Izinto zokushisela ezijwayelekile ziletha ukunemba okuphindaphindwayo kanye noshintsho olusheshayo—ikakhulukazi uma isitolo sakho siphethe imindeni eminingi, ukugijima kwenqwaba okuphansi kuya kokumaphakathi, noma ukuphindaphindwa kobunjiniyela okuvamile. E-Botou Haijun Metal Products Co., Ltd., siwathumele kuwo wonke amaphrojekthi okwenziwa angu-127 kusukela ngo-2021. Kuzo zonke izimo, isikhathi sokusetha sehle ngo-63% ngokwesilinganiso. Ukwehluka kobukhulu emibuthanweni yokushisela kuqiniswe ukusuka ku-±1.8 mm ukuya ngaphansi kuka-±0.4 mm. Futhi yebo-silinganise lokho ngama-CMM alinganiselwe, hhayi izilinganiso.
Kungani "i-modular" ingeyona nje i-hype yokuthengisa-iwukuphindaphinda okusekelwa yi-physics
Amajigi ashiselwe endabuko akhiya ijiyomethri ibe uhlaka lwensimbi olulodwa. Shintsha indawo yomgodi owodwa? Ufake umshini, ushise kabusha, uphinde ushise-uphinde ulinde izinsuku ezintathu ukuze uthole ukukhululeka kwengcindezi. Izinto zokushisela ezijwayelekile zisebenzisa amapuleti ayisisekelo ajwayelekile, izikhombi, izinsimbi, nezigaxa ze-kinematic—konke kuqiniswe ku-HRC 58–62, konke okulandelekayo kwe-ISO 9001. Siwakhweza ngezikhonkwane zedowel kanye nezinsimbi ezilawulwa yitorque, hhayi ama-tack weld. Lokho kusho ukuhlanekezela kwe-zero ngesikhathi somhlangano. Futhi kusho ukushintsha iphinikhodi yendawo engu-32-mm yenguqulo engu-25-mm kuthatha amasekhondi angu-47—hhayi amahora angu-4.5.
Kodwa nakhu abahlinzeki abaningi abangeke bakutshele kona: i-modularity isebenza kuphela uma izingxenye eziyisisekelo zesistimu zabelana ngesakhiwo sedatha evamile. Sisebenzisa igridi engu-100 mm × 100 mm ene-±0.01 mm yokubekezelela indawo kuyo yonke indawo yepuleti. Yonke imbobo, imbobo, kanye ne-T-slot iqondana naleyo grid. Cha “kusondele ngokwanele.” Akukho ukuthuthukisa inkambu. Uma amakhasimende esithumela amafayela we-STEP anama-callout we-GD&T, siqinisekisa ukubekwa kwendawo kuleyo grid ngaphambi kokusika noma iyiphi insimbi.
Umphumela womhlaba wangempela? Iklayenti elilodwa lemishini yezolimo linciphise isikhathi sokuhlolwa kwesihloko sokuqala sisuka emahoreni ayi-11 saya kumizuzu engama-92. I-jig yabo yangaphambili ibidinga ukucwayiza okwenziwa ngamaphuzu ayisithupha. Inguqulo yethu ye-modular isebenzise ama-v-block amathathu azibekela maphakathi nendawo kanye nezinsimbi ezimbili zokuguqula umoya womoya—zombili zilinganiswe kusengaphambili ukuze ziphindeke zibe ngu-0.005 mm.
Amaphutha amathathu abulala i-ROI ngaphambi kwe-weld yokuqala
Amanye amaqembu aphatha ama-modular fixtures njengamasethi e-Lego—ukuquleka ndawonye, ukubophela phansi, ukuqala ukushisela. Lokho kwehluleka ngaso sonke isikhathi. Nakhu okuphukayo ngempela:
Iziba i-base plate flatness: I-warp engu-0.15 mm ngaphezu kuka-600 mm idala iphutha elikhulayo le-angular. Siqinisekisa ukucaba kwamapuleti angaphezulu kwegwadle ngaphambi kokuthunyelwa—hhayi ngezikhombisi zokudayela, kodwa ngama-laser interferometer. Ukuxuba brand: Akuwona wonke ama-T-slots “ajwayelekile” afana nokubekezelelwa kwe-ISO 2768-mK. Sihlanganisa kuphela izingxenye ezihlolwe ngokumelene nezikali zethu eziyinhloko. Ukuhambisana kwe-Cross-brand kubukeka kukuhle ephepheni-kuze kube yilapho i-weld pass ye-17 ishintsha ingxenye engu-0.3 mm ukusuka phakathi nendawo. Ukweqa ukuqondanisa kwe-DFM: I-fixture ingabamba ingxenye kahle—kodwa uma i-bend radii yengxenye noma izindawo zokufinyelela ze-weld zingqubuzana nokubekwa kwe-clamp, opharetha bazokhulula amabhawodi noma bengeze izikhala. Sisebenzisa amasheke e-DFM *ngaphambi kokuba* kuqale ukwakhiwa kwesakhiwo. Uma ijoyinti lokushisela lihlala ngo-8 mm ukusuka onqenqemeni lwe-flange, siyalimaka—futhi siphakamise ukukhushulwa kwerediyasi engu-0.5 mm ukuze kusule umhlathi we-clamp. Sibone izitolo zisebenzisa u-$18,000 ku-hardware esetshenziswayo—bese zilahlekelwa u-$22,000 emfucumfucwini phakathi nezinyanga ezintathu ngoba zeqa lezo zinyathelo. I-modularity ayikuthetheleli ukuhlela okubi. Kuyayikhulisa.
I-Botou Haijun yakha kanjani izinto ezisindayo ezitezi zesitolo sangempela
Asithengisi izingxenye zekhathalogi. Sakha izinto zokushisela ze-modular njengamasistimu angaphansi anjiniyela—ngokuqina okufanayo esikusebenzisa kubakaki bezimoto abadonsa kanzima. Yonke imidlalo ihlanganisa:
I-stress-rexid EN-GJS-400-15 ductile iron base plate, eyenziwe ngomshini ngokusebenza okukodwa okuqhubekayo kumshini wethu wokugaya we-CNC gantry (akukho ukulungiswa kabusha) Izindawo ezenziwe ngensimbi eqinile ye-AISI 4140, enezindawo ezitholakala phansi kanye neziteshi zokupholisa ezididiyelwe zezinhlelo zokusebenza zomjikelezo ophezulu. Izinsimbi zomoya zikalelwe imijikelezo eyi-12,000 ubuncane—zihlolwe endlini ngamaseli omthwalo kanye nezinto zokubala zomjikelezo, hhayi amadatha emininingwane yomthengisi. Imibiko yokuhlola yobukhulu obugcwele: I-CMM ihlola wonke ama-datum abalulekile, ukuqinisekiswa kokuqina ngamaphuzu amahlanu ngendawo ngayinye, nokuqinisekiswa kwetorque kuso sonke isixhumi. Sithumela okuhleliwe ngamakhodi e-QR enziwe ngokwezifiso. Skena eyodwa, bese ukhipha umlando wayo ogcwele we-metrology—amalogi e-CMM, izitifiketi zokuphatha ukushisa, ngisho nokuphuma komshini endaweni yokuhlola ngayinye ye-QC. Awekho ama-PDF. Awekho amaketanga e-imeyili. Idatha esanda kuqinisekiswa.
Lokhu akubona ubunjiniyela obudlulele. Kuyindlela esigcina ngayo u-95.7% wokulethwa ngesikhathi kuwo wonke amazwekazi angu-4—ngisho nezicelo eziphuthumayo zamahora angu-72. Ngoba lapho i-fixture ifika, iyasebenza. Okokuqala. Zikhathi zonke.
Qala lapho inqubo yakho ihlala khona-hhayi lapho amakhathalogi aqala khona
Uma iphrojekthi yakho elandelayo ihlanganisa amashidi ensimbi anokubekezelela komthungo wokushisela okungu-±0.3 mm—noma uma ucaphuna ama-prototype anezibuyekezo ezintathu zedizayini ezilindelekile—izinto zokushisela eziyimodyuli azikhethi. Bayindlela yakho eshesha kakhulu yokukhiqiza okuzinzile. I-Botou Haijun Metal Products Co., Ltd. iklama futhi ikhiqize izinto ze-welding ze-modular endlini, usebenzisa indawo efanayo ethobela i-ISO ekhiqiza abakaki bakho abanezigxivizo kanye nezindawo ezivalekile. Awekho ama-handoffs. Abekho abathengisi bangaphandle. Iqembu elilodwa nje elingumnikazi wejiyomethri ukusuka kufayela le-CAD ukuya ku-weld yokugcina.
Siphendula imibuzo yobuchwepheshe phakathi kwamahora angu-48. Impendulo yobunjiniyela—okuhlanganisa imidwebo yomqondo wokulungisa nokubekezelelana—ihlala ebhokisini lokungenayo phakathi kwezinsuku ezintathu zokusebenza. Futhi uma ingxenye yakho ine-weld joint eduze nokugoba kwerediyasi eqinile? Sizokutshela—ngaphambi kokuthi usike kungenalutho lokuqala.
Ukuzinza kuqala ngokuma okubikezelwe. Ukunemba kuqala lapho ingxenye ithinta insimbi. Yingakho wonke izinto ze-welding ze-modular Uhlelo esilulethayo luphethe iwaranti yokusebenza yezinyanga ezingama-24—hhayi nje ngokumelene nokukhubazeka, kodwa ngokumelene nokwehluleka ukubamba ukubekezelela okushicilelwe ngaphansi kwezimo zokusebenza ezivamile.
