Nzira yekusarudza cemented carbide blade?

Carbide insert chinhu chinoshandiswa zvakanyanya chekushandisa chepamusoro-kumhanya machining. Rudzi urwu rwezvinhu runogadzirwa nehupfu metallurgy uye ine hard carbide particles uye soft metal adhesives. Parizvino, kune mazana ezvinyorwa zvakasiyana zveWC-based cemented carbide, mazhinji ayo anoshandisa cobalt sebhainda, nickel uye chromium zvakare zvakajairika binder zvinhu, uye zvimwe alloy zvinhu zvinogona zvakare kuwedzerwa.

Sarudzo yecemented carbide blade: Kutendeuka kwesimende carbide blade ndiyo nzira huru yekusimwa carbide processing tekinoroji, kunyanya muindasitiri inorema yekugadzira michina, kusarudzwa kwechishandiso kwakakosha. Zvinoenderana neyakasiyana yekugadzira michina, kana ichienzaniswa neyakajairika machining, inorema kutendeuka ine hunhu hwekudzika kukuru kwekucheka, kuderera kwekucheka kumhanya uye kunonoka kwekudya. Iyo machining mvumo kune rumwe rutivi inogona kusvika 35-50 mm. Pamusoro pezvo, nekuda kwekusagadzikana kweiyo workpiece, kusagovewa kwakaenzana kwehuwandu hwematurusi emuchina uye kusaenzana kwezvikamu uye zvimwe zvinhu, kuzununguka kwemvumo yemuchina kunoita kuti iyo dhizaini yekuenzanisa idye yakawanda yenguva yerunhare. uye nguva yekubatsira. Naizvozvo, kuti tigadzirise zvikamu zvinorema uye nekuvandudza kugadzirwa kana chiyero chekushandisa chemichina yemidziyo, isu tinofanirwa kutanga nekuwedzera ukobvu uye chiyero chekudya chechikamu chekucheka. Isu tinofanirwa kutarisisa kusarudzwa kwekucheka maparamendi uye mashizha, kuvandudza chimiro uye geometry yemashizha, uye funga nezvezvinhu zvemashizha. Simba maitiro, nokudaro kuwedzera kutema parameters uye zvakanyanya kuderedza kushanda nguva.

Izvo zvinowanzoshandiswa blade zvinhu zvinosanganisira high-speed steel, cemented carbide, ceramics, nezvimwewo. Kudzika kukuru kwekucheka kunogona kusvika 30-50mm, uye mvumo haina kuenzana. Ikoko kune yakaomeswa layer pamusoro peiyo workpiece. Muchikamu chekugadzira chakakasharara, kupfeka kweblade kunonyanya kuitika muchimiro cheabrasive kupfeka Kumhanya kwekucheka kunowanzo 15-20 m/min. Kunyangwe kukosha kwekumhanya kuri kusanganisa pa chip, tembiricha yepamusoro yekucheka inoita nzvimbo yekubatanidza pakati pechip uye yepamberi chishandiso chepamusoro munzvimbo yemvura, nekudaro kuderedza kukweshera uye kuvharidzira kuunganidzwa kwechizvarwa chekutanga chemachipisi. Iyo blade zvinhu zvichange zvisingapfeki uye zvisingaite. Iyo ceramic blade ine yakanyanya kuoma, asi yakaderera kukotama simba uye yakaderera maitiro kuoma. Haikodzeri kutendeuka kukuru uye ine mipendero isina kuenzana. Cemented carbide ine zvakatevedzana zvakanakira senge "yakakwira kupfeka kuramba, simba rekukotama rakakwirira, kusimba kwakanaka uye kuomarara kwakanyanya", nepo friction coefficient ye simende carbide yakaderera, inogona kuderedza simba rekucheka uye tembiricha yekucheka, uye inovandudza zvakanyanya kusimba. yebadza. Inokodzera rough machining emhando dzakaoma zvinhu uye inorema kutendeuka. Icho chisarudzo chakanaka chekushandura blade zvinhu.

Kuvandudza kumhanyisa kumhanyisa kweakaiswa simende carbide mumichina inorema ndechimwe chezvinhu zvakakosha zvekuvandudza hunyanzvi hwekugadzira uye kupfupisa kutenderera kwekugadzira. Mukuita uku, huwandu hukuru hwekusara hunochekwa kuita sitiroko dzinoverengeka, uye kudzika kwesitiroko imwe neimwe kudiki kwazvo. Kuita kwekucheka kweblade kunogona kuvandudza zvakanyanya kumhanya kwekucheka, nekudaro kunatsiridza kugona kwekugadzira, kuwedzera hupenyu hwesevhisi, uye kuderedza mitengo uye purofiti.
