Nhanho inonyanya kukosha mukugadzirwa kwepamusoro-simba mabhoti

Iwo epamusoro-simba bolt mamakisi anogadzirwa nefekitari yedu anosanganisira metric 8.8, 10.9, 12.9, ASTM chiyero.UNC Gr5, 8 mamakisi. Nzungu dzakasimba kwazvo dzinosanganisira metric 8 uye 10 mamakisi, uye ANSI yakajairwa giredhi 5 neG8, izvo zvese zvinoda kurapwa kupisa.

Kudzima uye kupisa kunoreva nzira yekurapa yekupisa inoshandiswa kuvandudza yakazara ma mechanic zvinhu zvesimbi zvinhu. Mushure mekudzima, inoiswa pasi pekupisa kwekupisa kwakanyanya. Chinangwa ndechokuwana kusanganiswa kwakanaka kwesimba uye kusimba muzvikamu zvesimbi, pamwe chete nesimba guru uye kusimba kwakanakisisa, plastiki, kucheka kushanda, etc. Mamwe masimbi alloy kana pasi-alloy steels anofanirwa kudzima uye kupisa kuti awane zvinhu zvakanaka zvakakwana, uye simbi idzi dzinogonawo kunzi dzakadzimwa uye dzakadzikama simbi. Mushure mekudzima uye kupisa kurapwa, ductile iron haingogone kuvandudza simba chete, asiwo inowedzera kuoma uye kupfeka kuramba.

sumo pfupi
Kudzima uye kudziya kurapwa kunoreva nzira mbiri dzekupisa kupisa kwekudzima uye kudziya kwepamusoro-tembiricha, iyo inovavarira kuita kuti workpiece ive yakanaka yakakwana yemagetsi zvivakwa. Kupisa kwakanyanya kunoreva kupisa pakati pe500-650 ℃. Zvikamu zvakadzimwa uye zvakadzimirwa zvinoshanda pasi pemitoro mikuru ine simba, inotakura mhedzisiro yekunetsana, kumanikidzana, kukotama, torsion, kana kugera. Dzimwe nzvimbo dzinewo kukweshana, kunoda kumwe kusamira kwekupfeka, zvichingodaro. Muchidimbu, zvikamu zvinoshanda pasi pekunetseka kwakasiyana kwakaumbwa. Aya marudzi ezvikamu anonyanya kuumbwa zvikamu zvemichina yakasiyana-siyana uye michina, yakadai semashaft, tsvimbo dzekubatanidza, mabhaudhi, magiya, nezvimwewo. Anoshandiswa zvakanyanya mumaindasitiri ekugadzira akadai semichina yekushandisa, mota, uye matirakita. Kunyanya kuzvinhu zvakakura mukugadzira michina inorema, kudzima uye kupisa kurapwa kunonyanya kushandiswa. Nokudaro, kupisa kurapa kunobata basa rinokosha zvikuru mukupisa kupisa. Izvo zvinodikanwa zvekuita zvezvikamu zvakadzimwa uye zvakadzikama mune zvigadzirwa zvemakanika zvinosiyana zvichienderana nemamiriro avo ekushushikana. Kazhinji, zvikamu zvakasiyana-siyana zvinodzimwa uye zvakadzikama zvinofanirwa kuve neakanakisa akazara mekiniki zvivakwa, ndiko kuti, musanganiswa wakakodzera wekusimba kwepamusoro uye kusimba kwepamusoro, kuve nechokwadi chekushanda kwenguva refu kwezvikamu.
Matanho nenheyo
Kudzima ndiyo danho rekutanga, uye tembiricha yekudziya inoenderana nekuumbwa kwesimbi. Iyo yekudzima svikiro inosarudzwa zvichienderana nekuoma kwekugona kwesimbi uye ukuru hwechikamu chesimbi. Mushure mekudzima, simbi ine kushushikana kwakanyanya kwemukati uye yakanyanya brittle. Kudzikamisa kunodiwa kubvisa kushushikana, kuwedzera kuomarara, uye kugadzirisa simba. Kudzikamisa ndiyo inonyanya kukosha maitiro ekumisikidza ma mechanic zvivakwa zvesimbi yakadzimwa uye yakapfava. Iyo curve yeakasiyana simbi mechanicha zvivakwa zvinochinja nekupisa tembiricha, inozivikanwawo seyekupisa curve yesimbi, inogona kushandiswa sehwaro hwekusarudza tembiricha yekupisa. Nokuda kwekupisa kwekupisa kweimwe alloy yakadzimwa uye yakasvibiswa simbi, kutarisisa kunofanira kubhadharwa kudzivirira kuitika kwechipiri rudzi rwekupisa brittleness kuti ive nechokwadi chekushanda kwesimbi.
application
Kudzimisa uye kudziya kurapwa kunoshandiswa zvakanyanya kune zvikamu zvemugadziriso zvinoda kukwenenzverwa kwekuita, kunyanya pakushanda pasi pemitoro inochinjana, senge mashaft emotokari uye magiya, turbine shafts uye compressor discs einjini dzendege, nezvimwewo. Masimbi esimbi anoda induction heat quenching anowanzo kudzimwa uye kudzikamiswa pamberi peiyo yunifomu inodzika uye kudzikamisa yunifomu. layer uye inogona zvakare kuwana yakanaka yakazara mekinika zvivakwa mupakati. Zvikamu zveNitrided zvinodzimirwa uye kurapwa kwekupisa pamberi penitriding zvinogona kuvandudza mashandiro esimbi uye kugadzirira chimiro che nitriding. Kuti uwane kutsetseka kwepamusoro kwechiyereso chekuyeresa usati wadzima, bvisa kushushikana kunokonzerwa nehutsinye machining, kuderedza kudzima deformation, uye kuita kuomarara mushure mekudzima yakakwirira uye yunifomu, kudzima uye kupisa kurapwa kunogona kuitwa kusati kwaitwa machining. Kune masimbi emidziyo ane network carbides kana coarse zviyo mushure mekugadzira, kudzima uye kupisa kurapwa kunogona kushandiswa kubvisa iyo carbide network, kunatsa zviyo, uye kugadzirisa machinability ne spheroidizing the carbides, kugadzirira iyo microstructure yekupedzisira kupisa kurapwa.
Processing tekinoroji
Iyo yekupisa yekurapa maitiro esimbi inosanganisira nzira dzakadai seannealing, normalizing, quenching, tempering, uye pamusoro kupisa kurapwa. Pakati pavo, kupisa kunosanganisira kupisa-kupisa, kutonhora kwepakati, uye
Kudzika kwekushisa. Kudziisazve simbi yakadzimwa kune imwe tembiricha wozoitonhodza uchishandisa imwe nzira inonzi tempering. Chinangwa ndechekubvisa kushushikana kwemukati kunokonzerwa nekudzima, kuderedza kuoma uye brittleness, uye kuzadzisa zvinotarisirwa.

mechanical properties.
Kudzima uye kupisa kazhinji kunoreva nzira yekupisa yekudzima uye kudziya kwepamusoro-tembiricha kuwana martensite. Iyo nzira ndeyekutanga kudzima, ine tembiricha yekudzima yeAc3 + 30-50 ℃ ye hypoeutectoid simbi; Eutectoid simbi ndeye Ac1+30 ~ 50 ℃; Alloy simbi inogona kuvandudza zvishoma kana ichienzaniswa nekabhoni simbi. Mushure mekudzima, kupisa kunogona kuitwa pa500-650 ℃.
Simbi dzakadzimwa uye dzakapfava
Iyo inonzi quenched uye tempered simbi inowanzoreva yepakati kabhoni simbi ine kabhoni inokwana 0.3-0.6%. Zvikamu zvinogadzirwa nemhando iyi yesimbi zvinowanzoda yakanaka yakazara mekiniki zvivakwa, kureva, kuchengetedza simba repamusoro ukuwo uine yakanaka plastiki uye kuoma. Vanhu vanowanzo shandisa modulation kurapwa kuti vazadzise chinangwa ichi, saka vanhu vanogara vachitaura nezverudzi urwu rwesimbi sesimbi inodzimwa uye yakapfava. Izvo zvinofanirwa kucherechedzwa kuti dzimwe nguva kudzima uye kudziya simbi inorevawo maitiro ekuwedzera manganese nesilicon panguva yekunyungudutswa kwesimbi, uye kutarisisa kunofanirwa kubhadharwa kune musiyano.
