Ibintu 3 Ugomba kumenya kuri PDC Brazing

Imashini za PDC zometse kumyuma cyangwa matrix yumubiri wa PDC bito. Ukurikije uburyo bwo gushyushya, uburyo bwo gushakisha burashobora kugabanywamo gucana flame, brazing vacuum, guhuza vacuum diffuzion, gushakisha inshuro nyinshi induction brazing, gusudira laser beam, nibindi. Gukoresha Flame biroroshye gukora kandi bikoreshwa cyane. Uyu munsi twifuje gusangira bike kubijyanye na PDC flame brazing.

Umuriro ugurumana ni iki?

Flame brazing nuburyo bwo gusudira bukoresha urumuri ruterwa no gutwika gaze kugirango ushushe. Inzira nyamukuru yo gutwika flame ikubiyemo kuvura mbere yo gusudira, gushyushya, kubika ubushyuhe, gukonjesha, kuvura nyuma yo gusudira, nibindi.

Ni ubuhe buryo bwo gucana umuriro wa PDC？

1. Kuvura mbere yo gusudira

. PDC ikata na drill bit ntigomba gusiga amavuta.

(2) gutegura kugurisha na flux. Mubisanzwe dukoresha 40% ~ 45% kugurisha ifeza mugukoresha PDC. Flux ikoreshwa mukurinda okiside mugihe cyo gushakisha.

2. Gushyushya no kubika ubushyuhe

(1) Shyushya PDC drill bit umubiri mumatara aringaniye kugeza kuri 530 ℃.

(2) Nyuma yo gushyushya, koresha imbunda ya flame kugirango ushushe umubiri wa bito na PDC. Tuzakenera imbunda ebyiri za flame, imwe yo gushyushya umubiri wa biti imwe nindi yo gushyushya icyuma cya PDC.

. Shira PDC mu mwobo ucuramye, komeza ushyushya umubiri wa drill bit kugeza igihe uwagurishije ashonga kandi atemba kandi yuzuye, hanyuma wiruke buhoro kandi uzunguruka PDC mugihe cyo kugurisha. Koresha flux ahantu hagomba gukata PDC kugirango ikingire okiside.

3. Gukonjesha no kuvura nyuma yo gusudira

(1). Nyuma yo gukata PDC imaze gushyirwaho, shyira bito ya PDC ahantu ho kubika ubushyuhe mugihe, hanyuma ukonje buhoro buhoro ubushyuhe bwa bito.

. Witonze urebe niba aho PDC yo gusudira isudira neza kandi niba PDC isudira yangiritse.

Ubushyuhe bukabije ni ubuhe?

Ubushyuhe bwo kunanirwa bwa polycrystalline ya diyama igera kuri 700 ° C, bityo ubushyuhe bwurwego rwa diyama bugomba kugenzurwa munsi ya 700 ° C mugihe cyo gusudira, mubisanzwe 630 ~ 650 ℃.

Niba ushishikajwe na tungsten carbide inkoni kandi ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa ubutumwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
