Chii chinonzi Trochoidal Milling
Zvigayo zvekupedzisira zvinonyanya kushandiswa kugadzira ndege, grooves uye yakaoma nzvimbo. Yakasiyana nekutendeuka, mukugadziriswa kwema grooves uye nzvimbo dzakaoma dzezvikamu izvi, nzira yekugadzira uye kusarudzwa kwekugaya zvakakoshawo. Kufanana neyakajairwa nzira yekugadzira slot, iyo arc yekubata angle yenguva imwe chete yekugadzirisa inogona kusvika pakukwirira kwe180 °, mamiriro ekupisa kupisa haana kunaka, uye tembiricha inokwira zvakanyanya panguva yekugadziriswa. Zvisinei, kana nzira yekucheka yakashandurwa kuitira kuti mucheki wekucheka atenderere kune rumwe rutivi uye anotenderera kune rumwe rutivi, kona yekuonana uye chiyero chekucheka pakushandura kunoderedzwa, simba rekucheka uye tembiricha yekucheka inoderedzwa, uye hupenyu hwekushandisa hunorebeswa. . Nokudaro, kucheka kunogona kuenderera mberi kwenguva yakareba, yakadai se (Mufananidzo 1) inonzi trochoidal milling.
Kubatsira kwayo ndeyekuti inoderedza kuoma kwekucheka uye inovimbisa hutano hwekugadzirisa. Kusarudzwa kunonzwisisika kwekucheka maparamendi kunogona kuvandudza kushanda uye kuderedza mari, kunyanya kana kugadzirisa zvakaoma-ku-muchina zvinhu zvakadai semagetsi asingasviki alloys uye yakakwirira-yakaoma zvinhu, inogona kuita basa rayo zvakanyanya, uye Iine hukuru hukuru hwekusimudzira, hunogona kuva. chikonzero nei indasitiri ichibhadhara zvakanyanya uye zvakanyanya kutarisa uye inosarudza iyo trochoidal milling nzira.
Technical zvakanakira
Iyo cycloid inodaidzwa zvakare kuti trochoid uye epicycloid yakatambanudzwa, ndiko kuti, mutsetse wepoindi kunze kana mukati medenderedzwa rinofamba apo denderedzwa rinofamba richitambanudza imwe mutsara wakatwasuka wekukunguruka usingatsvedzeri. Inogonawo kunzi refu (pfupi) cycloid. Trochoidal processing ndeye kushandisa chigayo chekupedzisira chine dhayamita diki pane groove upamhi kugadzira hafu-arc groove muchikamu chidiki chearc parutivi rwayo. Inogona kugadzirisa ma grooves akasiyana-siyana uye maburi epamusoro. Nenzira iyi, muchirevo, chigayo chekupedzisira chinogona kugadzirisa magrooves uye maprofile emhando ipi neipi yakakura kupfuura iyo, uye inogona zvakare kugadzirisa zvakatevedzana zvezvigadzirwa zviri nyore.
Nekuvandudzwa uye kushandiswa kwekombuta yenhamba yekudzora tekinoroji, nzira inodzoreka yekugaya, optimization yekucheka paramita, uye yakawanda-mativi mukana weiyo trochoidal milling iri kushandiswa uye kuiswa mukutamba zvakanyanya uye zvakanyanya. Uye yakatariswa uye kukosheswa nezvikamu zvekugadzirisa maindasitiri senge aerospace, zvekufambisa zvekushandisa uye chishandiso uye kugadzira mold. Kunyanya muindasitiri yemuchadenga, inowanzoshandiswa titanium alloy uye nickel-based heat-resistant alloy zvikamu zvine akawanda akaoma machining maitiro, anosanganisira:
Kusimba kwepamusoro kwekupisa uye kuoma kunoita kuti zviome kuti mudziyo wekucheka utakure kana kutokanganisa;
High shear simba rinoita kuti blade ive nyore kukuvadza;
Low thermal conductivity inoita kuti zviome kuti kupisa kwakanyanya kutengeserwe kunze kunzvimbo yekucheka, uko tembiricha inowanzopfuura 1000ºC, izvo zvinowedzera kupfeka kwezvishandiso;
Panguva yekugadzira, zvinhu zvinowanzobatanidzwa kune blade, zvichiita kuti pave nekuvakwa-kumucheto. Hunhu husina kunaka hwakagadzirwa nemichina;
Basa rekuomesa chiitiko che nickel-based heat-resistant alloy materials ane austenite matrix yakakomba;
Iyo carbides mu microstructure ye nickel-based heat-resistant alloys inokonzera abrasive kupfeka kwechombo;
Titanium alloys ane yakakwira makemikari kuita, uye kuita kwemakemikari kunogonawo kuwedzera kukuvadzwa uye zvichingodaro.
Aya matambudziko anogona kugadziriswa nguva dzose uye zvakanaka nerubatsiro rwe trochoidal milling tekinoroji.
Nekuda kwekuenderera mberi kwekugadzirisa kwezvishandiso zvematurusi, machira, maumbirwo ejometri, uye zvimiro, kufambira mberi nekukurumidza kwehungwaru kudzora masisitimu, matekinoroji ehurongwa, uye yakakwirira-kumhanya, yakakwirira-inoshanda multifunctional muchina maturusi, yakakwirira-kumhanya (HSC) uye yakakwirira-kugona. (HPC) kucheka kwasvikawo padanho. hurefu hutsva. High-speed machining inonyanya kufunga nezvekuvandudzwa kwekumhanya. High-effect machining haifaniri kungofunga nezvekuvandudzwa kwekucheka kukurumidza, asiwo funga kuderedza nguva yekubatsira, rationally gadzirisa zvakasiyana-siyana zvekucheka uye nzira dzekucheka, uye kuita machining emakomboni kuderedza maitiro, kuvandudza chiyero chekubvisa simbi pane imwe nguva, uye panguva imwechete wedzera hupenyu hwekushandisa uye kuderedza Mutengo, funga nezvekuchengetedzwa kwezvakatipoteredza.
tekinoroji tarisiro
Zvinoenderana nedatha yekushandiswa kweiyo trochoidal milling mune aero-injini (sezvinoratidzwa patafura pazasi), kana uchigadzira titanium alloy Ti6242, mutengo wekucheka maturusi pavhoriyamu yeyuniti inogona kuderedzwa neinosvika makumi mashanu%. Maawa emunhu anogona kudzikiswa ne63%, kudiwa kwese kwezvishandiso kunogona kudzikiswa ne72%, uye mutengo wemidziyo unogona kudzikiswa ne61%. Maawa ekushanda ekugadzirisa X17CrNi16-2 anogona kudzikiswa ne70%. Nekuda kwezviitiko zvakanaka izvi uye kubudirira, nzira yemhando yepamusoro yekugaya trochoidal yakashandiswa kune yakawanda uye yakawana kutariswa uye yakatanga kushandiswa mune mamwe minda ye micro-precision machining.
