Kana mainjiniya achinge ataura magiya emapombi ehydraulic, madhiraivha ewinji, kana mavharuvhu anosimudzira, haawanzotanga nehupfu simbi. Mazhinji anosvika pekutanga simbi yekunyepedzera kana CNC-akagadzirwa blanks-kusvikira dimensional kugadzikana, kupfeka kuramba, uye mutengo wakakwana pachikamu chatanga kushandura Calculus. Ndiko uko kwakatsaurirwa upfu metallurgy giya fekitari inomira kuva imwe nzira-uye inova iyo yega sarudzo ine musoro.
KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takaona shanduko iyi tega mumakondinendi matatu. Pombi yekuNorth America OEM yakadzikisa giya rekutsiva frequency ne40% mushure mekuchinja kubva kusimbi yakanyungudutswa kuenda kuAMS 5387 cobalt alloy PM magiya mudzimba dzadzo dzepombi dzepiston dzakakwirira. Mutengesi wemotokari dzeinjiniya wekuEurope akacheka nguva yekufambisa nemazuva gumi nerimwe-kwete nekumhanyisa machining, asi nekubvisa mashandiro echipiri mashanu zvachose. Idzi dzaive dzisiri budiriro yedzidziso. Ivo vakabva pakudzora density gradients mukati me ± 0.02 g/cm³, vakabata pitch dhayamita kushivirira kusvika ± 0.015 mm pa 16-module spur magiya, uye kuwana roughness Ra ≤ 0.8 µm—as-sintered.
Kurongeka kwechokwadi muhupfu simbi hakusi kwekutsikirira huruva yesimbi uye kuidaidza kuti yaitwa. Inotanga neraw material certification: batch imwe neimwe yeT800 cobalt-based powder inotakura kutevedza kwakazara kune atomization parameters, oxygen content (≤120 ppm), uye particle size distribution (D50 = 18-22 µm). Isu tinoramba hupfu kunze kwehwindo iro-kunyangwe mutengesi akapa 15% kuderedzwa. Sei? Nekuti 0.3% density mutsauko pamudzi wegiya unogadzira kudonha kwe22% mukukotama hupenyu hwekuneta pasi pekutakura cyclic. Isu tinosimbisa izvo zuva nezuva tichishandisa Archimedes 'musimboti uye micro-CT scanning pane emuenzaniso cores-kwete chete pazvikamu zvekupedzisira, asi pagirinhi, brown, uye sintered nhanho.
Yedu yekugadzira pasi inosanganisa matatu asingagone kutaurirana akawanda zvitoro zvePM anobata semasevhisi akasiyana:
- Kudzorwa mamiriro ekunze ine chaiyo dova rekutonga (−40 ° C kusvika -25 ° C) uye nitrogen / hydrogen musanganiswa-yakakosha kuchengetedza carbide kupararira mumakobalt alloys pasina decarburization.
- In-die coining inoshandiswa panguva yejection, kwete senge post-process, kuendesa ± 0.008 mm runout control pamagiya bores pasina kugaya.
- Kushanda kupisa kurapwa yakabatanidzwa zvakananga mushure mekupisa: mhinduro annealing pa1180 ° C + kukurumidza kudzimwa kweAMS 5387, ichiteverwa nekuchembera pa845 ° C-kuzadzisa Rockwell C 42-46 uchichengetedza giya zino geometry.
Vamwe vanogona kupokana kuti CNC-akagadzirwa magiya anopa yepamusoro yepamusoro kupedzisa. Chokwadi - kune ma geometries ari nyore. Asi kana mutengi akakumbira mazino makumi maviri nemaviri, 3.5-module helical giya ine 25 ° helix angle, yemukati spline, uye press-fit bore - yakagadzirwa kubva yakasimba T800 bar - math inoshanduka. Kukohwa kwezvinhu kunoderera kusvika pa38%. Nguva yekutenderera inodarika maminitsi makumi mapfumbamwe nemaviri. Tool kupfeka spikes pashure 17 zvikamu. Yedu PM maitiro anoburitsa giya rimwechete mune imwe compacting kutenderera, iine 91% kushandiswa kwezvinhu, gumi nemana-maminetsi takt nguva, uye zero tooling kupfeka pakati pemabhechi. Iyo giya inosangana neAGMA Q12 uye ISO 1328-1 Kirasi 7-pasina kukuya.
Isu hatisundire simbi yehupfu paisiri yake. Kana chikumbiro chako chichida giya rekudzokera kumashure kusimba kupfuura 0.02 mm patembiricha yekushanda, kana kana kuremerwa kwako kuchisanganisira kuvhunduka kunopfuura 3 × yakayerwa torque, tinokuudza kumberi: forged + yekupedzisa-ivhu ichiri nzira yako yakanaka. Asi kune yepakati-vhoriyamu inomhanya (500-10,000 pcs/gore), yakakwirira-inopfeka nharaunda (≥200 MPa yekubata kushushikana), kana masisitimu ane huremu, ruzha, kana gungano rakaomarara nyaya-PM inopa inoyerwa ROI. Mumwe mugadziri wemidziyo yemafuta ekuSoutheast Asia akatsiva 12-zvidimbu zvakasungwa magiya anotakura nekamwe-chidimbu PM magungano. Huremu hwakaderera ne37%. Basa regungano rakadonha kubva ku42 maminitsi kusvika ku9. Uye vibration amplitude pa 1800 rpm yakaderera ne 63% - kuyerwa pa-site ne laser Doppler vibrometry.
Chii chinoparadzanisa anokwanisa upfu metallurgy giya fekitari kubva kuchitoro chekutsikisa zvinhu hausi kugona - ndeye dura-chaiyo yekutadza kuongororwa. Kana giya remutengi rakatadza nguva isati yakwana mupombi yepasi pegungwa, isu hatina kungoitsiva. Isu takayambuka-chikamu chikamu chakakundikana, mepu porosity masumbu achipesana nekushushikana contours, correlated oxide inclusions ne sintering atmosphere matanda, uye nekugadzirisa zvakare kufa cavity venting pateni. Mhedzisiro: zero kukundikana kwemunda kwemwedzi gumi nemasere uye 47,000 maawa ekushanda.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda kubva kuQingdao-kwete seyakajairwa-chinangwa chekuvamba, asi seyakanyatso mubatanidzwa wezvikamu zvemasisitimu uko magiya asiri kungofamba zvikamu. Izvo zvinhu zvekudzivirira zvinomanikidza. Torque transmission anchors. Kuneta-yakakosha nzvimbo. Isu tinovagadzira nenzira iyoyo-kubva pakusarudzwa kwehupfu kuburikidza nekusimbisa kushanda. Nzvimbo yedu inobata ISO 9001: 2015 uye AS9100D zvitupa, asi chinonyanya kukosha mashandisiro atinoita: ngarava dzese dzegiya dzine mishumo yakazara, density matanda, kuomarara profiles mhiri kwezino nemidzi, uye metallurgical micrographs yezvikamu zvakakosha.
Iyo remangwana repamusoro-chaiyo giya kugadzira haisi kusarudza pakati pePM uye machining. Iko kuvabatanidza nehungwaru-kushandisa PM yepedyo-net geometry uye kurongeka kwechimiro, wozoshandisa kushoma, kwakanangwa CNC kupedzisa chete painoda nzvimbo dzinoshanda. Iyo nzira yakasanganiswa — yekukandira-machining synergy — ndipo pari pari zvino tarisiro yedu yeR&D. Kwete kutsiva maitiro, asi kubvisa kukanganisa.
