Tsananguro pfupi ye Carbon fiber 3D kudhinda

---

3D yakadhindwa kabhoni fiber ndiyo yechipiri yakanyanya kutsvakwa mushure mekuwedzera tekinoroji yekugadzira mushure mesimbi. Nekuda kweakasarudzika ehupfumi hweakabhoni fiber, senge: kureruka, simba rakakwira, kukwirira kwemagetsi kuitisa, kukwirira kwenyonganiso, zvikamu zvakagadzirwa ne3D kudhinda tekinoroji zvinowanzove nemhando yepamusoro uye yepamusoro kuita.

Carbon fiber 3D kudhinda tekinoroji

▶ Laser sintering tekinoroji
Hunhu hwesimba: Pfupi fiber yakasimbiswa nylon, PEEK, TPU uye zvimwe zveupfu zvinhu
Maitiro ekugadzirisa: Sanganisa ipfupi-yakatemwa kabhoni fiber uye nylon zvinhu mune chimwe chikamu, uye uone chakakosha kuumbwa ne laser sintering.


▶  Multi-jet yakanyungudika tekinoroji
Hunhu hwesimba: Pfupi fiber yakasimbiswa nylon, PEEK, TPU uye zvimwe zveupfu zvinhu
Maitiro ekugadzirisa: Kubudikidza nekupisa kwetepu remwenje, chikamu chemuchinjikwa chikamu chinounganidza kupisa kwakaringana kuti uone kusungunuka kunoumbwa pasi pechiito cheyakagadziriswa.

▶  FDM tekinoroji
Hunhu hwezvinhu: yakareba fiber yakasimbiswa PLA, nylon, PEEK uye zvimwe waya zvinhu
Maitiro ekugadzirisa: Iyo refu fiber inozadzwa mune yakajairwa waya neiyo FDM tekinoroji kusimudzira mhedzisiro.

Carbon fiber yekudhinda nzira

▶  Yakatemwa kabhoni fiber izere thermoplastic.
  Ipfupi-yakatemwa kabhoni fiber-yakazadzwa thermoplastics inodhindwa pane yakajairwa FFF (FDM) purinda ine thermoplastic (PLA, ABS kana nylon) yakasimbiswa netambo tudiki tudimburwa, kureva kabhoni fibers. Kune rimwe divi, kuenderera kwekabhoni fiber yekugadzira inzira yakasarudzika yekudhinda inoisa inoenderera kabhoni fiber masumbu mune akajairwa FFF (FDM) thermoplastic substrates.
Mapfupi-akachekwa kabhoni fiber-akazadza mapurasitiki uye enderera tambo inogadzirwa uchishandisa kabhoni fiber, asi mutsauko pakati pawo wakakura. Kunzwisisa mashandiro enzira imwe neimwe uye mashandisiro ayo akanaka kuchakubatsira iwe kuita sarudzo dzakanangana nezve zvekuita mukuwedzera zvigadzirwa.

Yakatemwa kabhoni tambo ndeyechokwadi inosimbisa zvinhu zveyakajairwa thermoplastics. Iyo inobvumidza makambani kudhinda zvinhu izvo kazhinji kazhinji zvisina simba pamatanho akakwirira esimba. Izvo zvinhu zvinobva zvasanganiswa ne thermoplastic uye musanganiswa unoguma unowedzerwa mupopu yeiyo melt filament yekugadzira (FFF) maitiro.
Pamakomputa anoshandisa nzira yeFFF, iwo musanganiswa wemasvosve akachekwa (kazhinji kabhoni fibers) uye zvakajairika thermoplastics (senge nylon, ABS kana polylactic acid). Kunyangwe maitiro eFFF achiramba akafanana, tambo dzakatemwa dzinowedzera kusimba uye kuomarara kwemuenzaniso uye nekuvandudza kudzikama kwechimiro, kupera kwepamusoro uye kunyatsoita.
Iyi nzira haisi yenguva dzose isina chakaipa. Dzimwe dzakatemwa faibha dzakasimbiswa filamendi inosimbisa kusimba nekugadzirisa iyo supersaturation yechinhu chine tambo. Izvi zvinogona kukanganisa zvakashata mhando yeiyo workpiece, ichideredza pamusoro pehunhu uye chikamu chikamu. Prototypes uye magumo-ekushandisa mativi anogona kugadzirwa kubva akachekwa kabhoni faibha nekuti inopa simba uye chitarisiko chinodikanwa pakuongorora kwemukati kana zvinhu zvinotarisana nevatengi.

Inoenderera kabhoni fiber yakasimbiswa zvinhu.
Inoenderera kabhoni fiber ndiyo chaiyo mukana. Iyi ndiyo isingadhuri mhinduro yekutsiva echinyakare simbi zvikamu neiyo 3D yakadhindwa yakasanganiswa zvikamu nekuti inowana yakafanana simba uchishandisa chete chidimbu chehuremu. Inogona kushandiswa kuisa zvinhu mu thermoplastics uchishandisa inoenderera filament kugadzira (CFF) tekinoroji. Prinda uchishandisa nzira iyi inoisa inopfuurira yakasimba simba tambo (semuenzaniso, kabhoni fiber, fiberglass kana Kevlar) kuburikidza neyechipiri yekudhinda kamwene muFFF yakabuditsa thermoplastic panguva yekudhinda. Kusimbisa tambo kunoita "musana" wechikamu chakadhindwa, ichigadzira yakaoma, yakasimba uye yakasimba simba.
Inoenderera kabhoni fiber haingowedzere simba chete, asi zvakare inopa vashandisi nekusimbisa kusarudza munzvimbo dzinoda kugadzikana kwepamusoro. Nekuda kweiyo FFF hunhu hwepakati maitiro, unogona kusarudza kuvaka pane yakaturikidzana-ne-rukoko hwaro.
Muchikamu chimwe nechimwe pane nzira mbiri dzekuwedzera: kusimbisa kusimbisa uye kusimbisa isotropic. Concentric inozadza inosimbisa iyo yekunze miganho yeiyo yega yega (yemukati neyekunze) uye kuwedzera muchikamu chine mushandisi-yakatsanangurwa nhamba yemacircule. Iyo isotropic yekuzadza inoumba unidirectional inoumbwa nekusimbisa pane yega yega, uye iyo kabhoni fiber yakarukwa inogona kuenzaniswa nekushandura nzira yekusimbisa pane iyo dura. Aya marongero akagoneswa anogonesa muchadenga, mota uye maindasitiri ekugadzira kuti asanganise zvinhu zvinoumbwa mukufambidzana kwavo munzira nyowani. Zvakadhindwa zvikamu zvinogona kushandiswa semidziyo uye zvigadziri (zvese izvi zvinoda kuenderera kabhoni fiber kuti inyatso fananidza simbi zvimiro.), senge zvishandiso panoperera ruoko, nyoro mukanwa, uye CMM zvigadziri.

Kushanda kwekabhoni fiber zvinhu muindasitiri yezvinhu
Nylon 12CF zvinhu, nyowani 3D yakadhindwa kabhoni fiber zvinhu zvine anosvika makumi matatu neshanu% kabhoni faibha, nekudaro yakanakisa muzvivakwa senge yekupedzisira yakasimba tensile ye35 MPa uye tensile modulus ye76 MPa. Nesimba rinoshanduka re7529 MPa, zvinokwana kutsiva simbi mukushandisa kwakawanda, zvakakwana kutsiva simbi mukushandisa kwakawanda, zvichiita kuti ive yakanaka kumotokari, muchadenga uye mamwe maindasitiri. Iyi kabhoni fiber yakasimbiswa thermoplastic inoshandiswa kuburitsa yakakwira mashandiro eprototypes ayo anogona kumira kuomarara kuyedzwa kwezvikamu zvekugadzira panguva yekugadzira dhizaini kusangana nezvinodiwa zvinodairwa kwenzvimbo yekugadzira uye zvinogona kushandiswa kumagetsi ekugadzira pane yekugadzira tambo.
OXFAB zvigadzirwa zvinopesana zvakanyanya nemakemikari uye kupisa, izvo zvakakosha kune yakakwira performance aerospace uye zvikamu zveindasitiri. Yakawedzera michina yekuyedza dhata inoratidza kuti OXFAB inogona kushandiswa kuzere, yakagadzirira-kushandisa-zvikamu zve 3D kudhinda. OPM irikushandisa kiyi yekuvandudza zvibvumirano nevatengi munzvimbo yeaerospace uye maindasitiri e3D yakadhindwa zvikamu zvevatengesi nevemauto ndege, nzvimbo uye maindasitiri mafomu, ayo anogona kudzikisira zvakanyanya huremu nemutengo.
Nhasi, munda wekuwedzera wekugadzira waputika, uye mamwe maprinta anopa kugona kudhinda pane kabhoni fiber. Kana iyo 3D indasitiri yekudhinda ichida kuwana yakawanda chikamu chemusika mumusika wekugadzira unosvika $ 100 bhiriyoni, tekinoroji yekudhinda ye3D inoda kuitiswa mune ese maitiro tekinoroji uye zvigadzirwa. Izvo zvakanakira zvakasiyana zvecarbon fiber zvinoratidza mukana wekuti chinangwa ichi chive chaicho. Kuti uve nechokwadi, kukwikwidzana neyechinyakare yekugadzira, zvinhu zvinoumbwa zvinosungirwa kuve chimwe chemasimba anotyaira kumashure kwe 3D kudhinda kuva tekinoroji yepamusoro.

Batanidza kuchinyorwa ichi: Tsananguro pfupi yekabhoni fiber 3D kudhinda tekinoroji uye mashandisiro ayo muzvikamu zveindasitiri

Dzokorora Chirevo: Kana pasina mirairo yakakosha, zvinyorwa zvese zviri pasaiti ino ndezvepakutanga. Ndokumbira uratidze kwakabva kudhindazve: https://www.cncmachiningptj.com/, thanks!
