Khetho ea Alloy Ke Mokhanni oa Litšenyehelo oa # 1-E seng Geometry
Baenjiniere ba bangata ba nahana hore libopeho tse rarahaneng li phahamisa litšenyehelo tsa ho etsa matsete ka kg boholo. E fosahetse. Alloy e laola. Mona ke seo re se bonang letsatsi le letsatsi:
- Cobalt-nickel alloys (AMS 5387, T800) karolelano ea $32–$47/kg - e tsamaisoa ke ho feto-fetoha ha lintho tse tala, taolo e tiileng ea ho qhibiliha, le kalafo ea mocheso ka mor'a ho lahlela ho tsitsisa mekhahlelo ea mantlha ea gamma.
- Litšepe tse sa hloekang (CF8M, CF3M) li lula ho $18–$26/kg - li phahame ho feta tšepe ea carbon ka lebaka la chromium/nickel content le lifensetere tse thata tsa k'hemistri.
- Ductile iron (ASTM A) e tšoarella ho $9.50–$13.50/kg - ntlha e tlase ea ho qhibiliha, ho honyela ho fokolang, sistimi e tšoarelang ea likhetla.
Re kile ra qotsa ntlo ea pompo ea hydraulic ho T800 cobalt alloy ka $41.20/kg. Joometry e tšoanang ho ASTM A351 CF8M e theohetse ho $22.60/kg. Ha ho phetoho ea moralo. Metallurgy feela. Haeba tlhahiso ea hau e u lumella ho nka sebaka sa thepa - leha ho na le likhohlano tse nyane - u fumana matla litsenyehelo tsa ho lahlela matsete ka feme ea kg litheko.
Litaba tse Ratang—Empa Feela ka mor'a hore litekanyo tse mahlonoko li notletsoe
“Ho rarahana” ha ho bolele “ho bitsa chelete e ngata”—ntle le haeba ho qobella mosebetsi oa matsoho. Ts'ebetso ea matsete e ipabola ho libopeho tsa manyolo, liphasejeng tse ka hare le mabota a masesaane. Se eketsang litšenyehelo ha se kobeha kapa contour-ke likarolo tse senyang othomathike: li-undercuts tse hlokang ho kopanya boka ba letsoho, masoba a foufetseng a tebileng ho feta bophara ba 8×, kapa bokaholimo bo botle ho feta Ra 1.6 µm ntle le machining.
Taelong e 'ngoe ea morao-rao bakeng sa matlo a lisilindara tsa pompo ea piston, moreki o hlalositse mamello ea ± 0.05 mm lebota ho pholletsa le ID ea 220 mm.

Empa ha ba phutholohile mamello ho ± 0.10 mm libakeng tse sa tiisetsoeng, litšenyehelo li ile tsa theoha $ 2.30 / kg ka phello ea ts'ebetso ea zero. Molao oa rona: hlalosa lintlha tsa bohlokoa pele. Ebe u lumella casting ho tšoara tse ling kaofela.
Molumo o Fetola Ntho e 'Ngoe le E 'ngoe-Haholo-holo ka tlase ho likotoana tse 500
Litsenyehelo tsa ho lahla lichelete ka lik'hilograma tsa fektheri li theoha haholo pakeng tsa likotoana tse 1-50 le likotoana tse 500-2,000-empa lipula ka mor'a moo. Hobaneng? Tooling amortization. Lisebelisoa tsa boka ba boka bakeng sa karolo e rarahaneng e mahareng li etsa $2,800–$4,500. Ho li-pcs tse 50, ke $56- $90 e ekelitsoeng yuniti ka 'ngoe. Ho li-pcs tse 1,000? Feela $2.80–$4.50.
Re latela sena hantle. Bakeng sa 'mele oa valavu ea khatello ea tšepe e sa hloekang (1.8kg/unit), litjeho tsa rona tsa matsete tse qotsitsoeng ka feme e 'ngoe e ne e le:
