Momwe mungakonzere kuwonongeka kwa mphira extruder screw ndi mbiya

Kukonza mphira extruder screw

1. Chopotoka chopotoka chiyenera kuganiziridwa molingana ndi kukula kwake kwamkati kwa mbiya, ndipo kupatuka kwakunja kwa wononga kwatsopano kuyenera kuperekedwa molingana ndi chilolezo chovomerezeka ndi mbiya.

2. Pambuyo pa ulusi wokhala ndi m'mimba mwake wochepetsetsa wa wononga zowonongeka, alloy yosagwira ntchito imatayidwa ndi thermally sprayed, ndiyeno pansi mpaka kukula.Njira imeneyi nthawi zambiri imakonzedwa ndi kukonzedwa ndi akatswiri opopera mankhwala, ndipo mtengo wake ndi wochepa.

3. Wowotcherera wokutira wosakanikirana ndi ulusi wovunda.Malinga ndi kuchuluka kwa zomangira zomangira, kuwotcherera pamwamba ndi 1 ~ 2mm wokhuthala, ndiyeno wononga ndikusinthidwa mpaka kukula.Aloyi osamva kuvalawa amapangidwa ndi zinthu monga C, Cr, Vi, Co, W ndi B, zomwe zimawonjezera kukana kwa zomangira komanso kukana kwa dzimbiri.Zomera zoyang'ana akatswiri zimakhala ndi mtengo wokwera pakukonza kwamtunduwu, ndipo nthawi zambiri sagwiritsidwa ntchito kawirikawiri kupatula zofunikira zapadera za zomangira.

4. Kuyika kwa chrome kolimba kungagwiritsidwenso ntchito kukonza wononga.Chromium imakhalanso chitsulo chosavala komanso chopanda dzimbiri, koma chitsulo cholimba cha chrome chimakhala chosavuta kugwa.

Kukonza mbiya ya rabara ya extruder

Kulimba kwamkati kwa mbiya ndikwapamwamba kuposa kwa screw, ndipo kuwonongeka kwake kumakhala mochedwa kuposa screw.Kuphulika kwa mbiya ndikuwonjezeka kwapakati mkati chifukwa cha kuwonongeka ndi kung'ambika pakapita nthawi.Umu ndi momwe mungakonzere:

1. Ngati kukula kwa mbiya kumawonjezeka chifukwa cha kuvala, ngati pali gawo lina la nitriding, dzenje lamkati la mbiya likhoza kukhala lotopetsa, pansi mpaka m'mimba mwake, ndiyeno phula latsopano likhoza kukonzekera molingana ndi izi. awiri.

2. M'mimba mwake mkati mwa mbiya imapangidwa ndikukonzedwa kuti ipangitsenso aloyi, makulidwe ake ndi pakati pa 1 ~ 2mm, ndiyeno kumaliza mpaka kukula.

3. Muzochitika zachilendo, gawo la homogenization la mbiya limavala mofulumira.Gawo ili (5 ~ 7D kutalika) likhoza kukonzedwa ndi kunyowa, ndiyeno likhale ndi nitrided alloy steel bushing.The awiri a dzenje lamkati amatanthauza awiri a wononga.Chilolezo choyenera chimakonzedwa ndikukonzedwa.

Apa zikugogomezera kuti mbali ziwiri zofunika za screw ndi mbiya, imodzi ndi ndodo yowonda, ndipo ina ndi dzenje lokhala ndi mainchesi ochepa komanso aatali.Njira zawo zopangira makina ndi kutentha zimakhala zovuta kwambiri, ndipo n'zovuta kutsimikizira zolondola..Choncho, ngati kukonzanso kapena kukonzanso zigawo zatsopano pambuyo pa kuvala kwa zigawo ziwirizi ziyenera kufufuzidwa mozama kuchokera pamalingaliro a zachuma.Ngati mtengo wokonza ndi wotsika kuposa mtengo wosinthira screw yatsopano, ndiye kuti akonza.Izi sizikutanthauza kusankha koyenera.Kuyerekeza pakati pa mtengo wokonzanso ndi mtengo wosinthira ndi gawo limodzi lokha.Kuonjezera apo, zimatengera chiŵerengero cha mtengo wokonza ndi nthawi yogwiritsira ntchito wononga pambuyo pa kukonzanso kwa mtengo wolowa m'malo ndi nthawi yogwiritsira ntchito screw screw.Ndizopanda ndalama kutengera chiwembu chokhala ndi chiŵerengero chaching'ono, chomwe chiri chisankho choyenera.

4. Zida zopangira screw ndi mbiya

Kupanga zomangira ndi migolo.Pakadali pano, zida zomwe zimagwiritsidwa ntchito kwambiri ku China ndi 45, 40Cr ndi 38CrMoAlA.
