Gravity zvachose mold inokandira fekitori mhinduro inoda zvinopfuura simbi yakanyungudutswa nesimbi. Vanoda kunyatso kudzora kupisa, kudzokororwa kwehupenyu hwehutongi, uye simbi yekuranga - kunyanya kana ichigadzira yakakwirira-yekutendeseka zvikamu zve hydraulic pombi, mavharuvhu enzvimbo yemafuta, kana mainjiniya emota winch masisitimu. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takakanda zvinopfuura zviuru gumi nezviviri zvakaomerwa simbi nesimbi zvikamu zvisingaperi kubva muna 2018- uye kutadza kwese, kudonha kwese kwese, chiitiko chediki-shrinkage chakatidzidzisa chinhu chimwe: kukanda giravhiti hakusi kungodira. Inodzorwa kusimbisa.
Chikonzero nei Permanent Mold Gravity Casting Ichiri Kukunda Yepakati-Vhoriyamu Maindasitiri Zvikamu
Vamwe mainjiniya vanofungidzira kukanda kwekudyara kunotsiva giravhiti yekusingaperi mold cast. Asi mukugadzirwa chaiko - kwete lab specs - chisingaperi mold inopa yakaomesesa dimensional kudzokororwa kwedzimba senge piston pombi silinda zvidhinha uye miviri yekumanikidza valve. Sei? Nekuti tembiricha yekuumbwa inogara mukati me ± 5 ° C mukati me300+ kutenderera kana uchishandisa preheated, yakavharidzirwa H13 chishandiso simbi molds. Kukanda jecha hakugoni kuenderana nekugadzikana ikoko. Investment casting inosuma ceramic shell kusiyanisa uye yakakwirira yakasara kushushikana. Isu tinoiyera: pane 420 mm × 280 mm × 120 mm pombi nheyo yekukandira, chisingaperi mold inobata GD&T chinzvimbo kushivirira kune ± 0.15 mm pamusoro pe500 mauniti; jecha rekukanda mavhareji ± 0.32 mm, ne 17% zvimedu nekuda kwekushanduka kwepakati.
Isu tinomhanyisa mitsetse miviri yakatsaurirwa giravhiti yechigarire mold-imwe ye ductile iron (ASTM A), imwe yeyakaderera-alloy simbi (A105N). Ose ari maviri anoshandisa yepasi-yekudurura gedhi, inotonhorera inoiswa pazvikamu zvakakosha, uye chaiyo-nguva yekutarisa thermocouple pamadziro emold. Hapana kufungidzira. Hapana "standard" kutenderera nguva. Chikamu chega chega chine chimiro chayo chekusimbisa chakamisikidzwa mune yedu process yekusimbisa mishumo.
Uko Mafekitari Mazhinji Anokundikana—uye Magadzirirwo Atinozviita
Mazhinji giravhiti yekusingaperi mold casting fekitori inodonha pamapoinzi matatu: kushatisa mold, kusapindirana preheat, uye kusakwana kwekusimudza dhizaini yekudyisa alloy-chaiwo. Isu takaona izvi pachedu pane AMS 5387 cobalt alloy pombi yedzimba odha. Yekutanga 19 castings yakaratidza subsurface porosity pedyo neflange-zvisinei nemakemikari akakwana. Root cause? Mold surface oxidation mushure me 42 cycles yakashandura kupisa kwekupisa. Solution: isu ikozvino recondition inoumba ega ega mapfuti makumi matatu neshanu tichishandisa alumina blasting uye proprietary borosilicate coating-inosimbiswa ne infrared emissivity bvunzo isati yadirwa yega yega.
Isu tinosimbisawo kuomarara preheat chirango. Zviumbwa zvedu hazvipindi muchoto chinotonhora. Dzinonyura pa280°C kwemaminetsi makumi mapfumbamwe, dzobva dzakwira kusvika pa320°C ±3°C uye dzinobata kwemaminitsi makumi mana nemashanu—dzakayerwa pamapoinzi matatu akadzika. Izvo hazvigone kutaurirana. Svetuka, uye unowana kutsemuka kunotyisa kana kukanganisa muT800-based components. Vatengi vanopa yavo mold vanowanzo furatira izvi. Tinoedza yavo isati yagamuchirwa.
Kubatanidzwa Ndiyo Yakanakira Chaiyo—Kwete Kungokandira
Iyo yechokwadi giravhiti yekusingaperi mold yekukandira fekitori mhinduro haimire pakuzunza. Inoenderera mberi kuburikidza nekugadzira, kupisa kupisa, uye metrology - zvese pasi pedenga rimwe. Panzvimbo yedu yeQingdao, imba yekukandira silinda inofamba yakananga kubva pakubvisa mold ichienda kuCNC ichibatidza Mazak Integrex i-200S. Hapana kunonoka kwezvinhu. Hapana kukanganisa kwekubata. Hapana coordinate system reset. Isu tinowanisa mabhora akakosha apo kukanda kuchiri mukati me50 ° C yetembiricha yesolidus-kudzikisa kukanganiswa ne40% zvichienzaniswa nekamuri-tembiricha machining.
Yedu yekubatanidza yakatwasuka inovhara mana akaturikidzana: zvinhu certification (zvese zvinopisa zvinoteedzerwa kuguyo bvunzo mishumo), yekukanda process yekusimbisa (ine radiographic uye ultrasonic sampling paASME B16.34), precision machining (CMM-yakasimbiswa kune ISO 2768-mK), uye inoshanda yekuyedza (hydrostatic pressure bvunzo inosvika mazana mana nemakumi mashanu mabhawa patsika-). Ndosaka mahwindi edu epakati shaft rollers emota dziri kunze kwenzira huru achiwana 100% yekutanga-pass goho-kunyangwe neasina-standard matepi uye akavhiringwa nzvimbo.
Kusarudza Mudiwa Wako Haisi Nezve Mutengo-Izvo Nezve Kufanotaura
Kana purojekiti yako ichida giravhiti yekusingaperi mold yekukanda fekitori inotakura nenguva, inobata GD&T pasina kupokana, uye inomisa njodzi dzekugadzira mireza isati yatanga-unoda kugona kwakanyorwa, kwete zvekushambadzira. Bvunza mibvunzo mitatu iyi usati wasaina:
- Unogona here kundiratidza matatu ekupedzisira PPAP mapakeji-kusanganisira mold kugadzirisa matanda uye machati tembiricha?
- Iwe unoita-in-process spectrographic analysis pane kupisa kwese, kana chete pamabhechi echinyorwa chekutanga?
- Kana kukanda kwatadza NDT, unopa mushumo wekugadzirisa-kana kungodzokorora?
Tinoita zvose zvitatu. Nguva dzese. Yedu ISO 9001: 2015-yakasimbiswa sisitimu inoteedzera pfuti yega yega mold, yega yega zvinhu zvakawanda, yega CMM probe point. Hapana kunze. Ndiwo matsigiro atinoita vatengi mhiri kweNorth America, Germany, neSingapore-nezero kunonoka kuendesa pamaodha epakati-vhoriyamu muna 2023.
Tichitarisa kumberi, tiri kuwedzera giravhiti yedu yekusingaperi mold yekukandira fekitori kuita maitiro akasanganiswa: pedyo-net-shape chisingaperi mold castings akapedzwa nelaser-anobatsira CNC kugaya kwecobalt-nickel alloys. Kwete nekuti ingano-asi nekuti data remumunda rinoratidza kuti inocheka mutengo wakazara ne22% pazvikamu zvinoda ese akaomarara geometry uye zvakanyanya kupfeka kuramba. Precision harisi dhipatimendi. Ndiko kutevedzana.
