Quenching dumama zafin jiki: 950 ± 10 ℃;

Tempering dumama zafin jiki: 650 ± 10 ℃;

4) Input ƙarfin lantarki: 380V ± 10%

5) Bukatar fitarwa: 2T / H (batun 100mm zagaye karfe)

3. Fasaha da buƙatun don kayan aiki quenching da tempering:

1) Ƙaƙƙarfan yanayin gaba ɗaya na dukan shaft shine 22-27 digiri HRC , ƙananan taurin ba zai iya zama ƙasa da digiri 22 ba, kuma taurin da ya dace shine digiri 24-26;

2) A taurin guda shaft dole uniform, taurin wannan tsari, dole kuma uniform, da kuma uniformity na wani shaft dole ne a cikin 2-4 digiri.

3) Dole ne ƙungiyar ta zama uniform kuma kayan aikin injiniya sun cika buƙatun:

a. Ƙarfin amfanin gona ya fi 50kgf/mm ²

b. Ƙarfin ɗamara ya fi 70kgf/mm ²

c. Tsawaitawa ya fi 17%

4) Mafi ƙasƙanci na tsakiyar da’irar ba zai zama ƙasa da HRC18 ba, mafi ƙanƙanci na 1 / 2R ba zai zama ƙasa da digiri na HRC20 ba, kuma mafi ƙasƙanci na 1 / 4R ba zai zama ƙasa da digiri na HRC22 ba.

2. Kayan aiki dalla-dalla

Dangane da bukatun mai siye, muna samar da waɗannan na’urori masu auna firikwensin don 45-150 zagaye karfe.

Dangane da teburin ƙayyadaddun kayan aikin da mai siye ya bayar, ana buƙatar jimlar 4 na inductor, saiti 4 kowanne don quenching da tempering. The dumama kewayon workpiece ne 40-150mm. Firikwensin hauhawar zafin jiki mai kashewa yana ɗaukar ƙirar 800mm × 2, firikwensin zafin jiki mai kashewa yana ɗaukar ƙirar 800mm × 1, kuma inductor adana zafi yana ɗaukar ƙirar 800mm × 1 don tabbatar da dumama iri ɗaya. An tsara ɓangaren zafin jiki a cikin hanya ɗaya.

Uku, bayanin kwararar tsari

Da farko, da hannu sanya kayan aikin da ake buƙatar mai zafi a cikin jere ɗaya da Layer guda ɗaya a kan ma’aunin ajiya na ciyarwa, sa’an nan kuma a hankali a aika da kayan zuwa wurin ciyarwa ta na’ura mai ɗaukar nauyi, sa’an nan kuma an tura kayan a cikin ciyarwa. nadi karkata da iska Silinda. Abin nadi mai ni’ima yana fitar da kayan mashaya gaba kuma ya aika kayan zuwa inductor mai kashe dumama. Sa’an nan workpiece ne mai tsanani da quenching dumama part, da kuma quenching dumama ne zuwa kashi quenching dumama dumama da quenching zafi adana dumama. A cikin quenching da dumama bangaren, ana amfani da wutar lantarki na matsakaicin mita 400Kw don dumama kayan aikin, sa’an nan kuma ana amfani da nau’i biyu na 200Kw matsakaicin wutar lantarki don adana zafi da dumama.

Bayan dumama da aka gama, da workpiece ne kore ta karkata zuwa ga wucewa ta cikin quenching ruwa fesa zobe domin quenching. Bayan quenching da aka kammala, shi shiga tempering dumama inductor ga tempering dumama. Tempering dumama kuma ya kasu kashi biyu: tempering dumama da tempering zafi kiyayewa. Bangaren dumama yana amfani da wutar lantarki mai matsakaicin mita 250Kw, kuma sashin adana zafi yana amfani da saiti biyu na samar da wutar lantarki mai matsakaicin 125Kw. Bayan an gama dumama, an fitar da kayan, kuma ana aiwatar da tsari na gaba.
