Uhlalutyo lwenkqubo ye-drill drill bit kunye namanqaku okuphunyezwa kwayo
I-drill bit luhlobo lwesixhobo sokusika esinemilo ebhityileyo kwaye sisetyenziselwa ukucubungula imingxuma yobukhulu obahlukeneyo. Iblade inde kwaye ibhityile. Iphantsi koxinzelelo olucinezelayo kunye nokukhuhlana kwinkqubo yokubhoboza isinyithi esixineneyo, kwaye iya kumelana ne-torque ethile kunye nokuphakama Ngenxa yempembelelo yokugoba uxinzelelo kunye noxinzelelo olucinezelayo, iimeko zokusebenza zimbi kakhulu. Ngenxa yesi sizathu, abaninzi abenzi bonyango lokushisa basebenzisa Izixhobo zokufudumeza eziphakamileyo ze-IGBT kunyango lobushushu, ngethemba lokuphucula ubulukhuni bayo, ukumelana nokunxiba kunye nobomi benkonzo ukuhlangabezana neemfuno zomsebenzi.
(1) Ukuqwalasela ukuba ubushushu obuphezulu kakhulu kunye nexesha elide lokubamba kuya kukhokelela kwiinkozo ezirhabaxa ze-drill bit, i-carbides yenethiwekhi ithanda ukubonakala, i-overheating okanye i-overburning, ngoko ke kufuneka kusetyenziswe ubushushu obuphantsi kunye nexesha elifutshane lokugcina ubushushu. ixesha. Ukupholisa kwamkela ukuhlelwa okuphindaphindiweyo okanye i-austempering, injongo kukunciphisa umahluko weqondo lokushisa phakathi kwangaphakathi nangaphandle kwe-drill bit, ukunciphisa uxinzelelo lwangaphakathi, kwaye ukupholisa kwe-isothermal kuya kuguqula inxalenye ye-austenite egciniweyo ibe yi-bainite ephantsi, enokunciphisa ngokufanelekileyo. ukugqwetheka kunye nokuqhekeka, kunye nokuphucula ukusebenza kwebit drill. ubunzima.
(2) Ukolulwa komgangatho woqheliso kukusebenzisa ipleyiti yentsimbi ecaba njengomgangatho womlinganiselo, cofa isuntswana le-drill ngesandla kwaye uyiqengqe kwipleyiti ecaba, khangela umsantsa ngegeyiji yokulinganisa, kwaye ulungelelanise uguquko oludlula iplate yeplate. imfuneko. Indlela kukubethelela indawo ephantsi yesibambo. . Sebenzisa indawo eshushu yokuqondisa kwezo zingenako ukulungelelaniswa ngesandla. Kwi-drill-diameter drills, ukulungiswa okushushu kufuneka kwenziwe ngokukhawuleza emva kokucima. Ekubeni kukho i-austenite egciniweyo kunye nobunzima obuphantsi, ukulungiswa kulula kwaye iziphumo ezilungileyo ziya kufumaneka. Ukongeza, ukubola kwebhafu yetyuwa ye-drill bit nayo ingumbandela obalulekileyo ofuna ukuqwalaselwa.
(3) Ukuze kuthintelwe ukuzinziswa kwe-austenite egciniweyo, ingqalelo kufuneka ihlawulwe kwi-temperature ngexesha. Ukuqwalasela ukuba ukuguqulwa kwe-austenite egciniweyo kuqhutyelwa ngexesha lokupholisa, kufuneka kupholiswe ngokukhawuleza kwiqondo lokushisa emoyeni emva kokufudumala, kwaye emva koko kufuneka kuqhutywe ubushushu obulandelayo. Ukuze ulawule ukuguqulwa kwe-drill bit, kuyafuneka ukuba isantya sokufudumala kufuneka sikhawuleze.
(4) Kwi-drill yempembelelo, izinto eziphathekayo ziyi-40Cr, kwaye ububanzi bungaphantsi kwe-50mm. Intsimbi ejikelezileyo iyacutshungulwa kwaye yenziwe, intloko ifakwe, kunye ne-high-frequency brazed cemented cemented cemented tool bit. Imfuno yobugcisa inzima ngokubanzi, kunye nobunzima be-40-50HRC, ngoko ke izixhobo zokufudumeza eziphakamileyo ze-IGBT zingasetyenziselwa ukufudumeza kwi-840-850 ℃ ukuqinisekisa ukuba i-drill inamandla amahle kunye nokuqina.
