Wonke umshicileli uyalazi iqiniso: isisekelo esintekenteke sichitha ukunemba. Ithebula elisontekile lihlanekezela ukuhlanganisa. Uhlaka oluntekenteke lumunca amandla esikhundleni sokulubamba. Sibone izitolo zichitha amahora zisebenza kabusha izingxenye ngenxa yazo itafula lokusebenza welding ayikwazanga ukubekezelela ukushisa noma umthwalo. Lelo akulona iphutha lomsebenzisi—ukushayisana kwemishini.
Kungani "Umsebenzi Onzima" Kungewona nje I-Hype Yokuthengisa
Ukusebenzisa umsebenzi osindayo kwangempela kusho izinto ezilungiswayo ezingu-300+ kg eziboshelwe ku-torque egcwele, ukuphindaphinda amabhayisikili ashisayo ukusuka kumaphasi e-MIG ku-250A, futhi umthelela wansuku zonke osuka kuma-engeli wokugaya wehla phezulu. Amathebula amaningi ahluleka kwelinye lamaphoyinti amathathu: ukuqina kozimele, ukugcinwa kokucaba kwendawo, noma ubuqotho be-T-slot. Sihlole amamodeli ayisishiyagalombili ngapha nangapha endaweni yethu yokusebenzela yaseBotou—ukulinganisa ukuchezuka ngaphansi komthwalo omile ongu-1,200 kg, silandelela ukuchezuka kwendawo ngemva kwamahora angu-48 okulingisa imijikelezo yokushisela, futhi sabheka ukuguga kwe-T-slot ngemva kokufakwa kwe-clamp engu-1,500.
Abawinile babelane ngezici ezintathu: amafreyimu ensimbi ashiselwe—hhayi amabhawodi—asebenzisa ubuncane bodonga obungu-8 mm ubukhulu; insimbi ecijile ngomshini noma iziqongo zensimbi eziqinile ezino-≤0.15 mm/m zokubekezelela flatness; kanye nama-T-slots asikwe kumazinga e-ISO 2768-mK, awagxivizwa noma afakwe ngaphakathi. Iyunithi eyodwa ihlulekile evikini layo lokuqala: ingaphezulu le-aluminium liguquguquke ngo-0.8 mm ngaphansi kwamandla okucindezela kuphela. Enye ishubhu yefreyimu yensimbi ethambile esetshenzisiwe—egobile ngokubonakala ngemva kwamasonto amabili okusetshenziswa kokukhiqiza. Lawa akuwona amacala. Ziwukweqa okuvamile lapho abathengi bebeka kuqala intengo kunesayensi yezinto ezibonakalayo.
I-Botou Haijun Metal Products Co., Ltd. yakha yonke into itafula lokusebenza welding kulawo maphuzu okuhluleka abhekiwe. Kusukela ngo-2010, siye sahlinzeka ngamatafula ezitolo zokwenziwa kulo lonke elase-Russia, Turkey, ne-Southeast Asia—hhayi njengamathuluzi ajwayelekile, kodwa njengamasistimu okusebenza alinganiselwe. Imodeli yethu evamile ye-HD-2000 isebenzisa uhlaka lwensimbi yesakhiwo lwe-Q345B, i-CNC-machined 40 mm ugqinsi lwe-HT250 cast iron top, kanye ne-12 mm ejulile T-slots eno-20 mm pitch. Ibamba ukucaba okungu-±0.08 mm endaweni engu-2,000 × 1,000 mm—ngisho nangemva kwezinyanga eziyi-18 zokusebenza okusekelwe kushifti endaweni yokufaka amapayipi eduze kwaseKazan.
Ukwenziwa Okunembayo Kudinga Okungaphezu Kokucaba
I-flatness ibalulekile-kodwa kuphela uma indiza yakho eyinkomba ihlala izinzile ngesikhathi sokushisela. Ukunwetshwa kwe-thermal kunqamula ukuqondanisa ngokushesha kunokucindezeleka komshini. Abanye abasebenzisi bacabanga ukuthi itafula legwadle lixazulula lokhu. Akulungile. I-Granite ayikuphathi kahle ukushisa, idale izindawo ezishisayo ezisonta amajigi aseduze. Insimbi yanda ngokubikezelwa; I-iron cast idambisa ukudlidliza kangcono. Sikhethe i-HT250 nge-coefficient yayo engu-10.5 × 10⁻⁶/K—ivale ngokwanele kuya kuzinto zensimbi ezithambile ukuze kuncishiswe ukunyakaza okuhlukile ngesikhathi sokushisisa.
Kodwa ukukhetha kwezinto ezibonakalayo kuphela akwanele. Sengeza isici esifihliwe: isistimu yokukhweza yezendlalelo ezimbili. Ipuleti eliphezulu libhawuda kugridi yesibili yosekelo eqhelelene ngo-250 mm, yona ngokwayo encike ezinyaweni ezikwazi ukulungiseka ukuzihlukanisa. Lokhu kwehlisa ukuhlanekezela okushisayo phezulu kusuka kuhlaka oluyisisekelo. Empeleni, lokhu kusho ukuthi ingxenye eqondaniswe kokuthi 20°C ihlala ngaphakathi kokubekezelela okungu-0.12 mm kuzinga lokushisa elingaphezulu elingu-85°C—okuqinisekiswa ngezilinganiso ze-laser tracker phakathi nokuhlolwa kokushisela okubukhoma.
Abanye bangase baphikise ngokuthi amathebula e-modular anokufakwa okushintshekayo anikeza ukuguquguquka okwengeziwe. Kodwa-ke, okufakiwe ngakunye kunezela indiza engase ishelele. Silinganise ukudlala okunqwabelanayo kusistimu ye-modular edumile: 0.32 mm inani eliphelele lokuphuma ngemva kwezinguquko ezintathu zokufaka nemijikelezo emihlanu yokubopha. Idizayini yethu ye-fixed-top isusa lokho kuguquguquka ngokuphelele. Ukuvumelana nezimo kuvela ekuhlelweni kwezisekeli ezihlakaniphile—hhayi ukuyekethisa kusisekelo.
Lokho Abathengi Empeleni Okufanele Bakwazi Ngaphambi Koku-oda
Imibuzo emithathu inquma impumelelo—noma ukuzisola:
- Imuphi umsebenzi wakho omkhulu owodwa? Hhayi "okujwayelekile," kodwa okuphezulu. Engeza u-20% wemajini endaweni yokulungisa. Ubakaki omude ongu-1,500 mm udinga ubude obusebenzisekayo obungu-≥1,800 mm—hhayi nje ubude betafula, kodwa indawo ecacile ye-T-slot ngale kwezinsimbi.
- Ithini inqubo yakho yokushisela? Abasebenzisi be-TIG badinga ukucaba okuqinile (≤0.1 mm/m) kanye nezindawo ezingezona uzibuthe. Izitolo ze-MIG zibeka phambili ukunqanyulwa kokushisa nokujula kwe-T-slot kuma-clamp asindayo. Ukuhlanganiswa kokusika i-Plasma kufuna ukuqhubeka—amathebula ethu ahlanganisa amalugi e-copper braid angu-16 mm² emakhoneni amane.
- Uzoyiqinisa kanjani? Ukwehliswa phansi akuyona into yokuzikhethela kumatafula angaphezulu kwe-1,200 kg yomsebenzi. Sinikezela ngamakhithi ehange e-M12 alinganiselwe ngo-120 kN wokudonsa kukhonkolo we-C25—kodwa kuphela uma i-floor slab yakho ihlangabezana namandla okucindezela ezinsuku ezingama-28 ≥25 MPa. Sibone ukufakwa okuthathu kuhluleka ngenxa yokuthi osonkontileka beqe umbiko wokuhlola ophathekayo.
Ukufakwa kuthatha amahora angu-4-6 ngochwepheshe ababili. Ukubeka ileveli kudinga ileveli yomoya enembayo (ukuzwela okungu-0.02 mm/m) kanye ne-torque wrench emiswe ukuze ibe ngu-85 N·m kuwo wonke amabhawodi asuka kuzimele kuye phansi. Ukweqa ukulinganisa kuqeda iwaranti ye-flatness. Sifaka isitifiketi sokulinganisa esiqinisekisiwe esinawo wonke amayunithi—okulandeleka ngelebhu egunyazwe yi-CNAS No. L7291.
Ithebula Lakho Liyi-Weld Yokuqala Kuwo Wonke Umsebenzi
A itafula lokusebenza welding ayibambi izingxenye. Iphethe inhloso yobukhulu. Iphethe isithembiso sokuphindaphinda kuwo wonke amaqoqo, amashifu, nabaqhubi. Uma i-jig ihluleka, izindleko akuzona nje izinsimbi ezilahliwe-isikhathi sokulungiswa kabusha, ukuthunyelwa okubambezelekile, kanye nokwethenjwa kwamaklayenti.
I-Botou Haijun Metal Products Co., Ltd. iphatha wonke amatafula njengenkundla yebanga le-metrology. Hhayi ngoba singonjiniyela ngokweqile—kodwa ngoba ukwakheka komhlaba wangempela kusifundise ukuthi amakhefu, ashesha kangakanani, futhi ngani. Amathebula ethu awakuqedi ukuhlukahluka. Ziyiqukethe. Baguqula ukukhukhuleka okushisayo kube idatha ebikezelwayo. Baguqula ikhono lomsebenzisi libe okukhiphayo okungaguquki.
