Metal jakisoni akamaumba⎮Powder Metallurgy⎮Zambiri zaife

• Kupanga ufa ndi gawo lachiwiri la zitsulo za ufa. Ndi njira yomwe ufa wotayirira umapangidwa kukhala ma billets ndi mawonekedwe, kukula, kachulukidwe ndi mphamvu.

• Ufa kudzera mu njira yopangira kuti mupeze mawonekedwe opatsidwa ndi mphamvu ya thupi la ufa, lotchedwa compact.

Pali njira zambiri zopangira ufa, kuwonjezera pa njira yamba youmba, enawo amagawidwa ngati njira zapadera zopangira. Kupanga ufa ndiye njira yofunika kwambiri.

kusowa makina osindikizira - kuponyera zamkati - kutayira kotayirira

Njira zotsatirazi zimagwiritsidwa ntchito popanga zinthu: kuthamanga, kufa, kutentha, isostatic, rolling, centrifugal, extrusion, ndi kuphulika.

• Njira zapadera zopangira;

• kuumba wamba;

•ufa pretreatment;

• chiphunzitso cha kupondereza

Kukonzekera kwaufa kumaphatikizapo kutsekereza, kuyesa, kusakaniza, granulating, ndi kuwonjezera mafuta, mwa zina.

Wamba ufa kufa kupanga

Kufa kupanga ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga ufa. Zimatanthawuza njira yodzaza ufa wosakanikirana wosakanikirana mu nkhungu yotsekedwa mu kuchuluka kwa kutentha kwa firiji, ndiyeno kukanikiza mu billet ndi mphamvu inayake ya unit ndi atolankhani.

Kupanga kumeneku nthawi zambiri kumakhala ndi masitepe otsatirawa: kuyeza ufa, kudzaza ufa, kukanikiza, kugwira kukakamiza ndi kuvula.

Mfundo yakuumba

(1) Gwiritsani ntchito nkhungu kuti ufawo ukhale wofunika.

(2) Perekani thupi pa kukula kwake kwake.

(3) Tchulani porosity yofunikira ya billet ndi mtundu wa porosity.

(4) Perekani thupi ndi mphamvu yoyenera ndi kachulukidwe kuti mugwire.

Kukanikiza njira

Kuponderezedwa kwapadziko lonse: nkhonya ya concave imafa ndipo nkhonya yapansi sisuntha, ndipo nkhonya yapamwamba imakhala yoponderezedwa ndi unidirectional.

Njira ziwiri zisanachitikessing: kufa kwa concave kumakhazikika, ndipo nkhonya yapamwamba ndi yapansi imapanikizidwa nthawi yomweyo ndi zovuta zofanana ndi zosiyana.

Kukanikiza koyandama: nkhonya yapansi imakhazikika, concave die imathandizidwa ndi akasupe, masilindala, masilindala, etc., ndipo imatha kuyandama pambuyo popsinjika.

Kukanikiza ndondomeko

The kukanikiza ndondomeko akhoza kugawidwa mu magawo anayi:

(1) Tizidutswa ta ufa timasuntha, ma pores amachepa, ndipo tinthu tating'onoting'ono timafinyanirana;

(2) Ufa umakanizidwa mwamphamvu, ndipo tinthu tating'onoting'ono timadzaza mumpata pakati pa tinthu tating'onoting'ono, ndipo tinthu tating'onoting'ono timayamba kuwonongeka;

(3) The concave ndi otukukira pansi mbali ya pamwamba pa tinthu ufa ndi mbamuikha ndi meshed mu olimba kukhudzana boma;

(4) Ntchito kuumitsa kwa tinthu tating'onoting'ono mpaka malire, kumawonjezera kupanikizika, tinthu tating'ono ta ufa timawonongeka ndipo crystallization imayengedwa.

Ubale pakati pa kuuma kwa chitsulo ufa ndi kukakamiza kukanikiza

Zotsatira za chiyero cha ufa

Chifukwa cha njira zosiyanasiyana zopangira ufa, chiyero cha ufa sichifanana, ndipo ufa uli ndi zonyansa zina. Zonyansa mu ufa zambiri mu mawonekedwe a zitsulo oxides.

The zitsulo okusayidi ufa makamaka wolimba ndi Chimaona, ndipo makamaka anagawira pamwamba pa zitsulo ufa, amene kumawonjezera kukanikiza kukaniza ndi kuwonongeka kukanikiza ntchito.

The manufacturability wa ufa kupanga magawo kapangidwe

1. Kuti kupanga nkhungu ndi kuphatikizika kukhala kosavuta, yesetsani kusankha njira yowongoka, yofanana yomwe imapewa kusiyana kwakukulu kwa gawo ndi grooving yopapatiza, malo ozungulira, ndi zina zotero.

2. Pewani makoma opyapyala am'deralo kuti muchepetse ufa ndikupewa ming'alu.

3. Pewani ma grooves ndi mabowo m'makoma am'mbali kuti muchepetse midadada yotsalira.

4. Pewani kukulitsa gawo lodutsa gawo limodzi ndi njira yolimbikitsira kuti muthandizire kuphatikizika. Makona ayenera kuzunguliridwa pamphambano za khoma lililonse kuti azitha kukhazikika komanso kupewa kupanikizika.

Chigawo Chopanga Ufa

Mtundu woyamba wa magawo: kukanikiza unidirectional, khoma woonda, mawonekedwe amasinthasintha, tebulo gawo (khoma makulidwe nthawi zambiri mpaka 6.35mm)

Gawo lachiwiri la gawo: gawo la tebulo, kutalika kulikonse ndi mawonekedwe, liyenera kukhala magawo awiri okakamiza.

Gawo lachitatu: Gawo la matebulo awiri, a msinkhu uliwonse ndi mawonekedwe, omwe ayenera kukanikizidwa mbali zonse ziwiri

Mtundu wachinayi wa zigawo: Mipikisano tebulo, kutalika kulikonse ndi mawonekedwe, ayenera kugwiritsa ntchito multi-fa stamping bidirectional kukanikiza mbali
