Apo mainjiniya anotsanangura air set jecha kukanda yezvikamu zvesimbi zvine hunyanzvi, havasi kusarudza nzira yenhaka-vari kusarudza nzira yakasimbiswa, yakagadzikana yezvikamu zvinofanirwa kurarama nekudzvanywa kwakanyanya, kuchovha bhasikoro, uye kupfeka kweabrasive. Kusiyana nejecha rakasvibira kana kuti kwete-kubikira masisitimu eresin, kukanda jecha remhepo kunotsamira paunyoro hwemuchadenga uye tembiricha yakapoteredza kurapa binder-pasina ovheni, hapana zvinokonzeresa, hapana mhepo yekumanikidza. Kureruka uku kunovhara chaiyo tekinoroji nuance: kuwana ± 0.15 mm kushivirira pane 300-mm cobalt alloy pombi imba hakusi "kungoshandisa jecha." Iri nezve binder chemistry control, mold compaction kudzokorora, core geometry kuchengetedza panguva yekuzunza, uye post-cast dimensional kudzikamisa pamberi pekugadzira.
Takakanda anopfuura zviuru gumi nezviviri AMS 5387 cobalt alloy nozzles mumakore matatu apfuura - imwe neimwe iine makuriro emadziro ari pasi pe 4.2 mm uye mukati mekuyerera kwemukati inoda CMM-yakasimbiswa GD&T kuteedzera. Mubatch yega yega, iyo mhepo yekuseta maitiro yakaunza yakaderera yakasara kushushikana pane resin-yakasungwa dzimwe nzira, ichidzikisa post-machining kukanganisa ne37% papiston pombi silinda dzimba. Izvo hazvisi zvekufungidzira. Iyo inoyerwa pane yedu Zeiss CONTURA G2 yekuyeresa muchina wekuyeresa, wakadzikwa pachikamu chimwe nechimwe, unoteedzerwa kunhamba dzekupisa kwezvinhu uye mold lot IDs.
Nei izvi zvine basa? Nekuti mhepo yekukandira jecha haisi yekudzokera shure-inyanzvi inogonesa mishoni-yakakosha geometries uko microstructure kutendeseka uye dimensional fungidziro inodarika kumhanya mbishi. Funga nezve hydraulic pressure valve body: yakagadzirwa nesimbi yakasimba isina tsvina, ingada maawa gumi nemasere ekuwanda-axis milling uye kugadzira 62% tsvina yezvinhu. Kukandwa kuburikidza nejecha remhepo, iyo yepedyo-mambure chimiro inosvika iine 92% yekupedzisira misa yakasimba, shoma yemukati porosity (ASTM E155 Level 2), uye yunifomu dendritic spacing yakasimbiswa ne metallographic cross-section. Zvakaguma nei? Mutengo wakaderera, nguva ipfupi yekutungamira, uye-zvakakosha-zvirinani kuneta kuramba pakumanikidza maspikes pamusoro pe420 bar.
- Kuvimbika kwezvinhu: Air set binders (kazhinji sodium silicate + CO₂ activator kana organic ester masisitimu) inosuma isingaite kabhoni pickup. Iyo inochengetedza yakaomesesa chemistry windows inodiwa kune T800 cobalt-based alloys-apo kunyange 0.03% yakawandisa kabhoni inoshatisa kupisa kuomarara.
- Mold kugadzikana: Hapana exothermic reaction inoreva kuti hapana kuvhunduka kwekupisa kune mold panguva yekudira. Isu tinogara tichidurura 1100 ° C yakanyungudutswa cobalt-nickel mu molds inobatwa pa 22-28 ° C ambient-pasina blistering, hapana pamusoro tsinga.
- Dimensional consistency: Kuwedzera mold inofanotaurwa uye mutsara. Painjiniya mota winch centre shaft rollers (OD 215 mm, kureba 480 mm), tinobata kutenderera mukati me0.08 mm kuyambuka 100-mayuniti mijenya-pasina chechipiri-kuzorodza.
Vamwe vanogona kukakavara kuti jecha remhepo harina kupera kwepamusoro kwekukanda mari. Chokwadi-asi kushata kwepamusoro Ra 6.3 µm inokwana pakushanda kwekubatana panheyo dzepombi uye mavharuvhu akawanda. Pane basa rekupedzisa, tinobatanidza chaiyo CNC kutendeuka *mushure me* kukanda-kwete kare. Iyo inoteedzana inodzivirira machining kukanganisa kubva pakusara kwekunetsekana. Isu zvakare tinodzivirira iyo yakajairika musungo wekupfuura-kutsanangura simba rebinder: yakawandisa sodium silicate inowedzera mold brittleness uye musimboti kuputsika njodzi panguva yekubata. Kugadzira kwedu kwakaringana kunoshandisa 3.8% binder nehuremu, yakarapa maminetsi makumi mana nemashanu pa55% RH-yakagadziriswa mumwaka mitatu muunyoro hwemahombekombe eQingdao.
PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yedu air set jecha fekitari yekukandira inoshanda senge node imwe mukufambiswa kwakanyatsobatanidzwa-kwete nzvimbo yakasarudzika yekuwana. Kana mutengi achiendesa dhirowa yeisiri-yakajairwa cobalt alloy plug, maitiro edu anotanga nemetallurgical ongororo: Ko AMS 5387 ndiyo giredhi rakakodzera-kana kuti yakagadziridzwa T800 inounza zvirinani kuramba musevhisi yemvura yemunyu? Ipapo kunouya mold dhizaini simulation: Iyo gating system ichadyisa iyo yakatetepa-yakakomberedzwa chikamu ganda risati raoma? Ipapo ndipo patinovaka mapatani, kusanganisa jecha, uye kudira. Yese nhanho inodyisa data kumashure mune yedu ISO 9001-yakasimbiswa yemhando loop-material certs akaiswa, tensile mabara akaedzwa paASTM A781, ultrasonic ongororo inoitwa pamadziro ese> 25 mm gobvu.
Uku kubatanidzwa kunoburitsa izvo zvinonyanya kudiwa nevatengi: zvikamu zvinokwana, zvinoshanda, uye zvekupedzisira-kwete chete zvikamu zvinotakura. KuNorth American oilfield equipment OEMs, zvinoreva kuti mavharuvhu anorarama zviuru gumi nezviviri zvinotenderera pa350°F pasina kuvuza. Kune vavaki vemotokari dzeinjiniya dzeEurope, zvinoreva kuti winch shaft rollers inochengeta concentricity mushure memaawa mazana mashanu ekukwira bhasikoro. Kumaodzanyemba kwakadziva kumabvazuva kweAsia anounganidza pombi, zvinoreva kuti humburumbira dzimba dzinosvika dzine mamichina datum nzvimbo dzatove mukati me ± 0.05 mm - dzakagadzirira kusangana kwekupedzisira, kwete kushandazve.
Kana iwe uchiongorora vatengesi kuti vanyatso kukanda, bvunza mibvunzo mitatu: Vanogona kuratidza CMM mishumo yeyako chaiyo geometry-kwete generic samples? Ivo vanodzora kusanganiswa kwebinder, kurapa mold, uye shakeout paramita munguva chaiyo-kana kuvimba neruzivo rwemushandisi chete? Uye vanobatanidza kukanda data data kune yekupedzisira chikamu chekuita mukushandiswa kwemunda? Panzvimbo yedu, mhinduro kune vese vari vatatu ndihongu-uye yakanyorwa mune yega rekodhi rekodhi. Precision haina kuwanikwa munzvimbo yekugadzira michina. Zvinotangira mujecha.
