3  Ihe Ị Kwesịrị Ịma Banyere PDC Brazing

A na-akụ ndị na-egbutu PDC na nchara ma ọ bụ matriks ahụ nke ihe mkpọpu PDC. Dị ka usoro kpo oku si dị, usoro brazing nwere ike kewaa n'ime ọkụ brazing, vacuum brazing, vacuum diffusion bonding, elu-frequency induction brazing, laser beam welding, wdg. Ọkụ ọkụ ọkụ dị mfe iji rụọ ọrụ ma jiri ya mee ihe. Taa, anyị ga-achọ ịkọrọ ntakịrị gbasara PDC ire ọkụ.

Gịnị bụ ire ọkụ brazing?

Ịgba ọkụ n'ọkụ bụ usoro ịgbado ọkụ nke na-eji ire ọkụ sitere n'ọkụ gas na-emepụta maka ikpo ọkụ. Isi usoro nke ire ọkụ brazing gụnyere ọgwụgwọ tupu weld, kpo oku, nchekwa ọkụ, oyi, ọgwụgwọ weld, wdg.

Gịnị bụ usoro nke PDC ire ọkụ brazing?

1. Tupu weld ọgwụgwọ

(1) sandblast ma hichaa onye na-egbutu PDC na ahụ PDC drill bit ahụ. E kwesịghị iji mmanụ metọọ ihe na-egbutu PDC na ihe ọkụkụ.

(2) kwadebe ihe na-ere ahịa na flux. Anyị na-ejikarị 40% ~ 45% ọlaọcha na-ere ahịa maka PDC brazing. A na-eji mgbanwe ahụ egbochi oxidation n'oge brazing.

2. Nchekwa ọkụ na okpomọkụ

(1) Kpoo anụ ahụ PDC kpokuo ọkụ n'ime ọkụ etiti oge ruo ihe dịka 530 ℃.

(2) Mgbe preheating, na-eji ire ọkụ egbe ikpo bit ahu na PDC cutter. Anyị ga-achọ egbe ire ọkụ abụọ, otu maka ikpo ọkụ nke ọkpọ ahụ na otu maka ikpo ọkụ nke onye na-egbutu PDC.

(3) Gbanyụọ ihe na-ere ahịa na ezumike PDC wee kpoo ya ruo mgbe ihe na-agbaze agbaze. Tinye PDC n'ime oghere concave, na-aga n'ihu na-ekpo ọkụ ahụ ruo mgbe ihe na-ere ya gbazere ma na-asọpụta ma na-ejubiga ókè, ma jiri nwayọọ nwayọọ na-agbagharị ma gbanwee PDC n'oge usoro ire ere. Tinye mmiri n'ebe ọ dị mkpa ka a kpachie onye na-egbutu PDC iji gbochie oxidation.

3. ọgwụgwọ oyi na post-weld

(1). Mgbe a kpasuru ndị na-egbutu PDC, tinye olulu PDC n'ime ebe nchekwa okpomọkụ n'oge, ma jiri nwayọọ nwayọọ mee ka okpomọkụ dị jụụ.

(2) Mgbe emechara ihe nkedo ahụ dị na 50-60 °, anyị nwere ike wepụ ihe ọkụkụ ahụ, sandblast ma kpochaa ya. Jiri nlezianya lelee ma ebe ịgbado ọkụ PDC agbadoro nke ọma yana ma agbado PDC mebiri emebi.

Gịnị bụ okpomoku brazing?

The ọdịda okpomọkụ nke polycrystalline diamond oyi akwa bụ gburugburu 700C, otú okpomọkụ nke diamond oyi akwa ga-achịkwa n'okpuru 700 Celsius C n'oge ịgbado ọkụ usoro, na-emekarị 630 ~ 650 ℃.

Ọ bụrụ na ị nwere mmasị na tungsten carbide rods ma chọọ ozi ndị ọzọ na nkọwa, ị nwere ike ịkpọtụrụ anyị site na ekwentị ma ọ bụ mail n'aka ekpe, ma ọ bụ zipu US MAIL na ala nke ibe.
