Umgca weMveliso yokuMngunda
Iibhloko zentsimbi zifika njengeebhilithi ezixande. Ibanga leP20 lemiqulu yemveliso eqhelekileyo. Isatifikethi semathiriyeli sibonisa ubulukhuni malunga ne-28-32 HRC pre{7}}bulukhuni ukusuka kwilitye lokusila. Akukho nyango lobushushu olufunekayo phambi komatshini. Kwizixhobo eziphezulu ezilindeleke ukuba ziqhube imijikelezo ye-500,000 edlulileyo, ivenkile itshintshela kwi-H13 okanye i-S136 engenasici. Ezi zifuna ukuqina emva komatshini obunzima, okongeza iveki kwishedyuli kunye ne-20-30% kwiindleko.
Umsebenzi wokuqala womatshini udibanisa ibhloko kwaye unqumle iimpawu zokukhwela. Imingxuma yeebholiti, izikhonkwane zendawo, amangeno omzila wamanzi. Lo msebenzi wenzeka kumatshini wokungqusha oqhelekileyo. Akukho nto engcono. Emva koko ibhloko ishukuma iye kwi-CNC ukwenzela ukurhaxa kwecango. Imodeli ye-3D evela kumthengi iqhuba indlela yesixhobo. I-roughing ishiya i-0.3-0.5mm yesitokhwe kuyo yonke imiphezulu yokupasa kokugqiba. Ukuzama ukusondela ngakumbi kunomngcipheko wokuphambuka kwesixhobo kunye namanqaku okuncokola athatha ngonaphakade ukupholishwa kamva.
Ukugqitywa komatshini kuzisa imilinganiselo yomngxunya kwinkcazo yokugqibela. Ukunyamezela kuqhuba ± 0.02mm kwiimpawu ezibalulekileyo ezifana nepokotho ye-eriyali kunye nemigangatho yomgca wokwahlukana. Umgangatho wepokotho kufuneka ube mcaba ngaphakathi kwe-0.01mm okanye i-RFID inlay rocks xa uhleli. Izingqusho zebhola kwi-1mm kunye ne-2mm yedayamitha zibamba imiphezulu egobileyo. I-radii encinci iya kwi-EDM.
Ukusika i-Electrode kuqhuba ngokunxuseneyo nomatshini wokugaya umngxunya. Igraphite okanye ubhedu kuxhomekeke ekubeni yintoni ukugqiba okufunwa ngumgodi. Oomatshini begraphite ngokukhawuleza kwaye babambe iinkcukacha ezintle. I-Copper ivelisa umgangatho ongcono kwintsimbi kodwa iguga ngokukhawuleza kwaye ixabisa ngaphezulu kwe-electrode nganye. Uninzi lweefob zokubumba zisebenzisa i-electrode yegraphite kunye nenyathelo lesibini lokupholisha emva koko.
Isikhululo se-EDM sitshisa oko i-CNC ayikwazi ukufikelela kuyo. Iikona zangaphakathi ezibukhali. Iindawo zokubeka ezinzulu ezimxinwa. Iinkcukacha zelogo ngeendonga ezithe nkqo. I-electrode ingena kwi-workpiece ngelixa ukukhutshwa kombane kuphazamisa izinto. Ixesha lokutshisa lixhomekeke kubunzulu kunye nommandla wendawo. I-logo recess eyi-0.5mm ubunzulu inokuthatha iiyure ezi-4. Lo matshini ubaleka ungajongwanga ngobusuku ngenxa yeempawu ezinzulu.
Ukupholisha kwahlula ukungunda okusebenzayo kokulungileyo. I-EDM ishiya i-recast layer kwiindawo zentsimbi. Lo maleko uqinile kwaye uyaphuka. Ukupholisha kuyayisusa kwaye kuzise umphezulu kwisiphelo esichaziweyo. Imigangatho yeSPI inika wonke umntu ireferensi efanayo. I-A-1 kukugqiba kwesipili. I-B-1 iyipolishi ecocekileyo enemigca ethile ebonakalayo. I-C-1 ibonisa iimpawu ezikhanyayo zokuxutywa ngamatye. Amaqokobhe e-keyfob adla ngokucacisa i-B-2 okanye i-B-3. Iglosi ephezulu ithetha ixesha elingakumbi lokupolisha kunye nokunxiba ngokukhawuleza ngexesha lemveliso.
Ukusetyenziswa kwe-texture kwenzeka emva kokupholisha ukuba umthengi ufuna i-matte okanye i-pattered surfaces. Ukufakwa kweekhemikhali kusebenzisa iasidi ukutya intsimbi ngendlela elawulwayo. Umngundo uyagqunywa, emva koko uditshwe. Ubunzulu be-Etch buqhuba i-0.02-0.05mm yokwakheka okuqhelekileyo. I-Laser texturing ifumana umhlaba kwiipateni ezinzima kodwa ixabisa ngaphezulu kwisentimitha yesikwere.
Ukupholisa itshaneli yokomba kwenzeka kwangoko kwinkqubo ngelixa ibhloko iselula ukuyiphatha. Imipu ibhoboze imingxuma ethe tye ngentsimbi. Ububanzi buqhele ukuba yi-8-12mm. Izithuba kunye nobunzulu buxhomekeke apho ubushushu bugxila khona ngexesha lokubumba. Iitshaneli ziyaqhaga kwaye uxinzelelo luvavanywe phambi kokudibanisa ukujonga ukuvuza. Umzila wamanzi ovuzayo ngaphakathi komngundo obalekayo udala umhlwa kunye nongcoliseko olonakalisa iindawo kangangeentsuku ngaphambi kokuba nabani na alandele ingxaki.
INdibano izisa kunye ibhloko yecavity, ibhloko engundoqo, iipleyiti ze-ejector, izikhonkwane zesikhokelo, kunye nehardware yokunyuswa. Iziseko zokubumba ezisemgangathweni ezivela kwi-DME okanye i-HASCO zigcina ixesha. Umngxuma kunye nombindi wehla kwiipokotho{2}}ezazisele zenziwe. Ukulungelelaniswa kuxhomekeke kwizikhonkwane zesikhokelo kunye ne-bushings. Ukunxiba kula macandelo kubonisa njengokukhanya kumalungu ngenxa yokuba iihafu zokungunda azisadibani ngokucocekileyo.
Ukuhlolwa kwenqaku lokuqala kwenzeka kwiCMM. Oomatshini bokulinganisa abalungelelanisiweyo baphonononga imilinganiselo ebalulekileyo ngokuchasene nemodeli ye-3D. Naluphi na uphawu lwangaphandle lonyamezelo luyaphawulwa. Abarhanelwa abaqhelekileyo ziipokethi ezinzulu eziye zaphambuka ngexesha lomatshini kunye neendonga ezincinci ezihamba ngexesha le-EDM. Ukulungiswa kuthetha ukubuyela kwisikhululo se-CNC okanye se-EDM. Ngamanye amaxesha ulungiso lukhawuleza ngokugudiswa kwesandla okanye ukuwelda amabala kunye{6}}nokuphinda kwenziwe.
Uvavanyo oluqhutywayo luvelisa iinxalenye zesampulu zokwamkelwa kwabathengi. Iinqanawa zokungunda ukuya kwindawo yokubumba, ifakwe kumatshini wokushicilela, kwaye iqhube amakhulu ambalwa okudubula. Iisampulu ziya kwi-QC yokutshekishwa komgangatho kunye novavanyo lweRF. Uhlengahlengiso lwenzeka kwisiza. Ubungakanani besango bunokufuna ukuvulwa ukuba iindawo zibonisa iimpawu zokuthandabuza. Ixesha lokupholisa lisenokufuna ukwandiswa ukuba iinxalenye ziyajika emva kokuphuma. Olu hlengahlengiso luthatha usuku okanye ezimbini. Nje ukuba iisampulu zidlule, ukungunda kungene kwimveliso.
Ubalo lokudutyulwa luqala ku-zero ngelo xesha. Amaxesha okulungisa acwangciswa ngokusekwe kwimpahla elindelekileyo. Ukungunda kuya kubuyela kwigumbi lesixhobo ekugqibeleni ukuze kuhlaziywe. Imiphezulu yelayini eyahlulayo ifumana kwakhona{3}} umhlaba. Izikhonkwane ze-ejector ezigugileyo ziyatshintshwa. Ukugudiswa kuzisa ukugqiba komngxuma kukubuyisela kwinkcazo yokuqala. I-keyfob engundo{7} egcinwe kakuhle iqhuba ama-300,000 ukuya kuma-500,000 imijikelo phambi kokulungiswa okukhulu. Izixhobo ezingahoywanga ziyasilela kwakamsinyane.
