Kukuya Maitiro eExtrusion Tap Thread

Nekushandiswa kwakakura kwesimbi dzisina-ferrous, alloys uye zvimwe zvinhu zvine purasitiki yakanaka uye kuomarara, zvakaoma kuzadzisa izvo zvinodikanwa zvemukati tambo yekugadzirisa zvinhu izvi nemapombi akajairwa.
Yenguva refu yekugadzirisa maitiro yakaratidza kuti kungoshandura chimiro chepombi yekucheka (yakadai sekutsvaga yakanakisa geometry) kana kushandisa rudzi rutsva rwepombi zvinhu hazvichakwanise kuzadzisa zvizere zvinodiwa zvemhando yepamusoro, yepamusoro-chigadzirwa uye inodhura machining screw holes.

"Cold extrusion chipless processing" inzira itsva yemukati yekugadzira tambo, ndiko kuti, pagomba rezasi rebasa rakagadzirirwa, iyo chipless tap (extrusion tap) inoshandiswa kutonhora-extrude workpiece kuti ibudise deformation yepurasitiki kuti iite tambo yemukati.
Nekuti iyo chipless processing yechando extrusion inogona kupedzisa iyo yemukati tambo yekugadzirisa iyo isingagone kuitwa neyakajairika tepi yekucheka, saka mashandisirwo eiyi maitiro ari kuramba achiwedzera, uye kugaya kwematepi eextrusion kunowedzerawo kukoshesa vanhu.

Iyo conical extrusion cone ndiyo inonyanya kushandiswa chipless tap extrusion koni, ine zvakanakira mwenje extrusion, diki torque, uye yakanaka roughness yeshinda yakagadziriswa. Nekuti dhayamita yaro yekunze nedhayamita yepakati zvese zvine matepi, kukuya kwekoni iyi yakawedzera kunetsa kupfuura iyo yecylindrical extruded cone: panguva yekukuya, iyo extruded cone angle a yepakati dhayamita yepakati inoonekwa ne taper, uye ndiro inofa ndiyo Inoshanda uye inodhiraivha vhiri furemu kuti ifambe mbichana mbichana mbichana mbichana.
