Ndedzipi moto ina dzeindasitiri?

1. Kuwedzera

Nzira yekushandisa: Mushure mekupisa simbi kusvika kuAc3+30 ~ 50 madhigirii kana Ac1+30 ~ 50 madhigirii kana tembiricha iri pazasi peAc1 (ruzivo rwakakodzera runogona kubvunzwa), inowanzotonhodzwa zvishoma nezvishoma nehuto rechoto.

Chinangwa:

1. Deredza kuoma, kunatsiridza plastiki, uye kunatsiridza kucheka uye kudzvanywa kwekuita basa;

2. Natsa zviyo, gadzirisa zvinhu zvemakanika, uye gadzirira nzira inotevera;

3. Bvisa kushushikana kwemukati kunokonzerwa nekutonhora uye kupisa kushandiswa.

Maonero ekushandisa:

1. Inokodzera alloy structural simbi, carbon tool steel, alloy tool simbi, high-speed steel forgings, welded parts uye zvisingakodzeri zvinhu zvakasvibirira;

2. Kazhinji, annealing inoitwa mumamiriro ezvinhu akaoma.

2. Kugadzirisa

Nzira yekushandisa: Pisa simbi kusvika 30 ~ 50 madhigirii pamusoro peAc3 kana Accm, uye itonhodze pamwero wekutonhodza wakakura zvishoma pane wekuvharisa mushure mekuchengetedza kupisa.

Chinangwa:

1. Deredza kuoma, kunatsiridza plastiki, uye kunatsiridza kucheka uye kudzvanywa kwekuita basa;

2. Natsa zviyo, gadzirisa zvinhu zvemakanika, uye gadzirira nzira inotevera;

3. Bvisa kushushikana kwemukati kunokonzerwa nekutonhora uye kupisa kushandiswa.

Maonero ekushandisa:

Normalizing inowanzo shandiswa se pre-heat kurapwa maitiro e forgings, weldments uye carburized zvikamu. Kune yakaderera-kabhoni uye yepakati-kabhoni kabhoni structural simbi uye yakaderera-alloy simbi zvikamu zvine yakaderera kuita zvinodiwa, inogona zvakare kushandiswa seyekupedzisira kupisa kurapwa. Kune akajairwa epakati uye akakwira alloy simbi, kutonhora kwemhepo kunogona kutungamira mukudzima kana chidimbu, saka haigone kushandiswa seyekupedzisira kupisa kupisa maitiro.

3. Kudzima

Maitiro ekushandisa: kupisa simbi kusvika pamusoro pechikamu chekuchinja tembiricha Ac3 kana Ac1, ichengetedze kwenguva yakati rebei, wobva waitonhodza nekukurumidza mumvura, nitrate, oiri, kana mhepo.

Chinangwa: Kudzima kazhinji kuwana yakakwira-yakaomarara martensite chimiro, uye dzimwe nguva pakudzima mamwe masimbi alloy (senge simbi isina simbi uye kupfeka-inomira simbi), ndiko kuwana imwechete yunifomu austenite chimiro chekuvandudza kusakara. uye kusagadzikana kwemarara.

Maonero ekushandisa:

1. Kazhinji inoshandiswa ku carbon steel uye alloy simbi ine carbon content yakakura kudarika 0.3%; 2. Kudzima kunogona kupa kutamba kwakazara kune simba uye kupfeka kupikisa kukwanisa kwesimbi, asi panguva imwechete kunokonzera kushushikana kukuru kwemukati uye kuderedza simba resimbi. Plastiki uye kuomarara kwemaitiro, saka kudzikisira kunodiwa kuti uwane zvirinani zvakakwana zvemichina.

4. Kutsamwa

Operation method:

Zvikamu zvesimbi zvakadzimwa zvinopiswa zvakare kune tembiricha iri pasi peAc1, uye mushure mekuchengetedza kupisa, zvinotonhodzwa mumhepo kana mafuta, mvura inopisa, uye mvura.

Chinangwa:

1. Deredza kana kubvisa kushushikana kwemukati mushure mekudzima, kuderedza deformation uye kuputika kwe workpiece;

2. Gadzirisa kuoma, kuvandudza plastiki uye kuoma, uye kuwana michina inodiwa nebasa;

3. Yakagadzikana workpiece saizi.

Maonero ekushandisa:

1. Shandisa yakaderera tembiricha tempering kuti uchengetedze kuomarara kwepamusoro uye kupfeka kusagadzikana kwesimbi mushure mekudzima; shandisa yepakati tembiricha tempering kuvandudza elasticity uye goho simba resimbi uchichengeta kumwe kuoma; kuchengetedza yakanyanya kusimba kusimba uye plastiki Kunyanya, kana paine simba rakakwana, kupisa kwakanyanya kunoshandiswa;

2. Kazhinji, simbi inofanira kuderedzwa pa 230 ~ 280 madhigirii uye simbi isina tsvina inofanira kuderedzwa pa 400 ~ 450 degrees, nokuti kutsamwa kwehasha kuchaitika panguva ino.
