ʻIke piha i nā kaʻina hana no ka hoʻopaʻa ʻana i ka ikehu Spot welder: lele hana

Hoʻolauna

I ka welding o hou ikehu kaʻa pila pila, kaWelder wahi hoʻopaʻa ikehume nā hemispherical projections e hoʻonui i ka ikaika weld e 40%; ua lanakila 'o ka 'oihana koa i ka wiliwili 'ole-spatter o nā-mea huila titanium i pa 'ia me ka paia ma o ka -ho'olālā ho'olālā kūikawā. Hōʻike kēia mau hihia i ke ʻano o ka projection o a Welder wahi hoʻopaʻa ikehuʻAʻole ia he hoʻolālā geometric maʻalahi, akā he ʻenehana pololei e hoʻohuihooponopono kahua o keia manawa, kaulike thermodynamic, amea rheology. Ma ke ʻano he kumu nui e hoʻoholo ai i ka maikaʻi o ka welding, pili pololei ke ʻano o ka projection i ka pono o ka nānā ʻana i ka ikehu (hiki ma luna o 92%) a me ka paʻa o ka weld nugget. Hoʻopili pū ʻia kēia ʻatikala i nā hiʻohiʻona kaʻina hana a me nā noi ʻenehana o ʻehā ʻano projection mainstream no ka Capacitor Discharge Spot Welders.

I. Kumu Kuleana: Pehea e pili ai ke kinona o ke ano i ka maikai wiliwili

• ʻO kaWelder wahi hoʻopaʻa ikehuʻike i ka hoʻokuʻu ʻana i ka ikehu kuhikuhi ma o ke kuhi ʻana ma ka piko electrode, a ʻo kona ʻano hoʻolālā pono e hoʻokō i ʻekolu pahuhopu:
• ʻO ka mana hoʻopaʻapaʻa o kēia manawa: E hoʻonui i ka hāʻawi ʻana i kēia manawa a pale i nā hopena lihi (hewa<±5%)
• Hoʻololi hoʻokomo wela: Hoʻokumu ʻia ka weld nugget a me ka laulā o ka wela -kahi i hoʻopilikia ʻia (HAZ).
• ʻO ka maikaʻi o ka lawe ʻana i ke kaomi: E hōʻoia i ka hoʻoili like ʻana o ke kaomi electrode (fluctuation<±3%)

Nā ʻāpana koʻikoʻi no ka hoʻolālā kino:

II. Nā ʻano Projection Mainstream a me nā ʻano ʻenehana

1. Hemispherical Projection (Dome Type)

• Nā hiʻohiʻona hale:

ʻO ka radius pōʻaiapuni R=0.8-2.5mm

Koko pili =90 degere ±5 degere

Hoʻopau maka chamfer 0.1-0.3mm

• Nā pōmaikaʻi ʻenehana:

'Oko'a ki'eki'e loa<15%)

He kūpono no ka hoʻoheheʻe ʻia ʻana o nā pā he nui (a hiki i ka 8 papa)

Longer electrode life (>500,000 pōʻaiapuni)

Nā noi ʻenehana:

Welding of copper-aluminum tabs for power batteries (yield >99.95%)

ʻO ka pilina o nā pā kila galvanized no nā mea hoʻopili hale

2. Kuhikuhi Cone i ʻoki ʻia

• Nā hiʻohiʻona hale:

ʻO ka huina cone θ=60 degere -90 degere

ʻO ke anawaena maka hope D=1.0-3.0mm

ʻOka ʻaoʻao paia Ra<0.4μm

• Nā holomua ʻenehana:

Ua hoʻonui ʻia ka pono o ka ikehu i ka 95%

Ua hōʻemi ʻia ka ʻāpana wela-e 30%

Kāohi ʻia ka nui o ka spatter<0.05%

• Nā hiʻohiʻona maʻamau:

ʻO ke kuʻi ʻana o nā pā hao titanium lahilahi i ka aerospace (ka mānoanoa 0.3mm)

Hoʻohui i nā mea like ʻole no nā implants lapaʻau

3. Papahana Papa

• Hoʻolālā i nā mea nui:

Hoʻopau i ka palahalaha maka<0.01mm

ʻO ka waihona lihi R=0.05-0.2mm

ʻO ka mānoanoa o ka uhi uhi 5-10μm

• Waiwai kumu:

ʻOi aku ka maikaʻi o ka hāʻawi like ʻana i ke kaomi (fluctuation<±1.5%)

He kūpono no nā mea kiʻekiʻe-oolea (HRC ʻoi aʻe ma mua a i ʻole like me 40)

Ua hoʻonui ʻia ka palahalaha welded e 50%

• Nā hihia noi:

ʻO ka wiliwili ʻana o ke kila ikaika -kiʻekiʻe no nā mea kaʻa kaʻa

ʻO ka hoʻopili ʻana i nā pahu wela alumini alumini no nā kahua kumu 5G

4. Kūlana -Shaped Projection

• Hoʻolālā hou:

He nui-ʻanuʻu (2-4 pae o ka ʻokoʻa kiʻekiʻe)

ʻO ke ʻano geometric asymmetric

ʻAno mānoanoa -microove (0.02-0.1mm ka hohonu)

• Nā holomua ʻenehana:

Hiki i ka 99% ka pololei o ka hoʻohālikelike impedance.

Ua hoʻonui ʻia ka nui o ka waiwai e 40%

Ua hoʻonui ka wikiwiki o ka welding i 120 mau kiko i kēlā me kēia minuke

• Nā noi kūikawā:

ʻO ke kuʻi pololei ʻana o nā hinges no nā kelepona hiki ke pelu

Hoʻohui ʻia o nā pipeline wahie satellite ma nā wahi ʻawaʻawa

III. ʻO ke ʻano koho ʻana i ke ʻano o ke ʻano: ʻElima Manaʻo Hoʻoholo

1. Ke Ana Hoʻohālike Pono Mea Pono

​

​

2. Mānoanoa Kūlike Kūlike

• ʻO ke kiʻekiʻe kiʻekiʻe kiʻekiʻe H=0.2×(t1 + t2) + 0.1mm​
• (t1, t{1}} mānoanoa o nā papa luna a lalo, ʻāpana: mm)​
• Laʻana hoʻohana i kahi ʻoihana ikehu hou:
• I ka wiliwili ana i 2mm + 1.5mm na papa alumini alumini, ua hoohanaia kekahi kuhi cone i okiia me H=0.8mm, a ua hiki ke anawaena weld nugget i 5.2mm (100% compliance rate).

IV. ʻOki-Ka Hoʻomohala Kūlana

1. ʻenehana hoʻololi naʻauao

• Hiki ke hoʻololi i ka manaʻo: Hoʻohālikelike ʻokoʻa i ka curvature projection e like me ka mānoanoa waiwai (manawa pane<0.1s)
• Ua hoʻomohala kekahi mea hana mea hana Kelemania i kahi electrode deformable:
• Kākoʻo i ka hoʻololi pūnaewele o 6 mau ʻano
• Ua hoʻonui ʻia ka maikaʻi o ka hoʻololi ʻana e 80%

2. Microstructure Optimization

• ʻenehana kikokikona ʻili:
• ʻO ka hoʻomaʻamaʻa ʻana i ka laser micromachining o ka nano{0}}mea hoʻonui (Ra{1}}μm ʻona)
• E ho'ēmi i ka hoʻopaʻapaʻa pili ma 15%
• E hoʻonui i ke ola electrode i 3 mau manawa

3. Hoʻolālā Kuleana Hui

• Electrode material gradient:
• Tungsten-pahu keleawe + uhi daimana (50μm mānoanoa)
• Ua hoʻonui ʻia ka -maha kiʻekiʻe i ka 800 degere
• ʻOi aku ke ola o ka electrode no ka wiliwili ʻana i ke kila ikaika -kiʻekiʻe ma mua o 800,000 pōʻaiapuni.

Ka hopena

Ua hōʻemi kekahi ʻoihana pākaukau mana alakaʻi i ka nui o ka spatter welding tab mai 0.5% a i 0.02% ma ka hoʻokomo ʻana i kahiWelder wahi hoʻopaʻa ikehume nā kuhi -kūikawā, e mālama ana ma luna o 5 miliona yuan no ka poho waiwai makahiki; Ua hoʻokō maikaʻi ʻia kahi ʻoihana hana aerospace i ka pilina hilinaʻi o 0.15mm titanium foil ma o ka hoʻolālā projection multi{3}}step, e paipai ana i ka hōʻemi kaumaha o nā satelite he 15%. Hōʻoia kēia mau hana e hiki i ka hoʻolālā ʻano projection pololei ke hoʻokō i ka hoʻomaikaʻi qualitative i ka maikaʻi wili o kahi Capacitor Discharge Spot Welder. Me ka hoʻohui pū ʻana o nā algorithms optimization topology a me ka ʻenehana hana hoʻohui, e loaʻa i nā hanana projection e hiki mai ana ʻekolu holomua: "deformation adaptive", "microstructure controllable", a me "functional gradient distribution", e hoʻokuʻu mau ana i ke kaʻina hana o ka hana kiʻekiʻe -hope.
