Using ESC technology to improve the durability of cemented carbide thread blades

Inqubo ye-ESC (Edge kanye ne-Surface conditioning) iyinqubo yokuthuthukisa (i-passivation) kanye nokupholishwa kwendawo enqenqemeni yokusika. Ngenqubo ye-ESC, amandla onqenqema lwethuluzi angathuthukiswa, isimo sokucindezelwa kwangaphezulu siyathuthukiswa, inani lobunzima obungaphezulu liyancishiswa, futhi ukuqina kwethuluzi izikhathi ezi-1 ~ 4. 

Ukugaya uwoyela wonyaka waseShayina kanye nokukhiqizwa kwamapayipi ensimbi asetshenziswa amathani angaphezu kuka-800,000, ukucutshungulwa kwepayipi lensimbi ye-petroleum kudinga ukusebenzisa inani elikhulu lama-threaded blades (izinkulungwane eziyikhulu zezingcezu / ngonyaka), ngakho ukusetshenziswa kobuchwepheshe be-ESC ukuthuthukisa ikhwalithi nokuqina kwama-threaded blades kunezinzuzo ezibalulekile zezomnotho.

1. Izici zomumo zama-thread blades angu-1 Leli phepha liwuhlobo lwe-blade yekama enamazinyo amathathu esetshenziselwa intambo yangaphandle ye-casing kawoyela, kanti i-blade yi-YT715 cemented carbide. Onqenqemeni lwezinyo ngalinye, amaphuzu ayi-11 we-A~q akhethiwe, lapho iphoyinti lika-H limelela ichopho lensingo, amaphuzu u-A no-Q amelela unqenqema lwempande, kanti u-D no-L bamele uhlangothi lonqenqema. Ekukhuliseni okuphezulu, unqenqema lwe-blade (okungukuthi ukuhlangana kobuso bangaphambili nangemuva) akuwona umugqa olula, kodwa indawo eyinkimbinkimbi. 

Ubukhali bonqenqema buboniswa iradius re. I-blade ifakwe ngomshini ukuze yakhe unqenqema lwemvelo olubukhali, njengoba kuboniswe kuMfanekiso .ububanzi bonqenqema lomumo wezinyo alufani (re=0.002~0.018mm).

Ukuze kuthuthukiswe ukuthembeka nokuzinza kwethuluzi lokusika, ukucija okunembayo konqenqema ngobuchwepheshe be-ESC kungandisa amandla onqenqema (ukwandisa kabusha), kunciphise inani lobunzima obungaphezulu (ra

2. Ubuchwepheshe be-ESC kanye ne-Vibration honing indlela ye-ESC (Edge kanye nokwelashwa kokuqina kwendawo) inqubo ngokwesimiso ingahlukaniswa ngomshini, amakhemikhali, i-electrochemical, abrasive, ukucubungula okushisayo, i-electromagnetic kanye nezinye izindlela zobuchwepheshe, njenge-brush machine honing method, i-vibration abrasive honing indlela, indlela yokuthuthukisa ukuqhunyiswa kwesihlabathi, indlela yokuqhuma kwezinhlayiyana ezihamba ngesivinini esikhulu. 

Kuleli phepha, indlela ye-vibration abrasive honing isetshenziselwa ukuqinisa indawo enqenqemeni ye-thread blade, ebonakala ngokutshalwa kwezimali okuncane kanye nezindleko eziphansi, futhi inganciphisa ngempumelelo noma iqede ukucindezeleka okusele endaweni ye-blade, ngaleyo ndlela ikhulise ukuqina kwe-blade. Umshini wokucija wokudlidliza wendabuko wakhiwe ngendlela yokudlidliza (injini, ikhamera, intwasahlobo, njll.) kanye ne-worktable, i-abrasive kusetshenziswa izinhlayiya ze-sic noma ze-alumina, i-blade kanye ne-abrasive ebhokisini ebhentshini lokusebenza, ngokusebenzisa i-blade kanye nokungqubuzana kwe-abrasive, umthelela wokwenza unqenqema ludlule. Kodwa-ke, kunzima ukuqinisekisa i-radius efanayo yonqenqema lokusika, iphutha le-radius elingaphezulu kwezinyo kanye nempande yezinyo ngu-0.02 ~ 0.09mm, okuthinta ikhwalithi yomshini kanye nempilo ephumelelayo ye-blade ene-threaded. 

Kuleli phepha, uhlobo olusha lwe-mechanical vibration honing indlela isetshenziselwa ukufaka esikhundleni sekhamera yendabuko kanye nemoto ngohlobo olusha lwe-vibration motor, i-abrasive iyingxube ye-Emery ne-boron carbide, futhi ukunyakaza okuhlobene phakathi kwe-blade ne-abrasive kuyathuthukiswa ngokusebenzisa into entsha, ukuze ingaphezulu lezinyo kanye nonqenqema lonqenqema lidlulele ngaphakathi kwe-radius yokucubungula ngaphakathi kwe-0 mm yephutha futhi kuthuthukiswe ukulawulwa kwe-0 mm. blade ukuphila ngempumelelo.
