Mukugadzirwa kwezvikamu zvemadhaimani, matambudziko akasiyana anogona kuitika.Pane matambudziko anokonzerwa nekusashanda zvakanaka panguva yekugadzira, uye zvikonzero zvakasiyana-siyana zvinoonekwa mukuita kweformula uye binder musanganiswa.Mazhinji ematambudziko aya anokanganisa kushandiswa kwechikamu.Mumamiriro ezvinhu akadaro, chikamu chedhaimani hachigone kushandiswa kana kusashanda zvakanaka, chinokanganisa kugadzirwa kwendiro yematombo uye kunyange kuwedzera mutengo wekugadzira.Mamiriro anotevera anowanzoita matambudziko emhando nezvikamu zvedhaimani:

Segment specifications isiriyo

Kunyangwe chikamu chedhaimani chiri musanganiswa wesimbi alloy uye dhaimondi yakanyudzwa neyakagadziriswa mold, chigadzirwa chekupedzisira chinopedzwa nekutonhora kudzvanya uye nekupisa kudzvanya sintering, uye zvinhu zvacho zvakagadziriswa, asi nekuda kwekusakwana kwekumanikidza uye tembiricha yekupisa panguva yekupisa. kugadziridzwa kwechikamu, kana Munguva yekupisa, tembiricha uye kudzvanywa kweiyo insulation uye kumanikidza hakuna kukwana kana yakawandisa, izvo zvinokonzeresa kusaenzana kwesimba pachikamu, saka nemusikirwo kuchave nezvikonzero zvekusiyana kwehukuru hweiyo. chikamu.Chiratidzo chakanyanya kujeka kukwirira kwechikamu uye nzvimbo iyo kudzvanywa hakuna kukwana.Ichava yakakwirira, uye kudzvinyirira kunenge kwakaderera.Naizvozvo, mukuita kwekugadzira, zvinonyanya kukosha kudzikamisa imwechete kudzvanywa uye tembiricha.Zvechokwadi, mukugadzirisa kusati kwaita, iyo inotonhora yechikamu inofanirawo kuyerwa;zvakare chenjerera kuti usatore mold isiriyo uye kuita kuti chikamu chibviswe.Kuonekwa.Ukuru hwedhaimondi bhiti hahuenderani nezvinodiwa, kuwanda hakuna kukwana, kuoma hakusviki zvinodiwa, kune marara muchikamu chekuchinja, uye kusimba kwebhiti hakuna kukwana.

 

 

 

Kusakwana density, segment bond inopfava

Mukati mekucheka dombo nedense uye nyoro zvishoma, iyo bit fracture ichaitika.Kutyoka kwakakamurwa kuita chikamu chekutyoka uye kutsemuka kwese.Hazvina mhosva kuti ndeupi rudzi rwekutsemuka, zvishoma zvakadaro hazvigoni kushandiswa zvakare.Zvechokwadi, kuputsika kwechikamu ndiyo muganhu.Paunenge uchicheka dombo, chikamu chisina kukwana density haizokwanisi kucheka nekuda kwekusakwana kwayo kweMohs kuomarara, kana chikamu chichapedzwa nekukurumidza.Kazhinji, kuwanda kwechikamu kunofanira kuvimbiswa.
Mamiriro ezvinhu akadaro anowanzo kukonzerwa nekushisa kwe sintering, kubata nguva, kusakwana kumanikidzwa, kusarudzwa kusina kunaka kwe bonding agent material, yakakwirira yedhaimondi yechikamu, nezvimwewo. Zvinowanzoitika, uye zvinozoonekwawo muzvinyorwa zvekare.Chikonzero chikuru kusashanda zvakanaka kwevashandi, uye kana iri fomula nyowani, zvikonzero zvizhinji zvinokonzerwa nekusanzwisisa kwemugadziri.Mugadziri anofanirwa kugadzirisa zvirinani segment formula uye kusanganisa tembiricha.Uye kumanikidza, kupa inonzwisisika sintering tembiricha uye kumanikidza.

Kuderera kwekushanda

Chikonzero chikuru nei chikamu chedhaimani chisingakwanisi kucheka ibwe ndechekuti simba harina kukwana, uye simba harina kukwana nekuda kwezvikonzero zvishanu zvinotevera:

1: Dhaimondi harina kukwana kana dhaimondi rakasarudzwa nderehurombo;
2: Kusvibiswa, zvakadai se graphite particles, guruva, nezvimwewo, zvinosanganiswa muchikamu panguva yekusanganiswa uye kutakura, kunyanya panguva yekusanganiswa, kusanganiswa kusina kuenzana kunogona kukonzera mamiriro aya;
3: Dhaimondi rakanyanyisa carbonized uye tembiricha yakakwira zvakanyanya, izvo zvinokonzeresa zvakakomba diamond carbonization.Munguva yekucheka, zvidimbu zvedhaimondi zviri nyore kudonha;
4: Chikamu chekugadzira dhizaini hachina musoro, kana kuti sintering process haina musoro, zvichikonzera kuderera kwesimba rekushanda uye shanduko yekuchinja (kana dhizaini yekushanda uye isiri-yekushanda haina kubatanidzwa zvakasimba).Kazhinji, mamiriro ezvinhu aya anowanzoitika mune zvitsva zvitsva;
5: Chishandiso chinosunga binder chakapfava kana kuti chakanyanya kuoma, zvichikonzera kushandiswa zvisina mwero kwedhaimondi nesimbi binder, zvichikonzera kuti diamond matrix binder itadze kubata hupfu hwedhaimondi.

Chikamu chinodonha

Pane zvikonzero zvakawanda zvekuti musoro wekucheka udonhe, senge tsvina yakawandisa, yakanyanya kana tembiricha yakadzikira, kupfupika kwekuchengetedza kupisa uye kudzvanywa kwekubata nguva, isina kukodzera fomula ratio, isina musoro welding layer, dhizaini yekushanda yakasiyana uye isiri-kushanda formula. kutungamirira kuhutano hwekuwedzera kwekushisa kwezviviri Zvakasiyana, kana chikamu chacho chatonhodzwa, shrinkage stress inoitika mubasa rekushanda uye kusashanda kwekubatanidza, iyo inozopedzisira yaderedza simba rechikamu, uye pakupedzisira inokonzera kuti chikamu chiwe.Zvikonzero izvi ndizvo zvikonzero zvinoita kuti chidimbu chedhaimondi chidonhe kana kuti sahwa ribude mazino.Kuti tigadzirise dambudziko iri, tinofanira kutanga tive nechokwadi chokuti hupfu hwanyatsokuchidzirwa zvakaenzana uye pasina tsvina, uye zvino kuenzanisa kumanikidzwa kunonzwisisika, tembiricha, uye nguva yekuchengetedza kupisa, uye edza kuona kuti thermal kuwedzera coefficient yebasa rekushanda uye kwete. -working layer iri pedyo nemumwe.
Munguva yekugadzirisa zvikamu zvemadhaimani, mamwe matambudziko angamuka, akadai sekushandisa zvakanyanya, jamming, eccentric wear, etc. Matambudziko mazhinji haasi dambudziko rechikamu chete, asi angave akabatana nemuchina, rudzi rwematombo, nezvimwewo.
