I-metallurgy yomguboyinzululwazi kunye neteknoloji ephonononga kwaye yenze umgubo wesinyithi ohlukeneyo kwaye isebenzise umgubo njengemathiriyeli ekrwada ukulungisa imathiriyeli yesinyithi kunye neemveliso ngokucinezela, ukuntywila kunye nokusetyenzwa okuyimfuneko okulandelayo. Yindlela yokuvelisa ngobuninzi kunye nokusika okuncinci okanye akukho nto, enokwenza iindawo zesakhiwo ezinemilo enzima kunye namandla aphezulu okwakhiwa ngelixa kuncitshiswa iindleko. Yeyona ndlela iphambili yokuveliswa kobunzima bokuthwala iinxalenye zokuzithambisa ngexabiso eliphantsi.
Izinto ezilungileyo zenkqubo ye-metallurgy yomgubo
Izinto eziluncedo: 1. Uninzi lweentsimbi eziphikisayo kunye neekhompawundi zazo, i-oxide dispersion i-alloys eyomeleziweyo, izinto eziphathekayo, izinto ze-ceramic kunye ne-cemented carbides zinokwenziwa kuphela ngeendlela ze-metallurgy powder.
2. Ekubeni indlela ye-metallurgy ye-powder inokucinezelwa kubungakanani bokugqibela besithuba esingenanto okanye imfuneko encinci yokucutshungulwa komatshini olandelayo, inokugcina kakhulu inani letsimbi kunye nokunciphisa iindleko zemveliso. Xa ukuveliswa kweemveliso nge-powder metallurgy, ilahleko yesinyithi i-1-5% kuphela. Xa ziveliswa ngeendlela eziqhelekileyo zokuphosa, ilahleko yesinyithi inokufikelela kuma-80%.
3. Ekubeni inkqubo ye-metallurgy ye-powder ayinyibiliki izinto eziphathekayo kwinkqubo yokuvelisa izinto, ayikayiki ukuxuba ukungcola, kwaye i-sintering iqhutyelwa kwi-vacuum kunye ne-atmosphere yokunciphisa, ingesabi i-oxidation, kwaye ayiyi kubangela nayiphi na into engcolileyo kwizinto eziphathekayo, ngoko ke kunokwenzeka ukuba ufumane ukucoceka okuphezulu. s imathiriyeli.
4. I-metallurgy ye-powder inokuqinisekisa ukuchaneka kunye nokufana komlinganiselo wokubunjwa kwezinto.
5. I-metallurgy ye-powder ifanelekile ukuvelisa iimveliso ezinesimo esifanayo kunye nenani elikhulu leemveliso, ngokukodwa iigiya kunye nezinye iimveliso ezixabisa kakhulu. Ukwenziwa ngomgubo wesinyithi kunokunciphisa kakhulu iindleko zemveliso.
Ukungalungi kweinkqubo metallurgy umgubo
1. Qwalasela ubungakanani benxalenye xa kungekho batch ubukhulu
2. Umrhumo wokubumba uphezulu kunobumba bokubunjwa
Umkhombandlela wophuhliso weizixhobo metallurgy umgubo kunye neemveliso
1. I-alloys esekelwe kwi-iron emele iya kuphuhliswa ibe yimveliso echanekileyo yomthamo omkhulu kunye neendawo eziphezulu zesakhiwo.
2. Ukuveliswa kwee-alloys eziphezulu kunye ne-microstructure efanayo, kunzima ukuyiqhuba kunye nokuxineka ngokupheleleyo.
3. Sebenzisa inkqubo yoxinaniso eyandisiweyo ukwenza iialloyi ezikhethekileyo zezigaba ezixubeneyo ezineoyile ngokubanzi.
4. Ukwenziwa kwezinto ezingafaniyo, i-amorphous, i-microcrystalline okanye i-alloys ye-metastable.
5. Ukucutshungulwa kweefom ezizodwa kunye nezingaqhelekanga okanye ukubunjwa kweengxenye ze-alloy.
Ukuphosa yinkqubo apho isinyithi sinyibilikiswa kulwelo oluhlangabezana neemfuno ezithile kwaye lugalelwe kumngundo. Emva kokupholisa, ukuqiniswa, kunye nokucoca, ukuphosa okunokwakheka kwangaphambili, ubungakanani kunye nokusebenza kufunyenwe.
Iimpawu zokuSasa:
1. Ukuphosa kunomthombo obanzi wezinto eziluhlaza kunye neendleko eziphantsi zemveliso. Xa kuthelekiswa nezinye iinkqubo zokubumba, ukuphosa kuneengenelo ezicacileyo.
2. Ukuphosa kukwenza isinyithi solwelo, ngoko kunokuvelisa iindawo ezingenanto okanye iinxalenye ezinemilo enzima, ngakumbi ubukhulu obuhlukeneyo kunye neenkcukacha ezinemingxuma engaphakathi entsonkothileyo.
3. Ubungakanani, ubunzima kunye nebhetshi yokuvelisa i-castings ayikhawulelwanga, eguquguqukayo ngakumbi
4. Iindleko eziphantsi zemveliso kunye nokugcinwa kwemithombo. Izinga lokusetyenziswa kwezinto liphezulu kwaye isicelo sibanzi kakhulu
5. Iipropathi zomatshini zokuphosa zibi kakhulu kune-forgings
6. Ngenxa yenani elikhulu leenkqubo zokuvelisa, izinto ezininzi, kunye nokulawula okungahambi kakuhle, umgangatho we-castings awuzinzile, kwaye iimveliso ezichithiweyo ziphezulu kakhulu.
7. Iimeko zokusebenza ezimbi
Ukusasaza okuluncedo:
1. Ukuvelisa iimilo ezintsonkothileyo, ngakumbi iindawo ezingenanto ezinemingxuma engaphakathi entsonkothileyo, efana neebhokisi ezahlukeneyo, iibhedi, iirakhi, njl.
2. Ii-castings zinokuguquguquka okubanzi kunye nokuguquguquka. Izinto ezisetyenziswa ngokuqhelekileyo zetsimbi kwishishini zingasetyenziselwa ukuphosa. Ubunzima be-castings bunokuvela kwiigram ezimbalwa ukuya kwiitoni ezingamakhulu amaninzi, kwaye ubukhulu bodonga bu malunga ne-0.5mm ukuya kwi-1m.
3. Izinto zokusa ekrwada zitshiphu kwaye ziphantsi ngexabiso
ukusilela:
1. Isakhiwo samalungu sikhululekile, iinkozo zilukhuni, kwaye iziphene ezifana ne-shrinkage cavities, i-shrinkage porosity, kunye ne-pores ziveliswa lula ngaphakathi. Ke ngoko, iipropathi ze-mechanical of castings, ngokukodwa ukuqina kwempembelelo, ziphantsi kunezo ze-forgings zento efanayo.
2. Umgangatho wokuphosa awuzinzile ngokwaneleyo.
