Ndeapi mabhenefiti eiyo mineral cast marble bed machining centre?
Mineral castings (yakagadzirwa nevanhu granite aka resin kongiri) yakagamuchirwa zvakanyanya muindasitiri yezvishandiso zvemuchina kweanopfuura makore makumi matatu sechinhu chekugadzira.
Zvinoenderana nenhamba, muEurope, mumwe chete kubva kune gumi ese maturusi emuchina anoshandisa mineral castings semubhedha.Nekudaro, kushandiswa kweruzivo rusina kufanira, ruzivo rusina kukwana kana rusina kururama kunogona kutungamirira mukufungirana uye kusarura pamusoro peMineral Castings.Naizvozvo, kana uchigadzira michina mitsva, zvinodikanwa kuongorora zvakanakira nekuipira kwemamineral castings uye kuenzanisa nezvimwe zvinhu.
Hwaro hwemichina yekuvaka inowanzo patsanurwa kuita simbi yakakandwa, mineral casting (polymer uye / kana reactive resin kongiri), simbi / welded chimiro (grouting / isiri-grouting) uye dombo rechisikigo (senge granite).Chinhu chimwe nechimwe chine hunhu hwayo, uye hapana chakakwana chechimiro.Chete nekuongorora zvakanakira uye zvisingabatsiri zvechinyorwa zvinoenderana nezvinodiwa zvechimiro chechimiro, iyo yakanaka yekugadzira zvinhu inogona kusarudzwa.
Iwo maviri akakosha mabasa ezvimiro zvezvimiro-kuvimbisa iyo geometry, chinzvimbo uye simba kunyudzwa kwezvikamu, zvichiteerana zvinoisa pamberi pekuita zvinodiwa (static, dynamic uye thermal performance), zvinoshanda/zvimiro zvinodiwa (kurongeka, huremu, ukobvu hwemadziro, kureruka kwegwara regwara) kuisirwa zvinhu, midhiya inotenderera sisitimu, logistics) uye mutengo zvinodiwa (mutengo, huwandu, kuwanikwa, system maitiro).
I. Mashandiro ezvinodiwa zvezvimiro zvezvinhu
1. Static maitiro
Chiyero chekuyera static properties yehwaro kazhinji kuoma kwezvinhu-kuderera kwekugadzirisa pasi pemutoro, pane simba guru.Kune static elastic deformation, mineral castings inogona kufungidzirwa se isotropic homogeneous zvinhu zvinoteerera mutemo waHooke.
Iyo density uye elastic modulus yemaminerari castings inoteerana 1/3 yeaya eakakanda simbi.Sezvo mineral castings uye masimbi ekukanda ane kuoma kwakafanana kwakafanana, pasi pehuremu hwakafanana, kusimba kwesimbi yekukanda uye mineral castings kwakafanana pasina kufunga nezvesimba rechimiro.Muzviitiko zvakawanda, iyo dhizaini madziro makubvu emaminerari castings anowanzo 3 zvakapetwa neayo esimbi castings, uye dhizaini iyi haizokonzerese matambudziko maererano nemakanika echigadzirwa kana kukanda.Mineral castings akakodzera kushanda munzvimbo dzakadzikama dzinotakura kudzvanywa (semuenzaniso mibhedha, zvitsigiro, makoramu) uye hazvina kukodzera semutete-madziro uye/kana mafuremu madiki (semuenzaniso matafura, mapallet, maturusi ekuchinja, ngoro, zvitsigiro zvemaspindle).Huremu hwezvikamu zvezvimiro zvinowanzoganhurwa nemidziyo yevanogadzira zvicherwa, uye zvigadzirwa zvekukanda zvicherwa pamusoro pematani gumi neshanu hazviwanzo.
2. Dynamic maitiro
Iyo yakakura yekutenderera kumhanya uye / kana kukwidziridza shaft, iyo inonyanya kukosha kuita kwesimba kwemuchina.Kurumidza kumira, kukurumidza kutsiva chishandiso, uye yakakwirira-yekumhanyisa feed inoenderera ichisimbisa mechanic resonance uye ine simba kunakidzwa kwemuchina zvimiro zvikamu.Kuwedzera kune dimensional dhizaini yechikamu, kutsauswa, kugovera kwakawanda, uye kusimba kwakasimba kwechikamu kunokanganisa zvakanyanya nekunyorovesa zvinhu zvemukati.
Kushandiswa kwemamineral castings kunopa mhinduro yakanaka kune aya matambudziko.Nekuti inotora vibrations kakapetwa ka10 pane yechinyakare simbi yakakandwa, inogona kuderedza zvakanyanya amplitude uye yakasikwa frequency.
Mukuita machining senge machining, inogona kuunza kunyatsojeka, kunaka kwepamusoro, uye hupenyu hurefu hwematurusi.Panguva imwecheteyo, maererano nekukanganisa kweruzha, mamineral castings akaitwawo zvakanaka kuburikidza nekuenzanisa uye kusimbiswa kwezvigadziko, kutapurirana castings uye zvishongedzo zvezvinhu zvakasiyana zveinjini hombe uye centrifuges.Zvinoenderana nemhedzisiro yekuongororwa kwenzwi, iyo mineral casting inogona kuwana kudzikiswa kwenzvimbo kwe20% muyero yekumanikidza.
3. Thermal properties
Vanamazvikokota vanofungidzira kuti inosvika 80% yekutsauswa kwemidziyo yemuchina inokonzerwa nekupisa kwemafuta.Kukanganisa kwemaitiro senge mukati kana kunze kwekupisa kwemukati, preheating, kushandura workpieces, nezvimwe ndizvo zvese zvinokonzeresa kupisa kwemafuta.Kuti ukwanise kusarudza zvinhu zvakanakisisa, zvakakosha kujekesa zvinhu zvinodiwa.Iyo yakanyanya kupisa chaiyo uye yakaderera kupisa conductivity inobvumira mineral castings kuve neyakanaka yekupisa inertia kune yenguva pfupi tembiricha pesvedzero (sekuchinja maworkpieces) uye ambient tembiricha kuchinja.Kana kukurumidza kupisa kwekutanga kuchidikanwa semubhedha wesimbi kana tembiricha yemubhedha yakarambidzwa, kupisa kana kutonhora zvishandiso zvinogona kukandwa zvakananga muminerari yekukanda kudzora tembiricha.Kushandisa rudzi urwu rwekutsiva tembiricha mudziyo unogona kuderedza deformation inokonzerwa nekurudziro yekushisa, iyo inobatsira kuvandudza iko kurongeka nemutengo unonzwisisika.
II.Zvinodiwa zvekushanda uye zvemaitiro
Kuvimbika chinhu chinosiyanisa chinosiyanisa mineral castings kubva kune zvimwe zvinhu.Iyo yakanyanya kupisa tembiricha yekukanda mineral castings ndeye 45 ° C, uye pamwe nepamusoro-chaiyo molds uye tooling, zvikamu uye mineral castings zvinogona kukandwa pamwechete.
Maitiro epamberi ekukanda zvakare anogona kushandiswa pane zvicherwa zvekukanda blanks, zvichikonzera kukwira chaiko uye nzvimbo dzenjanji dzisingade machining.Kufanana nezvimwe zvigadziko zvigadzirwa, mineral castings inoenderana neyakajeka dhizaini mitemo.Ukobvu hwemadziro, zvinhu zvinotakura zvinhu, kuisirwa mbabvu, kurodha uye kuburitsa nzira dzese dzakasiyana kubva kune zvimwe zvinhu kusvika pamwero wakati, uye dzinofanirwa kutariswa pachine nguva panguva yekugadzira.
III.Zvinodiwa mutengo
Kunyange zvazvo zvakakosha kufunga kubva kune unyanzvi hwekuona, kushandiswa kwemari kunowedzera kuratidza kukosha kwayo.Kushandisa mineral castings kunobvumira mainjiniya kuchengetedza zvakakosha kugadzirwa uye mari yekushandisa.Pamusoro pekuchengetedza pamitengo yekugadzira, kukanda, gungano rekupedzisira, uye kuwedzera mitengo yezvinhu (yekuchengetedza uye yekufambisa) zvese zvakaderedzwa zvinoenderana.Tichifunga nezvebasa repamusoro-soro rekuita mineral castings, inofanirwa kutaridzirwa sepurojekiti yose.Muchokwadi, zvinonzwisisika kuita kuenzanisa kwemutengo kana chigadziko chakaiswa kana pre-yakaiswa.Mutengo wekutanga wakakwira mutengo wemaminerari ekukanda molds uye tooling, asi mutengo uyu unogona kuderedzwa mukushandiswa kwenguva refu (500-1000 zvidimbu / simbi mold), uye kushandiswa kwepagore kunenge 10-15 zvidimbu.
IV.Kuwanda kwekushandisa
Sechinhu chechimiro, mamineral castings anogara achitsiva zvechinyakare zvimiro, uye kiyi yekukura kwayo nekukurumidza iri mukukanda zvicherwa, mold, uye yakagadzika zvisungo zvekubatanidza.Parizvino, mamineral castings ave achishandiswa zvakanyanya muminda mizhinji yezvishandiso zvemuchina senge muchina wekukuya uye nekumhanyisa machining.Vagadziri vemuchina wekukuya vanga vari mapiyona muchikamu chemidziyo yekushandisa vachishandisa mineral castings yemibhedha yemuchina.Semuenzaniso, makambani ane mukurumbira pasi rose akadai seABA z&b, Bahmler, Jung, Mikrosa, Schaudt, Stude, etc. vagara vachibatsirwa kubva mukunyorovesa, kupisa inertia uye kutendeseka kwemamineral castings kuti vawane kurongeka kwepamusoro uye kunaka kwepamusoro kwepamusoro mukukuya. .
Nekuramba kuchiwedzera mitoro ine simba, mamineral castings ari kuwedzera kufarirwa nemakambani anotungamira pasi rose mumunda wezvigayo zvekushandisa.Iyo mineral casting bed ine yakanyanya kuomarara uye inogona kunyatso bvisa iyo simba rinokonzerwa nekumhanyisa kweiyo linear mota.Panguva imwecheteyo, iyo organic musanganiswa yeakanaka vibration absorption kuita uye mutsara mota inogona kuvandudza zvakanyanya kunaka kweiyo workpiece uye hupenyu hwesevhisi yevhiri rekukuya.
