Mucheka wekugayo unoshandiswa nei? Kupfeka kweguyo rekucheka panguva yekushandiswa

Munguva yekugaya, chigayo chegayo pachacho chichapfekwa uye chisina kusimba paunenge uchicheka machipisi. Mushure mekunge chigayo chekucheka chakagomara kune imwe nhanho, kana chikaramba chichishandiswa, zvinotungamira kukuwedzera kukuru kwesimba rekugaya uye tembiricha yekucheka, uye huwandu hwekupfeka kweguyo hunowedzerawo nekukurumidza, zvichikanganisa machining. kurongeka uye kunaka kwepamusoro uye chiyero chekushandiswa kwechigayo chekucheka.

Nzvimbo yekupfeka kwezvishandiso inoitika kunyanya kumberi uye kumashure kwekucheka uye kunharaunda kwayo. Kupfeka kwechigayo chekucheka kunonyanya kupfekedzwa kumashure uye kumucheto kweblade.

1. Zvikonzero zvekupfeka zvigayo zvekucheka

Zvikonzero zvikuru zvekupfeka zvigayo zvekucheka zvipfeko zvemuchina uye kupfeka kwekupisa.

1. Mechanical kupfeka: Mechanical wear inonziwo abrasive wear. Nekuda kwematinji akaomesesa ari pamusoro pekukweshana kwemachipisi kana machira ekushanda, senge carbides, oxides, nitrides uye akavakirwa-mupendero zvimedu, groove mamaki ekudzika kwakasiyana anotemerwa pachishandiso, zvichikonzera kupfeka kwemuchina. Iyo yakanyanya kuoma iyo workpiece zvinhu, iyo yakakura kugona kwezvimedu zvakaoma kukwenya pamusoro pechishandiso. Rudzi urwu rwekupfeka rune mhedzisiro iri pachena pane yakakwirira-yekumhanya simbi maturusi. Kuvandudza kunaka kwekukuya kwechigayo chekucheka uye kuderedza kukosha kwekushata kwepamberi, kumashure uye kuchekwa, izvo zvinogona kudzikamisa chiyero chekupfeka kwechigayo chekucheka.

2. Kupfeka kwekushisa: Panguva yekugaya, kutonhora kunokwira nekuda kwechizvarwa chekucheka kupisa. Kuoma kwezvinhu zvekushandisa kunoderedzwa nekuda kwekushanduka kwechikamu kunokonzerwa nekukwira kwekushisa, uye zvinhu zvekushandisa zvinonamatira kune chip uye workpiece uye inotorwa nekunamatira, zvichiita kuti kusungirirwa kupfeka; pasi pechiito chekushisa kwakanyanya, iyo alloy zvinhu zvechishandiso zvinhu uye workpiece zvinhu zvinopararira uye kutsiva mumwe nemumwe. , iyo mechanical properties yechishandiso inoderedzwa, uye kupararira kupfeka kunoitika pasi pechiito chekurwisana. Aya mapfekero ezvigayo anocheka anokonzerwa nekucheka kupisa uye kukwira kwetembiricha akaunganidzwa anonzi seyekupisa.

Chechipiri, nzira yekupfeka yekucheka kwekucheka

Kufanana nemamwe maturusi ekucheka, kupfekwa kwevanocheka kugaya kunokura zvishoma nezvishoma nekuwedzera kwenguva yekucheka. Iyo nzira yekupfeka inogona kukamurwa mumatanho matatu:

1. Danho rekutanga kupfeka: Danho iri rinokurumidza kupera, zvikuru nekuti mapeaks econvex anogadzirwa nemavara ekukuya pamusoro pevhiri rekukuya uye maburr ari pablade anokurumidza kukuyiwa munguva pfupi mushure mekunge chigayo charodzwa. Kana iyo burr yakakomba, huwandu hwekupfeka huchave hwakakura. Vandudza kunaka kwekurodza kwechigayo chekucheka, uye shandisa kugaya kana whetstone kukwenenzvera kuchekwa kwekucheka uye kumberi nekumashure, izvo zvinogona kunyatso kudzikisa huwandu hwekupfeka muchikamu chekutanga chekupfeka.

2. Nhanho yenguva dzose yekupfeka: Muchikamu chino, kupfeka kunenge kunonoka, uye chiyero chekupfeka chinowedzera zvakaenzana uye zvakasimba nekuwedzera kwekucheka nguva.

3. Kukurumidza kupfeka nhanho: Mushure mekunge chigayo chekucheka chashandiswa kwenguva yakareba, blade inogomara, simba rekugaya rinowedzera, tembiricha yekucheka inokwira, mamiriro ekugaya anowedzera kuipa, chiyero chekupfeka chigayo chinowedzera zvakanyanya, chiyero chekupfeka chinowedzera. zvakapinza, uye chishandiso Rapid kurasikirwa kwekucheka kugona. Paunenge uchishandisa chigayo chekucheka, zvinofanirwa kudzivirirwa kuti chigayo chinocheka chinopfeka mune ino nhanho.

3. Muyero wakaoma wekugadzira milling

Mubasa chairo, kana mucheki weguyo aine imwe yeanotevera mamiriro, zvinoreva kuti mucheki weguyo akagomara: kushata kwepamusoro ukoshi hwemakina hwakakura zvakanyanya kupfuura hwepakutanga, uye mavara akajeka uye zviyero zvinoonekwa pamusoro; tembiricha yekucheka yakawedzera zvakanyanya, uye machipisi Muvara unoshanduka; simba rekucheka rinowedzera, uye kunyange kudengenyeka kunoitika; iyo yekumashure iri padhuze nechekacheka iri pachena yakapfekwa, uye kunyangwe ruzha rusina kujairika runoitika. Panguva ino, chigayo chinocheka chinofanirwa kubviswa kuti chirodze, uye kugayo hakugone kuenderera mberi, kuitira kudzivirira kusakara kwakakomba kana kukuvadzwa kweguyo.
