Carbide isimbi yakaoma kwazvo, yechipiri chete kune dhaimondi mukuoma uye yakanyanya kuoma kupfuura simbi nesimbi isina tsvina.Panguva imwe cheteyo, inorema zvakafanana nendarama uye inorema kaviri kupfuura simbi.Mukuwedzera, ine simba rakanakisisa uye elasticity, inogona kuchengetedza kuoma pakupisa kwepamusoro, uye haisi nyore kupfeka.Naizvozvo, zvinhu zvecarbide zvinowanzo shandiswa muminda yekugadzira maindasitiri senge simbi yekugadzirisa maturusi uye mold.

Chikamu Chekutanga: Chii chinonzi carbide zvinhu?
Cemented carbide inogadzirwa ne tungsten carbide uye cobalt.Tungsten carbide chinhu chine yakakwira kunyungudika.Inoda kukuyiwa kuita upfu uye yobva yagadzirwa nekupisa kwekupisa uye kusimba, uye cobalt inowedzerwa sechinhu chinosunga.Tungsten inouya zvakanyanya kubva kuChina, Russia neSouth Korea, nepo cobalt inobva kuFinland, Canada, Australia neCongo.Naizvozvo, kugadzira superhard alloys kunoda kudyidzana kwepasi rose kushandisa ichi chinoshamisa kune akasiyana siyana minda.Anowanzo shandiswa simende carbides akakamurwa muzvikamu zvitatu zvichienderana nekuumbwa kwavo uye maitiro ekuita: tungsten-cobalt, tungsten-titanium-cobalt, uye tungsten- titanium-cobalt (niobium).Inonyanya kushandiswa mukugadzira tungsten-cobalt uye tungsten-titanium-cobalt simende carbide.
Kuti ugadzire super hard alloy, zvinodikanwa kukuya tungsten carbide necobalt kuita hupfu hwakatsetseka, uye kupisa uye kusimba pakupisa kwakanyanya (1300 ° C kusvika 1500 ° C) kuomesa zvinhu.Cobalt inowedzerwa sechinhu chekubatanidza kubatsira tungsten carbide zvimedu zvinonamatira kune mumwe nemumwe.Mhedzisiro yacho isimbi yakasimba zvikuru ine nzvimbo yakanyunguduka ye 2900 ° C, ichiita kuti ive yakasimba kune tembiricha yepamusoro uye yakanyatsokodzera kushandiswa kwepamusoro-tembiricha.
Chikamu Chechipiri: Chii chinonzi kushandiswa kwezvinhu zvecarbide?
Cemented carbide ine huwandu hwakawanda hwekushandisa.Mundima yekugadzira maindasitiri, inoshandiswa zvakanyanya mukugadzira maturusi ekucheka ekugadzira simbi senge CNC yekuchera maturusi, CNC milling michina, uye CNC lathes.Uye zvakare, inogona kushandiswa kugadzira molds emagaba ealuminium akadai sekofi yemumagaba uye zvinwiwa, poda yekuumba maumbirwo emotokari injini zvikamu (sintered parts), uye molds yezvigadzirwa zvemagetsi senharembozha.
Panyaya yekugadzira uye kugadzirisa, kukosha kweiyo super hard alloy inozviratidza.Nekuda kwekuomarara kwayo uye simba, superhard alloys anoshandiswa zvakanyanya mumichina yekugadzira senge simbi yekucheka maturusi, maturusi ekuchera, milling michina uye lathes.Mukuwedzera, inogona kushandiswa kugadzira aruminiyamu inogona kuumba yekofi yemumagaba uye zvinwiwa, poda yekuumba maumbirwo emotokari injini zvikamu (sintered parts), uye molds yezvigadzirwa zvemagetsi sefoni, nezvimwewo.
Nekudaro, superhard alloys haina kuganhurirwa kumunda wesimbi kugadzirisa uye kugadzira.Inogonawo kushandiswa pakupwanya dombo rakaoma, sekugadzirwa kwenhovo, uye kucheka kwemigwagwa yeasphalt nemimwe minda.Uye zvakare, nekuda kwehunhu hwayo hwakanaka, superhard alloys inogona zvakare kushandiswa zvakanyanya mune mamwe minda yeCNC machining.Semuenzaniso, midziyo yekuvhiya inoshandiswa mundima yekurapa, mabara uye warheads mumunda wemauto, zvikamu zveinjini uye mashizha eturbine endege mumunda wemuchadenga, nezvimwe.
Pamusoro pekushandisa muindastiri, super hard alloys zvakare inoita basa mumunda wekutsvaga kwesainzi.Semuyenzaniso, inogona kushandiswa kugadzira diffraction rods muX-ray uye optical research, uye sechinhu chinokonzeresa mukudzidza kwemakemikari kuita.
Chikamu chechitatu: Chii chakaoma mu carbide chikamu machining?
Kugadziriswa kwecemented carbide hakusi nyore uye kune matambudziko mazhinji.Chekutanga, nekuda kwekuoma kwayo kwakanyanya uye brittleness, nzira dzechinyakare dzekugadzirisa dzinowanzo kunetsa kuzadzisa zvinodiwa uye dzinogona kutungamira nyore kune hurema hwakadai sekutsemuka uye deformation muchigadzirwa.Chechipiri, simende carbide inoshandiswa muminda yepamusoro-soro, saka zvinodikanwa zvemachining accracy zvakakwirira kwazvo.Munguva yekugadzirisa, zvinhu zvakawanda zvinofanirwa kutariswa, senge maturusi ekucheka, zvigadziriso, maitiro paramita, nezvimwe, kuve nechokwadi chechokwadi chechigadzirwa.Chekupedzisira, izvo zvemhando yepamusoro zvinodiwa zvecemented carbide zvakare zvakakwirira kwazvo.Nekuda kwekunyanya brittleness, iyo nzvimbo inokuvadzwa zviri nyore, saka nzira dzakakosha dzekugadzirisa uye midziyo (senge ultra-precision grinders, electrolytic polishers, etc.) inoda kushandiswa kuve nechokwadi chepamusoro.
Muchidimbu, cemented carbide iri kuwedzera kushandiswa muCNC machining, ichiita basa rakakosha mukuvandudza hunyanzvi hwekugadzira uye kunaka kwechigadzirwa mumakina, zvemagetsi, makemikari, aerospace uye mamwe maindasitiri.GPM ine advanced processing equipment uye tekinoroji inogona kugadzira supercarbide zvikamu zvakanaka uye nemazvo. .Iyo yakasimba yemhando yekudzora sisitimu panguva yekugadzirisa inovimbisa kuti chikamu chimwe nechimwe chinosangana nezvinodiwa nevatengi uye zviyero.
