PDC Drill Bit Welding Reference

PDC kubowola pang'ono kuyenera kukhalabe kuuma kwakukulu, kulimba kwambiri, kukana kugwedezeka kwamafuta, komanso kukana kwa dzimbiri. Njira yoyamba yowotchera moto imaphatikizapo chithandizo chowotcherera chisanadze, kutentha, kuteteza kutentha, kuziziritsa, ndi chithandizo cha pambuyo pa kuwotcherera.

Gwirani ntchito musanayambe kuwotcherera kwa PDC

1: sandblast ndikuyeretsa chodula cha PDC

2: sandblast ndi kuyeretsa thupi la kubowola (pukuteni ndi mowa thonje mpira)

3: Konzani solder ndi flux (nthawi zambiri timagwiritsa ntchito 40% siliva solder)

Chidziwitso: chodulira cha PDC ndi kubowola sikuyenera kuipitsidwa ndi mafuta

Kuwotcherera kwa PDC cutter

1: Ikani flux pamalo pomwe chodulira cha PDC chimafunikira kuwotcherera pathupi pang'ono

2: Ikani thupi pang'ono mu ng'anjo yapakati yapakati kuti itenthetse

3: Mutatha kutentha, gwiritsani ntchito mfuti yamoto kutentha thupi

4: Sungunulani solder mu PDC recess ndi kutentha mpaka solder asungunuke

5: Ikani PDC mu dzenje la concave, pitirizani kutentha thupi la kubowola mpaka solder itasungunuka ndi kutuluka ndikusefukira, ndikuthamanga pang'onopang'ono ndikuzungulira PDC panthawi ya soldering. (Cholinga chake ndikutulutsa mpweya ndikupangitsa kuti kuwotcherera kukhale kofanana)

6: Musagwiritse ntchito mfuti yamoto kutentha chodulira cha PDC panthawi yowotcherera, kutentha thupi pang'ono kapena kuzungulira PDC, ndikulola kutentha pang'onopang'ono kupita ku PDC. (Chepetsani kuwonongeka kwa kutentha kwa PDC)

7. Kutentha kwa kuwotcherera kuyenera kuyendetsedwa pansi pa 700 ° C panthawi yowotcherera. Nthawi zambiri ndi 600 ~ 650 ℃.

Pambuyo kubowola pang'ono ndi welded

1: Pambuyo pobowola ndi welded ikani PDC kubowola pang'ono mu malo kusunga kutentha mu nthawi, ndi kutentha kwa kubowola ndi utakhazikika pang'onopang'ono.

2: Muziziziritsa pobowola mpaka 50-60 °, chotsani chobowola, sandblast ndikupukuta. fufuzani mosamala ngati PDC kuwotcherera malo ndi welded mwamphamvu ndi ngati PDC ndi welded kuonongeka.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
