Ireferensi ye-PDC Drill Bit Welding

I-PDC drill bit kumele igcine ubulukhuni obuphezulu, ukuqina komthelela omkhulu, ukumelana nokushaqeka okuhle kokushisayo, nokumelana nokugqwala okuhle. Inqubo eyinhloko yokushisa ilangabi ihlanganisa ukwelashwa kwangaphambili kokushisela, ukufudumeza, ukugcinwa kokushisa, ukupholisa, nokwelashwa kwangemuva kokushisela.

Sebenza ngaphambi kokushisela kancane kwe-PDC

1: i-sandblast bese uhlanza i-PDC cutter

2: i-sandblast bese uhlanza umzimba we-drill bit (sula ngebhola likakotini lotshwala)

3: Lungiselela i-solder kanye ne-flux (ngokuvamile sisebenzisa i-solder yesiliva engu-40%)

Qaphela: i-PDC cutter kanye ne-drill bit akumele igcotshwe ngamafutha

Ukushiswa kwe-PDC cutter

1: Faka i-flux endaweni lapho i-PDC cutter idinga ukushiselwa khona emzimbeni omncane

2: Faka umzimba omncane esithandweni somlilo esimaphakathi ukuze ushise kuqala

3: Ngemuva kokushisa, sebenzisa isibhamu somlilo ukushisa umzimba omncane

4: Chaza i-solder ku-PDC recess futhi uyishise kuze kube yilapho i-solder incibilika

I-5: Faka i-PDC emgodini we-concave, qhubeka nokushisa umzimba we-drill bit kuze kube yilapho i-solder incibilika futhi igeleza futhi igcwale, futhi ugijime kancane futhi ujikeleze i-PDC ngesikhathi senqubo yokuhlanganisa. (Inhloso ukukhipha igesi nokwenza indawo yokushisela ifane kakhulu)

I-6: Ungasebenzisi isibhamu somlilo ukushisa i-PDC cutter ngesikhathi senqubo yokushisela, ukushisa umzimba omncane noma eduze kwe-PDC, futhi uvumele ukushisa kuqhube kancane ku-PDC. (Nciphisa umonakalo oshisayo we-PDC)

7. Ukushisa kwe-welding kumele kulawulwe ngaphansi kuka-700 ° C ngesikhathi senqubo yokushisela. Ngokuvamile ngu-600 ~ 650 ℃.

Ngemuva kokuthi i-drill bit ishiselwe

1: Ngemva kokuba i-drill isishiselwe faka i-PDC yokuprakthiza kancane endaweni yokugcina ukushisa ngesikhathi, futhi izinga lokushisa lomshini wokubhola lipholiswa kancane kancane.

2: Pholisa i-drill bit ibe ngu-50-60°, khipha i-drill bit, i-sandblast futhi uyipholise. hlola ngokucophelela ukuthi indawo ye-PDC yokushisela i-welded ngokuqinile futhi ukuthi i-PDC ihlanganisiwe yonakele yini.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
