Kune akasiyana nzira dzekuchenesa muindasitiri yekuchenesa yechinyakare, mazhinji ayo anoshandisa makemikari ejenti uye mechanicha nzira dzekuchenesa.Nhasi, sezvo nyika yangu mitemo yekudzivirira kwezvakatipoteredza ichiwedzera kuomarara uye kuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza uye kuchengetedzwa kuri kuwedzera, mhando dzemakemikari anogona kushandiswa mukuchenesa kugadzirwa kwemaindasitiri anozove mashoma uye mashoma.
Nzira yekuwana nzira yekuchenesa uye isina kukuvadza yekuchenesa mubvunzo watinofanira kufunga nezvazvo.Laser yekuchenesa ine maitiro easina-abrasive, asingabatanidzi, hapana thermal effect uye akakodzera zvinhu zvezvinhu zvakasiyana-siyana.Inofungidzirwa kuti ndiyo yakavimbika uye inoshanda mhinduro.Panguva imwecheteyo, michina yekuchenesa laser inogona kugadzirisa matambudziko asingagone kugadziriswa nenzira dzechinyakare dzekuchenesa.
Laser Yekuchenesa Dhiagiramu
Sei laser inogona kushandiswa kuchenesa?Sei zvisingakonzere kukanganisa kwezvinhu zviri kucheneswa?Kutanga, ngatinzwisise chimiro che laser.Kuzvitaura zviri nyore, ma lasers haana kusiyana nechiedza (chiedza chinooneka uye chiedza chisingaoneki) chinotitevera chakatipoteredza, kunze kwekuti lasers anoshandisa resonant cavities kutarisa chiedza nenzira imwe chete, uye ane marefu akareruka, kuwirirana, nezvimwewo. zviri nani, saka mune dzidziso, chiedza chewavelengths ese chinogona kushandiswa kugadzira lasers.Nekudaro, muchokwadi, hapana midhiya yakawanda inogona kunakidzwa, saka kugona kuburitsa yakagadzikana laser mwenje masosi akakodzera kugadzirwa kwemaindasitiri ishoma.Anonyanya kushandiswa angangodaro Nd: YAG laser, carbon dioxide laser uye excimer laser.Nekuti Nd: YAG laser inogona kutapurirana kuburikidza neoptical fiber uye yakanyanya kukodzera kumaindasitiri maapplication, inowanzoshandiswa mukuchenesa laser.
Zvakanakira:
Kuenzaniswa nemaitiro echinyakare ekuchenesa akadai semechanicha friction yekuchenesa, makemikari corrosion kuchenesa, mvura-yakasimba yakasimba kuchenesa kuchenesa, uye yakakwirira-frequency ultrasonic kuchenesa, laser kuchenesa kune zvakanakira zviri pachena.
1. Laser kuchenesa inzira yekuchenesa "yegirini" yekuchenesa, pasina kushandisa chero makemikari uye kuchenesa mhinduro, kuchenesa pasi tsvina inongova poda yakasimba, diki diki, iri nyore kuchengeta, inoshandiswa zvakare, inogona kugadzirisa nyore dambudziko rekusvibiswa kwezvakatipoteredza kunokonzerwa. nekuchenesa makemikari;
2. Nzira dzechinyakare dzekuchenesa dzinowanzosangana nekuchenesa, kuchenesa pamusoro pechinhu chine simba remagetsi, kukuvadzwa kwepamusoro pechinhu kana svikiro rekuchenesa rakasungirirwa pamusoro pechinhu chinofanira kucheneswa, hachikwanise kubviswa, zvichikonzera yechipiri. kusvibiswa, kucheneswa kwelaser kweasina-abrasive uye isiri-yekubata kuitira kuti matambudziko aya agadziriswe;
3. Laser inogona kuparadzirwa kuburikidza nefiber optics, ine marobhoti uye marobhoti, zviri nyore kuti zvibudirire kureba kure kushanda, inogona kuchenesa nzira dzechinyakare hazvisi nyore kusvika kune zvikamu, izvo mune dzimwe nzvimbo dzine njodzi kushandisa zvinogona kuve nechokwadi chekuchengetedzwa kwevashandi;
4. Laser kuchenesa kunoshanda uye kunochengetedza nguva;
Mitemo
Iyo nzira ye pulsed fiber laser yekuchenesa inoenderana nehunhu hwechiedza pulses inogadzirwa nelaser uye yakavakirwa pane iyo photophysical reaction inokonzerwa nekudyidzana pakati peiyo yakakwirira-yakasimba danda, iyo pfupi-pulse laser uye yakasvibiswa layer.The physical musimboti inogona kupfupikiswa sezvinotevera:
Laser Yekuchenesa Schematic
a) Danda rinoburitswa nelaser rinotorwa neiyo yakasvibiswa layer iri pamusoro kuti irapwe.
b)Kutorwa kwesimba rakakura kunoumba plasma inokurumidza kukura (yakanyanya ionized isina kugadzikana gasi), iyo inoburitsa kuvhunduka.
c) Iko kuvhunduka kunoita kuti zvinosvibisa zviparare uye zvirambwe.
d) Hupamhi hwekupuruzira kwechiedza hunofanirwa kuve hupfupi zvakakwana kudzivirira inoparadza kupisa kuvaka-kumusoro panzvimbo yakarapwa.
e)Kuedza kwakaratidza kuti plasma inogadzirwa pasimbi kana paine oxide pamusoro.
Zvishandiso zvinoshanda:
Laser kuchenesa inogona kushandiswa kuchenesa kwete chete organic zvinosvibisa, asiwo inorganic zvinhu, kusanganisira simbi ngura, simbi zvimedu, huruva uye zvichingodaro.Izvi zvinotevera zvinotsanangura mamwe maapplication anoshanda, aya matekinoroji akakura kwazvo uye akashandiswa zvakanyanya.
Laser tire yekuchenesa dhizaini
1. Kucheneswa kwezviumbwa
Nemazana emamiriyoni ematayi anogadzirwa gore rega rega nevanogadzira matayi pasi rese, kucheneswa kwematayi panguva yekugadzira kunofanira kukurumidza uye kwakavimbika kuchengetedza nguva.
Laser yekuchenesa tayi mold tekinoroji yakashandiswa muhuwandu hukuru hweindasitiri yematayi muEurope neUnited States, kunyangwe mari yekutanga yekudyara yakakwira, asi inogona kuchengetedza nguva yekumira, kudzivirira kukuvadzwa kwekuumbwa, kuchengetedza basa uye kuchengetedza zvigadzirwa pa budiriro dzakaitwa nekukurumidza kupora.
2. Kucheneswa kwezvombo nemidziyo
Laser yekuchenesa tekinoroji inoshandiswa zvakanyanya mukugadzirisa zvombo.Iko kushandiswa kwelaser yekuchenesa sisitimu kunogona kuita uye nekukurumidza kubvisa ngura uye zvinosvibisa, uye inogona kusarudza yekubvisa saiti kuti uone otomatiki yekuchenesa.Nekucheneswa kwelaser, kwete chete hutsanana huri pamusoro peiyo yemakemikari ekuchenesa maitiro, asi hapana kana kukuvadzwa pamusoro pechinhu.
3. Kubviswa kwepende yendege yekare
MuEurope laser yekuchenesa masisitimu agara achishandiswa muindasitiri yendege.Kumusoro kwendege kunofanira kupendwazve pashure penguva yakati, asi pendi yekare inoda kubviswa zvachose isati yapendwa.
Nzira dzechinyakare dzekubvisa pendi dzemakina dzinowanzo kuvadza pamusoro pesimbi yendege, zvichiunza njodzi inogona kuitika pakubhururuka kwakachengeteka.Kana akawanda laser ekuchenesa masisitimu akashandiswa, iyo pendi layer iri pamusoro peA320 Airbus inogona kubviswa zvachose mukati memazuva matatu pasina kukuvadza pamusoro pesimbi.
4. Kuchenesa muindasitiri yemagetsi
Laser oxide kubviswa kweindasitiri yemagetsi: Indasitiri yemagetsi inoda kusvibiswa kwepamusoro-chaiyo uye inonyanya kukodzera kubviswa kwelaser oxide.Pamberi pedunhu bhodhi soldering, mapini echikamu anofanirwa kuve akanyatso de-oxidized kuti ave nechokwadi chekusangana kwemagetsi, uye mapini haafanire kukuvadzwa panguva yekubvisa tsvina.Laser yekuchenesa inosangana nezvinodiwa zvekushandisa uye inoshanda zvekuti chete laser exposure inodiwa kune imwe pini.
