TL;DR —Abakhiqizi be-elekthronikhi baseJapan aba-oda imichilo yensimbi engagqwali egoqwe ngokubandayo evela eShayina ye-spring clip kanye ne-connector terminal stamping baphoqelela ukuhlolwa okunezilinganiso ezinhlanu kanye nokwensimbi okudlula ubuncane obujwayelekile be-ASTM A240 noma i-JIS G 4305. Ukwenqatshwa kwebhetshi okuvame kakhulu engikubona emaqenjini e-Japanese QA esigabeni sokuhlola esizayo ukuqina kokuqina — i-strip engu-1/4H echazwe ku-HV 250–310 akumele ibe nobubanzi obungaphezu kuka-±15 HV kulo lonke ubude bekhoyili (ukusabalala kwe-HV 60 okujwayelekile kubhekwa njengokubanzi kakhulu kwe-terminal contact spring edinga amandla okuphinda alayishwe kusengaphambili angu-±5%). Ubulukhuni bendawo kumele bube ngaphansi kuka-Ra 0.5 μm ohlangothini lokuxhumana lwe-terminal strip, futhi ukubekezelelana kobukhulu kumele kugcinwe ku-±0.03 mm nge-nominal gauge engu-0.3 mm — ukuhlukahluka kobukhulu be-strip obungu-0.05 mm kuveza ukuhlukahluka okungu-0.3 mm ekuphakameni kwamahhala kwe-spring clip eyakhiwe, okushintsha ingcindezi yokuxhumana ngo-1.2–1.5 N kusuka enanini elicacisiwe. Lesi sihloko sihlanganisa amapharamitha amahlanu okuhlola abalulekile lapho i-OEM yama-elekthronikhi yaseJapan ibeka i-oda eliphindaphindwayo le-strip yensimbi engagqwali egoqwe ngokubandayo.

Imboni yokukhiqiza yezixhumi nezindawo zokugcina ugesi eJapan — izinkampani ezifana ne-JAE (Japan Aviation Electronics), i-Hirose Electric, kanye nesigaba se-elekthronikhi sikaYazaki — isebenzisa izinkulungwane zamathani zomucu wensimbi engagqwali ogoqwe ngokucophelela ngonyaka wezingxenye ezigxiviziwe: iziqeshana zasentwasahlobo ezigcina ingxenye yesixhumi esihlanganayo (ngokuvamile ubukhulu obungu-0.2–0.4 mm, i-temperament engu-1/2H, ibanga elingu-301 noma elingu-304), kanye nezitheminali zesignali noma zamandla ezingu-0.15–0.30 mm ubukhulu ku-temperament engu-1/4H. Umucu ungena kumshini wokucindezela izitemina ku-50–200 m/min, ukhiqiza izitheminali ezingu-50,000–200,000 ngehora nge-progressive die enezidingo zokubekezelelana ezilinganiswa ngama-micrometer. Umucu ohluleka ukuhlolwa okungenayo efektri ye-elekthronikhi yaseJapan ubuyiselwa kumhlinzeki ngezindleko zomhlinzeki, kanye nesicelo sesikhathi sokungasebenzi komugqa wokukhiqiza esingu-¥200,000–¥500,000 ngehora somshini wokucindezela ongasebenzi. Sihlinzeka ngentambo yensimbi engagqwali egoqekile ebandayo kule makethe, futhi lesi sihloko sihlanganisa ukuhlolwa okuhlanu okwenziwa unjiniyela we-QA waseJapan kuyo yonke ikhoyili engenayo. Ukuze uthole uhla lwethu lokukhiqiza i-cold rolling, bheka i-ikhasi lomkhiqizo wensimbi engagqwali egoqwe ngokubandayoUkuze uthole ikhono lenqubo ekukhiqizeni imicu enembile, vakashela i-isigaba somugqa wensimbi engagqwali ngokunemba.

Ukuqina Okungaguquguquki — Kungani ±15 HV Kubalulekile Entwasahlobo Yokuxhumana

Abakhiqizi be-elekthronikhi baseJapan bachaza izinga lokushisa lomugqa wensimbi engagqwali ogoqwe ngokubandayo ngokwezindinganiso ezimbili ezisebenza ngokufana: i-JIS G 4313 (imicu yensimbi engagqwali egoqwe ngokubandayo yezipilingi) kanye nencazelo ye-ASTM A240/A480 yezimpawu zokushisa ezifanayo. Ngomugqa we-1/4H kunsimbi engagqwali engu-304, ububanzi bokuqina nge-JIS G 4313 buyi-HV 250–310 (ukusabalala kwamaphuzu angu-60). Ngomugqa we-1/2H kunsimbi engagqwali engu-301, ububanzi buyi-HV 310–370 (namaphuzu angu-60). Indinganiso iyi-ububanzi bokuqina bokukhiqizwa kwesigayo— ihlanganisa ukushintshashintsha kwenqubo evamile yokushisa kwesithando somlilo esinamathelayo (±10°C ngaphesheya kobubanzi bestrip esithandweni somlilo esinamathelayo esiqhubekayo) kanye nokushintshashintsha kokunciphisa okubandayo (±2% ekudluleni kokugcina emshinini we-Sendzimir). Kodwa kumkhiqizi wesiphetho saseJapan, ukusabalala kobunzima obungamaphuzu angu-60 kubanzi kakhulu kusiphetho okumele sinikeze amandla okuxhumana ahambisanayo phakathi kwezitembu ezingu-500,000.

Amandla okuxhumana e-spring clip terminal alingana namandla okukhiqiza e-strip ku-radius egobile eyakhiwe. Ku-1/2H 301 stainless steel clip engu-0.3 mm ubukhulu obugobile ku-radius yangaphakathi engu-0.3 mm (isilinganiso se-R/t = 1.0 - ukugoba okuqinile kokuxhumana kwe-spring), i-engeli ye-springback ishintsha ngo-0.5° kukho konke ukwanda kwe-10 HV kobunzima be-strip. Ukwehluka kwe-60 HV ku-coil kusho ukuthi i-engeli ye-springback ihluka ngo-3° - ukuphakama okungena-clip okwenziwe kuyahluka ngo-0.2 mm esicongweni sokuxhumana, futhi amandla okuhlangana ashintsha kusuka ku-8 N ecacisiwe kuya phakathi kuka-6.5 N no-9.5 N. Ikhasimende laseJapan lenqaba noma yiliphi i-batch lapho ubunzima buhluka khona ngaphezu kuka-±15 HV ku-coil (ifasitela elinamaphoyinti angu-30). Sihlangabezana nale mfuneko ngokusebenzisa umshini wokugoqa ngokunciphisa okulawulwayo ngokudlula kanye nokulinganisa ubunzima ezindaweni ezinhlanu (unqenqema lwesobunxele, ikota yesobunxele, isikhungo, ikota yesokudla, unqenqema lwesokudla) ku-coil ngayinye ku-batch, siqopha ukuphambuka okujwayelekile. Uma ukuphambuka okujwayelekile kudlula i-8 HV, ikhoyili yehliselwa kuhlelo lokusebenza olungaqondile. Uhla lomkhiqizo we-strip egoqekile ebandayo luboniswa ku-ikhasi lomugqa ogoqwe ngokubandayo.

Ubulukhuni Bomphezulu — Ra 0.5 μm Yokuzinza Kokumelana Nokuxhumana

Ubulukhuni bomphezulu womugqa ogoqwe ngokubandayo ohlangothini lokuxhumana lwe-terminal bunquma indawo yokuxhumana yangempela phakathi kwe-terminal nephini lokuhlangana. I-terminal ephethe u-3 A wamanje wesiginali enokumelana kokuxhumana okungu-20 mΩ idinga indawo yokuxhumana yangempela okungenani engu-0.01 mm² ngamandla okuxhumana ajwayelekile (8 N). Uma ubulukhuni bomphezulu womugqa bungu-Ra 1.0 μm esikhundleni sika-Ra 0.5 μm, ama-asperities (iziqongo) ebusweni aphakeme ngo-0.5 μm - ukuguquguquka kwepulasitiki kwala ma-asperities ngaphansi kwamandla okuxhumana kudala indawo yokuxhumana yangempela encane ngo-30-40%, okusunduza ukumelana kokuxhumana kusuka ku-20 mΩ kuya ku-30-35 mΩ. Ku-3 A, ukuhlakazeka kwamandla endaweni yokuxhumana (I²R = 9 × 0.035 = 0.315 W) endlini yokuxhuma evalekile ngaphandle komoya kudala ukuphakama kwezinga lokushisa lendawo elingu-15-25°C ngaphezu kwe-ambient. Ku-harness ye-engine bay harness yezimoto ezingama-60, ukushisa okuhlanganisiwe kwehlisa izinga lokushisa kwentwasahlobo yesiteshi — ukucindezeleka kwensimbi engagqwali okungu-1/2H kuphumula ngo-10–15% ku-100°C emahoreni angu-3,000, kunciphisa amandla okuxhumana futhi kwandise ukumelana kokuxhumana ngomjikelezo wokuhluleka okuqinisayo.

Ubulukhuni bomphezulu westrip buncike ezintweni ezine: ukuqeda kobuso bomphetho womsebenzi (ukuqeda komhlaba u-Ra 0.1 μm ukuze kudlule okokugcina), ukuhlanzeka kwamafutha okugoqa (uhlelo lokuhlunga oluyi-5 μm oluvimbela izinhlayiya eziqinile ukuthi zingangeni ebusweni bomphetho), ukucindezeleka komphetho ngesikhathi sokudlula kokugcina (okugcinwa ngaphakathi kuka-±3% wendawo ebekwe yi-torque evaliwe ye-tension reel), kanye nomoya we-annealing furnace (umkhathi wokunciphisa i-hydrogen-nitrogen ku-1,050°C kuma-grade angu-304 no-301 uvimbela imvula ye-carbide kanye ne-oxidation yomphetho). Silinganisa ubulukhuni bomphetho ezindaweni ezintathu kulo lonke ububanzi bomphetho ku-coil ngayinye sisebenzisa i-contact profilometer ngokwe-ISO 25178. I-Ra ejwayelekile ingu-0.35–0.45 μm ohlangothini olukhanyayo kanye no-0.45–0.55 μm ohlangothini olu-matte — ikhasimende likhetha uhlangothi lobuso bomphetho wokuthinta. Ukuze uthole ikhono lokukhiqiza umphetho wokunemba oqinile, bheka ku-ikhasi lomkhiqizo we-strip yensimbi engagqwali eqondile eqinile.

Ukubekezelela Ubukhulu — ±0.03 mm Ilawula Ukuphakama Okukhululekile Kwesiqeshana Esigobile

Ukubekezelela ukujiya ku-strip egoqwe ngokucophelela kuchazwe ngokwe-ASTM A480 njengo-±10% we-nominal gauge yobubanzi obufika ku-600 mm. Ku-nominal thickness engu-0.30 mm, lokhu kungu-±0.030 mm. Abakhiqizi be-elekthronikhi baseJapan nabo baphoqelela lokhu kubekezelelana, kodwa ngaphezu kwalokho balinganisa ukujiya kobubanzi ku-strip ububanzi (iphrofayili yomqhele) kanye nobude be-strip (umehluko we-gauge band). Umqhele — umehluko wobukhulu phakathi kwe-strip centre kanye nomphetho we-strip — akumele udlule u-0.010 mm ku-strip ububanzi obungu-200 mm ku-nominal gauge engu-0.30 mm. Ukuhlukahluka kwe-gauge band — ukuhlukahluka kobukhulu obuphindaphindwayo ku-length okubangelwa ukungavamile kwama-backing bearings e-Sendzimir mill — akumele udlule u-0.005 mm ku-length ubude obungamamitha ayi-10.

Kungani leli zinga lokunemba kwe-spring clip? I-spring clip egxiviziwe egoba ku-radius engu-0.5 mm enobukhulu be-strip obungu-0.30 mm (R/t = 1.67) inokuphakama okukhululekile okubunjiwe okungu-4.5 mm. Uma ubukhulu be-strip bungu-0.33 mm (umkhawulo ophezulu ongu-±0.03 mm), i-geometry ye-springback iyashintsha ngoba umzuzu we-inertia we-cross-section (I = b × t³ / 12) uyanda ngo-(0.33/0.30)³ = izikhathi ezingu-1.33 — i-spring eyakhiwe iqine ngo-33% ekugobeni, kanti ukuphakama okukhululekile kwe-slip kuyanda ngo-0.3 mm kuya ku-4.8 mm. Amandla okufaka iphini lokuhlanganisa ayashintsha kusukela ekuchazweni okungu-8 ± 1 N kuya ku-10 ± 1.5 N — ngaphezu komkhawulo ophezulu wekhasimende ongu-9 N. Umphumela ofanayo obuyela emuva uyenzeka uma ubukhulu busemkhawulweni ophansi ongu-0.27 mm. Ukubekezelelana kobukhulu obungu-±0.03 mm kuhumusha ngokuqondile ukushintshashintsha kwamandla okungu-±0.25 N kusiqeshana sentwasahlobo — futhi ifasitela lokwamukela lekhasimende lingu-±1 N. Sibamba ubukhulu obungu-±0.02 mm enkabeni yekhoyili kanye no-±0.03 mm emaphethelweni ngokusebenzisa isilawuli se-gauge esivaliwe esizenzakalelayo ku-pass yokugcina ye-Sendzimir mill. Ukuze uthole imikhiqizo ye-strip yensimbi engagqwali kabanzi, bheka ku-ikhasi lesigaba somugqa wensimbi engagqwali.

I-Edge Burr — I-Punch-and-Die Lifetime Interface

Umcu ogoqwe ngokubandayo uqhekeka kusukela ku-coil egcwele ububanzi ube yimicu emincane (20-200 mm ububanzi, kuye ngobubanzi be-terminal kanye nokuhlelwa kwe-stamping die) emgqeni wokuqhekeka onemimese ejikelezayo. Inqubo yokuqhekeka idala i-burr emphethweni osikiwe - udebe oluphakanyisiwe lwezinto ezisusiwe oluphuma ngaphezu kobuso be-strip ngo-0.02-0.15 mm kuye ngokuthi ummese ubukhali kangakanani, isikhala sokuqhekeka (igebe phakathi kwemimese ephezulu nengezansi, elibekwe ku-5-10% wobukhulu be-strip ukuze kuqhekeke ngokunembile), kanye nokucindezeleka kwe-strip ku-recoiler yokuqhekeka. Ku-die yokuqhekeka ye-terminal yaseJapan egijima ngama-stroke angu-200 ngomzuzu ngesikhala sokubhoboza-ukuze-ufe esingu-0.020 mm (7% wobukhulu be-strip obungu-0.30 mm), i-burr emphethweni we-strip engenayo yinto yokuqala ethinta indawo ye-die. Ukuphakama kwe-burr okungaphezu kuka-0.05 mm kuzobangela i-gall surface die ngaphakathi kwemivimbo engu-50,000 - i-galling idala ukuklwebheka endaweni ye-die edlulisela kuyo yonke i-terminal elandelayo, ikhiqize umugqa ophakanyisiwe ebusweni be-terminal ovimbela i-terminal ukuthi ihlale ngokuphelele endlini yokuxhuma.

Silawula ukuphakama kwe-edge burr ngokusebenzisa incazelo yokusika yamapharamitha amathathu: ukugqagqana kommese kusethwe ku-30% wobukhulu be-strip (0.09 mm ngomugqa ongu-0.30 mm), isikhala esiseceleni singama-8% wobukhulu be-strip (0.024 mm), kanti i-radius yonqenqema lommese igcinwa ingaphansi kuka-0.01 mm — imimese yokusika iyagaywa kabusha lapho i-edge radius idlula u-0.02 mm, okwenzeka ngemva kwamathani angu-30-50 okusika ngesethi yommese. Ukuphakama kwe-burr kulinganiswa ngesibonakaliso sokudayela kumitha yokuqala kanye nemitha yokugcina ye-slit coil ngayinye. Ukuphakama kwe-burr okudlula u-0.05 mm kususwa ngesiteshi sokususa ukububula (isethi yamabhulokhi e-carbide agcwele intwasahlobo adlula unqenqema lwe-burr ngo-0.03 mm ohlangothini ngalunye) ekuphumeni komugqa wokububula. Umsebenzi wokususa i-burborne ubiza u-¥0.30 ngemitha ngayinye yomugqa — kodwa ibhili lokulungisa i-die ye-progressive die yomkhiqizi wesiteshi saseJapan esineziteshi eziyisithupha ingu-¥150,000–¥300,000, kanye nesikhathi sokungasebenzi komugqa wokukhiqiza. Umsebenzi wokususa i-burborne ufakiwe njengejwayelekile kuzo zonke izi-oda ze-strip ezigoqwe ngokushisa eziqondile zamakhasimende e-electronics aseJapan, ngaphandle kwenkokhiso eyengeziwe.

Ukupakishwa Nokulethwa — Izidingo Zekhoyili Ye-JIT

Abakhiqizi beziteshi zikagesi zaseJapan basebenza ngokugeleza kwezinto ezisebenza ngesikhathi esifanele (JIT). Ikhoyili engu-500 kg yomugqa ogoqwe ngokucophelela ongu-0.30 × 100 mm onobude obumaphakathi bomugqa ongu-2,100 m iyamukelwa futhi ibekwe ngqo ku-reel yokucindezela i-multi-slide stamping press payoff — akukho sitoreji esiphakathi, akukho ukubamba kokuhlola. Ikhoyili kumele ingabi namamaki okugoqa ahambisanayo (ukugoqa okwenziwa yi-outer wrap kuma-inside wraps ngesikhathi sokugoqa nokuphatha), ngoba ukugoqa okujule ngo-0.02 mm ebusweni bomugqa kudala umthwalo we-die impact ku-stamping press — i-punch ihlangana nokumelana okwengeziwe okungu-0.02 mm kuleyo ndawo, i-press ram iyathambekela, futhi umphetho oqoshiwe we-punch tip ukhiqiza i-scrap terminal.

Imininingwane yokupakisha yamakhoyili athunyelwa eJapane ihlanganisa: i-spool yensimbi (ububanzi bangaphakathi be-mandrel bungu-300 mm, ububanzi bangaphandle bungu-450 mm, ama-flange aseceleni abungu-150 mm ububanzi), inxeba le-strip ngaphansi kokucindezeleka okuqhubekayo (50 N ngo-10 mm wobubanzi be-strip — 500 N ngomugqa obanzi ongu-100 mm), ukugoqa ngakunye kuhlukaniswe ngeshidi le-polyethylene elingu-0.10 mm ukuze kuvinjelwe ukugoqana kwe-wrap-to-wrap, i-coil ivalwe esikhwameni sokuvimbela umswakama we-vacuum esine-silica gel desiccant (insimbi engagqwali ayigqwali, kodwa iphepha le-interleaf kumele ligcinwe ngaphansi kuka-10% womswakama ohlobene ukuvimbela ama-organic acid ephepha ukuthi angangcolisi ubuso be-strip ngesikhathi sokuthutha olwandle), kanye ne-coil epakishwe ekhrethini lokhuni elinesisekelo se-foam esinciphayo. Inani lamajoyinti okushisela kukhoyili — ikhoyili ngayinye yakhiwa ngokushisela ama-strips amaningi e-master coil angu-5-tonne kusukela ekuqaleni kuya ekugcineni emgqeni wokunqamula — lilinganiselwe kujoyinti elilodwa lokushisela ngamamitha angu-500 kuma-oda aseJapan, uma kuqhathaniswa nezinga lomkhakha elingu-1 ngamamitha angu-300. Indawo yamajoyinti okushisela imakwe ngomugqa ophuzi opende ongamasentimitha angu-30 ngaphambi nangamasentimitha angu-30 ngemva kwejoyinti, futhi umqhubi we-stamping press uyalwa ukuba asike futhi alahle indawo yamajoyinti kumhlahlandlela wokungena kwabezindaba.

Uhla oluphelele lwemikhiqizo esiyinikezayo yezinhlelo zokusebenza zokunyathela ngokunemba lubhalwe ku-ikhasi lekhathalogi yomkhiqizo.

Uhlu Lokuhlola Lokwamukelwa Kwe-Japanese QA Incoming Inspection

Ukuze uthole imininingwane yamanje yokuthumela kwamanye amazwe kanye namanani omugqa wensimbi engagqwali ogoqwe ngokucophelela,ikhasi lomkhiqizo womugqa oqondile oqinilekufaka phakathi amazinga okushisa atholakalayo kanye nemikhawulo yobukhulu. Ukuze uthole ukuqonda okubanzi kokucubungula imicu yensimbi engagqwali,ikhasi lomkhiqizo eligoqwe ngokubandayoichaza imishini yokukhiqiza kanye nezinyathelo zenqubo.

Uhlelo lwe-Japanese Industrial Standards luhlinzeka ngohlaka lwezinto —Imichilo yensimbi engagqwali egoqwe ngokubandayo ye-JIS G 4313 yezipilingiiyindinganiso esebenzayo ye-tempers ye-1/4H kanye ne-1/2H esetshenziswa ekunyathelweni kwe-electronic spring contact stamping. Ukuze kubhekwe emhlabeni jikelele ngokuhlolwa kwezixhumi,Izindinganiso zokuhlola i-terminal yesixhumi se-SAE Internationalchaza indlela yokulinganisa ukumelana kokuxhumana kanye nemibandela yokuhlola yamatheminali okuxhuma asetshenziswa emishinini kagesi.

imibuzo ejwayelekile ukubuzwa
