M'mapaipi opangidwa ndi nthawi yayitali (Mtengo wa ERW), mawonetseredwe a ming'alu amaphatikizapo ming'alu yayitali, ming'alu yamtundu wanthawi ndi nthawi komanso ming'alu yapakatikati. Palinso mapaipi achitsulo omwe alibe ming'alu pamtunda pambuyo pa kuwotcherera, koma ming'alu idzawoneka pambuyo pokhazikika, kuwongola kapena kuyesa kuthamanga kwa madzi.

Zomwe zimayambitsa ming'alu

1. Kuipa kwa zipangizo

Popanga mipope yowotcherera, nthawi zambiri pamakhala ma burrs akulu komanso zovuta zambiri m'lifupi mwake.
Ngati burr ili kunja panthawi yowotcherera, n'zosavuta kupanga ming'alu yopitirira komanso yayitali.
M'lifupi mwazinthu zopangira ndi zazikulu kwambiri, dzenje la mpukutu limadzaza kwambiri, limapanga mawonekedwe a pichesi wonyezimira, zizindikiro zowotcherera zakunja ndi zazikulu, zowotcherera mkati ndizochepa kapena ayi, ndipo zimasweka pambuyo kuwongola.

2. M'mphepete ngodya olowa boma

Kulumikizana kwa ngodya m'mphepete mwa chubu chopanda kanthu ndi chinthu chodziwika bwino pakupanga machubu opangidwa ndi welded. Chitoliro chocheperako, m'pamenenso cholumikizira chapakona chimakhala cholimba.
Kusintha kosakwanira kwa mapangidwe ndikofunikira pamakona akona.
Mapangidwe osayenera a squeeze roller pass, fillet yayikulu yakunja ndi ngodya yokwera ya chopukutira ndi zinthu zofunika kwambiri zomwe zimakhudza mbali yolumikizirana.
Utali wozungulira umodzi sungathe kuthetsa mavuto olowa m'makona obwera chifukwa chosamangika bwino. Wonjezerani mphamvu yofinya, apo ayi chopukusira chofinyidwa chidzatha ndikukhala elliptical mu gawo lotsatira la kupanga, zomwe zidzakulitsa mkhalidwe wowotcherera wooneka ngati pichesi ndikuyambitsa kulumikizana kwakukulu.

Mgwirizano wa ngodya udzachititsa kuti zitsulo zambiri zituluke kuchokera kumtunda, kupanga njira yosungunuka yosungunuka. Panthawiyi, padzakhala zitsulo zambiri zowonongeka, msoko wowotcherera udzatenthedwa, ndipo ma burrs akunja adzakhala otentha, osakhazikika, aakulu komanso osavuta kukanda. Ngati kuthamanga kwa kuwotcherera sikuyendetsedwa bwino, "kuwotcherera kwabodza" kwa kuwotcherera kudzachitika mosalephera.

Mbali yakunja ya chodzigudubuza ndi yayikulu, kotero kuti chubu chopanda kanthu sichidzadzazidwa kwathunthu mu chodzigudubuza, ndipo m'mphepete mwa nyanja kukhudzana ndi kusintha kuchokera kufanana ndi "V" mawonekedwe, ndipo chodabwitsa kuti mkati kuwotcherera msoko si welded. .

Chofinyidwa chofinya chimavalidwa kwa nthawi yayitali, ndipo maziko oyambira amavala. Miyendo iwiriyi imapanga ngodya yokwera, zomwe zimapangitsa kuti pakhale mphamvu yofinya yosakwanira, ellipse yolunjika komanso kukhudzana kwambiri.

3. Kusankhidwa kosayenera kwa magawo a ndondomeko

The ndondomeko magawo a mkulu pafupipafupi welded chitoliro kupanga monga kuwotcherera liwiro (unit liwiro), kuwotcherera kutentha (mkulu pafupipafupi mphamvu), kuwotcherera panopa (mkulu pafupipafupi pafupipafupi), extrusion mphamvu (akupera chida kapangidwe ndi chuma), kutsegula ngodya (akupera ) ya chida Kupanga ndi zinthu, malo a coil induction), inductor (chinthu cha koyilo, mayendedwe okhotakhota, malo) ndi kukula ndi malo okana.

(1) Kuthamanga kwakukulu (kokhazikika ndi kosalekeza) mphamvu, kuthamanga kwa kuwotcherera, mphamvu yowotcherera extrusion ndi ngodya yotsegula ndizofunika kwambiri zomwe zimayenderana bwino, mwinamwake khalidwe la kuwotcherera lidzakhudzidwa.

① Ngati liwiro liri lokwera kwambiri kapena lotsika kwambiri, limapangitsa kuti kutentha kwapang'onopang'ono kusakhale kotentha komanso kutentha kwambiri, ndipo weld amasweka ataphwanyidwa.

②Pamene mphamvu yopondereza ili yosakwanira, zitsulo zam'mphepete zomwe zimayenera kutsekedwa sizingagwirizane kwathunthu, zonyansa zotsalira mu weld sizimatulutsidwa mosavuta, ndipo mphamvu imachepetsedwa.

Mphamvu ya extrusion ikakhala yayikulu kwambiri, mbali yachitsulo imachulukirachulukira, zotsalira zimatulutsidwa mosavuta, malo omwe amakhudzidwa ndi kutentha amakhala ocheperako, ndipo mawonekedwe awotcherera amakhala bwino. Komabe, ngati kupanikizika kuli kwakukulu, kumayambitsa zipsera zazikulu ndi kuphulika, zomwe zimapangitsa kuti oxide yosungunuka ndi gawo la pulasitiki lachitsulo litulutsidwe, ndipo weld adzakhala wochepa thupi pambuyo pokanda, potero kuchepetsa mphamvu ya weld.
Mphamvu yokwanira yotulutsa mphamvu ndizofunikira kwambiri kuti mutsimikizire mtundu wa kuwotcherera.

③Makona otsegulira ndi akulu kwambiri, omwe amachepetsa kuyandikira kwafupipafupi, kumawonjezera kutayika kwapano, komanso kumachepetsa kutentha kwa kuwotcherera. Ngati kuwotcherera pa liwiro choyambirira, ming'alu idzawoneka;

Ngati ngodya yotsegulira ndi yaying'ono kwambiri, kuwotcherera pakali pano kudzakhala kosakhazikika, ndipo kuphulika kwakung'ono (mwachidziwitso chodziwika bwino) ndi ming'alu idzachitika pofinya.

(2) The inductor (koyilo) ndi mbali yaikulu ya kuwotcherera mbali ya mkulu pafupipafupi welded chitoliro. Kusiyana pakati pa izo ndi chubu akusowekapo ndi m'lifupi mwa kutsegula ndi chikoka chachikulu pa kuwotcherera khalidwe.

① Kusiyana pakati pa inductor ndi chubu chopanda kanthu ndi chachikulu kwambiri, zomwe zimapangitsa kutsika kwakukulu kwa inductor;
Ngati kusiyana pakati pa inductor ndi chubu chopanda kanthu ndi kochepa kwambiri, n'zosavuta kutulutsa magetsi pakati pa inductor ndi chubu chopanda kanthu, zomwe zimayambitsa ming'alu yowotcherera, komanso zimakhala zosavuta kuonongeka ndi chubu chopanda kanthu.

② Ngati m'lifupi mwake mwaindukitala ndi wamkulu kwambiri, kumachepetsa kutentha kwapang'onopang'ono kwa chubu chopanda kanthu. Ngati kuthamanga kwa kuwotcherera kuli kofulumira, kuwotcherera zabodza ndi ming'alu zitha kuchitika pambuyo kuwongola.

Popanga mapaipi otsekemera othamanga kwambiri, pali zinthu zambiri zomwe zimayambitsa ming'alu ya weld, ndipo njira zopewera ndizosiyana. Pali zosinthika zambiri pamawotchi apamwamba kwambiri, ndipo vuto lililonse la ulalo limakhudza mtundu wa kuwotcherera.
