Chitoliro chopanda msoko ndi mtundu wapamwamba kwambiri wazitsulo zachitsulo pambuyo pojambula kuzizira kapena kugudubuza kotentha.Chifukwa palibe wosanjikiza okusayidi pa mkati ndi kunja makoma a mwatsatanetsatane zitsulo chitoliro, [1] pansi kuthamanga kwambiri popanda kutayikira, mwatsatanetsatane mkulu, mkulu mapeto, ozizira kupinda popanda deformation, flaring, flattening popanda ming'alu ndi zina zotero, makamaka ntchito. popanga zida za pneumatic kapena hydraulic, monga masilindala kapena masilindala, omwe amatha kukhala opanda msoko.The chemical composition of quilted seamless chubu ndi carbon C, silicon Si, manganese Mn, sulfure S, phosphorous P, chromium Cr.
Quilted opanda chitoliro utenga processing luso
Chitoliro chopanda msoko chimakonzedwa ndikugudubuza.Chifukwa cha kupsinjika kotsalira komwe kumakhala pamtunda, ndizothandiza kutseka ming'alu yaying'ono pamtunda ndikuletsa kukokoloka kwa nthaka.Iwo akhoza kusintha kukana dzimbiri pamwamba ndi kuchedwa m'badwo kapena kukula kwa ming'alu kutopa, kuti patsogolo kutopa mphamvu ya quilted zitsulo chitoliro.Ndi kugubuduza kupanga, ozizira ntchito kuumitsa wosanjikiza aumbike pa kugudubuzika pamwamba, amene amachepetsa zotanuka ndi mapindikidwe pulasitiki wa kukhudzana pamwamba pa akupera awiri, motero kuwongolera kuvala kukana kwa khoma lamkati la quilted zitsulo chitoliro ndi kupewa kuwotcha. chifukwa cha kugaya.Pambuyo pakugubuduza, kuchepetsedwa kwa roughness pamwamba kumatha kukonza malo oyenera.
Rolling Machining ndi mtundu wa makina opanda chip.Pa kutentha wabwinobwino, mapindikidwe apulasitiki achitsulo amagwiritsidwa ntchito kufooketsa kuyaka kwapang'onopang'ono kwa workpiece pamwamba kuti akwaniritse cholinga chosinthira mawonekedwe, mawonekedwe amakina, mawonekedwe ndi kukula kwake.Choncho, njirayi ikhoza kukwaniritsa zolinga ziwiri zopukuta ndi kulimbitsa nthawi imodzi, zomwe sizingathe kuchita kugaya.
Ziribe kanthu kuti ndi mtundu wanji wa njira yopangira yomwe imagwiritsidwa ntchito pokonza, nthawi zonse padzakhala zizindikiro za mipeni zowoneka bwino komanso zowoneka bwino pamwamba pazigawo, komanso zochitika za nsonga ndi zigwa,
Kugubuduza processing mfundo: Ndi mtundu wa kuthamanga kutsirizitsa processing, ndi ntchito zitsulo mu yachibadwa kutentha boma ozizira pulasitiki makhalidwe, kugwiritsa ntchito zida anagubuduza kusonyeza kukakamiza ena pa workpiece pamwamba, kuti workpiece pamwamba zitsulo pulasitiki. yendani, lembani mumsewu wotsalira wotsalira wocheperako, ndikukwaniritsa makulidwe amtundu wa workpiece achepetsedwa.Chifukwa mapindikidwe pulasitiki wa adagulung'undisa pamwamba zitsulo, pamwamba minofu kuzizira kuumitsa ndi kupatulira mbewu, mapangidwe wandiweyani CHIKWANGWANI, ndi mapangidwe otsala maganizo wosanjikiza, kuuma ndi mphamvu, motero kuwongolera avale kukana, kukana dzimbiri ndi ngakhale wa workpiece pamwamba.Kugudubuza ndi njira yopangira pulasitiki popanda kudula.
Chitoliro chopanda msoko chili ndi ubwino wambiri:
1, onjezerani roughness pamwamba, roughness akhoza kwenikweni kufika Ra≤0.08µ m kapena choncho.
2, kuzungulira kolondola, elliptical akhoza kukhala osachepera 0.01mm.
3, sinthani kuuma kwapamwamba, kusinthika kwamphamvu kumachotsedwa, kuuma kumawonjezera HV≥4 °
4, mutatha kukonza zosanjikiza zotsalira, onjezerani mphamvu ya kutopa ndi 30%.
5, sinthani mtundu wa zoyenera, kuchepetsa kuvala, kutalikitsa moyo wautumiki wa magawo, koma mtengo wokonza magawo wachepetsedwa.
