Nā ʻōlelo aʻoaʻo a ka poʻe loea Bolt Thread, heluhelu i kēia ʻatikala.

Hoʻokaʻawale nui ʻia ka pae i ka pae pili a me ka pae hoʻokele.

No ka hoʻopili ʻana i nā pae, ʻo nā hana hana nui ke kīkiʻi ʻana, ka ulana ʻana, ka huli ʻana, ka ʻolokaa ʻana, ka ʻānai ʻana, a pēlā aku. No ka pae hoʻoili, hana maʻalahi nā ʻano hana a me ka hoʻohuli maikaʻi - wili ʻana, wili ʻana o ka puahiohio - huli ʻino a maikaʻi hoʻi, etc.

Eia nā ʻano hana like ʻole.

1. ʻOki ana i ka pae

ʻO ka maʻamau, pili ia i ke ʻano o ka mīkini hana ma kahi mea hana me kahi mea ʻoki a i ʻole mea hana abrasive, ʻo ia hoʻi me ka hoʻohuli ʻana, ka wili ʻana, ka pēni ʻana, ka wili ʻana, ka wili ʻana, a me ka ʻoki ʻana i ka puahiohio, a pēlā aku. o ka mīkini pono hana e hōʻoia i ka mea huli, mīkini mea wili, a i ʻole ka wili wili hiki ke neʻe pololei i hoʻokahi alakaʻi a kaulike hoʻi ma ke kuhikuhi axial o ka hana. Ma ke kuʻi ʻana a i ʻole ke wili ʻana, huli ka mea hana (piula wai a make paha) e pili ana i ka mea hana, a neʻe axally i ka mea hana (a i ʻole ka workpiece) e ke alaloa wili i hana mua ʻia.

Hiki ke hana i ka pae i kahi lathe me ka huli ʻana i kahi mea hana a i ʻole mea hana kuʻina pae. ʻO ka huli ʻana i ke pae me kahi mea hana huli ʻano he ʻano maʻamau no ka ʻāpana hoʻokahi a me ka hana liʻiliʻi o kāna pūʻulu ma muli o kāna ʻano maʻalahi; ʻo ka huli ʻana me ka mea ʻokiʻoki he mea pono hana kiʻekiʻe, akā paʻakikī ka ʻōnaehana o nā mea hana, no laila kūpono wale ia no ka hana waena a me ka nui o ka hana o ka wili liʻiliʻi me ka wili liʻiliʻi. Ma ka laulā, ʻo ka pitch pitch o ka huli ʻana i ka pae trapezoidal e ka lathe maʻamau hiki wale i 8-9 papa (JB2886-81, ka mea like ma lalo); hiki ke hoʻomaikaʻi maikaʻi ʻia ka huahana a pololei paha i ka wā e ulana ai ka mīkini hana ma ka lathe pae hana kūikawā.

2. Mīkini wili

Lawe ʻia ka wili palaoa ma kahi mīkini wili palaoa me kahi ʻoki diski a i ʻole kahi mea ʻoki hui. Hoʻohana nui ʻia ka mea mīkini wili palaoa no ka wili ʻana i nā pae o waho trapezoidal ma ka koʻokoʻo, ka ilo, a me nā mea hana ʻē aʻe. Hoʻohana ʻia ka mea ʻoki mīkini wili palaoa e wili i nā pae maʻamau a kūwaho hoʻi a me nā pae lepe. No ka mea wili ʻia ia e ka mea ʻoki wili nunui a ʻoi aku ka lōʻihi o kāna ʻāpana hana ma mua o ka lōʻihi o ka pae e hoʻoponopono ʻia ai, hiki ke hana ʻia ka mea hana e 1.25 ~ 1.5 rotation wale nō, a kiʻekiʻe loa ka hana. Hiki i ka pitch pitch o ka wili palaoa ke piʻi i ka papa 8-9, a ʻo ka ʻāpana o R 5-0.63 μm. Kūpono kēia hana no ka hana nuipaʻa o nā mea hana o ka pae me ka maʻamau maʻamau a i ʻole ka mīkini maʻamau ma mua o ka wili.

3. wili wili

Hoʻohana nui ʻia ia no ka mīkini pono ʻana i ka pae o ka mea hana paʻa i ka wili wili. Wahi a nā ʻano ʻāpana ʻāpana o ka wili wili, hiki ke hoʻokaʻawale ʻia i hoʻokahi wili wili laina a me kahi wili wili laina he nui. Hōʻike nā hopena i ka pololei o ka pitch o ka wili wili laina hoʻokahi he 5-6 ka nui, a ʻo R 1.25-0.08 μm ka maʻalahi o ka ʻili, he maʻalahi ia no ke kāhiko ʻana i nā lole huila. Kūpono kēia ala no ka wili ʻana i ke kīkī kēpau, ka ana o nā pae, nā ilo, kahi pūʻulu liʻiliʻi o ka mea hana i wili ʻia, a me ka wili ʻana i ka wili. Māhele ʻia ka wili wili nunui laina i ʻano hana wili lōʻihi a ʻoki ʻia i ke ʻano wili. ʻO ka laulā o ka wili wili i ke ʻano wili lōʻihi e ʻoi aku ka liʻiliʻi ma mua o ka lōʻihi o ka pae e lepo ai, a hiki i ka pae ke kuʻi ʻia i ka nui hope loa i ka neʻe ʻana o ka huila i ka manawa hoʻokahi a i kekahi mau manawa. ʻO ka laulā o ka wili wili o keʻoki i ke ʻano wili ʻoi aku ka nui ma mua o ka lōʻihi o ka pae i lepo. ʻO ka wili wili ʻokiʻoki i ka papa o ka mea hana radally, hiki ke hoʻopau ʻia ka mea hana ma hope o nā 1.25 revolutions. ʻOi aku ka kiʻekiʻe o ka huahana, akā ʻoi aku ka haʻahaʻa o ke kikoʻī, a ʻoi aku ka paʻakikī o ke kāhiko ʻana i ka huila wili. ʻO kaʻokiʻoki i ke ʻano wili kūpono no ka hoʻoluʻu ʻana i nā piʻo wili me ka nui a me ka wili ʻana i nā pae hoʻopaʻa.
4. wili wili

ʻO ke ʻano nut a i ʻole ka ʻāʻī type thread lapping tool i hana ʻia i nā mea palupalu e like me ka hao hao e hoʻohana ʻia e wili i nā ʻāpana o ka pae mīkini me ka hewa pitch i mua a hoʻohuli i ka hoʻololi e hoʻomaikaʻi i ka pololei o ka pitch. Hoʻopau pinepine ʻia ka deformation o ka pae o ka pae i paʻakikī e ka wili e hoʻomaikaʻi ai i ka pololei.
5. Kaomi a me ka jacking

ʻO ke kāomi ʻana e hoʻohana i kahi nui o ka wili e wili ai i ka piula i loko o ka lua o ka hana i hana ʻia e hana i nā pae i loko. E hoʻohana ka lima i ka make e ʻokiʻoki i nā pae i waho o ka koʻokoʻo (a i ʻole paipu) workpiece. ʻO ka mīkini pono o ke kāomi ʻana a i ʻole ka lima lima e pili ana i ka kikoʻī o ka piula wai a make paha. ʻOiai he nui nā ala e hoʻoponopono ai i nā pae i loko a me waho, ʻo nā pae o loko o ke anawaena liʻiliʻi hiki ke hilinaʻi i ka hana ʻana o ka piula wai. Hiki ke hana ʻia ke kāomi ʻana a me ka wili lima, e like me ka lathes, nā mīkini drill, kaomi ʻana, a me nā mīkini wili.

Koina koho o ka ʻoki ʻana i nā palena no ka lathe pae

Ma muli o ke kaha kiʻi ʻana e wehewehe ai i ka pitch (a i ʻole kēpau) o ka pae, ʻo ke kī e koho ai i nā ʻokiʻoki e hoʻoholo ai i ka wikiwiki o ka wili “n” a me ka ʻoki hohonu “ap”.

1) Koho o ka wikiwiki kālī

Wahi a ke ʻano o ka huli o ka kālī, hoʻokahi huli a me ka mea hana hānai i hoʻokahi kēpau ke huli i ka pae, hoʻoholo ka wikiwiki kālī i koho ʻia i ka wikiwiki o ka hānai o ka lathe CNC. Ke alakaʻi kēpau (pitch in case of the single thread) in the thread processing program section is same to the feed speed "vf" express by feed rate "f (mm / r)".
vf = nf (1)

Hiki ke ʻike ʻia mai ke kumumanaʻo i ka wikiwiki o ka hānai “vf” kūlike kūpono i ka helu hānai “f”. Inā koho ʻia ka wikiwiki o ka mīkini mīkini i kiʻekiʻe loa, pono ke kiʻekiʻe o ka wikiwiki hānai i hoʻohuli ʻia ma mua o ka wikiwiki hānai i helu ʻia o ka mīkini mīkini. No laila, pono e noʻonoʻo ʻia ka hoʻonohonoho ʻōnaehana o ka ʻōnaehana hānai a me ka hoʻonohonoho uila o ka mīkini pono i ke koho ʻana i ka wikiwiki o ka spindle ke huli nei i ka pae, i mea e pale ʻole ai i ka hanana o "thread disordered" a i ʻole ka pitch kokoke i ka hoʻomaka / hopena i kū ʻole. nā koina.

Ma waho aʻe, pono e hoʻomaopopo ʻia i ka manawa e hoʻomaka ai ke kaʻina o ka pae, ʻaʻole hiki ke hoʻololi i ka nui o ka wikiwiki i ka spindle, a me ka wikiwiki e hoʻohana i ka mīkini hoʻopau e hoʻohana i ka waiwai i koho ʻia i ka manawa o ka hānai mua. Ināʻole, e hoʻokumu ka ʻōnaehana CNC i ka "thread disordered" ma muli o ka "overshoot" o ka hōʻailona pulse kuhikuhi o ka encode pulse.

2) Koho o ka hohonu ʻoki

Ma muli o ka ikaika o ka ikaika o ka pono hana, ka nui o ka hānai hānai ʻana, a me ka hānai ʻoki nui mai ka huli ʻana a i ka huli ʻana, koi ʻia ia e hana i ka mīkini hana wāwahi liʻiliʻi a koho i kahi hohonu ʻoki kūpono e like me ka hoʻohaʻahaʻa ʻana. Papa papa 1 i nā helu kūmole o nā manawa hānai a me ka ʻoki ʻana i ka hohonu no ka ʻoki ʻana o ka wili metric maʻamau.
