeki bezimoto be-Tier-1 abenqaba izingxenye ezinenqwaba yokubekezelela izinto ezedlula ±0.12 mm. Ukuze kuhlangatshezwane nalokhu, yonke i-prototype bracket, zonke izindlu zezinzwa ezidonsa ngokujulile, yonke inhlangano eshiselwe iqala endaweni eyakhelwe ukuzinza—hhayi ukuba lula. Lokho kusho ukuthi amapuleti esisekelo ensimbi aneminyaka engu-30+ yokuguga okudambisa ingcindezi, hhayi amafreyimu ensimbi ashiselwe athambekele ekushintsheni okuncane ngemva kokubopha okuphindaphindiwe kwemithwalo. Kusho igwalagwala eliphansi noma amapuleti angaphezulu ensimbi aqinile ane-flatness egunyazwe ku-ISO 10791-7 Class 4 (≤0.015 mm/m), aqinisekiswe kusetshenziswa i-laser interferometry—hhayi izinkomba zokudayela zodwa. Okubaluleke kakhulu, kusho ukuhlanganisa ithebula kunqubo egcwele: I-CNC press brake positioning, amaphuzu okuqinisekisa e-CMM akhelwe phezulu, kanye namaphethini we-T-slot aqondaniswe nezinhlelo zokudidiyelwa komshini—azifakwanga njengokucatshangelwa kwamuva.
Abanye bangase baphikise ngokuthi ithebula le-modular engu-$2,000 lixazulula inkinga efanayo nenkundla engu-$12,000 yobunjiniyela. Kepha ekusetshenzisweni komhlaba wangempela, lowo mcabango wehluleka kumaphuzu amathathu abalulekile. Okokuqala, i-thermal drift: amatafula e-aluminium angasindi anwebeka ngo-2.3× ngokushesha kunensimbi. Ukushintsha kwe-ambient okungu-5°C ngesikhathi sokusethwa kwasekuseni kungabangela iphutha lokuma elingu-0.08 mm kusakhiwo sonke esingu-1,000 mm—okwanele ukumisa kabi amaphethini embobo okulungiswa kokushisela irobhothi. Okwesibili, ukusatshalaliswa komthwalo: amathebula ajwayelekile awavamile ukucacisa ukuchezuka okuguquguqukayo ngaphansi kwemithwalo yamaphoyinti angu-500 kg. Silinganisele kufikela ku-0.32 mm kumayunithi ezingeni lokungena phakathi nokuhlanganisa amaphuzu amaningi—sidlulisela iphutha ngokuqondile kuma-engeli agobile. Okwesithathu, ubuqotho besixhumi esibonakalayo: amapuleti amathuluzi afakwe ibhawudi avamise ukuntula ukubhaliswa kwephinikhodi, okuvumela ukuqondanisa kungene phakathi kokusetha. E-Haijun, wonke amatafula okukhiqiza asebenzisa imikhono yedowel yensimbi eqinile eno-≤0.005 mm bore-to-pin clearance—futhi ipuleti ngalinye lidwetshwe nge-CMM ngaphambi kokukhishwa.
Yini ehlukanisa indawo esebenzayo neyiqiniso itafula lokwenziwa kwensimbi yeshidi yehlela emandleni amane angaxoxiswana:
Ukugcinwa kwe-flatness ngaphansi komthwalo oshisayo nowemishini: Kuqinisekiswe ku-25°C ±1°C, bese kubhekwa kabusha ngemva kwamahora angu-8 okuchayeka komoya okungu-60°C kanye no-300 kg wokulayisha okusatshalalisiwe Isistimu yereferensi ye-metrology ehlanganisiwe: Izimbobo ezishumekiwe ze-M8 kumagridi angu-100 mm, ezinokunemba kokuma okulandelekayo kumazinga e-NIST Ukuphathwa kwamandla okubamba: Ama-T-slots alinganiselwe ngokulayisha okungu-≥12 kN okubamba ngesegimenti ngayinye engu-100 mm, anokusonteka okungalinganiseki okunguziro ngaphansi kwetorque egcwele Isiqinisekiso sokuhambisana kwezinto: Indawo iqedwe ukuya ku-Ra ≤0.4 µm yokubamba i-stainless ne-aluminium—akukho ukuklwebheka okuncane ngesikhathi sokudlulisa ingxenye Asiwathengisi amatafula njengezinto ezizimele. Siwashumeke ekuhambeni komsebenzi wobunjiniyela. Lapho iklayenti lemishini yezolimo yase-Europe lidinga ukuphindaphindwa kokusebenza kokugoba okungu-14 kubakaki be-chassis eyodwa, saklama ngokuhlanganyela itafula elinendawo ekabili yokulungiswa kobude—ingxenye eyodwa ikhiywe ku-920 mm ukuze yenziwe mathupha, enye ku-850 mm ukuze ilayishwe irobhothi—zombili zabelana ngendiza eyodwa ye-datum. Lapho isihlanganisi se-automation saseNyakatho Melika sidinga ukungasebenzi kabusha kweqanda eliziro kumapuleti akhwezayo asikwe nge-laser, sinikeze amathebula anemiphetho yereferensi yomshini wangaphambi komshini afana nobubanzi bekerf ye-fiber-laser (±0.02 mm). Lokhu akukhona ukwenza ngendlela oyifisayo. Ukuziphendulela kobukhulu obuhunyushwe kunsimbi negwadle.
Bheka phambili: Isizukulwane esilandelayo se itafula lokwenziwa kwensimbi yeshidi amasistimu ngeke nje abambe izingxenye-azozikala. Ilebhu ye-R&D ka-Haijun manje isiqinisekisa amageji ohlobo olushumekiwe kanye nezinzwa zokufuduka ezinamandla eziphakela idatha yesikhathi sangempela sokucaba kumasistimu e-MES. Hhayi njengento entsha, kodwa okokufaka kokulawula iluphu evaliwe: uma ukunwetshwa okushisayo kushintsha i-datum ye-Y-axis ngo-0.03 mm, ibhuleki lokucindezela le-CNC linxephezela ngokuzenzakalelayo. Lelo zinga lokuhlanganisa lisebenza kuphela lapho ithebula liyeka ukuba yifenisha futhi liba yingxenye yezakhiwo zekhwalithi. Ezingxenyeni zokwakha amaqembu lapho u-±0.05 mm enquma ukwehluleka kwenkambu—noma lapho u-95% wokulethwa ngesikhathi encike empumelelweni yokuqalisa—ithebula aliyona indawo yokuqala. Kuyisiqinisekiso esithulile.
