Nei tichifunga kuti titanium alloy chinhu chakaoma kuchina? Nekuda kwekushaiwa kwekunzwisisa kwakadzama kwemaitiro ayo ekugadzirisa uye chiitiko.
1. Physical Phenomena yeTitanium Machining
Simba rekucheka retitanium alloy processing rinongokwira zvishoma pane iro resimbi ine kuoma kwakafanana, asi chiitiko chemuviri chekugadzirisa titanium alloy chakaomarara kupfuura icho chekugadzira simbi, izvo zvinoita kuti titanium alloy kugadzirisa kutarisana nematambudziko makuru.
Iyo yekupisa conductivity yeakawanda titanium alloys yakadzikira, chete 1/7 yesimbi uye 1/16 yealuminium. Naizvozvo, kupisa kunogadzirwa mukugadzira titanium alloy hakuzokurumidza kuendeswa kune workpiece kana kutorwa nemachipisi, asi kunounganidzwa munzvimbo yekucheka, uye tembiricha inogadzirwa inogona kunge yakakwira kusvika 1000 ° C, zvichikonzera kucheka kwechishandiso chekupfeka, kutsemuka uye kufa nekukurumidza. Kuvaka-kumucheto kuvaka-up, kutaridzika nekukurumidza kwemapendero akasakara, inoburitsa kupisa kwakawanda munzvimbo yekucheka, kuwedzera kupfupisa hupenyu hwechishandiso.
Kupisa kwepamusoro kunogadzirwa panguva yekucheka kunoparadzawo kutendeseka kwepamusoro kwetitanium alloy zvikamu, zvichiita kuti kuderera kweiyo geometric yakarurama yechikamu uye basa rinoomesa chiitiko chinoderedza zvakanyanya kuneta kwayo simba.
Iyo elasticity yetitanium alloys inogona kubatsira kune chikamu chekuita, asi panguva yekucheka, iyo elastic deformation yeworkpiece ndicho chikonzero chakakosha chekudengenyeka. Kudzvinyirira kwekucheka kunokonzera "elastic" workpiece kusiya chigadziro uye kudzorerazve, kuitira kuti kukakavara pakati pechombo uye workpiece kwakakura kudarika chiito chekucheka. Iyo friction process inoburitsawo kupisa, izvo zvinowedzera dambudziko rekushata kwekupisa kwetitanium alloys.
Dambudziko iri rinotonyanya kuipa kana uchigadzira mativi akatetepa-ane madziro kana mhete anoremara nyore. Harisi basa riri nyore kugadzira titanium alloy dzakatetepa-madziro zvikamu kune zvinotarisirwa dimensional kurongeka. Nekuti kana iyo workpiece zvinhu zvinosundirwa kure nechishandiso, iyo yemuno deformation yemadziro mutete yakapfuura iyo elastic renji kuti ibudise epurasitiki deformation, uye kusimba kwezvinhu uye kuoma panzvimbo yekucheka kunowedzera zvakanyanya. Panguva ino, machining payakatemerwa kucheka kumhanya inova yakanyanya kukwirira, izvo zvinotungamira mukupfekwa kwechishandiso.
"Kupisa" ndiyo "mhosva" yekuoma kwekugadzirisa titanium alloys!
2. Tekinoroji ruzivo rwekugadzirisa titanium alloys
Pahwaro hwekunzwisisa magadzirirwo etitanium alloys, pamwe neruzivo rwekare, iyo huru maitiro ekuziva magadzirirwo etitanium alloys ndeaya anotevera:
(1) Inopinza ine yakanaka kona geometry kuderedza simba rekucheka, kucheka kupisa uye deformation yeworkpiece.
(2) Chengetedza chikafu chenguva dzose kuti urege kuoma kweworkpiece. Chishandiso chinofanira kugara chiri mukudya kwekudya panguva yekucheka. Iyo radial yekucheka huwandu ae inofanirwa kunge iri 30% yeradius panguva yekugaya.
(3) High-pressure uye yakakura-inoyerera yekucheka mvura inoshandiswa kuve nechokwadi chekudziya kwekugadzikana kwemaitiro ekugadzira machining uye kudzivirira iyo workpiece pamusoro kubva pakuderera uye kukuvara kwechishandiso nekuda kwekupisa kwakanyanya.
(4) Chengetedza chidimbu chekucheka cheblade chakapinza, mapanga asina kujeka ndiwo anokonzera kupisa kwekupisa uye kupfeka, izvo zvinogona kutungamirira nyore kukundikana kwemapanga.
(5) Kugadziridza mune yakapfava mamiriro etitanium alloy sezvinobvira, nekuti zvinhu zvinova zvakanyanya kuoma kugadzirisa mushure mekuoma, kupisa kurapwa kunovandudza kusimba kwechinhu uye kunowedzera kupfeka kweblade.
(6) Shandisa mhino yakakura kana chamfer kuti ucheke zvakanyanya sezvinobvira mumucheto wekucheka. Izvi zvinogona kuderedza simba rekucheka uye kupisa panzvimbo imwe neimwe uye kudzivirira kuparara kwenzvimbo. Pakugaya titanium alloys, pakati pematanho ekucheka, kumhanya kwekucheka kune simba guru pane chishandiso hupenyu vc, inoteverwa neiyo radial yekucheka huwandu (milling kudzika) ae.
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:

3. Kugadzirisa matambudziko ekugadzirisa titanium kutanga kubva kune blade
Iyo blade groove inopfeka inoitika panguva yekugadziriswa kwetitanium alloy kupfekedzwa kwenzvimbo kumashure uye kumberi pamwe nekudzika kwegwara rakachekwa, iro rinowanzo kukonzerwa neyakaomeswa layer yakasiiwa neyakapfuura kugadzirisa. Iko kemikari yekuita uye kupararira pakati pechishandiso uye workpiece zvinhu pane tembiricha yekugadzira inopfuura 800 ° C zvakare chimwe chezvikonzero zvekuumbwa kwekupfeka kwegroove. Nokuti panguva yekugadzira, titanium molecules ye workpiece inounganidza pamberi pechidzitiro, uye "yakasungirirwa" kune blade pasi pekumanikidzwa kwepamusoro uye kupisa kwepamusoro, kuumba muganhu wakavakwa. Kana yakavakirwa-mupendero inosvuura kubva kumucheto wekucheka, inobvisa iyo carbide coating yekuisa, saka titanium machining inoda yakakosha yekuisa zvinhu uye geometries.
4. Chigadziro chekushandisa chinokodzera titanium machining
Chinangwa chetitanium alloy processing kupisa. Kuwanda kwemvura yekucheka kwepamusoro-soro kunofanira kusaswa pamucheto wekucheka panguva uye yakarurama kuti ibvise kupisa nokukurumidza. Kune akasiyana zvimiro zvemilling cutters anonyanya kushandiswa titanium alloy processing pamusika.
