Unyango lobushushu kwi-Intanethi-lokucima kunye nonyango olushushu | umbhobho wentsimbi ukucima kunye nokufutha | ukucima intsimbi ejikelezayo kunye nokuthambisa

Ukucima kunye nokubila yinkqubo ebanzi yonyango lobushushu lokucima kunye nobushushu obuphezulu. Uninzi lwamalungu acinyiweyo kunye nobushushu asebenza phantsi komthwalo omkhulu oguqukayo. Baphantsi koxinzelelo, ukucinezelwa, ukugoba, ukukrazula okanye ukuchetywa. Eminye imiphezulu ikwanazo nokukhuhlana, kufuna iqondo elithile lokumelana nokunxiba njalo njalo. Ngamafutshane, amalungu asebenza phantsi koxinzelelo olwahlukeneyo. Ezo ndawo ziziindawo zolwakhiwo koomatshini abahlukeneyo kunye nezixhobo, ezinje ngeeshafti, iirodi zokudibanisa, iibholithi, iigiya, njl.njl., ezidla ngokusetyenziswa kwimizi-mveliso enjengezixhobo zoomatshini, iimoto kunye neetrektara. Ngokukodwa kumacandelo amakhulu kwimveliso yomatshini onzima, ukucima kunye nonyango olushushu lusetyenziswa ngakumbi. Ngoko ke, ukucinywa kunye nokunyamezela unyango kuthatha indawo ebaluleke kakhulu kunyango lobushushu.

Ngokweemeko zokusebenza zamacandelo kunye nokuqinisekisa iimfuno zokusebenza kwamacandelo, njengokugqiba ukukhethwa kokucinywa kunye nokunyamezela unyango, into yokuqala ekufuneka iqwalaselwe ngumbuzo wensimbi esetyenziselwa ukucima kunye nokufudumala. Ngokubanzi, ezi ngongoma zilandelayo kufuneka ziqwalaselwe:

1. Ngokubhekiselele ekusebenzeni kwenkqubo, ngaphezu kokunyanzeliswa okulungileyo kunye nokunyanzeliswa, eyona nto ibaluleke kakhulu kukuqina. Ngenxa yokuba ukusebenza kwensimbi kunqunywe yisakhiwo sensimbi, kwaye isakhiwo sensimbi sihambelana ngqo nokuqina kwayo. Ukuziqhelanisa kubonakalise ukuba intsimbi ineyona mpahla igqwesileyo yomatshini emva kokuqina ngokupheleleyo kunye nokucaphuka ngokufanelekileyo. Xa inxalenye iqiniswe ngokupheleleyo, kungakhathaliseki ukuba i-carbon steel okanye i-alloy steel, kufuneka ihlanjululwe kubunzima obufanayo, kunye nokuqina kwayo, amandla okuvelisa kunye namandla okudinwa ngokusisiseko kuyafana.

2. Ngokubhekiselele kwiimpawu zomatshini, emva kokuba intsimbi icinyiwe kwaye iyancipha, ukusebenza kufuneka kukwazi ukuhlangabezana nezibonakaliso zokusebenza ezifunwa ngamacandelo. Ngokweemfuno zokusebenza koomatshini kwiindawo ezininzi ezicinyiweyo kunye nobushushu, izikhombisi zayo zokusebenza zingaphakathi kolu luhlu lulandelayo. Σb: 600-1200MPa. Σs : 320-800 MPa. . Σs/σb : 50-60% σ-1 : 380-620MPa. Δ : 10-20% ψ : 40-50%
