Ibishishwa byerekana ibishishwa bitanga ibisobanuro, bisubirwamo, hamwe nubuso burangizwa ntagereranywa no guta umucanga usanzwe - cyane cyane kubintu bito bito, binini cyane nkibice bya hydraulic valve, amazu ya pompe, hamwe na shitingi. Twakoze ibicuruzwa bisaga 12,000 bikozwe mu cyuma no mu byuma mu myaka itatu ishize byonyine - ibyinshi munsi ya ± 0,15 mm kwihanganira ibipimo na Ra 3.2 µm nkubuso. Ibi ntabwo ari theoretical. Nibibaho iyo uhujije chimie ya fenolike resin, igenzurwa nubushuhe bwibisanduku, hamwe nigihe gikwiye cyo kugenzura ubugari.
Intambwe ya 1: Gutegura icyitegererezo - Icyerekezo gitangirana na Databuja
Dukoresha ibyuma bikomeye cyangwa aluminiyumu - ntabwo bigeze ibiti cyangwa ibishishwa bito-bishongeshejwe - kubumba ibishishwa. Kubera iki? Kuberako ubuzima bwikitegererezo bugenzura neza ikiguzi kuri buri gice hejuru ya 500. Ibishushanyo byacu birimo ibishushanyo mbonera (0.5 ° –1.5 °), ibishishwa bitagira uburebure burenze mm 0.8, hamwe nibintu byinjira byinjira bikuraho gukata intoki. Buri gishushanyo gikorerwa CMM kugenzura abakiriya GD&T mbere yo gukoresha bwa mbere. Abakiriya bamwe batwoherereza prototypes yacapishijwe 3D kugirango igerageze imikorere - ariko ntitwigeze tuyitandukanya. Kwiyongera k'ubushyuhe budahuye hagati ya resin yacapishijwe nicyuma gishongeshejwe bitera intambara itateganijwe mugikonoshwa.
Intambwe ya 2: Igikonoshwa - Ubushyuhe, Resin, nigihe ntago biganirwaho
Igishushanyo cyashyutswe kugeza kuri 220-250 ° C. Ubukonje bukabije? Gukiza resin ituzuye. Birashyushye cyane? Kubora imburagihe hamwe nubusembwa bwa gaze. Turayitwikiriye n'umucanga mwiza wa silika (mesh 40-100 mesh) uvanze na 2.5-5% ya termosetting ya fenolike. Igishusho gitwikiriye kizunguruka mu isanduku yajugunywe amasegonda 10-20 - birebire bihagije kugirango igishishwa cya mm 6-12 kibeho. Noneho irahindurwa kandi itetse kuri 380–420 ° C muminota 2-4. Ibyo guteka byanyuma bihuza resin byuzuye. Simbuka, hanyuma igikonjo kirasenyuka mugihe cyo guterana. Dukurikirana ubushyuhe bw'itanura buri masegonda 90 dukoresheje kalibibasi ya termocouples - ntabwo ari ugusoma ibidukikije.
Intambwe ya 3: Inteko ibumbabumbwe - Guhuza byerekana Dimensional Stabilite
Ibice bibiri-ibishishwa bifatanyirijwe hamwe nubushyuhe bukoreshwa na fenolike cyangwa bifatanye. Nta bumba, nta misumari, nta kaseti. Kudahuza na mm 0.3 byerekana ko ari flash hejuru yumutwaro utwara igitutu - nka silindiri yimyubakire ya flanges cyangwa imyanya ya valve. Kubice bitamenyerewe, dukoresha pin ya dowel hamwe na ± 0.01 mm kwihanganira imyanya. Mbere yo gusuka, buri cyuma cyateranijwe kinyura kuri optique ihuza sitasiyo. Niba ikinyuranyo hagati ya kimwe cya kabiri kirenze mm 0.1 ahantu hose, kiraseswa-ntigikorwa. Guteranya bitangiza ikosa.
Intambwe ya 4: Gusuka no Gukomera - Kugenzurwa gutemba birinda imvururu
- Ubushyuhe busukuye bufatwa muri ± 15 ° C yuburyo bwiza - urugero, 1,420–1,450 ° C kuri ASTM A126 Icyiciro B cyicyatsi cyicyatsi
- Icyuma cyinjira binyuze mumarembo yo hasi kugirango ugabanye okiside
- Guhinda umushyitsi bibaho iminota 15-25 nyuma yo gusuka - igihe cyagenwe kuri buri gice, ntabwo ari isaha
- Nta gukonja ku gahato. Kuzimya byihuse bimenagura ibishishwa kandi bitera guhangayika gusigara mumazu yoroheje
Twigeze gusuka amazu 48 ya piston pompe ya silinderi mubushyuhe bumwe. Batandatu berekanye micro-shrink mu cyambu cya valve. Impamvu? Kugabanuka kwa 7 ° C mubushyuhe bwa salle mugihe cya 12 cyanyuma. Noneho twinjiye gusuka temp kuri buri gicapo - kandi twanze icyiciro icyo aricyo cyose itandukaniro rirenga ± 10 ° C.
Intambwe ya 5: Gukemura nyuma yo Gutera - Aho Ubusugire Bwubuso bwatsinzwe cyangwa bwatakaye
Igiceri kibumba gitanga ishusho-ya net-ariko ntabwo ari net net. Ikimenyetso gikomeye cyo gufunga kiracyasaba CNC gutunganya. Niyo mpamvu duhuza gukina no gutunganya munsi yinzu. Ibyuma byacu bikozwe neza biva muri shakeout bigana kuri santere zitunganya imashini - nta bubiko buri hagati. Kubera iki? Kwinjiza neza mu buso butera hydrogène pinholes mugihe cyo kuvura ubushyuhe. Twirinze kandi guturika kurasa kubice bigenewe porogaramu ya AMS 5387; itangazamakuru ryangirika ryangiza hafi yubuso bwibinyampeke bukenewe mukurwanya umunaniro mubice bya pompe ya cobalt-alloy.
Gukora ibishishwa byerekana neza aho guta umucanga bidafite aho bihuriye no gushora imari mu ngengo yimari - mubisanzwe kubice bipima kg 0,5 kugeza kuri 50, ingano yumwaka kuva ku bihumbi 1.000 kugeza 50.000, hamwe nibikoresho birimo ibyuma byangiza, ibyuma bya karubone, ibyuma bitagira umwanda, hamwe na nikel irwanya nikel. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata ibishishwa by'ibishishwa ntabwo ari inzira yihariye ahubwo ni nk'umutwe umwe mu kugenzura neza-gutunganya-kurangiza. Ikintu cyose cyashushanyijeho ibicuruzwa twohereje gitwara ibintu byose byuzuye, ibipimo byemewe na CMM, hamwe namateka yubushyuhe bwanditse - kuva kumugati kugeza kugabanuka byanyuma. Nuburyo indangagaciro zumuvuduko zirokoka 20.000 PSI. Nuburyo winch center shaft rollers ikomeza kwiruka munsi ya 0,02 mm nyuma yamasaha 10,000. Precision ntabwo igerwaho murwego rumwe. Ifunze - intambwe ku yindi.
