Wonke umshicileli onembayo uyalazi iqiniso: elakho itafula lokwenziwa kwensimbi akuyona nje indawo engaphezulu-kuyisisekelo sokuphindaphinda, ihange lokulawula ukubekezelelana, kanye nomugqa wokuqala wokuzivikela ngokumelene nokusebenza kabusha okubizayo. Sibone izitolo zilahlekelwa izinsuku ezintathu ekuhlanganiseni kukabakaki owodwa ngenxa yokuthi ukuqondisa kwe-T-slot kwetafula kuye kwakhukhuleka ngo-0.15 mm ngokuhamba kwesikhathi. Sike sabuka amajigi e-laser-cut jigs eguquguquka ngaphansi komthwalo oshisayo lapho i-base plate intula insimbi yesakhiwo eqinile. Ukunemba akuqali kuthoshi—kuqala lapho ingxenye ithinta itafula.
Kungani Ubuqotho Bezinto Zibalulekile Kunamaphethini eBolt
Abathengi abaningi bayaqhathanisa itafula lokwenziwa kwensimbi imininingwane ngesisindo, usayizi, noma inombolo ye-T-slots. Lokho kufana nokwahlulela injini ngebheji yehood yayo. Yini empeleni enquma ukunemba kwesikhathi eside ukuzinza kwe-metallurgical. Insimbi egoqelwe ebandayo ye-A572 yeBanga lama-50—ifakwe ukushisa kufika ku-220–250 HB—imelana nokuguqulwa okuncane ngaphansi kwemithwalo yokubopha ephindaphindiwe. Amatafula ensimbi angakapheki athambile aguquguquka ngokubonakalayo kokuthi 1.2 kN/m²; amapuleti aqinile abamba ukucaba ngaphakathi ±0.08 mm endaweni engu-2,000 × 1,500 mm ngemva kwezinyanga ezingu-18 zokusetshenziswa kwansuku zonke. Lokhu siqinisekisa ngokushanela kwe-CMM njalo ngekota—hhayi nje ukuhlola kokuqala kokwamukela. Ama-gradients okuqina kobuso nawo abalulekile: ukujula kwekesi elingu-3 mm kuqinisekisa ukumelana nokugqokwa ngaphandle kwengozi yokuphuka kwe-brittle ngesikhathi sokufakwa kwe-welding ground clamp.
Izindleko Ezifihliwe Zezinhlelo Zokukhweza "Zomhlaba wonke".
Amanye amathebula akhangisa “ukuhambisana kwe-modular” kodwa ngomkhumbi ofakwe imicu engu-M8 ehlukaniswe ngo-100 mm. Lokho kusebenza kahle—kuze kube yilapho udinga ukulungisa i-hydraulic manifold flange engu-47 mm-diameter edinga izikhungo zamabhawodi angu-60 mm. Ukuvumelana nezimo kwangempela kusho amaphethini egridi alungisekayo: 50 mm wamathuluzi avamile, 25 mm wama-micro-weldments, kanye nezimbobo zedowel ezinembayo ezingu-12.7 mm zokubhaliswa kwejigi okuphindaphindwayo. E-Botou Haijun Metal Products Co., Ltd., itafula ngalinye lisebenzisa i-geometry enezingqimba ezimbili ze-T-slot—izikhala eziphezulu zamukela izinsimbi ezivamile ezingu-10 mm; izikhala ezihlehlisiwe ezijulile zikhiya izikhonkwane zokuthola ngokwezifiso ezinokuphinda ±0.02 mm. Awekho ama-adaptha. Awekho ama-shims. Akukho ukuqagela.
Ukuphathwa Kwe-Thermal Kwangempela Komhlaba Akuxoxiswana
I-Welding ikhiqiza ama-spikes okushisa asendaweni angaphezu kuka-1,200°C. Ithebula elingenakho ukuphathwa kwe-thermal mass liphenduka ngokushesha kunokuba ungasho ukuthi "ukulungiswa kokuhlanekezela." Isixazululo sethu? Ipuleti eliwugqinsi elingu-32 mm elinezimbambo zangaphakathi eziphindaphinda inertia eshisayo ngenkathi yehlisa isisindo ngo-17% uma iqhathaniswa nepuleti eliqinile. Ubambo ngalunye lusebenza njengesitsha sokushisa, esihambisa amandla kude nendawo yokusebenza. Siqinisekisa lokhu sisebenzisa i-infrared thermography: izinga lokushisa elingaphezulu lihlala lingaphansi kuka-18°C ngemva kokudlula kahlanu okulandelanayo okungu-300-amp GMAW ocezwini lokuhlola lwensimbi ye-carbon engu-10 mm. Qhathanisa lokho namathebula esincintisana nawo abonisa ama-spikes angu-42°C—kanye nokukhothama okulandelayo okungu-0.23 mm kukalwa emgqeni omaphakathi.
Akukho ukuvumelana okufihliwe: Wonke amathebula asebenzisa i-ASTM A572 Gr. Insimbi engu-50—hhayi amamaki “alinganayo” anamandla esivuno angaqinisekisiwe Akukho umehluko wenqwaba: Ipuleti ngalinye lihlolwa nge-ultrasonic ukuze lifakwe ngaphansi komhlaba ngaphambi komshini Ayikho i-drift yokulinganisa: Ukufana kwe-T-slot okubanjwe ku-±0.05 mm/m ubude obugcwele, kuqinisekiswe nge-laser interferometer Kwenzekani Uma Weqa Ukubuyekezwa Kobunjiniyela
I-OEM eyodwa yezolimo yaseNyakatho Melika yayala amathebula angu-12 ngokusekelwe kuphela emidwebeni ye-CAD—akukho mpendulo ye-DFM eceliwe. Idizayini yabo isebenzise izimbobo zokukhweza ezingu-6 mm epuleti eliwugqinsi elingu-25 mm. Ngesikhathi sokuhlolwa kwenkundla, i-clamping torque ibangele ukuxebuka kwentambo ku-37% wezinto ezilungisiwe. Ukulungisa? Idizayina kabusha ukujula kwembobo ibe ngu-18 mm ngemicu egoqiwe esikhundleni sezintambo ezisikiwe—ukwandisa amandla okukhipha ngo-210%. Kungakho sinikeza isibuyekezo samahhala sedizayini esekwe ku-CAD phakathi namahora angama-72. Hhayi "ukubonisana." Hhayi “iziphakamiso.” Ukuqinisekiswa kobukhulu obulinganisekayo ngokumelene namazinga e-ASME Y14.5 GD&T, okuhlanganisa nokuhlaziywa kwesitaki sesimo esibi kakhulu sokulungiswa kwamaphuzu amaningi.
A itafula lokwenziwa kwensimbi ithola inani layo hhayi ku-weld yokuqala-kodwa ku-12,000. Iyazibonakalisa uma i-shift yesithathu iqhuba uhlelo olufanayo ngaphandle kokulungiswa kabusha. Uma u-opharetha omusha efinyelela ukulingana okungu-±0.1 mm ngosuku lwakhe lokuqala. Uma umbiko wakho we-CMM ubonisa ukuthi akukho ukuchezuka kwethrendi ezinyangeni eziyisithupha. I-Botou Haijun Metal Products Co., Ltd. yakha lawa mathebula eDolobheni lase-Botou—inhliziyo yemboni yase-China esebenza ngamakhaza—lapho isiyalo se-metallurgical singesona inketho. Ithebula ngalinye lithunyelwa ngesitifiketi esiphelele sezinto ezibonakalayo, idatha yokuqinisekisa ye-CMM, kanye nenombolo yendawo yokushisa elandelekayo. Ngoba ukunemba akusona isici. Yisisekelo.
