Mutu 3: Njira Yopangira Zofukula za Excavator Boom "Basic Work" Plate Leveling and Beveling

Popanga mkono wofukula, "kuwongolera mbale ndi kugwedeza" ndizofunikira kwambiri pazochitika zonse. Ngakhale kuti si ulalo wowonekera kwambiri, uli ngati chithandizo cha maziko musanamange nyumba, zomwe zimatsimikizira ngati kuwotcherera, kusonkhanitsa, ndi kulondola kwazithunzi kungakhale "koyenda bwino".

Lero tikambirana zomwe sitepeyi ikuchita, momwe tingachitire, komanso chifukwa chake singapulumutsidwe.

3.1 Chifukwa chiyani kuwongolera kuli kofunikira?

N’cifukwa ciani tifunika “kucita cidwi”? Kodi mbale yachitsulo si yathyathyathya ukadula?

Kwenikweni, sichoncho.

Pambuyo podula lawi kapena plasma, mbale yachitsulo imakhala ndi mawonekedwe owoneka bwino, kupsinjika kwamafuta kapena kupotoza pamakona. Izi zopindika zing'onozing'ono, muzofukula zofukula, mkono wotambasula, mkono woyendetsa mulu ndi zigawo zina zomangira zomwe zimatalika kuposa 10 metres ndikulemera matani angapo, ngakhale kupatuka kwa 2 mm kungayambitse:

· Weld msoko "misalignment" ndi undercut;

· Msonkhano wotsatira sukugwirizana ndi dzenje;

· Zotsalira za nkhawa ndende pambuyo kuwotcherera, ngakhale "ming'alu" patapita zaka zingapo ntchito.

Choncho, mbale yachitsulo iyenera kukanikizidwa mobwerezabwereza pogwiritsa ntchito makina osakanikirana ndi ma seti angapo apamwamba ndi otsika kuti athetse nkhawa zamkati ndikubwezeretsa flatness.

Mfundo zazikuluzikulu za kusanja:

· Kukhazikika kwa mbale yachitsulo kuyenera kuyendetsedwa mkati mwa ± 2mm / m;

· Mbali zonse ziwiri za mbale yachitsulo ziyenera kukanikizidwa nthawi imodzi kuti zisawonongeke;

· Kwa mbale zachitsulo zokulirapo (> 20mm), m'pofunika kuzisanja mobwerezabwereza m'magawo, ndipo sizingatheke "kuwakanikiza mpaka pansi pamtunda umodzi".

3.2 Kodi "kutsegula kotsetsereka" ndi chiyani?

Kodi "kuseka" ndi chiyani? N’cifukwa ciani tifunika kuseŵenzetsa m’mphepete mwa mbale?

Mwachidule: kupanga weld kukhala wolimba.

Mabala achitsulo wamba amakhala ndi mbali zowongoka. Ngati ali wowotcherera mwachindunji matako, kuya kwake sikokwanira ndipo weld ndi wosakhazikika. Kuphatikiza apo, chitsulo sichingaphatikizidwe mokwanira, zomwe zimatsogolera ku zovuta zowotcherera mosavuta monga kuwotcherera kozizira, ma slag inclusions, ndi pores.

Choncho, m'mphepete mwa mbaleyo uyenera kusinthidwa kukhala V-woboola pakati, X-woboola pakati kapena U-woboola pakati kuti ndodo yowotcherera kapena waya ilowe pansi ndi "kuluma" mbali ziwiri za mbale.

Mafomu a Common Groove:

Kumbali imodzi V-woboola pakati ndi mbali imodzi yokhotakhota, yogwira ntchito ku makulidwe ochepera kapena ofanana ndi 20mm; kawiri mbali X woboola pakati ndi mbali ziwiri symmetrically kupendekera, ntchito makulidwe 20-40mm; Zowoneka ngati K komanso zooneka ngati U zimagwiritsidwa ntchito pama mbale okhuthala, makulidwe akulu kuposa kapena ofanana ndi 40mm.

General control of groove parameters:

· Ngodya: 30 ° ~ 45 ° mbali imodzi, ngodya yofananira yosapitirira 65 °

M'mphepete mwake: 2 ~ 4mm

· "Kugwa pakona", "kung'amba m'mphepete" ndi "kuwotcha" sikuloledwa

Njira zopangira:

· Gulu lolunjika mbale m'mphepete → CNC moto / plasma beveling kudula makina

· Zigawo zooneka mwapadera → carbon arc gouging + kugaya

· Mwatsatanetsatane kwambiri → CNC mphero makina/roboti beveling kudula

3.3 Njira yabwino yowerengera

Njira yabwino yopangira groove ndikukonzekera kuwotcherera kwamitundu yambiri ndikuwonjezera mphamvu ya solder ndi kuchuluka kwa zigawo za weld. Kodi chingachitike ndi chiyani ngati sitepeyi sinachitidwe bwino?

· Kusintha kwakukulu kowotcherera: Mphamvu yocheperako ya weld "idzakoka gawo lonse lokhota"

· Msonkhano Wovuta: Malo a dzenje sali ogwirizana, ndipo cholumikizira sichikhoza kukhazikitsidwa

· Kutopa kusweka: Kupsinjika kotsalira + kuwonongeka kwa kuwotcherera, kuwonongeka kwamapangidwe mkati mwazaka zingapo

Kukwera mtengo: Kukonzanso, kugaya, kukonzanso, kapena kukanda mkono wonse

Choncho, m’makampani amakambidwa kuti: “Ngati mbaleyo siiphwanyidwa bwino ndipo pobowoyo sinapangidwe bwino, ngakhale wowotcherayo atakhala wabwino bwanji, sizingakhale zothandiza.”

Mu chiganizo chimodzi:

"Plate leveling + beveling" ndi sitepe yoyamba kuti kuwotcherera khalidwe ndi poyambira kuti boom kuchoka "kuwotcherera angathe" mpaka "wowotcherera stably".

Zingakhale zosasangalatsa, koma popanda izo, kulondola, mphamvu, ndi chitetezo chonse chotsatira zidzakhala nkhani zopanda pake.
