Nekukurumidza kusimukira kweindasitiri yesimbi, kuitira kuvandudza kubuda kwesimbi uye kuvandudza mwero wekushandiswa uye kugadzirwa kwechigayo, kuderedza nguva yekuvhara kwechigayo, kutora tungsten carbide roller ine hupenyu hurefu hwesevhisi chinhu chakakosha. nzira.

Chii chinonzi Tungsten Carbide Roller

Iyo simende carbide roller, inozivikanwawo secemented carbide roller ring, inoreva mupumburu wakagadzirwa netungsten carbide uye cobalt kuburikidza nehupfu metallurgical nzira. Iyo tungsten carbide roll ine mhando mbiri dzekubatanidzwa uye inosanganiswa. Iyo ine hukuru hwekuita, yakagadzikana mhando, yakakwirira yekugadzirisa kurongeka neakanakisa kupfeka kuramba uye yakakwirira kukanganisa kuramba. Carbide roller inoshandiswa zvakanyanya kutenderedza tsvimbo, waya, simbi yakarukwa uye isina musono pombi yesimbi, iyo inovandudza zvakanyanya kushanda kwechigayo.

Kuita Kwepamusoro KweTungsten Carbide Roller

Iyo carbide roll ine kuomarara kwepamusoro uye kukosha kwayo kwekuoma kunosiyana diki netembiricha. Iko kukosha kwekuoma pasi pe700 ° C ndeye 4 nguva yakakwirira kudarika simbi yepamusoro. Iyo elastic modulus, iyo inomanikidza simba, iyo inokotama simba, iyo yekupisa conductivity zvakare yakakwira ka1 pane simbi yekushandisa. Sezvo thermal conductivity ye cemented carbide roll yakakwira, kupisa kwekushisa kwekuita kwakanaka, kuitira kuti pamusoro pemupumburu uri pasi pekushisa kwepamusoro kwenguva pfupi uye nekudaro nguva yekupisa-yepamusoro-yekupisa kwekusvibiswa kunokuvadza mumvura inotonhorera uye. mupumburu ipfupi. Naizvozvo, tungsten carbide rollers inoshingirira mukuora uye kutonhora nekupisa kuneta kupfuura mudziyo wesimbi rollers.

Kuita kwetungsten carbide rollers kune hukama nezviri mukati mebhondi yesimbi chikamu uye saizi ye tungsten carbide zvimedu. Iyo tungsten carbide inenge 70% kusvika 90% yehuwandu hwehuwandu uye huwandu hwehuwandu hwehuwandu huri μm hwe 0.2 kusvika 14. Kana iyo metal bond content ichiwedzerwa kana kuwedzera chidimbu che tungsten carbide, kuoma kwe simenti carbide kunoderera uye kuoma kunovandudzwa. Simba rekukotama retungsten carbide roller mhete inogona kusvika 2200 MPa. Iko kuoma kwesimba kunogona kusvika (4 ~ 6) × 106 J / ㎡, uye iyo HRA iri makumi manomwe nesere kusvika makumi mapfumbamwe.

Iyo tungsten carbide roller inogona kukamurwa kuita mhando mbiri dzekubatanidza uye composite zvinoenderana nechimiro chechimiro. Integral tungsten carbide roller yakashandiswa zvakanyanya mu pre-chaizvo kukungurutsira uye kupedzisa kumira kweyepamusoro-kumhanya waya inotenderedza zvigayo. Iyo inosanganiswa cemented carbide roller inoumbwa kuburikidza ne tungsten carbide uye zvimwe zvinhu. Iro composite carbide rollers inokandwa zvakananga mumugodhi we roller, iyo inoshandiswa kune guyo rinoputika rine mutoro unorema.

Machining Nzira yeTungsten Carbide Roller uye Sarudzo Mitemo Yekucheka Zvishandiso Zvayo

Kunyangwe iyo tungsten carbide zvinhu zviri nani pane zvimwe zvinhu, zvakaoma kuita machining nekuda kwekuomarara kwakanyanya uye inonyanya kushandiswa muindasitiri yesimbi.

1.Nekuoma

Paunenge uchigadzira tungsten carbide rolls nekuoma kudiki pane HRA90, sarudza HLCBN material kana BNK30 material tool yehuwandu hwekutendeuka uye chishandiso hachina kuputswa. Paunenge uchigadzira carbide roller nekuoma kwehukuru kupfuura HRA90, CDW025 diamond chishandiso chinowanzo sarudzwa kana kukuya neresin diamond vhiri. Kazhinji, iyo yakakwira kuomarara ndiko, zvinhu zvacho zviri crisper, saka zvine hungwaru pakucheka zvinhu zvekuomarara zvakanyanya uye iyo chaiyo yakachengeterwa kupedzisa kugaya mvumo.

2.Iyo machining mvumo uye nzira dzekugadzirisa

If iyo yekunze inogadzirwa nemichina uye mvumo yakakura, kazhinji inotora zvinhu zveHLCBN kana BNK30 zvinhu kuti zvigadziriswe zvine mwero, wozokuya negumbo. Kune madiki machining allowance, roller inogona kukuyiwa yakananga negumbo rekukuya kana profiling yakagadziriswa nedhaimani maturusi. Kazhinji, kucheka kumwe kukuya kunogona kuvandudza machining kunyatsoshanda uye nzira yekucheka inonyanya kubatsira mukuvandudza kugadzirwa kwekutungamira nguva.

3.Pasivating kurapwa

Paunenge uchigadzira tungsten carbide roller, kurapa kwekupfuura kunodiwa kudzikisa kana kubvisa kukosha kwekupinza, nechinangwa chekupfava uye kutsvedzerera nekusimba kwakanyanya. Nekudaro, kurapwa kwepassivation hakufanirwe kunge kwakakura kwazvo, nekuti iyo yekuonana pamusoro pechishandiso blade yakakura mushure mekuita passivation uye kushomeka kwekucheka kunowedzerawo, izvo zviri nyore kukonzera kutsemuka, kukuvadza workpiece.

Chii Chinofanira Kutariswa Nezve Kugadzira uye Kushandisa Tungsten Carbide Roller

Mumakore achangopfuura, tungsten carbide rollers vakawana kushandiswa kwakawanda uye kwakawanda mukugadzirwa kwesimbi nekushanda kwavo kwakanaka. Nekudaro, kuchine zvimwe zvinhu mukugadzira uye kushandiswa kwecarbide rolls.

1. Gadzira rudzi rutsva rwe roller shaft material. Yakajairwa ductile iron roller shafts ichave yakaoma kutsungirira yakakura kutenderedza simba uye kuunza yakakura torque. Saka yakakwirira-inoshanda simende carbide composite roll shaft zvinhu zvinofanirwa kugadzirwa.

2. Munguva yekugadzirwa kwecarbide rollers, iyo yakasara yekushungurudzika kwekushisa kunokonzerwa nekuwedzera kwekushisa pakati pesimbi yemukati uye yekunze cemented carbide inofanira kuderedzwa kana kubviswa. Iyo carbide yakasara yekupisa kushushikana chinhu chakakosha chinokanganisa hupenyu hwe roller. Nokudaro, iyo coefficient of thermal expansion difference pakati pesimbi yakasarudzwa yemukati uye yekunze cemented carbide inofanira kuva shoma sezvinobvira, paunenge uchifunga kubvisa kusara kwekupisa kwemhepo ye carbide roller ring kuburikidza nekupisa kupisa.

3. Nekuda kwekusiyana kwesimba rekukunguruka, torque inotenderedza, kupisa kwekushisa kwekuita pamaraki akasiyana, maracks akasiyana anofanirwa kutora mamakisi akasiyana etungsten carbide rollers kuti ave nechokwadi chekuenderana kwesimba, kuoma, uye kuomarara kusimba.

Summary

Nekukunguruka kwewaya, tsvimbo, tungsten carbide roller inotsiva yakajairwa simbi simbi rolls uye alloy simbi rolls, yakaratidza hukuru hwakawanda, nekuenderera mberi kwekuvandudzwa kwemaitiro ekugadzira roller uye kushandisa tekinoroji, icharamba ichiwedzera mashandisirwo ecarbide roller mhete. uye ivo vanozonyanya kukosha mukuumburudza machining neyakakura maapplication.
