Kodi kuyika ndalama kumawononga ndalama zingati pa kg? Funsoli limafika pa desiki iliyonse ya injiniya wogula zinthu, ma RFQ asanakhalepo, pakuwunika bajeti, makamaka poyerekezera ogulitsa akunyanja. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., talembapo ma projekiti opitilira 1,200 oponya ndalama kuyambira 2018. Tawona mawu akugwedezeka kuchokera ku $ 8.50 mpaka $ 47 / kg - osati chifukwa chamasewera owonetsa. Kusiyanaku kumachokera kuzinthu zinayi za konkriti: mtundu wa alloy, zovuta za gawo, kukula kwa batch, ndi zofunika kumaliza. Bukuli limadula phokoso. Zimakupatsirani mitengo yamtengo wafakitole-osati milingo yamalingaliro, koma zomwe zimasuntha singano pakupanga kwenikweni.
Alloy Choice Ndiye #1 Woyendetsa Mtengo-Osati Geometry
Mainjiniya ambiri amaganiza zowoneka bwino zimakweza mtengo wopangira ndalama pa kg kwambiri. Zolakwika. Aloyi amalamulira. Nazi zomwe timawona tsiku ndi tsiku:
- Cobalt-nickel alloys (AMS 5387, T800) avareji $32–$47/kg - motsogozedwa ndi kusakhazikika kwakuthupi, kuwongolera mwamphamvu kusungunula, ndi chithandizo cha kutentha kwapambuyo-kuponyedwa kuti akhazikike magawo apamwamba a gamma
- Zitsulo zosapanga dzimbiri (CF8M, CF3M) zimatera pa $18–$26/kg — zokwera kuposa zitsulo za kaboni chifukwa cha chromium/nickel zili ndi mazenera olimba a chemistry
- Chitsulo chachitsulo (ASTM A) chimakhala chokhazikika pa $9.50–$13.50/kg - malo osungunuka otsika, kuchepa pang'ono, dongosolo lokhululukira zipolopolo
Nthawi ina tidatchulapo nyumba yapampu ya hydraulic mu T800 cobalt alloy pa $41.20/kg. Ma geometry omwewo mu ASTM A351 CF8M adatsika mpaka $22.60/kg. Palibe kusintha kwapangidwe. Metallurgy basi. Ngati dzina lanu limaloleza m'malo mwazinthu - ngakhale ndizovuta zazing'ono - mumapeza mwayi mtengo wogulitsa pa kg fakitale mitengo.
Zinthu Zovuta—Koma Pokhapokha Ngati Miyeso Yovuta Yatsekedwa
“Zovuta” sizitanthauza “zodula”—kupatulapo ngati zikukakamiza kugwira ntchito yamanja. Kupanga ndalama kumapambana pamawonekedwe a organic, ndime zamkati, ndi makoma owonda. Zomwe zimawonjezera mtengo si kupindika kapena mikombero—ndizinthu zomwe zimaphwanya makina: zotchingira zomwe zimafuna kulumikiza sera ndi manja, mabowo akhungu akuya kuposa 8× diameter, kapena pamwamba amamaliza bwino kuposa Ra 1.6 µm popanda makina.
Mu dongosolo lina laposachedwa la nyumba za silinda ya pampu ya piston, kasitomala adatchula ± 0.05 mm kukula kwa khoma pa ID ya 220 mm. Izi zidayambitsa kusanthula kwathunthu kwa CMM pagawo lililonse-ndi 14% premium yopitilira ± 0.15 mm. Koma atapumula kulolerana ndi ± 0.10 mm pamalo osasindikiza, mtengo unatsika $2.30/kg ndi zero magwiridwe antchito. Lamulo lathu: tanthauzirani ma datum ovuta poyamba. Ndiye lolani kuponyera kugwire zina zonse.
Voliyumu Imasintha Chilichonse-makamaka Pansi pa Zidutswa 500
Ndalama zoponyera ndalama pa fakitale imodzi zimatsika kwambiri pakati pa zidutswa 1-50 ndi zidutswa 500-2,000-koma mapiri pambuyo pake. Chifukwa chiyani? Tooling amortization. Kuyika kwa sera pagawo lapakati lovuta kulipirira $2,800–$4,500. Pa ma PC 50, ndiye $56- $90 yowonjezeredwa pagawo lililonse. Pa ma PC 1,000? $2.80–$4.50 yokha.
Timatsata izi molondola. Pagulu la valve yamagetsi yachitsulo chosapanga dzimbiri (1.8kg/unit), mtengo wathu wotengera ndalama pafakitale iliyonse unali:
- $28.40/kg pa 50 pcs (kuphatikiza zida zonse + 3-zipolopolo iterations)
- $21.90/kg pa 500 pcs (chida chokwanira, chokongoletsedwa chowumitsa chipolopolo)
- $20.30/kg pa 2,000 pcs (kutsegula kwa ng'anjo yowongoleredwa kukhathamiritsa, kuchuluka kwa zidutswa mpaka 2.1%)
Palibe zamatsenga. Fiziki yokha, kuwongolera ndondomeko, ndi kukhazikitsidwa kobwerezabwereza.
Kumaliza Sikosankha - Ndi Mtengo Pansi Pansi, Osati Gawo
"As-cast" ndizosowa m'mafakitale. Makasitomala ambiri amafunikira kugwetsa kwamphamvu komanso kuwomberedwa. Koma gawo lililonse lowonjezera limakhala ndi mtengo wake:
- Vibratory deburr + alumina kuphulika: +$0.85/kg
- Electropolish (Ra ≤ 0.4 µm): +$4.20/kg
- Passivation (ASTM A967 Nitric): +$1.10/kg
- Kugaya kokulirapo kwa nkhope zomata: +$6.90/kg (kuyezedwa pankhope, osati gawo lililonse)
Posachedwa takonzanso dongosolo la nozzle ya cobalt pomwe kasitomala adapempha electropolish *ndi* kugaya komweko pamipando iwiri yaying'ono. Mapeto okhawo adawonjezera $ 11.30 / kg-kuposa mtengo woyambira wa kalasi ya alloy. Phunziro: tchulani zosindikizira, zithunzi, kapena okwatirana okha. Dumphani zomaliza zodzikongoletsera pokhapokha ngati kukana dzimbiri kapena kusinthasintha kwakuyenda kukufuna.
Kupeza Mitengo Yeniyeni Kumayamba Ndi Chojambula Chanu-Osati Bajeti Yanu
Mawu achidule alibe ntchito. Mtengo weniweni woyika ndalama pamtengo wamtengo wafakitale umafunikira ma callout a GD&T, ma certs (AMS, ASTM, EN), ndi zolemba zomaliza - osati "chitsulo chosapanga dzimbiri, malo abwino." Ku QINGDAO QIANGSENYUAN TECHNOLOGY, gulu lathu logwira mawu limawunikanso zojambula zilizonse kuti zitheke kupanga musanatchule. Timayika chizindikiro pachiwopsezo: kuwonongeka kwa kutentha m'mikono yayitali yopyapyala, kusweka kwa zipolopolo m'miyendo yakuthwa yamkati, kapena kutulutsa sera m'matumba akuya. Ndemanga imeneyi imatenga maola 48 ndipo imasungidwa pakadutsa milungu ingapo.
Ngati mukuyang'ana ogulitsa, funsani kuchuluka kwa zinyalala pagulu lanu la aloyi, zipolopolo zawo zimakhala nthawi, komanso ngati ali ndi labu yawo ya ceramic slurry. Zambirizi zimalosera kusasinthika kuposa pepala lililonse lamitengo. Ndipo kumbukirani: mawu otsika kwambiri nthawi zambiri amabisa ndalama zogwirira ntchitonso, kuchedwa koyang'anira, kapena kusuntha pang'ono pamagulu.
Zolondola, zotheka kuchita mtengo wogulitsa pa kg fakitale kuyerekezera—zozikidwa pa ndondomeko yeniyeni ya deta, osati maspredishiti—kuyamba ndi chojambula chovomerezeka ndi zinthu zotsimikiziridwa. Ena onse amatsatira.
