Ndodo za brazing zomwe zimagwiritsidwa ntchito powotcherera PDC cutter

Kodi zokopa zokopa ndi chiyani

Brazing rod ndi zitsulo zodzaza zomwe zimagwiritsidwa ntchito popanga chitsulo, yomwe ndi njira yolumikizirana yomwe imagwiritsa ntchito kutentha ndi zomangira kuti zimangire zitsulo ziwiri kapena kupitilirapo., monga chitsulo ku chitsulo kapena mkuwa mpaka mkuwa. Ndodo zachitsulo nthawi zambiri zimapangidwa ndi alloy yachitsulo yomwe imakhala ndi malo otsika osungunuka kuposa zitsulo zomwe zimagwirizanitsidwa. Mitundu yodziwika bwino ya ndodo zowotcha imaphatikizapo mkuwa, bronze, siliva, ndi ma aluminiyamu aloyi. Mtundu weniweni wa ndodo yachitsulo yomwe imagwiritsidwa ntchito zimadalira zipangizo zomwe zimagwirizanitsidwa ndi zomwe zimafunidwa za mgwirizano womaliza.

Mtundu wa ndodo za brazing

Mtundu wa ndodo zomangira zomwe zimagwiritsidwa ntchito zimadalira momwe akugwiritsira ntchito komanso zipangizo zomwe zikuphatikizidwa. Mitundu ina yodziwika bwino ya brazing ndodo ndi:

1. Nkhombo za Brass Brazing: Ndodozi zimapangidwa ndi aloyi ya mkuwa-zinc ndipo nthawi zambiri zimagwiritsidwa ntchito polumikiza zinthu za mkuwa, zamkuwa, ndi zamkuwa.

2. Nkhombo za Bronze: Ndodo za mkuwa zimapangidwa ndi aloyi a mkuwa ndipo nthawi zambiri amagwiritsidwa ntchito polumikiza zitsulo, chitsulo chonyezimira, ndi zitsulo zina.

3. Silver Brazing Rods: Zombo za Silver zimakhala ndi siliva wochuluka kwambiri ndipo zimagwiritsidwa ntchito polumikiza zitsulo zosiyanasiyana, kuphatikizapo mkuwa, mkuwa, zitsulo zosapanga dzimbiri, ndi ma aloyi a faifi tambala. Amapereka mgwirizano wamphamvu komanso wodalirika.

4. Nkhombo za Aluminium: Ndodozi zimapangidwira kuti zilumikizidwe ndi ma aluminiyamu ndi ma aloyi. Nthawi zambiri amakhala ndi silicon monga gawo lalikulu la alloying.

5. Flux-coated Brazing Rods: Ndodo zina za brazing zimabwera ndi zokutira zotulutsa, zomwe zimathandiza kuchotsa ma oxides ndikuwongolera kuyenda kwa chitsulo chodzaza panthawi yowotcha. Ndodo zokutidwa ndi Flux zimagwiritsidwa ntchito kwambiri poyezera zinthu zamkuwa, zamkuwa, ndi zamkuwa.

Tzida zankhondo zomwe zimagwiritsidwa ntchitoPDCwodula kuwotcherera

Odula a PDC amawongoleredwa ku chitsulo kapena thupi la matrix la PDC drill bit. Malinga ndi njira yowotchera, njira yowotchera imatha kugawidwa kukhala moto woyaka moto, kutsekemera kwa vacuum, kulumikiza kwa vacuum diffusion, kuthamanga kwapamwamba kwambiri, kuwotcherera kwa laser, ndi zina.

Pamene brazing PDC cutters, ndikofunika kugwiritsa ntchito ndodo yachitsulo yokhala ndi malo osungunuka otsika kuposa PDC cutter material kuti ateteze kuwonongeka kwa wodulayo. Kuwotcha kumaphatikizapo kutenthetsa ndodo yachitsulo ndi msonkhano wa PDC wodula kutentha kwapadera, kulola kuti alloy brazing asungunuke ndikuyenda pakati pa wodula ndi gawo lapansi, kupanga mgwirizano wolimba.Nthawi zambiri, ma aloyi a silver brazing amagwiritsidwa ntchito powotcherera PDC cutter, nthawi zambiri amakhala ndi siliva, mkuwa, ndi zinthu zina kuti akwaniritse zomwe mukufuna. Ma aloyiwa ali ndi siliva wambiri, sasungunuka kwambiri komanso amanyowetsa bwino. Zomwe zili siliva wokwera zimatsimikizira kunyowetsa bwino komanso kulumikizana pakati pa PDC cutter ndi drill bit body material.

Pali ndodo zasiliva zopangira siliva ndi mbale yasiliva, yomwe imatha kugwiritsidwa ntchito kuwotcherera ocheka a PDC. Kwenikweni ndodo zopangira siliva zokhala ndi siliva 45% mpaka 50% ndizoyenera kuwotcherera PDC cutter. Zovomerezeka giredi ya silver brazing rods ndi mbale ndi giredi ya Bag612, yomwe ili ndi 50% ya siliva.

Kutentha kwamphamvu powotchera odula a PDC.

Kulephera kutentha kwa polycrystalline diamondi wosanjikiza ndi kuzungulira 700 ° C, kotero kutentha kwa diamondi wosanjikiza ayenera kulamulidwa m'munsimu 700 ° C pa ndondomeko kuwotcherera, kawirikawiri 630 ~ 650 ℃。

Ponseponse, ndodo zomangira zimagwira ntchito yofunika kwambiri pakuwotcherera kwa PDC cutter, kuonetsetsa kuti pali mgwirizano wamphamvu komanso wodalirika pakati pa chodula cha PDC ndikubowola pang'ono thupi, zomwe ndizofunikira pakugwira ntchito komanso kulimba kwa zida zobowola mumakampani amafuta ndi gasi.

Ngati mukufuna chodulira cha PDC, ndodo zasiliva zowotcherera, kapena nsonga zowotcherera. Takulandilani kuti mutitumizire imeloIrene@zzbetter.com.

Pezani ZZBETTER kuti mupeze njira yosavuta komanso yachangu ya odula a PDC!
