Vamwe vanhu vanobatanidzwa mune mamwe mabasa (somuenzaniso, vadzidzisi vemapurisa, vatashanyi) vanoteerera zvakanyanya kusarudzwa kwechimbo chakaita sevha. Sirasi, iyo inobva yaitwa, inopesana mumigero yayo, zvimwe zvinhu zvinoumba zvakagadzirwa, udzvinyiriri. Nokudaro, vazhinji vanofarira mubvunzo uyu: rudzi rwehuni huri nani kune banga?
Mifananidzo yesimbi kune mapanga
Unhu hwemapanga hunobatanidzwa zvakananga nemasikirwo ayo anotevera:
- Uoma hwesimbi kune mapanga . Inogona kutumidzwa sekukwanisa kwechirairo kuti idzivirire kusagadzikana kana kuvhara, iyo inogona kuitika kuva chinhu chakaoma. Sezvo mutemo, magetsi ane banga rakaoma 40-60 HRC. Ndiyo inonyanya kusarudzwa kusarudza banga iro richava neukuoma mukati me 50-60 HRC.
- Simba resimbi - iyi izwi rinoratidza muganhu, kupfuura iyo inotungamirira kukunyengedza kana kunyange kuparadzwa kwekasi. Kubva pane pfungwa iyi, maitiro evha, zvakadai seductility uye brittleness, zvinotarirwawo. Chinyorwa chepurasitiki chingave chinokanganisa kuchinja, kuchinja chimiro chayo, asi kwete kuputsa. Izvo zvinhu zvisingabatsiri zvichaparara kunyange nechinetso chiduku.
- Kupfeka kushorwa kwesimbi . Iko kukwanisa kuchengeta chimiro chesimbe chinoratidzirwa kupesana. Kupfeka kupikisa kunobatana zvakananga nekuoma kwesimbi. Izvo zvakanyanya zvakaoma banga.
Ndeipi midziyo ine nani kutenga banga?
Sirasi ine simbi uye kabhoni, iyo inogona kuva mune yakakwirira, iri pakati kana iri pasi. Mukuwedzera, kuumbwa kwayo kunogona kusanganisira mamwe makemikari anokwanisa - anogona kuva chromium, molybdenum, vanadium, nickel, manganese, silicon.
Kuti usarudze kuti ndeipi yepamusoro yekutenga banga, zvakakosha kuti udzidze maitiro awo pachavo.
Mipanga yakawanda inogadzirwa kubva mucheka. Iine zvinhu izvi:
- zvakanaka kushanduka;
- kukonzera simba;
- high hardness;
- kuvapo kwezvinhu zvakadai zvemakemikari zvakadai semanganese, chromium, silicon, nickel.
Kukanganisa kwemashoko acho kunosanganisira tsika yakakwirira yekurosiro.
Miti kubva kumatambo emvura inogona kunzi universal: pakati pavo kune kicheni, uye vatasvi , uye mauto.
Iyo inonyanya kuzivikanwa ndeyesimbi ye laminated yemapanga. Kazhinji, jasi rakadaro rakasungirirwa nechepakati, nekuda kwekugadzirwa kwakaoma kwakanyanya-carbon carbon inoshandiswa, uye kubatana kwepamusoro-soro kwesimbi yakasiyana-siyana, yakawanda.
Sirasi makirasi emapanga
Matanho emadzivha emadziro anonyanya kuonekwa nekuvapo kwe chromium mavari. Inowedzerwa kuitira kuti kuwedzerwa kushorwa kweakrosiro alloy, banga harivharidzirwa neguru. Asi panguva imwecheteyo, chromium inowanikwa mukuderedza simba resimbi, saka inowanikwa mune zvimwe zviyero.
Zvipfeko zvakanyanya zvakanyanya zvesimbi zvakashandurwa kudivi rinotevera rakagadzirwa mumapoka matatu:
- Mazaya emakumbo, ayo anonyanya kurwisa kupisa, anozivikanwa nekunaka kupfeka kushorwa - anosanganisira AUS6, 7Cr17MoV, 65x3, Sandvik 12C27.
- Mazai emagetsi akaumbwa nesimbi, ayo ane kukwirira kwakasimba nekugara kwenguva refu - aya ndiwo mazita AUS8, 440B, 95x18, Sandvik 19C27, Sandvik 13C26.
- Mabhesi anozivikanwa nekudzivirira kwakanaka kurora uye chikuru pane ose mapanga anoshaya-anosanganisira grade grade 154CM / ATS-34, VG-10, AUS10, 440C.
Sezvo wakadzidza imwe nzvimbo yesimbi kune mapanga, iwe unogona kuzvisarudzira iwe zvakanakisisa kwauri.
