Ukusebenzisa itekhnoloji ye-ESC ukuphucula ukuqina kwe-cemented carbide thread blades
Inkqubo ye-ESC (i-Edge kunye ne-Surface conditioning) yinkqubo yokuphucula (i-passivation) kunye ne-polish surface ye-cut cut edge. Ngenkqubo ye-ESC, amandla omgca wesixhobo anokunyuswa, imeko yoxinzelelo lwangaphezulu iphuculwe, ixabiso le-roughness ye-surface liyancitshiswa, kwaye isixhobo sihlala si-1 ~ 4 amaxesha.
Ukomba oyile wonyaka waseTshayina kunye nokuveliswa kokusetyenziswa kombhobho wentsimbi ngaphezulu kweetoni ezingama-800,000, ukusetyenzwa kombhobho wentsimbi yepetroleum kufuneka kusetyenziswe inani elikhulu leentsimbi ezinemisonto (ikhulu lamawaka amaqhekeza / ngonyaka), ngoko ke ukusetyenziswa kobuchwephesha be-ESC umgangatho kunye nokuqina kweebhleyidi ezinemisonto kuneenzuzo ezibalulekileyo zoqoqosho.
1. Iimpawu zemilo ye-1 i-thread blades Eli phepha luhlobo lwe-blade ye-comb yamazinyo amathathu esetyenziselwa intambo yangaphandle ye-oil casing, kunye ne-blade material yi-YT715 cemented carbide. Kumda wokusika wezinyo ngalinye leblade, amanqaku ali-11 e-A~q akhethiwe, apho inqaku le-H limele incam yeblade, i-A kunye ne-Q imele umda wengcambu, kwaye iD kunye ne-L zimele. icala lomphetho. Ekukhuliseni okuphezulu, umgca we-blade (oko kukuthi i-junction yangaphambili kunye nobuso obungasemva) akuwona umgca olula, kodwa ngumhlaba onzima.
Ubukhali bomphetho bubonakaliswa yiradius re. I-blade yenziwe ngomatshini ukwenza umda wendalo obukhali, njengoko kuboniswe kuMzobo.
Ukuze kuphuculwe ukuthembeka kunye nokuzinza kwesixhobo sokusika, i-honing echanekileyo yomda ngeteknoloji ye-ESC inokunyusa amandla e-edge (ukwandisa kwakhona), ukunciphisa ixabiso lobunzima bomhlaba (ra
2. Itekhnoloji ye-ESC kunye ne-Vibration honing indlela ye-ESC (Edge kunye nonyango lokuqina komhlaba) inkqubo ngokomgaqo inokwahlulwa ibe ngoomatshini, imichiza, i-electrochemical, i-abrasive, i-thermal processing, i-electromagnetic kunye nezinye iindlela zobugcisa, ezifana ne-brush machine honing method, vibration. indlela ye-abrasive honing, indlela yokuphucula ukuqhunyiswa kwesanti, indlela ye-bombardment yamasuntswana esantya esiphezulu.
Kweli phepha, i-vibration abrasive honing indlela isetyenziselwa ukomeleza umphezulu wecala le-thread blade, ebonakaliswe ngotyalo-mali oluncinci kunye neendleko eziphantsi, kwaye inokunciphisa ngokufanelekileyo okanye ukuphelisa uxinzelelo olushiyekileyo kumphezulu we-blade, ngaloo ndlela ukwandisa ukuhlala incakuba. Umatshini we-vibration honing wendabuko uqulunqwe yindlela yokungcangcazela (i-motor, i-cam, intwasahlobo, njl.) i-edge passivation. Nangona kunjalo, kunzima ukuqinisekisa i-radius efanayo yomgca wokusika, impazamo ye-radius ye-tooth top kunye nengcambu yezinyo yi-0.02 ~ 0.09mm, echaphazela umgangatho womatshini kunye nobomi obusebenzayo be-threaded blade.
Kweli phepha, uhlobo olutsha lwendlela yokungcangcazela yomatshini isetyenziselwa ukutshintsha ikhamera yemveli kunye nemoto ngohlobo olutsha lwemoto yokungcangcazela, i-abrasive ngumxube we-Emery kunye ne-boron carbide, kunye nentshukumo ehambelanayo phakathi kweblade kunye nentsimbi. i-abrasive iphuculwe ngokusebenzisa i-fixture entsha, ukwenzela ukuba umphezulu wezinyo kunye ne-radius ye-edge ye-Impazamo ilawulwa ngaphakathi kwe-0.01mm, ngaloo ndlela iphucula izinga lokupasa intambo kunye ne-blade esebenzayo ubomi.
