Kuwedzera kukweshera pakati pecrusher roller nerasara danda uye kuwedzera kona yeshaya inopwanya kunogona kuita kuti bhora rakasara riine dhayamita rakakura kupinda nekupwanya.Nokudaro, mazhenje emoto ane hupamhi hwe 30 mm uye urefu hwemamirimita gumi anoputirwa pazvikamu zve 100 mm pamusoro pechiedza chechiedza.Mushure mokunge masara akasara achipinda muimba yekupwanya, inochekwa pasi pechiito chezino rezino, uye kona yejaya rinopwanya rinowedzerwa, uye chiyero chezviyo chinogona kuwanikwa.Iyo dhayamita (6070mm) yakakura uye danda rakasara rakatyoka.
Iyo welding roller surface inogadzirwa nemanual arc welding, uye pamusoro pekaviri-roller crusher iri pamusoro.Pfungwa huru dzekutarisa ndedzinotevera.
(1) D-65, D-667 uye 506 welding tsvimbo dzinosarudzwa.Usati waputira, maererano nemirayiridzo yekugadzira tsvimbo, matanda emoto anoomeswa uye anoiswa muincubator kuti ashandiswe.
(2) Chenesa iyo yekuneta layer yeroller pamusoro, ichenese nekabhoni arc gouging, uye ronga kuneta layer yeroller pamusoro kuratidza roller kune base base material layer.
(3) Shandisa DC welding muchina, iyo inofanirwa kudzoserwa kumashure (welding tsvimbo yakabatana kune yakanaka electrode).Kana yakatarisana, iyo AC welding muchina inoda isina-kuremerwa voltage ye70V, uye iripo inodzorwa inosvika 200A.Kana iyo isina-mutoro voltage yakaderera kupfuura 70V, ikozvino inofanira kuwedzerwa, iyo inobva pane yakazara fusion ye electrode uye nheyo yesimbi.Chiyero chehupamhi hweweld bead kusvika pakukwirira zviri nani 31.
4Zvadaro zvakaenzanirana weld akati wandei akaturikidzana D-667 (yakakwirira-chromium cast iron surfacing tsvimbo inogona kushingirira yakakwira kukanganiswa uye kusagadzika kusagadzikana, kuomarara HRC48 mushure mekunama, kunaka kupfeka kusaga, kusaita ngura uye cavitation kuramba pazasi 500 tembiricha) Panofanira kunge paine ukobvu.Mushure mekunge D-667 weld layer yasvika, mutsetse weD-65 (high-alloy surfacing rod Cr-Si-Mo-B high-corrosion cast-iron wear-resistant surface wear-resistant electrode inogona kumira. Kudzivirira kune yakasimba abrasive kupfeka, zvakanakira iyi electrode yakanaka pamusoro pepamusoro, hapana slag mushure mewelding, yakakwira kupfeka kusagadzikana. Kuomarara mushure mekugadzira HRC60. Kuvandudza mararamiro ehupfeko ka310), ukobvu hwepamusoro i35mm.Pfeka dhizaini Kushushikana kwehukobvu kwakafanana kuitira kuti roller yekusvina irambe yakatenderera panguva yekushandisa.
3 Mhedziso
Kuburikidza nemaitiro ekugadzira, avhareji saizi yeasara electrode yecrusher inowedzerwa kubva pa40mm kusvika 60mm panguva yekugadzira, iyo inoderedza kugadzirwa kwemidziyo yekumusoro, inovandudza kuchinjika kune roller crusher, uye hupenyu hwesevhisi. iyo roller crusher inosvika 10 Mumwedzi, iyo yakaputsika yakasara danda yakasvika 50,000 matani.
