Maitiro Ekukuya eExtrusion Tap Thread

Nekushandiswa kwakakura kwesimbi dzisina ferrous, alloys nezvimwe zvinhu zvine plasticity yakanaka uye kusimba, zvakaoma kusangana nezvinodiwa nemazvo zvekugadzirisa shinda dzemukati mezvinhu izvi nemapombi akajairwa.
Maitiro ekugadzirisa kwenguva refu akaratidza kuti kungochinja chimiro chepombi yekucheka chete (sekutsvaga chimiro chakanakisa) kana kushandisa mhando itsva yezvinhu zvepombi hakuchakwanisi kuzadzisa zvizere zvinodiwa zvemaburi emasikuru emhando yepamusoro, ekugadzira zvakanyanya uye asingadhuri.

"Kugadzira michina isina chip isina kutonhora" inzira itsva yekugadzirisa michina yemukati, kureva kuti, paburi repasi rechinhu chakagadzirwa kare, pombi isina chip (pombi yekuwedzera) inoshandiswa kuburitsa michina yemukati nechando kuti igadzire purasitiki kuti igadzire shinda yemukati.
Nekuti kugadzirisa pasina chips ye extrusion inotonhora kunogona kupedzisa kugadzirisa kwemukati kweshinda uko kusingagone kuitwa nekucheka kwepombi kwakajairika, saka kushandiswa kwemaitiro aya kuri kuwedzera, uye kugadzirisa kukuya kwemapombi e extrusion kuri kukosheswawo nevanhu.

Koni yekuwedzera ine conical ndiyo inonyanya kushandiswa chipless tap extrusion cone, ine mabhenefiti ekuwedzera kwakareruka, torque diki, uye roughness yakanaka yeshinda yakagadziriswa. Nekuti dhayamita yayo yekunze nedhayamita yepakati zvese zvine tapers, kukuya kwekoni iyi yakaburitswa kwakaoma kupfuura kwekoni yakaburitswa ine cylindrical: panguva yekukuya, kona yekoni yakaburitswa ine a yedhayamita yayo yepakati inoonekwa netaper, uye die plate ndiyo inofamba uye inotyaira grinding wheel frame kuti ifambe radially kuti ipedze kukuya kwetap isina chipless mukona yetaper.
