Umugqa Wokukhiqiza Isikhunta
Amabhulokhi ensimbi afika njengamabhilidi angama-rectangular. Ibanga le-P20 lamavolumu okukhiqiza ajwayelekile. Isitifiketi esibalulekile sibonisa ubulukhuni obungaba ngu-28-32 HRC{7}}owenziwe lukhuni kusukela emshinini wokugaywa. Akukho ukwelashwa okushisa okudingekayo ngaphambi komshini. Ngamathuluzi evolumu ephezulu okulindeleke ukuthi asebenze imijikelezo engu-500,000 edlule, isitolo sishintshela ku-H13 noma i-S136 engenasici. Lezi zidinga ukuqina ngemva komshini onzima, owengeza isonto kushejuli kanye no-20-30% ezindlekweni.
Umsebenzi wokuqala wokwenza izikwele ukhuphukela phezulu kwebhulokhi futhi unqamule izici ezifakwayo. Izimbobo ze-bolt, izikhonkwane zendawo, okufakiwe komzila wamanzi. Lo msebenzi wenziwa emshinini wokugaya ojwayelekile. Akukho okukhethekile. Ibhulokhi ibe isithuthela ku-CNC ukuze i-cavity roughing. Imodeli ye-3D evela kukhasimende ishayela indlela yamathuluzi. I-roughing ishiya isitokwe esingu-0.3-0.5mm kuzo zonke izindawo zokuqeda amaphasi. Ukuzama ukusondelana kakhulu kunalokho kubeka engcupheni ukuchezuka kwethuluzi kanye nezimpawu zokuxoxa ezithatha unomphela ukupholishwa ngokuhamba kwesikhathi.
Ukuqeda ukwenza imishini kuletha ubukhulu bomgodi ekucacisweni kokugcina. Ukubekezelela kusebenza ±0.02mm ezicini ezibalulekile njengephakethe lezinti kanye nezindawo zomugqa wokuhlukanisa. I-pocket floor kufanele ibe isicaba ngaphakathi kuka-0.01mm noma i-RFID inlay rocks uma uhlezi. Izigayo zokuphela kwebhola ngobubanzi obungu-1mm no-2mm zibamba izindawo ezigobile. I-radii encane iya ku-EDM.
Ukusika kwe-Electrode kuhambisana nokucushwa kwe-cavity. I-graphite noma ithusi kuye ngokuthi yikuphi ukuqeda okudingayo. Imishini ye-graphite ngokushesha futhi ibamba imininingwane emihle. I-Copper ikhiqiza isiphetho esingcono esingaphezulu ensimbi kodwa iguga ngokushesha futhi ibiza ngaphezulu nge-electrode ngayinye. Izibunjwa eziningi ze-keyfob zisebenzisa ama-electrode egraphite ngesinyathelo sesibili sokupholisha ngemuva kwalokho.
Isiteshi se-EDM sishisa lokho i-CNC engakwazi ukufinyelela kuyo. Amakhona angaphakathi acijile. Izikhala emincane ezijulile. Imininingwane yelogo enezindonga eziqondile. I-electrode ishona ku-workpiece ngenkathi ukukhishwa kukagesi kuguguleka impahla. Isikhathi sokushiswa sincike ekujuleni nendawo engaphezulu. Ukuhlehla kwelogo okungu-0.5mm ukujula kungase kuthathe amahora angu-4. Umshini usebenza ungagadiwe ngobusuku obubodwa ngezici ezijulile.
Ukupholishwa kwehlukanisa isikhunta esisebenzayo kokuhle. I-EDM ishiya isendlalelo sokuphindaphinda ezindaweni zensimbi. Lesi sendlalelo siqinile futhi siyashwabana. Ukupholisha kuyayisusa futhi kulethe ingaphezulu ekugcineni elicacisiwe. Izindinganiso ze-SPI zinikeza wonke umuntu inkomba efanayo. I-A-1 isiphetho sesibuko. I-B-1 iyipholishi enhle enemigqa ethile ebonakalayo. I-C-1 ikhombisa izimpawu zokukhandwa ngamatshe ezilula. Amagobolondo e-Keyfob ngokuvamile acacisa i-B-2 noma i-B-3. Isicwebezelisi esiphezulu sisho isikhathi esiningi sokupholisha kanye nokugqoka okusheshayo ngesikhathi sokukhiqiza.
Ukufakwa kwe-texture kwenzeka ngemva kokupholishwa uma ikhasimende lifuna izindawo ezimatte noma ezinephethini. Ukufakwa kwamakhemikhali kusebenzisa i-asidi ukuze kudle insimbi ngephethini elawulwayo. Isikhunta siyafihlwa, bese sicwiliswa. Ukujula kwe-Etch kugijima ku-0.02-0.05mm kokuthungwa okujwayelekile. I-Laser texturing ithola indawo yamaphethini ayinkimbinkimbi kodwa ibiza kakhulu ngesentimitha yesikwele.
Ukumba ishaneli okupholisa kwenzeka ekuqaleni kwenqubo ngenkathi ibhulokhi kuselula ukuyiphatha. Izimbobo zezibhamu zabhoboza izimbobo eziqondile ngensimbi. Ububanzi ngokuvamile 8-12mm. Isikhala nokujula kuncike ekutheni ukushisa kugxila kuphi ngesikhathi sokubumba. Amashaneli ayaxhunywa futhi ingcindezi ihlolwe ngaphambi kokuhlanganiswa ukuze kuhlolwe ukuvuza. Umzila wamanzi ovuzayo ngaphakathi kwesikhunta esigijimayo udala ukugqwala nokungcola okuchitha izingxenye izinsuku ngaphambi kokuba noma ubani alandele umkhondo wenkinga.
Ukuhlanganisa kuhlanganisa i-cavity block, i-core block, amapuleti e-ejector, amaphini omhlahlandlela, nezingxenyekazi zekhompuyutha ezikhwezwayo. Izisekelo zesikhunta ezijwayelekile ezivela ku-DME noma i-HASCO zonga isikhathi. Imbobo kanye nomgogodla kuwela-emaphaketheni enziwe ngomshini. Ukuqondanisa kuncike kwizikhonkwane zomhlahlandlela kanye nezihlahla. I-Wear kulezi zingxenye ibonakala njenge-flash ezingxenyeni ngoba uhhafu wesikhunta awusahlangani ngokuhlanzekile.
Ukuhlolwa kwesihloko sokuqala kwenzeka ku-CMM. Imishini yokulinganisa yokuhlanganisa iphenya izilinganiso ezibucayi uma iqhathaniswa nemodeli ye-3D. Noma yisiphi isici sokubekezelela ngaphandle siyamakwa. Abasolwa abavamile bangamaphakethe ajulile ahlubuka ngesikhathi somshini kanye nezindonga ezincane ezihamba ngesikhathi se-EDM. Ukulungiswa kusho ukubuyela emuva esiteshini se-CNC noma se-EDM. Kwesinye isikhathi ukulungisa kuyashesha ngokupholisha ngesandla noma ukushisela amabala kanye{6}}nokukhanda kabusha.
Ukugijima kwesilingo kukhiqiza izingxenye zesampula ukuze kugunyazwe ikhasimende. Isikhunta siya endaweni yokubumba, sifakwe emshinini wokunyathelisa, bese sidubula amashothi angamakhulu ambalwa. Amasampula aya ku-QC ukuze ahlolwe ubukhulu nokuhlolwa kwe-RF. Ukulungiswa kwenzeka esizeni. Usayizi wesango ungase udinge ukuvuleka uma izingxenye zibonisa izimpawu zokungabaza. Isikhathi sokupholisa singase sidinge ukunwetshwa uma izingxenye zisonteka ngemva kokukhishwa. Lawa ma-tweaks athatha usuku noma ezimbili. Uma amasampula esedlulile, isikhunta singena ekukhiqizeni.
Isibalo sokudutshulwa siqala ukusuka ku-zero ngaleso sikhathi. Izikhathi zokulungisa zihlelwa ngokusekelwe ekugqokeni okulindelekile. Isikhunta sizobuyela egunjini lamathuluzi ekugcineni ukuze silungiswe. Izindawo zolayini ohlukanisayo zithola-isisekelo. Izikhonkwane ze-ejector ezigugile ziyashintshwa. Ukupholisha kubuyisela isiphetho se-cavity ekucacisweni kwasekuqaleni. -Isikhunta se-keyfob esinakekelwe kahle sisebenzisa imijikelezo engu-300,000 kuya ku-500,000 ngaphambi kokulungiswa okukhulu. Amathuluzi anganakiwe ayahluleka ngokushesha.
