Inowanzoshandiswa mumagetsi-saw akapinza micheto uye mabhore.Izvi zvine simba kudarika zvigadziriso zvine ruzivo rwepamusoro-kabhoni simbi yagara ichishandiswa kubvira kuma1940 sezvo ichikwanisa kubata tembiricha yakakwira pasina kukanganisa simba radzo (kuoma).Ichi chivakwa chinobatsira HSS kucheka nekukurumidza kupfuura yakakwira kabhoni simbi, nekudaro izwi rekuti High Speed ​​​​Simbi.Pane tembiricha yemumba, imomo, kazhinji, yaikurudzira kurapwa kwekupisa, HSS wongororo, kazhinji, inoratidza kuomarara kwepamusoro (pamusoro peRockwell kuomarara 60) uye kukweshwa kwepikisi (kuzhinji kwakabatana ne tungsten uye vanadium zvirimo zvinowanzoshandiswa mukati. HSS) yakasiyaniswa uye yakajairika kabhoni uye mudziyo unogadzirira.

Applications

Iko kushandiswa kwekutanga kweHigh Speed ​​​​inogadzirira kunoramba kuri mukuunganidzwa kwezviridzwa zvakasiyana-siyana zvekucheka: madhiri, matepi, kucheka kucheka, mabheti emudziyo, hobbling (giya) cutter, akaona mipendero yakapinza, planer, uye mipendero yejointer, switch bits, zvichingodaro. ., zvisinei nekuti kushandiswa kwezvibhakera uye kicks bhaketi iri kuwedzera.

Kugadzirira kwekukurumidza kwakawana niche mumidziyo yakanaka yemaoko uko hupenyu hwavo hurefu hwakanyanya mukusimba kwakasanganiswa nekupikiswa kwakakwirira kwenzvimbo kwakavapa vakakodzera kune yakaderera-kumhanya maapplication anoda chinopinza, sematanda, maechi, matenga endege, uye mashizha ekicheni. uye mapanga anopeta anobva kuDhamasiko.

High speed simbi midziyo ndiyo inonyanya kuzivikanwa kushandiswa mukugadzira matanda, sezvo mwero wekugadzirwa kwebasa kunze kwemupendero unokurumidza kukurumidza kune maturusi anobatwa nemaoko, saka HSS ine mupendero wakareba kupfuura yakajairwa kabhoni simbi michina.

Types

Maumbirwo anokurumidza maamalgam anotora zvimiro zvawo kubva kune akati wandei simbi dzealloying dzakaiswa kune kabhoni simbi, yakafanana netungsten nemolybdenum, kana kubva musanganiswa wezviviri, dzimwe nguva zvine makomisheni akaparadzana.Vane nzvimbo mune yakawanda-zvikamu zvakaumbwa chimiro Fe - C - X umo X inoreva chromium, tungsten, molybdenum, vanadium kana cobalt.Chikamu che X chinoshandiswa kune chikamu chikuru pamusoro pe7 muzana, pamwe nepamusoro pe0.60 muzana kabhoni.

Tungsten-mhando makirasi (eg T1, T15) mune yakabatana manhamba system (UNS) anopihwa manhamba muchimiro cheT120xx, nepo molybdenum (semuenzaniso M2, M48) neT113xx dziri pakati pematayera emigwagwa.ASTM maitiro anoratidza 7 mafomu e tungsten uye 17 mafomu e molybdenum.

Kuwedzera kweanosvika gumi muzana yetungsten uye molybdenum pamwe chete inowedzera zvine pundutso kuomarara uye kusimba kwePamusoro Speed ​​inogadzirira uye inochengeta izvo zvivakwa pakupisa kwepamusoro kwakagadzirwa pakucheka simbi.

Inogona sei Kugara yakaoma?

Panguva iyo paunofunga nezveHSS yekucheka chiridzwa, funga kupisa.Iko kudziya kushoma kwaunogadzira (mumudziyo), iyo yakanyanya kukweverwa kunze chiridzwa chinogara.Paunenge uchipisa kubata HSS unoenda nayo kune imwe tembiricha (ikozvino uye zvakare inonzi kudziya kwakanyanya) kwenguva yakafanotaurwa.Izvi zvinopa HSS kuoma kwayo kwechokwadi, asi haina kusimba zvakanyanya.Zvadaro zvakatora tembiricha kuti "zvishatise kana kudhirowa".Izvi zvinowanzoitwa kanopfuura kamwe chete.Izvi zvinotakura kuomarara kwaunoda uye zvinopa HSS kusimba (zvese kuoma uye simba zvinodzorwa nemubatanidzwa mune izvo zvinhu).Tembiricha yekupisa haifanire kupfuudzwa pakushandisa kana kukudza mudziyo kana kuti inoomesa (relax).Izvi zvichasiyana kubva kune akati wandei anotarisisa (Rc) kune yakazara pasi pasi.Uku kujekeswa kwakakosha kwekudziya kunopa HSS mubayiro.
