Kuyerera Kwekugadzira
1 Danho: Peeling / Kutonhora Kudhirowa:
Cold kudhirowa igadziriso tekinoroji yepneumatic cylinder piston tsvimbo.Kune pneumatic cylinder hard chrome plated rod, kutonhora kudhirowa kunoreva kudhirowa pasi pemamiriro ekunze tembiricha kuitira kuti uwane imwe chimiro uye mamwe ma mechanic properties.Zvichienzaniswa nekupisa kuumbwa, zvigadzirwa zvinotonhorwa zvinotonhora zvine zvakanakira kurongeka kwepamusoro uye kupera kuri nani kwepamusoro.
2 Danho: Kururamisa
Iyi nhanho tinogona kuita shuwa kuti yakaoma chrome yakapfatwa tsvimbo yakatwasuka zvakakwana.Izvo zvakakosha, kana uchiisa mukati meiyo pneumatic cylinder.Kutwasanuka kuri 0.2mm/m.
3 Danho: Kukudza
Honing processing inzira inoshanda yekugadzira iyo inogonesa iyo pneumatic cylinder piston rod pamusoro kuti iwane yakakwira chaiyo, yepamusoro yepamusoro uye hupenyu hurefu.Inogona kunyatso kuvandudza kurongeka kwedimensional, chimiro chechokwadi uye kuderedza kukosha kweRa, asi haigone kuvandudza nzvimbo yegomba uye mamwe mapeji.
4 Danho: Simbi yekupukuta
Kupukuta kunoreva kushandiswa kwemakanika, kemikari kana electrochemical mhedzisiro kuderedza kushata kwepamusoro kwepneumatic cylinder piston tsvimbo kuti uwane inopenya uye yakatsetseka pamusoro.Iko kushandiswa kwezvishandiso zvekupukuta uye zvimedu zvinoputika kana imwe midhiya yekupukuta kugadzirisa pamusoro peiyo pneumatic cylinder piston tsvimbo.
5 Nhanho: Chrome Plating
Chrome plating inoreva chiitiko chekuputira chromium sejira pane pneumatic hard chrome plated rod.
Iyo chromium-plated layer ine yakanyanya kuoma, uye kuomarara kwayo kunogona kusiyanisa mukati mehupamhi hwe400-1200HV zvichienderana nekuumbwa kweiyo plating mhinduro uye maitiro ekugadzirisa.Iyo chrome-plated layer ine yakanaka yekudzivirira kupisa.Kana ichipisa pasi pe500 ℃, hapana shanduko iri pachena mukupenya uye kuoma.Tembiricha inotanga kuita oxidize uye kuchinja ruvara kana tembiricha iri pamusoro pe500 ℃, uye kuoma kunodzikira kana kuri pamusoro pe700 ℃.Iko friction coefficient ye chrome layer idiki, kunyanya yakaoma friction coefficient, iyo yakaderera pakati pesimbi dzese.Naizvozvo, iyo chrome-plated layer ine yakanaka kupfeka kuramba.
Iyo chromium plating layer ine yakanaka kugadzikana kwemakemikari.Izvo hazvina simba mu alkali, sulfide, nitric acid uye yakawanda organic acids, asi inogona kunyungudutswa mu pneumatic acid (yakadai sepneumatic acid) uye inopisa sulfuric acid.Muchikamu chechiedza chinooneka, kuratidza kwechromium kunenge 65%, iri pakati pesirivha (88%) uye nickel (55%).Nekuti chromium haichinje ruvara, inogona kuchengetedza kutaridzika kwayo kwenguva yakareba uye iri nani pane sirivheri uye nickel.
6 Nhanho: Chrome yakaputirwa tsvimbo Kupenya mushure mekuputirwa
Electroplating uye polishing: inzira mbiri dzakasiyana dzekurapa pamusoro pesimbi uye zvimwe zvinhu.Iyo yekutanga kurapwa kwemakemikari, uye iyo yekupedzisira ndeye mechanical treatment.
Electroplating: Maitiro ekushandisa electrolysis kubatanidza chidimbu chesimbi firimu pamusoro pesimbi kana zvimwe zvinhu.Inogona kudzivirira ngura, kunatsiridza kupfeka kuramba, magetsi conductivity, reflectivity uye kuwedzera aesthetics.
Kupolisha: Shandisa maturusi ekupurudzira anochinjika uye twumabrasive particles kana imwe polishing midhiya kugadzirisa pamusoro peiyo workpiece.Kupenya hakugone kuvandudza kurongeka kwedimensional kana geometric iko kweiyo workpiece, asi ine chinangwa chekuwana yakatsetseka pamusoro kana girazi gloss.
7 Nhanho: Chrome yakaputirwa tsvimbo Yekuyedzwa Kwemhando
Piston tsvimbo dzakaitwa electroplating uye polishing maitiro anowanzo kuperekedzwa nekuremara kwekuputira senge chrome makomba uye gomba.Hukuru uye huwandu hwezvirema izvi zvinokanganisa zvakananga kuita kwepiston tsvimbo.Kudzikisa kukanganisa kwehurema uhu papiston tsvimbo, kune rumwe rutivi, nekuvandudza kunaka kwezvinhu zvakasvibiswa, kuvandudza tekinoroji yekugadzira, uye kuderedza kuitika kwehurema;kune rumwe rutivi, zvinodikanwa kunyatsoona zvikanganiso zveplating mushure mekuita kwekupukuta kudzivirira zvigadzirwa zvisina kukodzera kubva mufekitori.Mainjiniya eAutoair vanoona otomatiki kukanganisa nerubatsiro rweruzivo rwesainzi yemifananidzo

FAQ:
Q1: Chii chinonzi pneumatic cylinder piston tsvimbo?
A: Iyo piston tsvimbo chinhu chakakosha uye chakakosha chikamu cheese hydraulic kana pneumatic cylinder.Iyo piston tsvimbo kazhinji ndeyekureba kwakamisikidzwa kweyakaomarara chrome yakaputirwa inotonhora yakapera simbi bhaa iyo inoendesa simba rakagadzirwa nepiston kuchikamu chemuchina chiri kuita basa.
Q2: Ndeipi musimboti wepneumatic cylinder piston tsvimbo?
A: Iyo pneumatic cylinder piston iri mucylinder inotakura kupinza kana kudhonza simba rinogadzirwa nemhepo, uye yakananga inoshanda pane pneumatic cylinder piston tsvimbo yakabatana nepiston, uyezve pneumatic cylinder piston tsvimbo inobatanidzwa kune inotakura workpiece kufamba. shure uye mberi.
Q3: Chii chinonzi mbishi chepneumatic cylinder piston tsvimbo yako
A: Kazhinji, iyo pneumatic cylinder piston tsvimbo yepneumatic cylinder ichasarudza 45# simbi seyakagadzirwa.Kana iyo silinda inogadzirwa ichida kushandiswa munzvimbo yakakosha, 304 simbi isina tsvina inogona zvakare kushandiswa
Q4: Sei uchisarudza 45 # simbi seyakagadzirwa zvinhu
A: 45# simbi ndeyepamusoro-mhando kabhoni structural simbi ine yakaderera kuoma uye nyore kucheka.Mushure mekudzima, kuoma kwayo kwepamusoro kunogona kusvika 45-52HRC.Uye inogona zvakare kuve nekuita zvirinani kucheka uye kusimba kwepamusoro, kuomarara uye humwe hunyoro hwemagetsi zvivakwa, saka ndechimwe chezvinhu zvinowanzo shandiswa kune shaft zvikamu.
Q5: Ndeipi machining maitiro eiyo pneumatic cylinder piston tsvimbo?
A: Kuti uwane yakagadzikana machining quality, manual straightening yepiston tsvimbo haibvumirwi mushure mokunge machining atanga.Naizvozvo, nzira yekururamisa inofanira kuitwa pamberi pekugadzira.Nekuda kwekusaomarara kusimba kweiyo workpiece, kutendeuka kwakashata uye kutendeuka kwakanaka kunofanirwa kuitwa panguva yekugadzira machining kuvandudza machining kurongeka.Iyo yekushanda modhi yepiston tsvimbo iri kudzokorora mutsara kufamba.Kuti uvandudze hupenyu hwesevhisi yepiston tsvimbo, kumusoro kunofanirwa kuve chrome-yakaputirwa kuti ivandudze kuoma kwayo kwepamusoro uye kupfeka kuramba.Mushure me chrome plating, kurapwa kwekukwenenzverwa kunodiwa kuti uwane hutsinye hwepamusoro, kuderedza friction factor, uye kugadzirisa chisimbiso kuita.Sezvo kukwenenzverwa kunenge kusingaite padhayamita yekunze yepiston tsvimbo, iyo workpiece inoda kuwana yakakwira pamusoro roughness pamberi pe chrome plating.Naizvozvo, zvinodikanwa kuti uwedzere nzira yakanaka yekukuya pamberi peiyo chrome plating process (kunyatso kugaya kunogona zvakare kunatsiridza kunamatira kwepamusoro kwechromium. ).Zvichienderana nekuongorora kuri pamusoro, iwo anonzwisisika maitiro ekugadzirisa episton tsvimbo ndeaya: kutwasanudza-rough kutendeuka-yakanaka kutendeuka-yakanaka kugaya-chrome plating-kupolishing.
Q6: Chii kupenya kwepneumatic cylinder piston tsvimbo
A: Munguva yekutendeuka, gomba repakati rinoita basa rekuisa rinoratidza imwe dhigirii yekupfeka.Kuti ive nechokwadi chekubatana kwemabenchmarks, gomba repakati rinofanirwa kuchekwa risati rakuya kuti ive nechokwadi chekugadzirisa kunaka.Paunenge uchikuya, kuedza kukuya kunofanira kuitwa kune denderedzwa rekunze pedyo nekuguma kwekutanga, uye kukuya kwepiston tsvimbo inogona kuitwa chete kana mamiriro ekumhanya achisangana nezvinodiwa zvekugadzirisa.Pamusoro pekuvandudza kurongeka kwedimensional, iyo yakanaka yekukuya maitiro inodawo kuwana yakakwirira pamusoro roughness pane yakashongedzwa nzvimbo yekuvandudza hukama hwechromium ions panguva ye electroplating process.Kuti uone kuti ukobvu hwechromium plating layer yepiston rod yekupedzisira yakafanana, kushata kwepamusoro mushure mekukuya kunofanirwa kunge kuri padyo nekushata kwepamusoro mushure mekugadzirwa kwechromium nekupukuta.Kana hutsinye hwepamusoro hwepiston tsvimbo ichida kuti ive yakakwirira, yakadai seRa <0.2 μm, inofanira kunge yakatsetseka.Wedzera super fine grinding kana polishing process mushure mekukuya.
