Litšepe tse pota-potiloeng tse chesang tsa CrWMn

CrWMn die steel plate ke motsoako oa tšepe ea tšepe, oli e timang deformation e tlase e batang e sebetsang ea tšepe. The wearability ea tšepe, ka lebaka la ho ikopanya le karoloana e boima ea 1.20% ~ 1.60% ea tungsten, e etsa carbides ka mor'a ho tima le mocheso o tlase ho ba le boima le boima ba 'mele. Abrasion resistance.Tungsten e thusa ho thibela mabele a matle hore a se ke a etsa tšepe haholoanyane.Tšepe e na le kutloelo-bohloko ha e etsa k'habone, e leng se ka etsang hore lehare le tsitse.Le hoja matla, thata le ho thatafala ha tšepe li phahametse tsa carbon steel, e na le mefokolo joalo ka ho peperana ha bonolo le ho sila ka lebaka la karohano ea carbide. Ho tima ho na le tšepe ea carbon, 'me mefuta ea ts'ebeliso ea fokotseha.Ho thatafala ha tšepe le ho sila ha tšepe hammoho le ho thatafala ha tšepe ea chromium le tšepe ea chromium silicon ka morao. ho tima ho molemo, 'me ho thata ho molemo.
CrWMn haholo-holo e sebelisoang bakeng sa tšepe ea tšepe ea carbon e ke ke ea finyella litlhoko tsa karolo e kholo ea sefapano, sebopeho se rarahaneng sa likarolo tsa lefu, se hloka deformation e fokolang ea ho tima.
1) Mofuta ona oa tšepe o sebelisoa haholo ha ho sebetsoa tšepe e tšesaane, tšepe e se nang ferrous, lisebelisoa tsa motheo tsa mojaro o bobebe le sebopeho se rarahaneng, haholo-holo masimong a oache, sesebelisoa, papali le indasteri ea lihlahisoa, joalo-joalo. Letlapa la tšepe la hedging austenite, lakane ea tšepe ea silicon le poleiti ea tšepe e matla haholo ha e lokele.

2) botenya ba tšepe bo ka sebelisoa ho etsa thepa <1 mm ea sekoahelo se entsoeng ka sekontiri se thata, concave die, set piece, le likhoele tse tebileng ⼀ tsa ho taka tse tebileng lia shoa. Tlhahiso ea Punch e khothalelitse 58 ho 62 HRC thata, mme tlhahiso ea hlobo ea concave e khothalelitse hore boima ba 60 ~ 64 HRC.

3) E sebelisoa bakeng sa ho kenngoa ha punch die e nang le khanyetso e phahameng ea ho apara le sebōpeho se rarahaneng ka ho kobeha shoa. Boima ba punch die bo khothaletsoa ho ba 58 ~ 62HRC mme 60-64hrc e khothaletsoa hore e be 60-64hrc ha ho etsoa hore punch e shoe.

4) A convex die and concave die for cold extrusion die of aluminium parts.The hardness of 60 ~ 62HRC e kgothaletswa bakeng sa punch die le 62 ~ 64HRC e kgothaletswa bakeng sa punch die.

5) Bakeng sa li-extrusion tse batang tse shoang ka likarolo tsa koporo le ho shoa ha serame se batang le ho shoa ka likarolo tsa tšepe, boima bo khothalletsoang ke 62-64hrc.

6) Ka mor'a ho etsoa, ​​​​e ka sebelisoa ho etsa liforomo tse kholo tsa veneer tse sebelisoang mechineng ea khatello e fetang 1mm, hangata e eketsa ho thatafala ha tšepe ho 50-55hrc. Leha ho le joalo, mefokolo e hlakileng ea lisele tse kang sebopeho sa carbide kapa chromatography ea metsi e lokela ho fokotsoa kapa ho qojoe.
