Solder, ngati chinthu chofunikira kwambiri cholumikizira m'magawo ambiri monga zamagetsi, zamagalimoto, zakuthambo, ndi zina zambiri, mtundu wake ndi magwiridwe ake zimakhudza mwachindunji kudalirika ndi kukhazikika kwazinthu. Ndi kupita patsogolo kosalekeza kwaukadaulo, zofunikira pakuyera, microstructure, ndi magwiridwe antchito a solder zikuchulukirachulukira. Monga zida zapamwamba zoponyera zitsulo, makina opangira zitsulo zopingasa zopingasa pang'onopang'ono akopa chidwi pamakampani ogulitsa malonda, ndikupereka njira yabwino yopangira solder yapamwamba kwambiri.

1,Ntchito mfundo yavacuum yopingasa mosalekeza kuponya makina

Makina oponyera osasunthika mosalekeza amapangidwa makamaka ndi ng'anjo, kristalo, chida chokoka billet, makina opumulira, ndi mbali zina. Choyamba, ikani zinthu zogulitsira mu ng'anjo yosungunuka ndikutenthetsa kuti zifike kutentha kwamadzi koyenera. Kenako, malo oponyeramo amasamutsidwa kumlingo wina kudzera mu vacuum system kuti achepetse kusakanikirana kwa zonyansa za gasi. Pansi pa mphamvu yokoka ndi kuthamanga kwakunja, solder yamadzimadzi imalowa mu kristalo yopingasa, yomwe imakhazikika ndi madzi ozungulira kuti pang'onopang'ono ikhale yolimba komanso yonyezimira pakhoma lake lamkati, ndikupanga chipolopolo. Ndi kutsika pang'onopang'ono kwa chipangizo choponyera, solder yatsopano yamadzimadzi imawonjezeredwa mosalekeza mu crystallizer, ndipo chipolopolo cholimba chokhazikika chimatulutsidwa mosalekeza, motero amakwaniritsa kuponya kosalekeza.

vacuum yopingasa mosalekeza kuponya makina

2,Ubwino wa Vacuum Horizontal Continuous Casting Machine

(1）Sinthani chiyero cha solder

Kuponyera m'malo opanda mpweya kumatha kulepheretsa zonyansa za mpweya monga mpweya ndi nayitrogeni kulowa mu solder, kuchepetsa mapangidwe a oxide inclusions ndi pores, kusintha kwambiri chiyero cha solder, ndikuwonjezera kunyowa kwake ndi kutuluka kwake panthawi yowotcherera, potero kuwongolera. ubwino wa welded olowa.

(2）Kupititsa patsogolo microstructure ya solder zipangizo

Pa vakuyumu yopingasa mosalekeza kuponyera, ndi solidification mlingo wa solder madzi ndi yunifolomu, ndi mlingo kuzirala ndi controllable, amene amathandiza kupanga yunifolomu ndi wabwino njere dongosolo ndi kuchepetsa tsankho zochitika. Kapangidwe kakapangidwe ka bungwe kameneka kamapangitsa kuti makina a solder akhale okhazikika, monga kulimba kwamphamvu ndi kutalika, zomwe zimakonzedwa bwino ndikukwaniritsa zovuta zogwiritsa ntchito popanga solder.

(3）Mwachangu mosalekeza kupanga

Poyerekeza ndi njira zoponyera zachikhalidwe, makina oponyera osasunthika osasunthika amatha kukwaniritsa kupanga kosalekeza komanso kosalekeza, kuwongolera bwino kwambiri kupanga. Pa nthawi yomweyo, ali mkulu mlingo wa zochita zokha, kuchepetsa masitepe ntchito pamanja, kutsitsa ntchito mwamphamvu ndi mtengo kupanga, ndi kupanga ndondomeko yokhazikika ndi odalirika, amene amathandiza kulamulira mosasinthasintha khalidwe mankhwala.

(4）Chepetsani zinyalala zakuthupi

Chifukwa cha kuponyedwa kosalekeza ndikuwongolera bwino kukula ndi mawonekedwe a billet, poyerekeza ndi njira zina zoponyera, zimatha kugwiritsa ntchito bwino zida zopangira, kuchepetsa zinyalala zakuthupi zomwe zimayambitsidwa ndi kudula, machilango a makina, ndi zina zambiri, kuwongolera kuchuluka kwa magwiritsidwe ntchito. zopangira, ndi kuchepetsa mtengo kupanga.

3,Ntchito zenizeni m'makampani a solder

(1）Njira yopanga

Pakupanga solder, sitepe yoyamba ndiyo kusakaniza zosakaniza zofunika za solder ndikuwonjezera zopangira zokonzedwa kung'anjo ya vacuum yopingasa mosalekeza. Yambitsani dongosolo la vacuum, kuchepetsa kuthamanga mkati mwa ng'anjo kuti mukhale ndi mpweya wabwino, nthawi zambiri pakati pa makumi a pascals ndi mazana a pascals, ndiye kutentha ndi kusungunula solder ndi kusunga kutentha kokhazikika. Sinthani liwiro la kuponyera ndi kuchuluka kwa madzi ozizira a crystallizer kuonetsetsa kuti solder yamadzimadzi imalimba mofanana mu crystallizer ndipo imatulutsidwa mosalekeza, ndikupanga mtundu wina wa solder billet. Chosowekacho chimakonzedwa kudzera mu kugubuduza kotsatira, kujambula ndi njira zina zopangira kuti apange mawonekedwe osiyanasiyana ndi mafotokozedwe azinthu zogulitsira, monga waya wowotcherera, chingwe chowotcherera, phala la solder, ndi zina zambiri, kuti akwaniritse zosowa zowotcherera m'magawo osiyanasiyana.

(2）Kupititsa patsogolo ubwino wa zipangizo za solder

Kutenga Sn Ag Cu wopanda lead solder yemwe amagwiritsidwa ntchito kwambiri pamakampani opanga zamagetsi monga mwachitsanzo, akapangidwa pogwiritsa ntchito makina opumira opingasa osalekeza, zomwe zili mu solder zitha kuwongoleredwa motsika kwambiri, kupewa zonyansa monga malata. chifukwa cha makutidwe ndi okosijeni ndikuwongolera magwiridwe antchito a solder. Pa nthawi yomweyo, yunifolomu bungwe dongosolo zimathandiza kuti solder kudzaza bwino mipata yaing'ono olowa solder pa ndondomeko yaying'ono soldering wa zigawo zikuluzikulu pakompyuta, kuchepetsa kuwotcherera zilema monga pafupifupi soldering ndi bridging, ndi kuwongolera kuwotcherera kudalirika ndi ntchito magetsi zinthu zamagetsi.

Mu njira yowotcha yamakampani amagalimoto, chifukwa champhamvu champhamvu cha aluminiyamu yochokera ku solder, solder yopangidwa ndi vacuum yopingasa mosalekeza makina oponyera amakhala ndi mphamvu zabwinoko komanso kukana dzimbiri. Mapangidwe ake a yunifolomu a tirigu amatsimikizira kukhazikika kwa solder panthawi yotentha kwambiri, yomwe imatha kugwirizanitsa mwamphamvu zigawo zamagalimoto ndikuwongolera ntchito yonse ndi moyo wautumiki wa zigawo zamagalimoto.

(3）Zitsanzo za ntchito

Kampani yodziwika bwino yopanga solder yayambitsa avacuum mlingo mosalekeza kuponya makina, yomwe yawonjezera chiyero cha mankhwala ake opangira malata kuchokera ku 98% kufika pa 99.5%, ndipo yachepetsa kwambiri zomwe zili mu oxide inclusions. Pakugwiritsa ntchito kuwotcherera pama board amagetsi, kulephera kwa kuwotcherera kwatsika kuchokera pa 5% mpaka kuchepera 1%, kupititsa patsogolo kwambiri kupikisana pamsika wazinthu. Panthawi imodzimodziyo, chifukwa cha kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu.

4,Chiyembekezo cha chitukuko

Ndi chitukuko chofulumira cha mafakitale monga zamagetsi, mphamvu zatsopano, ndi zipangizo zamakono zopangira zipangizo zamakono, zofunikira za khalidwe ndi ntchito za zipangizo zogulitsira zidzapitirira kuwonjezeka. Makina a vacuum yopingasa mosalekeza ali ndi mwayi wogwiritsa ntchito kwambiri pamsika wa solder chifukwa cha zabwino zake zapadera. M'tsogolomu, ndi kupita patsogolo kosalekeza kwa zipangizo zamakono zopangira zida, makina ake otsekemera adzakhala opambana komanso okhazikika, mlingo wa kayendetsedwe ka makina opangidwa ndi makinawo udzakhalanso bwino, ndipo ndondomeko yolondola kwambiri yoyang'anira magawo ikhoza kutheka, kupanga khalidwe lapamwamba komanso makonda kwambiri solder. mankhwala. Pakalipano, ndi zofunikira kwambiri zachilengedwe, ubwino wa vacuum mlingo mosalekeza kuponyera makina kuchepetsa kuwononga mphamvu ndi mpweya woipa adzawapanga kukhala ukadaulo wofunika kuthandiza chitukuko zisathe za solder makampani.

5, Mapeto

Kugwiritsa ntchito vacuum yopingasa mosalekeza kuponya makina mumsika wa solder kumapereka chitsimikizo champhamvu chapamwamba komanso kuchita bwino kwambiri kwa solder. Mwa kukonza chiyero cha solder, kupititsa patsogolo dongosolo la bungwe, kukwaniritsa kupanga kosalekeza, ndi kuchepetsa ndalama, kuwonjezeka kwa kufunikira kwa ogulitsa malonda amakono kwakwaniritsidwa. Ndi chitukuko chosalekeza ndi kupititsa patsogolo kwa teknoloji, ntchito yake mu malonda a solder idzakhala yowonjezereka komanso yozama, kulimbikitsa chitukuko cha malonda a solder ku khalidwe lapamwamba, ntchito zapamwamba, ndi chitetezo cha chilengedwe chobiriwira, kupereka zowonjezereka komanso zodalirika. zida zolumikizira zamafakitale ambiri omwe amadalira kulumikizana ndi solder, ndikulimbikitsa kukweza kwaukadaulo ndikupita patsogolo kwaunyolo wonse wamakampani.

Patsogolo pakukula kwamakampani ogulitsa malonda, mabizinesi akuyenera kuzindikira kuthekera ndi mtengo wa makina opopera osasunthika, kuyambitsa mwachangu ndikugwiritsa ntchito ukadaulo wapamwambawu, kulimbikitsa luso laukadaulo ndi kukhathamiritsa kwazinthu, kupititsa patsogolo mpikisano wawo wamsika mosalekeza, komanso kulimbikitsa wogulitsa. makampani kupita ku gawo latsopano lachitukuko.
