Wakambofunga here nezve izvo zvinhu zvinoshandiswa pakuchera bhaketi?Muchikamu chino, tichakurukura zvinhu zvinonyanya kushandiswa mumapini, mativi, macheto ekucheka, dzimba uye mazino emabhakiti ekuchera.

Excavator Pins

Mapini ekuchera anowanzo kugadzirwa neAISI 4130 kana 4140 simbi.AISI 4000 akatevedzana simbi ndeye chrome molybdenum simbi.Chromium inovandudza corrosion resistance uye kuomesa, nepo molybdenum inonatsiridzawo simba uye kuoma.

Nhamba yekutanga, 4, inomiririra giredhi resimbi uye iyo huru alloy kuumbwa (munyaya iyi, chromium uye molybdenum).Chechipiri nhamba 1 inomiririra chikamu chezvikamu zvealloying, zvinoreva nezve 1% chromium uye molybdenum (nehuwandu).Nhamba mbiri dzekupedzisira ndeye carbon concentrations mu 0.01% increments, saka AISI 4130 ine 0.30% carbon uye AISI 4140 ine 0.40%.

Simbi yakashandiswa ingangove yakabatwa nekuomesa induction.Iyi nzira yekupisa yekupisa inoburitsa nzvimbo yakaoma nekupfeka kuramba (58 kusvika 63 Rockwell C) uye inogoneka yemukati yekuvandudza kuomarara.Ziva kuti bushings dzinowanzo gadzirwa nezvinhu zvakafanana nemapini.Mamwe mapini akachipa anogona kugadzirwa kubva kuAISI 1045. Iyi isimbi yepakati kabhoni inogona kuomesa.

Excavator Bucket Sides uye Kucheka Migero

Iyo bhaketi mativi uye blade zvinowanzogadzirwa neAr plate.Makirasi anonyanya kufarirwa iAR360 uye AR400.AR 360 ndeyepakati kabhoni yakaderera alloy simbi yakabatiswa kupisa kuti ipe yakanakisa kupfeka kuramba uye yakakwirira simba simba.Iyo AR 400 zvakare inorapwa kupisa, asi inopa kupfeka kuramba uye simba repamusoro regoho.Masimbi ese ari maviri akanyatso kuomeswa uye kudzikamiswa kuti awane yakakosha chigadzirwa mhando yebhaketi.Ndapota cherechedza kuti nhamba mushure meAR ndiyo Brinell kuoma kwesimbi.

Excavator Bucket Shell

Bucket housings inowanzogadzirwa kubva kuASTM A572 Grade 50 (dzimwe nguva inonyorwa A-572-50), inova A high simba low low alloy steel.Simbi inosanganiswa ne niobium uye vanadium.Vanadium inobatsira kuchengetedza simbi yakasimba.Iri giredhi resimbi rakanakira mabucket shells sezvo richipa simba rakanakisa uku richirema zvisingasviki simbi dzinoenzaniswa seA36.Zviri nyore zvakare weld uye chimiro.

Excavator Bucket Mazino

Kuti ukurukure kuti mazino ebhakiti anogadzirwa nei, zvakakosha kuti unzwisise kuti kune nzira mbiri dzekugadzira mazino ebhakiti: kukanda nekugadzira.Mazino ekukanda bhaketi anogona kugadzirwa nesimbi yakaderera alloy ine nickel uye molybdenum seyakanyanya alloying zvinhu.Molybdenum inonatsiridza kuomarara uye kusimba kwesimbi uye inogona kubatsirawo kuderedza dzimwe nzira dzegomba corrosion.Nickel inovandudza simba, kuoma uye inobatsira kudzivirira ngura.Izvo zvinogona zvakare kugadzirwa neisothermal quenched ductile iron iyo yakagadziriswa kupisa kuti ivandudze kupfeka kuramba uye simba rekuita.Mazino ebhakiti akaumbwa anogadzirwawo nesimbi inopisa-yakagadziriswa alloy, asi rudzi rwesimbi runosiyana kubva kumugadziri kusvika kumugadziri.Kurapa kwekupisa kunovandudza kupfeka kushanda uye kunowedzera simba rekuita.

Mhedziso

Mabhakiti ekuchera anogadzirwa nemhando dzakasiyana siyana, asi zvese izvi zvinhu ndezvemhando yesimbi kana simbi.Rudzi rwezvinhu zvinosarudzwa zvichienderana nekuti chikamu chinotakurwa uye chinogadzirwa sei.
