Qhov Pog Tsis Nyob Rau Lis Tshaj Ym Nploos Thawj Compacting Process?

Time: 2024-01-06

1. Cov qhov ntawv tawm dub li cas nyob rau txog cov ntsiab thiav

Koj tawm mus rau hauv tau thiab qhov noj ntau ntawd, rooj kawg muaj los yuav ua hauv lawv, nyob rau hauv lub tsis npaug thiab qhov noj ntau ntawd. Yog li, rooj kawg thiab cov xwm rooj kawg nrog qhov noj ntau ntawd ib tug xaiv yog cov phooj ywg thiab qhov txog thiab ntawm. Koj tus thaum yog cov qab ntau ntawd thiab qhov thiaj thiab ntawm, rooj kawg nrog qhov green compact yog ib tug xaiv yog mus ua hauv lawv. Rau hauv cov phooj ywg thiab rooj kawg, li cas li, cov qab ntau ntawd thiab qhov txog thiab ntawm mus yuav ua hauv lawv peb cov xaiv.

2, Qhov txog thiab ntawm mus paub cov txheej

2.1 Qhov txog thiab ntawm radial mus paub thiab qhov txog thiab ntawm lub hmoob mus paub

Cov qab ntau ntawd thiab qhov txog thiab ntawm mus ua hauv lawv peb cov phooj ywg thiab manufacturing. Yog li cas li, cov qab ntau ntawd thiab qhov txog thiab ntawm mus ua hauv lawv peb cov phooj ywg (ib tug xaiv yog cov powder composition, compact density, sintering process, thiab). Yog li cas li, cov qab ntau ntawd thiab qhov txog thiab ntawm mus ua hauv lawv peb cov phooj ywg, yog li cas li, cov qab ntau ntawd thiab qhov txog thiab ntawm mus ua hauv lawv peb cov phooj ywg.

2.2 Qhov txog thiab ntawm axial mus paub

Thaw kawg tsev nyob rau hauv lub compacts, muaj teb chaw cov powder size, thiaj cov pressing pressure los yuav tsum npawb holding time, thiab muaj teb chaw thiab lawv nrog cov axial dimension. Rau hauv lub step press blank, cov step height dimension yog muaj teb chaw tau rau hauv cov forming position tawm combined die punch, cov powder loading ratio nrog txheej ib, thiab cov running speed tawm floating die punch.

3, Cov geometric tolerance yog out of tolerance

3.1 Straightness

Cov ntawv ntawm straightness difference yog: straightness tawm mold yog tsis paub, cov density distribution tawm compact yog tsis ua hauj, thiab cov wall thickness tawm compact yog tsis ua hauj.

3.2 Parallelism

Nyob li cas teb chaw ntawm: cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, thiab cov xym nyob rau hauv txoj cai.

3.3 Coaxiality

Nyob li cas teb chaw coaxiality: cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, cov ntsuam nrog qhov tswj rau hauv lub kawg thiab kev pab tswj rau hauv lub tsis muaj tau, thiab cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, thiab cov xym nyob rau hauv txoj cai.

Rau hauv lub tas los yog tau, cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, cov kawg thiab kev pab tswj rau hauv lub tsis muaj tau, thiab cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau thiab cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, thiab cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau, cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau thiab cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau thiab cov ntsuam nrog qhov tswj rau hauv lub tsis muaj tau.

4, Cov phooj ywm nyob rau hauv tsis muaj

Tsis txhawb rau hauv peb compacts, cov tsis ntawv no yog: lub xyoo yam, ntsuam ntsiab thiab ntsuam tsev, tshaj ntawd, thiab qhov tsis muaj teeb tagaub.
