Kuongororwa kwemaitiro ekupisa kupisa drill bit uye mapoinzi ekushandisa
Chibooreso imhando yechishandiso chekucheka chine chimiro chakatetepa uye chinoshandiswa kugadzira maburi ehukuru hwakasiyana. Iyo blade yakareba uye yakatetepa. Iyo inoiswa pasi pekumanikidza kudzvinyirira uye kukwesha mukuita kudhirowa simbi dzakasimba, uye zvakare inomira imwe torque uye yakakwira Nekuda kwemhedzisiro yekukotama kushushikana uye kudzvinyirira kushushikana, mamiriro ekushanda akashata zvakanyanya. Nokuda kwechikonzero ichi, vazhinji vanogadzira kupisa kupisa vanoshandisa IGBT yakakwirira-frequency heat equipment nokuda kwekupisa kupisa, kutarisira kuvandudza kuoma kwayo, kupfeka kusagadzikana uye hupenyu hwebasa kuti uwane zvido zvebasa.
(1) Tichifunga kuti yakanyanya kupisa tembiricha uye kwenguva yakareba yekubata inotungamira kune yakakasharara tsanga dzechibooreso, network carbides inotaridzika kuoneka, kupisa kana kupisa zvakanyanya, saka tembiricha yakadzika yekupisa uye ipfupi nguva yekuchengetedza kupisa inofanira kushandiswa. nguva. Iko kutonhora kunotora akawanda magiredhi kana austempering, chinangwa ndechekudzikisa mutsauko wekushisa pakati pemukati nekunze kwechibhorani, kuderedza kushushikana kwemukati, uye iyo isothermal kutonhora inoshandura chikamu cheakachengetwa austenite kuita yakaderera bainite, iyo inogona kunyatso kudzikisa. kukanganisa uye kutsemuka, uye kuvandudza mashandiro echibhorani. kuoma.
(2) Kutwasanuka kwechibhorani kushandisa ndiro yesimbi yakati sandara sechiyero chekuyera, dzvanya chibooreso neruoko wochikungurutsira paplate rakafuratira, tarisa pakakoromoka nejeji yekunzwa, uye ruramisa deformation inodarika zvinodiwa. Iyo nzira ndeyekurova iyo yakaderera point yemubato. . Shandisa nzvimbo inopisa kutwasanudza kune izvo zvisingakwanisi kugadziriswa nemaoko. Kune madhiraini makuru-diameter, kururamisa kunopisa kunofanirwa kuitwa pakarepo mushure mekudzima. Sezvo kune akawanda akachengetwa austenite uye yakaderera kuomarara, kutwasanudza kuri nyore uye mhedzisiro yakanaka ichawanikwa. Mukuwedzera, kusvibiswa kwemunyu wekugezera kwechibhorani inyaya yakakosha zvakare inoda kutarisirwa.
(3) Kuti udzivise kudzikamiswa kweakachengetwa austenite, kutarisisa kunofanirwa kubhadharwa kune kudziya munguva. Tichifunga kuti shanduko yeaustenite yakachengetwa inoitwa panguva yekudziya kutonhora, inofanira kunyoroveswa zvishoma nezvishoma kusvika mukamuri tembiricha mumhepo mushure mekupisa kwega kwega, uye ipapo kutsva kunotevera kunofanira kuitwa. Kuti udzore deformation ye drill bit, zvinodikanwa kuti kukurumidza kwekupisa kunofanirwa kuve nekukurumidza.
(4) Kudhiraivha kwemhedzisiro, zvinhu ndeye 40Cr, uye dhayamita kazhinji iri pasi pe50mm. Simbi yakatenderedzwa inogadziriswa uye inoumbwa, musoro wakaiswa, uye yakakwirira-frequency brazed simende ye carbide tool bit. Chinodiwa chehunyanzvi ndechekuomesa, nekuoma kwe40-50HRC, saka IGBT yakakwirira-frequency yekudziisa inogona kushandiswa pakudziya pa840-850 ℃ kuve nechokwadi chekuti chibooreso chine simba rakanaka uye kuoma.
