Shot blasting izita zvakare remuchina wekurapa pamusoro pemaitiro, akafanana nekuputika kwejecha uye kuputika kwepfuti. Shot blasting inzira inotonhora yekurapa, iyo yakakamurwa kuita pfuti blasting yekuchenesa uye pfuti inoputika kusimbisa. Sezvinoratidzwa nezita racho, kuchenesa kuputika kwepfuti ndiko kubvisa tsvina yakaita sepamusoro oxide kuti uvandudze chitarisiko. Shot blasting kusimbisa ndeye kushandisa high-speed inofamba projectile (60-110m/s) inoyerera kuti irambe ichikanganisa pamusoro peiyo workpiece kuti isimbiswe. Nzvimbo dzepamusoro uye dzepamusoro dzechinangwa (0.10-0.85mm) dzinomanikidzwa kuchinja zvinotevera panguva yekuchinja kwe cyclic: 1. Iyo microstructure yakashandurwa; 2. Iyo isiri-uniform yeplasticized yekunze yekunze inopinza yakasara yekumanikidza kushushikana, uye mukati memukati unoburitsa yakasara tensile kusagadzikana; 3. External surface roughness inoshanduka (RaRz). Mhedzisiro: Inogona kuvandudza kuneta kuputsika kuramba kwemidziyo / zvikamu, kudzivirira kupera simba, deformation yepurasitiki uye brittle fracture, uye kuvandudza kuneta hupenyu.
Nheyo yekupfura blasting process:
Shot blasting zvinoreva kuti pfuti (steel shot) inokandwa kunzvimbo yekushanda nekumhanya kukuru uye imwe Angle by mechanical method, kuitira kuti pfuti pfuti ive nekumhanya kwakanyanya panzvimbo yebasa. Pasi pechiito chakasanganiswa chevacuum cleaner vacuum negative pressure uye rebound simba, zvinhu zvepfuti zvinozvitenderedza mumidziyo. Panguva imwecheteyo, iyo yakapfurwa uye tsvina yakacheneswa pasi inodzoserwa zvakateerana kuburikidza nemhepo yekuchenesa maitiro einotsigira vacuum cleaner. Uye nzira inobvumira kuti pellets irambe ichishandiswazve. Muchina uyu wakashongedzerwa nemuunganidzi weguruva kuti uwane guruva-isina uye kusvibiswa-kusina kuvakwa, izvo zvisingangonatsiridza kushanda zvakanaka asiwo kuchengetedza zvakatipoteredza. Kana muchina wacho uchishandiswa, saizi yepellet uye chimiro chepellet inosarudzwa, uye kumhanya kwekufamba kwemidziyo kunogadziriswa uye kudzorwa kudzora purojekiti yekuyerera kwepellet, kuitira kuti uwane kwakasiyana projectile intensity uye kuwana akasiyana epamusoro kurapwa. effects.
Tekinoroji zvinodiwa zvepfuti blasting process:
Nekudzora nekusarudza saizi yechikamu uye chimiro chepellet, kugadzirisa uye kuseta kukurumidza kwekufamba kwemuchina, kudzora iyo projectile kuyerera kwepellet, akasiyana projectile intensity uye akasiyana epamusoro kurapwa maitiro anogona kuwanikwa. Iyo pfuti yekuputika maitiro uye pfuti inoputika midziyo inodzora mamiriro epamusoro mushure mekurapa kuburikidza nematanho matatu zvichienderana nenzvimbo yakasiyana inofanirwa kurapwa. Sarudza saizi uye chimiro chepellet; Kumhanya kwekufamba kwemidziyo; Kuyerera kwepellet. Iwo matatu ari pamusoro apa ma paramita anoshandira pamwe chete kuti awane akasiyana mhedzisiro yekurapa uye ive shuwa kushata kwepamusoro mushure mekuputika kwepfuti. Semuenzaniso: kushandisa S330 simbi kupfura, kuyerera 10A, kurapwa kweC50 kongiri yepamusoro, inogona kusvika kune roughness ye90; Nokurapa nzvimbo yeasphalt, kuputika kwemafashamo kunogona kubviswa uye roughness ndeye 80. Paunenge uchibata mahwendefa esimbi, chiyero chehutsanana cheSA3 chinogona kusvika.
Shot blasting inzira yekuchenesa, kusimbisa (pfuti blasting) kana kukwenenzvera workpiece nepfuti blasting machine, iyo inoshandiswa munenge maindasitiri ese anoshandisa simbi, kusanganisira aerospace, mota, kuvaka, casting, shipbuilding, railways nemamwe maindasitiri mazhinji. . Pane nzira mbiri: kuputika kwepfuti kana kuputika kwejecha.
Yekutanga: pfuti inoputika muchina:
1. Muchina wekupfurwa unoshandura simba remudhudhudhu rakananga musimba rinopisa simba nekutenderedza turbine impeller.
2, huwandu hweyega yega impeller kubva pa60 kg paminiti kusvika 1200 kg paminiti.
3, kushandisa aya akawanda maaccelerators, shandisa chigayo chevhiri, umo mahombe kana nzvimbo huru dzezvikamu zvinofanirwa kunge zviri mune imwe nzira ye ngura, descaling, deburing, peeling kana kuchenesa.
4, Kazhinji, nzira yekufambisa yezvikamu zvichakandwa ichatsanangura rudzi rwemuchina: kubva pamatafura akareruka kusvika kune akasanganiswa akazara otomatiki manipulators ehuwandu hwakazara hwevagadziri vemotokari, kuburikidza nemaroller conveyors uye bhandi descaling masisitimu.
Chechipiri: jecha rinoputika muchina:
1, muchina wekuputisa jecha unogona kushandiswa muchimiro chekuvhuvhuta kana kuvhuvhuta, iyo mhepo inoputika inokwidziridzwa nemhepo yakamanikidzwa uye inofananidzirwa kune zvikamu nemuromo.
2, yezvishandiso zvakakosha, musanganiswa-mvura musanganiswa unogona kushandiswa, unonzi wet sandblasting.
3, mumhepo uye yakanyorova jecha rinoputika, iyo muromo inogona kuiswa munzvimbo yakagadziriswa, kana inogona kushandiswa nemaoko kana neatomatiki nozzle opareta kana PLC yakarongwa otomatiki system.
4, basa rejecha rinotarisa sarudzo yekukuya midhiya, kazhinji inogona kushandisa chero mhando yakaoma kana yemahara-inomhanya kugaya media.
