Ukuchaneka Itafile yokwenza i-sheet metal ayisiyiyo nje indawo yokusebenza-yisiseko somzimba solawulo lwe-dimensional, ukuphindaphinda, kunye nokuzithemba komqhubi. Sibukele iinjineli zihlengahlengisa zonke iiseli zemveliso kuba iitafile zabo zijijekile phantsi kwebhayisekile eshushu. Siye sabona abaqhubi abagobayo benqumama phakathi komjikelo ukuze bavale umsantsa we-0.15 mm-kuphela ukufumanisa ingcambu unobangela yayikukunyuka kwetafile ngaphaya kwe-± 0.2 mm ngaphezulu kwe-1,200 mm. Kumsebenzi wentsimbi ephezulu yokunyamezela, itafile yilapho ijometri iqala khona.
I-Botou Haijun Metal Products Co., Ltd. yakhela amacandelo e-Tier-1 ababoneleli beemoto abalandula iinxalenye ezinonyamezelo ezipakishweyo ezingaphezulu kwe-±0.12 mm. Ukuhlangabezana naloo nto, yonke iprototype bracket, yonke i-sensor etsalwa nzulu yezindlu, yonke indibano edityanisiweyo iqala kumphezulu owenzelwe uzinzo-hayi lula. Oko kuthetha ukuba iipleyiti ezisisiseko zentsimbi ezine-30+ yeminyaka yokuguga okuthomalalisa uxinzelelo, hayi iifreyimu zentsimbi ezidityanisiweyo ezithanda ukutshintshwa kancinci emva komthwalo ophindaphindiweyo. Kuthetha i-granite yomhlaba okanye iiplate eziphezulu zetsimbi eziqinileyo kunye ne-flatness eqinisekisiweyo kwi-ISO 10791-7 i-Class 4 (≤0.015 mm / m), eqinisekisiwe ngokusebenzisa i-laser interferometry-kungekhona izikhombisi zokudayela zodwa. Okona kubaluleke kakhulu, kuthetha ukudibanisa itafile kwinkqubo epheleleyo: I-CNC press brake positioning, i-CMM yokuqinisekisa iindawo ezakhelwe phezulu, kunye neepatheni ze-T-slot ezihambelana neenkqubo zokulungelelanisa umatshini-ozingafakwanga njengengcamango emva.
Abanye banokuthi i-2,000 yeedola zetafile isombulula ingxaki efanayo ne-12,000 yeqonga lobunjineli. Kodwa ekuhanjisweni kwehlabathi lokwenyani, olo qikelelo luyasilela kumanqaku amathathu abalulekileyo. Okokuqala, i-thermal drift: iitafile ze-aluminium ezilula zandisa i-2.3 × ngokukhawuleza kunentsimbi. Ukutshintsha kwe-ambient ye-5°C ngexesha lokuseta kusasa kunokubangela imposiso ye-0.08 mm yendawo yonke kwi-1,000 mm yoyilo-ngokwaneleyo ukungahambi kakuhle iipateni zomngxuma we-robotic welding fixtures. Okwesibini, ukuhanjiswa komthwalo: iitafile eziqhelekileyo azifane zichaze ukuphambuka okuguquguqukayo phantsi kwe500 kg yemithwalo yamanqaku. Silinganise ukuya kuthi ga kwi-0.32 mm sag kwiiyunithi zokungena kwinqanaba lokungena ngexesha elinye lamanqaku amaninzi-ukudlulisa ngokuthe ngqo impazamo kwii-engile zokugoba. Okwesithathu, ingqibelelo yojongano: iipleyiti zesixhobo ezibotiweyo zihlala zingenabhaliso lwedowel-pin, zivumela ulungelelwaniso lutyebe phakathi kokuseta. E-Haijun, zonke iitafile zemveliso zisebenzisa imikhono yentsimbi eqinileyo ene-≤0.005 mm bore-to-pin clearance-kwaye ipleyiti nganye ifakwe kwi-CMM ngaphambi kokukhululwa.
Yintoni eyahlula umphezulu osebenzayo kwinyani Itafile yokwenza i-sheet metal yehla kwizakhono ezine ezingaxoxisiyo:
Ukugcinwa kwe-flatness phantsi komthwalo we-thermal kunye noomatshini: Iqinisekisiwe kwi-25 ° C ± 1 ° C, emva koko ihlolwe kwakhona emva kweeyure ze-8 ze-60 ° C ukukhanya komoya kunye ne-300 kg isasazwa ukulayisha Inkqubo yereferensi yemetroloji edibeneyo: Imingxuma ethungelwe i-M8 kwi-100 mm yegridi, ngokuchaneka kwendawo elandelelwa kwimigangatho ye-NIST Ulawulo lwamandla okubamba: T-slots ezilinganiswe ≥12 kN umthwalo wokubamba nge-100 mm segment, kunye ne-zero enokumetwa ejijekileyo phantsi kwetorque epheleleyo. Isiqinisekiso sokuhambelana kwezinto: Imiphezulu igqityezelwe ukuya kwi-Ra ≤0.4 µm yokuphatha i-stainless kunye ne-aluminium-akukho kukrwela kancinci ngexesha lokudluliselwa kwenxalenye Asithengisi iitafile njengezinto ezizimeleyo. Sizifake kwiindlela zokusebenza zobunjineli. Xa umxhasi woomatshini bezolimo baseYurophu efuna ukuphinda-phinda kwimisebenzi ye-14 yokugoba kwisibiyeli se-chassis esinye, siye sayila itafile ngohlengahlengiso olunobude obuphindwe kabini-icandelo elinye litshixelwe kwi-920 mm ukwenza ngesandla, elinye liyi-850 mm yokulayisha irobhothi-zombini zabelana ngenqwelomoya enye. Xa isihlanganisi esizisebenzelayo saseMntla Melika sidinga i-zero rework kwi-laser-cut mounting plates, siye sanikezela ngeetafile ezinencam yereferensi eyenziwe ngoomatshini ehambelana nobubanzi befiber-laser kerf (±0.02 mm). Oku asikokwenza ngokwezifiso. Kukuphendula okulinganayo okuguqulelwe kwintsimbi kunye negranite.
Jonga phambili: Isizukulwana esilandelayo se Itafile yokwenza i-sheet metal iinkqubo aziyi kubamba nje iinxalenye-ziya kuzilinganisa. Ilebhu ye-R&D ye-Haijun ngoku iqinisekisa iigeyiji zoxinzelelo kunye ne-capacitive displacement sensors ezondla idatha yexesha lokwenyani kwiinkqubo ze-MES. Akunjalo njengento entsha, kodwa njengegalelo lokulawula i-loop evaliweyo: ukuba ukwandiswa kwe-thermal kutshintsha i-Y-axis datum nge-0.03 mm, i-CNC press brake ihlawula ngokuzenzekelayo. Loo nqanaba lokudibanisa lisebenza kuphela xa itheyibhile iyeka ukuba yifenitshala kwaye ibe yinxalenye yesakhiwo somgangatho. Kumaqela okwakha amacandelo apho i-± 0.05 mm inquma ukungaphumeleli kwentsimi-okanye apho i-95% ngexesha lokunikezelwa kwexesha lixhomekeke kwimpumelelo yokuqala-itheyibhile ayikho indawo yokuqala. Sisiqinisekiso esithe cwaka.
