Mumapurojekiti ekuchera pasi-pasi-gomba, kuitira kuti uwane chinangwa chekushanda uye nekukurumidza kuchera, zvakakosha kuti usarudze mabheti ekuchera-yepamusoro-soro uye anobudirira, ndiko kuti, kusarudza pasi-iyo. -hole drill bits ane zvimiro zvakasiyana maererano nenzira dzakasiyana dzekuchera uye mhando dzedombo. Zvinhu zvakatevedzana senge chibooreso chekuguma kwechiso chimiro, chimiro chepoda discharge groove, carbide zino chimiro uye saizi, kuoma kwechibooreso chemuviri, nezvimwe zvinokanganisa zvakananga kudhirowa kwedombo, kudhirowa kwemhando, kutwasanuka kweblasthole. , drill bit life uye kushanda zvakanaka. Naizvozvo, kusarudza dhiri rakakodzera rakakosha mumapurojekiti ekuchera dombo.
Nekuda kwepamusoro-kudzvanya pasi-iyo-gomba mabheti (zviboorero) zvine chekuita, kune mana makuru ekupedzisira ekugadzira kumeso mafomu ari kushandiswa pari zvino, anoti: end face convex type, end face flatness, end face concave type uye kuguma kumeso kwakadzika. concave centre type. Carbide inonyanya kushandisa mazino ebhora, mazino echitubu kana mazino ebhora uye mazino echitubu pakugadzirisa mazino.
1. Convex end face type: The convex end face type high-pressure down-the-hole drill bit (drill bit) inogona kuchengetedza dombo rakakwirira pakuchera matombo aripakati-akaoma uye akaomarara anokwenya, asi kutara kwacho hakuna kunaka, uye haina kukodzera mapurojekiti ekuchera matombo ane zvinodiwa zvakakwirira zve blasthole kutwasanuka.
2. Flat end face type: The flat end face type high-pressure down-the-hole drill bit (drill bit) yakasimba uye yakasimba, uye inokodzera kuchera matombo akaoma uye akaoma zvakanyanya. Inokodzerawo kuchera dombo repakati-rakaoma uye dombo rakapfava rine zvakaderera zvinodiwa zve blasthole kutwasanuka.
. process, inochengetedza dhiri bhidhi's centering performance, uye blasthole yakacherwa ine kunaka kutwasanuka. Pamusoro pezvo, iyi drill bit ine irinani yekubvisa guruva mhedzisiro uye nekukurumidza kuchera kumhanya. Iyo yakanyanya-kumanikidza pasi-iyo-gomba drill bit iyo ikozvino inoshandiswa zvakanyanya pamusika.
4. Kupedzisa chiso chakadzika concave centre mhando: Iyo yekupedzisira yakatarisana yakadzika concave centre mhando yakakwira mhepo yekutsikirira pasi-the-gomba drill bit (drill bit) ine yakadzika concave centre chikamu chiri pakati pekupedzisira kumeso, iyo inoshandiswa nucleation mu. nzira yekuchera dombo. Kuchera makomba akadzika kunogona kuchengetedza kutwasuka kwe blasthole, asi simba rayo rekuguma kwechiso harina simba kupfuura mamwe marudzi ekuchera mabheti, saka rinongokodzera kuchera dombo rakapfava uye dombo repakati-rakaoma.
