Lokacin da injiniyoyi suka ƙididdige sassa na aluminium don manifolds na ruwa, gidajen famfo, ko tsarin winch abin hawa, da wuya su fara da “simintin yashi.” Suna farawa da matsala: hawan keke mai zafi, matsananciyar haƙurin GD&T, daidaiton matsa lamba a mashaya 350+-da gefen sifili don ƙaramin porosity ko drift mai girma. Nan ne a yashi simintin aluminum factory ya daina zama mai siyarwa kuma ya zama haɓakar ƙira. A QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Mun ga gazawar sau uku masu maimaitawa a cikin ayyukan simintin yashi na aluminum-ba daga aikin kafa mara kyau ba, amma daga tsammanin da ba daidai ba a aikin injiniya.
Na farko: zaci "aluminum" yana nufin A380. Ba ya. A cikin shagonmu, 75% na simintin yashi na aluminum suna gudana akan A383 ko bambance-bambancen 319 da aka gyara musamman - musamman don ingantaccen ruwa a cikin tushen famfo mai bakin ciki da ingantacciyar injin bayan T6 magani mai zafi. Na biyu: ƙetare mold yashi hatsi rarraba. Muna amfani da silica mai haɗin gwiwa tare da sarrafa 45-75 µm gradation-ba don daidaitaccen tsari ba, amma saboda yana yanke ɓacin rai (Ra) da 30% tare da yashi kore na gargajiya, yana rage lokacin niƙa bayan simintin simintin a kan flanges na gidaje. Na uku: tsallake simintin FEA da aka riga aka yi na ƙaƙƙarfan raguwa. Wani abokin ciniki na Arewacin Amurka ya aiko mana da zanen famfo na piston tare da haƙarƙari mai kauri 22 mm kusa da bango 6 mm.

Abin da ke raba mai iyawa yashi simintin aluminum factory daga wanda ke isar da sassa masu mahimmanci? Haɗin kai tsaye-ba kawai simintin gyare-gyare ba, amma cikakkiyar sarkar daga zaɓin gami zuwa ingantaccen aiki. Muna samo takaddun ingots na aluminum kawai tare da cikakkun rahotannin gwajin niƙa (ASTM B179, EN 1706), sannan muyi nazarin OES akan kowane nau'in narkewa. Babu ware.

Wasu suna jayayya cewa simintin yashi ba zai iya daidaita simintin saka hannun jari ba don hadadden geometries na aluminum. Amma rikitarwa ba game da ƙidayar sashe ba - game da ƙaƙƙarfan ƙaƙƙarfan aiki ne. Nadi na tsakiyar winch yana buƙatar daidaitaccen rarraba jama'a, ƙare-ƙara saman ƙasa akan OD, da daidaitaccen daidaitawar maɓalli a tsayin mita 1.2. Simintin gyare-gyaren yashi wanda ya fi saka hannun jari lokacin da kaurin bango ya bambanta daga 8 mm zuwa 45 mm. Me yasa? Domin muna sarrafa adadin sanyaya ta hanyar sanyin gida da kuma sanya hannun riga-ba kawai kayan ƙira ba. Mun isar da simintin gyare-gyaren aluminium mai nauyin kilogiram 210 tare da Cpk> 1.67 akan ƙwanƙwasa masu mahimmanci, an tabbatar da su a ƙarƙashin kaya a ginshiƙan gwajin ruwa na mashaya 400.
Isar da kai ta duniya ta dogara akan abubuwa biyu da mafi yawan masu siye ke mantawa da su: shirye-shiryen kayan aiki da nuna gaskiya. Muna adana kayan A383 da 319 a cikin batches na kilogiram 500 - an riga an yi nazari, an bushe, shirye don narke cikin sa'o'i 24 na tabbatar da oda. Kuma muna raba sabbin abubuwan samarwa na lokaci-lokaci: ba wai kawai “an fara simintin simintin gyare-gyare ba,” amma “taron da aka gama da ƙarfe 09:22, zuba da aka shirya don 14:00, ana tsammanin girgizawa a 18:40.” Wannan hangen nesa yana ba ƙungiyoyin saye damar daidaita kayan aiki, ƙungiyoyin QA suna tsara ramummuka na CMM, da injiniyoyin ƙira su inganta girman rubutun farko kafin fara ayyukan sakandare.
