Maitiro ekusarudza Carbide Giredhi

Nekuti hapana mwero wepasi rose unotsanangura mamakisi ecarbide kana maapplication, vashandisi vanofanirwa kuvimba nekutonga kwavo uye neruzivo rwekutanga kuti vabudirire.#base
Nepo izwi resimbi rekuti "carbide giredhi" richireva chaizvo tungsten carbide (WC) yakasimwa necobalt, izwi rimwe chetero rine chirevo chakafara mukugadzira: simende tungsten carbide yakasanganiswa nemabhandi uye mamwe marapiro.Semuyenzaniso, maviri anochinjika anopinza akagadzirwa kubva kune imwechete carbide zvinhu asi ane machira akasiyana kana mushure mekurapwa anoonekwa magiredhi akasiyana.Nekudaro, hapana kumira muchikamu checarbide uye coating musanganiswa, saka vatengesi vezvishandiso vakasiyana vanoshandisa mazita akasiyana uye nzira dzekuisa mumatafura ekirasi yavo.Izvi zvinogona kuita kuti zviome kumushandisi wekupedzisira kuenzanisa mamakisi, rinova dambudziko rakanyanya kuoma rakapihwa kuti kukodzera kwegiredhi recarbide kune yakapihwa application kunogona kukanganisa zvakanyanya mamiriro angangove ekucheka uye hupenyu hwematurusi.
Kuti ufambise maze iyi, vashandisi vanofanirwa kutanga vanzwisisa kuti carbide inogadzirwa nei uye kuti chinhu chimwe nechimwe chinokanganisa sei zvakasiyana zvemachining.
Iyo inotsigirwa chinhu chisina chinhu chekucheka chinopinza kana chakasimba chishandiso pasi pekuputira uye mushure mekurapa.Kazhinji inosanganisira 80-95% WC.Kupa hwaro zvinhu izvo zvinodiwa zvivakwa, vagadziri vezvinhu vanowedzera zvakasiyana-siyana alloying zvinhu kwairi.Iyo huru alloying chinhu ndeye cobalt (Co).Mazinga epamusoro ecobalt anopa kuomarara kukuru uye akaderera mazinga ecobalt anowedzera kuoma.Ma substrates akanyanya kuoma anogona kusvika 1800 HV uye anopa yakanakisa kupfeka kuramba, asi ane brittle uye anokodzera chete kugadzikana kwakanyanya.Iyo substrate yakasimba kwazvo ine kuoma kwe1300 HV.Aya ma substrates anogona kungogadzirwa neakadzika kucheka kumhanya, anopfeka nekukurumidza, asi anonyanya kushingirira kuvhiringika kucheka uye nemamiriro akashata.
Kuyera kwakaringana pakati pekuoma uye kuoma ndicho chinhu chakakosha pakusarudza alloy yeimwe application.Kusarudza giredhi rakanyanya kuoma kunogona kukonzera microcracks parutivi rwekucheka kana kutadza kutadza.Panguva imwecheteyo, mamakisi akaomesesa anopera nekukurumidza kana anoda kuderedzwa kwekucheka kukurumidza, izvo zvinoderedza kubereka.Tafura 1 inopa mamwe ekutanga nhungamiro yekusarudza iyo chaiyo durometer:
Mazhinji emazuva ano anoisa carbide uye maturusi ecarbide akaputirwa nefirimu rakatetepa (3 kusvika 20 microns kana 0.0001 kusvika 0.0007 inches).Iyo yekuputira kazhinji ine kabhoni layers yetitanium nitride, aluminium oxide uye titanium nitride.Uku kupfekedza kunowedzera kuomarara uye kunogadzira chinodzivirira chinopisa pakati pekuchekwa uye substrate.
Kunyangwe zvakangowana mukurumbira makore gumi apfuura, kuwedzera imwe yekuwedzera-yekuputira kurapwa kwave kuita indasitiri chiyero.Mishonga iyi inowanzova sandblasting kana dzimwe nzira dzekupukuta dzinotsvedzerera kumusoro uye kuderedza kukwesha, izvo zvinoderedza kupisa.Musiyano wemutengo unowanzo diki uye kazhinji unokurudzirwa kuti usarudze zvakarapwa zvakasiyana.
Kuti usarudze iyo chaiyo carbide giredhi kune imwe application, tarisa kune mutengesi kabhuku kana webhusaiti kuti uwane mirairo.Nepo pasina chiyero chepasi rose, vatengesi vazhinji vanoshandisa machati kutsanangura zvinokurudzirwa mashandiro emagiredhi zvichibva pa "kusiyana kwekushandiswa" kunoratidzwa semusanganiswa wemavara matatu ealphanumeric, seP05-P20.
Tsamba yekutanga inoratidza ISO zvinhu boka.Boka rimwe nerimwe rezvinyorwa rinogoverwa tsamba uye ruvara runoenderana.
Nhamba mbiri dzinotevera dzinomiririra kuoma kwakasiyana kwemagiredhi kubva pa05 kusvika ku45 mukuwedzera kwe5. 05 zvikumbiro zvinoda giredhi rakaoma kwazvo kune mamiriro akanaka uye akagadzikana.45 Zvishandiso zvinoda ma alloys akaomarara uye asina kugadzikana mamiriro.
Zvekare, hapana chiyero chezvinokosha izvi, saka zvinofanirwa kududzirwa sezviyero zvehukama mune imwe tafura yegiredhi maanoonekwa.Semuyenzaniso, mamakisi akaiswa P10-P20 mumakatalogi maviri kubva kune vakasiyana vatengesi anogona kuve nekuoma kwakasiyana.
Giredhi rakanyorwa P10-P20 mukirasi inotendeuka tafura inogona kuve nekuoma kwakasiyana pane giredhi rakanyorwa P10-P20 mukirasi yekugaya tafura, kunyangwe mukatalogi imwechete.Musiyano uyu unobva pakuti mamiriro akanaka anosiyana kubva pakushandiswa kuenda kune pakushandisa.Kushandura mashandiro kunoitwa zvakanyanya nemagiredhi akaomarara, asi kana kugaya, mamiriro akanaka anoda rimwe simba nekuda kwechimiro chepakati.
Tafura 3 inopa tafura yekufungidzira yealloys uye kushandiswa kwavo mukushandura mashandiro eakasiyana kuomarara, ayo anogona kunyorwa mukatalogi yemutengesi wemidziyo yekucheka.Mumuenzaniso uyu, kirasi A inokurudzirwa kune ese mamiriro ekutendeuka, asi kwete kune inorema yakavharwa kucheka, nepo kirasi D inokurudzirwa kune inorema yakakanganiswa kutendeuka uye mamwe mamiriro asina kunaka.Zvishandiso zvakaita seMachiningDoctor.com's Grades Finder inogona kutsvaga mamakisi uchishandisa iyi notation.
Sezvo pasina chiyero chepamutemo chehukuru hwematampu, hapana chiyero chepamutemo chemazita emhando.Nekudaro, mazhinji evakuru vecarbide ekuisa vatengesi vanoteedzera nhungamiro yemaitiro avo egiredhi.Mazita e "Classic" ari muchimiro chemavara matanhatu BBSSNN, uko:
Tsananguro iri pamusoro ndeyechokwadi muzviitiko zvakawanda.Asi sezvo iyi isiri ISO / ANSI chiyero, vamwe vatengesi vakazvigadzirisa ivo pachavo kuhurongwa, uye zvingava kuchenjera kuziva nezvekuchinja uku.
Kupfuura chero imwe application, alloys anoita basa rakakosha mukushandura mashandiro.Nekuda kweizvi, chimiro chakashandurwa chichava nesarudzo yakakura kwazvo yemagiredhi kana uchitarisa chero katalogi yevatengesi.
Kuwanda kwemagiredhi ekushandura magiredhi ndiwo mhedzisiro yemhando dzakasiyana dzekuchinja.Zvese zvinowira muchikamu ichi, kubva kunoramba kuchekwa (apo kuchekwa kunogara kunosangana neiyo workpiece uye haina kuvhunduka, asi inoburitsa kupisa kwakawanda) kusvika kunokanganisa kucheka (izvo zvinoburitsa kuvhunduka kwakasimba).
Huwandu hwemagiredhi ekutendeuka hunovharawo huwandu hukuru hwemadhayamita mukugadzira, kubva pa1/8 ″ (3 mm) yeSwiss type machines kusvika 100 ″ yekushandiswa kwakanyanya kwemaindasitiri.Nekuti kumhanya kwekucheka kunoenderanawo nedhayamita, magiredhi akasiyana anodiwa ayo akagadziridzwa kune yakaderera kana yakakwirira yekucheka kumhanya.
Vatengesi vakuru vanowanzopa akasiyana akatevedzana emagiredhi kuboka rega rega rezvinhu.Mune imwe neimwe nhevedzano, mamakisi anotangira kubva kumidziyo yakaoma yakakodzera kuvhiringika machining kune ayo akakodzera kuenderera mberi machining.
Pakugaya, huwandu hwemagiredhi anopihwa hudiki.Nekuda kwemaitiro anowanzo kupindirana echishandiso, vanocheka vanoda mamakisi akaomarara nekuomarara kwakanyanya.Nokuda kwechikonzero chimwe chete, kupfekedza kunofanira kuva kwakaonda, kana zvisina kudaro hakuzomiri.
Vazhinji vatengesi vanogadzira mapoka akasiyana-siyana ane mabhegi akaomarara uye machira akasiyana.
Pakuparadzana kana kukorokoza, kusarudzwa kwegiredhi kunogumira nekuda kwekucheka kukurumidza zvinhu.Kureva kuti dhayamita rinova diki sezvo kucheka kunosvika pakati.Nokudaro, kukurumidza kwekucheka kunoderedzwa zvishoma nezvishoma.Kana uchicheka wakananga pakati, kumhanya kunopedzisira kwasvika zero pakupera kwekuchekwa, uye oparesheni inova shear pane kuchekwa.
Naizvozvo, mamakisi anoshandiswa pakuparadzana anofanirwa kuenderana nehupamhi hwekumhanya kwekucheka, uye iyo substrate inofanirwa kunge yakasimba zvakakwana kuti ikwanise kumira pakupera kwekushanda.
Shallow grooves inosiyana kune mamwe marudzi.Nekuda kwekufanana kwekutendeuka, vatengesi vane sarudzo yakakura yekuisa grooving kazhinji vanopa akasiyana siyana emagiredhi kune mamwe mapoka ezvinyorwa uye mamiriro.
Pakuchera, kukurumidza kucheka pakati pechibooreso kunogara ku zero, uye kukurumidza kucheka pamucheto kunoenderana nehupamhi hwechibooreso uye nekukurumidza kutenderera kweiyo spindle.Magiredhi akagadziridzwa kumhanya kwekucheka kwakanyanya haana kukodzera uye haafanire kushandiswa.Vazhinji vatengesi vanopa mhando shoma chete.
Hupfu, zvikamu, uye zvigadzirwa inzira dzakasiyana makambani ari kusundira kuwedzera kwekugadzira.Carbide uye zvishandiso inzvimbo dzakasiyana dzekubudirira.
Kufambira mberi mune zvigadzirwa kwakaita kuti zvikwanise kugadzira chigayo checeramic chinoita zvakanaka pazasi chekucheka kumhanya uye kukwikwidza ne carbide end mill mune dzakasiyana siyana dzekushandisa.Chitoro chako chinogona kutanga kushandisa maturusi eceramic.
Zvitoro zvakawanda zvinokanganisa kufunga kuti maturusi epamusoro iplug-and-play.Zvishandiso izvi zvinogona kukwana mune zviripo zvibatiso zvematurusi kana kunyange muchigayo chimwe chete kana kutenderedza homwe sekuisa carbide, asi ndipo panoperera kufanana.
