Metal mold casting inopa kudzokororwa kunodzokororwa uko kukanda jecha kunodonha-kunyanya kune zvikamu zvakaita sehydraulic pressure valves, piston pump cylinder housings, uye cobalt-alloy nozzles inoda kushivirira kwakasimba, kuenderana microstructure, uye zero dimensional kudhirikirwa pamabhechi. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takamhanya pamusoro pe12,000 metal mold casting cycles kubva 2018-kwete sechiito chekufungidzira, asi kugadzirisa kukundikana kwechokwadi: warping mu T800 alloy pombi nheyo, porosity muAMS 5387 yekupwanya vharafu panguva yekupisa miviri yesimbi inoputika. Kukundikana kwega kwega kwakatidzidzisa zvinosiiwa nemabhuku: kudzora tembiricha yekuumbwa kunokosha kupfuura kuchena kwealloy; gating dhizaini inoraira kuneta hupenyu kupfuura kusimba kwesimba; uye pre-heat consistency inodzivirira 73% yezvimedu zvekutanga mu-high-nickel castings.
Nei Metal Mold Casting Inohwina Kana Kurongeka Kusina Kukurukurirana
Kukanda jecha kunoshanda kune yakaderera-vhoriyamu, yakaderera-kushivirira zvikamu. Asi kana chikamu chako chichifanira kubata ± 0.05 mm pane 320 mm dhayamita silinda imba-kana kurarama 15,000 psi pulsation muoiri musanganiswa wepombi-simbi yekukandira inova iyo yega nzira inoshanda. Simbi yaro yakasimba kana simbi yakakandwa molds inodzivirira kuwedzera kwemafuta, kuendesa yunifomu yekutonhodza mitengo, uye kubvisa kusiyanisa kunowanikwa mujecha rakasungwa. Isu tinoyera izvi zuva nezuva: masimbi edu esimbi anoratidza 42% kushoma shrinkage kusiyana pane yakaenzana jecha-cast mijenya, uye yedu Stainless simbi pombi nheyo dzinowana Cpk ≥1.67 pane yakakosha GD&T callouts-pasina yechipiri machining.
Mubayiro haungori dhimensional. Metal molds inogonesa kusimba kwekutungamira. Isu tinotungamira molds yakatwasuka yepiston housings, tichimanikidza simbi yekudyisa kumusoro kubva kuzasi. Izvi zvinobvisa centralline porosity muzvikamu zvakakora-chinzvimbo chekutadza chisingaperi mune jecha-cast yakaenzana. Kune cobalt-nickel alloys seAMS 5387, shanduko imwe chete yakaderedza voids yemukati ne91% mune yechitatu-bato NDT maodhita. Hapana kupfeka, hapana binder, hapana fungidziro-ingori fizikisi, inodzorwa.
Kwakunokundikana—Uye Nzira Yokunzvenga Nayo Misungo
Vamwe vanopokana simbi mold casting haina kuchinjika kune yakaderera-vhoriyamu inomhanya. Ivo vakarurama-kana iwe uchibata sekukanda jecha. Asi kuchinjika kunobva mukugadzirwa kwemaitiro, kwete zvinhu zvekuumbwa. Takaunza ma prototypes anoshanda mumazuva gumi nerimwe tichishandisa simbi yekumisikidza molds yeT800 alloy nozzles. Manomano acho? Pre-yakakodzera mold inoisa yakagadzirwa kubva kuH13 chishandiso simbi, isati yaomeswa kusvika 48 HRC, ine yakasanganiswa thermocouple ports yekutarisisa-chaiyo nguva cavity. Iyo data inodyisa zvakananga mukusimbisa yedu simulation-saka kudira kwechipiri kunoenderana nekutanga, kunyangwe pamakumi mashanu mayunitsi.
Iyo chaiyo mutengo musungo hausi wekushandisa-kuregeredza kusangana kwesimbi. Takambowana dhirowa rinotsanangura "ASTM A487 Giredhi CA6NM simbi isina tsvina" ye subsea pombi hwaro. Iyo spec yaive yechokwadi. Kuuraya kwacho kwanga kusiri: kutonhora kusingadzoreki kwe mold kwakakonzera kunaya kwe sigma chikamu pamwe nemiganhu yezviyo. Goho rakaderera kusvika pa38%. Mhinduro? Isu takachinjira kune inodzorwa-mhepo inodzima mukati memugodhi, tobva tawedzera 1050 ° C mhinduro anneal nekudzima kwemvura. Goho rakakwira kusvika pa94%. Chidzidzo: simbi mold casting haitsivi chirango chesimbi-inosimudzira mhedzisiro yayo.
Maitiro eQINGDAO QIANGSENYUAN Inobatanidza Kukandira Nekuita Kwechokwadi Kwenyika
Isu hatisiyanise kukanda kubva kune basa. Mainjiniya edu anoongorora yega yega GD&T furemu-kwete yekugadzira chete, asi yemasevhisi ekuremedza nzira. Muviri wevhavha yekumanikidza haisi chimiro chete; inzira yekushushikana. Saka isu tinodzvanya majeji ekuyeresa mukugadzira mold kuti mepu yemafuta emagetsi panguva yekusimba. Iyo dhata inotitaurira kwasara kushushikana kunotarisisa-uye kupi kwekuwedzera yemuno machining zororo kana post-kukanda kushushikana-yekudzoreredza kutenderera.
- Cobalt-alloy nozzles: Kanda mu-pre-heated H13 molds pa550°C, wozotonhodzwa nemhepo kudzivirira brittle intermetallic formation.
- Injiniya mota winch shafts: Jecha-akaumbwa macores akaiswa musimbi molds for hybrid geometry control-yakasimba ekunze goko, yakaoma yemukati spline mhango.
- Hydraulic silinda dzimba: Yakagadzirwa zvakananga kubva ku-se-cast state uchishandisa-mumba 5-axis CNC-hapana kugadzirisa zvakare, hapana datum shift.
Uku kubatanidzwa kunocheka nguva yekutungamira ne30% kupesana neanoteedzana kukanda + machining suppliers. Zvinotonyanya kukosha, inovimbisa kuteedzera: mijenya yega yega inotakura nhoroondo yakazara yekupisa, kuongororwa kwemakemikari, uye CMM yekuongorora mishumo-yakabatana neyakagadzirwa cert kubva kumagiyo akabvumidzwa.
Kusarudza Waunoshanda Naye—Kupfuura Bhurocha racho
Bvunza chero mutengesi nezve simbi yavo yekukandira. Wobva wabvunza zvinotevera zvinotevera: Ndeipi yako yakareba-inomhanya mold ye AMS 5387? Unosimbisa sei tembiricha yekuumbwa isati yadirwa yega yega? Unogona here kugovera ichangoburwa mushumo weFAI unoratidza as-cast vs. ekupedzisira zviyero pane chikamu chine ≥5 yakakosha GD&T maficha?
PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mhinduro dzedu dzinogona kuyerwa: 8,200 inodururwa pane imwe T800 nozzle mold; infrared pyrometer kusimbiswa pamapoinzi matatu pagoroti, yakadzikwa otomatiki; uye mishumo yeFAI inoratidza 0.012 mm avhareji yekutsauka pane gumi nemaviri-poinzi cylindrical runout ye280 mm pombi hwaro. Isu tinoshambadza izvi kwete sekushambadzira-asi nekuti simbi mold yekukanda budiriro inogara munhamba, kwete zvivimbiso.
Pazvikumbiro apo kutadza kunoreva kuderera, njodzi yekuchengetedza, kana kusateedzera mutemo-metal mold casting haisi sarudzo. Ndiyo yekutanga. Uye mudiwa akakodzera anoita mutsauko pakati peinodzokororwa nemazvo uye inodhura rework.
