Pehea e hana ai ka ʻoki ʻoki laser?

.No ke aha i hoʻohana ʻia ai nā lasers no ka ʻoki ʻana?

"LASER", he acronym for Light Amplification by Stimulated Emission of Radiation, ua hoʻohana nui ʻia i nā ʻano āpau o ke ola, ke hoʻohana ʻia ka laser i ka mīkini ʻokiʻoki, loaʻa iā ia ka mīkini ʻoki me ka wikiwiki kiʻekiʻe, ka pollution haʻahaʻa, nā mea hoʻopau liʻiliʻi, a kahi wahi wela liʻiliʻi. I ka manawa like, hiki ke kiʻekiʻe ke kiʻekiʻe o ka mīkini hoʻololi photoelectric o ka mīkini ʻokiʻoki i ʻelua manawa o ka mīkini ʻoki carbon dioxide, a ʻo ka lōʻihi māmā o ka fiber laser he 1070 nanometers, no laila ʻoi aku ka kiʻekiʻe o ka absorption rate, ʻo ia hoʻi. ʻoi aku ka maikaʻi i ka wā e ʻoki ai i nā pā metala lahilahi. ʻO ka maikaʻi o ka ʻoki ʻana i ka laser e lilo ia i ʻenehana alakaʻi no ka ʻoki ʻana metala, i hoʻohana nui ʻia i ka ʻoihana mīkini a me ka ʻoihana hana, ʻo ka mea maʻamau ka ʻoki ʻana i ka metala, ʻoki ʻia i ke kahua automotive, etc.

.Pehea ka hana o ka mea oki laser?

I. Kuʻuna Hana Hana Laser

Hoʻopili ʻia ka kukuna laser i kahi wahi māmā me kahi anawaena liʻiliʻi loa (hiki ke emi mai ka liʻiliʻi ma mua o 0.1mm). I ke poʻo ʻoki ʻoki laser, e hele kēlā ʻano kukuna ikaika nui i loko o kahi lens kūikawā a i ʻole ke aniani curved, e lele i nā ʻaoʻao like ʻole, a ʻohi ʻia ma luna o ka mea metala e ʻoki ʻia. Ma kahi i ʻoki ʻia ai ke poʻo ʻoki laser, hoʻoheheʻe koke ka metala, hoʻoheheʻe ʻia, ablates, a hiki i kahi kikoʻī. Huhu ka metala a lilo i mau lua, a laila hoʻoheheʻe ʻia ka ea holo kiʻekiʻe ma o ka nozzle coaxial me ke kukui. Me ke kaomi ikaika o kēia kinoea, wehe ʻia ka metala wai, hana ʻia nā ʻāpana.

Hoʻohana nā mīkini ʻoki laser i ka optics a me ka mana helu kamepiula (CNC) e alakaʻi i ke kukui a i ʻole nā ​​​​mea, maʻamau e hoʻohana kēia ʻanuʻu i kahi ʻōnaehana neʻe e nānā i ka CNC a i ʻole G code o ke kumu e ʻoki ʻia ma luna o ka mea, e hoʻokō i ka ʻoki ʻana i nā ʻano like ʻole. .

II. ʻO nā kumu nui o ka hana laser

1) ʻoki hoʻoheheʻe laser

ʻO ka hoʻoheheʻe ʻana i ka laser e hoʻohana i ka ikehu o ka kukuna laser e wela a hoʻoheheʻe i ka mea metala, a laila e pīpī i ke kinoea non-oxidizing compressed (N2, Air, etc.) ma o ka nozzle coaxial me ka lāʻau, a wehe i ka metala wai me. ke kōkua o ke kaomi kinoea ikaika e hana i kahi ʻoki ʻoki.

Hoʻohana nui ʻia ka ʻoki hoʻoheheʻe ʻana i ka laser e ʻoki i nā mea non-oxidizing a i ʻole nā ​​metala reactive e like me ke kila kila, titanium, aluminika a me kā lākou mau ala.

2) ʻokiʻoki oxygen laser

ʻO ke kumu o ka ʻoki ʻana i ka oxygen laser e like me ka ʻoki oxyacetylene. Hoʻohana ia i ka laser e like me ke kumu preheating a me ke kinoea hana e like me ka oxygen e like me ke kinoea ʻoki. Ma kekahiʻaoʻao, hoʻopili ke kinoea i hoʻokuʻuʻia me ka metala, e hana ana i ka nui o ka wela o ka oxidation. Ua lawa kēia wela e hoʻoheheʻe i ka metala. Ma ka ʻaoʻao ʻē aʻe, puhi ʻia nā oxides hoʻoheheʻe ʻia a me ka metala hoʻoheheʻe ʻia mai loko mai o ka wahi pane, e hana ana i nā ʻoki i loko o ka metala.

Hoʻohana nui ʻia ka ʻoki oxygen laser no nā mea metala maʻalahi e like me ke kila kalapona. Hiki ke hoʻohana ʻia no ka hana ʻana i ke kila kila a me nā mea ʻē aʻe, akā ʻeleʻele a ʻeleʻele ka ʻāpana, a ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka ʻoki kinoea inert.
