PDC Drill Bit Welding Reference

I-PDC drill bit kufuneka igcine ubulukhuni obuphezulu, ukuqina kwempembelelo ephezulu, ukuxhathisa ukothuka okuhle kwe-thermal, kunye nokuxhathisa okulungileyo kokuhlwa. Inkqubo ephambili yokutshisa i-flame ibandakanya unyango lwangaphambili lwe-welding, ukufudumeza, ukugcinwa kobushushu, ukupholisa, kunye nonyango lwe-post-welding.

Sebenza phambi kokuba PDC bit welding

I-1: i-sandblast kwaye ucoce i-PDC cutter

2: i-sandblast kwaye ucoce umzimba we-drill bit (sula ngebhola yomqhaphu yotywala)

3: Lungiselela i-solder kunye ne-flux (ngokuqhelekileyo sisebenzisa i-solder yesilivere ye-40%)

Qaphela: i-PDC cutter kunye ne-drill bit kufuneka ingangcoliswa ngeoli

Welding of PDC cutter

I-1: Faka i-flux kwindawo apho i-PDC cutter kufuneka idityaniswe kwi-bit body

2: Beka isuntswana lomzimba kwisithando somlilo esiphakathi ukuze ufudumeze

3: Emva kokufudumeza, sebenzisa umpu womlilo ukutshisa umzimba

I-4: Nciba i-solder kwi-PDC recess kwaye uyifudumeze de i-solder inyibilike

I-5: Beka i-PDC emngxunyeni we-concave, qhubeka utshisa i-drill bit body de i-solder iyancibilika kwaye iqhube kwaye iphuphume, kwaye ngokukhawuleza ugijime kwaye ujikeleze i-PDC ngexesha lenkqubo yokuthengisa. (Injongo yokukhupha igesi kwaye wenze umphezulu we-welding ufanane ngakumbi)

I-6: Musa ukusebenzisa i-flame gun ukutshisa i-PDC cutter ngexesha lenkqubo ye-welding, ukutshisa umzimba we-bit okanye ujikeleze i-PDC, kwaye uvumele ubushushu buqhube ngokukhawuleza kwi-PDC. (Nciphisa umonakalo we-thermal wePDC)

7. Ukushisa kwe-welding kufuneka kulawulwe ngaphantsi kwe-700 ° C ngexesha lenkqubo ye-welding. Ngokuqhelekileyo yi-600 ~ 650℃.

Emva kokuba i-drill bit idityanisiwe

1: Emva kokuba i-drill idityanisiwe faka i-PDC drill bit kwindawo yokugcina ubushushu ngexesha, kwaye ubushushu be-drill buphola ngokucothayo.

2: Pholisa i-drill bit ukuya ku-50-60 °, khupha i-drill bit, i-sandblast kwaye uyipholise. khangela ngononophelo ukuba indawo ye-PDC ye-welding ifakwe ngokuqinileyo kwaye ingaba i-PDC idityanisiwe yonakele.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
