ʻO Burrs kahi pilikia maʻamau i ka hana metala. ʻAʻohe o nā mea hana pololei i hoʻohana ʻia, e hoʻokumu ʻia nā burrs ma ka huahana hope. He koena metala keu lākou i hana ʻia ma nā ʻaoʻao o ka mea i hana ʻia ma muli o ka deformation plastic, ʻoi aku hoʻi i nā mea me ka ductility maikaʻi a paʻakikī paha.
ʻO nā ʻano nui o nā burr e pili ana i nā burrs flash, nā burrs koi, a me nā splashes. ʻAʻole kūpono kēia mau koena metala i nā koi hoʻolālā huahana. I kēia manawa,ʻaʻohe ala kūpono e hoʻopau loa i kēia pilikia i ka hana hana. No laila, pono nā mea ʻenekinia i ka wehe ʻana i nā burrs i nā pae hope e hōʻoia i ka huahana e hoʻokō i nā koi hoʻolālā. Loaʻa nā ʻano hana a me nā mea hana no ka wehe ʻana i nā burrs mai nā huahana like ʻole.
Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia nā ʻano o ka wehe ʻana i nā burrs i ʻehā mau ʻāpana:
1. Papa koʻikoʻi (pili paʻakikī)
Aia kēia ʻāpana i ka ʻokiʻoki, ka wili ʻana, ka waiho ʻana, a me ka ʻōpala.
2. Papa maʻamau (pili palupalu)
Aia kēia ʻāpana i ka wili kāʻei, ka lapping, ka wili elastic, ka wili huila, a me ka polishing.
3. Papa pololei (pili hikiwawe)
Aia kēia ʻāpana i ka flushing, ka hana electrochemical, electrolytic grinding, a me ka ʻōwili.
4. Mākaʻikaʻi-pololei (pili pololei)
Aia kēia ʻāpana i nā ʻano hana deburring like ʻole, e like me ka abrasive flow deburring, magnetic grinding deburring, electrolytic deburring, thermal deburring, a me ka radium dense me ka ultrasonic deburring ikaika. Hiki i kēia mau ʻano hana ke hoʻokō i ka pololei o ka hana ʻāpana kiʻekiʻe.
Ke koho ʻana i kahi ʻano deburring, he mea nui e noʻonoʻo i nā kumu like ʻole, me nā waiwai waiwai o nā ʻāpana, ko lākou ʻano hoʻolālā, ka nui, a me ka pololei, a e nānā pono i nā loli o ka ʻili o ka ʻili, ka hoʻomanawanui dimensional, deformation, a me ke koena. kaumaha.
ʻO ka electrolytic deburring kahi hana kemika i hoʻohana ʻia e wehe i nā burrs mai nā ʻāpana metala ma hope o ka mīkini ʻana, wili, a i ʻole ke kahakaha ʻana. Hiki iā ia ke hoʻopuni a chamfer i nā ʻaoʻao ʻoi o nā ʻāpana. Ma ka ʻōlelo Pelekania, kapa ʻia kēia ʻano ʻo ECD, kahi e kū nei no ka Electrolytic Capacitive Discharge. I ka wā o ke kaʻina hana, hoʻokomo ʻia kahi cathode mea hana (i hana mau ʻia me ke keleawe) kokoke i ka ʻāpana burred o ka mea hana me kahi ākea o 0.3-1 mm ma waena o lākou. Hoʻopili ʻia ka ʻāpana conductive o ka cathode mea hana me ka lihi o ka burr, a uhi ʻia nā ʻaoʻao ʻē aʻe me kahi papa insulating e hoʻokau i ka hana electrolytic ma ka burr.
Hoʻopili ʻia ka cathode mea hana i ka pou maikaʻi ʻole o kahi lako mana DC, ʻoiai ua pili ka mea hana i ka pou maikaʻi. ʻO kahi electrolyte haʻahaʻa haʻahaʻa (maʻamau he sodium nitrate a i ʻole sodium chlorate aqueous solution) me ke kaomi o 0.1-0.3MPa e kahe ana ma waena o ka mea hana a me ka cathode. Ke hoʻohuli ʻia ka mana DC, hoʻoneʻe ʻia nā burrs e ka hoʻoheheʻe anode a lawe ʻia e ka electrolyte.
Ma hope o ka hoʻopau ʻana, pono e hoʻomaʻemaʻe ʻia ka mea hana a pale ʻia no ka mea ʻino ka electrolyte i kekahi ʻano. He kūpono ka deburring Electrolytic no ka wehe ʻana i nā burrs mai nā lua keʻa huna a i ʻole nā ʻāpana ʻano paʻakikī a ʻike ʻia no kāna hana hana kiʻekiʻe, maʻamau e lawe wale i nā kekona a i ʻumi mau kekona e hoʻopau i ke kaʻina hana. Hoʻohana maʻamau ʻia kēia ʻano no ka wehe ʻana i nā pahu, nā splines, nā koʻokoʻo hoʻohui, nā kino valve, nā puka ʻaila crankshaft, a no ka hoʻopuni ʻana i nā kihi ʻoi. Eia nō naʻe, ʻo kahi drawback o kēia ʻano hana ʻo ia ka pili ʻana o ka wahi a puni ka burr e ka electrolysis, e lilo ai ka ʻili i kona ʻālohilohi mua a hiki ke hoʻopilikia i ka pololei o ke ana.
Ma waho aʻe o ka electrolytic deburring, aia kekahi mau ʻano hana deburring kūikawā:
1. Kahe palaoa abrasive i deburr
ʻO ka ʻenehana hana hoʻoheheʻe abrasive kahi ala hou no ka hoʻopau maikaʻi ʻana a me ka deburring i hoʻomohala ʻia ma waho i ka hopena o 1970s. He mea maikaʻi loa ia no ka wehe ʻana i nā burrs i nā pae hope o ka hana. Eia naʻe, ʻaʻole kūpono ia no ka hoʻoponopono ʻana i nā puka liʻiliʻi, lōʻihi, a i ʻole nā mea hao i pani ʻia i lalo.
2. Mākēneki wili e deburr
ʻO ka wili magnetic no ka deburring i hoʻokumu ʻia ma ka Soviet Union mua, Bulgaria, a me nā ʻāina ʻē aʻe o ʻEulopa Hikina i ka makahiki 1960. Ma ka waena o 1980s, ua alakaʻi ʻia ka noiʻi hohonu e pili ana i kāna mīkini a me ka noi ʻana e Niche.
I ka wā o ka wili ʻana, hoʻokomo ʻia ka mea hana i loko o ke kahua magnetic i hana ʻia e ʻelua mau pou magnetic. Hoʻokomo ʻia ka abrasive magnetic i loko o ke āpau ma waena o ka mea hana a me ka pole magnetic, a ua hoʻonohonoho pono ʻia ka abrasive ma ke ala o ka laina kahua magnetic ma lalo o ka hana a ka mana magnetic e hana ai i kahi pulupulu palupalu palupalu a paʻa. Ke hoʻololi ka mea hana i ke kumu i loko o ke kahua magnetic no ka haʻalulu axial, e neʻe ka mea hana a me ka mea abrasive, a ʻo ka pulupulu abrasive e wili i ka ʻili o ka mea hana.
Hiki i ke kaʻina wili magnetic me ka maikaʻi a me ka wikiwiki i nā ʻāpana a deburr, a kūpono i nā ʻāpana o nā mea like ʻole, nā ʻano nui, a me nā hale like ʻole. He ʻano hoʻopau me ka haʻahaʻa haʻahaʻa, ka hana kiʻekiʻe, ka hoʻohana ākea, a me ka maikaʻi maikaʻi.
I kēia manawa, hiki i ka ʻoihana ke wili a hoʻopau i nā ʻaoʻao o loko a me waho o ka rotator, nā ʻāpana pālahalaha, nā niho niho, nā profile paʻakikī, a me nā mea ʻē aʻe.
3. Hoʻopau wela wela
ʻO ka Thermal Deburring (TED) kahi hana e hoʻohana ai i ka hydrogen, oxygen, a i ʻole ka hui ʻana o ke kinoea maoli a me ka oxygen e puhi i nā burrs i nā wela kiʻekiʻe. Hoʻokomo ʻia ke ʻano o ka hoʻokomo ʻana i ka oxygen a me ke kinoea maoli a i ʻole ka oxygen wale nō i loko o kahi pahu i pani ʻia a hoʻā ʻia ma o kahi pahu kukui, e hoʻohū ai ka hui ʻana a hoʻokuʻu i ka nui o ka ikehu wela e wehe i nā burrs. Eia naʻe, ma hope o ka puhi ʻia ʻana o ka mea hana e ka pahū ʻana, e pili ka pauka oxidized i ka ʻili o kaNā huahana CNCa pono e hoʻomaʻemaʻe ʻia a ʻai ʻia paha.
4. Miradium ikaika ultrasonic deburring
Ua lilo ka ʻenehana deburring ultrasonic ikaika a Milarum i mea kaulana i nā makahiki i hala iho nei. Hāʻawi ia i ka hoʻomaʻemaʻe hoʻomaʻemaʻe ʻana he 10 a 20 mau manawa kiʻekiʻe ma mua o nā mea hoʻomaʻemaʻe ultrasonic maʻamau. Hoʻolālā ʻia ka pahu me nā lua i hoʻokaʻawale ʻia a paʻa, e ʻae i ke kaʻina ultrasonic e hoʻopau ʻia i loko o 5 a 15 mau minuke me ka ʻole o ka pono o nā mea hoʻomaʻemaʻe.
Eia nā ala maʻamau he ʻumi e hoʻopau ai:
1) Hoʻopau lima lima
Hoʻohana maʻamau ʻia kēia ʻano e nā ʻoihana maʻamau, e hoʻohana ana i nā faila, sandpaper, a me nā poʻo wili e like me nā mea kōkua. Loaʻa nā faila manual a me nā mea hana pneumatic.
He kiʻekiʻe ke kumukūʻai hana, a hiki ke hoʻomaikaʻi ʻia ka maikaʻi, ʻoiai ke wehe ʻana i nā lua keʻa paʻakikī. ʻAʻole koi nui nā koi ʻenehana no nā limahana, kūpono ia i nā huahana me nā burrs liʻiliʻi a me nā hale maʻalahi.
2) Make deburring
Hoʻohana ʻia ka die hana no ka deburring me ka paʻi punch. Loaʻa iā ia kahi uku hana kūikawā no ka make (me ka make ʻinoʻino a me ka make stamping maikaʻi) a pono paha ke hana ʻana i kahi make. ʻOi aku ka maikaʻi o kēia ʻano hana no nā huahana me nā ʻāpana hoʻokaʻawale ʻole, a hāʻawi ia i nā hopena maikaʻi aʻe a me nā hopena deburring i hoʻohālikelike ʻia me ka hana lima.
3) ʻO ka wili ʻana i ka deburr
Aia kēia ʻano deburring i nā ʻano e like me ka vibration a me ka sandblasting drums, a hoʻohana mau ʻia e nā ʻoihana. Eia nō naʻe, ʻaʻole hiki iā ia ke wehe loa i nā hemahema a pau, e koi ana i ka hoʻopau lima a i ʻole ka hoʻohana ʻana i nā ʻano hana ʻē aʻe e loaʻa ai kahi hopena maʻemaʻe. Ua kūpono kēia ʻano no ka liʻiliʻinā mea hoʻohulihana ʻia ma ka nui.
4) Hoʻokuʻu i ka deburring
Hoʻohana ʻia ka hoʻoluʻu e hoʻopau koke i nā burrs, a laila hoʻokuʻu ʻia ka projectile e wehe i nā burrs. ʻO ke kumukūʻai o nā mea hana ma kahi o ʻelua a ʻekolu haneli kaukani kālā a kūpono i nā huahana me nā mānoanoa pā liʻiliʻi a me nā liʻiliʻi liʻiliʻi.
5) Wela blast deburring
ʻO ka deburring ikehu wela, ka mea i kapa ʻia ʻo explosion deburring, e pili ana i ke kuhikuhi ʻana i ke kinoea i hoʻopaʻa ʻia i loko o ka umu ahi a pahū, me ka hopena o ka ikehu i hoʻohana ʻia e hoʻopau a wehe i nā burrs.
He kumu kūʻai kēia ʻano, paʻakikī ʻenehana, a hiki ʻole ke alakaʻi i nā hopena ʻaoʻao e like me ka ʻōpala a me ka deformation. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana kikoʻī kiʻekiʻe, ʻoi loa i nā ʻoihana e like me ka automotive a me ka aerospace.
6) Engraving machine deburring
Kūʻai kūpono nā mea hana (ʻumi tausani) a kūpono i nā huahana me kahi hoʻolālā spatial maʻalahi a me kahi kūlana deburring maʻamau.
7) Hoʻopau kemika
Ma muli o ke kumu o ka hopena electrochemical, lawe ʻia ka hana deburring a koho ʻia ma nā ʻāpana metala.
He kūpono kēia kaʻina hana no ka wehe ʻana i nā burrs i loko e paʻakikī e hoʻopau, a me nā burr liʻiliʻi (emi iho ma lalo o ʻehiku mau uea i ka mānoanoa) mai nā huahana e like me nā kino pump a me nā kino valve.
8) Electrolytic deburring
ʻO ka mīkini Electrolytic kahi ala e hoʻohana ai i ka electrolysis e wehe i nā burrs mai nā ʻāpana metala. ʻO ka electrolyte i hoʻohana ʻia i kēia kaʻina hana he corrosive, a ke kumu ia i ka electrolysis ma kahi kokoke i ka burr, hiki ke hopena i ka nalo ʻana o ka luster mua o ka ʻāpana a hiki ke hoʻopilikia i kona kikoʻī.
Ua kūpono ka deburring electrolytic no ka wehe ʻana i nā burrs ma nā wahi huna o nā lua keʻa a i ʻoleʻāpana hoʻoleime nā ʻano paʻakikī. Hāʻawi ia i ka hana hana kiʻekiʻe, me nā manawa deburring maʻamau mai kahi mau kekona a i ʻumi kekona. He kūpono kēia ʻano no ka wehe ʻana i nā mea hana, nā koʻokoʻo hoʻohui, nā kino valve, nā puka kaapuni ʻaila crankshaft, a no ka hoʻopuni ʻana i nā kihi ʻoi.
9) ʻO ka hoʻoheheʻe ʻana i ka wai jet kiʻekiʻe
Ke hoʻohana ʻia ka wai e like me ke ʻano, hoʻohana ʻia kona ikaika koke e hoʻopau i nā burrs a me nā uila ma hope o ka hana ʻana. Kōkua kēia ʻano hana e hoʻokō i ka pahuhopu o ka hoʻomaʻemaʻe.
He kumukūʻai nā mea hana a hoʻohana nui ʻia i ka ʻoihana kaʻa a me nā ʻōnaehana hoʻokele hydraulic o nā mīkini hana.
10) Ultrasonic deburring
Hoʻokumu nā hawewe kani ultrasonic i ke kaomi kiʻekiʻe e hoʻopau i nā burrs. Hoʻohana nui ʻia no ka microscopic burrs; inā makemake lākou i ka nānā ʻana me kahi microscope, hiki ke hoʻohana ʻia ke ultrasound no ka wehe ʻana.
Inā makemake ʻoe e ʻike hou aku a nīnau paha, e ʻoluʻolu e leka uilainfo@anebon.com
Mea hana o China Hardware a me nā ʻāpana prototyping, no laila ke hana mau nei ʻo Anebon. Kūleʻa mākou i ke kūlana kiʻekiʻeNā huahana mīkini CNCa ua ʻike i ke koʻikoʻi o ka mālama ʻana i ke kaiapuni; ʻO ka hapa nui o nā mea kūʻai he pollution-free, nā mea pili i ke kaiapuni, a hoʻohana hou mākou iā lākou ma ke ʻano he hopena.
