Ukusebenza okubandayo kwensimbi kusetshenziselwa ukugxila, ukuncipha, ukwakha, ukugoqa, ukukhishwa okubandayo, ukukhishwa okubandayo, ukubulawa kwempuphu, njll. Kudinga ukuqina okuphezulu, ukumelana nokwanele. Ngokuvamile ihlukaniswe izigaba ezimbili: uhlobo olujwayelekile nohlobo olukhethekile. Isibonelo, umsebenzi obandayo onenhloso yokufa e-United States uvame ukufaka amamaki amane wensimbi: 01, A2, D2, ne-D3. Ukuqhathaniswa kwamamaki ensimbi womsebenzi obandayo wenhloso yonke i-ally ally ensimbi emazweni ahlukahlukene kukhonjisiwe ku-SK Serven Tool Steel, kanye ne-9 SKHME CORD CARES STEMES, kanye ne-9 SKHMO Speed Speents, amamaki wensimbi angama-24. Izinga lensimbi yensimbi ye-GB / T12992000 ahlanganisa amathuluzi ensimbi ayizinsimbi eziyi-11, akha uchungechunge oluphelele. Ngoshintsho ekusebenzeni kwezobuchwepheshe, izinto ezisetshenzisiwe nezidingo zokubumba, uchungechunge lwangempela oluyisisekelo alukwazi ukufeza izidingo. I-Japan Steel Mills neThuluzi Elikhulu LaseYurophu kanye nabakhiqizi bensimbi ye-Die bathuthukise umsebenzi obandayo onobuchule obukhona, futhi kancane kancane kwakhiwa umsebenzi obandayo obandayo wensimbi, ukuthuthukiswa komsebenzi obandayo wokufa kwensimbi nakho ukuqondiswa komsebenzi obandayo.
Umoya ophansi we-alloy uqeda umsebenzi obandayo ufa insimbi
Ngokuthuthukiswa kobuchwepheshe bokwelashwa okushisa, ikakhulukazi ukusetshenziswa okubanzi kobuchwepheshe bokuqedwa kwe-vacuum embonini yokubumba, ukuze kuncishiswe ukucima ukoma, ama-all-alloy acijile air-junch airled air-denched air airled air air-junch airled air air air-denched air. Lolu hlobo lwensimbi ludinga ukuqina okuhle kanye nokwelashwa okushisa kunokuguquguquka okuncane, amandla amahle nokuqina komzimba. Yize umsebenzi ozobandayo we-alloy onamakhaza ajwayelekile wensimbi (njenge-D2, A2) unokukhalipha okuhle, unokuqukethwe okuphezulu kwe-alloy futhi kuyabiza. Ngakho-ke, ezinye zensimbi ephansi ephansi ziye zakhiwa ekhaya nakwamanye amazwe. Lolu hlobo lwensimbi ngokuvamile luqukethe izinto ze-alloy etemementr Cr ne-MN alloy izinto zokuthuthukisa ukuqina. Okuqukethwe okuphelele kwezinto ze-alloy ngokuvamile <5%. Ilungele ukukhiqiza izingxenye ezinengqondo ezinembile ngamabhethri amancane okukhiqiza. Isikhunta esiyinkimbinkimbi. Amamaki ensimbi abamele afaka i-A6 e-United States, acd37 aqhamuka ezinsimbi ze-Hitachi, G04 kusuka ku-Dado Special Special, njll. Ingasetshenziswa ukwenza ukuncipha okubandayo kufa okuthambekele ekuphumeni nasekuphazamisekeni. Impilo Ephakeme Yesevisi.
Ilangabi liqede insimbi yokubumba
Ukuze unciphise umjikelezo wokukhiqiza isikhunta, yenza lula inqubo yokwelashwa kokushisa, gcina amandla bese wehlisa izindleko zokukhiqiza zesikhunta. IJapan ithuthukise umsebenzi okhethekile onamakhaza wokufa kwezidingo eziguqukayo zelangabi. Okujwayelekile kufaka phakathi i-Aichi Steel's SX105V (7CRSIMNMOV), SX4 (CR8), HMD1, i-DMD1 yensimbi yensimbi yensimbi, njll. I-China yathuthukisa i-7CR7SIMNNMMOV. Lolu hlobo lwensimbi lungasetshenziselwa ukushisa ibala noma ezinye izingxenye zesikhunta usebenzisa isibhamu se-oxyacetylene fafaza isibhamu noma ezinye izithombi ngemuva kokuthi isikhunta sicutshunguliwe bese siphoqeleka umoya. Ngokuvamile, ingasetshenziswa ngqo ngemuva kokucima. Ngenxa yenqubo yayo elula, kusetshenziswa kabanzi eJapan. Uhlobo lwensimbi omele lolu hlobo lwensimbi lungu-7CRSIMNMOV, onobuqili obuhle. Lapho i-φ80mm Insimbi icishiwe uwoyela, ubulukhuni ebangeni le-30mm ukusuka ebusweni bangafinyelela ku-60hrc. Umehluko wobulukhuni phakathi komgogodla futhi ingaphezulu yi-3HRC. Lapho ilangabi lijuluka, ngemuva kokuqala ngo-180 ~ 200 ° C futhi lifudumeza liye ku-900-1000 ° C ngokucishwa ngesibhamu sokufafaza, ubulukhuni bungafinyelela ngaphezulu kuka-60hrc kanye nesendlalelo esilukhuni ngaphezulu kwe-1.5mm esingatholakala.
Ukuqina okuphezulu, ukumelana okuphezulu kokuphikisana nomsebenzi obandayo wensimbi
Ukuze uthuthukise ubulukhuni bomsebenzi obandayo wokufa kwensimbi futhi unciphise ukumelana kwensimbi, ezinye izinkampani ezinkulu zokukhiqiza zensimbi yakwamanye amazwe zithuthukise ngochungechunge lokusebenza okubandayo kokudla okubandayo nokuphikisana okuphezulu. Lolu hlobo lwensimbi ngokuvamile luqukethe cishe i-1% Carbon no-8% CR. Ngokungeziwe kwe-M, v, nokunye kanye nezinye izinto ezengeziwe, ama-carbusis awo alungile, asatshalaliswa ngokulinganayo, futhi ubunzima bawo buphakeme kakhulu kunaleso sensimbi ye-CR12, kanti ukumelana kwayo kufana. . Ubulukhuni babo, amandla aguqukayo, amandla okukhathala nokuqina kokuqhekeka kuphakeme, futhi ukuzinza kwawo okulwa nomoya kuphakeme kakhulu kunensimbi ye-CRL2 yohlobo lwensimbi. Zilungele ama-punches asheshe asheshe nezipuni ezinama-multi amaningi. Izinhlobo zensimbi ezimele zalolu hlobo lwensimbi yi-DC53 yaseJapan enokuqukethwe okuphansi kwe-v kanye ne-cru-grat nge-High v okuqukethwe. I-DC53 icinywe ngo-1020-1040 ° C kanti ubunzima bungafinyelela ku-62-63hrc ngemuva kokupholisa komoya. Kungashukunyiswa emazingeni okushisa aphansi (180 ~ 200 ℃) kanye nokushisa okuphezulu okushisa okuphezulu (500 ~ 550 ℃), ukuqina kwalo kungaphakamisa izikhathi ezi-1 kune-D2, futhi ukusebenza kwayo kokukhathala kuphakeme kunama-D2% aphezulu kune-D2; Ngemuva kokugqoka kwe-cru-graild futhi ugoqa, kufakwa ngaphakathi futhi kuhloliswe futhi kufakwe ku-850-870 ℃. Ngaphansi kwama-30 ℃ / ihora, kuphoqelelwe ku-650 ℃ futhi kwakhishwa, ubulukhuni bungafinyelela ku-225-255hb, ubulukhuni bungatholakala ku-630
I-Base Steel (Insimbi Eshesha Kakhulu)
Insimbi eshesha kakhulu isetshenziswe kabanzi phesheya izokwakha ukusebenza okuphezulu, isikhunta esidala sokudla okubandayo ngenxa yokumelana nokuqina kwayo okuhle kakhulu nokuqina okubomvu, njenge-General General General Standard ephezulu yensimbi SKH51 (w6mo5cr4v2). Ukuze uzivumelanise nezidingo zesikhunta, ubunzima buvame ukuthuthuka ngokunciphisa ubulukhuni obucijile, obucima ubulukhuni noma ukunciphisa ukuqukethwe kwekhabhoni ngensimbi ephezulu. I-Matrix Steel ithuthukiswe ngensimbi esheshayo, futhi ukwakheka kwayo kwamakhemikhali kulingana nokwakhiwa kwe-matrix yensimbi ephezulu ngemuva kokucima. Ngakho-ke, inani le-carbides esele ngemuva kokucimasha lincane futhi lisatshalaliswa ngokulinganayo, elithuthukisa kakhulu ubunzima bensimbi uma kuqhathaniswa nensimbi enesivinini esikhulu. I-United States neJapan bafunda ama-steel amabanga anamabanga vascoma, i-vascomatrix1 ne-mod2 ekuqaleni kweminyaka yo-1970. Muva nje, i-DRM1, i-DRM2, i-DRM3, njll. Ngokuvamile okusetshenziselwa isikhunta somsebenzi obandayo esidinga ubulukhuni obuphakeme kanye nokuqina okulwa nomoya. I-China iphinde yakha amanye ama-steel, njenge-65nb (65cr4w3mo2vnb), 65w8cr4vti, 65cr5mo3w2VSITI kanye nezinye izinsimbi. Lolu hlobo lwensimbi lunamandla amahle nokuqina futhi lusetshenziswa kabanzi ekuchithekeni okubandayo, amasondo okugoqa ama-pure, amasondo awohlokayo, kufa umxhwele, afe kufa njengokufa okufudumele kufa.
I-powder metalluur mold insimbi
I-LEDB-Type High-Alloy Yough-Alloy Umsebenzi Obandayo Wensimbi Ekhiqizwe ngezinqubo ezijwayelekile, ikakhulukazi izinto ezinkulu, ine-carbides ye-eutectic kanye nokusatshalaliswa okujulile, okunciphisa kakhulu ukuncipha kwensimbi, okugaya kanye ne-isotropy yensimbi. Eminyakeni yamuva nje, izinkampani ezinkulu zensimbi ezikhethekile zakwamanye amazwe ezikhiqiza ithuluzi nensimbi yokufa zigxile ekuthuthukiseni uchungechunge lwensimbi yensimbi ye-powder metallurgy ne-high-alloy die, okuholele ekuthuthukisweni okusheshayo kwalolu hlobo lwensimbi. Usebenzisa inqubo ye-powder metallurgy, i-athomu yensimbi powtha ipholile ngokushesha futhi ama-carbides akhiwa alungile futhi afana, athuthukisa kakhulu ubunzima, ukugaya kanye ne-isotropy yezinto ezibumbayo. Ngenxa yale nqubo ekhethekile yokukhiqiza, i-carbusides ihamba kahle futhi iyunifomu, futhi umsebenzi wokugaya nokugaya kuyathuthukiswa, okuvunyelwa okuqukethwe okuphezulu kwe-carbon nokuthola uchungechunge lwezinhlobo ezintsha zensimbi. Isibonelo, uchungechunge lwe-DEX's DEX's DEX (Dex40, dex60, dex80, njll.), Uchungechunge lwe-Hitachi Metal's Hap, uchungechunge lwe-Fasdeholm's Favelis lwe-ASP, kanye ne-American's ASP's Powre Plaven Metallurgy ne-Die Scasfible Company, kanye ne-American's ASP yenkampani ye-powder metallurgy kanye nensimbi yensimbi yathuthuka ngokushesha. Ukwakha uchungechunge lwama-powder metallurgy steel efana ne-CPMLV, i-CPM3V, i-CPMLOV, i-CPM15V, njll.
