Anataya thovu kuponyera

 1.1 Mwachidule

Mu 1958, HF Shroyer adapanga ukadaulo wopanga zitsulo zopangidwa ndi pulasitiki wonenepa ndipo adapeza patent. Mtundu womwe udagwiritsidwa ntchito poyamba udapangidwa ndi bolodi la polystyrene (EPS) ndipo udapangidwa ndi mchenga wokhala ndi binder. Makampani aku Germany a Grunzweig ndi Harrtmann adagula patent iyi ndikuikulitsa ndikuigwiritsa ntchito. Ukadaulo wogwiritsa ntchito mchenga wopanda youma kuti apange ma castings pambuyo pake adavomerezedwa ndi TRSmith mu 1964. Pambuyo pa 1980, kugwiritsa ntchito mchenga wopanda mchenga wouma kuyenera kuvomerezedwa ndi Full Mold Process (Inc). Pambuyo pake, chivomerezo sichinali chovomerezeka.

Njira yodziwika bwino komanso yothandiza ndikuyika mtunduwo wokutidwa ndi zinthu zosakanikirana mubokosi lamchenga, kudzaza mtunduwo ndi mchenga wouma mwamphamvu, ndikutsanulira chitsulo chamadzi m'malo mwa chithovu. Njira yoponyera iyi imatchedwa: kutaya thovu (EPC), kuponyera nkhungu ndi kuponyera nkhungu zolimba, ndi zina zotero. Komiti Yotayika ya Foam Casting ya American Foundry Association idatengera "kutaya thovu" monga dzina la njirayi.

Anataya thovu kuponyera ndi njira yatsopano yoponyera yomwe ingagwiritsidwe ntchito popanga zida zamagetsi zosapanga dzimbiri komanso zopangira zitsulo, kuphatikiza: zotchinga, mitu yamiyala, ma crankshafts, mabokosi amagetsi, mapaipi olowera, mapaipi otulutsa utsi ndi mabuleki. Njira otaya akuponya thovu ndi awa:

1) Kutulutsa thovu
Kupanga mitundu ya modelo ndi gawo loyamba la njira yoponyera thovu. Pazipangizo zovuta monga mitu yamiyala, mitundu ingapo ya thovu imayenera kupangidwa padera, kenako ndikulumikiza mtundu wonse. Mtundu uliwonse wamabokosi umafuna nkhungu zopangira. Kuphatikiza apo, nkhungu zingafunike pakugwiritsa ntchito gluing kuti pakhale malo oyenera. Njira yojambulira yachitsanzo idagawika magawo awiri. Gawo loyamba ndikupanga mikanda ya polystyrene imakulitsidwa mpaka kukula kokwanira, komwe kumachitika ndikutentha mwachangu ndi nthunzi. Gawo ili limatchedwa pre-kukuza.

2) Model kupanga
Mikanda chisanadze kukodzedwa ayenera kukhazikika poyamba, ndiyeno kutumiza kwa hopper makina akamaumba, ndi kudyetsedwa kudzera dzenje kudya. Nkhungu ikadzaza ndi mikanda yomwe idakonzedweratu, nthunzi imayambitsidwa kuti ifewetse mikanda. Kukula, kudzaza mipata yonse ndikulumikiza thupi limodzi, motero kumaliza ntchito yopanga chithovu, gawo ili limatchedwa autoclave molding.

Pambuyo pakuumba, nkhunguyo imakhazikika ndi kutuluka kwakukulu kwamadzi m'mimbamo yamadzi utakhazikika, kenako nkhunguyo imatsegulidwa kuti ichotse nkhunguyo. Pakadali pano, kutentha kwa nkhungu kumawonjezeka ndipo mphamvu ndiyotsika. Chifukwa chake, chisamaliro chiyenera kutengedwa pakuchepetsa ndi kusunga kuti tipewe kupindika ndi kuwonongeka.

3) Model limodzi kuphatikiza
Chitsanzocho chisanagwiritsidwe ntchito, chimayenera kusungidwa kwa nthawi yoyenera kuti chikhale chokhwima komanso chokhazikika. Nthawi yosungirako mitundu imakhala mpaka masiku 30. Mtundu wopangidwa ndi nkhungu wopangidwa mwapadera, umangofunika kusungidwa kwa maola awiri. Mtunduwo utakhwima ndi kukhazikika, utha kugawidwa magawo awiri. Zolembazo zimamangirizidwa palimodzi.
Chojambulira cha block block chimachitika pamakina ogwiritsa ntchito otentha osungunuka. Malo ophatikizikawo ayenera kutsekedwa mwamphamvu kuti athe kutaya zolakwika.

4) Model limodzi kuviika coating kuyanika
Pofuna kupanga zojambula zambiri pa bokosi, nthawi zina mitundu yambiri imamangiriridwa m'magulu, ndipo masango amitundu amamizidwa mu utoto wonyezimira, kenako amawuma mu uvuni woyendetsera mpweya pafupifupi 30-60C (86-140F) kwa 2 mpaka 3 Pambuyo pake maola, youma, ikani gulu lachitsanzo mu bokosi lamchenga, mudzaze ndi mchenga wouma ndi kunjenjemera mwamphamvu. Miphika yonse yamkati ndi mchenga wakunja wouma wa masango achitsanzo ayenera kuphatikizika ndikuthandizidwa.

5) Kutsanulira
Tsango lachitsanzo likadzazidwa ndi mchenga wouma m'bokosi lamchenga, nkhungu imatha kutsanulidwa. Chitsulo chosungunuka chikatsanulidwira muchikombole (kutentha kwake kumakhala pafupifupi 760C / 1400F kwa aluminiyamu woponyedwa, ndipo pafupifupi 1425C / 2600F yachitsulo chosungunuka), mtunduwo umasandulika. Chitsulo chimasinthidwa ndikupanga kuponyera. Chithunzi 1 ndi chithunzi cha bokosi lamchenga ndikutsanulira njira yotayika ya thovu.

Mu ndondomeko yotayika ya thovu, kuthamanga kothamanga ndikofunikira kwambiri kuposa kuponyera kwachikhalidwe. Ntchito yothira ikasokonezedwa, nkhungu yamchenga imatha kugwa ndikuwononga. Chifukwa chake, kuti muchepetse kusiyana pakati pakuthira kulikonse, ndibwino kugwiritsa ntchito makina othira okha.

 Chithunzi 1 Chithunzi cha bokosi lamchenga ndikutsanulira kwa chithovu chotayika
6) Kugwa kwa mchenga
Mukatsanulira, kuponyako kumakhazikika ndikukhazikika m'bokosi lamchenga, kenako nkugwa mumchenga. Mchenga womwe umaponyedwayo ndi wosavuta, ndipo zoponya zimatuluka mumchenga wouma pomwe sandbox igubuduzika. Pambuyo pake, zoponyazo zimasiyanitsidwa zokha, kutsukidwa, kuyang'aniridwa, ndikunyamulidwa mubokosi loponyera.

Mchenga wouma ukhoza kugwiritsidwanso ntchito utazirala, ndipo njira zina zowonjezera sizimagwiritsidwa ntchito kawirikawiri. Chitsulo chachitsulo chimatha kusinthidwa ndikugwiritsidwa ntchito popanga.

1.2 Ubwino wa njira yotayika yoponyera thovu

Njira yotayika yoponya thovu ili ndi maubwino pazinthu zitatu zazikuluzikulu: ukadaulo, chuma ndi kuteteza zachilengedwe.

1.2.1 Luso
