PDC Drill Bit Vuam Reference

PDC laum me ntsis yuav tsum muaj lub siab hardness, muaj kev cuam tshuam toughness, zoo thermal shock kuj, thiab zoo corrosion kuj. Cov txheej txheem tseem ceeb ntawm nplaim taws brazing suav nrog kev kho ua ntej vuam, cua sov, txuag hluav taws xob, cua txias, thiab kev kho tom qab vuam.

Ua haujlwm ua ntej PDC me ntsis vuam

1: sandblast thiab ntxuav PDC cutter

2: sandblast thiab ntxuav lub laum me ntsis lub cev (so nrog cawv paj rwb pob)

3: Npaj solder thiab flux (feem ntau peb siv 40% nyiaj solder)

Lus Cim: PDC cutter thiab laum me ntsis yuav tsum tsis txhob stained nrog roj

Vuam ntawm PDC cutter

1: Siv flux rau qhov chaw uas PDC cutter yuav tsum tau welded rau ntawm lub cev me ntsis

2: Muab lub cev me me rau hauv qhov nruab nrab zaus qhov cub kom preheat

3: Tom qab preheating, siv cov nplaim taws kom sov lub cev me ntsis

4: Dissolve lub solder nyob rau hauv PDC recess thiab kub kom txog thaum lub solder melts

5: Muab PDC tso rau hauv qhov concave, txuas ntxiv kom sov lub laum lub cev kom txog rau thaum lub solder yog yaj thiab ntws thiab ntws, thiab maj mam khiav thiab tig PDC thaum lub sij hawm soldering. (Lub hom phiaj yog kom tso pa tawm thiab ua kom qhov chaw vuam zoo sib xws)

6: Tsis txhob siv cov nplaim taws los ua kom sov PDC cutter thaum lub sij hawm vuam, ua kom sov lub cev me ntsis los yog nyob ib ncig ntawm PDC, thiab cia cov cua sov maj mam ua rau PDC. (Kev txo qis thermal puas ntawm PDC)

7. Lub vuam kub yuav tsum tau tswj hauv qab 700 ° C thaum lub sij hawm vuam txheej txheem. Feem ntau yog 600 ~ 650 ℃.

Tom qab lub laum me ntsis yog welded

1: Tom qab lub laum yog welded muab PDC laum me ntsis rau hauv qhov chaw txuag hluav taws xob nyob rau lub sijhawm, thiab qhov kub ntawm qhov xyaum yog maj mam txias.

2: Txias lub laum me ntsis rau 50-60 °, tshem tawm lub laum me ntsis, sandblast thiab polish nws. Ua tib zoo xyuas seb PDC qhov chaw vuam puas yog welded khov kho thiab seb PDC puas welded puas.
