Quilted seamless pombi imhando yepamusoro chaiyo simbi pombi zvinhu mushure mekutonhora kudhirowa kana kupisa kukunguruka.Nekuti hapana oxide layer pamadziro emukati nekunze epombi yesimbi yakanyatsojeka, [1] pasi pekumanikidzwa kukuru pasina kubuda, kurongeka kwepamusoro, kupera kwepamusoro, kutonhora kukotama pasina deformation, kupisa, kubata pasi pasina kuputika uye zvichingodaro, inonyanya kushandiswa. nokuda kwekugadzirwa kwepneumatic kana hydraulic components, zvakadai semasilinda kana masilinda, ayo anogona kunge asina musono.Iyo kemikari inoumbwa ye quilted seamless chubhu ndeye kabhoni C, silicon Si, manganese Mn, sarufa S, phosphorus P, chromium Cr.
Quilted seamless pombi inotora kugadzirisa tekinoroji
Iyo quilted seamless pombi inogadziriswa nekukunguruka.Nekuda kwekusarira kudzvanyirira kushushikana pamusoro pedenga repamusoro, zvinobatsira kuvhara madiki akatsemuka pamusoro uye kudzivirira kuwedzera kwekukukurwa.Inogona kunatsiridza kusadzivirirwa kwepamusoro uye kunonoka chizvarwa kana kuwedzera kwekuneta kwakatsemuka, kuitira kuvandudza kuneta kwesimba re quilted simbi pombi.Nekukunguruka kuumba, inotonhora inoshanda inoomesa layer inoumbwa pane inotenderedza, iyo inoderedza elastic uye purasitiki deformation yekusangana kwepamusoro peya yekukuya, nekudaro inovandudza kusapfeka kwemukati wemukati wepombi yesimbi yakavharwa uye kudzivirira kupisa. zvinokonzerwa nekugaya.Mushure mekukunguruka, kuderedzwa kwehukukutu hwepamusoro kunogona kuvandudza chivakwa chakakodzera.
Rolling machining imhando ye chip yemahara machining.Pakupisa kwakajairika, iyo yepurasitiki deformation yesimbi inoshandiswa kudzikamisa iyo microscopic roughness ye workpiece pamusoro kuti uwane chinangwa chekushandura chimiro chepamusoro, hunhu hwemakinika, chimiro uye saizi.Nokudaro, nzira iyi inogona kuzadzisa zvinangwa zviviri zvekutsvaira nekusimbisa panguva imwe chete, iyo isingakwanisi kuita kugaya.
Hazvina mhosva kuti imhando ipi yenzira yekugadzirisa inoshandiswa kugadzirisa, pachagara paine yakanaka convex uye concave mapanga asina kuenzana mamaki pamusoro pezvikamu, uye chiitiko chepamusoro akadzedzereka nemipata,
Rolling processing musimboti: Imhando yekumanikidza kupedzisa kugadzirisa, iko kushandiswa kwesimbi mune yakajairwa tembiricha mamiriro ekutonhora epurasitiki maitiro, kushandiswa kwematurusi ekutenderedza kuita imwe kumanikidza pane workpiece pamusoro, kuitira kuti workpiece pamusoro pesimbi plastiki. yerera, zadza mune yekutanga yasara yakaderera concave dhiri, uye zadzisa iyo workpiece pamusoro roughness kukosha kwakaderedzwa.Nekuda kwekushanduka kwepurasitiki yesimbi yakakungurutswa, ganda repamusoro rinotonhora kuoma uye kuonda kwezviyo, kuumbwa kwedense fiber, uye kuumbwa kweyakasara yekushushikana dhizaini, kuomarara uye simba, nekudaro kuvandudza kupfeka kuramba, corrosion kuramba uye kuenderana kweiyo. workpiece pamusoro.Rolling ipurasitiki machining nzira pasina kucheka.
Quilted seamless pombi akawanda mabhenefiti:
1, kunatsiridza kushata kwepamusoro, roughness inogona kusvika paRa≤0.08µ m kana zvakadaro.
2, kutenderera kwakaringana, ellipcity inogona kuva isingasviki 0.01mm.
3, kunatsiridza kuoma kwepasi, simba deformation rinobviswa, kuoma kunowedzera HV≥4 °
4, mushure mekugadzirisa zvakasara zvekushushikana, gadzirisa simba rekuneta ne30%.
5, kunatsiridza mhando yekukodzera, kuderedza kupfeka, kurebesa hupenyu hwesevhisi yezvikamu, asi mutengo wekugadzirisa wezvikamu wakaderedzwa.
