Iingxaki kunye nezizathu zeCarbide Cutting Tools

Izixhobo zokusika i-tungsten carbide brazed zihlala zineengxaki zokuqhafaza emva kokugqabhuka. Ngezantsi kukho ezinye zeengxaki zebraze kunye nezizathu zazo.

1. I-Tungsten i-carbide tip fractures kunye nokuqhekeka

Ezona zizathu ziphambili zokuqhekeka kunye nokuqhekeka kwi-brazing zezi zilandelayo:

A: I-angle ye-rough surface phakathi kwendawo engaphantsi kwentloko ye-cutter kunye nesiseko sentloko ye-cutter ayifanelekanga kwaye indawo yokuqhafaza incinci kakhulu, ngoko ke izinto zokuthungatha kunye ne-flux ayikwazi ukuhanjiswa ngokupheleleyo.

B:  Iilugi ze-solder ezingahambelaniyo zimfutshane kakhulu xa kuthelekiswa nobuso bebrazi, okukhokelela kuqhagamshelwano oluthe ngqo phakathi kwencam engezantsi yencam ye-carbide kunye nesiseko sesinyithi, kunye nemathiriyeli yebrazi isasazwe phakathi kwazo.

C: Amaxesha okufudumeza kunye nokupholisa akhawuleza kakhulu okanye acotha kakhulu

D: Ubushushu be-solder buphezulu kakhulu. Ekubeni i-coefficient yokwandiswa komgca we-carbide ene-cemented iphantsi kakhulu, ukuba iqondo lokushisa liphezulu kakhulu, uxinzelelo olukhulu lwe-thermal luya kuveliswa kwi-joint, edlula amandla anqabileyo e-carbide ene-cemented, eya kukhokelela ekuqhekekeni kwe-carbide ene-cemented.

2. Ibraze porosity

Ezona zizathu ziphambili zale ngxaki yokubhuqa nge pores zezi:

A: Ukuba iqondo lobushushu le-solder liphezulu kakhulu, liya kubangela ukuba i-zinc ibe namagwebu kwizinto zethebhu ye-solder

B: Ukuba ubushushu be-soldering buphantsi kakhulu, i-flux ayiyi kunyibilika ngokupheleleyo, ibangele ugwebu.

3. Incam ye-carbide iyawa

Iingxaki eziphambili ze-carbide tip ziyawa ngenxa yokuba:

A: Ukukhethwa kwempahla ye-solder ayilunganga, ayikwazi ukumanziswa ngesiseko sesinyithi, okanye indawo emanzisiweyo incinci kakhulu.

B: Ubushushu be-soldering buphantsi kakhulu, kwaye i-solder ayingeni ngokupheleleyo, okukhokelela ekunciphiseni kwamandla e-braze kunye nentloko yokusika iwa.

C: Izinto ze-solder zincinci kakhulu, kwaye amandla ayancipha

D: Ubushushu buphezulu kakhulu, kwaye inxalenye yesolder iyaphuphuma

E: Izinto ze-solder azigxininisi, okubangela ukusabalalisa okungalinganiyo kwe-solder, okwenza inxalenye ye-brazing seam yobuxoki, kunye nokungonelanga kokuqina.

Ukuba unomdla kwizixhobo zokusika i-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, UNGAQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ngasekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
