Wonke umshicileli onembayo uyalazi iqiniso: elakho itafula lokwenziwa kwensimbi akuyona nje indawo engaphezulu-kuyisisekelo sokuphindaphinda, ukulawula ukubekezelelana, kanye nokuzethemba komsebenzisi. Sibone izitolo zilahlekelwa yimizuzu engu-12 ingxenye ngayinye lapho zisebenza kabusha ngenxa yokuthi ithebula lazo lalingenakho ukucaba kwangempela noma ukubambelela kwe-modular. Abanye balahle yonke imihlangano ngemuva kokuthi ukuhlanekezela okushisayo kuphazamise isisekelo esiphansi ngesikhathi sokugijima kwe-MIG ephezulu. Ithebula elingakwesokudla "alisizi" i-welding-iqeda okuguquguqukayo ngaphambi kokuba i-arc ishaye.
Kungani I-Flatness, Grounding, kanye ne-Modularity Kungenakubekeka Ebucayini
Ithebula lokwenziwa kwensimbi kufanele lilethe izinto ezintathu okungaxoxiswana ngazo: 0.05 mm/m flatness, Izindlela zokumisa eziphansi ezingaphansi kwe-2 ohms, futhi ukukhweza okuphindaphindekayo phakathi kuka-±0.1 mm. Iningi lamatafula angekho eshalofini liyahluleka kokubili kwalokhu. Sihlole amayunithi angu-17 epaki yezimboni yaseBotou ngekota edlule—mane kuphela ahlangana nawo womathathu. Kungani? Ngoba flatness akukhona mayelana nesigayo finish; imayelana nokukhululeka kokucindezeleka kwangaphakathi ku-base plate. Ukugawula akukona ukubalwa kwebhawodi; imayelana namabha amabhasi aboshwe ngethusi ashiselwe ngqo kuhlaka, angabhawudi ezindaweni ezipendiwe. Futhi i-modularity ihluleka lapho isikhala se-T-slot sikhukhuleka ngaphezu kuka-±0.08 mm ngaphezu kwamamitha angu-2—okwanele ukumisa kabi indlela yethoshi yerobhothi ngo-0.3 mm ekufinyeleleni okungu-1.2 m.
Umphumela womhlaba wangempela? Iklayenti elilodwa lemishini yezolimo lasebenzisa ukuqinisekiswa kwamahora angu-48 ekuhlanganiseni kukabakaki omusha wokulayisha. Ithebula labo elidala libonise ukuhluka okuhlanganisiwe okungu-0.23 mm kuwo wonke amaphuzu ayisithupha we-weld. Ngemva kokushintshela kuplathifomu eqinisekisiwe, ukuhluka kwehle kwafika ku-0.06 mm—futhi isikhathi somjikelezo sehle ngo-19% ngenxa yokuthi o-opharetha bayekile ukuqinisekisa ukuqondanisa nezinkomba zokudayela ngaphambi kwayo yonke into.
Ukuthi Ukukhetha Okubalulekile Kuyithinta Kanjani Ikhwalithi Ye-Weld
Amatafula ensimbi engagqwali amelana nokugqwala—kodwa ahambisa ukushisa ngendlela engafanele, okubangela ukungqubuzana kwendawo eduze kwamashisela omjikelezo omningi. Amathebula e-aluminium aqeda ukushisa ngokushesha—kodwa aguquguquka ngaphansi kwamandla okubamba angu-12 kN, izinto ezishintshayo phakathi nokugijima. Isixazululo esiqinisekisiwe? Insimbi yesakhiwo ejwayelekile ye-S355JR, isuswe ukucindezeleka ku-620°C amahora angu-4, bese ifakwa ngomshini ngokusetha okukodwa kumshini wokugaya we-5-axis gantry.. Lokhu kuletha ukuqina kwe-isotropic, ukunwetshwa kokushisa okubikezelwayo (11.7 µm/m·°C), nokuqina kwendawo okungu-220 HB—okunzima ngokwanele ukumelana nokugojwa kumadiski okugaya, kuthambile ngokwanele ukwamukela okufakiwe okuthenjiwe ngaphandle kokuqhekeka okuncane.
Siyakukala lokhu—hhayi ukulinganisa. Ithebula ngalinye lishiya indawo yethu enesitifiketi se-ISO 9001 nombiko we-CMM obonisa ukuchezuka okucaba okubekwe kumephu kumaphoyinti angama-256. Awekho amanani "ajwayelekile". Azikho izimangalo "ezifika" Idatha eluhlaza nje egxivizwe ngesiginesha yethu kanjiniyela we-QA.
Izindleko Ezifihliwe Zezinhlelo Zokulungisa "Eziguquguqukayo".
Amanye amathebula akhangisa “ukulungiseka okungapheli.” Empeleni, lokho kusho ama-T-slots angu-24 imitha nge-pitch engu-12 mm—futhi akukho ukuphindaphinda kokuma phakathi kwezikhala. Silandelele i-fixture drift ohlelweni olulodwa olunjalo: ngemuva kwemijikelezo engama-87 yokulayisha/yokwethula i-subassembly engu-42 kg, isigxivizo esifanayo sahlala ngo-0.17 mm ngaphansi kwendawo yaso yasekuqaleni. Lokho kwanele ukushintsha ukujula kokungena kwe-weld ngo-18% ku-3 mm okungenabala.
Ukuguquguquka kweqiniso kusho izikhonkwane zendawo ezinenkomba ezinama-chamfer angu-45° aqinile, izimbobo ze-dowel eziphansi ezibanjwe ukubekezelelana kwe-H7, futhi izisekelo zokulungisa ezinemiphetho yereferensi ekabili. Lezi akuzona izengezo-zakhelwe ku-DNA yetafula. Lapho ukhiya into ethile endaweni, uvaleleka eqinisweni elinohlangothi—ungathembi ukuthi amabhawodi azobambeka.
Ukunethezeka kuqinisekisiwe ngokwe-ISO 10791-7, hhayi “ngokucaciswa komkhiqizi ngamunye” Ukumelana nokuphansi kukalwa ngesihloli se-Kelvin esinezintambo ezi-4, hhayi i-multimeter I-T-slot parallelism ihlolwe ngobude obugcwele—hhayi nje phakathi nendawo Ukuqina kobuso kuqinisekiswe ngesikali se-Rockwell B ezindaweni ezintathu ngemitha yesikwele Okudingayo Empeleni Ngaphambi Kokuthenga
Cela izinto ezintathu ngaphambi kokusayina i-PO: (1) Umbiko we-CMM wenombolo yomkhiqizo oqondile ozoyithola—hhayi idatha yeyunithi yesampula. (2) Ama-coefficients wokunweba okushisayo wento eyisisekelo, aqinisekiswe nge-EN 10025-2 ngayinye. (3) Ubufakazi bemingcele yomjikelezo okhulula ukucindezeleka: isikhathi, izinga lokushisa lokushisa, ubude besikhathi sokucwiliswa, kanye nephrofayili yokupholisa. Uma bengakwazi ukukunikeza lezi, hamba. Akukho okuhlukile.
I-Botou Haijun Metal Products Co., Ltd. yakha amatafula okwenziwa kwensimbi kulawa mazinga—hhayi njengesimangalo sokumaketha, kodwa njengesango lokukhiqiza. Iyunithi ngayinye ithunyelwa ngedosi yayo yokuhlola: ukuphrinta kobukhulu, imephu eqinile yendawo (Ra ≤ 0.8 µm), kanye nelogi yokuqinisekisa ephansi. Asiwathengisi amatafula. Siletha izisekelo ezilandelekayo zokunemba.
Ukushisela kwakho okulandelayo kuqala kudala ngaphambi kokuthi kugeleze igesi. Iqala ngengaphezulu eliphethe iqiniso. Khetha ngokufanele.
