Umqobo kwimveliso yomthamo ophantsi kwiinkqubo ezininzi zokwenza izixhobo. I-die casting die ibaleka i-$30,000–100,000+ kwaye iyavakala ukuba ihlawulwe ngexabiso elikhulu. Idayisi yokukhohlisa ngokufanayo ifuna umthamo. Isixhobo sokuphosa utyalo-mali - inaliti ye-aluminiyam ye-wax iyafa - ngokuqhelekileyo ixabisa iqhezu laloo nto, rhoqo i-$ 1,500-8,000 ngokuxhomekeke kubunzima, kwaye ivelisa iipateni ngokukhawuleza.
Qhuba izibalo kwi-hypothetical 1.2 kg bracket kumaqhekeza angama-200 ngonyaka:
- I-CNC ukusuka kwipleyiti: ~ 85% yezinto eziphathekayo ziba chips; iiyure ezininzi zokusila inxalenye nganye; ixabiso leyunithi lihlala liphezulu ngonaphakade.
- Ukwenziwa kwesanti: izixhobo ezingabizi mali ininzi kodwa ± 1.5 mm+ ukunyamezela, umphezulu ombi, kunye nomatshini wesibini phantse kuwo wonke ubuso obusebenzayo.
- I-Die casting: izixhobo zodwa zodwa zingaphezulu kwenkcitho yonyaka yonke.
- Ukwenziwa kotyalo-mali: isixhobo esiphakathi, ukuchaneka kwe-CT5–6, uninzi lwayo lusebenza njenge-cast.
Kwiziqwenga ezingama-200, isixhobo sotyalo-mali sincipha ngokukhawuleza, kwaye konke ukuphosa emva koko kubiza imali engaphantsi kunomatshini olinganayo. I-crossover echasene ne-CNC-ukusuka-eqinile ngokwesiqhelo iwela phakathi kwama-20 kunye ne-100 amaqhekeza ngokuxhomekeke kwijometri-intsingiselo yeendawo ezininzi zesiko, kunye neeodolo ezincinci zokwenyani zitshiphu njengokusaswa.
Isantya sePrototype Ngaphandle kwePrototype Compromise
Iishedyuli zophuhliso lwemveliso zohlwaya amaxesha okukhokela izixhobo. Ubulumko obuqhelekileyo buthi iprototypes kufuneka zenziwe ngoomatshini kuba ayithathi sixhobo-kodwa i-3D eprintiweyo iipateni zokuphosa ziye zayichitha loo ngcinga.
Nge- QuickCast / iipateni ze-resin ezikhatywayo , ukuhamba komsebenzi wokuphosa ngoku kubonakala ngathi: imodeli ye-CAD igqitywe ngoMvulo; iipateni eziprintwe ngobusuku; oonokrwece bakhiwe, badutyulwa baza baphoswa kwisithuba seveki; iinxalenye ezinikezelwe kwi-alloy yokuphosa, kwijometri ekufutshane-yokugqibela, iintsuku eziyi-10-14 ukusuka ekukhululweni komzobo. Thelekisa oko ngokwenza inxenye ye-5-axis entsonkothileyo (enokuthi ikhawuleze kwisiqwenga esinye kodwa ingalinganisi ukuya kuma-20) okanye ilinde iiveki ezi-6 ukuya kwezili-10 ukulungiselela izixhobo eziqhelekileyo.
I-advanteji yeqhinga inobuqili kunesantya: i-prototype castings kukuphosa okwenyani. Baphethe i-microstructure ye-alloy yokwenyani, uguqulo lwecandelo lokwenyani, kunye neyona ndawo iphosayo yenkqubo yemveliso. Xa uqinisekisa uyilo kwi-investment-pattern investment castings, uqinisekisa inkqubo yemveliso ngaxeshanye - hayi uqikelelo lomatshini oluya kuziphatha ngokwahlukileyo xa luphoswe kuthotho. Uhlaziyo loyilo olufunyenwe kwinqanaba leprototype lixabisa iiyure zobunjineli; uhlaziyo olufanayo olufunyenweyo emva kokuba izixhobo zemveliso zisikiwe zibiza isixhobo esitsha.
Inkululeko yoyilo ethi imiqulu ephantsi iSebenzise
Ukwenziwa komthamo ophezulu wohlwaya ubunzima bejometri kuba ubunzima buhlala kwizixhobo ezibizayo. Ukuphosa utyalo-mali kuyayivuza, kuba "isixhobo" yipatheni ye-wax - kunye nobunzima kwipatheni phantse simahla.
Oku kubaluleke kakhulu kwivolumu ephantsi, apho iindawo zikholisa ukuba:
- Ukutshintshwa kwefa kumacandelo akusekho sitokhwe - amaxesha amaninzi ukufakwa kwezinto ezintsonkothileyo ezingazange zenzelwe ukwenziwa ngomatshini
- Ukudityaniswa kweewelds ezinamacala amaninzi zibe yintsimbi enye (isibiyeli, iigussets ezintathu, kunye neepads ezimbini ezixhonywayo ziba yinxalenye enye - ukuphelisa ukuhlolwa kwe-weld kunye namanqaku okusilela)
- Uyilo oluqhutywa yintsebenzo - iitshaneli zangaphakathi, iimbambo ezijijekileyo, iimilo ze-organic ezilungiselelwe ukuqina-to-weight ukuba akukho nkqubo yokunciphisa inokuvelisa ngokoqoqosho.
Xa ubuninzi buncinci, ukulungiswa ngokutsha kokuphosa kulula ukulungelelanisa: i-tooling ithozamile, ijometri ayithintelwanga ngama-angles ayidrafti okanye imigca yokuhlukana, kwaye enye i-casting ithatha indawo yendibano. Sihlala siguqula izinto ezilukiweyo ezidityanisiweyo zabakhi bezixhobo kwakhona zibe ziicasts enye ezinexabiso eliphantsi kwaye zomelele kuneweldment eziyibuyiselayo.
Iimfuno zoMgangatho aziphumli kwiVolumu ephantsi-Nathi asiphumli
Ukucinga rhoqo kukuba abanikezeli bevolumu ephantsi basebenza kwimigangatho yomgangatho ophantsi. Kuyo nantoni na echukumisa uxinzelelo, ukuphakamisa, okanye imithwalo ye-drivetrain, loo ngcinga iyingozi. Iibhetshi ezincinci zisafuna:
- Ukulandelwa kwemathiriyeli epheleleyo - amanani obushushu, ikhemistri, kunye neziphumo zovavanyo lomatshini (EN 10204 3.1)
- Ukuqinisekiswa komgangatho -i-CMM ijongiwe amanqaku okuqala ngokuchasene nomzobo, kunye nokujonga okusekwe kwigeyiji kuthotho
- Ukulawulwa kwesiphako - umgangatho ofanayo wegobolondo, ukuqeqeshwa okuthululwayo, kunye ne-NDE (MT / UT / RT) isetyenziswe kumyalelo we-50-piece njenge-50,000-piece one
- Uxwebhu lwenkqubo - kwiinkqubo zemoto kunye noohola bendlela, uxwebhu lwesimbo sePPAP nakwimiqulu yemveliso yebhulorho
Lo ngumgaqo wokhetho ekufuneka abathengi bawuphonononge: buza umntu oza kuba nomthamo ophantsi ofumanekayo ukuba balawula njani umgangatho kwi-odolo yeeqhekeza ezingama-30. Umboneleli okwaziyo uphendula ngeenkqubo ezifanayo abazisebenzisayo kwimveliso ye-serial - kuba iinkqubo ziyancipha, azicimi. Njengefektri eqinisekisiweyo ye-IATF 16949, siqhuba inkqubo enye yomgangatho kuyo yonke isayizi yeodolo; Isatifikethi asiyazi ukuba inkulu kangakanani ibhetshi.
Ibhetshi encinci ukuya kuthotho: Ibhulorho ngaphandle kweSikhewu
Uninzi lwabathengi bethu baqala encinci - iprototype eqhuba i-10, i-oda yebhuloho ye-200 ngelixa i-ramps yabathengisi basekhaya - kwaye ikhule ibe yimveliso ye-serial. I-advanteji yotyalo-mali apha kukuqhubekeka: ipateni efanayo yesixhobo, inkqubo yomzila, kunye nesikali sesicwangciso somgangatho ukusuka kwinqaku lokuqala ukuya kwimiqulu yonyaka kumashumi amawaka. Akukho nto ilahlwa xa umthamo unyuka; akukho tyalo mali lwesibini lwezixhobo olufunekayo; kunye nedatha yenkqubo ebanjwe kumthamo ophantsi (imbuyekezo ye-shrinkage, imveliso yokuphosa, isakhono kwimilinganiselo ebalulekileyo) ithwala ngokuthe ngqo kwimveliso yochungechunge.
Thelekisa oko kunye ne-classic trap: i-prototyping by machining, emva koko ufumanisa kwinjongo yemveliso ukuba i-designed machined ayiguquki - i-undercuts, iindonga ezibhityileyo kakhulu, amacandelo angenako ukondla - ukunyanzeliswa ngokutsha kanye xa ishedyuli iqinile. Ukuyila ukuphosa ukusuka kwiprototype yokuqala kuphelisa eliwa.
Xa iVolume ephantsi ayikuthandi uTyalo mali
Ubunjineli obunyanisekileyo buthetha ukwazi iimeko zomda. Utyalo mali yinkqubo engalunganga xa:
- Kufuneka kanye 1-3 iinxalenye zejometri elula - machining ukusuka bar okanye ipleyiti winile ngesantya
- Inxalenye inkulu kakhulu (ngaphaya kwe-100-150 kg okanye imvulophu egqithisileyo) - ukuchithwa kwesanti okanye ukuveliswa kuyathatha indawo.
- Ukunyamezela yi-IT6 / IT7 kwiindawo ezininzi - umxholo womatshini ususa inzuzo yokuphosa
- Amacandelo eludongeni awela ngaphantsi kwe ~2.5–3 mm kubukhulu becala ngokubanzi — imida yokuphosa iyasebenza
Isiseko esihle sikuxelela oku kwinqanaba locaphulo. Sibuze, kwaye uya kufumana impendulo ethe ngqo-kuquka "umatshini" xa oko kutshiphu ngokwenene kuwe.
Umgca ongezantsi
Amalungu esiqhelo anomthamo ophantsi ahlala kwindawo apho uqoqosho lwezixhobo zokusebenza, iimfuno ezichanekileyo, kunye namaxesha okukhokela ukungqubana. Ukwenziwa kotyalo-mali kusombulula loo ngquzulwano: izixhobo ezithobekileyo, ukuchaneka kwe-net-shape kwi-alloys yobunjineli bokwenyani, isantya seprototype kusetyenziswa iipateni eziprintiweyo, kunye nenkqubo yomgangatho eqala ukusuka kwi-10 ukuya kwi-100,000 ngaphandle kokutshintsha. Kubakhi ngokutsha, abakhi boomatshini, kunye nee-OEMs ezinxibelelanisa imveliso, ayisiyonkqubo yokulalanisa - yeyona ichanekileyo.
I-Ningbo Ruican yenza i-low-to mid-volume castings yokutyalomali kwi-carbon steel, i-alloy steel, insimbi engenasici, kunye ne-ductile iron, kunye ne-in-house CNC machining, i-IATF 16949 yolawulo lomgangatho oqinisekisiweyo, kunye ne-printed-pattern prototyping ekhoyo. Sithumelele umzobo wakho kunye nomthamo ojoliswe kuwo - siyakucaphula inkqubo ehambelana ngokunyanisekileyo, ngevolumu oyifunayo.
