Pressure Welding The Efficiency Leader in Mass Production

Kuwotcherera kokakamiza kumatenga "kukakamiza" ngati njira yolumikizirana yoyambira, yosafuna (kapena pang'ono) zodzaza. Imakhala ndi liwiro lowotcherera mwachangu komanso mtengo wotsika, ndikupangitsa kuti ikhale yoyenera kulumikiza mbale zopyapyala ndi mawaya. Amagwiritsidwa ntchito kwambiri m'magawo monga kupanga magalimoto, kupanga zida zapanyumba, komanso kuyika zida zamagetsi.

(I) Resistance Welding: The "Core Technology" in Automotive Manufacturing

Resistance kuwotcherera amagwiritsa ntchito mfundo ya "kukhudzana kukana kutentha." Imalepheretsa zida zogwirira ntchito ndikudutsa mafunde akuluakulu, kutulutsa kutentha kwambiri komweko kuti kusungunuke (kapena kupunduka) zitsulozo. Pambuyo kuzirala, mawanga a weld amapangidwa. Iwo anawagawa mu mitundu itatu: malo kuwotcherera, msoko kuwotcherera, ndi kusonyeza kuwotcherera, amene malo kuwotcherera ndi "mphamvu yaikulu" mu kuwotcherera thupi galimoto.

1. Malo kuwotcherera: The "Dot masanjidwewo" Tekinoloje Yothandiza Kujowina

Mfundo yofunikira: Maelekitirodi awiri amathina mbale zoonda ndikudutsa mphamvu yayikulu ya 1000-10,000A. Kusagwirizana pakati pa maelekitirodi ndi mbale zopyapyala kumatulutsa kutentha, zomwe zimapangitsa kuti zitsulo zisungunuke zipange "fusion core." Pambuyo pozimitsa, kukakamiza kumasungidwa mpaka kuzizirira kuti apange malo ozungulira. Kupanga ma welds angapo kumathandizira kulumikizana m'malo akulu.

Zopangira:

•    Kusankha kwa Electrode:Gwiritsani ntchito ma elekitirodi a copper-chromium alloy powotcherera zitsulo za carbon low ndi copper-zirconium alloy electrodes powotcherera mapepala achitsulo. Sungani nsonga ya elekitirodi kukhala yosalala ndikuyiyikanso pakapita nthawi mutatha kuvala (m'mimba mwake nthawi zambiri imakhala 2-3 kuposa makulidwe a mbale).

•    Parameter Control:Mtheradi zimagwirizana ndi kuwotcherera nthawi (0.1-0.5 masekondi), panopa (kusintha malinga ndi makulidwe mbale; mwachitsanzo, 3000-4000A kwa 2mm wandiweyani mbale zitsulo), ndi kukakamiza (onetsetsani zolimba kukhudzana maelekitirodi ndi workpieces kupewa kwambiri kukhudzana kukana) kupewa soldering ozizira kapena kuwotcha-kudzera.

•    Kuwunika Ubwino:Mawanga a weld ayenera kukhala opanda ming'alu ndi spatter. Pakuyezetsa kolimba ndi makina oyesera olimba, "kung'ambika kwachitsulo" m'malo mwa "kutchingira mawanga" kuyenera kuchitika kuti zitsimikizire mphamvu zowotcherera.

2. Seam Welding: The "Continuous Defense Line" ya Zosindikizidwa Zosindikizidwa

Kuwotcherera kwa msoko ndi kofanana ndi kuwotcherera, koma maelekitirodi amasinthidwa ndi zodzigudubuza zamkuwa. Zodzigudubuza zimazungulira ndikudutsa pulsed current kuti apange weld mosalekeza. Ndioyenera kuwotcherera zomata zomata monga matanki amafuta agalimoto, zoyatsira zotenthetsera madzi, ndi zolumikizira mapaipi. Mukamagwira ntchito, wongolerani kuthamanga kwa wodzigudubuza ndi liwiro lozungulira kuti muwonetsetse kuti kuwotcherera kosalekeza, kopanda kutayikira. Mukawotcherera mapepala achitsulo, yeretsani nthaka yosanjikiza ya zinki pafupipafupi kuti mupewe kukana kukhudzana.

(II) Kuwotcherera Kukantha: "Njira Yamphamvu Kwambiri" ya Magawo Ofanana ndi Shaft

Kuwotchera kwa Friction kumakwaniritsa kujowina kudzera mu "kutentha kozungulira kothamanga kwambiri." Imangiriza magawo awiri a cylindrical (monga ma shaft ndi ndodo), imodzi imazungulira mwachangu (1000-5000r / min). Kutentha kopangidwa ndi kukangana kumabweretsa malo okhudzana ndi pulasitiki. Pambuyo poyimitsa kasinthasintha, kukakamiza kwakukulu kumagwiritsidwa ntchito kuti apange weld wamphamvu.

•    Zabwino Kwambiri:Mkulu kuwotcherera mphamvu (kuwotcherera mphamvu apamwamba kuposa zitsulo m'munsi), palibe porosity kapena slag kuphatikiza, ndi kufulumira kuwotcherera liwiro (pamodzi kuwotcherera nthawi

•    Zopangira:Yang'anirani liwiro lozungulira ndi kuthamanga kwa kukangana kuti muwonetsetse kutentha kofanana pamalo olumikizana (peŵani kutenthedwa kwanuko); pamene kuwotcherera zipangizo zosiyana (monga zitsulo ndi mkuwa), sinthani liwiro lozungulira ndi kuthamanga kuti muteteze ming'alu yomwe imayambitsidwa ndi kusiyana kwa ma coefficients owonjezera kutentha.
