1. Sarudza zviyero zvejometri zvechombo
Paunenge uchigadzira simbi isina tsvina, iyo geometry yechikamu chekucheka chechishandiso chinofanirwa kutariswa kubva kusarudzo yerake angle uye kumashure kona. Pakusarudza iyo angle angle, zvinhu zvakaita seyenyere mbiri, kuvepo kana kusavapo kwechamfering uye iyo yakanaka uye yakaipa kona ye blade inclination inofanirwa kutariswa. Pasinei nechishandiso, hombe yerake angle inofanirwa kushandiswa paunenge uchigadzira simbi isina tsvina. Kuwedzera reke angle yechishandiso kunogona kuderedza kushorwa kunowanikwa panguva yekucheka chip uye kuchenesa. Kusarudzwa kwekona yekuchenesa hakuna kunyanya kuoma, asi haifaniri kunge yakanyanya kuduku. Kana iyo angle yekubvisa iri diki zvakanyanya, zvinokonzeresa kukweshera nepamusoro peiyo workpiece, zvichiwedzera kushata kwenzvimbo yakashongedzwa uye kukurumidza kupfeka chishandiso. Uye nekuda kwekukakavadzana kwakasimba, mhedzisiro yekuomeswa kwesimbi isina tsvina inowedzerwa; iyo angle yekubvisa chombo haifaniri kunge yakakura, yakakura, kuitira kuti wedge angle yemudziyo ideredzwe, simba rekucheka rinoderedzwa, uye kupfeka kwechigadzirwa kunowedzera. Kazhinji, kona yekuyamura inofanira kunge yakakura zvakafanira pane kana uchigadzira yakajairwa kabhoni simbi.
Sarudzo yerake angle Kubva pachikamu chekucheka chizvarwa chekupisa uye kupisa kupisa, kuwedzera kwerake angle kunogona kuderedza kutema kupisa chizvarwa, uye tembiricha yekucheka haizove yakanyanya kukwirira, asi kana iyo rake angle yakakura kwazvo, vhoriyamu yekupisa kupisa. yetipi rekushandisa ichaderera, uye tembiricha yekucheka ichapesana. Yakasimudzwa. Kudzikisa kona yerake kunogona kuvandudza kupisa kwekupisa kwemusoro wekucheka, uye tembiricha yekucheka inogona kuderera, asi kana iyo angle angle iri diki, deformation yekucheka ichave yakakomba, uye kupisa kunoitwa nekucheka hakuzobviswe nyore. . Kudzidzira kunoratidza kuti iro rake angle go=15°-20° ndiro rakanyanya kukodzera.
Pakusarudza kona yekuchenesa yekugadzira rough machining, iyo yekucheka kumucheto kwesimba rekucheka maturusi ane simba anodiwa kuti ave akakwirira, saka diki diki angle angle inofanira kusarudzwa; panguva yekupedzisa, kupfeka kwechishandiso kunonyanya kuitika munzvimbo yekucheka uye nzvimbo yeflank. Stainless simbi, chinhu chinowanzoshanda kuomesa, chine simba guru pamhando yepamusoro uye kupfeka kwezvishandiso kunokonzerwa nekukwesha kwepasi. Mhepo inonzwisisika yekuyamura inofanira kuva: kune austenitic stainless steel (pasi pe185HB), kona yekuyamura inogona kuva 6 °— -8 °; yekugadzira martensitic Stainless simbi (pamusoro pe250HB), iyo angle yekubvisa ndeye 6 ° -8 °; yemartensitic Stainless simbi (pazasi 250HB), iyo clearance angle ndeye 6° -10°.
Sarudzo ye blade inclination angle Saizi uye kwakanangana ne blade inclination angle inotarisisa gwara rekuyerera kwe chip. Sarudzo inonzwisisika yeblade inclination angle ls kazhinji -10 ° -20 °. Maturusi makuru ekurerekera maturusi anofanirwa kushandiswa kana micro-kupedzisa denderedzwa rekunze, maburi anotenderedza zvakanaka, uye ndege dzekuronga zvakanaka: ls45 ° -75 ° inofanira kushandiswa.
2. Kusarudzwa kwezvinhu zvekushandisa
Paunenge uchigadzira simbi isina tsvina, chibatiso chinofanira kunge chine simba rakakwana uye kusimba nekuda kwesimba rakakura rekucheka kuti udzivise kutaura uye deformation panguva yekucheka. Izvi zvinoda kusarudzwa kwenzvimbo yakakura yakasarudzika yemubati wemidziyo, uye kushandiswa kwezvinhu zvine simba repamusoro kugadzira chibatiso, sekushandiswa kwesimbi dzakadzimwa uye dzakadzikama makumi mana neshanu kana makumi mashanu simbi.
Zvinodiwa zvekucheka chikamu chechishandiso Paunenge uchigadzira simbi isina tsvina, zvinhu zvekucheka chikamu chechishandiso chinodiwa kuve nepamusoro kupfeka kusagadzikana uye kuchengetedza kucheka kwayo kwekucheka pane yakakwirira tembiricha. Parizvino zvinowanzoshandiswa zvinhu: high-speed simbi uye simende carbide. Nemhaka yokuti simbi yepamusoro-soro inogona kungochengetedza kushanda kwayo kwekucheka pasi pe600 ° C, haina kukodzera kucheka kwepamusoro-soro, asi yakakodzera chete kugadzirisa simbi isina tsvina panguva yakaderera. Nekuti simende carbide ine zvirinani kupisa kupisa uye kupfeka kuramba pane yakakwirira-kumhanya simbi, maturusi akagadzirwa necemented carbide zvinhu anonyanya kukodzera kucheka simbi isina tsvina.
Cemented carbide yakakamurwa kuita mapoka maviri: tungsten-cobalt alloy (YG) uye tungsten-cobalt-titanium alloy (YT). Tungsten-cobalt alloys ane kuoma kwakanaka. Zvishandiso zvakagadzirwa zvinogona kushandisa hombe reke angle uye inopinza mupendero kukuya. Iwo machipisi ari nyore kukanganisa panguva yekucheka, uye kucheka kuri brisk. Machipisi haasi nyore kunamatira kune chishandiso. Muchiitiko ichi, zvakanyanya kukodzera kugadzirisa simbi isina tsvina ne tungsten-cobalt alloy. Kunyanya mukugadzira kwakashata uye kucheka kwepakati nekudengenyeka kukuru, tungsten-cobalt alloy blades inofanira kushandiswa. Haina kuoma uye brittle se tungsten-cobalt-titanium alloy, haisi nyore kurodza, uye iri nyore chip. Tungsten-cobalt-titanium alloy ine kuomarara kwakatsvuka zviri nani uye inoramba kupera kupfuura tungsten-cobalt alloy pasi pemamiriro ekushisa kwepamusoro, asi yakanyanya brittle, isingamirire kukanganiswa uye kuzununguka, uye inowanzoshandiswa sechombo chesimbi isina tsvina. kutendeuka.
Kuita kwekucheka kwechigadzirwa chemidziyo kune chekuita nekusimba uye kugadzirwa kwechishandiso, uye kugadzirwa kwechigadzirwa chemidziyo kunokanganisa kugadzirwa uye kurodza kunaka kwechishandiso pachacho. Zvinokurudzirwa kusarudza maturusi emidziyo ane kuomarara kwepamusoro, yakanaka adhesion kuramba uye kuoma, senge YG simende carbide, zviri nani kusashandisa YT simende carbide, kunyanya kana uchigadzira 1Gr18Ni9Ti austenitic simbi isina tsvina, iwe unofanirwa kudzivirira zvachose kushandisa YT hard alloy Alloy. , nekuti titanium (Ti) musimbi isina tsvina uye Ti iri muYT-mhando yecemented carbide inogadzira hukama, machipisi anogona kubvisa nyore Ti mune alloy, iyo inosimudzira kuwedzera chishandiso kupfeka. Kugadzirwa kwemaitiro kunoratidza kuti kushandiswa kweYG532, YG813 uye YW2 mamakisi matatu ezvigadzirwa kugadzira simbi isina tsvina ine yakanaka yekugadzirisa maitiro.
3. Kusarudzwa kwehuwandu hwekucheka
Kuti udzvinyirire chizvarwa cheakavakirwa-kumusoro edge uye spurs spurs uye kuvandudza mhando yepamusoro, kana uchigadziriswa necemented carbide maturusi, iyo yekucheka yakadzikira zvishoma pane iyo yekushandura general kabhoni simbi workpieces, kunyanya kumhanya kwekucheka hakufanirwe kunge kwakanyanyisa. kumusoro, kumhanya kwekucheka kunowanzo kukurudzirwa Vc=60——80m/min, kudzika kwekucheka kuri ap=4——7mm, uye chiyero chekudya f=0.15——0.6mm/r.
4. Zvinodiwa zvehupamhi hwepamusoro hwechikamu chekucheka chechishandiso
Kuvandudza kupedzisa kwepamusoro kwechikamu chekucheka chechishandiso kunogona kuderedza kuramba kana machipisi akapetwa uye kugadzirisa kusimba kwechishandiso. Kuenzaniswa nekugadzirisa zvakajairwa kabhoni simbi, kana uchigadzira simbi isina tsvina, huwandu hwekucheka hunofanira kudzikiswa zvakafanira kuti kunonoke kupfeka kwemidziyo; panguva imwecheteyo, kutonhora kwakakodzera uye mafuta ekuzora kunofanira kusarudzwa kuderedza kupisa kwekucheka uye simba rekucheka panguva yekucheka, uye kuwedzera hupenyu hwebasa rechishandiso.
