iimveliso

Inxalenye yentsimbi enzulu yokudweba isitampu yindlela yokwenza i-workpiece (ucinezela inxalenye) yemo kunye nobukhulu obufunwayo ngokufaka amandla angaphandle kwipleyiti, umcu, umbhobho, iprofayili, kunye nokunye okunjalo ngokushicilela kunye nokufa. (umngundo) ukubangela ukuguquka kweplastiki okanye ukwahlula.Ukunyathela kunye nokuqulunqa kukusebenza kweplastiki efanayo (okanye ukucutshungulwa koxinzelelo), ngokudibeneyo ebizwa ngokuba yi-forging.Izithuba ezifakwe isitampu ikakhulu zishushu eziqengqelekayo kunye neentsimbi eziqengqelekayo ezibandayo kunye nemicu.

Isitampu somzobo onzulu senziwa ikakhulu ngokunyathela kunye nokunyathela ngesinyithi okanye ngamashiti angeyontsimbi ngoxinzelelo loshicilelo.

Ikakhulu inezi mpawu zilandelayo:

1. Iinxalenye ezinzulu zomzobo wesitampu zenziwe ngokunyathela phantsi kwesiseko sokusetyenziswa kwezinto eziphantsi.Amalungu alula ngobunzima kwaye alungile ekuqineni, kwaye emva kokuba i-sheet material ikhubazeke ngeplastiki, isakhiwo sangaphakathi sesinyithi siphuculwe, ukwenzela ukuba iindawo zokunyathela ziphuculwe.Amandla anyukile.
2. Kwinkqubo yesitampu, ekubeni umphezulu wezinto eziphathekayo ungonakaliswanga, unomgangatho osemgangathweni ophezulu kunye nembonakalo egudileyo kunye nenhle, ebonelela ngeemeko ezifanelekileyo zokupeyinta komhlaba, i-electroplating, i-phosphating kunye nolunye unyango oluphezulu.

Xa kuthelekiswa ne-castings kunye ne-forgings, iinxalenye zesitampu ezizotyiweyo zincinci, zifana, zilula kwaye zomelele.Ukunyathela kunokuvelisa izixhobo zokusebenza ezineembambo, iimbambo, undula okanye i-flanging ekunzima ukuyivelisa ngezinye iindlela zokwandisa ukuqina kwazo.Ngombulelo ekusebenziseni ukubumba okuchanekileyo, ukuchaneka kwendawo yokusebenza kufikelele kwi-micron kwaye ukuphindaphinda kuphezulu.

Iimpawu zesakhiwo seendawo ezinzulu zomzobo:

1. Ubume beendawo ezizotyiweyo kufuneka zibe lula kwaye zilinganiswe ngokusemandleni, kwaye kufuneka zidwetshwe ngokusemandleni;
2. Kwiindawo ezifuna ukujula ngamaxesha amaninzi, iindawo zangaphakathi kunye nezangaphandle kufuneka zivunyelwe ukuba zibe nemikhondo enokuthi yenzeke ngexesha lokudweba, ngelixa liqinisekisa umgangatho oyimfuneko;
3. Ngaphantsi kwesiseko sokuqinisekisa iimfuno zendibano, udonga olusecaleni lwelungu lomzobo olunzulu luya kuvunyelwa ukuba lube nokuthambekela okuthile;
4. Umgama ukusuka kumda womngxuma okanye umda weflange ukuya eludongeni olusecaleni kufuneka ulungele;
5. Umzantsi kunye nodonga lwesiqwenga somzobo onzulu, i-flange kunye nodonga, kunye ne-radius yekona yeembombo zecandelo loxande kufuneka zifaneleke.Thatha i-radius yekona yecala elisezantsi kunye nodonga lwecandelo lomzobo 1pr = 1.5mm, mm1r2p =, umzobo onzulu we-flange kunye I-radius yekona yodonga mm2rd1 =, mm5.1r2d =;

Izinto ezisetyenziselwa ukuzoba zifuneka ngokubanzi ukuba zibe neplastiki elungileyo, umlinganiselo wesivuno esiphantsi, i-coefficient ye-plate enkulu yobukhulu be-directivity coefficient, kunye ne-direction yeplate encinci.
