Iintonga zebrazing ezisetyenziselwa ukuwelda iPDC cutter

Yintoni na iintsimbi zokugquma

I-brazing rods zintsimbi zokuzalisa ezisetyenziswa kwinkqubo yokubrawuza, eyindlela yokudibanisa esebenzisa ubushushu kunye nemathiriyeli yokuzalisa ukudibanisa amaqhekeza esinyithi amabini nangaphezulu., njengentsimbi ukuya kwintsimbi okanye ubhedu ukuya kobhedu. Iintsimbi zokubethela ngokuqhelekileyo zenziwe nge-alloy yensimbi enendawo ephantsi yokunyibilika kunesiseko sesinyithi esidityanisiweyo. Iindidi eziqhelekileyo zeentsimbi zokubethela ziquka ubhedu, ubhedu, isilivere, kunye ne-aluminium alloys. Uhlobo oluthile lwentonga yokuqhafaza esetyenzisiweyo ixhomekeke kwizinto ezidityanisiweyo kunye neempawu ezifunwayo zomdibaniso wokugqibela.

Uhlobo lweentonga zokubhengeza

Uhlobo lwezibonda ezisetyenzisiweyo zixhomekeke kwisicelo esithile kunye nezinto ezidityanisiweyo. Ezinye iintlobo eziqhelekileyo zeentonga zokubrawuza ziquka:

1 

2. Ii-Bronze Brazing Rods: I-Bronze rods zenziwe nge-alloys ye-copper-tin kwaye zidla ngokusetyenziselwa ukudibanisa intsimbi, intsimbi ekhandiweyo, kunye nezinye iintsimbi ezine-ferrous.

3. Iintsimbi zeSilver Brazing: Iirodi zeSilver zinepesenti ephezulu yesilivere kwaye zisetyenziselwa ukudibanisa uluhlu olubanzi lwesinyithi, kuquka ubhedu, ubhedu, intsimbi engatyiwa, kunye ne-nickel alloys. Banikezela ngamajoyina anamandla kwaye athembekileyo.

4 Ngokuqhelekileyo ziqulethe i-silicon njengeyona nto iphambili yokudibanisa.

5. I-Flux-coated Brazing Rods: Ezinye izibonda ze-brazing ziza kunye ne-flux coating, enceda ukususa i-oxides kunye nokuphucula ukuhamba kwentsimbi yokuzalisa ngexesha lokuqhaqha. Iinduku ezigqunywe nge-Flux ziqhele ukusetyenziselwa ukunyibilikisa ubhedu, ubhedu kunye nezixhobo zobhedu.

Twasebenzisa iintonga zokutshisaPDCumsiki welding

I-PDC cutters ibrazed kwintsimbi okanye umzimba we-matrix we-PDC drill bit. Ngokwendlela yokufudumala, indlela yokutshisa iyakwazi ukwahlula kwi-flame brazing, i-vacuum brazing, i-vacuum diffusion bonding, i-high-frequency induction brazing, i-laser beam welding, njl.

Xa i-brazing cutters ye-PDC, kubalulekile ukusebenzisa intonga yokuqhafaza enendawo yokuncibilika ephantsi kune-PDC cutter material ukukhusela umonakalo kwi-cutter. Inkqubo yokuqhafaza ibandakanya ukufudumeza intonga ye-brazing kunye ne-PDC cutter assembly kwiqondo lokushisa elithile, ukuvumela i-alloy brazing inyibilike kwaye ihambe phakathi kwe-cutter kunye ne-substrate, idala ibhondi eqinile.Ngokubanzi, iialloyi zesilivere zebrazing ziqhele ukusetyenziselwa ukuwelda iPDC cutter, idla ngokuyilwa ngesilivere, ikopolo, kunye nezinye izinto ukuphumeza iimpawu ezinqwenelekayo. Ezi ngxubevange zinesiqulatho esiphezulu sesilivere, indawo yokunyibilika esezantsi kunye neempawu ezintle zokumanzisa. Isiqulatho esisisilivere esiphezulu siqinisekisa ukumanzisa okulungileyo kunye nokudibana phakathi kwe-PDC cutter kunye ne-drill bit body material.

Kukho iintonga zesilivere kunye nepleyiti yokuqhola isilivere, enokusetyenziselwa ukuwelda ii-PDC cutters. Ngokusisiseko, iintonga zesilivere ezine-45% ukuya kwi-50% yesilivere ifanelekile kwi-PDC cutter welding. Umgangatho onconywayo wentonga zesilivere kunye nepleyiti yiBag612 grade, ene-50% yesiqulatho sesilivere.

Ubushushu bokutshisa xa welding PDC cutters.

Ubushushu bokusilela kwe-polycrystalline diamond layer bujikeleze i-700 ° C, ngoko ke ubushushu bomgangatho wedayimani kufuneka ilawulwe ngaphantsi kwe-700 ° C ngexesha lenkqubo ye-welding, ihlala i-630 ~ 650 ℃。

Lilonke, iinduku zokubrawuza zidlala indima ebalulekileyo kwi-PDC cutter welding, ukuqinisekisa iqhina eliqinileyo nelithembekileyo phakathi komsiki wePDC kunyedrill bit body, okuyimfuneko ekusebenzeni kunye nokuqina kwezixhobo zokugaya kwishishini leoli kunye negesi.

Ukuba ufuna i-PDC cutter, i-brazing rods yesilivere, okanye iingcebiso ezingaphezulu ze-welding. Wamkelekile ukuba uqhagamshelane nathi nge-imeyileIrene@zzbetter.com.
