I-Welding table jigs ayizona izesekeli-ayiziphindaphinda ngempoqo. Esitolo sethu, sibone amaqembu esika isikhathi somjikelezo we-weld ngo-40% ngokushintshanisa izinsimbi ezijwayelekile ngenjongo eyakhelwe inhloso. welding table jigs. Iklayenti elilodwa lempahla yezolimo linciphise ukusetshenzwa kabusha kusuka ku-12% kuya ngaphansi kuka-2% ngemva kokusuka ekwakhiweni okwenziwa ngesandla kuya ku-jig-based fixturing ephindaphindwayo. Lokho akukona ukuthuthuka okukhuphukayo. Ukulawulwa kwe-dimensional okwenziwe ngokomzimba.
Kungani Ukulungisa "Okwanele" Kuhluleka Ngaphansi Komthwalo Wangempela
Abakhiqizi abaningi baqala ngezinsimbi zama-engeli, ama-C-clamps, nezisekelo zikazibuthe. Ziyasebenza—kuze kube yilapho kuhlanekezelwa ukushisa, kuze kube ingxenye yesithathu yokugijima kweziqephu ezingu-50 ishintsha u-0.3 mm, kuze kube yilapho ubakaki behluleka ukuhlola ukukhathala ngenxa yokuthi ukungena kwe-weld kuyahlukahluka kulo lonke iqoqo. Siyilinganisile: izingxenye ezingavikelekile zichezuka kufika ku-0.8 mm ngesikhathi sokushisela i-tack kuphela. Lokho kunyakaza okuncane kusakazeka kuma-flange angaqondile, izikhala zezimpande ezingaguquki, kanye nokugxila kwengcindezi akukho ukugaya ngemuva kokushisela okungalungisa.
Ukulungiswa kweqiniso kwenza izinto ezintathu ngesikhathi esisodwa: ukuthola, ukusekela, nokuvimbela. Ukuthola izikhonkwane hit datums—hhayi cishe imiphetho. Amaphedi asekelayo afana nengxenye yekhontayutha—hhayi amapuleti ensimbi ayisicaba. Amandla okuvimbela aphikisana nama-vectors anwebekayo okushisa—hhayi nje amandla adonsela phansi. Kungakho welding table jigs eyakhelwe kumathebula e-modular T-slot adlula ukusetha kwe-ad-hoc ngaso sonke isikhathi: aguqula ukuhlukahluka kube ukuphindaphinda.
Okune Okungaxoxiswana Ku-Jig Design (Kusekelwa Iminyaka engu-7 Yedatha Yenkundla)
Siqinisekisa yonke i-jig yangokwezifiso ngokumelene nalezi zindlela ezine—ngaphambi kokusika ipuleti lokuqala:
Isinxephezelo Sokushisa: Amapuleti ayisisekelo asebenzisa insimbi egoqelwe ebandayo engu-12-mm-hhayi u-6-mm—ngoba impahla ezacile ijika ngokushesha ngaphansi kokushisa kwe-arc. Sengeza izikhala zokusiza ngaphansi kwezindawo ezishisa kakhulu ukuze sivumele ukunwetshwa kwenzeke kude nezindawo. Layisha Indlela Yobuqotho: Yonke intambo iphoqa imizila ngokuqondile kuhlaka lwesakhiwo sethebula—hhayi ngama-adaptha astakiwe. I-clamp eyodwa ye-pneumatic engu-12-kN ilahlekelwa amandla asebenzayo angu-35% uma ifakwe kuma-spacers angu-10-mm amabili. Ukungaguquguquki kweDatum: Zonke izitholi eziyinhloko zibhekisela endizeni ephezulu efanayo. Ukuxuba indawo esekwe embotsheni kanye nasenqenqemeni engxenyeni eyodwa kubangela iphutha elikhulayo. Sisebenzisa "idatha eyinhloko eyodwa ku-eksisi ngayinye" kukho konke ukubuyekezwa kwe-DFM. Ukufinyeleleka Kwamathuluzi: Izimbobo zokufinyelela ezishiselwe zilinganiswe ukuze zilingane nezibhamu ze-MIG—hhayi nje “ezinkulu ngokwanele.” Sihlola ngama-engeli wethoshi wangempela: 30°, 45°, kanye no-60° ukusondela. Uma i-nozzle ishaya i-jig ku-45 °, imbobo iyakhula noma isuswe. Lena akuyona imibono yetiyetha. Amamodi okwehluleka esingene kuwo kuwo wonke ama-run okukhiqiza angu-1,200+—kusuka exhaphozini eningi kuya emiphumeleni yokuphela yerobhothi ye-aluminium.
Lapho Ama-Jigs Angaphandle Kweshalofu Ewa Kafushane (Futhi Okufanele Ukwenze Esikhundleni So)
Abanye bangase baphikise: “Kungani ungathengi ama-jig etafula okushisela ajwayelekile?” Ngoba izingxenye zangempela azivamile ukufanisa amaphrofayela ekhathalogi. Ikhasimende lake la-oda “amajigi okukhweza injini” amahlanu afanayo—kuphela ukuze lithole ukuthi izindlu zabo ze-cast-aluminium zinama-engeli asalungiswa ahluka ngo-±0.5° kuwo wonke amaqoqo. I-jig ibambe Ingxenye # 1 kahle. Izingxenye #2–#5 zidinga ukucwebezela, ukugiya kabusha, nokuhlanganisa isandla kokugcina.
Yilapho ukuhlanganiswa okuqondile kubaluleke khona. E-Botou Haijun Metal Products Co., Ltd., siyaklama, sifake isitembu, sigobe, futhi sishisele amajig endlini—abekho abathengisi bamathuluzi bangaphandle, akukho ma-handoffs. Lapho umhlinzeki wezimoto we-Tier-1 edinga amajigi ethreyi yebhethri ye-EV entsha, silethe ama-prototypes asebenzayo ezinsukwini ezingu-11: Imodeli ye-CAD → ipuleti lesisekelo esisikiwe nge-laser → izingalo zendawo ezigobile ze-CNC → ukuhlanganiswa okushiselwe → ukuqinisekiswa kwe-CMM. Akukho ukulinda ukusakazwa komshini. Akukho ukubekezelela isitaki esivela kubahlinzeki abaningi.
Amakhasimende ethu awawakhokheli "ama-jigs." Bayakhokha ukungaguquguquki kwengxenye yokuqala yesokudla-futhi lokho kwenzeka kuphela lapho ukulungisa kwenziwa njengengxenye yohlelo lokukhiqiza lwengxenye, hhayi ukuboshwa kamuva.
Ukwakha Ukwethenjwa, Ubukhulu Obunye Ngesikhathi
I-Welding table jigs idalula ubuthakathaka enqubweni yakho-ngokushesha. Uma izingxenye zakho zingatholakali ngokungaguquki, i-jig iyakuveza. Uma i-springback yakho yezinto ezibonakalayo ingamodeli, i-jig ibonisa igebe. Lokho kubeka izinto obala akukhululekile—kodwa kuyadingeka.
E-Botou Haijun Metal Products Co., Ltd., siphatha amaphrojekthi we-jig afana nokuthuthukiswa okuhlanganyelwe: ukubuyekezwa okwabiwe kwe-GD&T, imibiko yokuhlola egxiviziwe yawo wonke amaphinikhodi wendawo, ukuhlolwa kwesifutho sikasawoti ezindaweni zokubamba i-zinc-nickel. Asithumeli amajiki “aqediwe”—sithumela ukuphindaphindwa okubhaliwe. Konke ukuthunyelwa kufaka phakathi idatha ye-CMM ebonisa ukuchezuka okukhulu ezingxenyeni ezingu-20 ezilandelanayo. Hhayi ama-avareji. Akukona ukufundwa okuhle kakhulu. Okubi kakhulu, kulinganiswa.
I-weld enamandla kakhulu akuyona leyo enensimbi yokugcwalisa kakhulu. Yileso esibekwe lapho umklamo wawuhloselwe khona-njalo. welding table jigs yenza leyo nhloso ifezeke. Futhi uma ukulungisa kwakho kusebenza njengethuluzi elinembayo—hhayi isibambi-ndawo—uyayeka ukulwa nokuhlanekezela, iziqephu, neziliphu zeshejuli. Uqala ukuthumela ukuzethemba.
