Kedu ụlọ ọrụ nwere ike iji mma okirikiri carbide simenti mee ihe?

Igwe okirikiri cemented carbide, nke na-egosipụta ike siri ike, nguzogide na-eyi, na nguzogide oke okpomọkụ, abụrụla ihe eji eme ihe na ngalaba nhazi ụlọ ọrụ, yana ngwa na-ekpuchi ọtụtụ ụlọ ọrụ achọrọ. Ihe na-esonụ bụ nyocha site n'echiche nke ọnọdụ ụlọ ọrụ, ihe nhazi chọrọ, na uru agụba:

I. Ụlọ ọrụ nhazi ígwè: Ngwá ọrụ isi maka ịkpụ na ịkpụ

1. Ubi Nrụpụta Mechanical
   Ihe ngosi ngwa: Ntugharị na igwe igwe nke akụkụ akpaaka (ngwongwo engine cylinder, shafts gear) na ngwa ngwa igwe (mgbanaka na-ebu, ihe ọkpụkpụ).
   Uru agụba: Igwe okirikiri cemented carbide (dị ka eriri mkpuchi CBN) nwere ike iguzogide oke okpomọkụ na nrụgide n'oge ịkpụ ọsọ ọsọ. Maka ígwè (dị ka 45 # ígwè, ígwè alloy), nkwụsịtụ ziri ezi ruru IT6 - IT7 ọkwa, na elu roughness Ra ≤ 1.6μm, na-emezu ihe nhazi chọrọ nke kpọmkwem akụkụ.
2. Mmepụta Aerospace
   Ngwa a na-ahụkarị: Egwe ọka titanium alloy landing gears na aluminom alloy fuselage frames.
   Ihe achọrọ nka na ụzụ: Ọtụtụ ihe ikuku ikuku bụ alloys ọkụ dị ike. Akara okirikiri kwesịrị inwe ihe mgbochi mgbochi (dịka mkpuchi TiAlN) iji zere mmeghachi omume kemịkalụ n'etiti agụba na ihe n'oge nhazi. Ka ọ dị ugbu a, imewe akụkụ arc nwere ike belata mbelata mkpọtụ ma hụ na nkwụsi ike nhazi nke akụkụ ndị nwere mgbidi dị mkpa.

II. Nhazi osisi na ngwá ụlọ: Ụkpụrụ maka ịkpụ nke ọma

1. Nrụpụta ngwá ụlọ
   Ihe ngosi ngwa: Ịcha bọọdụ njupụta na bọọdụ multi-layer, na nhazi mortise na tenon nke ngwá ụlọ osisi siri ike.
   Ụdị agụba: Mpempe akwụkwọ nchara okirikiri nke carbide cemented mara mma (dị ka YG6X) nwere akụkụ dị nkọ na nke na-agaghị eyi. The ọnwụ ọsọ nwere ike iru 100 - 200m / s, na ọrụ ndụ nke otu agụba bụ 5 - 8 ugboro ogologo karịa nke elu-ọsọ ígwè agụba, adabara uka mmepụta nke mbadamba.
2. Nhazi ala osisi
   Ihe ndị chọrọ Pụrụ Iche: Ire-na-groove ịkpụ ala osisi laminated chọrọ ka agụba nwee mmetụta dị elu. Nhazi okirikiri nke nwere ike na-ebu okirikiri nwere ike ibelata ihe egwu nke ịpịa ihu. Ka ọ dị ugbu a, teknụzụ mkpuchi (dị ka mkpuchi diamond) nwere ike belata okpomọkụ n'oge ịkpụ ma zere carbonization nke akụkụ osisi.

III. Nkume na ihe owuwu ụlọ: ihe na-edozi maka ihe siri ike na nke na-esi ike

1. Ụlọ ọrụ Nhazi Nkume
   Ngwa ndapụta: Ịcha granite na mabụl siri ike blocks, na chamfering nhazi nke seramiiki tile.
   Njirimara agụba: Mpempe okirikiri nwere WC-Co cemented carbide matrix jikọtara ya na polycrystalline diamond compact (PDC) nwere ike siri ike nke HRA90 ma ọ bụ karịa, nwere ike igbutu okwute na ike Mohs n'okpuru 7, na ịcha arụmọrụ dị 30% dị elu karịa nke igwe igwe silicon carbide ọdịnala.
2. Injinia ihe owuwu
   Ikpe a na-ahụkarị: Ịkpọ ala na ịkwanye akụkụ ndị a kpara akpa (dị ka ihe ndị nwere ike ime akwa akwa).
   Nka na ụzụ pụta ìhè: Nhazi usoro mmiri jụrụ oyi nke eriri okirikiri nwere ike iwepụ okpomọkụ n'oge, na-ezere ihe mgbawa n'ihi oke okpomọkụ. Ka ọ dị ugbu a, nhazi ihu serrated na-eme ka ike kụrie ihe na-emebi emebi ma na-ebelata mmetọ uzuzu.

IV. Eletrọnịkị na nrụpụta nkenke: Igodo maka nhazi ọkwa Micron

1. Nkwakọ ngwaahịa Semiconductor
   Ihe ngosi ngwa: Ịcha ihe ndị na-esi ísì ụtọ na silicon, na nkwụsị nke bọọdụ sekit PCB.
   Nkọwapụta agụba: eriri okirikiri carbide cimented dị obere (ọkpụrụkpụ 0.1 - 0.3mm) jikọtara ya na spindles dị elu nwere ike ijikwa ego chipping n'ime 5μm mgbe ị na-egbutu silicon wafer, na-ezute ihe nhazi ọkwa micron nke nkwakọ ngwaahịa mgbawa. Ọzọkwa, akwa mkpuchi mkpuchi nke agụba nwere ike hụ na nha nha nha n'oge ịkpụ ogbe.
2. Nhazi akụkụ nkenke
   Ngwa a na-ahụkarị: Ngwunye ngwa mmegharị elekere na ngwa ịwa ahụ pere mpe maka ngwaọrụ ahụike.
   Uru Embodiment: N'ọnụ nke agụba okirikiri bụ mirror-egbu maramara (roughness Ra ≤ 0.01μm), n'ihi ya, ọ dịghị mkpa nke abụọ egweri nke akụkụ elu mgbe nhazi. Ka ọ dị ugbu a, nnukwu siri ike nke carbide cemented nwere ike izere nrụrụ n'oge nhazi nke obere akụkụ.

V. Nhazi plastik na rọba: nkwa maka ịkpụzi nke ọma

1. Mmepụta ihe nkiri plastik
   Ihe ngosi ngwa: Mwepu ihe nkiri BOPP, na ibelata mpempe akwụkwọ plastik.
   Nhazi agụba: agụba mgbawa okirikiri na-eji atụmatụ ihu akụkụ rake na-adịghị mma iji belata ihe omume rọba na-arapara na agụba. Ejikọtara ya na usoro njikwa okpomọkụ mgbe niile, ha nwere ike ịnọgide na-enwe ọnụ ọnụ na okpomọkụ nhazi nke 150 - 200 ℃, na slitting ọsọ ruru 500 - 1000m / min.
2. Nhazi ngwaahịa rọba
   Ngwa a na-ahụkarị: Ịcha taya taya, na ịpụ akàrà.
   Nka na ụzụ Uru: Isi ike nke cemented carbide okirikiri blanking blanking ruru HRC75 - 80, nke nwere ike idebe ihe na-agbanwe agbanwe dị ka nitrile rubber 50,000 - 100,000 ugboro ugboro, na ọnụ na-eyi ego ≤ 0.01mm, na-eme ka ngwaahịa ahụ na-agbanwe agbanwe.
