Kaʻina wili o Extrusion Tap Thread

Me ka hoʻohana ākea o nā metala non-ferrous, nā ʻāpana a me nā mea ʻē aʻe me ka plasticity maikaʻi a me ka paʻakikī, paʻakikī ke hoʻokō i nā koi kikoʻī no ka hoʻoili ʻana i nā kaula i loko o kēia mau mea me nā paʻi maʻamau.
Ua hōʻoia ka hoʻomaʻamaʻa hana lōʻihi i ka hoʻololi wale ʻana i ke ʻano o ka ʻoki ʻoki (e like me ka ʻimi ʻana i ka geometry maikaʻi loa) a i ʻole ka hoʻohana ʻana i kahi ʻano mea paʻi hou ʻaʻole hiki ke hoʻokō piha i nā koi o ke kūlana kiʻekiʻe, kiʻekiʻe-huahana a haʻahaʻa. kumu kūʻai machining screw hole.

ʻO ka "Cold extrusion chipless processing" he ʻano hana hou o loko, ʻo ia hoʻi, ma ka lua lalo o ka mea hana i hana mua ʻia, hoʻohana ʻia ka ʻōpala chipless (extrusion tap) e hoʻokuʻu i ke anuanu i ka mea hana e hana i ka deformation plastic e hana i kahi kaula kūloko. .
No ka mea, hiki i ka hana chipless o ka extrusion anuanu ke hoʻopau i ka hana ʻana i loko o ka pae i hiki ʻole ke hana ʻia e ka ʻoki ʻoki maʻamau, no laila ke ulu nui nei ka hoʻohana ʻana o kēia kaʻina hana, a ʻoi aku ka waiwai o ka hana ʻana o ka extrusion taps. .

ʻO ka conical extrusion cone ka mea maʻamau i hoʻohana ʻia i ka chipless tap extrusion cone, nona nā mea maikaʻi o ka extrusion māmā, torque liʻiliʻi, a me ka roughness maikaʻi o ke kaula i hana ʻia.No ka mea, ʻoi aku ka paʻakikī o ka wili ʻana o kēia cone extruded ma mua o ka cone extruded cylindrical: i ka wā e wili ai, ʻike ʻia ke kihi cone extruded a o kona anawaena waena e ka taper, a me ka papa make. ʻO ka papa hana e hoʻoneʻe a hoʻokele i ke kiʻi huila wili e neʻe radially e hoʻopau i ka wili ʻana o ka pila chipless i loko o ka kihi taper.

Hoʻokomo ʻia ka paʻi kūloko me ke kaula hoʻi hope – kūʻai i ka pā me ka lola ʻāwili, ka milo hana ʻana i ka uʻi kīwila, ke kaomi ʻana i ka milo e hoʻokomo i ka huahana kūloko ma Alibaba.com
