Zvishandiso nemidziyo inoshandiswa pakugadzira mahara zviri nyore, zvepasirese uye zvinodhura. Kuenzaniswa nekukanda blank,vakasununguka forginginobvisa shrinkage cavity, shrinkage porosity, porosity uye humwe hurema, kuitira kuti iyo isina chinhu ive nepamusoro michina.Forgingszviri nyore muchimiro uye zvinochinjika mukushanda. Nokudaro, inonyanya kukosha mukugadzirwa kwemichina inorema uye zvikamu zvakakosha.
Nzvimbo yekushandisa
Free forgingszvinodzorwa nekushanda kwemaoko kwechimiro uye saizi yeforgings, sakakugadzira chaikoyakaderera, kubvumidzwa kwekugadzirisa kwakakura, kusimba kwevashandi kwakakura, kubereka hakuna kukwirira, saka inonyanya kushandiswa mune imwechete, diki batch kugadzirwa.
1) Saizi yebillet uye saizi yepakati inofanirwa kuenderana neanoshanda mapoinzi ega ega maitiro, senge kureba-dhayamita reshiyo (H / D) yezvinhu zvisati zvagumburwa ndeye 2-2.5, uye empirical data yekushandurwa kwechikamu pakudhirowa. kunze.
2) zvakakosha kufungidzira shanduko yesaizi isina chinhu mumaitiro ekugadzira,semuenzaniso, kureba kusina chinhu kunoderedzwa kana uchibaya, kazhinji 1.1 nguva dzehurefu hwefogi; Kana iyo core shaft reaming kureba inowedzerwa.
3) chikamu indentation, inofanirwa kuve nechokwadi chekuti chikamu chega chega chekugadzira chine vhoriyamu yakakwana, senge munhanho shaft, crankshaft kana gear boss billet, ita basa rakanaka rekugovera vhoriyamu yechikamu chimwe nechimwe.
4) Riniforgingnemoto wakawanda, kutarisisa kunofanirwa kubhadharwa kune mukana wekudziya moto wega wega pakati. Kana iyoforgingsanodhonzwa akareba kwazvo pakutanga, ukuru hwechoto hahuna kukwana kuti uise mukati mefogi refu panguva yekudziya kwechipiri. Kuti ive nechokwadi chehukuru uye hunhu hwemafogi, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune deformation yemoto mushure meZ uye kutonga kwekushisa kwekutanga uye kwekupedzisira kuumba mushure meZ.
5) Izvo zvinodikanwa kuve nechokwadi kuti kune yakakwana yekuchera mvumo mushure mekupedza mushure meZ, uye kutarisisa kunofanirwa kubhadharwa kune:
(1) Nekuti mukutsikirira pfudzi, kutama, kurova uye zvichingodaro, pane chiitiko chekudhirowa uye kuderera pane isina chinhu, iyo inofanirwa kusiya mvumo yekupfeka iri pakati pekuita;
(2) Kugadzira kwenguva refushaft forgings(zvakadai se crankshafts, nezvimwewo) uyeforgingsne concave blocks, nekuti urefu hwawo hunogona kutsamwiswa zvakare, zvinofanirwa kufungidzirwa kuti saizi yehurefu hwacho huchawedzerwa zvishoma mukupfeka uye kutungamirira kunze-ku-kushivirira.

Forging.
6) Pakusarudza maturusi, vana vanofanirwa kushandisa maturusi ese. Kana iyo batch yekugadzira yakakura, maturusi akakosha kana mold matayi anogona kugadzirwa kuti avandudze mhando uye kubuda kwefogi.
7) Zvinoenderana nehukuru uye kunaka kweiyo isina chinhu, sarudza midziyo iripo muwekishopu.
