indlela yokukhetha isikhunta esifanele kanye necala lokulahlekelwa ukufa

Ukukhetha isikhunta
I-Die Material Selection iyisixhumanisi esibaluleke kakhulu kuyo yonke inqubo yokwenza ukufa. I-Die Material Selection idinga ukuhlangabezana nezimiso ezintathu, fa ukuze uhlangabezane nokumelana nokugqoka, amandla nokuqina nezinye izidingo zomsebenzi, fa ukuze uhlangabezane nezidingo zenqubo, futhi kufa kufanele kuhlangabezane nokusebenza kwezomnotho. Isimo sokugoqa sidinga
1. Ukugqoka ukumelana. Lapho okungenalutho kufakwe ngepulasitiki emgodini wokufa, iyageleza futhi ishelele ebusweni bomgodi wokufa, okubangela ukungqubuzana okukhulu phakathi kwendawo yomgodi wokufa kanye nokungenalutho, okuholela ekuhlulekeni kwefa ngenxa yokugqoka. Ngakho-ke, ukumelana nokugqoka kwempahla kungenye yezinto eziyisisekelo nezibalulekile ze-die. Ukuqina kuyisici esiyinhloko esithinta ukumelana nokugqoka. Ngenjwayelo, bukhuni ubulukhuni bezingxenye ezifayo, encane inani eligugile, kungcono ukumelana nokugqoka. Ngaphezu kwalokho, ukugqoka ukumelana nakho kuhlobene nohlobo, inani, uhlobo, usayizi nokusatshalaliswa kwe-carbides kundaba.
2. Ukuqina okuqinile, izimo zokusebenza zimbi kakhulu, ezinye zivame ukuthwala umthelela omkhulu, okuholela ekuqhekekeni okuqinile. Ukuze uvimbele izingxenye ezifayo emsebenzini wokuphuka okungazelelwe kwe-brittle, ukufa kufanele kube namandla aphezulu kanye nokuqina. Ukuqina kwe-die ikakhulukazi kuncike kokuqukethwe kwekhabhoni, usayizi wokusanhlamvu kanye ne-microstructure yezinto.
3. Ukukhathala kokuphuka ukusebenza, kufa emsebenzini kumphumela wesikhathi eside we-cyclic stress, ngokuvamile kuholela ekuqhekekeni kokukhathala. Izinhlobo zayo zihlanganisa ukuphuka kokukhathala okuphindaphindwayo okunamandla aphansi, i-tensile fatigue fracture, thintana nokukhathala ukuphuka kanye nokugoba ukukhathala ukuphuka. Ukukhathala nokuphuka kwefa ngokuyinhloko kuncike emandleni ayo, ubulukhuni, ubulukhuni, kanye nokuqukethwe kokufakwa kundaba.
4. Ukusebenza okuphezulu kwezinga lokushisa, lapho izinga lokushisa lokusebenza lesikhunta liphakeme, kuzonciphisa ubulukhuni namandla, okuholela ekugqokeni kokuqala kwesikhunta noma ukuguqulwa kwepulasitiki nokwehluleka. Ngakho-ke, impahla yokubumba kufanele ibe nokuzinza okuphezulu kwe-anti-tempering, ukuze uqinisekise ukuthi isikhunta ekushiseni okusebenzayo, ngobulukhuni obuphakeme namandla.
5. Ukumelana nokukhathala okubandayo nokushisayo. Ezinye ziyafa ziyashisisa futhi zipholiswe ngokuphindaphindiwe ngesikhathi sokusebenza, okwenza ubuso be

Umgodi wokufa ungaphansi kwengcindezi kanye nengcindezi yokucindezela, kubangela ukuqhekeka nokuqhekeka kwendawo, kwandisa ukungqubuzana, futhi ivimbela ukuguqulwa kwepulasitiki, kuncishiswe ukunemba kweDimensional, okuholela ekuhlulekeni kwesikhunta. Ukukhathala okubandayo nokushisayo kungenye yezindlela eziyinhloko zokuhluleka kokufa okushisayo, futhi lolu hlobo lokufa kufanele lube nokumelana nokukhathala okukhulu nokushisayo. 6. Ukumelana nokugqwala, ezinye isikhunta ezifana isikhunta plastic emsebenzini, ngenxa yokuba khona kwe-chlorine, i-fluorine nezinye izakhi epulasitiki, ukushisa ngemuva kokubola ukuphuma kwe-HCI, I-HF kanye nenye igesi edlayo enamandla, ukuguguleka kwesikhunta umgodi ongaphezulu, andise ubuhwaba bayo obuphezulu, ukwandisa ukwehluleka kokugqoka.
1) Izinto zezingxenye eziyinhloko zokusebenza zesikhunta azikhethiwe ngendlela engafanele. Izinto ezisetshenziswayo zisebenza kabi futhi azikwazi ukumelana nokuguga; insimbi yokufa ayizange icwengisiswe futhi inenani elikhulu lamaphutha okuncibilika; isikhunta concave kanye concave, ukubumba izikhala kanye nenqubo yokuqamba ayiphelele, futhi kunezingozi ezifihliwe zokwelashwa kokushisa.

2) Inkinga yesakhiwo sefa, isakhiwo sokufa asinangqondo. I-punch ezacile ayiklanyelwe ngedivayisi yokuqinisa, imbobo yokukhipha ayibushelelezi futhi iyanqwabelana, futhi amandla okukhipha makhulu kakhulu, futhi i-punch ingaphansi komthwalo oshintshanayo owandisiwe.

3) I isikhunta ukwenza inqubo ayiphelele, okubonakaliswa kakhulu izinga eliphansi langaphakathi le-convex ne-concave die forging blanks, kanye nobuchwepheshe bokwelapha ukushisa kanye nenqubo kunezinkinga, okuholela ekukhunjweni kwe-convex kanye ne-concave kungacimi ngokuphelele, izindawo ezithambile nobulukhuni obungalingani. Ngezinye izikhathi ama-microcracks noma ngisho nokuqhekeka kwenzeka, ukugaya nokupholisha akukho endaweni, kanye nevelu yobunzima obungaphezulu bukhulu kakhulu.

4) Akukho lubrication noma lubrication kodwa umphumela omubi
