Imibhobho yentsimbi ebandayoUkwandiswa kunye nokunciphisa indawo

I-Cold drawn yinkqubo yezinto, kwizinto zetsimbi, ezibhekiselele kumzobo ukuze kuphunyezwe imilo ethile kunye neempawu ezithile zomatshini, izinto eziphathekayo ziphantsi kweemeko zokushisa kwegumbi lokudweba.Iimveliso ezitsalwa ngokubanda xa zithelekiswa ne-thermoforming: ukuchaneka okuphezulu komgangatho kunye nezibonelelo ezilungileyo zokugqiba umphezulu.

Umzobo omkhulu umbhobho wentsimbi Elongation (σ), kuvavanyo lwe-tensile, Ubude besampulu emva kwe-snap uluhlu lwayo lwenyuka njengepesenti yobude begeji yoqobo ebizwa ngokuba yi-elongation.Ngeσ ibonakaliswe ngeeyunithi ze%.Ifomula yile: apho : L1 - i-specimen yobude begeji eyaphukileyo, mm;I-L0 - ubude be-specimen gauge yasekuqaleni, mm.

Ukuzoba icandelo lombhobho omkhulu wedayamitha ukushwabana (ψ) kuvavanyo lwe-tensile, i-specimen enkulu yepesenteji yokunciphisa ubungakanani bendawo yokuqala ye-cross-sectional area yayo ye-cross-sectional kwi-necking pull off, eyaziwa ngokuba yi-shrinkage yecandelo.Ukuyaψ ibonakaliswe ngeeyunithi ze%.Kubalwa ngolu hlobo lulandelayo: apho: S0 – umboniso wokuqala we-cross-sectional area, mm2;I-S1 - i-specimen fractured necking ubuncinane i-cross-sectional area, mm2.

Isampulu yovavanyo lwe-tensile entanyeni yenkqubo yokuguqulwa kweplastiki.Emva koko ulwandiso lwesampulu lubonise ubungakanani obunqamlezileyo obunqamlekileyo ecaleni kwecandelo lentamo lomzekelo liqhubeka likhula, de isampuli yonke ibe yimeko yentamo.Ukuhla ngokukhawuleza kwentamo kwenzeka kwinqanaba loxinzelelo lwesivuno.Xa iqondo lobushushu umzobo yentsimbi kumanqaku kumzobo ngezantsi iqondo lobushushu recrystallization umzobo, kumzobo ngasentla iqondo lobushushu recrystallization kushushu umzobo kwiqondo lobushushu eliphezulu ngaphezu ubushushu begumbi ngaphantsi recrystallization lobushushu umzobo tsala.Ukuzoba ucingo lwentsimbi, umzobo wemveliso yocingo eyona ndlela iqhelekileyo.I-Thermal itsala ucingo ukuba lufudunyezwe ngaphambi kokungena kwi-orifice yokufa, intsimbi ephikisayo isetyenziselwa ukuzoba, njenge-tungsten, i-molybdenum kunye nezinye i-wire metal.Xa iqondo lobushushu tsala ucingo kufuneka kuphela ukutsalwa kumngxuma die yi heater ukuya kuluhlu lobushushu echaziweyo, ikakhulu ngocingo zinc, ucingo kunzima deformation ezifana ngesantya esiphezulu intsimbi, ethwele umzobo intsimbi.
