Kuwotcherera popanda jig kapena fixture kuli ngati kusonkhanitsa mipando popanda buku la malangizo - zotheka, koma zowopsa, zosagwirizana, komanso zomwe sizingabwerezedwenso. Pakusakaniza kwakukulu, kutsika kwapakatikati-makamaka mabulaketi agalimoto, zolumikizira zaulimi, kapena nyumba zopangira zida zomangira—jig ndi fixture kuwotcherera sichosankha. Ndiwo msana wa kukhazikika kwa mawonekedwe, kubwereza kwa weld, ndi chitetezo cha ogwiritsa ntchito.
Tawona makasitomala ambiri akutumiza magawo ankhani yoyamba kuti angopeza kusanja bwino kwa 0.3 mm m'mabowo omangika pambuyo pa kupotoza kwa kutentha. Ena amakonzanso 18% yamisonkhano yowotcherera chifukwa chakusintha pang'ono panthawi ya MIG. Izi si "zovuta za ndondomeko." Iwo ali mipata yokhazikika. Ku Botou Haijun Metal Products Co., Ltd., timapanga, kutsimikizira, ndi kutumiza zowotcherera makonda osati monga zowonjezera-koma monga zowonjezera zophatikizika zama cell weld palokha.
Chifukwa Chake Zosintha Zapa-Shelf Zimalephereka Pansi Pazogulitsa Zenizeni
Standard modular fixturing amagwira ntchito ma prototypes. Koma ma jigs adziko lenileni amayenera kupulumuka mizunguliro ya 5,000+, kukana kukwera kwa spatter, kuyamwa kugwedezeka kuchokera ku nyali za robotic, ndikusunga ± 0.15 mm kubwereza nthawi zonse. Nthawi ina tidawunika wogulitsa wa Tier-2 yemwe mawonekedwe ake "apadziko lonse" adagwiritsa ntchito zingwe zodzaza masika. Pambuyo pa kuzungulira kwa 472, mphamvu yochepetsera idatsika ndi 33%. Kulowa kwa weld kumasiyanasiyana ndi 22%. Chifukwa chake? Palibe chiwongola dzanja chokulitsa matenthedwe muzinthu zoyambira mbale.
Zoona jig ndi fixture kuwotcherera zothetsera zimafuna chidziwitso chazitsulo-osati kungoyika makina. Zitsulo zoziziritsa zozizira zimapindika pansi pa kutentha komweko; zitsulo za aluminiyamu zimakula mofulumira kuposa zopangira zosapanga dzimbiri; ngakhale ma torque a bolt amakhudza kulondola kwa zisa. Mainjiniya athu amawerengera ma drift coefficients asanadule mbale yoyamba. Ndicho chifukwa chake pulogalamu iliyonse yomwe timapanga imaphatikizapo:
Zida zokhazikika za thermally (ASTM A572 Gr.50 kapena EN 10025 S355JR) Zikhomo zowumitsidwa zokhala ndi kulolerana kwa ± 0.01 mm m'mimba mwake Mphamvu yothirira imasinthidwa malinga ndi geometry yolumikizana-osati zokonda "zapamwamba/zapakatikati/zotsika". Zishango zodzipatulira za spatter zomwe zimakwera *popanda* kusokoneza ma angles ofikira ma tochi Zokonzera Zowotcherera Zikakhala Mbali Yanu ya DFM
Ena angatsutse kuti: “Tingowotcherera kaye, ndiyeno tingowotchera malowo.” Izi zimawonjezera mtengo, kuchedwa, ndi chiwopsezo chochepa. Ku Haijun, timayika malingaliro okonzekera kuwunika koyambirira kwa Design for Manufacturability. Ngati bulaketi yanu ili ndi mabowo atatu omangika motalikirana ndi 120 mm—ndipo imafuna zowotcherera 90° fillet pama flanges awiri oyandikana—tidzapereka chizindikiro kuti cholumikizira choyenera chipezeke pamalo athyathyathya akulu kwambiri *poyamba*, osati m'mphepete mwaling'ono kwambiri. Chifukwa chiyani? Chifukwa kukhudzana kwapamtunda kumachepetsa kupotoza pansi pa kutsekereza katundu mpaka 60% motsutsana ndi omwe ali m'mphepete okha.
Izi sizongoyerekeza. OEM imodzi yaulimi yaku Europe idachepetsa chiwongola dzanja chawo cha post-weld Machining kuchokera pa 82% mpaka 99.4% atatengera njira yathu yopangira zisa. Kukonzekera kwawo koyambirira kunagwiritsa ntchito zikhomo za dowel pazinthu zachiwiri. Yathu idakhazikika ku utali wopindika woyambira - womwe sukhudzidwa pang'ono ndi masika. Zotsatira zake? Kukonzanso pang'ono, kutsata kwa GD&T molimba, komanso kutalika kosasinthasintha kwa ma weld onse 14.
Momwe Timatsimikizira Magwiridwe a Fixture-Musanadule Chitsulo
Sitidalira FEA yokhazikika yokha. Chiwonetsero chilichonse chimakhala ndi magawo atatu ovomerezeka:
Kuyesa kuzungulira mock-up: Zowuma zokhala ndi magawo oyimira pa liwiro lathunthu lopanga - kuyeza mavalidwe a malo, kutopa kwapang'onopang'ono, ndikufikira kwa oyendetsa Kutsimikizira kukana kwa Spatter: Mphindi 15 za kuwotcherera kwa MIG pogwiritsa ntchito mawaya enieni a chakudya ndi kutchingira kusakanikirana kwa gasi-ndiyeno kuyang'ana kumamatira kwa spatter pamalo ovuta. Thermal zilowerere mayeso: Kugwirizira pa 85 ° C kwa maola a 2 kutengera momwe zinthu ziliri m'chilimwe-kuwunikanso malo onse ndi CMM Lamuloli likufotokoza chifukwa chomwe makasitomala athu amanenera kuti palibe zosagwirizana ndi ziro m'malipoti omaliza oyendera miyezi 27 yapitayi. Izi sizitanthauzanso kukonzanso modabwitsa mukamakweza mayunitsi 50 mpaka 2,000 pakupanga pamwezi.
Kuchokera ku Mapangidwe a Fixture to Full-Welded Assembly-One Integrated Workflow
Kuphatikiza koyima kumasintha chilichonse. Ku Haijun, gulu lomwelo lomwe limapanga zida zanu zowotcherera zimakonzanso makina osindikizira a CNC omwe amapanga gawolo, amasankha kalasi yopanda dzimbiri yokana dzimbiri, ndikutsimikizira mphamvu yomaliza ya weld pa ISO 15614-1. Palibe ma handoffs. Palibe kutaya zomasulira pakati pa madipatimenti. Pamene bulaketi yanu ikufuna kuwotcherera 3-mm fillet pa 0.8-mm aluminiyamu flange, mainjiniya athu amalumikizana mwachindunji ndi akatswiri athu owotcherera - chifukwa amagawana malo ogulitsira omwewo.
Umu ndi momwe timaperekera misonkhano yokulirapo yokhala ndi ma callout a GD&T omwe amakhala ± 0.2 mm-ngakhale pazigawo zokhala ndi zolumikizira 12+ ndi zolumikizira zosakanikirana. Palibe ma subcontractors akunja. Palibe kulolerana stack-mmwamba zodabwitsa. Zongolembedwa zowongolera, kuyambira koyilo yaiwisi kupita ku kutumiza kosungika.
Kwa opanga omwe amachitira jig ndi fixture kuwotcherera monga zomangamanga zauinjiniya-osati zida zotsika mtengo-kusiyana kumawonekera pakukolola koyamba, kulephera kwamunda, komanso kusunga makasitomala. Kulondola sikutheka mu dziwe la weld. Imatsekeredwa mkati arc isanamenye. Yambani ndi kukonza koyenera. Mangani kuchokera pamenepo.
