Masinyaniseke, xa uninzi lwabantu lusiva 'imvula eyenza lukhuni intsimbi engenastainless', bacinga ngegorha eligcina idatha - 17-4PH, mhlawumbi 15-5PH, kunye naloo manani anika umdla wemveliso. Inyani kumgangatho wevenkile, ngakumbi kwisamente entsonkothileyo kunye nezinto ezenziwe ngoomatshini, lirhamncwa elahlukileyo. Ayikokubetha nje inani lobulukhuni; imalunga nokulawula umdaniso phakathi konyango lwesisombululo, umjikelo wokwaluphala, kunye nokugqwetheka okungenakuphepheka okuza nayo, lonke ixesha le nxalenye idla ngokuba yinto entsonkothileyo, ebhityileyo yotyalo-mali. Kulapho ulwazi lwenyani, kunye nemigibe eqhelekileyo, ihlala khona.
Umtsalane kunye neNyaniso yamaBanga e-PH
Sifumana imibuzo emininzi ye-17-4PH. Kukuhamba. Abathengi babona i-1300 MPa tensile kwaye bacinga ukuba yindawo yokulahla nayiphi na imfuno yamandla aphezulu. Kodwa ndibone iiprojekthi zikhubeka ngaphandle kwesango kuba khange bayithathele ingqalelo imeko. Ngaba siqala ngesitokhwe sebha, ukubunjwa, okanye ukuphosa? Kwinkampani efana neyethu, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), apho utyalo mali yinkqubo engundoqo, ibali liqala ngekhemistri enyibilikayo kunye nemeko yokuphosa. I-homogeneity yesisombululo se-annealed state ngaphambi kokuba sicinge ngokuguga kubalulekile. I-casting inokuba ne-micro-yantlukwano ukuba ibar eyenziweyo ayinayo, nto leyo inokukhokelela ekuphenduleni okungahambelaniyo kamva.
Emva koko kukho ukulandelelana komatshini. Ngaba umatshini ukwimeko ephathwe ngesisombululo (ethambileyo, kulula kwizixhobo) kwaye emva koko ubudala? Okanye ngaba uyaguga kuqala kwaye uzame ukwenza umatshini we-40+ HRC imathiriyeli? Eyangaphambili iqhele ukuba krelekrele, kodwa kuya kufuneka ubhake kwi-dimensional shift ukusuka ebudaleni ukuya ekunyamezeleni kwakho. Oku sikufunde kabuhlungu kwangethuba ngomzimba wevalvu. Yenziwe kakuhle kwiMeko A, yamdala, kwaye yafumanisa ukuba iidayamitha ezibalulekileyo ziqiniswe ngaphaya kokucaciswa. Kuye kwafuneka ukuba isisombululo siphinde siphathe yonke into kunye nomatshini kwakhona, esisifundo esixabisa kakhulu kwibhayisekile eshushu.
Ikunyanzela ukuba ucinge ngokugqibeleleyo. Ukhetho alukho nje insimbi engenasici, yinkqubo yenkqubo: ukuphosa ingqibelelo -> isisombululo se-anneal uniform -> isibonelelo se-stock pre-machining -> ukuguga okulawulwayo -> ukugqitywa kokugqibela. Ukungabikho kwekhonkco kwaphula ikhonkco. Yiyo loo nto kwiindawo ezithembekileyo eziphezulu, sihlala sisebenzisana neqela lobunjineli bomthengi ukusuka kwinqanaba leCAD, hayi nje xa iRFQ ifika.
Imeko ye-H900 vs. H1150: Akuyona nje iqondo lokushisa
Iimpawu zokuguga ezisemgangathweni (H900, H1025, H1150) ngamanqaku okuqalisa, hayi ivangeli. I-H900 ikunika amandla aphezulu kodwa ukuqina okusezantsi. Kwicandelo lesixhobo sokumisa esisebenze kulo, i-spec ibize i-H900. Kodwa ngexesha leprototyping, iimvavanyo zeCharpy kwiqondo lobushushu eliphantsi lalingumda. Saba nengxoxo ende kunye ne-metallurgist yomthengi. Ngaba sinokufikelela kwidiphu yamandla kancinane ukwenzela ukomelela kokwaphuka okungcono? Siqhube ibhetshi kwi-H925 kwaye emva koko i-H950, ukuvavanya ukuqina kunye nefuthe. I-H950 isinike ibhalansi elungileyo - amandla ayesengaphezulu koyilo oluncinci, kodwa ixabiso lempembelelo liye latsiba. Yavunywa njengomjikelo wokuguga ongomnye. I-database ayisixelelanga oko; uvavanyo olulawulwayo kunye nesigwebo sobunjineli senze.
Kulapho i-30-plus iminyaka ekuphoseni kunye CNC Machining uyahlawula. Uhlakulela ukuvakalelwa kwindlela izinto ezihamba ngayo. Ukuqina kwemvula i-alloys, ngexesha lokuguga, musa nje ukuba nzima; bafumana utshintsho olufihlakeleyo lobukhulu. Kwindlu entsonkothileyo, engalinganiyo yotyalo-mali, ayifani. Siye saqalisa ukusebenzisa iikhuphoni zovavanyo lwedini eziphoswe kuthululo olufanayo, zincanyathiselwe kwiindawo ezibalulekileyo zenxalenye ngamasango amancinci. Siguga yonke indibano, emva koko sinqumle amakhuphoni ukuze sibe lukhuni kunye neetshekhi ezinobungakanani. Linyathelo elongezelelweyo, kodwa imephu yokuphendula ukwaluphala kwinxalenye yejometri, igcina intlungu kamva.
Kwaye makhe sithethe malunga nokusebenza kwakhona. Kuthekani ukuba inxalenye indala kwaye kufuneka ilungiswe? Liphupha elibi. Ubushushu obuvela kwi-welding ngaphezulu-kobudala be-HAZ, ukudala indawo ethambileyo. Ngokuqhelekileyo kufuneka ubuyele kwisisombululo esipheleleyo se-anneal, esinokujija inxalenye, emva koko umatshini uphinde uneminyaka yobudala. Ngamanye amaxesha, ukonga ngakumbi ukuyilahla. Le yingongoma ephambili esiyigxininisayo ngexesha lokuphononongwa koyilo QSY: ukuba weldability yinto enokwenzeka kwixesha elizayo, mhlawumbi ibakala elahlukileyo intsimbi engenasici kungcono, nokuba amandla okuqala asezantsi. Umjikelo wobomi uwonke ubalulekile.
I-Special Alloys Overlap: PH vs. Maraging
Le yi tangent enomdla. Sikwasebenza kunye ialloys ezikhethekileyo njengeentsimbi zokurhweba. Abathengi ngamanye amaxesha bababhidanisa nge-PH engenasici. Zombini zomeleza ngemvula, kodwa i-maraging steels i-iron-nickel ene-cobalt, i-molybdenum, i-titanium - akukho chromium yokumelana nokubola. Zisisilwanyana esahlukileyo. Unyango lwabo lwesisombululo yi-austenitize elula kunye nomoya opholileyo, okwenza i-martensite ethambileyo. Ukuguga emva koko kukhokelela kwi-intermetallics. Ugqweso luhlala lusezantsi kune-PH engenasici, eyinzuzo enkulu kumatshini omde, obhityileyo.
Ndikhumbula iprojekthi yokuchaneka okuphezulu kwe-actuator shaft. Ukupasa kokuqala kwakune-15-5PH. Emva kokwaluphala, ukuma ngokuthe tye kwaphuma. Siphinde sayilungisa ngoomatshini abachanekileyo, kodwa ayilunganga. Sicebise i-C250 maraging steel njengenye indlela. Ukumelana nomhlwa kwakungafuneki (yayikwindawo evaliweyo, ethambisayo). Indlela yokutyhutyha yasinika amandla, unyango olulula lobushushu kunye nokuphazamiseka okuncinci, kunye nobuchule obugqwesileyo kwisimo esinesisombululo. Ibilingana ngcono. Imalunga nokuba ne-palette ye-material kunye namava okwazi ukuba unganyathela nini ngaphandle kwebhokisi ye-stainless standard.
Olu hlobo lokudluliselwa kwepoleni kolwazi lubalulekile. Ukusebenza kunye ialloys esekwe nickel kunye ne-cobalt alloys ikufundisa okuninzi malunga ne-kinetics yemvula kunye novakalelo lonyango lobushushu. Olo lwazi lubuyela emva kwindlela esiwaphatha ngayo amabanga e-PH axhaphake kakhulu. Idityanisiwe yonke.
UMatshini we-CNC: Izixhobo kunye noMdaniso oPholisayo
Ukucoca i-PH engenasici, ngakumbi kwimeko yobudala, kulapho utshisa khona ngokusebenzisa uhlahlo lwabiwo-mali lwezixhobo ukuba awulumkanga. I-abrasive kwaye isebenza-nzima. Siye sazinza kwimithetho embalwa enzima. Okokuqala, ukuseta eziqinileyo. Nayiphi na incoko iya kusebenza ngoko nangoko-yenza nzima umphezulu, yenze isihogo esilandelayo sidlule. Okwesibini, i-ceramic okanye i-advanced carbide ifaka iijiyometri ezibukhali, ezintle. Asibaleki intsimbi enesantya esiphezulu apha. Ukupholisa akuxoxiswana, kwaye kufuneka ibe yi-lubricity ephezulu, uhlobo lokwenziwa, olukhukula ngesisa. Injongo kukutsala ubushushu ngaphandle kunye ne-chip, ungabuvumeli ukuba bungene kwindawo kwaye kunokwenzeka ukuba bugqithise iminyaka.
Ukwemba imingxuma enzulu kulucelomngeni olukhethekileyo. Ukugrumba iPeck kuyimfuneko, kunye nokurhoxa ngokupheleleyo ukususa iitshiphusi kunye nokupholisa iiflethi. Sonakalise izinto ezimbalwa ezibiza imali eninzi kwangethuba ngokuvumela iitshiphusi ukuba zibe nenyongo kwaye zidibanise kwi-drill, eyathi emva koko yagqabhuka emngxunyeni. Ngoku, iinkqubo zethu ze-CNC zezi zixhobo zinesondlo esigcinayo/iitafile zesantya, ezakhiwe kwiminyaka yovavanyo kunye neempazamo. Idatha kwiwebhusayithi yabo, https://www.tsingtaocnc.com, uthetha ngezakhono, kodwa amandla okwenyani yilayibrari yeparameter kubalawuli bethu boomatshini kunye namava abadwelisi bethu benkqubo eyazi ukuba bayigqithise nini.
Ukugqitywa komphezulu kubaluleke kakhulu. Umphezulu womatshini orhabaxa kwi-alloy ye-PH unokuba luxinzelelo loxinzelelo kunye nesiza sokuqalisa umhlwa. Sihlala sichaza ipasi lokugqibela elinokufakwa okuzinikeleyo kokugqibezela okanye nokusila okulula/ukusebenza kokupholisha kwindawo yokutywina. Yongeza iindleko, kodwa ngenxalenye kwindawo eyingozi, enoxinzelelo oluphezulu, yi-inshurensi.
Ukujonga Ngasemva kwaye Ukuqhubela Phambili
Ke, kusishiya phi ke oku imvula yenza lukhuni intsimbi engatyiwayo? Lusapho olumangalisayo lwemathiriyeli, kodwa lufuna intlonipho kunye nendlela yeenkqubo. Asiyonto yorhwebo. Ixabiso eliziswa ngumthengisi alikho nje ekunyibilikeni nasekugaleleni okanye ekuqhubeni umatshini we-CNC; kukuhlanganisa loo manyathelo kunye nesinyithi.
Nge QSY, iminyaka engamashumi amathathu iqokobhe ngundo ukuphosa, utyalo-mali, kunye nokwenza oomatshini kuthetha ukuba sizibonile ezi ngxaki ngaphambili. Siye sajija iinxalenye, izixhobo ezaphukileyo, kwaye sathumela iikhuphoni zovavanyo ukufumana ijiko lokuguga lilungile. Loo nkumbulo yeziko yiyona nto ethintela loo miba ukuba iqhubeke kwiprojekthi elandelayo. Ivumela ukuba sikhokele abathengi kude nemigibe enokubakho - njengokuchaza ukuguga kwe-H900 kwindawo enkulu, encinci yecandelo eliya kuphazamisa ngokungalawulekiyo, okanye ukucwangcisa inyathelo le-welding emva kokunyanga kobushushu bokugqibela.
Ikamva, ndiyacinga, likumanyano oluqina ngakumbi. Mhlawumbi usebenzisa ukulinganisa ukuqikelela ukugqwetheka kokwaluphala okusekwe kwijiyometri yokuphosa, okanye ukusetyenziswa okubanzi ngakumbi kokujonga inkqubo ngexesha lomatshini wokubona ukunxitywa kwesixhobo ngaphambi kokuba kuchaphazele ingqibelelo yomphezulu. Kodwa undoqo uya kuhlala: ukuqonda ukuba i-PH ingenasici yinkqubo, hayi nje into. Awuthengi ibha yentsimbi; uthenga ufezekiso olunempumelelo lolandelelwano oluthambileyo lobushushu kunye noomatshini. Kwaye ukufumana olo landelelwano ngokufanelekileyo kuko okwahlula inxalenye esebenzayo ukusuka kwethembekileyo.
