Kuongororwa kwemaitiro ekugadzirisa ruoko uchishandisa yepamusoro-frequency kudzima michina yekurapa kupisa

Mawoko reamers anoshandisa yakakwirira-frequency quenching midziyo yekurapa kupisa. Pane zvinhu zvakawanda zvinokanganisa maitiro ekurapa kupisa, senge maitiro ekupisa uye mbishi. Pakati pezvinhu izvi, nzira yekurapa yekupisa ine simba guru. Naizvozvo, zvinonyanya kudikanwa kugona kupisa kupisa maitiro emaoko reamer.

1. Zvido zvehunyanzvi zvekugadzirisa ruoko:

Izvo zvinowanzo shandiswa zvemaoko reamer ndeye 9SiCr simbi.

Kuoma: 62-64HRC ye φ3-8; 63-65HRC ye φ8.

Bata kuoma: 30-45HRC.

Huwandu hwekukotama kukanganiswa kweiyo ruoko reamer inotemerwa kuve 0.15-0.3mm zvinoenderana nedhayamita uye kureba.

2. Kupisa kurapwa maitiro

Iyo nzira yekupisa yekupisa ndeye: preheating, kudziyisa, kutonhora, kutwasanudza, kupisa, kuchenesa, kuomarara kuongorora, kusviba, uye kutarisisa chitarisiko. Kupisa kunonyanya kuitwa ne-high-frequency quenching midziyo, pakati peiyo preheating tembiricha iri 600-650 ° C, tembiricha yekudziya i850-870 ° C, uye tembiricha inodziya i160 ° C.

Mubati wemaoko unogona kudzimwa zvachose uye wobva wadzvanya shank. The annealing tembiricha i600 ° C, uye wodzimwa mu nitrate munyu pa 150-180 ° C kutonhora kupfuura 30s.

3. Tsanangudzo yemaitiro

(1) Kuti uderedze kukotama kweanobatidza mushure mekudzima, kudzoreredza kwekushushikana kunogona kushandiswa kusati kwadzima.

(2) Kuti uderedze kukanganiswa kweiyo reamer nedhayamita isingasviki 13mm, iyo yakaderera muganho wekudzima tembiricha inogona kutorwa. Kune iyo hinge simba ine dhayamita yakakura kupfuura 13mm, kuitira kuti ivandudze kuomarara kwayo, iyo yepamusoro muganhu wekudzima tembiricha uye kupisa kwemafuta kutonhora kunogona kushandiswa.
