Hlau txoj kev - Casting

Ib txoj kev tsim khoom uas ua kua hlau yog nchuav rau hauv pwm kab noj hniav uas haum rau cov duab thiab qhov loj ntawm ib feem, thiab tom qab ntawd txias thiab khov kom tau txais ib qho khoob lossis ib feem feem ntau hu ua kua hlau ua los yog casting.Piv txwv li, peb cov khoom:brake poj niam inverted flare hose, 6/8 ib 10poj niam rau txiv neej khub hlau roj Circuit Court hloov kho connector, ib 3 / an4 / an6 / an8 / an10poj niam flare viav vias hloov ob sab poj niam aluminium khub hlau.

Txheej txheem khiav: kua hlau → pwm filling → solidification shrinkage → casting

Cov yam ntxwv ntawm txheej txheem:

1. Nws tuaj yeem tsim cov khoom lag luam nrog cov duab sib txawv, tshwj xeeb tshaj yog cov uas muaj cov kab noj hniav hauv cov kab noj hniav.

2. Strong adaptability, unlimited alloy hom thiab yuav luag unlimited casting ntau thiab tsawg.

3. Cov khoom siv dav dav, tshem tawm cov khoom pov tseg thiab cov cuab yeej siv qis.

4. Cov khib nyiab siab, qhov chaw tsis zoo thiab kev ua haujlwm tsis zoo.

Casting Classification:

(1) Sand casting

Ib txoj hauv kev los tsim cov castings hauv cov xuab zeb pwm.Hlau, hlau thiab feem ntau non-ferrous alloy castings tuaj yeem tau los ntawm xuab zeb casting.

Technical nta:

1. Nws yog tsim rau kev ua blanks nrog cov duab complex, tshwj xeeb tshaj yog nrog cov kab noj hniav complex;

2. Kev hloov pauv dav dav thiab tus nqi qis;

3. Rau qee cov ntaub ntawv uas tsis zoo plasticity, xws li cov hlau cam khwb cia, xuab zeb casting yog tib txoj kev tsim rau kev tsim nws cov khoom lossis cov khoom seem.

Daim ntawv thov: tsheb cav lub tog raj kheej thaiv, lub tog raj kheej taub hau, crankshaft thiab lwm yam castings

(2) Kev nqis peev casting

Feem ntau, nws yog hais txog cov txheej txheem casting nyob rau hauv uas tus qauv yog ua los ntawm cov ntaub ntawv fusible, ob peb txheej ntawm cov ntaub ntawv refractory yog coated rau saum npoo ntawm cov qauv los ua lub plhaub pwm, thiab tom qab ntawd cov qauv yog yaj tawm ntawm lub plhaub pwm, yog li. raws li kom tau ib tug pwm tsis parting nto, uas yuav tsum tau sau nrog xuab zeb thiab poured tom qab high-temperature roasting.Nws feem ntau hu ua "poob ciab casting".

qhov zoo:

1. High dimensional precision thiab geometric raug;

2. High deg roughness;

3. Nws muaj peev xwm nrum casting nrog ib tug complex zoo thiab cov cam khwb cia hlau yog tsis txwv.

Disadvantages: txheej txheem nyuaj thiab tus nqi siab

Daim ntawv thov: nws muaj feem xyuam rau kev tsim cov khoom me me nrog cov duab nyuaj, cov kev xav tau raug siab, lossis nyuaj rau kev ua tiav hauv lwm txoj hauv kev, xws li turbine cav hniav.

(3) Tuag casting

Kev kub siab yog siv los nias molten hlau mus rau hauv lub precision hlau pwm kab noj hniav ntawm kev kub ceev, thiab cov hlau molten yog txias thiab solidified nyob rau hauv siab los tsim ib tug casting.

qhov zoo:

1. Kev kub siab thiab ceev ceev ntawm cov kua hlau thaum lub sij hawm tuag casting

2. Cov khoom zoo, ruaj khov loj thiab zoo sib hloov;

3. Kev ua haujlwm siab ntau lawm, siv sijhawm ntau dua ntawm kev tuag-casting;

4. Nws yog tsim rau kev tsim khoom loj thiab muaj txiaj ntsig zoo rau kev lag luam.

Qhov tsis zoo:

1. Cov castings yog ib qho yooj yim los tsim cov pores zoo thiab shrinkage porosity.

2. Cov tuag casting muaj tsawg plasticity thiab tsis haum rau kev ua hauj lwm nyob rau hauv tej yam load thiab kev co;

3. Thaum siab melting point alloy yog siv rau tuag casting, pwm lub neej yog tsawg, uas cuam tshuam rau expansion ntawm tuag casting ntau lawm.

Daim ntawv thov: tuag casting yog thawj zaug siv hauv kev lag luam tsheb thiab ntsuas kev lag luam, thiab tom qab ntawd maj mam nthuav dav mus rau ntau yam kev lag luam, xws li cov tshuab ua liaj ua teb, tshuab cuab yeej kev lag luam, hluav taws xob kev lag luam, kev lag luam tiv thaiv hauv teb chaws, khoos phis tawj, khoom siv kho mob, watches, koob yees duab, kho vajtse txhua hnub thiab lwm yam kev lag luam.
