Ua ʻike kēlā me kēia welder TIG i ka ʻoiaʻiʻo: hoʻomaka ka pololei ma mua o ka paʻi ʻana o ke arc. ʻO ka millimeter hoʻokahi o ka neʻe ʻana ma lalo o ka wela e hoʻololi i ka geometry, hoʻonāwaliwali i ka pono hui, a pepehi i ka hana hou ʻana - ʻoi aku hoʻi i nā hui kila kila a i ʻole alumini i hoʻohana ʻia i nā hydraulics mahiʻai a i ʻole nā paʻa sensor automotive. Ua ʻike mua mākou: ua ʻoki kahi mea kūʻai ma Wisconsin i nā pūʻulu bracket 47 ma hope o ka weld distortion warped i nā lua ma mua o ± 0.15 mm ka hoʻomanawanui. ʻO ke kumu kumu? ʻAʻole ke koho uea hoʻopihapiha a i ʻole ka hoʻoheheʻe ʻana o ka amperage - ʻo ia ka paʻa ʻole.
No ke aha i hāʻule ʻole ai nā paʻa "maikaʻi" ma lalo o nā kūlana TIG maoli
ʻO ka wiliwili TIG e koi i ka ʻoi aku ka nui o nā jigs kumu nui e haʻalele ʻole. ʻAʻole like me ka MIG a i ʻole ka wiliwili wahi, hoʻohana ʻo TIG i ka wela i hoʻopaʻa ʻia i loko o nā lōʻihi lōʻihi. ʻAʻole manaʻo ka hoʻonui wela—hiki ke ana ʻia i loko o 3 kekona ma 1.2-mm 304 stainless. Hoʻonui ʻia kahi mea paʻa me ka pāʻani 0.05 mm ma ke kikowaena clamping i ka hoʻololi ʻana o ka ʻāpana 0.3 mm ma ka hoʻopau weld. Ua hoʻāʻo mākou i ʻekolu mau mea paʻa "universal" TIG e kūʻē i kā mākou hoʻolālā ponoʻī me ka hoʻohana ʻana i kahi sensor displacement laser calibrated. ʻAʻole i pau i ka ISO 10893-12 nā paepae kūpaʻa wela ma mua o ke kolu. ʻAʻole ke kumu kūʻai - ua hoʻohana hewa ʻia ka physics.
Loaʻa nā ʻano hana hemahema o ka honua maoli:
ʻO ka micro-deformation i hoʻopili ʻia: ʻO nā ʻāwae i hoʻopiha ʻia i ka pūnāwai i hoʻoheheʻe ʻia i nā ʻaoʻao alumini palupalu, e hana ana i nā ʻili datum hoʻopunipuni Ka neʻe wela ma nā papa kumu: Hoʻonui wikiwiki ʻia nā kumu kila māmā ma mua o nā ʻāpana 6061-T6, wāwahi i ka alignment waena waena Hoʻopili haʻalulu: Kani nā mea paʻa paʻa lahilahi ma 120–180 Hz—ke alapine like me ka TIG hoʻomaka i nā puʻupuʻu kiʻekiʻe—e hoʻoulu ana i ka ʻauwana arc. He aha ka hana maoli: ʻEhā mau mea kūʻai ʻole no ka hoʻoponopono pololei ʻana o TIG
Ma muli o 12 mau makahiki o ke kākoʻo ʻana i nā OEM mahiʻai ʻo Tier-1 a me nā mea hana aelike lāʻau lapaʻau, ua kūkulu mākou i nā mea paʻa e pili ana i ʻehā mau koi paʻakikī - ʻaʻole nā hiʻohiʻona, akā nā palena:
Koefficient thermal i kūlike i nā mea waiwai: Hoʻohana nā papa kumu i ka stainless 430 i ka wā e paʻa ai nā ʻāpana kuhili; 6061-T6 kumu alumini no nā hui alumini. ʻAʻohe hoʻopaʻapaʻa kila māmā. ʻAʻohe pāʻani kinematic loaʻa: E pili ana i ekolu mau kiko me na pine dowel paakiki (HRC 60) a me na poloka V lepo—aole i hoonoho i na wili a i ole na pani hiki ke hoololiia. Nā ala hoʻoheheʻe wela i mālama ʻia: Copper-alloy heat sink i hoʻohui pono ʻia ma lalo o nā ʻāpana weld, i helu ʻia no 200+ amps hana mau me ka ʻole o ka warping. ʻO ka hoʻololi ʻana i ka ikaika hoʻopili modular: Hāʻawi nā mea hoʻopili pneumatic i 1,200–2,800 N hiki ke hoʻopaʻa ʻia—ana ʻia i kēlā me kēia pōʻaiapuni ma o nā keena ukana i hoʻokomo ʻia, ʻaʻole i manaʻo ʻia mai nā ana kaomi ea. ʻAʻole mākou e kūʻai aku i ka "TIG welding fixture" ma ke ʻano he ʻano maʻamau. ʻenehana mākou pili-pili nā ʻōnaehana—no ka laʻana, he 14-kūlana rotary fixture no nā hui flange exhaust e mālama ana i ka ± 0.08 mm concentricity ma waena o 22 weld pass, a i ʻole kahi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i kōkua ʻia i nā pahu pahu pahu 0.8-mm kahi e hoʻopōʻino ai nā pipili magnetic i nā ala o kēia manawa.
Ma waho aʻe o ka Fixture: Pehea e wehewehe ai ka hoʻohui ʻana i ka hiki ke hana hou
ʻAʻole hiki ke hoʻopaʻa ʻia inā ʻoki ʻia mai ke kaʻina hana. Hoʻokomo mākou i nā puka puka manaʻo manawa maoli: nā thermocouple i hoʻohui ʻia e nānā i ka piʻi ʻana o ka wela o ka pā kumu; hōʻoia nā kānana kānana i ka pohō o ka ikaika o ka puʻupuʻu i nā pōʻai weld lōʻihi; a me nā mea ʻike maka e hōʻoia i ka loaʻa ʻana o kekahi hapa ma mua o ka hoʻomaka ʻana o ke arc. Hāʻawi kēia ʻikepili i kā mākou ʻōnaehana MES papa hale kūʻai - no laila ke hōʻike ʻia kahi pūʻulu he 0.02 mm awelika hoʻololi ʻana ma waena o 50 mau ʻāpana, ʻimi nā mea ʻenekinia iā ia i ka haʻahaʻa ambient e pili ana i ka hoʻokumu ʻana o ka alumini oxide-ʻaʻole ka hewa o ka mea hana.
Hoʻopaʻapaʻa paha kekahi he lohi loa ka hoʻoponopono maʻamau no nā hana haʻahaʻa. Akā ke hōʻike nei kā mākou mea kūʻai aku he 63% ʻoi aku ka wikiwiki o ka ʻae ʻana i ka ʻatikala mua inā loaʻa nā mea paʻa i nā mea ʻimi DFM-hōʻoia a me nā puka makani weld. No ke aha mai? No ka mea, ua lilo ka mea hoʻopili i ka prototype kino mua - e hōʻike ana i nā pilikia hoʻopilikia i nalo nā kumu hoʻohālike CAD. Ua ʻoki kekahi mea hoʻolako automation German i kā lākou hōʻoia hoʻolālā-i-weld mai 11 mau lā a i 36 mau hola me ka hoʻohana ʻana i kā mākou lawelawe prototyping hoʻonohonoho ponoʻī.
Ke koho ʻana i kāu hoa: E nānā ma mua o ka Catalog
Inā hāʻawi kāu mea hoʻolako i nā kumu hoʻohālike "TIG welding fixture" wale nō me ka ʻole o ka hōʻike loiloi wela a i ʻole ka palapala hōʻoia waiwai, ke kūʻai nei ʻoe i ka pilikia - ʻaʻole hiki ke hana hou. E noi no:
CTE (Coefficient of Thermal Expansion) palapala hoʻohālikelike ma waena o ke kahua paʻa a me kāu pani Nā palapala hōʻoia calibration no nā mea naʻau i hoʻopili ʻia (ʻaʻole wale ka CMM i hoʻohana ʻia no ka nānā hope ʻana) ʻO ka hōʻoia o ka hōʻoia i loko o ke kaʻina hana—e like me ka torque traceability logs no kēlā me kēia wahi pipili ma kēlā me kēia ʻāpana i hoʻouna ʻia. Hoʻokumu ʻo Botou Haijun Metal Products Co., Ltd. i kēia mau ʻōnaehana no ka mea hana mākou i nā ʻāpana a lākou e paʻa ai. ʻO kā mākou mea hoʻokō ISO ma ke kūlanakauhale ʻo Botou e holo like me nā laina kuʻikuʻi, kulou, a me nā laina wili—no laila noho nā mea ʻenekinia ma ka ʻaoʻao o nā welders hana i kēlā me kēia lā. ʻIke lākou i ke kūkulu ʻana o ka spatter ma nā pine locator. Manaʻo lākou i ka neʻe ʻana o ka vibration ma o ka papa hana. Hoʻohālikelike kēlā ʻike ola i kēlā me kēia mea hana welding tig a mākou e hāʻawi ai.
ʻAʻole i loaʻa ka repeatability me nā ʻae ʻoi aku ka paʻa wale. Kūkulu ʻia ia i ka wā e hoʻohālikelike ai ke ʻano wela, ka ʻepekema waiwai, a me ke kahe hana kanaka - e hoʻomaka ana me ka mea e paʻa ai ka ʻāpana. No nā welds TIG kūpono e kū ana i nā kelepona aerospace-grade GD&T a i ʻole nā koi PPAP automotive, ʻaʻole ia he mea kōkua. ʻO ia ka weld pass mua.
