Iyo ba injeniyeri bagaragaje uruganda rukora neza mubyangombwa byamasoko, ntabwo batumiza ibyuma gusa-barasaba gusubiramo ibipimo biri munsi ya 0,02 mm, guhuza microstructure guhuza ibice bitunganijwe nubushyuhe, hamwe no kwizerwa kumikorere nyuma yamasaha 10,000 mumashanyarazi ya hydraulic valve cyangwa amazu ya pompe yo hanze. Twabonye imishinga myinshi ihagaze kuko utanga isoko yafashe cobalt-nikel alloy casting nk "akandi kazi kicyuma." Ntabwo aribyo.
Impamvu Imyitwarire Yumubiri Igena Igishushanyo mbonera-Ntabwo ari Ubundi buryo
Amavuta ashingiye kuri Cobalt nka AMS 5387 cyangwa T800 ntabwo akora imashini nkicyuma. Igipimo cyo gukomera kwakazi kiyongera nyuma ya 0.1 mm yuburebure. Ubushyuhe bwumuriro ni kimwe cya kabiri cya 304 kitagira umwanda - bityo ubuzima bwibikoresho bugabanuka 60% mugihe umuvuduko ukonje uguye munsi ya 70 bar. Mu iduka ryacu, ntabwo duhera kuri gahunda za CNC. Dutangirana nimpapuro zamakuru: ingano yubunini bwakwirakwijwe munganda, amakarita yimvura ya karbide nyuma yumuti wa annealing, hamwe nu murongo ucuramye mubyumba byombi na 400 ° C. Gusa noneho turafunga umuvuduko wa spindle, kugaburira iryinyo, hamwe nintambwe.
Iyi disipuline itandukanya ubushobozi nyabwo bwo gutoranya nubuso-urwego rwo hejuru. Pompe imwe yo muri Amerika ya ruguru OEM yatwoherereje igishushanyo mbonera cya pisitori ya pisitori ya pisitori - GD&T ifatanye cyane (Ø0.015 mm), hejuru yikimenyetso cya Ra 0.4 µm, hamwe n’ibisabwa 38-42 HRC nyuma yo gusaza. Abacuruzi babo babanje gukoresha umucanga rusange + kurangiza gutunganya. Igisubizo? Igipimo cya 37% cyibisigisigi bitewe nubutaka bwubutaka hafi yumuvuduko mwinshi. Twahinduye gushora imari hamwe no gusuka gufashwa na vacuum, twongera ibizamini bya ultrasonic mbere yo kuyikora, hamwe no kugabanya imihangayiko hagati yo kugabanuka gukabije no kurangiza. Umusaruro wasimbutse kugera kuri 94%. Igice cyatsinze hydrostatike ikizamini cya 1.5 × umuvuduko wapimwe - nta kumeneka, nta kugoreka.
Ibyiciro bine byibicuruzwa-Buri cyubatswe kunanirwa-gihamye
Twibanze gusa kubice aho gutsindwa bitwara ingaruka zakazi cyangwa umutekano. Nta gushushanya. Nta buke buke bwo kwihanganira. Gusa icyuma gikomeye-ubutumwa:
- CNC ibice.
- Ibikoresho bya Cobalt-nikel.
- Ibyuma: ASTM A48 Class 35 gray iron pump foundations—designed for vibration damping, not just static load
- Ibyuma & ibyuma bidafite ingese: Amazu ya AISI 4140 na 17-4PH kububiko bwimodoka ya winch center shaft rollers, ubushyuhe buvurwa kugirango buhuze ubuzima bwa torsional umunaniro ubuzima
Ikintu cyose cyoherejwe na raporo yikizamini cyibikoresho (MTR), raporo yubugenzuzi bwashyizweho umukono na CMM wemejwe na CMM, hamwe nigiti cyerekana inenge cyanditseho ISO 13919-1 cyo kwemererwa gusudira - kabone niyo haba nta gusudira bibaye. Kubera iki? Kuberako abakiriya batubwira abagenzuzi babo ubu barabisaba kubatanze peteroli ya Tier 1.
Ubwiza ntibugenzurwa-Bwakozwe muri, Intambwe ku yindi
Inganda zimwe zikora ubugenzuzi bwa nyuma kubice byarangiye. Turagenzura kuri bariyeri eshanu zidashobora kuganirwaho:
- Kugenzura ibikoresho bibisi: Isesengura rya Spectrometric + ibizamini bya ultrasonic kuri buri coil / bilet mbere yo gukata
- As-cast geometrie: Optical kontour scanner igenzura inguni nimpinduka yibanze mbere yo kuvura ubushyuhe
- Nyuma yubushyuhe-buvura ikarita yerekana ikarita: 9-point ya Rockwell C grid kuri zone zikomeye, ntabwo ari ahantu hamwe gusa
- Mubikorwa CMM: Nyuma yo gukomera, mbere yo kurangiza, kwemeza amafaranga yimigabane akomeza kuba umwe
- Kwemeza imikorere: Umuvuduko wumuvuduko wageragejwe kuri 1.3 pressure igitutu cyakazi; winch shafts izunguruka kuri G2.5 kuri ISO 1940-1
Tugumana inyandiko za digitale kumyaka 10 - ntabwo kuberako amabwiriza abisaba, ariko kuberako umukiriya yigeze gukurikirana ikibazo cyo kunanirwa kumurima mugice kimwe cya 2019 cobalt. Sisitemu yacu yo gukurikirana ireke kwigunga no gusimbuza ibice 147 gusa - ntabwo 5.000.
Kwizerwa bitangirana nuburyo uvuga - Mbere yuko Chip Yambere Iguruka
Umushoferi munini wigiciro muri casting neza ntabwo ari ibikoresho cyangwa umurimo. Nibikorwa byatewe nibiteganijwe nabi. Twashizemo isubiramo ryubwubatsi mugice cya cote - ntabwo ari ikinyabupfura, ahubwo ni irembo rikomeye. Iyo umukiriya atanze igishushanyo cyumubiri udasanzwe usanzwe wa valve, itsinda ryacu ryerekana ibintu bitatu mumasaha 48:
- Ihamagarwa rya GD&T rivuguruzanya no gutoranya ibisabwa (urugero, kwerekana 0 ° umushinga ku rukuta ruhagaritse rwa mm 300)
- Ubuso burangiza bidashoboka kugerwaho hatabayeho gusya kabiri (Ra 0.8 µm hejuru yumusenyi bisaba + $ 12 / kg)
- Ibikoresho byerekana kwirengagiza kwaguka k'ubushyuhe-nko guhuza intebe ya cobalt alloy valve hamwe numubiri wibyuma bya karubone muri serivisi ya parike ya cyclic
Ntabwo tuvuga "yego" kuri buri cyifuzo. Turavuga tuti "dore icyakora, dore impamvu, kandi dore ingaruka zigiciro cya buri nzira." Ukwo gukorera mu mucyo kugabanya igihe cya NRE ku kigereranyo cya 40% ugereranije - kandi byubaka ikizere vuba kurusha ikirango cyemeza.
Kubashakashatsi uruganda rukora neza abafatanyabikorwa, kwiringirwa ntabwo ari isoko ryo kwamamaza. Irapimwa: igipimo cya 0.8% cya PPM ku bikoresho bya cobalt, amasaha 72 yo kuyobora amasaha yo gukina prototype, hamwe no gutinda kwa zeru muri OEM yo mu Burayi mu 2023. Ni uguhitamo uwaguhaye isoko ufata igishushanyo cyawe atari uburyo bwo gutumiza-ahubwo ni icyemezo cyo gusangira ubwubatsi. Nuburyo ibice byingenzi byingenzi byinjiza umwanya muri sisitemu aho igihe cyo guta kigura $ 28,000 / saha.
