Izinzuzo Zokushisela Nge-Laser Embonini Yobucwebe

Ukushisela nge-laserinikeza amandla aphezulu okushisela kanye nesivinini, kanye nesilinganiso esiphansi sokwenqatshwa, okwenza isetshenziswe kabanzi ekukhiqizeni kwesimanje. Embonini yobucwebe, uma kuqhathaniswa namasu okushisela endabuko, ukushisela nge-laser kunezinzuzo ezibalulekile.

1. Isivinini esiphezulu, amandla aphezulu, ukuhlanekezela okuphansi - akudingeki ukuqondisa noma ukuhlanza ngemuva kokushiswa
Isizathu esiyinhlokoabakhiqizi bobucwebeUkushisela nge-laser kwamukelwa kabanzi njengejubane layo elisheshayo lokushisela kanye nokuphambuka okuncane, kususa isidingo sokuqondisa nokuhlanza ngemuva kokushisela. Nakuba ukushisela nge-laser kushesha kunokushisela ilangabi lendabuko, umqhubi uvame ukubamba umsebenzi ngezandla noma ngezinto zokwakha, ukushisela ingxenye eyodwa ngesikhathi. Njengoba izindawo eziningi zokusebenza zokushisela nge-laser zobucwebe zincane futhi azikwazi ukucubungula amaqoqo amakhulu ngesikhathi esisodwa, isikhathi sokushisela singase sikhuphuke kancane. Kodwa-ke, ukuncipha komsebenzi wokuhlanza ngemva kokushisela kuqinisekisa isikhathi sokushisela. Ukushisela nge-laser kungenziwa ngaphansi kwesimo segesi esingenasici, kungashiyi amabala omlilo kumkhiqizo. Ngakho-ke, akukho ukugeleza okudingekayo, futhi akukho ukukhishwa kwe-acid okudingekayo ngemva kokushisela. Sekukonke, ukushisela nge-laser kuphumela ekusebenzeni kahle kokukhiqiza okuphezulu.

2. Kufanelekela izingxenye zokushisela ngokunemba, ukuqinisekisa ikhwalithi yomsebenzi.
Ngenxa yokuthi umsebe we-laser ungagxiliswa endaweni encane kakhulu futhi ubekeke kahle, ulungele ukukhiqizwa okuzenzakalelayo okuphezulu. Lokhu kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza, kunciphisa indawo ethintekile ekushiseni, futhi kugcina ukungcola kwe-weld kungenazo izinto ezingcolisayo, kuthuthukisa kakhulu ikhwalithi ye-weld futhi kunciphisa amazinga okukhubazeka. Isibonelo, lapho kushiswa ubucwebe be-14K alloy obunama-58% Au kanye no-2% Ag ngobuningi, isiliva liyashiswa, kunciphisa ubulukhuni bento kusukela cishe ku-HV 145 kuya cishe engxenyeni. Uma iwiswa kusukela ekuphakameni okhalweni iye phansi, ingase iqhekeke. Ngokusebenzisa ukushiswa kwe-laser okunamandla aphansi, okusheshayo, ukushisa kuyaqina, ngakho-ke umsebenzi awushiswa, ngaleyo ndlela ulondoloze amandla awo.

3. Ukunemba okuphezulu kokuhlanganiswa, okusiza ekuthuthukiseni izinqubo ezintsha zokukhiqiza ubucwebe.
Isingeniso sikaukushisela nge-laserUkungena embonini yobucwebe kushintshe ukucabanga komklamo wobucwebe bendabuko. Ngokushisela nge-laser, kungakhiqizwa izitayela ezikhethekile zesakhiwo. Esikhathini esidlule, lezi zakhiwo ezikhethekile zazinzima noma zingenakwenzeka ukuzifeza ngokushisela kwendabuko. Ukushisela nge-laser kungenziwa ezindaweni ezincane kakhulu, okwenza kube lula ukushisela izinhlobo ezahlukene zezinto ze-alloy ndawonye. Ngakho-ke, umbala noma isakhiwo phakathi kwezingxenye ezimbili singashintsha ngokuzumayo ngaphandle kokuxuba. Indawo yokusebenza encane yokushisela nge-laser ibangela umehluko ekumeni kwamanzi, ubuqotho bamalunga, kanye nosayizi wezinhlamvu endaweni ethintekile ukushisa uma kuqhathaniswa nokushisela kwendabuko.

4. Ukungaguquguquki okuhle kanye nokuqina.
Ngokuvamile, akudingeki insimbi yokugcwalisa noma i-flux - umsebenzi ungancibilikiswa endaweni bese ushintshwa ngqo.

5. Kwenza kube lula ukulungisa izingxenye.
Isibonelo, ukulungisa insimbi eduze kwamatshe ayigugu, ukususa imigodi yokukhipha, kanye nokushisela ezindaweni eziseduze no-0.2 mm ezingxenyeni eziyinkimbinkimbi, ezizwela ukushisa njengezihinji, ama-hooks, ama-clasps, kanye nezilungiselelo.

6. Akukho ukungcoliswa kwemvelo.
Ngesikhathi sokushisela nge-laser, akukho solder noma i-solvent esetshenziswayo, futhi akudingeki izinto zokuhlanza ngamakhemikhali, ngakho-ke akukho nkinga yokulahla imfucuza.

7. Igcina izinto zensimbi eziyigugu.
Ukushisela kwendabuko ngokuvamile kudinga ukujiya kwensimbi okungaba ngu-0.2 mm, kanti ukushisela nge-laser kungakunciphisa lokhu kube ngu-0.1 mm. Lokhu kunciphisa isisindo sento yobucwebe cishe ngo-35–40%, okubaluleke kakhulu emikhiqizweni eyenziwe ngogesi. Ukushisela nge-laser akugcini nje ngokusindisa izinto zensimbi eziyigugu kodwa futhi kusindisa nokushisela, futhi kuma-weld amaningi, izinhlobo ezahlukene zokushisela azidingeki.

8. Izici
Imishini yokushisela nge-laser evame ukusetshenziswa ekukhiqizeni ubucwebe inamandla amancane, inokuphepha okuphezulu, ubuncane, kanye nokuhamba kalula, okuvumela umqhubi ukuthi asebenze ngokunethezeka ngenkathi ehleli.
Umshini wokushisela we-laser ojwayelekile wobucwebe ungashisela ngokushesha, ngokuthembekile, nangokunembile izinsimbi eziningi kanye nama-alloy, yize ukusebenza kahle kuncike kakhulu ezimpahleni zezinto eziqondiwe. Ukuhlanganiswa okuqhubekayo noma ukulungiswa kwama-castings kungenziwa ngaphansi kokulawulwa okubonakalayo nge-laser pulses eyodwa noma ngaphezulu, ngokuvamile i-pulse ngayinye ihlala isikhathi esingu-1-20 ms. Ukusebenzisa i-microscope ye-stereo ene-crosshairs, indawo yokushisela ingabekwa kahle, futhi umsebenzi ungalungiswa kahle ngaphakathi kwenkambu yokubuka. Indawo yokusebenza ivame ukuba nomoya; ukufaka umoya noma igesi engasebenzi endaweni yokusebenza kunikeza ukupholisa, kanti igesi engasebenzi nayo ithuthukisa ikhwalithi yokushisela yama-alloy.

9. Ithonya Lezinto Ezihlanganisiwe Kumphumela Wokushisela Nge-Laser
Izinto ze-alloy ezahlukene zinemiphumela ehlukile yokushisela nge-laser. Ngaphansi kwamapharamitha okulawula afanayo omshini wokushisela nge-laser kanye nokushisa okufanayo okudluliswa nge-pulse yokushisela, umphumela wokuncibilika nge-pulse uyahluka ngenxa yokwehluka kwesilinganiso sokushisa okumuncwa (kunokuba kuboniswe) ubuso bezinto ze-alloy. Izici ezithile ezithonyayo zifaka phakathi umthamo wokushisa kusukela ekushiseni kwegumbi kuya endaweni yokuncibilika, indawo yokuncibilika, ukushisa okucashile kokuhlanganiswa, kanye nokuqhuba ukushisa. Izinto ezahlukene zine-conductivity ehlukene yokushisa, amazinga okushisa okuncibilika, kanye nokushisa okucashile kokwakheka kwekristalu. Zihlangene, lezi zinto zithinta kakhulu amandla adingekayo ukuze kushiselwe ngempumelelo. Ukumuncwa okwanele kokushisa ebusweni kuyadingeka ukuze kushiselwe ngempumelelo.
